S&C Series 2000 Circuit-Switchers
Model 2010 — With Horizontal Interrupters and
Outdoor Transmission (69 kV through 230 kV) Vertical-Break Power-Operated Disconnect
GENERAL
Interrupters
Series 2000 Circuit-Switchers employ single-gap SF
6
puffer-type interrupters designed to close the circuit in
6 cycles, interrupt the circuit in 6 cycles, and maintain
rated dielectric strength when open. These dual-function
interrupters are factory-filled to full pressure under con-
trolled conditions and then permanently sealed. Field fill-
ing is neither necessary nor possible, thus eliminating the
risk of contaminating the interrupting medium.
Operator
The interrupters are driven by a single stored-energy
mechanism located at ground level in a 48-volt dc, 125-volt
dc, or 115-volt 60-hertz operator furnished with the Cir-
cuit-Switcher. Refer to the “STANDARD FEATURES”
table on page 6, and also Figures 15 and 17. This operator
includes the following features:
•
Trip and close push buttons located inside operator
enclosure.
•
Manual trip lever, for tripping interrupters in the event
control voltage has been lost.
•
Manual charging handle, for opening disconnect after
interrupters have been manually tripped open—in the
event control voltage has been lost.
• Charged and discharged indicators for stored-energy
mechanism.
•
Non-reset electric operation counter.
•
Eight nonadjustable single-pole double-throw auxil-
iary-switch contacts which follow the interrupters.
•
Weatherproof, dustproof enclosure.
•
Decoupling mechanism which allows decoupling and
locking of disconnect-blade power train in the open
position, permitting operational checkout of interrupt-
ers, stored-energy mechanism, and relaying equipment
without closing the high-voltage circuit.
•
Two individually adjustable auxiliary-switch contacts
which follow the disconnect-blade power train and
operator when coupled, operator only when decou-
pled.
The mechanism in the operator has an instantaneous
trip-free capability: should the Series 2000 Circuit-
Switcher be inadvertently closed into a fault sensed by
user-furnished relaying, the mechanism will trip immedi-
ately. To accomplish trip-free operation, the mechanism
utilizes two spring assemblies: one for closing, one for
opening. Both springs are charged by the operator motor
before the Series 2000 Circuit-Switcher can be closed.
Recharging time after a trip operation is approximately
5 seconds for Circuit-Switchers rated 69 kV through
138 kV, and approximately 10 seconds for Circuit-Switch-
ers rated 161 kV and 230 kV.
Power Train
The operator directly drives the interrupters open and
closed through a simple high-speed power train leading
from the top of the operator, through a horizontal inter-
phase linkage enclosed in a steel-sheathed box-type base,
to reciprocating-action insulated operating rods which
pass through the center of insulating support columns. A
transfer linkage at the top of each insulating support
column converts the vertical reciprocating motion of the
operating rod into horizontal reciprocating motion, to
drive the interrupter.
The operator also drives the disconnect open and
closed through a low-speed power train which rotates the
insulating support columns. The disconnect on models
rated 69 kV through 138 kV is capable of opening and clos-
ing without hesitation under
³⁄₄ -inch ice formation. The
disconnect on models rated 161 kV and 230 kV is capable
of opening without hesitation under
³⁄₄ -inch ice formation
and of closing without hesitation under
¹⁄₂ -inch ice forma-
tion. A decoupling mechanism allows decoupling and
locking of the disconnect-blade power train in the open
position, permitting operational checkout of the interrupt-
ers, the stored-energy mechanism, and the relaying equip-
ment without closing the high-voltage circuit.
Permanently lubricated bearings are used throughout
both the high-speed and low-speed power trains. The insu-
lating support columns are filled with a lubricated dielec-
tric filler which prevents contamination from affecting the
dielectric integrity of the column or the insulated operat-
ing rod. An aerator is utilized at the upper end of each
insulating support column to eliminate water being
pumped-in due to pressure differentials caused by tem-
perature cycling.

BEFORE STARTING INSTALLATION
Checking the Shipment
An S&C catalog drawing will be found in a water-resistant
envelope attached to the plastic bubble-wrap around one
of the insulating support columns. Study this drawing
carefully and check the bill of material to verify that all
parts are at hand.
The Model 2010 Series 2000 Circuit-Switcher shipment
should include the following items, as shown in Figures 2
and 5:
1. Three pole-units, each consisting of an interrupter,
integral disconnect blade, insulating support column,
support insulator, and channel base—all factory-
assembled and adjusted.
2. A single cross base, enclosing the high-speed inter-
phase power train which drives the interrupters.
3. The appropriate number of mounting pedestals, com-
plete with support arms and channels. A single pedes-
tal is used for Circuit-Switchers rated 69 kV (with 48-
inch phase spacing); a set of two pedestals is used for
Circuit-Switchers rated 69 kV (with 84-inch phase spac-
ing), 115 kV, and 138 kV; and a set of three pedestals is
used for Circuit-Switchers rated 161 kV and 230 kV.
4. A Series 2000 Circuit-Switcher Operator.
5. A low-speed interphase power train which drives the
disconnect blades.
6. A container of miscellaneous operating-mechanism
components and hardware—all individually identified.
7. Any optional features specified, such as a grounding
switch.
Gas-Pressure Indicator
Series 2000 Circuit-Switchers have sealed interrupters
containing gas under pressure. Low gas pressure is sig-
naled by a red target in the gas-pressure indicator at the
terminal end of the interrupter.
DO NOT INTERMIX COMPONENTS FROM
DIFFERENT INSTALLATIONS
Series 2000 Circuit-Switchers are completely fac-
tory-assembled and thoroughly tested. To speed
installation and maintain proper adjustment of the
Circuit-Switcher and its operator, it is imperative
that components belonging to a specific Circuit-
Switcher installation not be intermixed with compo-
nents belonging to a different installation. For this
reason, each Series 2000 Circuit-Switcher is serially
numbered. This serial number appears on the indi-
vidual pole-units, the cross base, the mounting ped-
estals, and the operator.
It is further important that components from dif-
ferent installations not be intermixed in that S&C
maintains an historical record—by serial num-
ber—of every Circuit-Switcher produced. This
record lists information pertinent to each installa-
tion, such as application, date of shipment, and any
service performed by S&C field service specialists.
This record is invaluable when questions arise rela-
tive to modifications or replacements.
Please complete and mail the Circuit-Switcher
registration card (enclosed in a vinyl envelope
located inside the operator) after the Circuit-
Switcher has been installed. The information
requested on this card is vital to ensure prompt
notification in the event field modifications are
needed.
Storage
If the Circuit-Switcher must be stored before installation,
keep it in a clean, dry, corrosion-free area to protect it
from damage. If storing outside or in a non-climate con-
trolled area, connect control power to the space heater
inside the Circuit-Switcher Operator per wiring diagram.
Inspect the Circuit-Switcher regularly when stored for
prolonged periods.
NOTICE
The Series 2000 Circuit-Switcher Operator is equipped
with a space heater that must be energized during
storage to prevent condensation and corrosion within
the operator enclosure.
NOTICE
Loss of gas pressure may result in improper interrupt-
ing action. The red target should not be visible. If the
red target is visible, stop the installation and notify
S&C Electric Company.

BOLTED AND PINNED CONNECTIONS
A typical bolted connection for field assembly
requires a flat washer under the cap screw and one
under the nut. In instances where self-locking hex
nuts are specified, it is essential that the threads of
the associated cap screws be lubricated with a gen-
eral-purpose grease, to facilitate tightening. All pins
used in the field assembly should also be lubricated
to facilitate insertion.
Step 1
Cut the steel straps that bind the mounting pedestals to
the cross base, the straps that bind the container of mis-
cellaneous operating-mechanism components and hard-
ware, and the straps that bind the pole-units. Also remove
the wood bracing between the pole-unit terminal pads.
See Figure 2. For Circuit-Switchers rated 161 kV and
230 kV: Remove the lifting angles attached to the pole-unit
channel bases; retain these lifting angles and associated
hardware for re-use in Step 13.
ÇCAUTION
Do not remove the containers from the interrupters,
or the plastic bubble-wrap from the insulating sup-
port columns, until the installation has been
completed.

Step 3
Attach four suitable lifting slings to the cross base. See
Figure 4. Unbolt the base from the shipping skid and lift
the base atop the mounting pedestals, as shown on the
catalog drawing. Avoid sudden starts and stops. Verify
that the switch-position indicator on the base is visible on
the desired side (this is also the side on which the opera-
tor door will open).
Step 4
Loosely bolt the cross base to the mounting pedestals
using the ⁵⁄₈—112¹⁄₄hex-head galvanized steel cap
screws, flat washers, and self-locking hex nuts furnished.
Then— using a level—verify that the cross base is hori-
zontal, both lengthwise and side-to-side; adjust the lower
set of anchor-bolt nuts at the pedestals to achieve this
condition
Step 5
Securely bolt the cross base to the mounting pedestals.
Shims are furnished and should be installed as necessary
between the cross base and the mounting pedestals, to
compensate for any irregularities greater than ¹⁄₈ inch
between the mating surfaces.
Step 6
Check the lower set of anchor-bolt nuts at each mounting
pedestal to verify that all nuts are in contact with the
bottom of the pedestal. Hand-tighten these anchor-bolt
nuts as necessary. Then securely tighten the upper set of
anchor-bolt nuts at each mounting pedestal.

Step 7
Loosen the ¹⁄₂—131¹⁄₄galvanized steel cap screws, flat
washers, and nuts which are used to attach the bottom
plates to the underside of the cross base. Remove the
plates and place them and their hardware aside on a clean
surface.
Also remove the ³⁄₄-inch stainless-steel pin and cotter
pin from the interphase drive lever enclosed in the cross
base. See Figure 10. Retain these pins for re-use in
Step 17.
Step 8
Wrap a lifting sling around the stored-energy housing of
the operator, as shown in Figure 5 (left). Now carefully
raise the operator to the upright position so that it rests
on its base skid, as shown in Figure 5 (right). Do not
remove the lifting sling around the stored-energy hous-
ing, as the operator is top-heavy and must be adequately
supported until it is attached to the Circuit-Switcher.
Remove the skid and bracing which runs the length of the
operator, stored-energy housing, and operator support
tube. Also remove the protective cover atop the operator
support tube, as well as the protective covers on the oper-
ator enclosure louvers.
Step 9
Reposition the lifting sling around the front of the stored-
energy housing and wrap another lifting sling around the
back of the stored-energy housing, as shown in Figure 6.
Make certain that the operator door faces the same way
as the switch-position indicator on the cross base. Then
carefully hoist the operator into place. Be careful not to
damage the uni-ball coupling on the operator connecting
link during hoisting and attachment of the operator.
Attach the operator support tube mounting plate to the
underside of the cross base using four ¹⁄₂—131¹⁄₄ hex-
head galvanized steel cap screws, flat washers, and self-
locking hex nuts. Tighten all four screws securely.

ping skid for ease in handling.) Then attach four suitable
lifting slings (10 to 12 feet long for Circuit-Switchers rated
161 kV, 12 to 14 feet long for Circuit-Switchers rated 230
kV) to the lifting angles.
Make certain that the rigging does not stress the inter-
rupter, transition box, or disconnect. Unbolt the base
from the skid. Raise the pole-unit a few feet, then remove
the two ¹⁄₂—131³⁄₄hex-head galvanized steel cap
screws, flat washers, and hex nuts which attach the ship-
ping bracket to the bottom of the pole-unit channel base.
Note: The insulated operating rod is under pressure;
removal of the two screws may result in the operating rod
quickly moving down approximately ³⁄₈ inch. Remove the
¹⁄₂-inch silicon-bronze pin and cotter pin from the insu-
lated operating rod and retain these for re-use in Step
16(d). Discard the shipping bracket and associated hard-
ware.
Remove the protective cover on the cross base at the

Step 16
Prepare the insulated operating rod of each pole-unit for
attachment to the interphase drive in the cross base as fol-
lows:
(a) Remove the six ⁵⁄₁₆—18³⁄₄hex-head stainless-steel
cap screws used to attach the access cover to the side
of the transition box. See Figure 8 (left). Remove the
cover and place it and the hardware on a clean sur-
face.
(b) Check that the transition lever is in the open position.
The lever should be turned fully counterclockwise.
See Figure 8 (right). If the lever is not in the open posi-
tion, complete the following steps:
Carefully turn the transition lever to this position. If
the transition lever cannot be freely rotated to its fully
counterclockwise position, misalignment of the inter-
phase drive is occurring in the cross base. Temporarily
swing the insulated operating rod end links up, away
from the interphase drive linkage lever, and again try

Step 19
Make certain that the insulating support column drive
lever at each pole-unit is turned completely in the blade-
closing direction. Connect the factory-adjusted inter-
phase pipe assembly to the center pole-unit insulating
support column drive lever using a ¹⁄₂-inch stainless-steel
pin, two galvanized steel spacers, and two stainless-steel
“X” washers furnished. See Figure 11. Then attach the
interphase pipe assembly to the two outboard pole-unit
insulating support column drive levers.
In the event that the interphase pipe assembly cannot
be connected to an outboard pole-unit insulating support
column drive lever, loosen the appropriate locknut at the
adjustable coupling and rotate the affected interphase
pipe section so that the connection can be made; then
tighten the locknut. See Figure 11.
Verify, at each outboard pole-unit insulating support
column, that the clearance between the rotating-spindle
closed-stop bolt and the bumper is ¹⁄₁₆ inch or less. See
Figure 12 (left). (At the center pole-unit insulating support
column, the closed-stop bolt must touch the bumper.) In
the event that the clearance between the closed-stop bolt
and the bumper exceeds ¹⁄₁₆ inch at either outboard pole-
unit insulating support column, remove the pin at the
appropriate insulating support column drive lever, loosen
the appropriate locknut at the adjustable coupling, and
rotate the affected interphase pipe section so that the
aforementioned clearance is attained. Then replaced the
pin and tighten the locknut. See Figure 11. Do not adjust
the closed-stop bolts.
Step 20
Attach the clevis end of the interphase drive link to the
longer of the bell-crank arms on the cross base, using a ¹⁄₂-
inch stainless-steel pin and cotter pin furnished. See
Figure 11.
Step 21
Attach the “C”-shaped clevis at the lower end of the verti-
cal operating-pipe assembly to the take-off shaft on the
rear of the operator, using a ⁵⁄₈-inch stainless-steel pin and
stainless-steel “X” washer furnished. See Figure 11 (inset).
Then attach the straight clevis at the upper end of the ver-
tical operating-pipe assembly to the shorter of the bell-
crank arms on the cross base, using a ⁵⁄₈-inch stainless-
steel pin and cotter pin furnished. See Figure 11. If neces-
sary, loosen the locknuts at the top and bottom of the ver-
tical operating pipe and rotate the pipe so that the
connection can be made; then tighten the locknuts.

Step 22
Use the manual charging handle furnished with the opera-
tor to check functioning of the low-speed power train, as
follows. Refer to Figure 16.
(a) Open the access shutter and place the manual charg-
ing handle on the manual charging shaft.
(b) Rotate the shaft, clockwise only, just to the point at
which the disconnect-blade tongue contacts clear
their respective jaw-contact fingers. See Figure 13.
With the disconnect blades maintained in the posi-
tion shown in Figure 13, check each blade to verify that
its centerline has not shifted left or right by more than
¹⁄₄ inch—as measured to the centerline of its respective
jaw contact. If any blade centerline has shifted by more
than ¹⁄₄ inch, loosen the leveling-screw locknuts
located under the associated jaw-contact support insu-
lator. See Figure 14. Adjust the locknuts as necessary
to shift the jaw-contact centerline to correspond to
that of the blade centerline, ±¹⁄₄ inch. Then tighten the
locknuts. To avoid changing the effective height of the
support insulator, do not adjust more than three of
the four sets of locknuts.
(c) Continue to rotate the shaft, clockwise only, until a
firm resistance is felt. At this point, the disconnect
blades should be open past 90 degrees. If the discon-
nect blades are not open past 90 degrees, loosen the
locknuts at the top and bottom of the vertical operat-
ing pipe and rotate the pipe clockwise (as viewed from
the top) to increase blade travel; then tighten the lock-
nuts. Now verify, at each pole-unit insulating support
column, that the rotating-spindle open-stop bolt does
not touch the bumper. See Figure 12 (right). If any
open-stop bolt does touch the bumper, loosen the
locknuts at the top and bottom of the vertical operat-
ing pipe and rotate the pipe counterclockwise (as
viewed from the top) to decrease blade travel; then
tighten the locknuts. Do not adjust the open-stop
bolts.
(d) Remove the manual charging handle from the manual
charging shaft.
Step 23
Attach the high-voltage conductors to their respective Cir-
cuit-Switcher terminal pads using flexible-conductor con-
nections. Observe the terminal-pad loading limits
specified on the catalog drawing.
Use the following procedure for attachment:
(a) Thoroughly wire-brush the current-transfer surfaces
of each connector and immediately apply a liberal
coating of Penetrox®A (available from Burndy Corpo-
ration) or other suitable aluminum connector com-
pound to the brushed surfaces.
(b) Wire-brush each Circuit-Switcher terminal pad and
apply a coating of Penetrox A. Then bolt the connec-
tors to the terminal pads.
(c) Prepare the conductors using established procedures
and clamp them in their respective connectors.
Step 24
Remove the container from each interrupter as follows:
(a) Remove and discard the ³⁄₈—16 zinc-plated serrated
hex nuts which run the length of the container.
(b) Remove and discard the ³⁄₈—16⁷⁄₈and two
³⁄₈—161zinc-plated hex-head cap screws and flat
washers which attach the upper container-half to the
coupling end casting of the interrupter. Also remove
and discard the ³⁄₈—16⁷⁄₈and two ³⁄₈—161zinc-
plated hex-head cap screws and flat washers which
attach the upper container-half to the indicator end
casting of the interrupter.
