1 Product description

This User Guide describes the Vacuum Circuit Breakers manufactured by Tavrida Electric.
Tavrida Electric circuit breakers are designed for rated voltages up to 24 kV.
Vacuum Circuit Breakers described in the current document can be used in various kinds of switchgear and
RMUs and are intended to perform switching operations in network rated and faulty modes.
The breakers are comprised of following main components:
Indoor Switching Module (ISM) - The air insulated ISM incorporates Tavrida Electric vacuum interrupters
with monostable magnetic actuators and solid dielectric insulating materials. No SF-6 or oil insulation is
used in the ISM;
Control Module (CM) - The CM is a microprocessor based controller that provides ISM operation,
protection and data logging functions;
Kits - The kits of components are used to provide circuit breaker application properties.
This guide contains information on switching operations, required check-ups and maintenance, as well as
service and disposal procedures. The purpose of the document is to provide necessary product information
for users providing installation, commissioning and utilizing installed equipment.

The present User Guide contains information necessary for the installation, commissioning and operation. It is
absolutely necessaryfor the proper use of the Vacuum Circuit Breakers to read the User Guide carefully before
starting and to adhere to the instructions and the relevant regulations. Tavrida Electric will not accept any
claims for damages caused by improper usage of the Vacuum Circuit Breakers. In case of special
configurations please contact Tavrida Electric prior of usage of the Vacuum Circuit Breakers.
1.4 Precautions
Check whether the installation position (distances, spatial separation, and the surroundings) is suitable
for the switching devices.
Installation, operation and maintenance shall only be carried out by trained and experienced personnel
who are familiar with the equipment and the electrical safety requirements.
During installation, commissioning, operation and maintenance of the equipment the relevant legal
regulations (such as DIN/VDE/IEC), accident prevention regulations and the connecting conditions of the
electric utilities shall be followed.
Take note that during operation of the Vacuum Circuit Breakers certain parts are subject to dangerous
voltage. Mechanical parts, also remote-controlled, can move quickly. Failure to comply may result in
death, severe personal injury or damage to equipment.
Pay attention to the hazard statements located throughout this User Guide.
The operating conditions of the vacuum circuit breakers shall comply with the technical data specified in
this User Guide.
Personnel installing, operating and maintaining the equipment shall be familiar with this User Guide and
its contents.
1.5 Warranty
Unless otherwise stated in the contract, the warranty period is stated in Standard warranty policy. If agreed to
otherwise, the contract conditions apply. No warranty is given in the case of …
a) … the warranty period having run out during the period of storage with the customer;
b) … the operating conditions, ambient conditions, transport and storage conditions have not been adhered
to according to the application description or the Installation and Operating Instructions;
c) … an unauthorized manipulation of the device has been carried out, such as opening the housing or
damaging the seal;
d) … the device has not been properly installed, such as incorrect connection of supply voltage of auxiliary
circuits.

3 Product handling

19
3.1 Transportation
The VCBs are transported in the original packing only. Any kind of transport and combinations thereof are
applicable. Transportation shall be provided in waterproof compartments. If air transport is used all products
shall be transported inside heated, pressurized compartments. The packed goods shall be handled in
accordance with the handling symbols. Loading procedures for VCB packaging shall be carried out only with
use of fork lifts, hoists or cranes. If possible the packaged VCB shall be placed on a pallet. During transportation
the VCB must not be subjected to sharp impacts or dropped.
3.2 Storage
If immediate installation is not possible, the VCB shall be stored in the original packing under the following
conditions:
the ISM is switched off;
desiccant must be placed in the packaging;
storage must be dry, well ventilated and the room temperature should be between - 25°C and + 55°C.
Average humidity measured over 1 year period shall not exceed 75% at 50ºC. If several VCBs are stacked a
maximum of two vertical layers are permitted
In case the storage term exceeds one year from the production date it is recommended to perform the procedu-
re of CM‘s electrolytic capacitor conditioning:
apply power to the CM for 20 seconds;
switch off the power supply and wait for 60 seconds;
repeat the above actions 2 times;
apply power to the CM continuously for 8 hours.
This procedure shall be performed annually during storage of the CM.
3.3 Unpacking and inspection
VCB unpacking and check
Before unpacking, check the carton for damage. Removal of the products from the original packaging must be
carried out with care and in accordance with lifting procedures. Every VCB component shall be checked for
completeness against the packing list included within the routine test certificate supplied with the CM and ISM.
These shall also be verified against the BOM list on the VCB packing list for VCB components and kits.
Unloading procedures for ISM shall be carried out only with use of hoists or cranes. Lifting gear must not be
attached to the support insulators; methods of lifting the ISM out of the carton shown below and must be strictly
followed.

Lifting of ISM15_HD_1
All items should be checked visually for:
mechanical damage, scratches, discoloration, corrosion;
damage to the seals Figure 3, Figure 5).
Any transport damage must be reported immediately to the carrier in writing. Damages shall be
photographically documented.
VCB packaging and scope of supply
The VCB are placed in cardboard boxes (Figure 18):
handling symbols label for transport and storage of the delivery unit (Figure 16);
labels for manufacturers and product information (Figure 19);
label for logistics data (Figure 17).
