3.2.2 NDM2E 控制器控制面板各部分功能 Functions of each part in control panel of NDM2 controller
3.2.2.1 测试端口 Test port
“TEST”端口,NDM2E 专用测试仪器通过该端口与断路器控制器相连,进行测试及调试操作。此项操作应由
专业技术人员负责。
Through this “TEST”terminal, special tester for NDM2E is connected to the breaker’s controller
to conduct testing and debugging, etc. Such operations shall be completed by professional
technical personnel.
3.2.2.2 整定电流、整定时间、脱扣等级等调节旋钮 Adjusting knob for setting current 、setting time
and tripping rating
可通过电流、时间、脱扣等级旋钮的调节,选择适当的组合以达到保护线路、保护设备的作用,此项操作
应由专业技术人员负责。
Suitable combinations of current tripping rating and time are adjusted by this knob, so as to
protect circuits and devices. This operation should be done by specialized technical personnel.
注:1.TR 表示当实际电流为 IR 整定值的 2倍时,断路器动作时间。
Notes: 1. TR indicates the operating time of the breaker when actual current is twice of IR setting.
如:当 IR 整定为 250A、TR 整定为 100s 时,当主回路电流为 2×250A 时,断路器将持续 100s 时后
断开主回路。动作时间精度为±10%。在过载电流下,断路器断开主回路的时间遵循以下公式:
t=(2×Ir /I)2×Tr (其中 I表示过载情况下,主回路实际电流值)
E.g.: when IR and TR are set as 250A and 100s respectively, when the current in main circuit
reaches 2×250A, the breaker will disconnect the main circuit after lasting for 100s. The time
precision of action is ±10%. Under the overcurrent, the time that the breaker disconnects the
main circuit shall follow the following format:
t= (2*Ir/I) 2*Tr (Of which, I stands for the actual current in the main circuit under overcurrent.)
2. T 型、GT 型只能通过电脑上位机通讯软件调整整定值。
2. The setting values of T type and GT type breakers can only be adjusted through communication
software of the upper computer.
3. 电动机保护型面板,(2)与(3)整定是与其他类型的控制器的整定方法不同,两旋钮相加后的值作为
最后整定的值,若相加的和超过 In,则直接按 1倍的 In 来计算。
3.The motor protection type panel ,(2) and (3) settings are not the same as those of other types
of controllers. The values of the two buttons are added as the final setting value. If the sum
is more than In, Then directly by 1 times the In to calculate。
4. 电动机保护型断路器,如在脱扣等级规定的时间范围内,若累积的能量超过(7.2×Ir)2×Class,则提前
脱扣,若小于前面约定的值,且至脱扣等级时间到时,电流仍未降至 1.5 Ir 以下,则在脱扣等级规定的
时间到时,立即脱扣;在脱扣等级时间外,断路器脱扣的动作时间按公式 t=(7.2×Ir /I)2×Class 计算。

4. If the accumulated energy exceeds (7.2 ×Ir) 2 ×Class for a period of time specified in the
tripping rating, the motor-protective circuit-breaker shall be tripped in advance. If it is less
than the value specified in the previous paragraph and the time until the tripping time.The current
is not reduced to 1.5 Ir or less, then the time specified in the tripping rating to the time,
immediately tripping; outside the tripping time, the circuit breaker tripping time according
to the formula t = (7.2 ×Ir / I ) 2 x Class。
5. 电流不平衡率选择 OFF 时,控制器同时也关闭了断相保护功能,电流不平衡率的计算是,三相电流的
最大值与三相电流最小值的差值,与三相电流的平均值之间的比值,即为三相电流的不平衡率。
5. When the current unbalance rate is OFF, the controller also shuts off the phase protection
function. The calculation of the current unbalance rate is the difference between the maximum
value of the three-phase current and the minimum value of the three-phase current and the average
value of the three-phase current between three-phase current unbalance。
6. 短路短延时功能,在脱扣等级规定的时间内是关闭的,在脱扣等级规定的时间过后,短路短延时功能
才被打开。
6. Short-circuit Short delay function, which is switched off within the time specified in the
tripping rating , after the time specified in the tripping rating has elapsed, the short-circuit
short delay function is switched on。
3.2.2.3 指示灯 Indicator light
(1)预报警指示灯 Pre-alarm light
预报警指示灯黄灯闪亮时,表示实际电流超过了预报警电流 Ip 的整定值,经一定时间后黄灯将由闪亮转
为恒亮。
Flashes of pre-alarm indicator light indicate that actual current has exceeded setting value
for pre-alarm current Ip. After certain duration, the flashes will turn into constant
illumination.
(2)过载指示灯 Overload light
过载指示红灯恒亮时,表示实际电流超过了过载长延时整定电流值 Ir 的1.15 倍,处于过载状态,并经一
定的时间后断路器将断开。
Constant light of overload indicator indicates that actual current is more than 1.5 times of
overload long-time delay current setting IR. The breaker will break the circuit after certain
duration.
(3)电源指示灯 Power light
电源指示灯,在控制器得电后,开始闪烁,闪烁频率约为 1Hz,表明当前控制器处于有电状态,也可以表
明控制器处于正常工作状态。
When the controller is powered on, the power indicator light starts flashing. The flashing
frequency is about 1Hz, indicating that the controller is in the active state. It also indicates
that the controller is in the normal working state.
3.2.3 NDM2E 控制器通讯功能 Communication function of NDM2E controller
NDM2E 通讯功能通过外挂式通讯模块来实现“四遥”功能。该通讯模块可将断路器的相关信息经现场总线传
至上位机,上位机通过通讯模块下发指令操作电动操作机构,从而控制断路器的合、分。
The communication function of NDM2E can achieve “Four-remoteness”functions through the external
hanging communication modules. The communication module can transfer relevant information of
the breaker to upper computer through on-site bus, and then the upper computer can use the
instructions released by the communication module to operate the motor-operated mechanism, and
achieve closing and opening of the control breaker.
通讯模块上传的信息包括:Information uploaded by the communication module includes:
·断路器设备代码;Equipment code of the breaker;
·断路器各参数设定值;Setting values of the breaker’s parameters;
·断路器的合、分状态;Closing and opening state of the breaker;

灯点亮。如连接不正常则请用鼠标点击软件界面的“断开连接”按键后重新设置好配套参数或检查接线是
否正确后再次连接,直到通讯连接正常。
Run "MCCB communication system.exe" software provided by Shanghai Nader Electrical Co., Ltd. (see
Fig.6) and set the parameters: COM port, baud rate, sub-station address (The parameters include baud rate and
sub-station address need to be the same with the connected breaker. Factory default settings: baud rate 9600 and
sub-station address 3). After setting the parameters, click the "Connect" button on software interface, if
communication link is working correctly (see Fig. 7), communication status light will be on; if not, please click
the "Disconnect" button on software interface, reset parameters and connect again after you make sure wiring is
correct until the communication link is working correctly.
