3.2.2 NDM3E 控制器控制面板各部分功能 Functions of each part in control panel of NDM3E controller
3.2.2.1 测试端口 Test port
“TEST”端口,NDM3E 专用测试仪通过该端口与控制器相连,进行测试及调试等操作。
Through this “TEST”terminal, special tester for NDM3E is connected to the controller to
conduct testing and debugging etc.
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。
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)
2. T 型、GT 型只能通过电脑上位机通讯软件调整整定值。
3. 电动机保护型面板,(2)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。
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。
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。
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。
Notes: 1.TRindicates the operating time of the breaker when actual current is twice of IRsetting.
E.g.: when IRand TRare 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. The setting values of T type and GT type breakers can only be adjusted through
communication software of the upper computer.
3. The motor protection type panel ,(2) 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. 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 IRor 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 ) 2x Class。
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. 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,经特定时间后黄灯将由
闪亮转为恒亮。
(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。
(1)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)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.
3.2.2.4 NDM3E 控制器通讯功能 Communication function of NDM3E controller
NDM3E 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 NDM3E 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;

3.2.2.5 NDM3E 专用测试仪 Special tester for NDM3E
使用 NDM3E 专用测试仪器通过控制器上的“TEST”端口与断路器本体相连。可对控制器进行故障
测定、数据记录、脱扣试验等操作。
When connecting “TEST”terminal on the controller and breaker by using special tester for
NDM3E. The tester can be used for testing failures of the controller, recording data, and tripping tests
etc.
3.2.2.6 NDM3E 控制器过载报警不脱扣功能 Alarm without trip for overload of NDM3E controller
当NDM3E 控制器上的 TR档位设置为“OFF”时,断路器具有过载报警不脱扣功能。即在线路过负
荷的情况下,断路器不跳闸仅输出过负荷信号。保障了供电的连续性,满足 GB 50054 中第 4.3.3 条“突
然断电比过负载造成的损失更大的线路,其过负载保护应作用于信号而不应作用于切断电路”的要求。
该功能可有效替代热继电器报警,节约成本。
When TR shift on the NDM3E is set as “OFF”, the breaker has the function of alarm without
tripping for overload, namely in the case of overload on the circuit, the breaker only outputs overload
signals with tripping, which can ensure continuity of powering supply, meeting requirements of
Section 4.3.3 in GB 50054: In the circuit where the sudden disconnect of power supply can bring
larger losses than overload, and the overload protection shall act on the signals other than
disconnecting the circuit. The function can effectively substitute thermo-relay alarm for saving costs.
