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。
