此方法是在不使用仪器的情况下,用最短的时间,走最短的路程,将漏电部位压缩到最小范围。一、正线漏电用试灯(8W/50V)一端接在整流箱中D-端子,一端接在电容C_5、C_6的接地线上,若灯亮,说明正线漏电。查找方法如下: (1)将乘务室内配电盘上的全部负载闸刀断开,有两种可能:①试灯灭。车上负载正线漏电,把闸刀一个一个地合上去,当合到那一个闸刀,试灯亮了,就是那一路负载漏电。②试灯仍亮。说明不是车上负载漏电。
This method is in the case of not using the instrument, with the shortest possible time, take the shortest distance, the leakage area is compressed to a minimum range. First, the main line leakage test lamp (8W / 50V) one end connected to the rectifier box D-terminal, one end connected to the capacitor C_5, C_6 ground wire, if the light, indicating the main line leakage. Find ways are as follows: (1) The crew switch off all load switchgear indoor distribution panel, there are two possibilities: ① test light off. Car load on the line leakage, the knife one by one to go together, when combined to that one knife, test lights, that way load leakage. ② test light is still lit. Description is not the car load leakage.
