How to analyze the energy storage failure of high voltage switchgear

1.行程开关调节不当

Improper adjustment of 1. stroke switch

行程开关是控制电机储能位置的限位开关。当电机储能到位时将电机电源切断。如果限位过高时,机构储能已满。故障现象是:电机空转不停机、储能指示灯不亮。只有打开控制开关(HK)才能使电机停止。限位调节过低时,电机储能未满提前停机。由于储能不到位开关不能合闸。调节限位的方法是手动慢慢储能找到正确位置,并且紧固。

The stroke switch is the limit switch that controls the position of the energy storage of the motor. The motor power is cut off when the motor is stored in place. If the limit is too high, the storage capacity of the mechanism is full. The failure phenomenon is: the motor is not shut down and the energy storage indicator is not bright. Only by opening the control switch (HK) can the motor be stopped. When the limit adjustment is too low, the energy storage of the motor is not full ahead of time. The switch can not be closed because the storage energy is not in place. The way to adjust the limit is to manually store the right position by hand and tighten it.

2.电机故障

2. motor fault

如果电机绕组烧毁,将有异味、冒烟、保险熔断等现象发生。如果电机两端有电压,电机不转。可能是碳刷脱落或磨损严重等故障。判断是否是电机故障的方法有测量电机两端电压、电阻或用其它好的电机替换进行检查。

If the motor winding is burned down, there will be strange smell, smoke, insurance fuse and other phenomena. If there is a voltage at both ends of the motor, the motor does not turn. It may be the failure of the brush to fall off or serious wear and tear. The method of judging whether the motor is malfunction is to measure the voltage and resistance of the motor at both ends of the motor or to replace the motor with other good motors.

3.控制开关故障或电路开路

3. control switch fault or circuit opening

贵州开关柜认为控制开关损坏使电路不能闭合及控制回路断线造成开路时,故障表现形式都是电机不转、电机两端没有电压。查找方法是用万用表测量电压或电阻。测量电压法是控制电路通电情况下,万用表调到电压档,如果有电压(降压元件除外)被测两点间有开路点。用测量电阻法应当注意旁路的通断,如果有旁路并联电路,应将被测线路一端断开。

Guizhou switchgear thinks that the damage of the control switch causes the circuit not to be closed and the control circuit break, which leads to the failure of the motor. The lookup method is to measure the voltage or resistance by a multimeter. When the measurement voltage method is the control circuit, the multimeter is tuned to the voltage gear. If there is a voltage (excluding the antihypertensive element), there is an open point between the measured two points. The method of measuring resistance should be paid attention to the bypass of the bypass. If there is a bypass circuit, one end of the measured line should be disconnected.
