MNS低压抽屉柜发生储能故障怎么办？这个问题是不少用户会问到的，为了让大家能够在之后的日子里顺利正常的使用，下面小编为您解答下这个问题。

What should I do if there is an energy storage failure in the MNS low-voltage drawer cabinet? This is a question that many users will ask. In order to enable you to use it smoothly and normally in the days to come, let's answer this question for you.

1.行程开关调节不当

1. Improper adjustment of travel 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 travel switch is a limit switch that controls the energy storage position of the motor. Cut off the power supply of the motor when the energy storage of the motor is in place. If the limit is too high, the mechanism energy storage is full. The fault phenomenon is that the motor does not stop when idling and the energy storage indicator does not light up. Only by opening the control switch (HK) can the motor stop. When the limit adjustment is too low, the motor stops in advance before the energy storage is full. The switch cannot be closed because the energy storage is not in place. The way to adjust the limit is to slowly store energy manually to find the correct position 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 burnt, there will be peculiar smell, smoke, fuse blowing and other phenomena. If there is voltage at both ends of the motor, the motor will not rotate. The carbon brush may fall off or be seriously worn. The way to determine whether the motor is faulty is to measure the voltage and resistance at both ends of the motor or replace it with other good motors.

3.控制开关故障或电路开路

3. Control switch fault or open circuit

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。

The switch cabinet believes that when the control switch is damaged and the circuit cannot be closed and the control circuit is disconnected and causes an open circuit, the fault manifestations are that the motor does not rotate and there is no voltage at both ends of the motor. The search method is to measure the voltage or resistance with a multimeter. The voltage measurement method is to adjust the multimeter to the voltage range when the control circuit is powered on. If there is voltage (except for the step-down element), there is an open circuit between the two measured points. Pay attention to the on-off of the bypass when using the resistance measurement method. If there is a bypass parallel circuit, disconnect one end of the measured line.
