很多设备在运行过程中都免不了要出现故障，当配电柜出现故障的时候，能否可以及时有效的处理就是对做运维技术的考验了。下面就来简单了解一番吧。

Many equipment will inevitably fail during operation. When the power distribution cabinet fails, whether it can be handled in time and effectively is the test of operation and maintenance technology. Now let's have a brief look.

（1）操作不当。

(1) Improper operation.

（2）合闸电源消失。

(2) The closing power supply disappears.

（3）控制回路断线。

(3) The control circuit is disconnected.

（4）转换开关接触不良。

(4) The change-over switch is in poor contact.

（5）合闸线圈断线。合闸接触器线圈断线。

(5) The closing coil is disconnected. The coil of closing contactor is disconnected.

（6）辅助触点接触不良。

(6) Poor contact of auxiliary contact.

（7）其它机械方面故障,如传动机构连杆脱落、合闸铁芯卡涩,断路器分闸后机构没有复位等。

(7) Other mechanical faults, such as the falling off of the connecting rod of the transmission mechanism, the jamming of the closing iron core, and the failure of the mechanism to reset after the opening of the circuit breaker.

处理方法：

Treatment method:

（1）在绿灯亮的情况下,再合一次闸,如果合上,说明是转换开关没合到位,属于操作不当。

(1) When the green light is on, close the switch again. If it is closed, it means that the change-over switch is not closed in place, which belongs to improper operation.

（2）如果绿灯亮,接触器动作,应该检查合闸电源是否正常,如电源开关没投、合闸熔断器熔断等原因并处理。检查熔断器是否熔断的方法有两种:一种为带电检查,一种为取下后用欧姆档检查。

(2) If the green light is on and the contactor acts, check whether the closing power supply is normal, such as the failure of the power switch and the fusing of the closing fuse, and deal with it. There are two methods to check whether the fuse is fused: one is live inspection, and the other is to check with Ohm gear after removal.

（3）如果绿灯不亮,那么首先检查控制熔断器和小开关是否熔断或者跳闸。若果发现问题,应及时更换。

(3) If the green light is not on, first check whether the control fuse and small switch are fused or tripped. If any problem is found, it should be replaced in time.

（4）辅助触点接触不良,绿灯不亮,打开机构盖,检查合闸回路辅助触点,调整小拉杆到合格位置。什么位置算合格?

(4) The auxiliary contact is poor and the green light is not on. Open the mechanism cover, check the auxiliary contact of the closing circuit, and adjust the small pull rod to the qualified position. What position is qualified?

（5）合闸接触器线圈断线,或者接点卡劲。更换接触器或者拆下检修。

(5) The coil of the closing contactor is disconnected, or the contact is jammed. Replace the contactor or remove it for maintenance.

（6）转换开关接触不良,用短路线将5-8接点短路后能合闸,说明接点接触不良,拆检修或者更换。

(6) If the change-over switch has poor contact, it can be closed after short circuiting the 5-8 contact with a short circuit, which indicates that the contact has poor contact, and it should be removed for maintenance or replacement.

（7）打开机构盖，用手动合闸检查合闸顶杆是否能过托架2mm，如果不能说明合闸铁芯行程不够，应调整铁芯顶杆长度。

(7) Open the mechanism cover and check whether the closing ejector rod can pass the bracket by 2mm with manual closing. If it cannot be explained that the stroke of the closing iron core is not enough, the length of the iron core ejector rod should be adjusted.

（8）打开机构盖,检查机构在上一次分闸后是否回位。如果没有，应手动方法将其归位，再合闸。

(8) Open the mechanism cover and check whether the mechanism returns after the last opening. If not, it should be manually reset and reclosed.

（9） 山东电缆桥架厂家建议检查合闸电源电压是否满足不低于85%的额定电压。

(9) Shandong cable tray manufacturer suggests to check whether the closing power supply voltage meets the rated voltage of no less than 85%.
