相信大家对精密配电柜有所了解,但它常遇到的问题你知道的多少?接下来杭州铭伟斯电气PK10就给大家讲解精密配电柜常见问题与原因分析,有需要的朋友可要好好的学习。

  精密配电柜之断路器不能合闸:具有以下几点:

  1、欠压线圈不工作(电压正常)。解决办法:更换欠压线圈

  2、按下合闸按钮,合闸线圈得电不工作。解决办法:更换欠压线圈 

  3、合闸按钮接触不良。解决办法:更换合闸按钮

  4、控制回路熔芯烧坏。解决办法:确认控制回路正常无短路后更换熔芯

  5、断路器未储能。解决办法:检查电动机控制电源电压必须≥ 85% 

  6、合闸电磁铁控制电源电电压小于85% 。解决办法:合闸电磁铁电源电压必须≥ 85%

  7、合闸电磁铁已损坏.。解决办法:更换合闸电磁铁

  8、抽屉式断路器二次回路接触不良。解决办法:把抽屉式断路器摇出后,重新摇到“接通”位置。检查二次回路是否连接可靠

I'm sure you know something about the precision switchboard, but how much do you know about the problems it often encounters? The next small editor to explain the precision distribution cabinet common problems and need friends to study well。
The breaker of the precision power distribution cabinet can not be closed: It has the following points:
1, undervoltage coil does not work(the voltage is normal). Solution: Replacement of understressed coil
2, press the closing button, the closing coil does not work. Solution: Replacement of understressed coil
3, close the button contact poor. Solution: Replace Close Button
4, control circuit core burn. Solution: Replace the core after confirming that the control loop is normal and does not short-circuit
5, circuit breakers do not store energy. Solution: Check the motor to control the power supply voltage must ≥ 85 %
6, closed electromagnet control power voltage is less than 85 %. Solution: closed electromagnet power supply voltage must ≥ 85 %
The closed electromagnet has been damaged。 And 。。。 Solution: Replace Close Electromagnet
8, drawer type circuit breaker secondary circuit contact poor. The solution: shake the drawer circuit breaker out and shake it back to the "connected" position. Check that the secondary loop is connected reliably
