  电容器在工作中电流突然增大的缘由,是电容器的介质损耗增大、漏电增加所形成的。电力电容器在运行过程中,电流会突然增大是什么原因引起的呢?

  The reason for the sudden increase of current in the operation of capacitor is the increase of dielectric loss and leakage of capacitor.What is the reason for the sudden increase of current in the operation of power capacitor?

  If the current of the power capacitor in operation suddenly increases, the power should be cut off first to check the current and leakage of the capacitor.

  检查之后如果各项都正常,工作中的电容器电流突然增大的原因是工作的电力系统内的负载新增了有高次谐波发作的设备,比如电弧炉、电镀整流器、变频调速或直流调速设备等。

  After inspection, if all items are normal, the reason for the sudden increase of capacitor current in operation is that the load in the working power system adds equipment with high-order harmonic generation, such as electric arc furnace, electroplating rectifier, frequency conversion speed regulation or DC speed regulation equipment.

  另外一种情况是在同一10kV电力配电系统的其它用户新增了有高次谐波发作的设备构成系统烦扰影响所形成的。

  Another case is that other users in the same 10kV power distribution system add equipment with high-order harmonic attack, which is caused by system disturbance.

  山东红宝电子认为,电力电容器在正常运行过程中,工作人员应当加强巡视,包括监督工作电流、查询电容温度,并且时常观察电容器外形能否出现漏油、鼓肚子现象。

  Shandong Hongbao electronics believes that in the normal operation of power capacitors, the staff should strengthen inspection, including supervision of working current, inquiry of capacitor temperature, and often observe whether the appearance of capacitor leakage, bulging phenomenon.

  一旦发现问题要及时停止工作,并找专业人员前来检查并修复或者替换。

  Once the problem is found, stop working in time, and find professionals to check and repair or replace.
