電容器在工作中電流突然增大的緣由，是電容器的介質(zhì)損耗增大、漏電增加所形成的。電力電容器在運(yùn)行過程中，電流會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.

　　檢查之后如果各項(xiàng)都正常，工作中的電容器電流突然增大的原因是工作的電力系統(tǒng)內(nèi)的負(fù)載新增了有高次諧波發(fā)作的設(shè)備，比如電弧爐、電鍍整流器、變頻調(diào)速或直流調(diào)速設(shè)備等。

　　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.

　　另外一種情況是在同一10kV電力配電系統(tǒng)的其它用戶新增了有高次諧波發(fā)作的設(shè)備構(gòu)成系統(tǒng)煩擾影響所形成的。

　　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.

　　山東紅寶電子認(rèn)為，電力電容器在正常運(yùn)行過程中，工作人員應(yīng)當(dāng)加強(qiáng)巡視，包括監(jiān)督工作電流、查詢電容溫度，并且時(shí)常觀察電容器外形能否出現(xiàn)漏油、鼓肚子現(xiàn)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.

　　一旦發(fā)現(xiàn)問題要及時(shí)停止工作，并找專業(yè)人員前來檢查并修復(fù)或者替換。

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