1.故障现象我为某厂一条YJLV22-6kV、3×35mm~2电缆进行耐压试验中,当B相升至Us/4(Us=25kV)时,泄漏电流已达1000μA。根据电力设备预防性试验规程(DL/T596—1996)规定:6/6kV及以下电缆的泄漏电流应小于10μA。因此,这条电缆
1. Symptom I am a factory for a YJLV22-6kV, 3 × 35mm ~ 2 cable pressure test, when the B phase rose to Us / 4 (Us = 25kV), the leakage current has reached 1000μA. According to the Preventive Testing Regulations for Power Equipment (DL / T596-1996), the leakage current of 6 / 6kV and below cables should be less than 10μA. So this cable
