arcing earth meaning in English
电弧接地
Examples
- In the 3 ~ 35kv power supply system of our country , the large part is the not solidly earthed neutral system . when the single - phase earthed phenomena happens in this system , this electric power network can run with failure . and in this way the operated cost can reduce greadty . and at the same time the power supply systemic dependability can be improved . but when the single - phase earthed current is large , this electric power system can engender easily arc earthed overvoltage and interphase short circuit by this means
在我国10 35kv供电系统中，主要为中性点非直接接地系统，这种系统在发生单相接地时，电网仍可带故障运行，这样可以大大降低运行成本，提高供电系统的可靠性，但这种供电方式在单相接地电容电流较大时容易产生弧光接地过电压和相间短路，给供电设备造成了极大的危害。
