浅析35kV电力系统单相接地故障及其处理

Analysis of Single-phase Fault in 35kv Power System and Its Treatment

35k V系统因为线网复杂,运行环境相对不好,单相接地故障较为多发,但在小电流接地系统,可以带故障短时间运行,但必须在规定的时间内排除,否则,会引发更大的事故。本文从接地故障运行特点、接地故障现象及其识别、接地故障的处理等方面对此做了深入探析,具有较强的工程实践意义。

As the complexity of the wire mesh, the running environment, the single phase grounding fault is more in the 35 k V system, it can run with fault in a short time if it is in the small current grounding system, but it must be excluded within the specified time, otherwise, it will lead to more a major accident.This paper discussed the operational features, phenomena and identification and ground fault treatment, it has strong engineering practice significance.
