不同接地型式下的剩余电流保护探讨

Study on Residual Current Protection in Grounding Forms

在工程设计中,为了防范不可预知的电气火灾事故,通常选择使用剩余电流保护电器,在不同的接地型式下,剩余电流监测要求又不尽相同。本文结合现行标准及规范,针对市政电气设计中常见的接地型式,对剩余电流保护进行了分析探讨。

In engineering design,in order to prevent unpredictable electric fire,residual current-operated protective devices should be selected.However,monitoring requirements of residual current are different in different grounding forms.This paper combines current standards and norms,and analyzes residual current protection in common grounding forms of municipal electrical design.
