电梯接地检验方法探讨

Discussion on Inspect Method of Elevator Grounding

本文首先根据检规论证了电梯供电电源必须采用TN-S、TN-C-S的接地型式,并提供了如何实施验证的检验方法,接着依据GB 7588—2003,提出了电梯电气安全回路、门联锁回路等接地的检验要求与检验方法,最后根据GB 16895.21—2011,指出一种电气安全装置不需要设置接地的情形。

This paper firstly proofs that the grounding typeof power supply for elevator must beTN-S orTNC- S , provides how to implement the validation test;and thenputs forward grounding inspection requirements and testing methods of the elevator electrical safety circuit anddoor interlock circuiton the basis of GB 7588一2003. At last, according to GB 16895.21一2011, a kind of electrical safety devices do not need to set up groundingis pointed out.
