摘要
近年来,随着起重机械在电气系统上的长足发展,起重机械电气系统的复杂化给予检验检测人员带来较多困惑,同时起重机械由于漏电而造成的安全事故也时有发生,此类事故又多与接地系统缺失或不完备有关。在起重机械电气系统中,最为基础,同时也是最为重要的部分是起重机械的接地系统,接地系统的安全设置,可以避免因为漏电所造成的操作人员触电事故。本文对起重机械接地系统进行完整分析,并对检验人员现场检验起重机械接地系统给出相关建议。
In recent years, the hoisting machinery have great developed in both the mechanical structure and electrical system. The crane electrical system is more and more complicated that brings more confusion to the inspector; meanwhile, safety accidents caused by electrical leakage in hoisting machinery have occurred sometimes, which is always related to the missing grounding system or incomplete grounding system, so the grounding system detection has attracted more and more attention.
