摘要
剩余电流动作保护装置(RCD)广泛应用于电击防护和电气火灾报警,但由于选用和安装不当,运行过程中会发生不动作和误动作。针对这一现状,在分析了剩余电流与对地泄漏电流、漏电电流和剩余电流与零序电流等相关术语的基础上,总结了常见RCD安装不当的情况,并提出了对应的解决方案或措施。
Residual current operated protective devices have been widely applied in protection of lighting strike and prevention of electrical fires.However,there will be malfunctions in practical applications due to inappropriate selection and installation.On the basis of identifying residual current,earth leakage current and zero sequence current,the common cases of inappropriately installing residual current operated protective devices are summarized.Furthermore,the solutions to deal with the problems are proposed.
