低压保护电器选择方法的探讨

Discussion on the selection methods of low voltage protection apparatus

以国家现行规范为基础,对低压保护电器的选择作了必要的分析,对其在实际工程应用中的设计及配置方法进行了论述和计算,另外对低压保护电器的分断能力及动作的灵敏性等也作了校验和总结,以确保低压配电系统设计安全可靠、经济合理。

Based on the existing national standards, this paper made necessary analysis on the selection of low voltage protection apparatus, dis cussed and calculated its design and configuration methods in practical engineering application, in addition, checked and summarized the break ing capacity and action sensitivity of low voltage protection apparatus, in order to ensure the design safe and reliable, economic and reasonable of low voltage distribution power system.
