摘要
针对工程设计中对一些重要负荷采取过负荷保护动作于报警不切断电源的做法,作者通过现行国家标准规范、IEC标准对过负荷的定义、不设置过负荷保护及"过负荷保护可以省略"等相关规定的学习、分析,结合用电设备实际工作特征,就"过负荷保护可以省略"规定的理解和应用提出一些观点,供业内同行参考。
In view of overload protection action in alarm and not cut off power supply applied to some key loads during engineering design, the author, based on study and analysis on overload definition and provisions, e.g., overload protection is not set and can be omitted, in current national standard specification and IEC standards and in combination with the actual operating features of power equipments, gives ideas on understanding and application of the provision that overload protection can be omitted for reference in the same industry.
