B型剩余电流保护在新能源发电和电动汽车中的应用
|
摘要
面对日益复杂的剩余电流形式以及需要对剩余电流实时监测的地方增多,传统剩余电流保护显得力不从心。B型剩余电流保护因其可以检测复杂剩余电流并且带有实时监测功能,已经运用到一些特定的保护领域中。文章分别阐述了B型剩余电流保护在三级剩余电流保护、电动汽车充电桩剩余电流保护和光伏发电系统剩余电流保护中的应用,论证了B型剩余电流保护推广的必要性和重要性。
Facing the increasing complexity of residual current forms and the increasing need for real-time monitoring of residual current,the traditional residual current protection is unable to deal with.Type B residual current protection has been applied to some specific protection fields because it can detect complex residual current and has real-time monitoring function.This paper describes the applications of type B residual current protection in three-stage residual current protection,electric vehicle charging pile residual current protection and photovoltaic power system residual current protection.And the necessity and importance of popularizing B-type residual current protection is demonstrated.
