摘要
针对常规继电保护装置在电弧光故障时存在保护选择性与速动性相互制约的不足,提出设置弧光保护的必要性,结合工程实例说明弧光保护系统的组成、设备配置,分析其逻辑原理,阐明设计中需注意的技术要点。
In view of the deficiency of mutual restriction between selectivity and speed of conventional relay protection device in arc fault,this paper emphasizes the necessity of setting arc protection,and illustrates the composition and equipment configuration of arc protection system,analyzes its logical principle,and expounds the technical points needing attention in design.
