摘要
现如今变电站内各电压等级的断路器普遍配置了保护装置防跳或开关机构防跳保护方式,两种防跳回路均能独立完成防跳功能。通过广东梅州某110 kV变电站一起10 kV电容器保护防跳与机构防跳同时使用的缺陷处理情况的概述,分析两种防跳回路同时使用的弊端和机构防跳回路的改进措施。
At present,the circuit breakers of various voltage levels in substations are generally equipped with anti tripping protection devices or switch mechanisms,and the two anti tripping circuits can independently complete the anti tripping function. Based on the summary of the defect treatment of a 10 KV capacitor protection anti trip and mechanism anti trip in a 110 kV Substation in Meizhou,Guangdong Province,this paper analyzes the disadvantages of two anti trip circuits and the improvement measures of mechanism anti trip circuit.
