摘要
对一起220kV断路器跳闸线圈的烧毁原因进行了分析,并提出了对目前常用的跳合闸回路进行改造的建议。改造后的跳合闸回路不但能够有效避免跳合闸线圈的烧毁,而且能对相应的跳合闸机械结构及辅助触点的完好性进行监测。
In this paper, the burning reason of 220kV breaker trip coil is analyzed in detail and suggestion of improving traditional trip circuit and closing circuit is made. The improving circuit can not only avoid burning of breaker trip coil or closing coil, but also monitor readiness of trip or closing mechanical structure and auxiliary contact.
