摘要
超高压电网快速发展,同塔双回输电线逐步推广使用,断路器机构与自适应重合闸的配合必须重视。论述了同塔双回输电线自适应重合闸的基本策略,分析了某液压机构断路器的合闸回路及合闸低油压闭锁回路,提出了该断路器液压机构与自适应重合闸配合方面存在的问题,详细分析了自适应重合闸动作失败的原因,并提出了相关解决方案。
The cooperation of circuit breaker and adaptive recloser should be taken into consideration seriously due to the fast development of extra - high voltage power grid and the gradual promotion of double circuit lines on the same tower. The basic strategies of adaptive recloser in double circuit lines on the same tower are discussed, the closing circuit and the low oil pressure blocking circuit of circuit breaker of a hydraulic mechanism are analyzed, and the existing problems which may be caused by the cooperation of hydraulic mechanism of this kind breaker and adaptive recloser are proposed. The causes of adaptive reclosing failure are analyzed in detail, and the corresponding solutions are put forward.
