弹簧机构分闸锁扣系统对高压断路器分闸时间影响研究

Gaoya dianqi
高压断路器是电力系统中重要的保护和控制设备。高压断路器可以采用弹簧机构来执行分闸动作，断路器分闸时间是指处于合闸位置的断路器，从弹簧机构分闸脱扣器带电时刻到所有各极弧触头分离时刻的时间间隔。弹簧机构分闸脱扣器动作时间在断路器分闸时间中占比50%左右，通过改变弹簧机构分闸锁扣器动作时间是调整断路器分闸时间关键因素。为有效调整断路器分闸时间，文中根据断路器分闸动作的原理，以高压断路器用弹簧机构分闸锁扣系统为研究对象，采用机械动力学仿真计算分析方法，分析分闸锁扣系统对断路器分闸时间的影响 ...

新型10 35千伏少油断路器的进展及论证

Gaoya dianqi, 1960
高压电器研究所、上海永新电工器材厂,华通开关厂都在高压开关专业会议上汇报了10千伏新型配电用少油断路器的试验研究工作的进行情况。永新厂的10千伏新型断路器曾于2月份在高压电器研究所进行了断流容量试验,并开断了300兆伏安的短路电流。高压电器研究所向大会提出了机械油吹灭弧装置的研究报告(见本期第15页),目前该所试制的新型断路器已开断了相当于350兆伏安的短路电流。会议认为正在研究的新结构无论在性能上、经济上、都较少内1—10型(仿—133)少油断路器来得优越,它有很大的发展前途。
