摘要

真空断路器在分断过程中的再次跳闸会造成过电压,加剧高压设备的绝缘劣化。为了解决这一问题,对真空断路器的老化试验方法和再燃特性进行了研究。建立了40.5kV真空断路器耐压试验台,研究了真空断路器触头间距、回路电流和涌流对再燃次数、击穿电压波前陡度和击穿持续时间的影响。随着真空断路器触头间距的增加,真空断路器分断过程中的再燃次数减少,重复击穿电弧的持续时间增加。随着测试系统回路电流的增加,真空断路器分断过程中的重燃次数、击穿电压的波前陡度和重燃电弧的持续时间都增加了。随着真空断路器合闸过程中涌入电流幅值的增加,真空断路器分断过程中的再燃次数和重复击穿电弧的持续时间增加。研究结果为40.5kV真空断路器的预防性试验和耐压试验的优化提供了理论依据和数据支持。

Restrike characteristics of vacuum circuit breaker in its opening process under DC voltage

Restrike characteristics of vacuum circuit breaker in its opening process under DC voltage

The restrike of vacuum circuit breaker during the breaking process causes overvoltage and intensifies the insulation deterioration of high-voltage equipment. To solve this problem, the vacuum breaker aging test method and the restrike characteristics are researched. A withstand voltage test platform of 40.5-kV vacuum circuit breaker was established to obtain the effects of the contact spacing and loop and inrush currents of vacuum circuit breaker on the number of restrike, the wavefront steepness of the breakdown voltage, and the breakdown duration. The number of restrike during the breaking of vacuum circuit breaker decreased and the duration of the repeated-breakdown arc increased with the increased contact spacing of vacuum circuit breaker. As the loop current of the test system increased, the number of restrike during the breaking of vacuum circuit breaker, the wavefront steepness of the breakdown voltage, and the duration of the restrike arc increased. As the inrush current amplitude increased during the closing of vacuum circuit breaker, the number of restrike and the duration of the repeated-breakdown arc during the breaking of vacuum circuit breaker increased. The results provide a theoretical basis and data support for the preventive test of 40.5-kV vacuum circuit breaker and the optimization of the withstand voltage test.
