高压断路器开合空载架空线路的试验研究

Test and Research on Switching No-load Overhead Lines Using High Voltage Circuit Breaker

分析了开合空载架空线路时断口上恢复电压的变化及影响恢复电压的因素。在实验室建立了252kV及以下断路器开合空载架空线的试验线路,并对试验结果进行了分析。

In this paper,the recovery voltage a cross circuit breaker is analyzed,and factors influencing TRV are dis-cussed w hen switching no-load overhead lines using high voltage circuit breaker.Test fac ility on switching line-charg-ing current in the laboratory has been establishe d and the test results are discussed too.
