摘要
概括了断路器关合短路电流时由预燃弧阶段开始的物理过程,对比了触发火花间隙和真空触发开关用作快速关合装置时的触发特性,提出了一种在全电压条件下进行合成关合的试验回路。对全电压条件下进行合成关合试验时,外施电压相位控制、外施电压与关合电流相位差要求进行了分析,并提出了相应的控制策略和解决方法:对影响控制准确度的主要因素进行了分析。
Beginning from pre-arcing between the electrodes during breaker making the short-circuit process, this physical process is discussed. The trigger characteristics of triggered spark gaps and of triggered vacuum switch are compared, and a synthetic making circuit at full-rated voltage is presented. The control of the phase of applied voltage, and the demand of the phase difference between applied voltage and making current in synthetic making test under full-rated voltage are provided. The strategy and the main factors effecting controlling accuracy are also analyzed.
