晶闸管过零关断零电压介质恢复阻断影响因素的分析
|
摘要
为了分析晶闸管换流过零的暂态关断恢复特性影响因素,设计了晶闸管强迫过零关断后零电压恢复的试验电路。通过试验系统地研究了影响晶闸管暂态恢复时间的两个重要因素,并且就通流大小、通流时间对晶闸管恢复时间特性具体产生的影响做了详细的分析。分析结果表明,晶闸管通流幅值的增大与通流时间的增长均会对其恢复时间产生不利的影响。
In arder to analyze the factors of transient zero through the thyristor turn-off characteristics of recovery,this paper presented the experimental circuit of thyristor forced through zero-zero-voltage shutdown recovery to study the effects of the thyristor transient recovery time.In respect of factors(the size of the throughflow,flow time) it analyzed the thyristor recovery time characteristics and the impact.The analyais results show that the thyristor through-flow growth and an increase in the magnitude of flow-through time will adversely affect their recovery time.
