| 摘 要： | 高压直流输电HVDC晶闸管换流阀的非周期触发试验是换流阀型式试验中的一项重要试验.对于完整的阀,通常采用并联电容器法进行试验.笔者比较了几个不同工程晶闸管换流阀的试验数据,探讨了晶闸管非周期触发试验中恢复期保护的几个问题.实验证明,晶闸管触发后恢复期内过高的du/dt或再次触发将可能导致晶闸管的损害,并提出了相应的建议...

| Abstract: | The non-periodic firing test is an important test of valve type tests for HVDC thyristor valve.For a complete valve,parallel capacitor method is normally adopted for testing.Some issues about recovery protection in the non-periodic firing tests have been discussed in this paper.Tests show that after the thyristor triggered,in recovery period,over high du/dt or re-triggered the thyristor,this may cause damage to thyristor.Base on this,the appropriate recommendations are proposed. |
