电源相序对三相晶闸管移相控制器工作状态的影响

Influence of Supply Phase Sequence on the Operation of 3--Phase Thyristor Phase--shifting Controller

分析了采用双窄脉冲触发时,电源相序对三相晶闸管移相控制器工作状态影响的机理,揭示了这种影响与主变压器和同步变压器接法的关系。此外还介绍了一种能完全排除这种影响的新型触发电路—双内补脉冲触发电路。所得结论已被实验证实。

The influence of the phase sequence on the operation of a 3-phase thyristor phaser- shifting controller using double pulse firing is analysed in this paper. The relations between this influnce and wiring of main transformers and synchronous transformers are revealed. To eliminate the influance completely a novel firing—double internally complementary pulse firing circuit is introduced. And all conclutions have been confirmed through experiments.
