正弦波同步触发电路及其晶闸管充电装置中的应用

Synchronous Trigger Circuit of Sine Wave and its Application to the Replenish Electricity

正弦波同步触发电路是为晶闸管提供触发脉冲。阐述了正弦波同步触发电路的组成及各部分的作用,具体分析了一些出现故障的原因,并在十几年运行的经验基础上,提出了一些解决实际问题的方法。

The synchronous trigger circuit of sine wave provides the trigger fluctuation for triggering thyristor. In this paper the composition and the function of all parts of the synchronous trigger circuit of sine wave is elaborated .Based on the depiction the trigging course of the trigger circuit, the rea- son of some malfunctions is analyzed. In terms of operational experiences in the past ten years, some methods about resolving some problems in application is put forwarded.
