摘要
依照TSC投切机理,开发了两种工作可靠、使用元件少、成本低的TSC投切开关的新型主回路结构,简称为“2+1”电路和“2+2”电路。满足了TSC投切机理,投入瞬时,电流无冲击,平稳过渡。不仅介绍了“2+1”电路和“2+2”电路工作机理,晶闸管触发原理,投切过渡过程电流、电压情况等,还简单介绍针对上述两种主电路所开发的触发控制电路。
Based on the principle of TSC, two novel designs for the main circuits and their triggering modules of TSC, which could work reliable with fewer electronic components and cost less, are discussed in the paper. Called “2+1”circuit and “2+2”circuit. When the switch is on, no impact current is resulted and smooth transition is achieved. The paper also introduces the mechanism of “2+1”and “2+2”circuits, including the thyristors triggering time, the transient capacitor voltage and current during the switch transition. In the end, simple triggering modules are developed for the above two circuits, and their triggering mechanisms are also addressed respectively.
