摘　　要：通过晶闸管投切电容器组的电路模型,运用拉氏变换分析了无过渡过程投切电容器的两个必要条件,以及满足该条件的主电路的结构和触发时应解决的问题;详细分析了预充电无过渡过程TSC主电路的工作原理;针对现有的触发电路调试复杂、运行易受环境影响的特点,以其工作波形为基础,以星形连接的晶闸管投切电容器组为例,阐述了预充电动态无过渡过程TSC触发电路的设计应注意的事项、实现的途径及原理框图,该电路通过了实验室验证,文章在最后得出了合理的结论。To solve shutting flow-current and operating over-voltage why are aroused by switch on/off capacitor frequently in safety, running, and energy quality researching field of power system, It is necessary to analyse the circuit model of capacitor switch-on/off by thyristor. Two necessary conditions of non-transition process switch on/off capacitor are needed, and in order to meet with these conditions, some problems about the structure of the main circuit should be solved; Secondly, the work principle of the TSC main circuit of pre-charge non-transition process is introduced in detail. Based on the work waveform, some items pre-charge dynamic non-transition process block drawing and the way to realize the process are given. are expounded, which should be paid attention to when TSC trigger circuit is designed; Finally, the principle TSC trigger circuit of pre-charge dynamic non-transition
