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 are expounded

which should be paid attention to when pre-charge dynamic non-transition process TSC trigger circuit is designed;Finally

the principle block drawing and the way to realize the TSC trigger circuit of pre-charge dynamic non-transition process are given.
