2. Test configuration
As shown in Fig. 2, the test plat of current-zero characteristic in synthetic circuit is composed of the synthetic test circuit, measuring equipment, the test VCB and the high speed CMOS camera. The maximum capacity of the synthetic test circuit is 110kV/50 kA. The current source consists of Li and Ci while the voltage source is composed of Cv and Lv. The closing circuit breaker CB is used to introduce the main current while the triggered switch G is used to introduce the high TRV. The post-arc current measure equipment is composed of VI, Rsh, SG and CT1, which is designed and verified in our previous researches [14,15].Pt1, is used to measure the TRV while CT2 is Rogowski Coil which is used to measure the main current. The VCB is drove by the permanent magnet actuator(PMA) and the vacuum interrupter is transparent in order to observe the development of the vacuum arc by the high speed CMOS camera.
