Abstract：The compact impulse voltage generator is often used in the on-site impulse test of large-capacity electrical equipment due to its low inductance. In order to improve the synchronization performance of the device, it is necessary to set up multiple gas switches triggered by electrical pulse at the front stages. Due to the larger stray capacitance between the discharge stages, the triggering of multiple switches becomes more difficult. In 4.2MV impulse voltage generator, the external trigger system generates a hundred kilovolts nanoseconds pulse, which is applied to the trigger electrode of the first three-stage switch through isolation impedances. The isolation impedance should not only ensure that the nanosecond trigger pulse is effectively transmitted to the trigger electrode, but also isolate the overvoltage from main circuit discharge. The research results show that the resistance of kiloohms can effectively suppress the voltage coupled on the trigger system during synchronization, but reduce the amplitude of the trigger pulse seriously, and increase the wavefront time; the coupling inductance oscillates the pulse wavefront, and the inductance of microhenries cannot suppress the amplitude of the coupling voltage on the trigger system during synchronization; the capacitive coupled method can not only ensure the waveform quality of the trigger pulse, but also effectively reduce the synchronous coupling voltage on the trigger system.
