The development of 100 kV single-stage impulse voltage generator

The precondition to the study of breakdown property of nanocomposites is the impulse voltage testing system,of which the impulse voltage generator is the core device.Generally,the discharge voltage of multi-stage ultrahigh impulse voltage generator is higher than 1 000 kV,while that of small-scale pulse generator under local discharging is lower than 10 kV,and the impulse voltage of nanocomposites is around 100 kV.Therefore,to meet the requirements of high-voltage apparatus before operation,the 100 kV single-stage impulse voltage generator with low storage is developed.This paper introduces its working principle,and through simulation calculation fixes its element parameters of main circuit.The practical measurement proves that the generator meets the requirement of standard lightning wave.
