This paper discusses the operation case of the high voltage big capacity pulse capacitor used in high voltage circuit breaker test loop

introduces the pulse capacitor parameter design and the research of durability test. Due to the use condition of oscillatory discharge conditions is severe

and dielectric with-stand test voltage is up to the 1.3 UN

so the design and manufacture is difficult. Through the durability test on model capacitor

finally determines the field intensity and the main technical parameters

such as core structure. This paper describes the influence of the inherent inductance capacitor on its performance

analyzes the causes of inductance produced by capacitors

and introduces some measures to reduce the capacitor inductor. Using the Ansys simulation software to pulse capacitor tank under fault condition

the more physical field of the blast resistance coupling simulation

analyzes the weak spot in the tank.
