Abstract

Abstract

The breakdown test apparatus with the measurement system of voltage and current signals in liquid dielectrics is designed; The relations of repetitive frequency, electrode shape and gap to some breakdown characteristics of liquid dielectrics such as breakdown field, breakdown voltage, breakdown time, and so on, are theoretically analyzed. And the insulating capabilities of three typical liquid dielectrics (transformer oil, dodecylbenzene, and castor oil) are compared, which indicates that a ranking of the withstand voltage rate for three materials , from smallest to largest, is dodecylbenzene, transformer oil and castor oil.
- short-pulsed,
- liquid dielectrics,
- breakdown characteristic,
- pulse power technology
