DEVELOPMENT OF INTERRUPTING CHAMBER FOR ULTRA HIGH VOLTAGE SF 6 CIRCUIT BREAKER AND ITS NUMERICAL ANALYSES FOR WHOLE FIELD

A suggestion on the development of UHV SF 6 circuit breaker and three important new viewpoints about the design of interrupting chamber are put forward. A new two dimensional mathematical model of arc is presented and numerical analyses of 2 D electric field, 2 D flow field and dielectric recovery characteristics are introduced. All of them provide theoretical basis and computer simulation for increasing the interrupting ability of SF 6 circuit breaker and for the development of 550 kV one break circuit breaker.
