252kV自能式SF_6断路器灭弧室电场计算

Calculation of electric field and insulation analysis of 252?kV self-extinguish SF_6 circuit breaker chamber

以126kV自能式SF6断路器的灭弧室结构为依据,给出了126kV和252kV自能式SF6断路器的灭弧室电场计算结果,计算结果表明,252kV自能式SF6断路器灭弧室结构满足绝缘要求,为252kV自能式SF6断路器的整体设计提供了理论依据.

Based on the chamber structure of 126?kV selfenergy SF\-6 circuit breaker, the chamber electric field of 126?kV and 252?kV selfenergy SF\-6 circuit breaker is computed.By the analysis of the calculation results,the insulation structure and size of 252?kV selfenergy SF\-6 circuit breaker is confirmed. Theory basis of integer design of 252?kV selfenergy SF\-6 cirucit breaker.
