Associated tightly with the stokes measured in small capacity current breaking and short - circuit breaking test duty t100a ( short arc , middle arc and long arc ) , the electric field distributions 3 ms after current zero have been calculated . the cold gas flow field corresponding with small capacity current breaking is calculated . based on the results derived from one - dimensioned gas flow field simulation , the two - dimensioned gas flow fields corresponding with short - circuit breaking test duty t100a ( short arc and middle arc ) are calculated as well 本文采用與試驗(yàn)緊密結(jié)合的方法,在給定機(jī)械行程曲線的基礎(chǔ)上對(duì)三峽工程中采用的550kvsf6斷路器在開斷小電容電流、短路開斷方式5短、中、長燃弧電流過零后3ms內(nèi)滅弧室二維靜電場(chǎng)分布進(jìn)行了分析計(jì)算;對(duì)該斷路器開斷小電容電流時(shí)近似的冷態(tài)場(chǎng)進(jìn)行了二維仿真分析計(jì)算;在對(duì)短路開斷方式5短、中、長燃弧一維氣流場(chǎng)進(jìn)行分析計(jì)算的基礎(chǔ)上進(jìn)一步采用一維氣流場(chǎng)和二維氣流場(chǎng)相結(jié)合的方法,對(duì)該斷路器開斷方式5短燃弧和中燃弧對(duì)應(yīng)的二維熱態(tài)場(chǎng)進(jìn)行了分析計(jì)算。
