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
本文採用與試驗緊密結合的方法,在給定機械行程曲線的基礎上對三峽工程中採用的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內滅弧室二維靜電場分佈進行了分析計算;對該斷路器開斷小電容電流時近似的冷態場進行了二維模擬分析計算;在對短路開斷方式5短、中、長燃弧一維氣流場進行分析計算的基礎上進一步採用一維氣流場和二維氣流場相結合的方法,對該斷路器開斷方式5短燃弧和中燃弧對應的二維熱態場進行了分析計算。
