Abstract : owing to the defects in high cost and short life of the copper contact shoes on electric arc furnace, it was redesigned and replaced with graphite contact shoes. by using it to a 6. 3mva electric arc furnace, result shows that the operating life is longer and the furnace hot ? down time is decreased obviously. operating cost reduced greately
文摘:針對電爐銅頭電瓦成本高、壽命短的缺陷，對其重新設計改造，以石墨導電瓦代替銅頭導電瓦，並應用在6 . 3mva電爐上，結果其使用壽命長，爐子熱停次數顯著減少，生產成本大幅度降低。 -

In this paper, associated with the key problem of 550kv sf6 high voltage circuit breaker which is used in gis of three gorges project, the mathematical models of static electrical field and one - dimensioned and two - dimensioned gas flow field during the overall breaking process in arc chamber of circuit breaker are developed. on the basis of gas discharge theory, the criteria to judge the interruption success is determined. through the combination of one - dimensioned and two - dimensioned gas flow field software, the problem that the primary two - dimensioned gas flow field software ca n ' t calculate the hot gas flow field has been effectively solved
本文結合長江三峽550kvgis中sf6斷路器的科技攻關項目，建立了斷路器開斷過程中滅弧室內靜電場、一維氣流場、二維氣流場的數學模型；根據氣體放電的基礎理論選定了衡量斷路器能否成功開斷的標準，並通過一維和二維氣流場的有機結合，有效地解決了原二維氣流場計算軟體無法計算有載開斷的難題，具有較強的工程實用性。
