AIGCZN85M2-40.5型高壓真空斷路器是一種專為煉鋼爐等冶金行業(yè)設(shè)計(jì)的電力設(shè)備，其采用了先進(jìn)的長壽命永磁操動(dòng)機(jī)構(gòu)。這種永磁操動(dòng)機(jī)構(gòu)利用了高強(qiáng)度永磁材料產(chǎn)生持續(xù)且穩(wěn)定的磁場，替代傳統(tǒng)彈簧、液壓或電磁驅(qū)動(dòng)系統(tǒng)，從而減少了機(jī)械磨損和維護(hù)需求，顯著提高了斷路器的操作可靠性與使用壽命。
在40.5kV的工作電壓等級(jí)下，該斷路器具有快速分合閘能力，能夠在短時(shí)間內(nèi)切斷大電流，確保煉鋼生產(chǎn)過程中的電弧穩(wěn)定熄滅和電路安全切換，同時(shí)具備良好的耐高溫、抗腐蝕性能以及優(yōu)良的運(yùn)行穩(wěn)定性，滿足煉鋼爐及其他重載工業(yè)環(huán)境下的苛刻工作條件要求。
