摘 要：介紹了接觸器的滅弧原理及方式，分析了交流接觸器滅弧室結(jié)構(gòu)及有效排氣孔面積對電壽命的影響。以框架為150A接觸器的滅弧室結(jié)構(gòu)為例，對3個樣機(jī)進(jìn)行AC-4電壽命試驗，試驗結(jié)果表明對于同電流框架的接觸器，其滅弧室結(jié)構(gòu)對電壽命影響至關(guān)重要，且在滿足電氣間隙和爬電距離時，有效排氣孔面積越大，電壽命次數(shù)越大。

Abstract: Introduction was made to the principle and method of arc extinction of contactor and analysis was made to the arc extinguish chamber structure of AC contactor and the impacts of effective gas escape area on electrical life. Taking the arc extinguish chamber structure of frame 150 A contactor as an example, AC-4 electrical life test was carried out for 3 sample machines. The test result shows that for same current frame contactors, its arc extinguish chamber structure has vitally important impact on electrical life, and providing the requirement of electric gap and distance is met, the bigger the effective gas escape area is, the larger the number of electrical life times is.
        Key words: AC contactor; arc extinguish chamber; electrical life; arc chute
