摘 要：介绍了接触器的灭弧原理及方式，分析了交流接触器灭弧室结构及有效排气孔面积对电寿命的影响。以框架为150A接触器的灭弧室结构为例，对3个样机进行AC-4电寿命试验，试验结果表明对于同电流框架的接触器，其灭弧室结构对电寿命影响至关重要，且在满足电气间隙和爬电距离时，有效排气孔面积越大，电寿命次数越大。

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.
