摘 要:為了解決接觸器動、靜鐵心出現(xiàn)的頻率振動問題,接觸器交流電磁系統(tǒng)通常是在鐵心上增加短路環(huán)。介紹了接觸器交流電磁系統(tǒng)鐵心短路環(huán)的作用及其工作原理,分析了短路環(huán)的結(jié)構(gòu)參數(shù)對鐵心最小吸力及平均吸力的影響。著重闡述了短路環(huán)內(nèi)、外磁通相位差對短路環(huán)性能的影響,給出了基于此磁通相位差來確定短路環(huán)綜合參數(shù)的方法,同時通過數(shù)值計(jì)算予以理論論證,并以實(shí)際接觸器研發(fā)應(yīng)用證明了此設(shè)計(jì)方法的有效性。
關(guān)鍵詞: 短路環(huán);噪音;最小吸力;磁通相位差;短路環(huán)綜合參數(shù);滯后疊加

Abstract: In order to solve the problem of frequency vibration in the dynamic and static iron core of the contactor, the contactor AC electromagnetic system usually adds a short circuit ring to the core. In this paper, the role and working principle of the core short-circuit ring of the contactor AC electromagnetic system are introduced, and the influence of the structural parameters of the short-circuit ring on the minimum and average suction of the core is analyzed. The influence of the phase difference between the internal and external magnetic flux of the short circuit ring on the performance of the short circuit ring is emphatically expounded, and the method of determining the comprehensive parameters of the short circuit ring based on the magnetic flux phase difference is given, and the theoretical demonstration is carried out through numerical calculation, and the effectiveness of the design method is proved by the actual development and application of contactor.
Key words: short circuit ring; noise; minimal suction; magnetic flux phase difference; short circuit ring comprehensive factor; lag superposition
