摘要
农村水电站等工矿企业使用的交流接触器运行噪音大,电能损耗大。交流接触器采用交流启动、直流保持的运行方式,消噪节能效果明显。交流接触器无声节能控制对企业生产环境改善和企业节能促效益有着积极的现实意义。
The AC contactors used in rural hydropower stations and some other industrial and mining enterprises have too much noise and large power loss. when it runs by AC start and DC retention, it will contribute to noise-reducing and energy conservation. So the controling of AC contaetor＇s silent energy-conservation is with much positive and practical meaning for both improvement of enterprises＂ environment and its effectiveness increase by energy-saving.
