200A三相交流接触器的无火花控制

摘要

AC contactors are widely used in various industrial fields.However,any conventional applications show that their contacts need frequent maintenance as they are so often burnt,thus even causing peripheral equipment to be damaged,which would have serious effects on the normal operation of the industrial production.The sparkless AC contactors described in this paper can solve such a difficult problem successfully by using the by-pass techniqure of short-time current,so that they can keep operating with no need of maintenance.%交流接触器广泛用于各种工业领域。然而，传统用法中接触器的触点经常被烧损，需要频繁维护，使用寿命短，有时甚至造成周边设备损坏，严重影响工业生产的正常运作。本文中的无火花交流接触器应用短时间电流傍路技术成功地解决了这一难题，可做到免维护使用。
