一、前言毛主席教导我们:“一个正确的认识,往往需要经过由物质到精神,由精神到物质,即由实践到认识,由认识到实践这亲多次的反复,才能够完成。”我们经过二年多的研究、试制,在兄弟单位的热情配合下,对真空接触器触头材料的性能和制造工艺进行了探讨,并取得了初步的认识。目前用我们提供的真空触头材料制作的高、低压真空接触器,已按照国际电工委员会提出的重任务接触器的试验标准,进行了多次试验,均
I. Foreword Chairman Mao taught us: “A correct understanding often needs to be accomplished through the repetition of materialism and spirit, spirituality and materialism, that is, from practice to understanding and from practice to realization.” We After more than two years of research, trial production, with the enthusiastic cooperation of the fraternal units, the contactors of vacuum contactor material properties and manufacturing processes were discussed, and achieved a preliminary understanding. Currently with the vacuum contact materials we provide the production of high and low voltage vacuum contactors, has been in accordance with the International Electrotechnical Commission proposed heavy duty contactors test standards, conducted a number of tests, both
