摘要
煤矿负荷大多是感应式电动机,属感性负荷,功率因数低。同步电动机可以在超前的功率因数下工作,但必须正确地调节电动机的励磁电流才能充分发挥其补偿能力,该文笔者根据理论和实践经验,介绍了正确的调节方法,具有一定借鉴意义。
Most of the coal load induction motor, an emotional load, low power factor. In synchronous motor power factor ahead of the work, it must be properly regulated motor excitation current compensation can give full play to their ability, according to the author of the text of the theory and practical experience on the right conditioning methods, which have a certain learn.
