摘要
生产机械对电力拖动系统的控制线路要求,除动作在技术上应符合生产工艺、工作应可靠(不论在正常工作或不正常工作时均不会引起事故)外,还要求控制线路要简单,要经济.线路简单、经济与安全可靠措施有时是矛盾的,且常随着工作条件的变化而作不同的取舍.本文以现场常出现的一些具体问题加以讨论,并提出具体解决措施.
Abstract Control circuit in power driving system of production machinery is required to be of simple and economic , except its action should be tallied with technology and reliable on the operation never cause any accidents during both normal and ab - normal operation.Economic simplization circuit and reliable safty measure are sometime controdictory. And with changing of operation condition, there is a balance between them.some specific problems which are usually happened on site are discussed and certanin solution are provided in this article.
