三相异步电动机论文.doc

文档介绍：三相异步电动机论文 I 摘要随着电能应用的方便,电机设备已被广泛应用于工业生产的各个领域。电机在整个机械系统中起着举足轻重的作用,一旦电机发生故障就会影响整个系统的正常运行,甚至危及人身安全。所以对电机进行故障诊断非常重要。系统分析三相异步电动机的定。转子铁芯故障,转子轴承过热,损坏故障,电动机运行电压不正常,绕组接地,绕组短路,缺相,接地装置等故障的产生原因,并提出相应的具体解决办法。异步电动机的报复是个复杂的问题,在实际使用中,应按照电动机的容量、型式、控制方式和配电设备等不同来选择相适应的保护装置及启动设备,本文对于异步电动机保护盒故障诊断的方法的研究成果进行了归纳总结,分析说明,这些对异步电机的保护和诊断是有效的。关键词: 异步电机,故障诊断,电气故障,机械故障三相异步电动机论文 II Abstract The application of electricity and electrical equipment has been widely applied to industrial production in the fields. the motor mechanical system plays a prominent role as the stall will affect all the normal operation of systems and even threaten the security of person. to diagnose the motor for a very important. systems analysis with a three wire asynchronous the motor. the core set of iron; the rotor bearing overheated, the failure, the motor runs ina voltage not normal, winding grounding , Winding a short circuit grounding device, and wait for the failure of the cause and put forward some specific solution. the asynchronous motor revenge plex problem, in actual usage, in accordance with the capacity, type, control and distribution equipment different choice of protection device and the boot device and the protection of the asynchronous motor failure diagnosis of the method of research results in the analysis shows, summarizing , the motor for asynchronous protection and diagnosis is valid.
