特大型提升机同步电机转子故障研究分析

Oversize hoist synchronous motor rotor fault analysis

本文对麻家梁矿主井7000kW同步电机转子线包脱落,转子线包匝间短路、阻尼铜条松动、发出异响,最终致使铁芯边缘处放电灼伤铁芯槽故障现象做出细致观察,并对故障原因进行研究分析,对保证主井提升机电机的正常运转和维护有重要意义。

Beam in this paper, Majialiang coal Main shaft 7000 kw synchronous motor rotor line package loss, rotor line package turn-to-turn short circuit, loose damping copper bar, a sound, leading to burn core core edge discharge groove fault phenomenon make meticulous observation, and to research and analysis of the cause of the problem, to ensure that the main well promote the normal operation and maintenance of mechanical and electrical machine has important significance.
