• 关键词: Abstract With the constant development of economy in China the scale of the coal mining is increasing rapidly. As main equipmentin the fully mechanized working face electric traction shearer has important influence on coal utilization efficiency and production so itoccupies an important position. At the same time due to the bad working environment in the working face of the shearer it requires higherreliability and working efficiency of the shearer. Frequency converter is the core control part of electric traction shearer so it is veryimportant to judge and remove its every possible fault which is essential for keeping the efficiency of the shearer and enhancing productionsafety.院采煤机 变频器 故障诊断 维修Key words coal mining machine frequency converter fault diagnosis maintenance中图分类号院TD421.6 文献标识码院A 文章编号院1006-4311（2014）15-0078-020
