高压电机匝间试验设备的研制与应用

Development and Application of Turn-to-turn Test Instrument of High Tension Motor

矿井大型水泵、绞车、风泵等高压电机的检修,因工期太长影响生产。介绍一种在检修中采用电机定子绕组线圈单元件脉冲感应冲击法探测匝间的试验设备。该设备能够快速检测出电机线圈匝间故障,能准确完好地提高检修质量,降低检测时间,完善检修工艺,给电机的快速修理和稳定运行提供有利的保证。使用结果表明:该设备能够迅速检验出线圈匝间的故障,检测结果的精确度达到100%。

Examining and repairing high tension motors used in the water pump, wind pump and winch in mines always influence production. Introduces a test instrument which examines the winding of electromotor stator, impact of inductive pulse is the principle that the instrument adopts. It is able to quickly check the turn - to - turn faults of the circle, increase the repairing quality, reduce the measuring time, and improve the test craft. It also insure rapid repairing motor. Testing results showed that the testing instrument could quickly identify failure, the precision of result reached 100%.
