我厂目前生产的 ZQ650-1电机是15年前设计的电机,由于当时绝缘材料品种的限制,因而在材料的选用上存在着困难,造成了ZQ650-1电机绝缘材料不配套,某些材料性能达不到要求等情况。如定子为H级绝缘,但主极匝间绝缘却采用E级的橡胶石棉纸,在长期高温运行条件下,势必造成石棉纸老化,补偿线圈采用无胶多层复合绝缘结构,整体性差,5151硅有机柔软云母板易吸潮,经常造成槽绝缘击穿等现象。
At present, the ZQ650-1 motor produced by our factory is a motor designed 15 years ago. Due to the limited variety of insulating materials at that time, there are difficulties in the selection of materials. As a result, the ZQ650-1 motor insulation materials are not compatible and some material properties Not meet the requirements and so on. If the stator is H-level insulation, but the main inter-turn insulation is E-grade rubber asbestos paper, under long-term high temperature operating conditions, will inevitably cause asbestos paper aging, compensation coil using glueless multi-layer composite insulation structure, the overall poor, 5151 Silicon organic soft mica board easy to absorb moisture, often resulting in slot insulation breakdown and so on.
