聚二苯醚坯布系用无碱玻璃布涂以聚二苯醚漆,經初烘而成。室温下是干态,不粘手。使用时加热熔固。耐热等级为H级以上。是上海绝缘材料厂的产品,其二苯醚漆系由苏州溶剂厂供应。我们试制的铁道干线用内燃机车同步牵引发电机和同步牵引电动机(后者也称为可控硅电机或无换器电机),其轉子均系凸极结构,綫圈为多匝銅排扁绕,H级绝缘。电机工作条件恶劣,在高速下、由于离心力的作用、銅排各匝间的錯动力很大、因而对轉子綫圈匝间绝缘的粘接力提出了严格的要求。
Polyene diphenyl ether fabric with non-alkali glass cloth coated with poly diphenyl ether paint, the initial baking. Room temperature is dry, not sticky hands. When used to heat the melt. Heat-resistant grade above H-level. It is a product of Shanghai Insulating Material Factory whose diphenyl ether paint supply is supplied by Suzhou Solvent Factory. Our trial production of railway mainline diesel locomotive synchronous traction generator and synchronous traction motor (the latter also known as SCR motor or no converter motor), the rotor is salient pole structure, the coil is a multi-turn copper flat winding, H-class insulation. Poor working conditions of the motor, at high speed, due to the role of centrifugal force, the copper bars between the turns of a large power offset, thus the inter-turn insulation of the rotor coil insulation put forward stringent requirements.
