大型电机VPI绝缘体系的关键技术研究
Research on Essential Technology of Large Generator VPI Insulating System
【摘要】 本文介绍了哈电(哈尔滨电机厂有限责任公司)在大型电机定子线棒真空压力浸渍(Vacuum Pressure Impregnation,VPI)绝缘体系的关键技术方面的研究成果。首先,介绍了优选的VPI绝缘体系原材料(浸渍漆、少胶云母带及防晕材料)的性能;其次,介绍了VPI绝缘体系应用的国产化关键设备(包括储存漆、输回漆系统、浸渍漆系统)性能;最后,通过利用水电真机定子线棒进行大量工艺试验,确定了VPI定子线棒绝缘包扎工艺、浸渍工艺、一次成型防晕处理工艺及热压工艺,线棒的各项性能指标均达到标准优等品要求,目前哈电的VPI绝缘技术已达到国际先进水平。
【Abstract】 The paper introduces research results of key technologies of VPI(Vacuum Pressure Impregnation) insulation system for large generator stator coils in HEC(Harbin Electric Machinery Company Limited). Firstly, raw material properties of VPI insulation system(such as impregnation lacquer, less-resin mica tape and anti-corona material) optimized selected are introduced. Secondly, key equipments properties of VPI insulation system(such as storge lacquer system, transport and return lacquer system and impregnating system) manufactured by domestic corporations are introduced. At lastly, plenty of tests of hydrogenerator stator coils had been carried out, and the test results ascertained some technologies which were about VPI stator coil insulation wrapping quelity, impregnate technology, onetime-molding-anticorona technology and hot-press technology. The stator coils properties can up to scratch of excellent product. Nowadays VPI insulation technology in HEC had rearch advanced international standards.
