【摘要】 介绍了一种以乙烯基甲苯为活性稀释剂的聚酯亚胺无溶剂浸渍树脂。采用红外光谱及热失重对该聚酯亚胺浸渍树脂进行了表征,对其常规的绝缘性能进行了检测。采用模拟线棒试验对不同绝缘结构的介质损耗因素及击电压等性能进行了研究。结果表明,该浸渍树脂能够满足H级应用等级要求,可应用于不同结构电机的VPI绝缘处理。更多还原

【Abstract】 The characteristics,performance and application in the insulation structure of a polyester-imide solventless impregnating varnish are reported in this paper.The routine performances of the varnish had been studied by FT-IR,TGA etc.The simulating bars made from different mica tape and this impregnating resin were tested to examine the dielectric dissipation factor and breakdown voltage performance.The results showed that the varnish can be used as the vacuum pressure impregnating varnish of class H,and adapts to the vacuum pressure impregnating process of motors.更多还原
