对T1168H环保型耐高温浸渍树脂的耐热性能、环保性能、储存稳定性等进行了研究,并制作模拟线圈,对其在牵引电机上的应用性能进行测试。研究结果表明:T1168H树脂综合性能较优,温度指数达到222 ℃,挥发份低且无毒环保,树脂贮存性能稳定；浸渍T1168H树脂的线圈绝缘在击穿电压、绝缘电阻(浸水前后)以及介质损耗因数等方面性能优异,能够满足牵引电机对绝缘浸渍树脂的要求。

The heat resistance, environmental protection performance and storage stability of T1168H environmentfriendly high temperature impregnating resin were studied. The application performance of T1168H in traction motor was tested on a sample coil. The results showed that the temperature index of T1168H resin reached 222 ℃. Besides, T1168H resin had the advantages of low volatile content, no toxicity and environmental protection, and storage stability. The coil impregnated with T1168H resin exhibited excellent insulation performances in breakdown voltage, insulation resistance and dielectric loss factor. This material could meet the traction motor insulation requirements.
