摘要
研究了聚合物基正温度系数(PTC)材料的电性能测试方法,设计并组装了一套自恢复保险丝动作时间测试系统,使得动作时间的测量精度大大提高。并就散热环境对动作时间的影响进行了研究,探讨了PTC材料稳定性对所制备保险丝性能的影响。
The measuring method for electrical property of polymer PTC material was studied. Advice to test the response time of fuse was designed, then the test precision of the response time was greatly improved. The effect of heat dissipation on response time of fuse was also investigated. The dependence of property of fuse on the stability of PTC material was discussed.
