云母-陶瓷复合绝缘子技术特性分析与应用

Investigation on the technical characteristics and application status of mica-ceramic composite insulator

轨道交通车辆牵引装备的电气设备接线用绝缘子既要具备足够的电气性能、力学性能、热性能和耐候性能,又要小型、轻量化,以满足特殊空间和使用环境条件下的应用需要。云母-陶瓷复合绝缘子兼具陶瓷绝缘子和合成绝缘子的综合优势,是一种理想的选择。文章研究分析了云母-陶瓷复合绝缘子的技术特性,介绍了其在机车电气设备上的应用情况。

To meet the application conditions of special space and operating environment,the insulator used on electric equipment of rail transportation traction vehicles should possess adequate electrical,mechanical,thermal and weathering properties,while remain small sized and light weighted.Mica-ceramic composite insulator can be an ideal choice as it possesses comprehensive advantages of mica insulator and composite insulator.This paper studies and analyzes the technical characteristics of the mica-ceramic composite insulator,and describes its application status on locomotive electric equipment.
