背景技术Background technique
在高型高压电线连接塔的一端挂了很多盘状的绝缘体，它是为了增加爬电距离的，通常由玻璃或陶瓷制成，叫做绝缘子。绝缘子在架空输电线路中起着两个基本作用，即支撑导线和防止电流回地，这两个作用必须得到保证，绝缘子不应该由于环境和电负荷条件发生变化导致的各种机电应力而失效，否则绝缘子就不会产生重大的作用，就会损害整条线路的使用和运行寿命。A lot of disc-shaped insulators are hung at one end of the high-voltage wire connection tower to increase the creepage distance, usually made of glass or ceramics, called insulators. Insulators play two basic roles in overhead transmission lines, namely supporting conductors and preventing current from returning to the ground. These two roles must be guaranteed. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulator will not play a significant role, and it will damage the service and operating life of the entire line.
现有复合绝缘子伞套材料为硅橡胶材料，机械性能有待于提高，由于鸟类喜欢啄吃复合绝缘子伞裙或护套，从而暴露芯棒，影响复合绝缘子的绝缘性能，在带电运行中存在一定的安全隐患，会给国家造成重大经济安全损失。The existing composite insulator umbrella cover material is silicone rubber material, and the mechanical properties need to be improved. Because birds like to peck at the composite insulator umbrella skirt or sheath, the mandrel is exposed and the insulation performance of the composite insulator is affected. It will cause major economic security losses to the country.
