| 绝缘子 Insulator 安装在不同电位的导体或导体与接地构件之间的能够耐受电压和机械应力作用的器件。绝缘子种类繁多，形状各异。不同类型绝缘子的结构和外形虽有较大差别，但都是由绝缘件和连接金具两大部分组成的。 Devices that are capable of withstanding voltage and mechanical stress between conductors or conductors with different potentials. There are various types of insulators and different shapes. Although the structures and shapes of different types of insulators are quite different, they are made up of two parts: insulation parts and connecting fittings. 绝缘子是一种特殊的绝缘控件， 能够在架空输电线路中起到重要作用。早年间绝缘子多用于电线杆，慢慢发展于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，就叫绝缘子。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。 Insulator is a special insulation control, which can play an important role in overhead transmission lines. In the early years, insulators were used in electric poles, slowly developed at the end of the high voltage wire connection tower with a lot of disc insulators, which were designed to increase the distance of creeping, usually made of glass or ceramics, and called insulators. Insulators should not fail due to various mechanical and electrical stresses caused by changes in the environment and electrical load conditions, otherwise the insulators will not have a significant effect and will damage the use and operation life of the whole line. |
