| 绝缘子功能及要求 Function and requirement of insulators 绝缘子的主要功能是实现电气绝缘和机械固定，为此规定有各种电气和机械性能的要求。如在规定的运行电压、雷电过电压及内部过电压作用下，不发生击穿或沿表面闪络；在规定的长期和短时的机械负荷作用下，不产生破坏和损坏；在规定的机、电负荷和各种环境条件下长期运行以后， 不产生明显的劣化；绝缘子的金具，在运行电压下不产生明显的电晕放电现象，以免干扰无线电或电视的接收。因为绝缘子是大量使用的器件，对其连接金具还要求具有互换性。此外， 绝缘子的技术标准还根据型号和使用条件的不同，要求对绝缘子进行各种电气的、机械的、物理的以及环境条件变化的试验， 以检验其性能和质量。 The main function of insulators is to achieve electrical insulation and mechanical fixation. Therefore, various electrical and mechanical requirements are required. There is no breakdown or flashover on the surface under the prescribed operating voltage, lightning overvoltage and internal overvoltage; it does not produce damage and damage under the prescribed long-term and short-time mechanical load; no obvious deterioration is produced after long-term operation under the prescribed machine, electric load and various environmental conditions; insulation is not produced; The metal fittings under the operating voltage do not produce obvious corona discharge, so as not to disturb the reception of radio or television. Because insulators are widely used devices, their connection fittings also require interchangeability. In addition, the technical standard of insulators also requires a variety of electrical, mechanical, physical and environmental conditions to test the performance and quality of insulators according to the different types and conditions of use. |
