| 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 fixing, for which there are various requirements of electrical and mechanical properties. For example, under the prescribed operating voltage, lightning overvoltage and internal overvoltage, no breakdown or flashover along the surface occurs; under the prescribed long-term and short-term mechanical load, no damage or damage www.xiaoyuanshidiao.cnwww.handanbanjia.net.cn occurs; after long-term operation under the www.diandongmenn.cnwww.yanglaoyuann.com.cnprescribed mechanical, electrical load and various www.buxiugangfengtou.cnwww.zhidiaojia.net.cnenvironmental conditions, no obvious deterioration occurs; and insulator fittings do not appear obvious under the operating voltage. Corona discharge phenomenon, so as not to interfere with radio or television reception. Because insulators are widely used devices, they are also required to be interchangeable in connection with fittings. In addition, the technical standards of insulators also require various electrical, mechanical, physical and environmental tests to test the performance and quality of insulators according to different types and conditions of use. |
