标准范围

IEC 61466-1:20 16适用于交流用复合串绝缘子装置。标称电压大于1 000 V、频率不大于100 Hz的架空线路。它也适用于变电站或电力牵引线路中使用的类似设计的绝缘子。本标准适用于带球、承插、舌、U形夹、Y形U形夹或孔眼接头或其组合的复合型串绝缘子单元。本标准的目的是规定复合串绝缘子单元的机械特性的规定值，并定义复合串绝缘子单元上使用的联轴器的主要尺寸，以允许组装由不同制造商提供的绝缘子或配件，并允许在可行的情况下与现有装置互换。它还定义了复合串绝缘子单元的标准名称系统。与上一版相比，此版本包括以下重大技术变更:a)增加反映特高压实践的强度等级；b)纳入Y形配合孔尺寸的勘误表1:20 08。

IEC 61466-1:2016 is applicable to composite string insulator units for a.c. overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to insulators of similar design used in substations or on electric traction lines. This standard applies to string insulator units of composite type with ball, socket, tongue, clevis, Y-clevis or eye couplings, or a combination thereof. The object of this standard is to prescribe specified values for the mechanical characteristics of the composite string insulator units and define the main dimensions of the couplings to be used on the composite string insulator units in order to permit the assembly of insulators or fittings supplied by different manufacturers and to allow, whenever practical, interchangeability with existing installations. It also defines a standard designation system for composite string insulator units.This edition includes the following significant technical changes with respect to the previous edition:
a) Addition of strength classes reflecting UHV practice;
b) Inclusion of Corrigendum 1:2008 for Y fitting hole dimensions.
