标准摘要
[中文适用范围]： IEC 61466的本部分适用于标称电压大于1000 V、频率不大于100 Hz的交流架空线路复合串绝缘子单元。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。本标准适用于带有球@插座@舌形@U形夹@Y形U形夹或眼形联轴器@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，以便允许组装由不同供应商提供的绝缘子或配件。制造商，并在可行的情况下允许与现有装置互换。它还定义了复合串绝缘子单元的标准命名系统。注 1 IEC 61109 中给出了一般定义和测试方法。 注 2 本国际标准仅涉及联轴器组装所需的尺寸。未指定材料特性和工作负载。第 7 章规定了端部配件尺寸与强度等级的协调。 [外文原描述]： 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.
