标准摘要
[中文适用范围]： 本标准旨在定义一系列标准球窝耦合的尺寸，使用标准锁紧装置（见IEC 60372），以便组装由不同制造商提供的绝缘子或金属配件。本文件适用于帽钉型和长棒型的悬式绝缘子单元及其相关的金属配件。对于销球和套筒，尺寸适用于经过任何表面处理后的成品。销球在套筒内的极限位置见附录A。检查销球和套筒尺寸的典型量规示例见附录B。注：本标准仅处理组装所需的尺寸。材料属性和工作载荷未作规定。尺寸与强度等级的协调在IEC 60305和IEC 60433中规定。 [外文原描述]： IEC 60120:2020 define the dimensions of a series of standard ball and socket couplings using the standard locking devices (see IEC 60372) in order to permit the assembly of insulators or metal fittings supplied by different manufacturers. This document applies to string insulator units of the cap and pin and long rod types and their associated metal fittings. For the pin ball and the socket, dimensions apply to the finished product after any surface treatment. Extreme positions of the pin ball in the socket are given in annex. Typical examples of gauges for checking the dimensions of pin balls and sockets are given in annex.
