标准范围

IEC 60120:2020定义了一系列使用标准锁定装置的标准球窝联轴器的尺寸（参见IEC 60372），以便允许组装不同制造商提供的绝缘体或金属配件。本文件适用于帽、销和长杆类型的串绝缘子单元及其相关的金属配件。对于销球和承窝，尺寸适用于任何表面处理后的成品。销球在插座中的极端位置见附件。附录中给出了用于检查销球和插座尺寸的量规的典型示例。

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.
