标准范围

IEC 60372:2020适用于与串绝缘子单元的球窝联轴器一起使用的锁定装置，以及与IEC 60120中标准化的相应金属配件一起使用的锁定装置，当它们单独提供时。本文件的目的是-定义锁定装置的形状和一些标准尺寸，-定义锁定装置的测试方法，-说明供货的验收条件，-给出其他尺寸仅用于指导制造。第四版取消并取代了1984年出版的第三版。与上一版相比，此版本包括以下重大技术变更:a.推出了两种新的指定尺寸的联轴器，36和40；b.删除了28B W-clip的相关内容；c.附件A是信息性的，附件B是规范性的，附件C是信息性的。

IEC 60372:2020 is applicable to locking devices used with ball and socket couplings of string insulator units and used with the corresponding metal fittings standardized in IEC 60120, when they are supplied separately.The object of this document is
- to define the shapes and some standard dimensions for locking devices,
- to define the test methods for locking devices,
- to state the acceptance conditions for supply,
- to give other dimensions for guidance of manufacturing only.
This fourth edition cancels and replaces the third edition published in 1984. This edition includes the following significant technical changes with respect to the previous edition:
a. Two new designated size of couplings, 36 and 40, were introduced;
b. the relevant content of the 28B W-clip was deleted;
c. Annex A is informative, Annex B is normative, Annex C is informative.
