IEC 60372-1984 “Locking devices for ball and socketcouplings of string insulator units:Dimensions and tests”标准维护的思考

Thoughts on Standard Maintenance of IEC 60372—1984 “Locking devices for ball and socket couplings of string insulator units:Dimensions and tests”

随着电力系统的发展,现行的IEC 60372"Locking devices for ball and socket couplings of string insulator units:Dimensions and tests"(Third edition)1984版已经无法涵盖和适应新的特高压大吨位绝缘子产品和技术的发展,包括对应于36和40两种新的联接标记的更高强度等级的绝缘子。笔者介绍了IEC TC36/MT21工作组维护IEC 60372标准的主要内容:包括结合国际工程实践经验,将已经被广泛应用的36、40两个联接标记加入到本标准中;研究是否增加锁紧销操作试验项目;研究并修改了原标准中L2和L5错误的问题;解决了28BW型锁紧销是否在本次修订中纳入标准的问题等。

With the development of power systems, the current IEC standard IEC 60372"Locking devices for ball and socket couplings of string insulator units: Dimensions and tests"(Third edition)1984 version has been unable to cover and adapt to the development of new UHV large insulator products and technologies, including the higher strength grade insulators corresponding to two new designated size of coupling 36 & 40. The main contents of the IEC TC36/MT21 working group for maintaining the IEC 60120 standard are introduced, including adding two designated size of coupling 36 and 40, which have been widely used to this standard in combination with international engineering practice;the problem of L2 and L5 errors in the original standard is researched and modified;solving the problem of whether the 28B W-chip is included in the standard in this revision, etc.
