标准范围

IEC 62501:2024适用于自换向换流阀，用于高压DC电力传输的三相桥式电压源换流器(VSC)或作为背靠背链路的一部分，以及动态制动阀。它仅限于电气类型和生产测试。本文件可用作储能系统（ESS）中使用的高压VSC阀的测试指南。本文件中规定的测试基于空气绝缘阀。试验要求和验收标准可用于指导规定其他类型阀门的电气型式和生产试验。与上一版相比，此版本包括以下重大技术变更:a)使用替代证据的条件作为新的表1插入；b）阀门支架直流电压试验的试验参数，7。3.2和MVU直流电压测试，8.4.1，更新；c)在9.4.2中对第9条阀端子之间的交流-直流电压试验进行了重组，并增加了单独交流和直流电压试验的替代试验；d)取消常规试验程序中的局部放电试验；e)增加了关于阀门部件容错的更多信息，附录B；f)增加阀门损失测定作为附录C。

IEC 62501:2024 applies to self-commutated converter valves, for use in a three-phase bridge voltage sourced converter (VSC) for high voltage DC power transmission or as part of a back-to-back link, and to dynamic braking valves. It is restricted to electrical type and production tests. This document can be used as a guide for testing of high-voltage VSC valves used in energy storage systems (ESS). The tests specified in this document are based on air insulated valves. The test requirements and acceptance criteria can be used for guidance to specify the electrical type and production tests of other types of valves. This edition includes the following significant technical changes with respect to the previous edition:
a) Conditions for use of evidence in lieu are inserted as a new Table 1;
b) Test parameters for valve support DC voltage test, 7.3.2, and MVU DC voltage test, 8.4.1, updated;
c) AC-DC voltage test between valve terminals, Clause 9, is restructured and alternative tests, by individual AC and DC voltage tests, added in 9.4.2;
d) Partial discharge test in routine test program is removed;
e) More information on valve component fault tolerance, Annex B, is added;
f) Valve losses determination is added as Annex C.
