高压直流 (HVDC) 输电用晶闸管阀 第 1 部分：电气测试

[中文适用范围]： IEC 60700-1:2015 RLV 包含官方 IEC 国际标准及其红线版本。 Redline 版本仅提供英文版本，为您提供了一种快速、简单的方法来比较官方 IEC 标准与其先前版本之间的所有更改。 IEC 60700-1:2015 适用于在阀岛之间直接连接金属氧化物避雷器的晶闸管阀，用于高压直流输电的线路换向转换器或作为背靠背链路的一部分。它仅限于电气类型和生产测试。本标准规定的试验基于空气绝缘阀门。对于其他类型的阀门，可以商定测试要求和验收标准。相对于先前版本，此版本包括以下重大技术更改。 a) 为澄清起见，更改了术语“冗余晶闸管电平”、“晶闸管电平”、“阀部分”的定义。 b) 阀门支架、MVU、阀门的介电直流电压试验的试验要求增加了注释，规定在以相反极性重复试验之前，可将被试物短路接地数小时。直流电压测试结束时可以遵循相同的程序。 c) 补充了表1型式试验中允许的晶闸管电平故障。 d) 添加了替代的 MVU 介电测试方法。 e) 规定生产试验可包括例行试验和样品试验。 f) 在定期点火和熄灭试验的试验要求中增加了当用阀部分进行试验时应应用试验比例因子。 2017年1月勘误的内容已包含在本副本中。 [外文原描述]： IEC 60700-1:2015 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60700-1:2015 applies to thyristor valves with metal oxide surge arresters directly connected between the valve terminals, for use in a line commutated converter for high voltage d.c. power transmission or as part of a back-to-back link. It is restricted to electrical type and production tests. The tests specified in this standard are based on air insulated valves. For other types of valves, the test requirements and acceptance criteria can be agreed. This edition includes the following significant technical changes with respect to the previous edition. a) Definitions of terms "redundant thyristor levels", "thyristor level", "valve section" have been changed for clarification. b) The notes were added to test requirements of dielectric d.c. voltage tests for valve support, MVU, valve, specifying that before repeating the test with opposite polarity, the tested object may be short-circuited and earthed for several hours. The same procedure may be followed at the end of the d.c. voltage test. c) Table 1 on thyristor level faults permitted during type tests was supplemented. d) The alternative MVU dielectric test method was added. e) It was specified that production tests may include routine tests as well as sample tests. f) It was added into test requirements for periodic firing and extinction tests that a scaling factor for tests shall be applied when testing with valve sections.
