IEC 60700-1:20 15 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 IEC 60700-1:20 15适用于金属氧化物避雷器直接连接在阀端子之间的晶闸管阀，用于高压直流线路换向转换器。动力传输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。本标准规定的试验以空气绝缘阀为基础。对于其他类型的阀门，可以商定测试要求和验收标准。与上一版相比，该版本包括以下重大技术变化。 a)术语“冗余晶闸管电平”、“晶闸管电平”、“阀段”的定义已被更改以澄清。 b)在电介质直流测试要求中增加了注释。阀门支架、MVU、阀门的电压测试，规定在以相反极性重复测试之前，被测对象可能会短路接地数小时。在d.c.结束时可以遵循相同的程序。电压测试。 c)补充了型式试验期间允许的晶闸管电平故障表1。 d)增加了替代的MVU介电测试方法。 e)规定生产试验可包括常规试验和样品试验。 f)在定期点火和熄灭试验的试验要求中增加了一项规定，即在用阀门部分进行试验时，应应用试验的比例系数。

IEC 60700-1:2015 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.
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.
