IEC 60214-1:20 14适用于电阻器和电抗器类型的有载分接开关、断电分接开关及其电机驱动机构。它主要适用于根据IEC 60296浸入矿物绝缘油中的分接开关，但也可用于具有空气或气体绝缘或浸入其他绝缘液体中的分接开关，只要条件适用。它主要适用于具有电弧触点的分接开关，但在条件适用的情况下，也可用于无电弧有载分接开关（如电子开关）。IEC 60214的这一部分适用于所有类型的电力和配电变压器以及电抗器。它不适用于安装在铁路机车车辆上的变压器和电抗器。这第二版取消并取代了2003年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: a)纳入对真空型有载分接开关的要求， b)纳入对气体绝缘分接开关的要求， c)改变型式试验以适应服役条件， d)参考最新版IEC 60076-3:20 13。

IEC 60214-1:2014 applies to on-load tap-changers of both resistor and reactor types, de-energized tap-changers, and their motor-drive mechanisms. It applies mainly to tap-changers immersed in mineral insulating oil according to IEC 60296 but may also be used for tap-changers with air or gas insulation or immersed in other insulating liquids insofar as conditions are applicable. It applies mainly to tap-changers with arcing contacts but may also be used for arcing-free on-load tap-changers (such as electronic switching) insofar as conditions are applicable. This part of IEC 60214 applies to power and distribution transformers of all types and also to reactors. It does not apply to transformers and reactors mounted on railway rolling stock. This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) incorporation of requirements on vacuum type on-load tap-changers,
b) incorporation of requirements on gas insulated tap-changers,
c) changes in the type tests to fit with the service conditions,
d) reference to the newest edition of IEC 60076-3:2013.
