IEC？62271-102:2018适用于交流隔离开关和接地开关，设计用于室内和室外安装，标称电压高于1？000？V对于服务频率不超过60？赫兹。这第二版取消并取代了2001年出版的第一版，修正案？1:20 11和修正案2:20 13。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:根据IEC 17/1025/RQ的新编号，以与ISO/IEC指令保持一致，第？2和IEEE Std.C 37.100.1；条款编号已与IEC保持一致？62271-1:2017;范围已扩展到涵盖所有室内和室外安装。除了其它功能之外，还包括对具有断开和/或接地开关功能的开关设备的考虑；评级已从附件B、C和E移至第5条；子条款的顺序现在对应于第7条中子条款的顺序；为母线转移电流和母线转移电压分配了新的额定值；增加了接地开关机械耐久性的新等级（M1）；子条款“接地开关的电气耐久性额定值”现在称为“接地开关短路能力的分类”；增加了结冰评级的新子条款；增加了对总线充电交换能力进行分类的新子条款；新增了联锁装置的耐受性要求；修改了符合隔离开关隔离距离要求的方式；位置的设计和施工要求-指示设备已被修改，符合位置指示和信号的要求；操作力的值已经改变；如有必要，已对测试程序和验证标准进行了修订和修改；改变了非同时闭合接地开关单相试验期间施加电压的要求；删除了不可验证的需求；增加了一个新的子条款，用于测试机械联锁装置；如果仪器使用条件的温度限值（由制造商定义）高于+40？°C或以下？5？℃，并给出了更详细的测试程序；验证位置指示装置正常运行的测试程序允许对所使用的每种技术进行更实际的测试；增加了新的附件B，标题为:“隔离开关和接地开关所需的电流切换能力”；增加了新的附件C，标题为:“型式试验的试验数量公差”；增加了新的附件E，标题为:“型式试验有效性的扩展”。

IEC？62271-102:2018 applies to alternating current disconnectors and earthing switches, designed for indoor and outdoor installations for nominal voltages above 1？000？V and for service frequencies up to and including 60？Hz.
This second edition cancels and replaces the first edition published in 2001, Amendment？1:2011 and Amendment 2:2013. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:

1. new numbering according to IEC 17/1025/RQ to harmonize with ISO/IEC Directives, Part？2, and IEEE Std. C37.100.1;
2. clause numbering has been aligned with IEC？62271-1:2017;
3. the Scope has been extended to cover all indoor and outdoor installations. Consideration of switching devices having disconnecting and/or earthing switch functionalities, apart from other functions, are also covered by this document;
4. ratings have been moved from Annexes B, C and E to Clause 5; the order of the subclauses now corresponds to the order of subclauses in Clause 7;
5. new rating values for bus-transfer current and bus-transfer voltage have been assigned;
6. new class of mechanical endurance for earthing switches has been added (M1);
7. subclause "Rated values of electrical endurance for earthing switches" is now called "Classification of earthing switches for short-circuit making capability";
8. new subclause with ratings for ice-coating has been added;
9. new subclause with classification of bus-charging switching capability has been added;
10. new withstand requirements for interlocking devices have been added;
11. the way to comply with the requirements of the isolating distance of disconnectors has been modified;
12. design and construction requirements for position-indicating devices have been modified, aligning the requirements for position indication and signalling;
13. the value of the operating force has been changed;
14. the test procedures and validation criteria have been revised and modified where necessary;
15. requirements for applied voltage during single-phase test on non-simultaneous closing earthing switches have been changed;
16. non-verifiable requirements have been deleted;
17. a new subclause has been added for testing mechanical interlocking devices;
18. the high- and low-temperature test is mandatory if the temperature limits for the service conditions of the apparatus (defined by the manufacturer) are above +40？°C or below？5？°C, and a more detailed testing procedure is given;
19. the testing procedure to verify the proper functioning of the position-indicating device allows a more practicable testing for every technology used;
20. a new Annex B has been added with title: "Current-switching capability required of disconnectors and earthing switches";
21. a new Annex C has been added with title: "Tolerances on test quantities for type tests";
22. a new Annex E has been added with title: "Extension of validity of type tests".
