1.1范围 本标准涵盖额定值在1 kV至38 kV之间的室内交流开关，用于金属封闭开关设备，如下所示: a） 静止或抽出 b） 手动或电动操作 c） 熔化的还是未熔化的 a这个词？A.印多拉？A.旨在表明外壳为开关提供一定程度的保护，外壳可能适用于室内、室外或其他工作条件，并符合IEEE Std C37规定的开关设备组件的要求。20.2TM或IEEE标准C37。20.3米。1. 本标准不适用于IEEE Std C37中用于地下或垫装开关设备的开关。 74TM或IEEE Std C37中的高压空气开关。30TM。 在这个标准中，a？开关a？应视为本范围定义的金属封闭、室内、三相交流中压开关。 有一些开关设计具有短路电流中断能力，这些设备 本标准仅在满足所列测试要求的范围内涵盖。然而，由于额外的能力，需要进行额外的测试，并应咨询制造商。

This standard covers indoor ac switches rated above 1 kV through 38 kV for use in metal-enclosed switchgear as follows: a) Stationary or drawout b) Manual or power operation c) Fused or unfused The term ''indoor'' is intended to indicate that the enclosure provides a degree of protection to the switch and the enclosure may be suitable for indoor, outdoor, or other service conditions and complies with the requirements of switchgear assemblies as defined by IEEE Std C37.20.2TM or IEEE Std C37.20.3TM.1 This standard does not apply to switches for use in subsurface or pad-mounted switchgear in IEEE Std C37.74TM or to high-voltage air switches in IEEE Std C37.30TM. Within this standard, the words "switch(es)" shall be considered to mean metal-enclosed, indoor, three-phase, ac medium-voltage switch(es) as defined by this scope. There are switch designs that have short-circuit current interrupting capability, and these devices are covered by this standard only to the extent of meeting the listed testing requirements. However, due to the additional capability, additional testing is required and the manufacturers should be consulted.
