标准简介

适用范围：

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 C37.20.3… read more TM.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. read less
