目前,称套配电装置又叫成套配电柜,也是以开关为主的成套电器,故也俗称开关柜。它用于配电系统,作为接受与分配电能之用。据电压高低,它可分为高压开关柜和低压开关柜两大类:按装置地点的不同,又分户外式与户内式(10kv及以下的多采用户内式);按开关电器是否可以移动,又可分为固定式和手车式。可见,高压开关柜是成套配电设备的一种,是有由制造厂成套供应的高压配电装置。在这种封闭或半封闭的柜中可装设各种高压电器、测量仪表、保护电器和控制开关等等。通常一个柜就构成一个单元回路(必要时也可用两个柜),所以一个柜也就成为一个间隔。使用时可按设计的主回路方案,选用适合各种电路间隔的开关柜,然后使可组成整个高压配电装置。也具有占地少、安装使用及维护检修方便,适于大量生产等特点,故应用很广泛。
然而,现有的配电系统的功能单一。当配电电压正常时,现有的配电系统用于向用户端的负载进行供电;当配电电压不正常时,配电系统停止向用户端的负载进行供电,无法持续地给负载供电。
