概述/Specification

VS1-12型侧装式真空断路器系户内高压开关设备，适用于额定电压12千伏、频率50Hz的三相电力系统中，作为保护和控制电器使用，由于真空断路器的特殊优越性，尤其适用于需要额定电流下的频繁操作，或多次开断短路电流的场所。

VS1-12型侧装式真空断路器采用固定式安装，主要用于固定式开关柜，该断中器既可单独使用，又可用于环网供电、箱式变或各种非标供电系统。

VS1-12 side-mounted type vacuum circuit breaker is a kind of indoor high voltage switch device which is used in the AC three-phase power system offrequency 50HZ,rated voltage 12KV to be the protection and control unit.Because of the special superiority of vacuum circuit breaker,especially suitable forapplications that require frequent operation at rated operating current or mutiple open short-circuit breaking current location.It is especially suitable to theplace requiring frequent operations.

VS1-12 side-mounted type vacuum circuit breaker adopts fixed installation,which is mainly used in the fixed switchgear.It can be used alone or used in ring

network power supply system,box-type variable systerm and non-standard power supply system to protect and control the Transmission and distribution line.
