ALFA UNION隔离开关STOL系列介绍
STOL disconnectors are devices which are installed in stationary substations. They are used for no-load switching of electrical circuits. They are controlled either manually, with possibility of electromagnetic blocking of end positions, or by a motor unit with emergency control by a crank handle. The disconnector status is signalled by auxiliary contacts. Modular design of the STOL disconnector enables various versions.
STOL 隔离开关是安装在固定变电站中的设备。它们用于电路的空载切换。它们既可以手动控制,也可以通过电磁锁定终端位置,或者由带有曲柄紧急控制的电机单元控制。 隔离开关状态由辅助触点发出信号。STOL隔离开关的模块化设计支持各种版本。
