ALFA UNION隔離開關(guān)STOL系列介紹
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 隔離開關(guān)是安裝在固定變電站中的設(shè)備。它們用于電路的空載切換。它們既可以手動(dòng)控制，也可以通過電磁鎖定終端位置，或者由帶有曲柄緊急控制的電機(jī)單元控制。 隔離開關(guān)狀態(tài)由輔助觸點(diǎn)發(fā)出信號(hào)。STOL隔離開關(guān)的模塊化設(shè)計(jì)支持各種版本。
