| 用途 Application |
Ⅱ QBZ系列礦用隔爆型真空電磁起動器適用于具有爆炸性危險和煤塵的煤礦井下，在交流50Hz，電壓至660V 或1140V的電力系統(tǒng)中，作為就地或遠距離控制額定電流分別至80A、120A、200A的礦用隔爆型三相鼠籠式異步電動機的起動或停止之用。并可在被控制電動機停止時進行換向，同時對電動機及有關(guān)電路進行過載、短路、斷相、主電路漏電閉鎖和失壓保護。起動器特別適用于頻繁操作、重負荷的煤礦機械設(shè)備控制
Ⅱ series exploding isolation type vacuum electromagnetic starter used for mining applicable to coal mine where has explosible dangerous gas and coal dust.In the electric systrm with AC50Hz voltage up to 660V or 1140V,used for local and remote control starting and stop when the controlled electromotor stop,mhile,it has protection functions such as over load,short circuit,loss of phase main circuit electrical leakage locking and voltage loss for electromotor and relative circuit.The starter is especially applicable for coal mine machniery equipment with frequent operation and heavy load coal mine machinery. |
