| 用途 Application |
Ⅱ QBZ系列矿用隔爆型真空电磁起动器适用于具有爆炸性危险和煤尘的煤矿井下，在交流50Hz，电压至660V 或1140V的电力系统中，作为就地或远距离控制额定电流分别至80A、120A、200A的矿用隔爆型三相鼠笼式异步电动机的起动或停止之用。并可在被控制电动机停止时进行换向，同时对电动机及有关电路进行过载、短路、断相、主电路漏电闭锁和失压保护。起动器特别适用于频繁操作、重负荷的煤矿机械设备控制
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. |
