Product Description
Mining Explosion proof Starter (QBZ-2× 120(80)/1140(660, 380)SF)
1. Function
This mine explosion-proof dual power vacuum electromagnetic starter is applicable in AC
50hz distribution system with voltage of 1140V, 660V, 380V in underground coal mines with
Explosive and dangerous gas(methane)and coal dust, it is used to offer automatic switching
To dual power supply dual fan and realize master-slave switching over operation mode of
Dual power supply and dual fan, ensuring uninterrupted ventilation in coal mine for long
Time, it is the most ideal control equipment dual fan in coal mines especially for mines with
Heavy gas.
