Product Description
Mining Explosion proof Starter (QBZ-80+120)


1. Function


The flame-proof double power electric lockout vacuum electromagnetic starter for mining
Fan is made up of three back-to-bck starters for the main fan, back-up fan and drilling
Working area. The starter adopts double power (special power for the main and back-up fan)
So as to realize the change-over between the main and back-up fan power supply in the
Mine drilling tunnel. The back-up fan doesn't work when the main fan is working and the
Drilling proceeds as usual; When the main fan stops working, the back-up fan starts to work
So the drilling work remains normal. The starter is applicable in underground coal mines
With gas and coal dust.

2. Characteristics

2.1 With protective functions for short circuit, loss of phase, leakage lockout, over voltage,
Over current etc.
2.2 With lockout protective function for fan and power supply lockout
2.3 Two circuits automatic changeover
