1140V&sol660V Mining Flameproof and Intrinsic Basic safety Dual Electrical power Vacuum Electromagnetic CZPTter for Enthusiast
QJZ-2X120&lpar80&rparSF
Perform&colon
It is utilised in underground coal mines&comma the place there are mixed explosive gases this sort of as methane and other coal dust&comma with rated frequency 50hz&comma rated voltage 660&comma 1140V&period It will help to commence and stop the 3-section squirrel cage motor&comma and it can also reverse the path of the motor at the cease&period
Characteristics&colon
It is frequently used for solitary or twin followers surroundings&period The starting up and halting of the two motors can be delayed to reduce the harm to the electricity method&interval It is designed with two different explosion-evidence cavities&comma so that if any mistake happens in one particular cavity&comma it will instantly change to the alternative one&time period Inspection can be accomplished even though fan is functioning&time period
CZPT protection aids to do the parameter adjustment and info inquiry&interval It also guards the electricity technique from electric power leakage&comma lower voltage&comma more than voltage&comma 3-period unbalance&comma overload&comma short-circuit&comma decline of phase and wind electrical power alarm&time period
