Flameproof and intrinsically safe dual power vacuum electromagnetic starter QJZ-2x120(80)/1140(660)SF for coal mine fan


Suitable for coal mine in explosive environment, in rated frequency 50Hz, rated voltage 1140V, 660V, rated current up to 120A and below the power supply system, directly or remotely to three-phase AC asynchronous motor or AC double-winding two-speed motor to start, stop, forward and reverse rotation, two-speed switching; In addition, it can automatically switch the main and backup fans in case of failure or power failure, and protect the power supply line of the motor. The product is aimed at the anti-rotating fan or one-way machine used in the coal mine to realize the dual fan and dual power supply on the mining face, and the fan automatic switching device mainly for the fan. It adopts dual intelligent comprehensive protection and control. Because the electromagnetic starter is designed as an integrated two independent flasproof boxes, it can realize non-stop maintenance or multi-machine joint control.

Flameproof and intrinsically safe dual power vacuum electromagnetic starter for coal mine fan (high-end intelligent series) QJZ-2x120/1140(660)SF


Suitable for coal mine in explosive environment, in rated frequency 50Hz, rated voltage 1140V, 660V, rated current up to 120A and below the power supply system, directly or remotely to three-phase AC asynchronous motor or AC double-winding two-speed motor to start, stop, forward and reverse rotation, two-speed switching; In addition, it can automatically switch the main and backup fans in case of failure or power failure, and protect the power supply line of the motor.The product is used in coal mine underground for rotating fan or ChanXiangJi, realize the tunnelling face double fan double power supply, mainly for the fan fan automatic switching device, it adopts double intelligent integrated protection control, due to the design of electromagnetic starter as well the two separate flame-proof box, can not achieve down or more machine from spreading.
