Series BQXB explosion-proof inverter | Explosion-proof magnetic starter | Explosion-proof electromagnetic starter 


 First, the scope 
 Zone 1 and Zone 2 dangerous places. 
 IIA, IIB group explosive atmosphere. 



 Second, product characteristics 
 CBQ59 Motor Variable Speed ??Box can change its output frequency to regulate the speed of the ordinary three-phase asynchronous motor, in order to achieve the production process 
 Or to achieve the purpose of saving, the saving rate of 30% -60%, and also can be used as the software of the motor from the controller, sensors, transmitters and control circuit 
 Closed-loop speed control system to install and operate, starting balance the impact of current (soft start), greatly reduce the power capacity, power factor is constant, along with fault indication 
 And other features. 
 1, over-current protection, short circuit protection, overvoltage protection, undervoltage protection, instantaneous power failure protection, and definitely phase protection. 
 2, the figures show that the frequency, speed and load rate or current. 
 3, you can manually adjust the frequency can be set speed time-changing technology curve. Controlled by DCS system signal to its frequency. 
 Of governor of the products imported components. Cabinet is also equipped with ammeter, voltmeter, automatic air switch, indicator light, 
 AC contactor, the frequency-conversion switch and start and stop button. Process according to different user requirements and design, select the device and the preparation of various 
 Appropriate method of operation. 
 4, pipe or cable wiring. 
 5, for GB3836-2000, IEC6007 standard requirements.
