Product Description QJGZ-800~2400/2~10Mining explosion-proof and intrinsically safe type multi-loop high-voltage vacuum electromagnetic starterApplicationMining explosion-proof and intrinsically safe type multi-loop high-voltage vacuum electromagnetic starter is suitable for coal mine AC 3300V, frequency 50Hz, three-phase neutral point unearthed power supply system, local or remote control of three-phase asynchronous electric drive, to realize the centralized control of shearer, scraper conveyor, crusher, transfer machine, pumping station and other equipment in comprehensive mechanized coal mining face.Technical ParametersModelQJGZ-2400/3300-8, 9, 10QJGZ-1600/3300-6QJGZ-800/3300-4, 2rated operational current2400A1600A800ANumber of output loops8, 9, 1064, 2Vacuum isolation phase changer3 Lines(Each line 800A)2 Lines(Each line 800A)1 Lines(Each line 800A)Shape size including cable connector3100*704*12193100*704*12191605*718*1205Rated operational voltage3300V 50Hzvacuum contactorSingle circuit maximum rated current:400AInput and output modeCable connectorProtection functionLeakage, leakage locking, insulation monitoring, overload, short circuit, overvoltage, undervoltage, phase breakFault queryQuery and store fault information for 30 days at any timeDisplay moduleThe man-machine interface adopts embedded system, and the running condition is monitored dynamically. Communication modeRS485,CAN Bus, EthernetControl modeProximity control, security remote control, network control Technical advantages and functional characteristics1. The combined switch adopts PLC as the core control unit, which has the characteristics of field programmable, extensible input / output points, reliable operation and convenient operation. The man-machine interface adopts embedded industrial control computer, Window ce as operating system, color screen segmentation technology, dynamic display of the running status of the field equipment. 2. The embedded Chinese display system has friendly man-machine interface, convenient and intuitionistic man-machine conversation, "four remote" functions such as telemetry, remote communication, remote control, remote adjustment and so on. It is convenient to realize the unattended working face and achieve the centralized detection and monitoring of the ground dispatching room. 3. The control mode of the combined switch is close control, local security remote control and network control, which can be convenient to start, stop and control the operation mode of independent, program control and double speed, and the control mode is flexible and reliable. 4. The combination switch adopts the quick door opening structure, has the electrical, the mechanical interlocking system, guarantees the power off first, then opens the door. The unit module adopts the integrated module design, the drawer type structure, each circuit has the independent operation mechanism, each corresponding module can transmit the electricity independently and the power off, the module has the built - in commutation mechanism, may realize the commutation function. 5. The switch has the characteristics of small volume, light weight, low power consumption, high sensitivity and convenient installation and use. Reducing the workload of production, installation and maintenance to meet the different needs of users using equipment is an ideal replacement product for digital mines in China.
