Mining Explosion-proof Vacuum Feeder Switch
Mining Vacuum Feeder Switch equipped with high-performance PLC Vacuum Feeder Switch that dedicate to serve the feeder switch to protect and monitor. The product has various protection functions such as overload, short-circuit, leakage interlock, leakage protection, under voltage, over voltage, three-phase imbalance, gas interlock, interlocked circuit breaker, selective leakage protection, three-phase balanced protection, long distance short-circuit protection, communication networking. Our Intrinsically Safe Vacuum Feeder Switch is also available.
Square switch with quick-actuating closures structure.
The whole structure is small and nice. The switch is equipped with quick plug-in connection and the technology is simple and direct
Powerful function of communication network
Standard RS485 interfaces are equipped with the device. Seamless joint field device can be realized. That makes it convenient to establish site monitoring system. The product has “4T” (telemeter, telecommunication, telecontrol and teleregulation) functions and it is easy to access substations underground and merge into industrial Ethernet. Concentrated monitoring in ground control center now is available.
Intelligent man-machine system
Intelligent protection and control are applied to the product. Human-computer interaction interface is displayed by Chinese on color LCD. Pull-down menu makes it simple and direct to operate.
Real-time display of parameters
Many sorts of information are displayed while the device is running, such as current time, three-phase current, grid voltage, active power, power factor, insulation resistance, main/branch switch, running condition, temperature, gas concentration, interlocked circuit breaker, etc.
Function customization
Man-machine visual operation can be realized through operation panel on the front door. Parameters of the equipment can be set, modified, corrected and inquired. Different functions can be customized according to different demands and corresponding protection function can be selected and shut.
Simulated experiments
The product has simulation experiment functions of leakage and short-circuits faults. Experiments can be done through operation panel on the front door.
Self-check, memory, display and inquire of device faults
The product has self-checking function of software and hardware and functions of memory, display and inquire of device faults. Details of recent 100 errors can be recorded and maintenances are more convenient.
