                                                Mining Explosion-proof  Vacuum Feeder Switch

1. Introduction

The product equipped with high-performance PLC 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, overvoltage, three-phase imbalance, gas interlock, interlocked circuit breaker, selective leakage protection, three-phase balanced protection, long distance short-circuit protection, communication networking. The product equips colorful man-machine interface and easy to established in network. Stable performances, sensitive protection, reliable reactions and high protection  precision make the product become a perfect upgrade product for domestic mine digitization.

2. Excellent performance, ideal choice.

* 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.

* 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 protection and control are applied to the product. Human-computer interactioninterface is displayed by Chinese on color LCD. Pull-down menu makes it simple and direct to operate.

* 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.

* 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.

* The product has simulation experiment functions of leakage and short-circuits faults. Experiments can be done through operation panel on the front door.

* 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.

* The PLC feeder switch is the best one of domestic similar products and has reliable protection function and fast response speed. "Main-branch-branch" three levels selective leakage protection can be realized and delay time is continuously adjustable. The switch will trip and record the examining reports meanwhile finding the location of leakage in 30ms.
