Mining explosion-proof and intrinsically safe type multi-loop vacuum electromagnetic starter
Application
This equipment is applicable to a mine containing explosive dangerous gas and coal dust. In the line of 50 hz and the rated voltage of 1140v (660v), the starting and stopping of the three-phase squirrel-cage asynchronous motor shall be controlled and protected at the same time. And the phase sequence can be changed at the time of the stop. And is especially suitable for centralized monitoring of the working surface with more concentrated power load such as mining, transportation, coal mining and the like.
Technical Parameters
Technical advantages and functional characteristics
1. Can complete motor overload, short circuit, overvoltage, undervoltage, phase break, leakage current locking, gas locking, wind power locking power measurement, communication networking protection functions.

Technical advantages and functional characteristics
1. Can complete motor overload, short circuit, overvoltage, undervoltage, phase break, leakage current locking, gas locking, wind power locking power measurement, communication networking protection functions.
2. The combination switch housing is cuboid and adopts quick door opening structure. It has reliable mechanical interlocking and electrical interlocking system.
3. Siemens PLC is used as the core control unit, which has field programmable and extensible input / output points. The network communication can be carried out conveniently, and the networking function is powerful. It has the functions of telemetry, remote communication, remote control and remote adjustment. It is convenient to realize the unattended working face and to achieve the centralized detection and monitoring of the ground dispatching room.
4. The Chinese display system can set the parameters of the combination switch and the single machine, the two machine and the double speed (including the single machine and the double speed, the double machine and the double speed) and so on, and has the display and memory function of the working state and the fault type. With friendly man - machine interface, the efficiency of judging and troubleshooting is greatly improved.
5. The pilot circuit of the combination switch is intrinsically safe, which can effectively prevent the occurrence of spontaneous starting accidents caused by short circuit or grounding of control line.
6. With multiple modes of operation (near control, remote control, network control) and multiple control modes (independent control, program control, double speed control, mixed control)
