Mine Explosion-Proof and Intrinsically Safe Multi Circuit High Voltage Vacuum Electromagnetic Combination Switch

QJZ3-2400/1140(660)-8ML  mine explosion-proof and intrinsically safe type multi-loop  vacuum electromagnetic starter , it is applicable to the mine with explosive gas and coal dust. In the circuit with AC 50Hz and rated voltage of AC 1140 (660) V, it can control and protect the starting and stopping of 8  or less three-phase squirrel cage asynchronous motors at the same time, and can change the phase sequence when stopping. It is especially suitable for centralized monitoring of mining, transportation, mining and other working faces with concentrated power load.

Mining 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.

Mining Intrinsically Safe Velocity Sensor for Belt Conveyor. Model: GSC5000(B).

The product is mainly applicable in the coal mine with explosive gas (methane mixture), to control, protect and measure in the three-phase AC neutral point not directly grounded power supply system of rated voltage 10KV, 6KV, rated frequency 50Hz.

KJS series mine pneumatic wet dust precipitator is designed to be suitable for dust removal in gas discharge drilling holes, Tunnel Shotcreting, tunnel driving, etc. the dust precipitator is placed next to the drilling machine and shotcreting mixer, the roadheader body, the second transport belt, or the place designated by Party A, and the underground high-pressure water pipe is connected to the filter inlet. The filter outlet is connected to the inlet joint of the dust precipitator through the high-pressure rubber pipe, and the compressed air is connected to the air inlet. Open the high-pressure water valve and air pressure valve for operation.

The soft starter is suitable for coal mines containing explosive gas (methane) and coal dust.In an AC 50Hz, voltage 1140V or 660V, neutral ungrounded power supply system, various forms of soft start (such as current clipping, voltage ramp and power torque ramp) are performed on three-phase squirrel-cage motors with currents up to 200A and 400A.The controller also has the perfect protection function and the fault display function, greatly reduces the time of troubleshooting.
