Low Voltage Distribution Cabinet, Metal Distribution Box, Power Distribution Board, Electrical Enclosure Cabinet

It is suitable for three-phase AC 50Hz, rated voltage 690V and below, rated current 4000A and below, in three-phase four wire system or three-phase five wire system and other power systems, used for power conversion, distribution and control. 

Mining general low-voltage switchgear can be used as a complete set of low-voltage power distribution equipment in the 690V and 400V power supply system of substations in underground coal mines, underground yards without gas and coal dust explosion hazards, workshops with heavy dust corrosion, and wet places of metallurgy, subway and low buildings. 

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 comprehensive protection device for mining belt conveyor is a safety protection system used for belt conveyors (belt conveyors) in mining industries such as coal mines and metal mines. It aims to monitor the operating status of the belt conveyor in real time, prevent faults, and ensure the safety of personnel and equipment

It is suitable for the mine with explosive dangerous gas and coal dust. It can control and protect the start and stop of less than 4 three-phase squirrel cage asynchronous motors in the AC 50 Hz and rated voltage ac1140v (660V), and the phase sequence can be changed when stopping. It is especially suitable for the centralized monitoring of mining, transportation, coal mining and other dynamic loads.

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.

This soft starter is suitable for coal mines containing explosive gas (methane) and coal dust. In AC 50Hz, voltage 1140V or 660V, neutral point ungrounded power supply system, perform various forms of soft starting (such as current limit, voltage ramp and power torque ramp for three-phase squirrel cage motors with currents below 200A and 400A) ) . It also has perfect protection function and fault display function, which greatly reduces the troubleshooting time.

The permanent magnet synchronous motor adopts centralized winding, optimal pole slot coordination, and rotor structure integrating isolation, stress, positioning and lightweight, with small rotational inertia, small leakage flux, large main flux, higher power factor and higher efficiency.
