FGI (SH688663) has a comprehensive layout of the mine explosion-proof electrical product chain, with more than 50 years of power electronics R & D and manufacturing experience, and is committed to providing multi-scenario mine electrical "safety + energy saving" solutions.
Explosion-proof type definition
Generally, for the use of products or equipment in flammable and explosive dangerous places, it is necessary to pass the national authoritative certification body in accordance with the explosion-proof standard GB/T3836-2021 to test and issue a qualified explosion-proof certificate before it can be used. The letters in the explosion-proof mark represent the following meaning:
Explosion-proof form letters (such as i, d, e, etc.) : Indicates the explosion-proof form of the device. For example, i represents intrinsically safe electrical equipment, d represents flameproof electrical equipment, e represents increased safety electrical equipment, etc. These explosion-proof forms are determined according to the structure, material and circuit characteristics of the equipment to ensure that it will not cause an explosion when used in an explosive environment.

Flameproof and intrinsically safe inverter for mine use
Explosion-proof variable frequency speed regulation is a kind of high efficiency and high performance speed regulation, through the control of asynchronous motor (or synchronous machine), to achieve stepless smooth speed regulation, to meet the requirements of various production machinery, the use of variable frequency speed regulation in coal mines has become the trend of mining equipment speed regulation.
Mine flameproof and intrinsically safe SVG
Explosion-proof and inherently safe static reactive power generator (explosion-proof SVG for short) for mine can rapidly and continuously provide capacitive or inductive reactive power. It adopts advanced instantaneous reactive power theory and power decoupling algorithm based on synchronous coordinate transformation to dynamically track power quality changes of the power grid with the set reactive power nature and size, power factor and grid voltage as control targets. Adjust reactive power output, and can realize curve setting operation, improve power factor, balance three-phase voltage, suppress voltage flicker and voltage fluctuation, control harmonic pollution, etc., completely solve the power quality problems of coal mine underground power supply system.
Flameproof and intrinsically safe voltage terminal compensator for mine use
Our company proposes an innovative comprehensive regulation device for underground voltage. This device can realize reactive power compensation of underground power supply system, improve the power factor of the power supply system, reduce the cable voltage drop loss caused by reactive power loss, and at the same time, adopt a compensation scheme to raise the voltage of the power supply system for the cable loss caused by active current. It can then compensate the cable voltage drop loss caused by the active current of the system, perfectly solve the problem of low voltage of the long distance end motor and stabilize the end voltage of the power supply grid. Theoretically, it can ensure that the voltage compensation of the end voltage of the underground long distance power supply grid can reach 97% of the rated power grid voltage when the equipment is started. The grid voltage value can be compensated to 99% of the rated grid voltage during full load operation.
