FGI Shanghai Temple long distance power supply comprehensive treatment device safe operation for one year

The Great Wall Six Mine is a mine in Shanghai Miao Economic Development Zone, Etoke Front Banner, Inner Mongolia. The mine received the title of "Sun Cup" in September 2012. The annual designed production capacity of the coal mine is 1.5 million tons, and the existing raw coal reserves are 135 million tons, which has good stability and good continuity. Shanghai Miao mining area is mainly mined 3, 5, 9 coal, which is a more ideal coal seam.

The Great Wall Six Mine firmly established the "light assets, fine labor, low cost, high efficiency" business philosophy, adhere to innovation, innovation as the soul, adhere to innovation and optimization, consolidate the development advantages, the underground system was subverted optimization, put forward "2 fully mechanized mining face, 3 excavation head, underground workers 300 people, and strive to per capita 10,000 tons" long-term production mode positioning, Strive to create a "safe, efficient, green, smart" type of modern mine.

FGI has now completed the first anniversary of the long distance power supply comprehensive treatment equipment for the driving face of 1501 N Shangmiao Mining area in Inner Mongolia. The back-end load is mainly 260 kW, EBZ260 type roadheader. This is the company's third and fifth working face in the Shanghai Miao mining area.

FGI long distance power supply integrated treatment device, through the combination of reactive power and cable voltage drop control, can quickly perform voltage compensation, and can effectively improve the power factor. The 1140 V products produced by the company can automatically compensate the pressure drop of the cable according to the length of the cable, and reach the remote power supply of 3,000 meters of the driving face.

This project will fundamentally solve the problem of direct power supply voltage drop caused by equipment operation and start-up, prevent equipment startup failure or instability caused by voltage drop and other problems, so as to break through the bottleneck of coal production industry development, use reactive power compensation, improve the power supply factor of roadway working face, and achieve the purpose of energy saving and emission reduction.

It is of great significance to increase coal production, reduce production cost and enhance the reliability of power supply. In addition, by improving the traditional coal mining operation process, the number of underground workers has been greatly reduced, the labor intensity of workers has been effectively reduced, and the work safety has been further improved.

After the device is used in the mine driving and coal mining face, the power supply distance between the mobile transformer and the post-load equipment can be extended from the current 1000 m to 5000 m, which solves the problem of frequent displacement of the transformer equipment due to the low terminal power supply voltage, reduces the labor intensity of the mine driving and coal mining face, and improves the work efficiency.

Through automatic adjustment of reactive power, the compensation of reactive power, reactive power and harmonic is realized, the power supply quality is improved, the electrical equipment is protected, the failure rate is reduced, and the power factor is more than 0.95. To achieve the purpose of energy conservation, it is expected to save 1.2 million yuan of labor costs for laying cables and moving distribution points, save about 400,000 yuan of investment in cable and power equipment, and reduce downtime, and increase the average efficiency of each person by about 20%.

The successful and reliable operation of the FGI long-distance power supply comprehensive treatment device proves that this technical solution can be applied to all coal mines at home and abroad, including coal mines with high remote power supply requirements, and can also be promoted on a large scale in other mining enterprises in China to improve the efficiency of the existing mining production technology, and has a wide range of market promotion and application prospects.

FGI long distance power supply comprehensive treatment device

FGI has served the coal mining industry for more than 30 years, providing five series of products and services of "less electricity, good use of electricity, renewable electricity, storage electricity, explosion-proof electricity", among which the newly developed long-distance power supply device and energy storage inverter fill the domestic gap. In recent years, with the promotion of the national strategy of the Belt and Road, FGI long-distance power supply devices have been going out of the country, serving various long-distance power supply sites in more than 10 countries and regions such as Russia, Laos and Serbia. Adhering to the development concept of "unlimited green electricity", FGI uses safe and efficient power supply system solutions to implement the Belt and Road strategy and accelerate the international layout.
