      Energy-saving and efficient: Adopt high-efficiency transformers and intelligent control systems to reduce energy consumption.

      2. Structural composition

      Mine pre-installed mobile substations usually consist of the following components:

      High-voltage switchgear: used to receive and distribute high-voltage electrical energy, with protection and control functions.

      Transformer: Converts high-voltage electrical energy into low-voltage electrical energy, usually using a dry-type transformer or an oil-immersed transformer.

      Low-voltage switchgear: used to distribute low-voltage electrical energy to mining equipment.

      Protection device: including relay protection, lightning arrester, grounding device, etc., to ensure the safety of the system.

      Control system: PLC or microprocessor is used to realize automatic control and remote monitoring.

      Shell structure: Adopt a solid metal shell, with dustproof, waterproof, explosion-proof and other functions, to adapt to the harsh environment of the mine.

      Mobile base: Equipped with trailer or slide rails for easy transportation and movement.

      3. Technical characteristics

      Modular design: Each functional unit is modular, which is easy to transport, install and maintain.

      Rapid deployment: Pre-assembled design reduces on-site installation time and can be put into operation quickly.

      Strong adaptability: The shell has a high protection level, and is suitable for harsh environments such as high temperature, high humidity and dusty mines.

      Intelligent control: support remote monitoring and automatic operation to improve operational efficiency.

      High reliability: It has multiple protection mechanisms to ensure the safety and stability of power supply.

      4. Fields of application

      Mine prefabricated mobile substations are mainly used in the following scenarios:

      Mining: Provide power supply for open-pit mines and underground mines.

      Temporary power supply: Used for temporary power needs in the newly mined area of the mine.

      Emergency power supply: Provide backup power in the event of a power failure to ensure mine production.

      Power supply for mobile equipment: Provide power support for mining mobile equipment (e.g., excavators, conveyor belts).

      5. Advantages

      Flexible and efficient: Move and deploy quickly to adapt to changes in the mining area.

      Cost savings: Reduce on-site installation time and expenses, and reduce overall investment costs.

      Safe and reliable: It has a perfect protection mechanism and adapts to the harsh environment of the mine.

      Energy saving and environmental protection: Adopt high-efficiency transformers and intelligent control systems to reduce energy consumption and carbon emissions.

      6. Technical parameters

      Rated voltage: 6kV/10kV/35kV on the high-voltage side and 0.4kV/0.69kV on the low-voltage side.

      Rated capacity: typically a few hundred kVA to several MVA.

      Degree of protection: Enclosures are usually IP54 or higher for harsh environments.

      Operating temperature: 20°C~+45°C.

      Mode of movement: trailer type or slide rail type, easy to transport.

      The pre-installed mobile substation for mining is an efficient, flexible and reliable power supply equipment designed for the mining environment. Its modular design, rapid deployment and high adaptability make it an important solution for mine power supply, which can meet the power needs of the mining area and ensure the continuity and safety of mine production.

      Product structure features

      The substation is composed of a high-voltage room, a transformer room and a low-voltage room, which can be arranged into a mesh type or a product type;

      With terminal, ring network or dual power supply mode:

      It can be made into a single or double transformer power supply scheme:

      Oil-immersed power transformers and dry-type power transformers are available:

      The box is equipped with sufficient natural vents and thermal insulation measures to ensure the normal operation of all electrical equipment (forced cooling can be used according to user needs): the "five prevention" functions are complete, the operation and maintenance are convenient, and the operation is safe and reliable:

      The shell material is stainless steel, aluminum alloy, cold-rolled plate, color steel composite plate, non-metallic or a combination of the two, which is anti-aging, flame retardant and anti-corrosion.

      Waterproof, dustproof, with long-term outdoor use conditions;

      Small size, light weight, beautiful appearance and environmental coordination: when the SF6 load switchgear is selected, the overall size of the box transformer is small, which is more suitable for community construction and street lamp engineering transformation. o The high-voltage ring main unit can assemble the network automation terminal (RTU) to achieve reliable detection of short circuit and single-phase grounding fault, with "four" functions, which is convenient for the automatic upgrade of distribution network.
