KSG Mining Mobile Substation
The KSG Series (including the KBSGZY flameproof model) Mining Mobile Substation is a high-end, fully integrated mobile power distribution system specifically designed for coal mines, metal mines, and tunnel construction projects. This equipment employs a "three-in-one" modular design, seamlessly integrating a high-voltage vacuum switch (incoming line control), a dry-type transformer (voltage step-down), and a low-voltage protection cabinet (outgoing feeder) onto a single, heavy-duty steel base. The system supports incoming voltages of up to 10kV with a rated capacity reaching 4000kVA; it features a fully enclosed, explosion-proof structure, exceptional vibration resistance, and robust maintenance-free operation. Capable of being deployed directly into active mining faces, it delivers safe, continuous, and intelligent power transmission to modern, fully mechanized mining machinery.
Description
Technical Advantages
1. Highly Integrated “Three-in-One” Design:The transformer, high-voltage vacuum switch, and low-voltage feeder protection cabinet are modularly assembled; comprehensive interlocking tests are completed prior to shipment, ensuring a “plug-and-play” solution that is ready for immediate use upon unpacking.
2. Robust Dual-Layer Flameproof Protection:Features a fully welded, sealed enclosure constructed from specially reinforced alloy steel plates. This design meets stringent mining-specific flameproof standards, enabling reliable operation in hazardous environments containing flammable and explosive gases, such as methane or coal dust.
3. PLC-Based Intelligent Comprehensive Protection: The core control system integrates an industrial-grade PLC with an LCD Human-Machine Interface (HMI). It provides a full suite of intelligent microprocessor-based protection functions, including safeguards against overload, short circuits, ground faults (with interlocking), phase loss, over-temperature, and interlocking with ventilation and methane monitoring systems.
4. Skid-Mounted Design for Rapid Relocation:The unit features a specialized heavy-duty base equipped with either sliding skids or rail-mounted wheels. This allows the entire substation to be towed and relocated by a traction vehicle as the mining face advances, reducing deployment time by 80% compared to traditional fixed substations.
5. Superior Energy Efficiency and Environmental Friendliness:The transformer core is constructed from high-permeability, cold-rolled silicon steel sheets featuring a full-oblique, step-lap structure. This is encapsulated using H/C-class, highly flame-retardant insulating materials, resulting in low no-load losses, minimal noise emission, and an eco-friendly, pollution-free operation.
Application Scenarios
1.Underground Mechanized Mining and Excavation Faces: Provides proximate, highly reliable power supply for high-power coal shearers, roadheaders, scraper conveyors, and belt conveyors.
2. Metallic and Non-metallic Mines (Iron, Copper, Gold, etc.): Underground central substations, shaft bottom stations, main intake airways, and other extremely harsh environments characterized by high humidity and heavy dust.
3. Underground Road, Railway, and Water Diversion Tunnel Projects: Provides temporary or phased high-voltage step-down power supply for large-scale mobile construction machinery, such as shield tunneling machines and jumbo drill rigs.
