KBSG Mining Explosion-proof Dry Type Transformer

Summarize:

    This series of products can be used in the mine with hazard of explosion due to methane gas and coal-dust, as the distribution equipment of underground mining mechanical equipment.

Technical Parameter:

Rated voltage

    Primary voltage: 6kv, 10kv

    Secondary voltage: 400v, 693v, 1200v, 3450v

Rated capacity: 50, 100, 200, 315, 400, 500, 630, 800,1000, 1250, 1600, 2000, 2500,3150, 4000(KVA)

Explosion-proof form: mining flameproof Exdl

Use environmental conditions:

Altitude: should be less than 1,000 meters

Environmental temperature

    The highest temperature: +40℃

    The highest average temperatures: +40℃

    The highest annual average temperature: +20℃

    The lowest temperature:-20℃

Relative humidity of the air does not exceed 95% (+25℃ )

    In the mine with methane gas mixture,coal-dust and explosion danger

Environment without severe turbulence, vibration, the vertical inclination less than 15°

    Without gas and steam which corrode metal and destroy insulation.

    The power supply voltage waveform approximates sine wave.

    Three-phase power supply voltage approximate symmetrical.

Product characteristic:

    The iron core use high-permeability and high quality cold rolled steel sheet, small juncture, low dissipation, little noise;

    Using new materials, the line between layers, the turn-to-turn using Du Pont NOMEX - 410 insulated material, heat-resisting class H;

    Coil vacuum leaching paint. Coil impregnation paint fully permeate deep, 160-170℃ drying curing, high mechanical strength;

    Transformer body vacuum drying. The body surface covered by a layer of damp- proof and corona –proof paint, has good insulation performance;

    The high and low voltage sides use microcomputer integrated protection,  realize the double protective function, have protection to short circuit, over-current, leakage, overvoltage and undervoltage, and realize PLC control and man-machine dialog functions.
