        500kva mining subsationPurpose
        The product is suitable for underground environment containing methane mixture gas and coal dust with potential explosion hazard. There are two groups of three-phase power supplies (which have same output voltage and 30°phase difference) at the secondary side, will work as the power supply for the converter 12-pulse rectification. It is suitable for coal mine, nonferrous metal mine, tunnel engineering, etc.


        Characteristics
        The product is mining flame proof type, and it has excellent flame-proof performance and adequate mechanical strength.
        The transformer is designed with free assembling core structure to prevent the product internal loose during transportation.
        High endurance on thermal shock, ultra-highly load and anti-short circuit; low loss, low partial discharge, good insulation performance.
        No sensitive to temperature and dust. Nonflammable, fire-retardant, no harmful gas, low noise and no pollution.
        Easy to operate and maintain. High insulation, can withstand the harmonic over-voltage insulation impact.
        High harmonic inhibiting ability, effectively limits 5 or 7 times harmonic current by 12-pulse phase shifting function.
