    Features of Products

    As one kind of distributing transformer for mining use. KS9 series transformer has many advantages, such as compacted body, reasonable structure, lOW in spoilage, good in heat-dispersion and, easy to go into a well.
    This series of product adopt high-permeance cold-rolled grain-oriented silicon- steel plate of high-quality. The iron core applies echelon form iterative accumulation. The core pole which is multileveI circular cross-section can ensure of low noise and low spoilage. The structure of gasoline tank is very firm. Both side of tank are welded with cable lunction boxes of high and low voltage which are used for wiring. High-voltage loops need tapping voltage that is 15% of rated voltage. It is using the tap switch to change the voltage. When the voltage exchanges, the power must be cut off fist, then unveil the wind-rain cover on the tap switch to counterchanqe the voltage. The low voltage side of the transformer can be connect the type ‘Y’ of 693V or the type“D”of 400V to supply power. And inside the cable iunction box has a secondary terminal which educes six insulators for users’ option. The ioint hinges that welded on the casing are available and drawing crow-plate is mounted beneath the base. There are mounting holes in the drawing crow-plate used for being addly-installed with mine-car’ contact roller whenmine needing.

    Practicable Confiners

    The oil-immersed distributing transformer is applied to the capacity 630KVA or below, and the voltage 10KV or below. This product is normal one which has no requirement of explosion-proof. The main function of the product is for mine illumination when distributing power for mining as well as for the driving power. This series of transformers will not need lift-machine examination after transportation. It is allowed to assemble the unshipped spare pads for checking and acceptance.

    Comply Standards

    Standards for this series of product:
    GB1094.1~2-2005、GB1094.3,5-2005、GB/T6451-2015、GB/T12173-2008.

    Using environment and working conditio

    1、The installment highly does not surpass elevation 1000m, the special environment gives the explanation in addition
    2、Amblent temperature:

    • Highest air temperature+40℃;
    • Highest daily average air temperature+25℃;
    • Highest annual average air temperature+20℃;
    • Lowest outdoor air temperature-20℃.

    3、The surrounding air relative humidity is not bigger than 95%(+25℃ when)
    4、Installs under the mine pit although has the coal dust, the gas, but non-explosion hazard plare;
    5、The supply voltage profile is approximate to the sine wave;
