    Shielding Type 250 Kva Transformer / Industrial Transformer With Low Partial Discharge

    Low Partial Discharge SH15-M Type Amorphous Metal Transformer /250KV Shielding Type


    Characteristics of amorphous alloy structure of transformer.


    Amorphous alloys, which are prominent in magnetic properties, are used as core materials to produce transformers, which can be used to obtain very low loss. But it has many features, which must be guaranteed and considered in design and manufacture. The main body embodies the following aspects:


    (1) the hardness of amorphous alloy sheet material is very high, and it is difficult to shear with conventional tools, so the shear amount should be considered in the design.


    (2) amorphous alloy monolithic thickness is extremely thin, the material surface is not very flat, the core filling coefficient is low.


    (3) amorphous alloy is very sensitive to mechanical stress. In structural design, we must avoid the traditional design scheme with iron core as the main bearing structure.


    (4) in order to obtain excellent low loss characteristics, the amorphous alloy iron chip must be annealed.


    Cooling way


    In the operation of the oil-immersed power transformer, the heat of the winding and iron core is first passed to the oil and then passed to the cooling medium through oil. The cooling mode of oil-immersed power transformer can be divided into the following types according to the size of capacity:


    1. Natural oil circulation natural cooling (oil immersed self-cooled)


    2. Natural oil circulation air-cooled (oil-immersed air-cooled)


    3. Forced oil circulating water to cool.


    4. Forced oil circulation to cool.


    Use of environmental conditions

    1. altitude: 1000m;

    2. environmental temperature: upper limit of 5 DEG C 40;

    3. relative humidity: the relative humidity of air is not more than 95% (25 degrees C);

    4. there is no strong turbulence, vibration, and the environment that is not more than 15 degrees with the inclination of the vertical plane.

    5. can be used in the air containing methane and coal dust at the risk of explosion, but not enough to corrode metal and to destroy the insulated gas and steam.
