    Product Details

    S □-M Series Oil-immersed Fully Sealed

    The S□ -M series three-phase oil-immersed transformer adopts a fully oil-filled, sealed corrugated oil tank. and the oil tank shell adapts to the expansion performance of the oil with its own elasticity and meets the heat dissipation requirements. It has the characteristics of high efficiency and low loss, which

    can save a lot of power consumption and operating costs, and is widely used in power plants, substations, industrial and mining enterprises, ports, airports and other environmental protection places.

    Standard: IEC60076-1, IEC60076-2, IEC60076-3, IEC60076-5, IEC60076-10.

     Structure

    1

    Iron core:

    ● The iron core is made of high-quality, high-performance, high-permeability silicon steel sheet,with low no-load loss.

    1

    High/low voltage winding:

    ● The low-voltage winding of 500KVA and below is a layer type, and the new spiral type is used for 630KVA and above.

    ● It  has  the  characteristics  of  high  mechanical  strength,  balanced  ampere  turn distribution, and strong short-circuit resistance.

    1

    ■  Fully sealed structure:

    ● The product is a fully sealed structure. The vacuum oil filling process is used for the  transformer   packaging,  which   completely  removes  the   moisture  of  the transformer, ensures the  isolation  of the transformer  oil from the  outside  air, prevents  the  aging  of  the  oil,  and  improves  the  operation  reliability  of  the transformer.

    1

    ■  Positioning structure:

    ● The  product  body  has  added a  positioning  structure to  prevent  displacement during  transportation,  and  all  fasteners  are  equipped  with  fastening  nuts  to ensure  that  the  fasteners  do  not  loosen  during  long-term  operation  of  the product.

    1

    ■ Oil tank:

    ● The  oil  tank  adopts  a  corrugated  oil  tank.Simple   process,   high  mechanical strength,good welding effect,not easy to leak,due to the strong fluidity of the oil, the heat dissipation capacity of the product is improved.

     

     

    ■ Other configuration:

    ● Equipped  with  pressure  relief  valve,  signal  thermometer,  ensures  the  safe operation of the transformer.

    Note 1:for transformers with rated capacity of 500kVA and below, the load loss values above the diagonal line in the table are applicable to the Dyn11 or Yzn11 coupling group,and the load loss values below the diagonal line are applicable to the Yyn0 coupling group.

    Note 2:when the average annual load rate of the transformer is between 35% and 40%, the maximum operating eficiency can be obtained by using the loss value in the table.
