Product Description

Product Description
Product introduction
S13-MRL series Three-phase solid coil core power distribution transformers break through the traditional plane structure layout, using three-phase symmetrical three-dimensional structure. Because there is no air gap in the magnetic circuit and the winding is closer, the magnetic direction of the silicon steel strip is completely consistent with the magnetic circuit direction, the three core columns are arranged in an equilateral triangle three-dimensional arrangement, the three-phase magnetic circuit length is the same, and the product noise is low, which is  energy-saving  distribution transformer at present.

 Product features
a. three phase balance and harmonic current are small. The three cores have the same length of magnetic circuit, the same magnetic resistance, and the three phases are completely balanced, so they have the characteristics of very low harmonic current
b. low no-load loss, no-load current and noise
c.special automatic winding machine to ensure coil quality
d. inner positioning structure is adopted for winding to effectively protect core and ensure core loss
 

Structural features

1.S13-M- transformer core: the use of material properties of not less than 30ZH120 cold-rolled silicon steel; three-phase three-column three-dimensional

symmetrical structure of the most balanced three-phase magnetic circuit; each group (volume) In dedicated iron Heart winding machine on the system, the pressure

evenly compact; core frame by vacuum annealing treatment to eliminate stress, improve electromagnetic performance; core surface coated with epoxy paint, moisture,

curing.

2.S13-M- transformer windings: the use of low-oxygen copper material paper drum flat wire or QQ-2 acetal enamelled round copper wire; low voltage coil for the

double or four round copper or new spiral, Or foil. High voltage line Ring for the multi-layer cylinder; coil oil for the corrugated structure, interlayer insulation for the

double-sided adhesive tape; low pressure and high pressure surface are added around the epoxy resin semi-viscous fiberglass belt, increase the mechanical strength.

3.S13-M- transformer body, leads: the use of insulating cardboard made of upper and lower iron yoke insulation; the use of laminated wood production balance pad

insulation; the use of laminated cardboard for the lead bracket; all fasteners are Effective locking nuts.

4.S13-M- transformer oil tank: the use of triangular structure of the whole sealed corrugated fuel tank, three-phase are set to provide heat dissipation and

compensation with the oil temperature changes caused by changes in the volume of oil volume expansion; The oil level gauge with pressure relief valve on the cover is

easy to refuel and observe the oil level, and the pressure protection is safe when the internal fault of the transformer is overvoltage.

Main technical parameters

Note:

For rated capacity for 500 kVA and below transformers,above the diagonal values of loss of load application in Dyn11 connection group,below the diagonal load loss value appliacble to Yyn0 connected node.
