    Products Name:S13-mrl triangle core transformer

    Update Time:2017-07-06

    This product has low load loss, low load current, low noise performance, and significant power saving effect. Improve the reliability of voltage quality and power supply, it is the green energy-saving equipment which is beneficial to environmental protection, and the newest product to be used in the urban and rural power grid technology transformation project.

    The S13 - M.R.L, s11-m.r L series full - sealed three-phase coil core transformer is different from traditional planar folding core transformer. The core is composed of a three-phase yoke arranged by a single frame. Each cylinder is continuously coiled by a thin strip of high quality cold rolled silicon steel, and the bandwidth is cut by a straight line or curve by a numerical control open-feed machine. Pick-up at the core of the winding machine winding suborbicular or folding arc frame after processed by vacuum filling nitrogen annealing treatment to eliminate stress, the lattice orientation, improve permeability, improve the electromagnetic properties; Use a dedicated high and low voltage coil winding machine, directly on the core column cylinder winding, the overall structure is compact, solid body using iron yoke insulation and laminated wood, up and down around the screw tighten coil, make it solid, can withstand the impact of sudden short circuit.

    3.1 low dissipation

    According to the current international GB/t6451-1999, the technical parameters and requirements of the three-phase oil immersed power transformer are 30 to 1600kVA, the s13-m.r L series of empty load losses are down 50% on average, and the load losses are down by 30%. The average loss of load loss in the s11-m.r L series was reduced by an average of 25%.

    3.2 low load current

    Because of the excellent quality of the iron core and the characteristics of the winding process, the load current is significantly reduced. According to the current GB/t6451-1999, s13-m.r.l series of no-load current average is down 75%; The s11-m.r.l series no-load current decreased by 75% on average.

    3.3 low running noise

    According to the noise standard of JB/t10088-1999, the noise of s13-m.r L and s11-m.r L was reduced by about 7-9db.

    3.4 strong anti-short circuit capability

    Transformer body as a whole into three-dimensional triangular prism shape, and the central are set around the screw, and the upper and lower iron yoke insulation and laminated wood constitute an organic whole, can effectively resist the sudden short circuit when the axial, radial mechanical stress.
