Audited Supplier S13 three-dimensional coil core transformer is a kind of core transformer, with low no-load loss, low no-load current, low noise performance, power saving effect is remarkable.
3.1 Low loss
According to the current international GB/T6451-2015 "Three-phase oil-immersed power transformer technical parameters and requirements" capacity 30-1600kVA, S13-M.L series no-load loss decreased by an average of 50%, load loss decreased by an average of 30%; The average no-load loss of S11-M.LS series is reduced by 30%. The average load loss is reduced by 25%.
3.2 Low no-load current
Due to the excellent material of the coil core and the characteristics of winding processing, the no-load current is significantly reduced. According to the current national standard GB/T6451-1999, S13-M.L series no-load current decreased by 75% on average; The average no-load current of S11-M.LS series is reduced by 75%.
3.3 Low running noise
According to JB/T10088-1999 noise standard, the noise of S13-M.L and S11-M.L series is reduced by about 7-9dB.
3.4 Strong short-circuit resistance
The transformer body as a whole into a three-dimensional triangular prism shape, all around and in the center are set up pull screw, with the upper and lower iron yoke insulation and laminated wood to form a body, can effectively resist the sudden short circuit of the axial and radial mechanical stress.
4.1 Iron Core
The material performance is not less than 30ZH110 cold rolled silicon steel sheet; Three-phase three-column three-dimensional symmetrical structure has the most balanced three-phase magnetic circuit; Each group (coil) core is wound by thin steel strip on a special core winding machine, and the pressure is uniform and tight; The core frame is annealed by vacuum to eliminate stress and improve electromagnetic performance. Core surface coated with epoxy resin paint, moisture-proof, curing.
4.2 Winding
The use of low-oxygen copper paper-covered copper flat wire or QQ-2 acetal enamelled round copper wire; The low voltage coil is double or four layer round copper type or new screw type or foil type. The high voltage coil is multi-layer cylinder type; The coil oil passage is of corrugated structure, and the insulation between layers is double-sided dotting paper. The low pressure and high pressure surfaces are wrapped with epoxy resin semi-viscous glass fiber tape to increase mechanical strength.
4.3 Body and lead
The upper and lower iron yoke insulation is made of insulating cardboard; Laminated wood as a balance pad insulation; Laminated cardboard is used as lead support; All fasteners are effectively locked locknuts.
4.4 Fuel Tank
The triangular structure of the fully sealed corrugated oil tank is adopted. The three phases are provided with corrugated sheets to ensure heat dissipation and compensate for the change of oil volume due to the change of oil temperature. An oil level gauge with pressure relief valve is installed on the cover of the tank to facilitate refueling and observation of the oil level height, and to protect the release of pressure in case of sudden fault overvoltage in the transformer.

Application Scenarios
The series of fully sealed three-dimensional three-phase coil core transformer produced by the company is different from the traditional flat laminated core transformer. The core is composed of a three phase yoke arranged by a single frame piece three-dimensional triangle. Each cylinder is continuously rolled by a high-quality cold rolled silicon steel strip, and the bandwidth is cut straight or curved by a CNC cutting machine. The tape material is wound on the core winding machine to form a nearly round or flanged arc frame sheet, and is then annealed with vacuum nitrogen to eliminate the processing stress, reorientation of the lattice, improvement of magnetic permeability, and improvement of electromagnetic performance: The high and low pressure wire is wound directly on the core column paper tube using a special winding machine, the overall structure is solid and compact, the body is made of upper and lower iron bar insulation and laminated wood, and the screw is pulled around to tighten the coil. Make it stable and reliable, can withstand the impact of sudden short circuit.
