Product overview

Resin insulated three-dimensional triangular wound core dry-type transformer adopts three-dimensional triangular wound core core components. After assembly and annealing, the three-phase magnetic circuit is completely symmetrical, the magnetic resistance is greatly reduced, and the excitation current and no-load loss are significantly reduced.
In addition to the advantages of conventional dry-type transformers such as safety and strong overload capacity, the resin cast three-dimensional wound core dry-type transformer also has the characteristics of environmental protection, no-load loss, small excitation current, low noise, moisture-proof, anti-corrosion, strong short-circuit tolerance, and resistance to It has the characteristics of good impact overvoltage performance, small size, light weight and beautiful appearance.

The main performance indicators of the products are better than domestic standards. It is most suitable for use in environments with high fire protection requirements, such as high-rise residences, airports, stations, docks, subways, hospitals, power plants, metallurgical industries, shopping malls, densely populated areas, petrochemical industries, nuclear power plants, nuclear submarines and other places. The new high-tech transformer product, the resin-cast three-dimensional wound core dry-type transformer, provides a new value-added transformer solution that is energy-saving, environmentally friendly, moisture-proof, anti-corrosion, has strong short-circuit tolerance and strong impulse overvoltage tolerance.

Model and features

Structural features

● Remarkable energy-saving effect: The three-dimensional triangular rolled iron core has no seams, that is, there is no high energy consumption area. It can give full play to the high magnetic permeability characteristics of high-quality iron core materials and minimize the loss caused by the air gaps formed at the seams.

● Miniaturization: The space utilization coefficient is high. The transformer adopts a triangular structure, so the volume is smaller than conventional transformers. It has a compact structure, beautiful appearance, and a small footprint.

● Low noise: Since the three-dimensional triangular rolled iron core is made of several trapezoidal material strips wound in sequence, the silicon steel strips are tightly wound, and the magnetic permeability direction of the silicon steel strip is completely consistent with the magnetic circuit direction of the iron core, so it vibrates during operation. Small, it can solve the noise caused by the incoherent magnetic circuit of the stacked iron core and reduce the noise to the minimum.
