Resin-insulated dry-type transformer with three-dimensional coil core is the perfect combination of three-dimensional coil core and resin-insulated dry-type transformer. This product not only has the advantages of saving energy and material, no-load loss and low no-load current, but also has the characteristics of good electrical performance, low partial discharge value, strong lightning impulse resistance, strong short-circuit resistance and high mechanical strength of resin insulated dry-type transformer. This product is produced.
The application and promotion of dual energy-saving products conform to the national energy-saving and emission reduction policies.
The products are suitable for high-rise residential buildings, airports, stations, wharfs, metros, hospitals, power plants, metallurgical industries, shopping centers, densely populated areas, Petrochemical nuclear power plants, nuclear submarines and other places.
1. Frame clamps
The upper and lower clamps are integral, which protects the whole iron core from external force during manufacture and transportation. They can effectively compact and support the coil, and improve the resistance to axial electric force of transformer in sudden short circuit.
Power.
2. Seismic noise reduction
Section steel structure and clamp can effectively oscillate the noise in the clamp, so that the noise of transformer can be kept in an ideal state.
3. Good electrical performance and low partial discharge value
Epoxy resin and curing agent use high-grade insulating material, high-voltage colour and thin insulating material pouring structure, pouring mixture can be completely immersed into each gap of the coil, to eliminate the existence of the gap.
In addition, it can effectively resist the occurrence of partial discharge.
4. Strong Short Circuit Resistance
Because of the material characteristics of the resin and the integral casting of the winding, it has excellent mechanical properties after heating and curing, so the mechanical strength is very high. Short circuit test proves that resin casting.
Injection dry transformer is rarely damaged due to short circuit.
5. High mechanical strength
The transformer is solidified by epoxy resin with filler and special insulation structure, and the material is stable. It will not crack due to bad weather and temperature variation.
6. Moisture-proof and fire-resistant
Because the whole coil conductor is encapsulated by epoxy resin solid insulating layer, it is difficult for moisture to invade, and the insulation grade of interlayer insulating film reaches F grade.
