Cast Resin Dry Type Transformers Cast Coil Power Electrical Transformers For Nuclear Plants
The series of epoxy cast dry-type transformers value high-quality materials, formulation science,
advanced manufacturing and testing equipment is made according to strict production process. Products with high reliability and long life characteristics. Depending on the use of the environment, can be configured to different levels of protection or do not configure the shell casing. For high-rise buildings, commercial centers, airports, tunnels, chemical plants, nuclear power plants, ships and other important places or special environment.
1. Security, fire, pollution-free, can be run directly on the load center.
2. HTT using German technology, high mechanical strength, resistance to short-circuit capability, partial discharge, thermal stability, high reliability and life of plants.
3. Low loss, low noise, energy-saving effect, maintenance-free.
4. Thermal performance, overload capability, forced air cooling can increase the capacity to run.
5. Moisture resistant, and adapt to high humidity and other harsh environments.
6. Can be equipped with temperature monitoring and improve the protection system.
7. Temperature control system using intelligent signal, automatically monitor and display three-phase winding road of their operating temperature, can automatically start and stop the fan, and has an alarm, trip and other functions set.
7. Small size, light weight, small footprint, low cost of installation.
8. High quality cold-rolled silicon steel core, 45-degree miter joints ladder structure, the use of three core cut to the corner two red and five cross-cutting process step ladder and stacked cut sheet iron craft, improved the seams of the flux distribution, reducing the core of the vibrational energy.
9. One core to the surface with insulating resin curing and sealing process, effectively reducing the load loss, load flow and core noise.
10. High voltage coil insulation class F high-quality wire and advanced insulation materials around the system, with a larger capacity cooling coil along the axial airway.
11. This structure has good resistance to current impact, temperature resistant, anti-cracking and excellent heat dissipation.
12. Multi-level sub-cylindrical structure, strong ability to withstand over-voltage and low partial discharge level.
13. Coil fitted after the casting mold by vacuum drying, the whole process of casting and curing process in accordance with pre-programmed to complete the curve, precise process control to ensure that the coil no holes, holes.
14. Foil using low-voltage coil structure, effectively low-voltage, high current coil ampere-turns using wire-wound type of imbalance, but there is no axial foil coil winding turns and axial spiral angle, effectively eliminating transformer short-circuit axial force to ensure that the coil current density within the high voltage ring load can be distributed freely along the axial adjustment to reduce the sudden short-circuit when the low radial force.
15. After winding the coil end of the curing resin seal, to avoid the entry of foreign matter and moisture.
1. The maximum ambient air temperature shall not exceed 40 ℃, and the minimum shall be not below - 15 ℃;
2. The altitude shall not exceed 1000m. If special customized transformers and low-voltage components are used, the altitude can reach 4000m;
3. The vertical inclination is no more than 5 °, and no violent vibration and impact;
4. The air humidity is not more than 90% (+ 25 ℃);
5. Places without gas and conductive dust that will seriously affect the insulation of transformer, no explosion hazard and corrosion of electrical components;
6. Outdoor wind speed shall not exceed 35m / s.
7. If service conditions exceed the above, specially customized product is available with our company through mutual communication.
