This series of epoxy numerically poured dry transformer material is of high quality and scientific formulation. It is produced by adopting advanced production and testing equipment according to strict process. The product features high reliability and long service life. Shell with or without different protection levels can be configured depending on the use environment.
Functional Features:
Safe, fireproof, no pollution, can run directly in the load center.
Using German HTT technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability, service life plant.
Low loss, low noise, obvious energy saving, no maintenance.
Good heat dissipation performance, strong overload capacity, forced air cooling can improve the capacity of operation.
Good moisture resistance, suitable for high humidity and other harsh environment.
Can be equipped with perfect temperature monitoring and protection system. The intelligent signal temperature control system can automatically monitor and display the working temperature of three-phase windings. The fan can be started and stopped automatically.
And there are alarm, trip and other functions set.
Small size, light weight, less space, low installation cost.
The iron core is made of high quality cold-rolled silicon steel, with 45-degree step full oblique joint structure. The technology of three-shear and two-punch iron core to remove Angle cross shear and the technology of five-step cutting and folding iron are used to improve the magnetic flux distribution at the joints and reduce the vibration energy of the iron core. The core is cured in one piece and sealed with insulating resin on the surface, which can effectively reduce the no-load loss, no-load flow and core noise.
The high voltage coil is made of high quality F-class insulated wire and international advanced insulating material, and the large capacity coil is provided with heat dissipation airway along the axis. The structure has good resistance to current shock, temperature change, cracking and heat dissipation. The multi-stage segmented cylinder structure has a strong ability to withstand overvoltage and a very low partial discharge level. The coil mold is poured after vacuum drying,
The whole casting and curing process is completed according to the preprogrammed process curve, and the precise process control ensures that the coil has no pores and holes.
Low voltage coils, adopting the foil structure can effectively solve the low voltage, high current coil using wire wound type of ampere-turns imbalance, foil coil at the same time there is no axial axial spiral Angle, number of turns and effectively eliminate the short circuit of transformer axial force, ensures that the current density inside the coil can freely according to the high voltage coil load distribution along the axial adjustment, reduced low-pressure sudden short circuit when the radial force. The end of the wound coil is sealed and cured with resin to avoid the entry of various foreign bodies and moisture.
