22kV - 3500kVA Dry Type Transformer Cast Resin Fireproof Dry Type Power Distribution

Three-phase isolation transformers are the main components of various power supplies and electrical equipment, and are manufactured using high-quality materials and advanced technology. The transformer completely insulates the electrical between the primary and secondary sides and isolates the circuit. That way, a short circuit on the primary side does not affect the secondary side. The three-phase isolation transformer not only has the function of voltage transformation in the power grid, but also isolates the third harmonic of the power grid to the equipment, and the primary and secondary plus copper foil shielding, effectively protecting the interference of the power grid harmonics on the equipment. It is especially suitable for import and export equipment between 0.1KVA-1600KVA, suitable for various three-phase power supply occasions with AC 50 ~ 60HZ, input and output voltage not exceeding 1600V. Product input and output voltage (three-phase or multi-channel input and output, etc.), connection method, adjusting tap position, winding capacity allocation, secondary winding equipment, outer box (selected according to different use environments), can be based on user Requires careful design and manufacturing.

1.Iron core:

it is made of high-quality grain orientation cold rolled silicon steel sheet, and adopts 45° full-inclined joint structure and five-grade stepping.

2.Pouring coil:

it adopts F grade insulated copper conductor as the conductor, and adopts glass fiber and epoxy resin composite material for insulation.
3.Foil type coil:

it is automatically winded by foil type coil winding machine and adopts argon shield technology to perform internal welding.

Cast-foil Coil: Adopting the entire section of copper foil, together with the F-class turn insulation, low voltage winding is wound by the special low-voltage foil winding machine. The foil coil resolves such understanding problems as large short-circuit stress, uneven ampere turn, poor heat dissipation, existing the winding spiral angle as well as unsteady manual welding quality due to low voltage and large current coil winding products. At the same time, the winding end in our company is treated with resin potting, solidification to make shape, moisture-proof and anti-fouling, the lead copper platoon is automatically welded by argon arc welding.

4. Temperature Control Device: the transformer adopts BWDK series of signal thermometer. The temperature components, are embedded in the upper half of the low-voltage coil, can automatically detect and dynamically display the work humidity of phase coils and also have the functions of over-temperature alarm and trip.
