Description
Low Noise Dry type Transformer
This series of dry-type transformers adopt a special structure. Under the premise of meeting the various performance parameters of the standard, the overall dimensions are optimized to fully meet the installation requirements of the center cabinet and high-voltage switch cabinet. It is an ideal matching transformer for middle cabinets and high voltage switchgeats at present.
three phase dry type electric transformer
1.Safe, fireproof, no pollution, it can be installed directly in the load center.
2.Free maintenance, easy to install, low total operating costs.
3.With good moisture resistance, it can work normally under the100% humidity. After it stopped operating, the outage without pre-drying can be put into operation again.
4.Low loss, low partial discharge, low noise, good heat dissipation capacity. Under the forced air cooling conditions, it can run at 150% rated load.
5.The equipped perfect humidity protection & control system can provide reliable
Function Characteristics:
1. Flame retardant, non-pollution, it can be installed directly in the load center.
2.Maintenance-free, easy to be installed, low operating costs.
3.The enclosure can be of Good moisture resistance, transformer can be put into operation without pre-drying under 100% humidity in the normal operation.
4.Low loss, light weight and small volume, low noise, good dissipation of heat, it can be 150% rated load operation under forced air cooling conditions.
5.Equipped with a complete temperature protection control system to provide reliable protection for the safe operation of
transformers.
6.High reliability. The results of checking for the products that has been put into operation show that the reliability index has reached the international advanced level.
Structural Characteristics:
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.
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.
