Product Characteristics:
1. safe, fire-retardant, fireproof and pollution-free.
2. It can be directly installed at the load center, is free of maintenance and easy and convenient to install, and has low comprehensive running cost.
3. With high moisture resistance, it runs normally at the moisture of 100% and can be put into operation without being dried after outage, with low loss and local discharge capacity.
4. It has small noise, strong short circuit resistance and excellent environmental performance, and can run under severe environmental condition.
Product Structure:
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.
Applications
This kind SC(B)&SG(B) dry type power transformer is applied to power system of three-phase, 50Hz as well as 35kV and below, it is the main transformer equipment of medium and small-sized transformer substation, supplies power distribution, power and illumination for the industry and agriculture, Hotel airport, power plant, hospital, skyscraper, shopping center and residential areas.
