Product Description

Transmission and distribution system from distant power plants will be delivered to the user by adjusting the electrical energy transmitted through high voltage transmission lines, and substations buck after a few levels to suit the user. Located near the end-users of electricity distribution transformers reduce the voltage to a suitable final value. The voltage is reduced to electrical equipment operating voltage transformer called distribution transformers, transformers such as power plants with a daily lighting and generally low-to 0.4kV and below. Distribution transformer capacity is small, generally in 2500 kVA and below; Once the voltage is lower, in 35 kV and below. Unlike ordinary oil-immersed transformers, I produced a sealed distribution transformer conservator removed from the main body of the fin corrugated tank as the heat expansion and contraction components, transformer oil and the atmosphere is completely isolated. Including the transfer capacity of distribution transformers and dual voltage transformers and distribution transformers. Yung tune with the size of the transformer is a two-capacity, and can be adjusted according to load size distribution transformers. Changing the high voltage winding connection methods, and low-voltage winding series of conversion as well as the adjustment of the tap without excitation by a special tone volume switch is complete. Meanwhile, large-capacity transfer small capacity, low pressure due to the increased number of turns, the core flux density significantly reduced, leaving the smaller loss silicon steel unit, load loss and no-load current is also reduced, to Energy Conservation purposes. Dual voltage distribution transformer is a kind of size of the two voltages, and can be adjusted according to the grid voltage distribution transformers. High voltage winding and the series of transformations, and then adjust each sub-section of the non-excited by a special switch is complete.
