Product Overview
As a kind of clean energy, solar energy is a renewable energy with mature technology and large-scale development conditions. The photovoltaic power generation system uses the photovoltaic conversion of low-voltage direct current of solar cells through the DC lightning protection combiner cabinet and distribution cabinet to enter the photovoltaic grid connected inverter for directAC conversion into low-voltage alternating current, and then into the step-up transformer to make the voltage rise to the rated voltage level grid voltage and complete the grid connection work. The transformer is incorporated into 10kV power grid with low loss, low noise, anti pollution and strong short-circuit resistance. It is widely used in distributed photovoltaic power plants and other fields.
These transformers output two voltages at low voltage, which can be operated simultaneously or separately. The total capacity of each split winding is the rated capacity of the split transformer. The outgoing lines of the two low-voltage windings are copper bars, and at the upper two sides of the coil, compared with the conventional axial up-down outgoing line mode, it greatly facilitates the user's wiring operation.
Product Features
Low loss: the product no-load loss is more than 20% lower than that of SCB11 type products, with excellent energy-saving effect, economical operation and maintenance-free.
Low noise: the noise level of the product is more than 10-15 dB lower than the current professional standard JB/T10088-2004"6-220KV transformer sound level".
Low partial discharge: the resin mixture adopts the most advanced mixing method and vacuum film degassing technology, which makes the mixture mix uniformly and completely excludes the air bubbles in the mixture. The product only has very low partial dis- charge. High and low voltage coils are cast under vacuum and pressure, so that the resin insulation has both full encapsulation and layer turn-to-turn impregnation. The casting body has a dense cured structure, flame retardant, explosion-proof, and does not pol- lute the environment.
The glass fiber and other insulating materials for winding coils have self-extinguishing characteristics, which will not produce arcs due to short circuits, and the resin will not produce toxic and harmful gases under high heat.
High mechanical strength: the resin with filler makes the coefficient of expansion difference within the casting body is small, the cur- ing shrinkage rate is small, the internal stress is small, the hardness of the cured material is high, in the internal and external surfaces of the epoxy resin encapsulation layer of the high-voltage and low-pressure coils, there is a prefabricated reinforcing material placed in the layer, which has the same dense structure as the reinforced concrete, and thus the mechanical strength is greater than that of the pure epoxy resin, and it can withstand the action of sudden short-circuit electric force without any damage.
