Product Introduction
▶ Products
Photovoltaic, wind power generation as a clean and non-polluting energy, has been widely promoted and applied. 35kV photovoltaic / wind power generation special combined transformer (referred to as 35kV new energy American box variable), is a high-voltage electrical components, step-up transformer and low-voltage switchgear, measurement and control protection devices, according to the electrical wiring scheme diagrams, the combination of an outdoor factory prefabricated power equipment. Including: oil-immersed step-up transformer, high-voltage load switch, high-voltage fuse, high-voltage arrester, low-voltage circuit breaker, measurement and control devices and power transformer and other auxiliary equipment, respectively, installed in the transformer tank, high-voltage gas room and low-voltage electrical room. The low-voltage outgoing line of the PV transformer can adopt double-split structure according to the user's needs.
▶▶ Applicable standards
GB 17467 High-voltage/low-voltage pre-assembled substations
GB/T6451 "Oil-immersed Power Transformer Technical Parameters and Requirements".
GB 1094 Power Transformer
JB/T 10217 Combined Transformers
GB/T15166 《 High Voltage AC Fuses》.
GB7251 《 Low-voltage complete sets of switchgear and control equipment》.
GB4208 "IP Protection Level".
▶▶ Structural characteristics
The U.S. box variable for photovoltaic/wind power generation adopts oil-immersed high-voltage load switches and high-voltage fuses, i.e., the high-voltage load switches and high-voltage fuses are immersed in the transformer oil tank. Therefore, it has small volume, small footprint, transformer tank is exposed in the external environment, so the heat dissipation effect is good, the overload capacity is strong, the overall sealing, high protection level. Box has enough mechanical strength, in transportation, installation will not be deformed. Appearance and color coordination with the environment. The shell paint spraying is uniform, anti-explosion sunshine, corrosion resistance, wind and sand resistance, with solid adhesion, the product's protection grade can reach IP54 requirements.
