The substation has a compact structure, a small footprint, and an external heat sink for better heat dissipation.
The substation adopts a new series of transformer technology, with reasonable structure, safety and reliability. · Transformer oil acts as an insulating medium for 10KV or 35KV side high-voltage components, greatly reducing the safety distance.
The fuel tank adopts a fully enclosed structure to completely isolate the oil from the atmosphere, greatly reducing the oxidation process and the involvement of water vapor, improving the stability, reliability and safety of the system equipment. At the same time, the use of the chip radiator is convenient for disassembly and maintenance. simple.
The box body is treated by special shot peening process, which has good anti-corrosion and anti-exposure ability and can effectively resist the erosion of sand.
The low-voltage side adopts domestic new intelligent circuit breaker, molded case air switch, high segmentation capability and good protection performance.
The transformer fuel tank can be equipped with a pressure gauge and a thermometer with a communication interface, and the load switch can be equipped with a travel switch to realize remote monitoring, operation and maintenance of the transformer.
The cabinet is fully sealed and has an IP54 rating.
The special box for photovoltaic power generation is a high-voltage/low-voltage prefabricated substation (hereinafter referred to as a substation) which integrates high-voltage switchgear, transformer body and protection fuses in the fuel tank, and is integrated with the low-voltage switchgear and corresponding auxiliary equipment. ). It is a special power distribution facility that converts 0.27kV or 0.315kV voltage from PV grid-connected inverters to 10kV or 35kV through 10V or 35kV lines. It is ideal for photovoltaic power generation systems. Grouped equipment.
