Product Details

Special box transformer for photovoltaic power generation is a high-voltage/low-voltage pre-installed substation (hereinafter referred to as substation) that integrates high-voltage switchgear, transformer body and protective fuse in the oil tank and integrates with low-voltage switchgear and corresponding auxiliary equipment. It is a kind of special distribution facility that can output power upward after the voltage of 0.27kv or 0.315kv from the photovoltaic grid-connected inverter is raised to 10kV or 35kV through the booster transformer, and it is the ideal supporting equipment of the photovoltaic power generation system.

Substation compact structure, small area, external radiator, better heat dissipation effect.

The substation adopts new transformer series technology, reasonable structure, safe and reliable. · transformer oil is used as the insulating medium for 10KV or 35KV side high-voltage components, greatly shortening the safety distance.

The oil tank adopts the fully closed structure, which makes the oil and atmosphere completely isolated, greatly reduces the oxidation process and water vapor intervention, and improves the stability, reliability and safety of the system equipment.

The cabinet is treated with special shot peening technology, which has good anti-corrosion and anti-insolation ability, and can effectively resist the erosion of sand.

The low voltage side USES the domestic new intelligent circuit breaker, the plastic shell air switch, the segmentation ability is high, the protection performance is good.

The transformer oil tank can be equipped with pressure gauge and thermometer with communication interface, and the load switch can be equipped with travel switch to realize remote monitoring, operation and maintenance of the transformer.

The enclosure is designed with full seal, and the protection grade can reach IP54.
