80KVA Dual Power Combined Transformer Substation Compact Structure 0.4KV
80KVA Dual Power Supply Compact Structure Box-Type Container Prefab Substations
Overview
Box-type substation for American wind power generation (hereinafter referred to as box-type substation) The substation is closely connected with high and low voltage equipment. Among them, the three sides of the substation are exposed to the air, with good heat dissipation conditions, and can be separated from the high and low voltage equipment shells, which is convenient Overhaul.
The substation adopts the S11 series oil-immersed transformer with chip oil tank, no oil pillow, fully enclosed, high and low voltage bushing, tap switch, oil level indicator, pressure relief valve, oil drain valve, etc. They are all installed on the end plate of the main body in the hyperbaric chamber, and the position is reasonable, which is convenient for observation and operation.
The high-voltage cabin and the low-voltage cabin are separated by steel plates. The high-voltage cabin, the low-voltage cabin, and the transformer are relatively independent, while maintaining a complete box-transformation unit, with compact structure, small size and light weight. Install power distribution switchgear on the high and low voltage side.
