Problems solved by technology
The existing American-style box substation uses an oil-invasion load switch for high voltage electric substation, which is installed in the same airtight box as the transformer, which is inconvenient to maintain; while the European-style box substation installs the transformer in a metal box, although it plays a competitive role, But the heat dissipation effect is poor, and the volume is large, and it is inconvenient to carry

The invention provides a wind power generation boost and inversion column type integrated machine, which comprises a box body. The box body is internally provided with a high-voltage chamber, a transformer chamber and an inversion chamber from top to bottom. Thermal insulation layers and passages are arranged between the high-voltage chamber and the transformer chamber and between the transformerchamber and the inversion chamber. The high-voltage chamber is internally provided with a high-voltage cabinet, and the high-voltage cabinet is internally provided with a vacuum load switch. The transformer chamber is internally provided with a transformer. A fuse is arranged between the vacuum load switch and the transformer. The inversion chamber is internally provided with an inverter cabinet and a manhole. The high-voltage cabinet, the transformer and the inverter cabinet are all connected by cables. The transformer chamber and the inversion chamber are internally provided with ventilationducts. The box body is provided with a fireproof and heat insulating layer. The wind power generation boost and inversion column type integrated machine of the invention has the advantages of compactstructure, convenient installation, highly integrated functions and low cost.
Description
technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a wind power generation step-up inverter column-type integrated machine. Background technique [0002] In the field of wind power generation, the box transformer is a crucial equipment. It organically combines the functions of transformer step-down and low-voltage power distribution, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, and anti-theft. The heat-insulated, fully enclosed, and movable steel structure box replaces the original civil engineering power distribution room and power distribution station, and becomes a new type of complete power transformation and distribution device. The existing American-style box substation uses an oil-invasion load switch for high voltage electric substation, which is installed in the same airtight box as the transformer, which is inconvenient to maintain; while the European-...
