Abstract

The invention relates to a wind power electrical cabinet which comprises a cabinet body. A main power distribution loop for distributing power for devices inside and outside the cabinet body and a grid-tied loop for achieving switching of a power generator and a power grid are arranged in the cabinet body and connected electrically. Multiple devices forming the main power distribution loop are arranged on the left side in the cabinet body, and multiple devices forming the grid-tied loop are arranged on the left side in the cabinet body. The main power distribution loop and the grid-tied loop are arranged on the left side and the right side in the cabinet body respectively, so that power flow in the wind power electrical cabinet is smooth, the whole wind power electrical cabinet is compact, coordinative, attractive, high in space utilization rate and convenient to maintain and meets the domestic and oversea safety requirements during installation, and connecting copper bars are saved.

Description

technical field [0001] The invention relates to the field of energy technology, and more specifically, relates to a wind energy electrical cabinet. Background technique [0002] As a clean and renewable energy, wind energy has attracted more and more attention from all over the world. my country is rich in wind energy resources, and the wind power industry chain is gradually improving. As the core component of the wind turbine system, the converter realizes the variable speed and constant frequency control of the generator to obtain the best power generation efficiency and quality. Among them, the grid connection and power distribution circuit realize the grid connection and off-grid of the converter and the grid, and meet the needs of internal power supply and external power supply. Therefore, the electrical layout and power flow in the converter are particularly important. [0003] The current device layout in the wind energy electrical cabinet is as follows: figure 1 As...
