Description

Technical Field

[0001] The utility model relates to the technical field of wind farm capacitors, in particular to an installation structure of a wind farm capacitor. Background Art

[0002] As a reactive power compensation device, power capacitors can solve the reactive power, voltage fluctuation and flicker problems of wind power generation systems, and ensure the normal operation of various electrical equipment in wind power generation systems. In order to assist the stable installation of wind farm capacitors, an installation structure for wind farm capacitors is required.

[0003] During use, the traditional installation structure of wind farm capacitors mostly uses bolts to assist the bottom of the wind farm capacitor to be installed on a tray or beam inside the wind converter between the wind turbine generator set and the power grid, and then the tray or beam is fixed to the inside of the wind converter by welding or bolt positioning. However, the traditional installation method causes the bolts to be easily affected by the external environment after the capacitors are installed for a long time, resulting in idling of the bolt bodies during disassembly, making it difficult to assist the capacitor to be quickly disassembled, and the capacitor body is easily affected by the surrounding environment during the installation process. When the wind power converter shakes, the capacitor body is easy to move with the wind power converter, which can easily cause damage to the capacitor body, thereby affecting the stable use of the capacitor body.
