Description

SVG water-cooled radiator automatic cleaning device and cleaning method

technical field

The invention belongs to the technical field of cleaning SVG water-cooled radiators, in particular to an automatic cleaning device and a cleaning method for SVG water-cooled radiators.

Background technique

my country vigorously develops new energy sources such as wind power and photovoltaics; due to the inherent instability of energy sources, wind power and photovoltaics lead to poor stability of power output, and reactive power compensation devices must be equipped. Static var generator (SVG) is widely used in wind farms, photovoltaic power stations and other places. The static var generator is installed between the load and the grid to ensure the stability of the power supply in the grid during the process of supplying power to the load.

The current mainstream reactive power compensation device is basically the third-generation reactive power compensation device SVG. In recent years, with the widespread use of SVG, some disadvantages of SVG have gradually emerged. Among them, heat dissipation is the most important factor affecting the stable operation of SVG. The heat dissipation of water-cooled SVG is better than that of air-cooled SVG. The water-cooled SVG includes a water-cooling radiator. The water-cooling radiator is provided with a cooling fan for cooling the circulating water. Filter elements are provided at the upper and lower ends of the cooling fan. The filter elements include a filter screen and a filter grille.

At present, the existing filter elements of water-cooled radiators are all fixedly installed, and lack automatic cleaning devices; or some cleaning devices (such as a filter cleaning device for air purifiers disclosed in CN202110953853. For scraping, since the water-cooled radiator is always in working condition, if you scrape directly on the filter of the water-cooled radiator, a lot of dust will penetrate the filter and reach the inside of the device under the combined action of the brush body and negative pressure, thereby reducing the filter capacity.
