Description

Cage type filter screen of cooling fan

Technical Field

The utility model belongs to the technical field of wind power generation, in particular to cooling fan cage filter screen.

Background

Most wind power stations in China are built in remote coastal areas, and the environment around the wind power stations is severe. In windy weather, a great deal of dust floats in the air. In summer each year, coastal areas are affected by subtropical monsoon climate and sea-land terrain, the prevailing southeast wind, floccules (poplar wadding, willow wadding and the like) floating in the air float to the sea along with the prevailing monsoon, and the floccules enter a heat dissipation air inlet channel and then are stacked to block a heat dissipation grid of a cooling heat dissipation system, so that the normal operation of a unit is affected.

A converter and transformer cooling and heat dissipation system is one of key auxiliary systems of a wind generating set and is an important guarantee for ensuring the safe and stable operation of the set. When floccules are accumulated to block a cooling grid of a cooling and radiating system, the cooling and radiating system is not smoothly ventilated, so that cooling water cannot be cooled in time, the temperature of the transformer is finally too high or the converter is over-heated, and finally a fan is forced to reduce power and operate or even shut down, thereby causing huge power generation loss.

The traditional method for solving the problems mainly adopts a manual cleaning mode and adds a filtering device at the position of a heat dissipation grid plate of a generator set. However, the existing filtering device can not isolate the floccules, and when a large grid is blocked and a large amount of floccules are attached to the surface of a cooling grid of a cooling system, the manual cleaning speed can not obviously follow the blocking process, so that the problem can not be solved fundamentally.
