Abstract

The invention discloses a power transformer dust collector, comprising a retaining plate arranged at the upper end of a transformer and a mesh plate fixed below the retaining plate.The mesh plate is provided with obliquely downward vent holes, a dust removal brush is arranged between the mesh plate and transformer radiating fins, the dust removal brush is electrically connected with a control board through an electric telescopic rod, the control board is connected with a timer, and the control board and the timer are disposed in an electromagnetic shield.The retaining plate prevents dust carried by rain from falling to a transformer housing, the mesh plate retards the dust at the premise of ensuring ventilation, the dust removal brush is controlled by the control board to regularly move to clear dust accumulating on the transformer fins and the mesh plate, the electromagnetic shield prevents the transformer from electromagnetically interfering the control board and the timer, the power transformer dust collector saves labor, is good for normal operation of the transformer and is simple in structure and easy to popularize.

Description

technical field [0001] The invention relates to a dust removal device for a power transformer, which belongs to the technical field of power equipment. Background technique [0002] A power transformer is an electrical device used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. It is one of the main equipment in power plants and substations. The role of the power transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage used at all levels to meet the needs of power consumption. Common power transformers are mostly installed in the open air. Because they are not cleaned for a long time, the surface often accumulates a thick layer of dust, which affects the heat dissipation of the transformer. Manual cleaning is difficult and time-consuming. Dust removal measures. Contents of the in...
