A paint brushing device for heat sinks of transformers

Abstract

The invention discloses a transformer cooling fin paint brushing device which comprises a paint brushing box; a paint brushing space is arranged in the paint brushing box; a motor case is in sliding fit with the interior of the paint brushing space; a motor cavity is formed in the left side of the interior of the motor case; a motor is in sliding fit with the interior of the motor cavity; a sliding cavity is formed in the left and right walls of the motor case in a penetrating manner; and the motor is in power connection with a motor shaft in sliding fit with the sliding cavity, so that paintbrushing operation on a transformer cooling fin can be excellently finished; and a paint brushing barrel can be always filled with paint and rotates stably and moves up and down, and the paint brushing thickness can be uniform, so that the overall operation is very simple, the manual operating steps are fewer, the labor intensity is low, and the paint brushing failure probability caused by a humanerror can be reduced.

Description

technical field [0001] The invention relates to the technical field related to substations, in particular to a paint brushing device for heat sinks of transformers. Background technique [0002] The transformer heat sink is a part welded on the outer wall of the transformer oil tank. It is used to dissipate the heat caused by the hysteresis loss of the transformer core, the eddy current loss and the copper loss of the coil faster. Since the transformer is generally placed in the open air, Therefore, the exterior of the transformer needs to be painted for protection, and the heat sink is the same. Since the heat sink is arranged evenly and tightly, it is difficult to paint the inside of the heat sink well, so the thickness is thin or even not sprayed with paint. The area is relatively easy to be corroded, so the conventional painting method may not be or not suitable for the transformer heat sink, and for the spray paint, there may be uneven thickness or flow marks on the upp...

The area is relatively easy to be corroded, so the conventional painting method may not be or not suitable for the transformer heat sink, and for the spray paint, there may be uneven thickness or flow marks on the upper and lower parts, and there may be a certain amount of labor intensity and Human factors lead to the possibility of painting failure
