Paint dipping device for windings of power transformer

Abstract

A paint dipping device for windings of a power transformer consists of an upper pressing plate, a lower pressing plate and three pull screws, wherein three groups of round paint spilling holes and square paint spilling holes are formed on the upper pressing plate, as well as the lower pressing plate. The paint dipping device overcomes the shortcoming that a traditional single or single group of winding has to be fixed by a steel plate for paint dipping and vacuum drying, has a reasonable structure, is uniform in winding stress and good in paint dipping effect and can complete paint dipping ofthree windings of one power transformer at one time. By adopting the paint dipping device provided by the invention, a plurality of windings can be subjected to vacuum drying in each tank, so that the electricity-saving and insulating paint utilization effects are remarkable, the operating efficiency is high and the cost is lowered.

Description

technical field [0001] The invention relates to a winding varnish impregnating device for dry type and oil immersed power transformers. Background technique [0002] At present, the impregnation and vacuum drying of the high and low voltage windings of power transformers are generally carried out after fixing a single or single group of windings with steel plates. Its disadvantages are: ①Each transformer winding needs to be processed several times, but due to the uneven pressure on a single or single group of windings, the effect of dipping paint is not good; ②The windings must be vacuum-dried before and after dipping paint. The single or single set of windings in the dryer takes up too much space in the drying tank, resulting in a limited amount of windings processed in each tank, which not only consumes electric energy, but also reduces work efficiency. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned similar technologies, the purpose...
