Abstract

The invention relates to the technical field of transformer iron cores, in particular to a paint impregnating equipment for iron core transformers, comprising a paint impregnating module and a drying module, the paint impregnating module includes a shell and a guide table, and the bottom surface of the shell is The four end corners of the housing are fixedly connected with outriggers, the middle part of the bottom end of the housing is fixedly connected with one end of the liquid outlet pipe, the other end of the liquid outlet pipe is sleeved and fixed with a valve, and a short end of the housing is The middle part of the side wall is fixedly connected with a vacuum conduit. In the present invention, slide rails are fixedly connected to both sides of the bottom surface of the drying box, and an airtight plate is slidably connected between the two slide rails, so that when the ejector rod drives the placement plate to rise and insert the placement plate into the drying box At the same time, the drying box is closed by sliding the airtight plate. On the one hand, the drying box is sealed to increase the drying efficiency; Spread to the insulating varnish in the lower casing, ensuring the reliability of the unused insulating varnish.

Description

technical field

[0001] The invention relates to the technical field of transformer iron cores, in particular to a paint dipping equipment for iron core transformers. Background technique

[0002] The iron core plays the role of converting magnetic energy into electrical energy and changing the voltage and current in the working engineering of the transformer. It is the core component of the transformer. The iron core is usually made of hot-rolled or cold-rolled steel with a high silicon content and an insulating varnish on the surface. Silicon steel sheets are stacked. In the production process, in order to ensure its insulation performance, the iron core needs to be soaked in insulating paint. After the paint is evenly infiltrated into the inner and outer rings of the iron core, the drying process is carried out. Vacuum impregnation is the most commonly used method of impregnation now;

[0003] In the prior art, the dipping and drying processes usually need to be operated ...
