[0002] In the production process of the reactor, considering the insulation, rust prevention, and mechanical properties of the product, vacuum impregnation with varnish (varnish) is required during the process. The coil terminal is a conductive part and cannot be attached with varnish, so it is attached with tape and a release agent is applied within the specified range of the surface to reduce the amount of varnish adhesion and ensure that it is easier to remove the tape in the later process. The requirement of no varnish adhesion on the coil terminal is achieved.
[0003] At present, when applying mold release agent to transformer coil terminals, varnish is generally poured into a container, and then the operator takes the coil, dips the mold release agent with a brush, and applies the mold release agent on the four sides of the two terminal protective tapes respectively. In this way, the coating uniformity is difficult to control and the coating area is not accurate; the coating process takes a long time, and the mold release agent is easy to volatilize, resulting in material waste and air pollution in the working environment. In view of this, this application is specially proposed. Utility Model Content

[0021] By adopting the above technical scheme, the release agent is stored in a closed material storage pot 3, and then the release agent in the material storage pot 3 flows into the new impregnation tank 4 through the guide pipe 7. Then the operator takes the coil assembly, with the terminal facing downward, and directly puts it into the impregnation tank 4, so that the release agent is attached to the terminal protection tape; the release agent is evenly attached, the coating area is accurate, the coating time is short, and the feasibility of the station merger is improved.
