Method for protecting conductive lead-out bar in insulated paint immersing process

Abstract

The invention discloses a protection method, which aims to provide a method for protecting a conductive lead-out bar in an insulated paint immersing process. The method has the advantages of high efficiency and capability of protecting the conductive lead-out bar from not being attached to the insulated paint and easily cleaning the painted part. The method comprises the following steps of: uniformly coating a heat conducting silicone grease layer to the conductive lead-out bar; wrapping an adhesive tape on the surface of the conductive lead-out bar coated with the heat conducting silicone grease; immersing a reactor or a transformer product with the conductive lead-out bar processed by the above steps in the insulated paint; carrying out paint baking treatment on the reactor or transformer product; and dismounting the adhesive tape from the conductive lead-out bar and removing all the heat conducting silicon grease. The method disclosed by the invention can be widely applied to the fields of high voltage power transformation.

Description

technical field [0001] The invention relates to a method for protecting conductive lead-out leaching insulating varnish. Background technique [0002] It is necessary to use conductive lead-out bars as line lead-out terminals for wind power or solar power grid-connected reactors and reactors around frequency converters or transformer products. Reactor or transformer products need to be impregnated with insulating varnish to strengthen the insulation, moisture-proof, dust-proof, rust-proof, etc. of the whole product, and the conductive lead-out bar is easily attached with insulating varnish during the dipping process, which will affect the conductive effect. Therefore, when the reactor or transformer is dipped in insulating varnish, it is necessary to protect the conductive lead-out bar. The traditional methods for protecting the leads by dipping paint are as follows: the first method is to wrap tape on the conductive leads before dipping; after baking the paint, remove the ...

Problems solved by technology

[0003] The above-mentioned traditional dipping method has the following disadvantages in the processing process: 1. Reactor or transformer products are dipped in paint after vacuuming, and a small amount of insulating paint can easily penetrate into the conductive lead-out bar through the tape, and then baked at high temperature After baking, the insulating paint is attached to the conductive lead-out bar, which is extremely difficult to clean. During the cleaning process, the lead-out bar is easily scratched and the appearance is poor; 2. When the conductive lead-out bar is polished and sandblasted, the product needs to be protected, which wastes man-hours. And it is easy to cause the reduction of the conductive cross-sectional area. After the power is turned on, the discharge temperature of the conductive lead rises.
