Abstract
The invention discloses an insulating paint for an enameled wire and an application method of the insulating paint. The insulating paint disclosed by the invention is 225 polyesterimide insulating paint and 1766 polyesterimide insulating paint of which the temperatures are both 200 DEG C. By virtue of the insulating paint, the relatively high adhesive strength as well as relatively high temperature resistant index of the product are ensured. By mixing the insulating paint with a matched solvent, a suitable viscosity is reached; after the enameled wire is coated with the insulating paint, the experiment shows that the enameled wire has good adherence; after the enameled wire is elongated by 20% (with respect to the national standard, by 15%), the thickness of the insulating layer losing the adherence is not more than 1b. The breakdown voltage of the enameled wire is stable and can be stabilized at 4000-5500V.
Description
Technical field
The present invention relates to Production of Enamel Wires technical field, particularly relate to a kind of insullac and using method thereof of enameled wire.
Background technology
The principle of steam turbine generation current is that rotor rotates generation magnetic field, stator bar cutting magnetic line, generation current.Generating set internal stator line rod part belongs to the key part of motor, and the stator bar of the outer big-and-middle-sized steam turbine of Current Domestic adopts enamel-cover sintering line to make mostly.Whether the enamel-cover sintering line insulation layer electric property that a topmost performance is exactly product in the course of receiving can meet the demands.This product, due to motor self design requirement, mainly need to rely on the paint film of 10 left and right of enameled wire to carry out insulation protection.Because the voltage performance of enameled wire is unstable, often cause stator coil to occur punch-through.By the insullac using in configuration Production of Enamel Wires, can effectively solve the voltage performance of enameled wire.
In process of production, japanning process is most important for enameled wire, and the service condition of insullac directly affects the performance of enameled wire.Present stage, the insullac that domestic each manufacturer is used is directly bought from producer mostly, without directly use of modulation, in use often occurs that enamelled wire surface insulation layer tack is unstable, voltage breakdown is on the low side and unstable.So in order to improve tack and the voltage performance of enameled wire, domestic each producer brings into use the former paint of insullac by adding other composition configuration insullac, but because grasping bad allocation ratio, the tack of enameled wire and voltage performance still cannot improve.
