Abstract
The invention relates to the technical field of insulating laminating pieces, and specifically relates to a method for manufacturing an insulating laminating piece of a transformer. The method comprises the following steps of: (1) pre-heating treatment, namely applying the pressure of 10-20 kg/cm<2> to a workpiece, and gradually warming the workpiece, wherein after 3-5 min, the temperature of the workpiece reaches 80-100 DEG.C, and the pre-heating time is 8-12 min; and (2) insulation treatment, namely gradually warming the workpiece in the step (1) to 120-140 DEG.C under the original pressure, wherein the heat preservation time is 2min/mm, and the heat preservation time is not shorter than 30 min when the thickness of the workpiece is less than 15mm. The insulating workpiece is treated by pre-heating, heat preservation, pressure maintaining and other steps, and the temperature, pressure and time are effectively guaranteed in the treatment process so as to improve the insulating grade; the insulating effect is good, the operation performance of the transformer is stable, the normal use of the transformer is guaranteed, and the service life of the transformer is effectively prolonged.
Description
Technical field
The present invention relates to the insulating laminated part technical field, be specifically related to the insulating laminated part manufacture method of transformer.
Background technology
At present, the insulating laminated part of existing transformer is because manufacture method or step are reasonable not, thereby so that the class of insulation reduces, insulation effect descends, so that the runnability of transformer is unstable, has affected the normal use of transformer, shortens its useful life.In addition, the manufacture method of existing transformer insulated laminate or process are complicated, complex operation.
Summary of the invention
The purpose of this invention is to provide a kind of technique simple, easy to operate, be easy to control and grasp its temperature, pressure and time, raising insulation effect, guarantee the insulating laminated part manufacture method of the transformer that the product runnability is stablized, increased the service life.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: the insulating laminated part manufacture method of transformer may further comprise the steps:
(1), the pre-heat treatment: at first workpiece is imposed 10～20Kg/cm
2Pressure, heat up gradually again, behind 3～5min, make workpiece temperature reach 80～100 ℃, be 8～12min warm-up time;
(2), insulation processes: the workpiece in the described step () is raised to temperature gradually under original pressure be 120～140 ℃, and temperature retention time is 2min/mm, and when thickness of workpiece during less than 15mm, temperature retention time just is no less than 30min;
(3), pressurize is processed: after the workpiece in the described step (two) enters into 1/4 time of holding stage, exert pressure according to the thickness of workpiece, generally speaking, give workpiece and apply 40～60Kg/cm
2Constant pressure; Higher for requirement of mechanical strength, applied pressure is 80～100Kg/cm
2Constant pressure.
The present invention has following beneficial effect: the insulating laminated part manufacture method of transformer of the present invention, adopt the steps such as preheating, insulation and pressurize that the insulation workpiece is processed, and the temperature in its processing procedure, pressure and time are all effectively guaranteed, thereby so that the class of insulation improves, insulation effect is good, the runnability of transformer is stable, has guaranteed the normal use of transformer, and has effectively prolonged useful life.In addition, the present invention has that technique is simple, easy to operate, temperature, pressure and time is easy to grasp and control.
Embodiment
Below the present invention will be further described in detail.
Embodiment one:

2Pressure, heat up gradually again, through behind the 3min, make workpiece temperature reach 80 ℃, be 8min warm-up time; Need to prove, in this step, need first cleaning surfaces, the intact even brushing gluing of insulating board, behind the natural air drying 4 hours, be convenient to hot pressing for subsequent use, wherein the effect of preheating is that resin can be dipped in the cavity of cardboard itself fully, and the moisture of cardboard and air can be vapored away, to increase the bonding strength of workpiece.
(2), insulation processes: the workpiece in the described step () is raised to temperature gradually under original pressure be 120 ℃, and temperature retention time is 2min/mm, and when thickness of workpiece during less than 15mm, temperature retention time just is no less than 30min; In this step, the effect of insulation is that resin carries out the course of reaction that cross linkage solidifies, and its temperature is effectively guaranteed.
(3), pressurize is processed: after the workpiece in the described step (two) enters into 1/4 time of holding stage, exert pressure according to the thickness of workpiece, generally speaking, give workpiece and apply 40Kg/cm
2Constant pressure; Higher for requirement of mechanical strength, applied pressure is 80Kg/cm
2Constant pressure; In this step, the effect of pressurize is the stage that reduces for resin solvent, moisture evaporation, cal(l)iper, and its pressure is effectively guaranteed.
