Abstract
The utility model discloses a piece of aluminum foil shield insulating paper, which relates to insulating paper and is formed by aluminum foil layers (1) and a paper base (2). The aluminum foil layers (1) are adhered onto the paper base (2) with consistent spacing, smoothness and tightness. The paper base has firm adhesion and stable size without shortages of corrugation, bubble and the like, and the insulating paper has size and specification more suitable for design requirements of domestic transformer products. In use of a transformer, the insulating paper is difficult to generate problems such as poor mechanical strength, misplacement of products, partial discharge, polluting transformer oil and the like, and improves insulation performance and safety and reliability of the transformer.
Description
Technical field:
The utility model relates to a kind of insulating paper, especially a kind of aluminum foil shielded insulating paper.
Background technology:
The principle of aluminum foil shielded insulating paper research foundation be by the metallic shield body by electromagnetic reflection with absorb the far zone field of radiation-screening interference source, the electric field and the magnetic-field component that shield field source simultaneously and produced.
The aluminum foil shielded insulating paper is mainly used in ground screen, electrostatic screen layer and the winding conductive layer of transformer, instrument transformer and reactor, distributes to improve electromagnetic field, reduces partial discharge, reinforced insulation.
In the process that manufacturers such as the research institution of relevant transformer and many transformers, instrument transformer, reactor are investigated, the designer of many High-Voltage Electrical Appliances proposes, in high-tension electricity devices such as transformer, use the shielding insulation material for improving Electric Field Distribution, reinforced insulation intensity, the security and stability that improves High-Voltage Electrical Appliances has very significant effect.Developed countries has generally used the shielding insulation material.The domestic product that only has small part producer to adopt offshore company to produce, but its price is expensive.And many transformer factories adopt conventional adhesive, common cable paper, make shielding paper with artificial sticky method, and the product of making exists that the paper substrate bonding is not firm, size is unstable, wrinkling and many defectives such as bubble are arranged.In the use of transformer, cause easily that mechanical strength is bad, product dislocation, partial discharge, pollution transformer wet goods problem, have a strong impact on the insulation property and the security reliability of transformer.
The utility model content:
The purpose of this utility model provides a kind of aluminum foil shielded insulating paper, its paper substrate bonding firmly, dimensionally stable, do not exist wrinkling and defective such as bubble arranged, size, specification are more suitable for the designing requirement of domestic power transformer product.In the use of transformer, be difficult for causing that mechanical strength is bad, product dislocation, partial discharge, pollution transformer wet goods problem, improve the insulation property and the security reliability of transformer.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of aluminium foil layer 1 and paper substrate 2, and aluminium foil layer 1 is consistent at interval, smooth sticking in closely on the paper substrate 2.
Its technological process of production: cable paper uncoiling, adhesive synthesize → gluing → oven dry (simultaneously, aluminium foil is cut → the aluminium foil uncoiling) → compound → isolation → rolling → aluminum foil shielded insulating paper → check → rolling → isolation.
The utility model adopts omnidistance computer-controlled combination process system to produce, and by many frequency converters compound, gluing, rolling, traction electric machine is carried out Synchronization Control, detects by tension force to feed back to controller tension force is carried out PID control.Simultaneously, use formula controller PLC able to programme to carry out centralized control, and adopt man-machine interface that complete machine is operated, and make parameters such as running speed, compound tension force, gluing moment, rolling tension force, drying tunnel temperature keep synchronous coordination, guarantee aluminium foil consistent with the interval between the aluminium foil (3mm).The employing non-polar material is isolated, and prevents adhesive and the adhesion of the finished product back side effectively, thereby guarantees to produce smooth, smooth, as not have wrinkle excellent product.
Paper substrate of the present utility model bonding firmly, dimensionally stable, do not exist wrinkling and defective such as bubble arranged, size, specification are more suitable for the designing requirement of domestic power transformer product.In the use of transformer, be difficult for causing that mechanical strength is bad, product dislocation, partial discharge, pollution transformer wet goods problem, improve the insulation property and the security reliability of transformer.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is technological process of production figure of the present utility model.
Embodiment:
With reference to Fig. 1-2, this embodiment by the following technical solutions: it is made up of aluminium foil layer 1 and paper substrate 2, and aluminium foil layer 1 is consistent at interval, smooth sticking in closely on the paper substrate 2.

It is 1.08g/cm that described paper substrate 2 is selected density
3, the water extract conductivity is 2.2Ms/m, and pH value is 7.3, and hot strength is 140N/mm
2The high density insulating paper.
Its technological process of production: cable paper uncoiling, adhesive synthesize → gluing → oven dry (simultaneously, aluminium foil is cut → the aluminium foil uncoiling) → compound → isolation → rolling → aluminum foil shielded insulating paper → check → rolling → isolation.
This embodiment adopts omnidistance computer-controlled combination process system to produce, and by many frequency converters compound, gluing, rolling, traction electric machine is carried out Synchronization Control, detects by tension force to feed back to controller tension force is carried out PID control.Simultaneously, use formula controller PLC able to programme to carry out centralized control, and adopt man-machine interface that complete machine is operated, and make parameters such as running speed, compound tension force, gluing moment, rolling tension force, drying tunnel temperature keep synchronous coordination, guarantee aluminium foil consistent with the interval between the aluminium foil (3mm).The employing non-polar material is isolated, and prevents adhesive and the adhesion of the finished product back side effectively, thereby guarantees to produce smooth, smooth, as not have wrinkle excellent product.
The paper substrate of this embodiment bonding firmly, dimensionally stable, do not exist wrinkling and defective such as bubble arranged, size, specification are more suitable for the designing requirement of domestic power transformer product.In the use of transformer, be difficult for causing that mechanical strength is bad, product dislocation, partial discharge, pollution transformer wet goods problem, improve the insulation property and the security reliability of transformer.
