Abstract
The utility model provides an insulating structure between metallic glass transformer layer, the coil of this transformer layer upon layer the coiling is placed full adhesive tape and is carried out the interlaminar insulation between coiling coil both ends and middle coil layer, places the point adhesive tape between all the other coil layers and carries out the interlaminar insulation. The utility model discloses a structural design, gaseous discharge in the immersion of coil oil and insulating material has been guaranteed in the use of adhesive tape, effectually avoids corona and office to put to guaranteed insulation system's safety, reliable, because the tip and the middle part quality of coil are the position of the card accuse of the least good, tip and middle layer dielectric strength can be strengthened in the use of full adhesive tape, strengthen holistic mechanical strength, have fine anti short circuit ability to whole transformer.
Description
Technical Field
The utility model relates to a transformer correlation technique field specifically is an insulating structure between metallic glass transformer layer.
Background
The performance requirements of the existing amorphous alloy transformer are high, the requirements on a transformer coil are continuously improved, the requirements on the improvement of the amorphous alloy transformer are generally on the performance of an iron core, the interlayer insulation in the coil of the transformer is not changed, common adhesive dispensing paper is adopted, the structure of the amorphous alloy transformer is that the amorphous alloy transformer is wound by the adhesive dispensing paper from the beginning to the end, the coil is not strengthened, and the strength of the amorphous alloy transformer with higher performance on the coil is not enough.
The transformer is impacted by atmospheric overvoltage and operation overvoltage during operation and is acted by operation voltage for a long time, and the interlayer insulating capability of the coil is reduced due to the fact that a certain voltage gradient exists between coil layers and considering that the coil is possibly influenced by some complex factors such as thermal stress, mechanical stress, electromagnetic force, solvent vapor pressure and the like during the working process. The electrical strength of the transformer is therefore of great importance, and it should be ensured as much as possible that no insulation breakdown occurs anywhere during operation of the transformer. This requires that the coil must be sufficiently strong both in design and manufacture. In the operation of the transformer, the load is constantly changing, i.e. the current is fluctuating, and the electromagnetic force applied to the coil wire is proportional to the square of the current in the coil, so that the coil is required to have sufficient mechanical strength and must be able to withstand strong electromagnetic impacts without structural damage.
SUMMERY OF THE UTILITY MODEL
For solving the not enough of prior art, the utility model discloses combine prior art, set out from practical application, provide an amorphous alloy transformer layer insulation structure, can further improve amorphous alloy transformer coil's job stabilization nature and mechanical strength, have fine anti short circuit ability to whole transformer.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
A layer-to-layer insulation structure of an amorphous alloy transformer is characterized in that coils of the transformer are wound layer by layer, full-adhesive paper is placed between two end parts of the wound coils and the middle coil layer for carrying out layer-to-layer insulation, and adhesive dispensing paper is placed between the other coil layers for carrying out layer-to-layer insulation.
Further, oil channels are arranged at the positions of the wound coils 1/4 and 3/4 for heat dissipation.
furthermore, the adhesive dispensing paper is insulating adhesive paper with a dotted resin coating, and the full-size adhesive paper is insulating adhesive paper with a resin coating applied to the whole paper.
The utility model has the advantages that:
This use neotype structural design, the use of point adhesive tape has guaranteed gaseous discharge in the immersion of coil oil and insulating material, and effectual corona and the office of avoiding is put to guaranteed insulation system's safety, reliable, because the tip and the middle part quality of coil are the position of the best card accuse, tip and middle interlayer dielectric strength can be strengthened in the use of full adhesive tape, strengthen holistic mechanical strength, have fine anti short circuit ability to whole transformer.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
As shown in fig. 1, the coil winding diagram of the transformer is shown, in the diagram, the position of the label 1 is the placement position of the full-adhesive-paper, the position of the label 2 is the placement position of the dispensing paper, and the position of the label 3 is the placement position of the oil passage.
The coil is wound layer by layer, a plurality of pieces of adhesive dispensing paper 2 are used for being placed between each layer, the heat dissipation effect of the oil duct 3 is placed at the 1/4 position and the 3/4 position of the winding coil, the multipurpose adhesive dispensing paper 1 which is not used in the market is used at one-tenth of the winding position 2, the adhesive dispensing paper 1 and the adhesive dispensing paper 2 are different in a point shape from the adhesive dispensing paper 2 which is only a resin coating of the adhesive dispensing paper on the grid, the immersion of oil and the discharge of gas in insulating materials are guaranteed, corona and partial discharge are effectively avoided, and therefore the safety and reliability of an insulating structure are guaranteed. The full-size paper 1 is coated with resin because the ends and the middle of the coil are substantially the same mass.
The position of the coil is not easy to be clamped (because the acting force and the reaction force generated by the current in the middle of the coil are the largest when the current passes through the coil, the strip-shaped balloon is easy to blow and explode in the middle, the rope similar to a tug-of-war is also easy to break in the middle, namely the linear object is generally the largest in the clamping plate gas received in the middle, the current passes through the coil, the whole gummed paper 1 is placed in the middle, the middle interlayer insulation strength is enhanced, the integral mechanical strength is enhanced, the gummed paper 2 is used in other layers to ensure the invasion of oil, the heat dissipation effect is achieved, and the voltage applied to the end part at one moment by the end part is far higher than the voltage applied to other layers. Has good short-circuit resistance to the whole transformer.
