Abstract
The utility model relates to an insulating pressing block for a transformer, which comprises a pressing block body and is characterized in that an elliptical fixing hole is formed on the upper end surface of the pressing block body; a convex gripping head is arranged on the lower end surface of the pressing block body; a clamping groove used for fixing an insulating plate is formed at the middle part of the convex gripping head; and a high-voltage lug boss used for fixing a high-voltage coil and a low voltage lug boss used for fixing a low-voltage coil are respectively arranged on two sides of the convex gripping head. The insulating pressing block is applied to the transformer, can define the positions of the high-voltage coil and the low-voltage coil conveniently, leads the high-voltage coil and the low-voltage coil to be separated, improves the insulating property of the high-voltage coil and the low-voltage coil, enables the high-voltage coil and the low-voltage coil to be installed stably, achieves good insulating effect, ensures the safe operation of the transformer, and is worth popularization and application.
Description
Technical field
The utility model relates to a kind of briquetting, what be specifically related to is a kind of insulation pressing that is used for fixing coil in the transformer that is applied in.
Background technology
As everyone knows, transformer station is some device assembles, and in order to cut off or to connect, to change or to adjust voltage, in electric power system, transformer station is the assembly place of transmission and disttrbution.Transformer is the capital equipment of transformer station, and transformer (especially high-tension transformer) is particularly important to the installation of height coil, and it installs instability can cause the short circuit of circuit and the increase of transformer noise, influences transformer's life span.The height coil of high-tension transformer is nested installation in the prior art, there is many deficiencies, and like the coil pretension, insulation between it and stability are difficult to grasp, and make high-tension transformer exist hidden danger, influence transformer's life span.
The utility model content
To the deficiency that exists on the prior art, the utility model purpose be to provide a kind of can be conveniently fixedly high-tension coil and low-voltage coil position, make its stable installation, transformer that insulation effect is good use insulation pressing, guarantee the high-tension transformer security of operation.
To achieve these goals, the utility model is to realize through following technical scheme:
Transformer is used insulation pressing; Comprise the briquetting body; It is characterized in that said briquetting body upper surface is provided with oval-shaped fixing hole, its lower surface is provided with protruding chuck; Be provided with the draw-in groove that is used for fixing insulation board in the centre of said protruding chuck, be respectively equipped with high pressure boss that is used for fixing high-tension coil and the low pressure boss that is used for fixing low-voltage coil in protruding chuck both sides.
Transformer according to above-mentioned is used insulation pressing, and wherein, said briquetting body material is the insulating epoxy material.
The utility model is applied in the transformer through technique scheme, can be conveniently fixedly high-tension coil and low-voltage coil position; Its low-voltage coil is separated with high-tension coil; Increased high-tension coil and low-voltage coil insulation property, and made its stable installation, insulation effect is good; Guaranteed the safe operation of transformer, be worthy of popularization.
Description of drawings
Specify the utility model below in conjunction with accompanying drawing and embodiment;
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.
Embodiment:
Referring to Fig. 1 and Fig. 2, the transformer of present embodiment is used insulation pressing, comprises briquetting body 10, and this briquetting body 10 adopts 3240 epoxy materials to be made, and its thickness is 35mm, and width is 50mm, and length is 125mm.On briquetting body 10 upper surfaces, process oval-shaped fixing hole 11, this fixing hole length is 40mm, and the degree of depth is 5mm.Be provided with protruding chuck 12 in the lower surface of briquetting body 10, the protrusion length of this protruding chuck 12 is 20mm, and it is trapezoidal.
Be provided with the draw-in groove 121 that is used for fixing insulation board in the centre of said protruding chuck 12, the width of this draw-in groove 121 is 6mm, and is suitable with insulation board thickness.Be respectively equipped with high pressure boss 13 that is used for fixing high-tension coil and the low pressure boss 14 that is used for fixing low-voltage coil in protruding chuck 12 both sides.
For avoiding the collision between insulation pressing and the coil, on low pressure boss 14 and high pressure boss 13, be respectively equipped with rubber blanket 20, these rubber blanket 20 thickness are 5mm.
Present embodiment is fixed in the transformer in use, is used for fixing high-tension coil and low-voltage coil; Through protruding chuck 12 is set, make its isolated high-voltage coil and low-voltage coil, convenient fixedly high-tension coil and low-voltage coil position; Added high-tension coil and low-voltage coil insulation property, and made its stable installation, insulation effect is good; Guaranteed the safe operation of transformer, be worthy of popularization.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model protection defined by the appended claims and their equivalents defined
.
