Abstract
The utility model relates to the field of high voltage electric power. The utility model belongs to a current measuring and protecting high voltage current transformer in an electric network of 35KV and above. The utility model is composed of wiring terminals, a coupler, a U type sleeve, a second winding and a box body. An insulating support which plays a fixing function is connected to the middle part of two arms of the U type sleeve, and the stability of the integral structure of the utility model is raised effectively.
Description
Technical field
The utility model relates to the high-tension electricity field, belongs to current measurement and the high-tension current inductor of protecting usefulness in a kind of 35KV and the above electrical network.
Background technology
The Dry Type High Tension Current Transformer that existing in the market a kind of interior external insulation is made for the organic synthesis material is a suit secondary winding in the ground of U molded cannula screen part, so the U molded cannula only reaches in its end and the junction of casing has fixing.Under the stressed and electrodynamic effect of binding post, the integrally-built stability of high-tension current inductor is reduced in the use, influenced the life-span of product.
The utility model content
The purpose of this utility model provides the more firm Dry Type High Tension Current Transformer of a kind of overall structure.
The purpose of this utility model is to realize like this, by the Dry Type High Tension Current Transformer that binding post, coupling, U molded cannula, secondary winding and casing are formed, also be included in the insulation that has had fixation to be connected in U molded cannula two arms middle part between casing and the connector and support.Insulation is supported for the rigidity plate of integrative-structure, also can be the connecting plate of split structure.Insulation is supported for single, also can be many.
The utility model has the advantages that the shortcoming that has overcome the overall structure mechanical robustness difference that existing Dry Type High Tension Current Transformer brings because of the defective of U molded cannula on fixing.

Embodiment
Below in conjunction with the embodiments the utility model is described further with reference to the accompanying drawings.
Embodiment 1
By the Dry Type High Tension Current Transformer that binding post 1, coupling 2, U molded cannula 3, insulation support 4, secondary winding 5 and casing 6 are formed, secondary winding 5 is sleeved on the ground screen part of U molded cannula 3, and fixedly secures with casing 6.Coupling 2 is the members that connect between 3 two terminals of U molded cannula, has certain mechanical strength.One thoroughly does away with edge supports the 4 rigidity plates that are structure as a whole, and the middle part of 3 liang of arms of U molded cannula is fixed at two ends, between casing 6 and coupling 2.
Embodiment 2
It is two that insulation supports 4, and one thoroughly does away with edge supports the 4 rigidity plates that are structure as a whole, and the middle part of going up of 3 liang of arms of U molded cannula is fixed at its two ends; Another thoroughly does away with edge and supports 4 for dividing the connecting plate of body structure, and the following middle part of 3 liang of arms of U molded cannula is fixed at its two ends, and the structure of remainder is identical with embodiment 1.
Embodiment 3
Insulation supports 4 can also be many, and present embodiment is that insulation is supported for 3 situation, wherein one thoroughly does away with edge support 4 for dividing the connecting plate of body structure, and the middle part of 3 liang of arms of U molded cannula is fixed at its two ends; Two thoroughly do away with the edge support 4 rigidity plates that are structure as a whole in addition, its two ends are individually fixed in the middle part of the going up of 3 liang of arms of U molded cannula and down, the structure of remainder is identical with embodiment 1.
