Abstract
The utility model provides a large-current enclosed busbar straight-through CT structure. The large-current enclosed busbar straight-through CT structure comprises a shell body, wherein the shell body is of a cylindrical structure with one end open and the other end closed, coils are arranged outside the inner wall of the shell body, and epoxy resin is arranged between the outer wall of the shell body and the inner wall of the shell body. Due to the arrangement of the shell body, the defect that a single fixing mold has to be adopted for a traditional CT in the manufacturing process can be overcome, the CT manufacturing cost can be greatly reduced, and the production cycle can be shortened. Due to the fact that the coils are arranged inside the shell body and sealed through the epoxy resin in a poured mode, the coils can be effectively protected against collision in the installation and transportation process and the insulation performance is increased.
Description
Technical field
The utility model relates to a kind of punching CT structure, be specifically related to a kind of large electric current enclosed busbar punching CT structure, can be applicable to metal-enclosed bus or other transmission line system, generally be installed on the generator outlet sleeve pipe and isolated-phase enclosed bus in, belong to enclosed busbar manufacturing technology field.
Background technology
Traditional main type CT is to be formed by specific grinding tool cast by epoxy resin, the cost of manufacturing grinding tool is high, and can't adjust size according to the quantity of coil, when producing single or two coils, epoxy resin filling must be used in unnecessary grinding tool space, has so just caused the waste of material.While in CT, a plurality of coil being arranged, if in use single coil breaks down, whole CT must all replace, and caused so again the wasting of resources.The CT volume of traditional form is large, and weight is large, in the time of in being installed on enclosed busbar, to installment work, brings great inconvenience, and, after rule of thumb CT is installed in bus, in transportation, installs in the process of bus, very easily causes the damage of CT.Traditional binding-type CT, coil only has glass tape to be wound around, so collide with or water easily destroys the insulation of coil while drenching running into.
The utility model content
In order to make up the deficiencies in the prior art, the utility model provides a kind of large electric current enclosed busbar punching CT structure.
The utility model is by the following technical solutions:
A kind of large electric current enclosed busbar punching CT structure, comprise housing, and housing is that an end is uncovered, the tubular structure of other end sealing, and the inner walls peripheral hardware has coil, between housing outer wall and inwall, is provided with epoxy resin.
Preferably, it also comprises the lead terminal that is arranged on end winding.
Preferably, housing comprises shell, inner casing and bottom shrouding, and shell and inner casing arrange with one heart, and the bottom shrouding is arranged on outer casing bottom, and bottom shrouding upper surface is connected with inner shell bottom.
Preferably, the inner casing upper surface protrudes from the upper surface of shell.
Preferably, shell material is aluminium.
The beneficial effects of the utility model:
(1) setting of housing, can solve traditional CT and must adopt the drawback of single fixed mould in manufacture process, can greatly reduce the CT manufacturing cost, shortens the production cycle;
(2) coil is positioned in housing, and builds sealing with epoxy resin, can effectively protect coil do not collided with in the installation and transportation process and increase insulation property;
(3) the present invention is simple in structure, easily manufactured, can avoid the poor characteristics of traditional CT interchangeability according to on-the-spot actual demand adjusting size, as much as possible meets the on-the-spot cooperation demand of installing.
The accompanying drawing explanation
The master that Fig. 1 is the selected embodiment of the utility model looks schematic diagram.
The schematic top plan view that Fig. 2 is the selected embodiment of the utility model.
In figure 1, inner casing, 2, shell, 3, the bottom shrouding, 4, epoxy resin, 5, coil, 6, lead terminal.
Embodiment
Better understand the utility model for the ease of those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further details, following is only the exemplary protection range of the present utility model that do not limit.
With reference to accompanying drawing 1,2, a kind of large electric current enclosed busbar punching CT structure, comprise housing, and housing is that an end is uncovered, the tubular structure of other end sealing, and the inner walls peripheral hardware has coil 5, is provided with epoxy resin 4 between housing outer wall and inwall.
Consider easy for installationly, also comprise the lead terminal 6 that is arranged on coil 5 ends in the present embodiment.
The present embodiment middle shell comprises shell 2, inner casing 1 and bottom shrouding 3, and shell 2 and inner casing 1 arrange with one heart, and bottom shrouding 3 is arranged on shell 2 bottoms, and shrouding 3 upper surfaces in bottom are connected with inner shell bottom.
In the present embodiment, inner casing 1 upper surface protrudes from the upper surface of shell 2.
In the present embodiment, shell material is aluminium.
The utility model production process is as follows:
When manufacturing large electric current enclosed busbar punching CT structure, can first with aluminium sheet, do a housing, then coil 5 is positioned in housing, then epoxy resin 4 is placed in housing and pours into a mould, and pick out lead terminal 6.The large I of shell dimension is done according to the demand of on-the-spot actual installation.
Below only described basic principle of the present utility model and preferred implementation, those skilled in the art can make many changes and improvements according to foregoing description, and these changes and improvements should belong to protection range of the present utility model.
