The supporting insulator at least comprises an insulator (1) and a central connecting pipe (2), and is characterized in that a cylindrical pipe body is arranged in the middle of the insulator (1), three supporting columns (3) in integral pouring with the cylindrical pipe body are arranged along the outer surface of the cylindrical pipe body, are distributed evenly along the circumferential direction of the pipe body and are vertical to the outer surface of the pipe body, and the cylindrical pipe body of the insulator (1) sleeves on the central connecting pipe (2). According to the utility model, the situation can be guaranteed that the supporting insulator is contacted with the inner wall of a bus cylinder reliably, the connection of a bus conductor is relatively firm, an eddy current is prevented, at the same time, the supporting insulator can move freely inside the bus cylinder.
Description
Technical field
The utility model is particularly related to a kind of supporting insulator for high current power transmission equipment, belongs to electric power electric field.
Background technology
In GIB, according to electric pressure and structural requirement, existing supporting insulator adopts single insulator, and this supporting insulator is arranged on bus inner barrel, cannot be freely movable.Because the support column of supporting insulator only has one, support column top is plane simultaneously, can not reliably contact with casing cylinder inwall, easily produces floating potential.The insulator of this supporting insulator and center are taken over as integral type structure, and the caliber that center is taken over can not guarantee reliable contact with supporting insulator, and the caliber mobility scale that center is taken over is little.Wherein, GIB is the abbreviation of " Gas insulated transmission bus ", Chinese " gas-insulated transmission of electricity bus " by name.
Utility model content
The purpose of this utility model is exactly the problem in order to solve above-mentioned existence, a kind of support insulator of proposition, and it can guarantee that supporting insulator reliably contacts with the inwall of bus cylindrical shell, and bus-bars conductor is connected relatively
firmly, andprevent the generation of floating potential, can make supporting insulator move at bus cylindrical shell internal freedom simultaneously.
The technical solution of the utility model is: supporting insulator, and which comprises at least insulator and center and take over, it is characterized in that: in the middle of described insulator, for cylindrical shape body, have along the outer surface of cylindrical shape body to pour into it holistic support column; Support column is 3, and 3 support columns are uniformly distributed and vertical with the outer surface of body along the circumferencial direction of body; The cylindrical shape body of insulator is enclosed within center and takes over.
In 3 described support columns, one of them support column top is fluted, is vertically provided with spring in groove; The top of two other support column is provided with the supporting member of arc.
The material of described supporting member is metal material.
The beneficial effects of the utility model are: be along the circumferential direction uniformly distributed three support columns at the cylindrical shape body of insulator, wherein two support column tops adopt fixing sphere design, another support column adopts telescopic spring structure, can adjust supporting insulator circumscribed circle, guarantee that supporting insulator reliably contacts with bus cylinder inboard wall, bus-bars conductor is connected relatively
firmly,prevent that floating potential from producing, and can make supporting insulator move at bus cylindrical shell internal freedom simultaneously.In addition, the cylindrical shape body of insulator is enclosed within center and takes over, the metal tube that can adopt as required different inner diameters is taken at center, center is taken over can be enclosed within different tube diameters conductor outside, can move freely, at correct position, supporting insulator and bus-bars conductor are fixed to connection by drilling; Can guarantee so the flexible control to bus cylindrical shell inside conductor support zone.Supporting insulator of the present utility model is simple in structure, and insulation property meet the demands, easy for installation.
Below in conjunction with drawings and Examples, the utility model is further described, but not as to restriction of the present utility model.
Accompanying drawing explanation

Fig. 2 is the supporting insulator end view of the utility model embodiment;
Fig. 3 be the utility model embodiment for supporting insulator cutaway view.
In figure: 1, insulator; 2, center is taken over; 3, support column; 4, supporting member; 5, groove; 6, spring.
Embodiment
As shown in Figure 1 and Figure 2: supporting insulator, which comprises at least insulator 1 and center and take over 2, in the middle of described insulator 1, be cylindrical shape body, have and pour into it holistic support column 3 along the outer surface of cylindrical shape body; Support column 3 is 3, and 3 support columns 3 are uniformly distributed and vertical with the outer surface of body along the circumferencial direction of body; The cylindrical shape body of insulator 1 is enclosed within center and takes on 2.
On the basis of embodiment 1, as shown in Figure 3: in 3 described support columns 3, one of them support column 3 upper end is fluted 5, at the interior spring 6 that is vertically provided with of groove 5; The top of two other support column 3 is provided with the supporting member 4 of arc.The material of described supporting member 4 is metal material.The metallic support of arc 4 can facilitate supporting insulator to move at bus cylindrical shell.
The utility model supporting insulator is in the time that supporting insulator contacts with bus cylindrical shell, the spring free-extension of support column, support column relative position that can appropriate change supporting insulator, adapts to cylinder inboard wall deviation in roundness, guarantee that it reliably contacts, bus-bars conductor is connected relatively
firmly,prevent that floating potential from producing, and can make supporting insulator move at bus cylindrical shell internal freedom simultaneously.According to the conductor of different tube diameters, select the center adapter of corresponding supporting insulator to be enclosed within conductor outside, can move freely, at correct position, supporting insulator and bus-bars conductor are fixed to connection by drilling, can guarantee so the flexible control to bus cylindrical shell inside conductor support zone.The metal tube that can adopt as required different inner diameters is taken at center.
The parts that the present embodiment does not describe in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
