Abstract
The utility model discloses a casing pipe type connection device of a bus duct, which comprises a bolt and two insulation boards, and is characterized in that three insulation partition boards distributed at intervals are arranged between the two insulation boards; the center of the board surface of each of the insulation partition boards and insulation boards is provided with a through hole; the bolt penetrates through the through holes of the insulation partition boards and insulation boards and is fixed by a nut; a casing pipe is disposed on the periphery of the bolt; butterfly elastic washers are arranged between the bolt and the insulation boards and between the nut and the insulation boards; partition bushings are arranged between the insulation partition boards and the insulation boards and among the insulation partition boards; and the partition bushings are sleeved on the casing pipe. The casing pipe type connection device of a bus duct is convenient to install, leads insulation performance among busbars of each phase to be better, and is safer and more reliable in use. Besides, the insulation partition boards do not need to be produced by designing special molds, and safe electricity transmission distance and electric clearance are guaranteed through insulation of the partition bushings and the casing pipe to the busbars of each phase.
Description
Technical field
The utility model relates to a kind of bus duct jockey, specifically is a kind of bushing type jockey of bus duct.
Background technology
Plug type bus duct arises at the historic moment as a kind of novel distribution lead, and bus duct system is an efficient power distribution equipment of carrying electric current, has especially adapted to the needs of more and more higher building and large-scale plant economical rationality distribution.Compare with traditional cable, the volume that demonstrates fully it when big electric current is carried is little, capacity big, the design and construction cycle short, mounting or dismounting make things convenient for, can not burn, the characteristics of safe and reliable, long service life.The bus duct product is applicable to and exchanges 50Hz, rated voltage 380V, and the three-phase and four-line of rated current 250A-4000A is in the three-phase four-wire system power supply-distribution system engineering.
Bus duct is connected with the bus duct of some special requirement and being connected of special power distribution cabinet outlet, because its structure space is tight, the special circumstances that can't adopt usual manner to connect, need specialized designs to go out the bushing type jockey, if adopt the jockey of existing bus duct, it is very inconvenient that it installs connection.
The utility model content
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of bushing type jockey of being convenient to install connection, safe and reliable bus duct.
To achieve these goals, the technical solution adopted in the utility model is: the bushing type jockey of bus duct, include bolt and two insulation boards, it is characterized in that: be provided with three insulating barriers spaced apart between described two insulation boards, the plate face center of described insulation board and insulating barrier has through hole, described bolt passes from the through hole of insulation board and insulating barrier, and fixes with nut; The periphery of bolt is provided with sleeve pipe.
Described screw bolt and nut respectively and be provided with the butterfly elastic washer between the insulation board.
Be provided with spacer between described insulating barrier and the insulation board and between insulating barrier and the insulating barrier, described spacer is socketed on the sleeve pipe.
Described sleeve pipe and spacer are to be made by the soft rubber of good insulation preformance.
The beneficial effects of the utility model: not only easy for installation owing to adopt the bushing type jockey of bus duct, and make between each phase busbar insulating properties better, safety and reliability in the use; In addition, the insulating barrier in the utility model does not need to design special dies manufacturing, to each insulation of busbar mutually, has guaranteed safe transmission distance and electric clearance by spacer and sleeve pipe.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an end view shown in Figure 1.
Among the figure: 1, Electric Appliance Cabinet power supply output busbar; 2, insulating barrier; 3, bolt; 4, sleeve pipe; 5, insulation board; 6, butterfly elastic washer; 7, spacer; 8, transmission line busbar; 9, nut.
Embodiment
As shown in Figure 1, 2, the bushing type jockey of bus duct, include bolt 3 and two insulation boards 5, it is characterized in that: be provided with three insulating barriers spaced apart 2 between described two insulation boards 5, the plate face center of described insulation board 5 and insulating barrier 2 has through hole, described bolt 3 passes from the through hole of insulation board 5 and insulating barrier 2, and fixing with nut 9; The periphery of described bolt 3 is provided with sleeve pipe 4.
Described bolt 3 and nut 9 are respectively and be provided with butterfly elastic washer 6 between the insulation board 5.
Be provided with spacer 7 between described insulating barrier 2 and the insulation board 5 and between insulating barrier 2 and the insulating barrier 2, described spacer 7 is socketed on the sleeve pipe 4.Described sleeve pipe 4 and spacer 7 are to be made by the soft rubber of good insulation preformance.
Operation principle: when using the bushing type jockey of bus duct, earlier nut is twisted, remove the insulation board of nut one side, and then remove spacer 7 and insulating barrier 2, when having only a spacer 7, periphery at spacer 7 is interted in hole on row's face of one end of transmission line busbar 8, after this phase transmission line busbar 8 is loaded onto, refill and load onto insulating barrier 2 and spacer 7 successively, continue other each phase transmission line busbar 8 of dress, after all transmission line busbars 8 install, load onto insulation board 5 and butterfly elastic washer 6 at last, again each of Electric Appliance Cabinet power supply output busbar 1 exported mutually busbar and inserted in the space between the insulating barrier 2, and fix with nut 9.
Owing to adopt the bushing type jockey of bus duct, not only easy for installation, and make between each phase busbar insulating properties better, safety and reliability in the use; In addition, the insulating barrier in the utility model does not need to design special dies manufacturing, to each insulation of busbar mutually, has guaranteed safe transmission distance and electric clearance by spacer and sleeve pipe.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; 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 changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
