Abstract
The utility model relates to a bus unit connecting device in an electricity transmitting device, used for transmitting and distributing electricity. In order to cause the installation and the maintenance of the bus to be convenient and fast and have the advantages of low temperature rise, strong overload capacity and high safety, the utility model is characterized in that each phase of the electrical conductor in the bus unit connecting device is a copper bar clamp composed of two blocks of thick copper bars of a single layer; the thickness of the two blocks of thick copper bars is 1.2 to 1.7 times of the thickness of the copper bus; insulating plates are arranged between each electrical conductor and the outer side of the electrical conductor at intervals; one to two threaded bolt clamping device are positioned at the middle lines of the electrical conductor and the insulation plates of each phase. The utility model lowers the resistance of the connecting device, reduces temperature rise, and enhances the overload capacity with the advantages of fast and convenient installation, good dynamic performance and high safety.
Description
The utility model relates to the bus-bar unit connecting device that power transmission and distribution are used in a kind of transmission facility.
At present, extensively the bus unit connected mode that adopts mainly is direct overlapping mode, promptly in the end punching of bus busbar, directly overlap behind the die mould, alternate employing insulating barrier is worn the bolt that twined with insulation again and busbar is strained and fixed its installation procedure complexity, labour intensity is big, and degree of protection was low between bus connected.In addition, also has a kind of docking mode, by jockey connection bus unit, be that busbar butts up against on the electric conductor that is formed by connecting by the multi-layer thin copper sheet in the jockey, install more convenient, but the electric conductor of multi-layer thin copper sheet, increased it and shunk resistance, used temperature rise higher, overload capacity is low.
The purpose of this utility model provides a kind of installation, easy to maintenance, quick, uses temperature rise low simultaneously, and overload capacity is strong, safe and reliable bus-bar unit connecting device.
Bus-bar unit connecting device of the present utility model, comprise electric conductor, the bolt hold down gag of insulating barrier, it is characterized in that, one of described electric conductor is the copper bar folder that two single monolayer thick copper bars are formed mutually, the thickness of two copper bars is 1.2-1.7 times of copper busbar thickness, and insulation board is interval between each phase electric conductor and the electric conductor outside, 1-2 bolt hold down gag is arranged in each phase electric conductor and insulation board midline.A pair of spheric washer and a pair of flute profile pressing plate that each bolt hold down gag runs through the bolt of each phase electric conductor and insulation board by one and is positioned at the bolt two ends are formed, described spheric washer simultaneously is the plane, another side is a sphere, the one side on its plane is pressed on the insulation board in the electric conductor outside, and the flute profile pressing plate is pressed on the sphere of spheric washer by bolt.
The utility model has the advantages that, the thickness ratio of suitable electric conductor copper bar and bus, reduced the contraction resistance of jockey, reduced temperature rise, strengthened overload capacity, while is owing to the autoregulation of spheric washer structure in the bolt hold down gag, thrust can be added on the area planar equably, and the plane that conductor is asked when installing is closely contacted, and helps reducing contact resistance, reduce temperature rise, strengthen overload capacity, also make easy for installation, fast, the connected mode of butt joint also can be eliminated the longitudinal stress that produces when bus is installed in addition, make its dynamic property good, safe and reliable.
Provide an embodiment of the present utility model and accompanying drawing below:
Fig. 1 is a transversary cutaway view of the present utility model;
Fig. 2 is a user mode cutaway view of the present utility model.
As shown in the figure, the copper bar folder that its electric conductor 1 of bus-bar unit connecting device of the present utility model respectively is two copper bars 2 mutually, the thickness of two copper bars 2 be copper busbar 8 thickness that connected 1.2-1.7 doubly, between each phase electric conductor 1 and electric conductor outside all is separated with 3, two bolt hold down gags 4 of insulation board and is positioned at each phase electric conductor 1 and insulation board 3 midline.Each bolt hold down gag 4 has a bolt 5 that runs through each phase electric conductor 1 and insulation board 3, its a pair of flute profile pressing plate 6 by its two ends and a pair of spheric washer 7 compress each phase electric conductor 1 and the copper busbar 8 inserted respectively between the copper bar 2 from electric conductor 1 two ends, have just finished the connection of two sections bus unit.Spherical washer 7 inboards are the plane, and the outside is a sphere.
