Abstract
The utility model belongs to transmission equipment, and relates to an integrated grounding structure of a full-shielding tubular bus. The structure comprises a plurality of sections of tubular buses with a plurality of insulating layers, and all sections of the tubular buses are connected with one another by a plurality of interfaces; the periphery of the insulating layer of each section of the tubular bus is sheathed with a shielding layer which is made from a whole thin-wall copper pipe or aluminum pipe, the periphery of each shielding layer is sheathed with an external insulating layer, and the end of each insulating layer which is arranged in each interface is connected with a grounding hoop; and each interface comprises a shielding cylinder which is sheathed at the periphery of a bus connecting part, the shielding cylinder is internally provided with an internally insulating layer and is supported by an insulating block, and the inner wall of the shielding cylinder is connected with the hoop by an electric connecting piece. The structure is simple, is high in grounding reliability, and can prevent vortex from being generated by an electromagnetic field to heat up the peripheral equipment, and reduce the transmission losses.
Description
Technical field
The utility model belongs to transmission facility, relates to a kind of full-shield tubular bus integral ground structure that is used for the tubular bus external insulation is carried out integral ground.
Background technology
Existing tubular bus with insulating barrier generally includes the external insulation layer of tubular conductor, the ground connection of its external insulation layer is that a plurality of earth terminals are set on the length direction of one section tubular bus, carry out ground connection by aerial lug then, its not only fitting operation inconvenience, and poor reliability also is not easy to each section bus and busbar joint and carries out integral ground.
Summary of the invention
Technical problem to be solved in the utility model provides the full-shield tubular bus integral ground structure that a kind of simple in structure, ground connection is convenient, reliability is high.
Full-shield tubular bus integral ground structure of the present utility model comprises that multistage has the tubular bus of insulating barrier, connects by joint between each section tubular bus; The insulating barrier periphery of each section tubular bus is with the screen of being made by whole thin-wall copper pipe or aluminium tube material, is with external insulation sleeve in the screen periphery, and the part that is positioned at joint in the screen end is connected with the ground connection anchor ear; Described joint comprises a shielding cylinder that is enclosed within periphery, bus coupling part, and the shielding cylinder inboard is provided with inner insulating layer and supports by collets, and the inwall of shielding cylinder is connected with above-mentioned ground connection anchor ear by conducting connecting part.
The utility model is by the be connected integral ground that can easily realize bus-bar system overall length direction on of integrally-built screen with shielding cylinder, and it is simple in structure, ground connection reliability height; In addition, screen and shielding cylinder also play the effect of shielding bus built-in field in as earthing conductor, can avoid electromagnetic field that surrounding devices is produced eddy-current heating, have also reduced transmission losses.
