Description
Technical field
The utility model belongs to power transmission and distribution field, relates to a kind of compact bus duct casing earthing device.
Background technology
In prior art, the mode of compact bus duct casing ground connection is: on aluminum alloy casing, rivet grounding nut, install earth stud on grounding nut additional, then connect with copper conductor.The problem existing is: grounding nut need be riveted on aluminum alloy casing, fragile when producing and install.Secondly grounding nut is with aluminum alloy casing contact area is little, line nose and the grounding nut contact area of earth connection are also little, and the reliability of conducting electricity is lower.And the contact-making surface place of grounding nut, earth stud needs plastic-blasting, easily insulation, the conduction of destroying grounding nut and earth stud is connected, and does not have the object of the bus duct earthing of casing.
Summary of the invention
Problem to be solved in the utility model is, provides a kind of and can guarantee compact bus duct casing Earthing Reliability, compact bus duct casing earthing device simple in structure, easy for installation.
The technical solution of the utility model is, a kind of compact bus duct casing earthing device comprises bus duct, connects connector, the earth lead of adjacent two sections of bus ducts, and described bus duct comprises upper cover plate and lower cover; Be positioned at the upper cover plate at described bus duct link place and the outer surface of lower cover and be separately installed with the plug being made by electric conducting material, described plug is connected with the shell conduction of bus duct; Described connector links together two sections of bus ducts by the plug on adjacent two sections of bus ducts; The line nose of described earth lead is arranged on the end face of plug by installed part, and is connected with plug conduction.
Described installed part is bolt, is provided with the screwed hole matching with described bolt on the end face of described plug.
On the end face of described plug, be provided with a plurality of screwed holes.
Described earth lead includes two line noses, and two line noses of described earth lead are arranged on respectively on the end face of plug of adjacent two sections of bus ducts.
The utility model has the advantages that, 1. earth point is arranged on plug, production technology is simple, easy for installation.2. because plug surface is through anti-oxidant treatment, electric conductivity is good, and the bus duct shell of its position just taked to prohibit spray measure originally, has guaranteed the reliability of earth point ground connection.3. two of earth lead line noses are connected on the plug of adjacent two sections of bus ducts, disposable can be by two sections of bus duct earthings of casing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing at A place in Fig. 1.
Fig. 3 is the fractionation schematic diagram of plug of the present utility model and bus duct.
Fig. 4 is the enlarged drawing at B place in Fig. 3.
Embodiment
A compact bus duct casing earthing device, comprises bus duct 1, connects connector 2, the earth lead 5 of adjacent two sections of bus ducts 1, and described bus duct 1 comprises upper cover plate 11 and lower cover 12; Be positioned at the upper cover plate 11 at described bus duct 1 link place and the outer surface of lower cover 12 is separately installed with the plug 4 being made by electric conducting material.
As shown in Figure 4, on described plug 4, be provided with two screwed holes that connect its upper and lower surface, on described bus duct 1 and connector 2, be respectively arranged with the through hole matching with screwed hole on described plug 4, by bolt, bus duct 1, plug 4, connector 2 connected together.The shell conductive contact of the bottom surface of described plug and bus duct 1; Described connector 2 links together two sections of bus ducts 1 by the plug 4 at adjacent two sections of bus duct 1 link places.
As shown in Figure 2, the line nose of described earth lead 5 is arranged on the end face of plug 4 by installed part 6, and is connected with plug 4 conductions.
Described installed part 6 is hexagon socket head cap screw, is provided with the screwed hole 3 matching with described bolt on the end face of described plug 4.
On the end face of described plug 4, be provided with two screwed holes 3.
Described earth lead 5 includes two line noses, and two line noses of described earth lead 5 are arranged on respectively on the end face of plug 4 of adjacent two sections of bus ducts 1.Choose again a longer earth lead 5, the arbitrary line nose of line nose and the above of longer earth lead 5 is connected together, then by 1 while of two sections of bus ducts ground connection.
