Abstract

The utility model discloses a bus duct grounding member, comprising a metal casing used for fixing conducting bars and insulation liners used for separating each conducting bar. End portions of each conducting bar are in connection through metal connecting piece sets. The metal casing and the metal connecting piece sets are respectively provided with I-shaped metal mounting pieces. An opening side of each I-shaped metal mounting piece is in connection with the metal casing, and the other opening side of each I-shaped metal mounting piece is in connection through bus bars. The bus duct grounding member can be in connection with the metal casing and the metal connecting piece sets on a same side of a bus duct through the I-shaped metal mounting pieces and the bus bars, i.e., a strand of grounding wires composed of the bus bars and the metal casing are lead out from the metal connecting piece sets; meanwhile, the I-shaped metal mounting pieces can prevent the bus bars from loosening in use process and guarantee reliability of a bus duct structure.

Description

A kind of earthing member of bus duct
Technical field
The utility model relates to bus duct field, particularly a kind of earthing member for bus duct.
Background technology
Bus duct system is an efficient power distribution equipment of carrying electric current, be mainly used in the electric energy that modern high-rise building and large-scale workshop need to be huge, belong to the cable that substitutes in conventional art and crane span structure for power distribution equipment, by have multiple feeding interface on bus duct, for the power taking of diverse location, wherein also need at least one busbar to be connected as earth connection with metal shell.Because this earth connection is generally connected on outside, easily in use get loose, and this getting loose be difficult to find in time, cause serious potential safety hazard, be therefore necessary to design safer technology for this situation.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of safer bus duct earthing member.
The utility model solves the technical scheme that its technical problem adopts:
A kind of earthing member of bus duct, comprise for the metal shell of fixing busbar with for separating the insulating cell of each busbar, between the end of described each busbar, connect by metal connecting sheet group, in described metal shell and metal connecting sheet group, be respectively arranged with I-shaped shape metal installed part, wherein the open side of this I-shaped shape metal installed part is connected with metal shell, and the opposite side open side of described each I-shaped shape metal installed part connects by bus.
For the installation that facilitates I-shaped shape metal installed part is fixed, the lower ending opening side of described I-shaped shape metal installed part forms and connects base to two Edge Bends respectively, and described connection base is welded on the outer surface of metal shell.
The chance getting loose in order to reduce bus, narrows clamping bus in the middle of the upper end open side direction of described I-shaped shape metal installed part.
The beneficial effects of the utility model are: this bus duct earthing member can pass through in the same side of bus duct I-shaped shape metal installed part, bus connection metal shell and metal connecting sheet group, involve from metal connecting sheet group the earth connection that one is made up of bus and metal shell, the situation that the structure of I-shaped shape metal installed part also avoids bus in use to get loose simultaneously, ensures this bus duct reliability of structure.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is stereogram of the present utility model.
Embodiment
With reference to Fig. 1, a kind of earthing member of bus duct, comprise for the metal shell 2 of fixing busbar 1 with for separating the insulating cell 3 of each busbar 1, between the end of described each busbar 1, connect by metal connecting sheet group 4, be to be direct-connected between metal connecting sheet group 4 and busbar 1, specifically can connect by bolt.In described metal shell 2 and metal connecting sheet group 4, be respectively arranged with I-shaped shape metal installed part 5, wherein the open side of this I-shaped shape metal installed part 5 is connected with metal shell 2, the opposite side open side of described each I-shaped shape metal installed part 5 connects by bus 6, wherein the size of bus 6 does not need very greatly, and general volume ratio busbar 1 is much smaller.Bus 6 can adopt copper, aluminium or the manufacture of associated alloys material.Bus 6 is connected by spiral or rivet with I-shaped shape metal installed part 5.
The lower ending opening side of described I-shaped shape metal installed part 5 forms and connects base 51 to two Edge Bends respectively, and described connection base 51 is welded on the outer surface of metal shell 2, ensures the intensity of I-shaped shape metal installed part 5.
In the middle of the upper end open side direction of described I-shaped shape metal installed part 5, narrow and clamp bus 6, wherein narrow do not need too large, mainly for the vertical edge that ensures I-shaped shape metal installed part 5 can also can ensure the contact to bus 6 the bolt looseness in the situation that, avoid earthing failure.
According to above-mentioned principle, the utility model can also carry out suitable change and amendment to above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.Described in while accompanying drawing, also just to aid illustration the application's content, the details such as some parts, ratio wherein should not be construed as limiting the protection range of this patent.
Through facts have proved, the I-shaped shape metal installed part 5 of this bus duct earthing member coordinates bus 6, metal shell 2 and metal connecting sheet group 4 to form an earth connection, wherein the structure of I-shaped shape metal installed part 5 can ensure the stability of this earth connection, even if the bolt of bus 6 occurs loosening, I-shaped shape metal installed part 5 also can ensure that earth connection is effective, avoid bus duct to work in the situation that not knowing earthing failure, bring potential safety hazard.
