Abstract
The utility model discloses a busway earthing device comprising a busway and connecting elements connected with the busway, wherein the busway and the connecting elements are all provided with metal casings. The surface of the same side or the two sides of the metal casings is connected with conduction metal strips fixing the busway and the connecting elements. The conduction metal strips are fastened on the metal bulges of the metal casings of the busway and the connecting elements by fastening pieces which are bolts. Metal bulges are provided with threaded holes matched with the bolts and are fixed to the cover plates of the busway and the connecting elements in a welding mode. The utility model has the advantages of tight combination and low cost, and the busway can effectively decrease the consumption of non-ferrous noble metal, such as copper or aluminium, etc.
Description
Technical field
The utility model relates to a kind of earthing device, and particularly a kind of aluminium alloy extrusions that adopts is made the bus groove case bus duct earthing device of double as protective earthing PE main line again.
Background technology
At present, a kind of three-phase five-wire mode bus duct is arranged both at home and abroad, five copper or aluminium matter electric conductors run through between whole bus duct as conduction electricity row, wherein, have a conduction electricity row to be connected the main line as ground connection PE with shell, prevent outer casing electrification.Yet the amount that this bus duct consumes coloured noble metals such as copper or aluminium is bigger, and cost is higher, is unfavorable for applying.
Summary of the invention
In order to overcome the above prior art deficiency; the utility model provide a kind of adopt shape do bus groove case again double as protective earthing PE main line, in conjunction with firm bus duct earthing device; the amount of coloured noble metals such as this bus duct consumption copper or aluminium is fewer; cost is lower, and is beneficial to and applies.
The technical scheme that its technical problem that solves the utility model adopts is: the bus duct earthing device, the connector that comprises bus duct and connection bus groove, described bus duct and connector all contain metal shell, it is characterized in that: the same side of described metal shell or both side surface are connected with the fixedly conductiving metal strip of bus duct and connector.
As further improvement of the utility model, described conductiving metal strip is fixed on by securing member on the metal coupling of metal shell of bus duct and connector.
As further improvement of the utility model, described securing member is a bolt, has the screw that matches with bolt on the metal coupling.
As further improvement of the utility model, described metal coupling is fixed by welding on the cover plate of bus duct and connector.
The beneficial effects of the utility model are: because the same side of described metal shell or both side surface are connected with the fixedly conductiving metal strip of bus duct and connector, ground connection PE main line is made up of metal shell and conductiving metal strip, therefore described bus duct can adopt the structure of three-phase four-wire system, thereby saved the copper bar or the aluminium row of a conduction, saved production cost; And, therefore the utlity model has well-set advantage because wire casing is connected by conductiving metal strip with connector.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that bus duct is connected with connector.
Embodiment
With reference to Fig. 1, Fig. 2, the bus duct earthing device comprises bus duct 1 and connector 2, and described bus duct 1 all contains metal shell 3 with connector 2, and the same side of described metal shell 3 or both side surface are connected with the fixedly conductiving metal strip 4 of bus duct 1 and connector 2.The volume of conductiving metal strip 4 is far smaller than copper bar or aluminium row.As long as the electricity of the every phase of bus duct row conductive contact 11 is placed between the adjacent connector conducting metal piece 12, fix by bolt 13 then and just can form the whole piece bus duct.Described bus duct 1 adopts three-phase four-wire system, thereby has saved the copper bar or the aluminium row of a conduction, has saved production cost; And, therefore the utlity model has well-set advantage because wire casing is connected by conductiving metal strip with connector.Described conductiving metal strip 4 can be conductors such as copper bar, aluminum strip or its alloy.
Wherein, described conductiving metal strip 4 is fixed on by securing member 5 on the metal coupling 6 of metal shell 3 of bus duct 1 and connector 2, described securing member 5 is a bolt, have the screw that matches with bolt on the metal coupling 6, described metal coupling 6 is fixed by welding on the cover plate 8 of bus duct 1 and connector 2.
Certainly, whether conductiving metal strip 4 can adopt modes such as riveted joint, welding to be fixed on the metal shell 3 of bus duct 1 and connector 2, no matter have metal coupling 6 to be connected with it and also belong to protection range of the present utility model.
Claims (4)
