A kind of joint design of tube type bus groove conductor
Technical field
The utility model belongs to power transmission and distribution technical field, is specifically related to a kind of joint design of tube type bus groove conductor.
Background technology
The conductor of tube type bus groove, mainly using cast conductor as the transmission medium of electric energy, is connected to become urgent problem between tube type bus groove.Current most of bus duct product is all based on rectangular conductor, namely the connectivity problem between conductor can be solved by plane contact, cast conductor is cambered surface, as incomplete in adopted the cambered surface way of contact very likely to there will be contact-making surface, contact is little, FS final spice location contacts resistance increases, and conductor joint heating is excessive, so that joint burns.
Utility model content
In order to overcome above-mentioned prior art Problems existing, the utility model provides a kind of efficient output short circuit protection circuit, facilitates the connection between cast conductor, improves the reliability of joint area and the stability of product.
The technical solution adopted in the utility model is: a kind of joint design of tube type bus groove conductor, comprise pipeline link and terminal end, described pipeline link is " θ " type structure, described terminal end is H type structure, described terminal end and pipeline link are structure as a whole, and upper and lower circular arc portion is removed by machining by described terminal end vertically, retain mid-plane and partial arc, form one end " H " type, described mid-plane arranges screw.
Further, described pipeline link and pipeline conductor connection arrange chamfering.
Further, between described pipeline link and pipeline conductor for being welded to connect.
The beneficial effects of the utility model are:
1, cast conductor is converted to conventional planar to connect, simplify connected mode;
2, the contact area that two-sided overlap joint increases connecting portion can be carried out, reduce contact resistance, reduce line loss;
3, the resistance to short-circuit capacity of joint area is strengthened;
4, the connection between joint and joint is simplified.
Accompanying drawing explanation
Fig. 1 is the junction composition of the tube type bus conductor that the utility model proposes;
Fig. 2 is the tube type bus conductor tab structure and pipeline johning knot composition that the utility model proposes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
See Fig. 1 and Fig. 2, wherein Fig. 1 is the junction composition of the tube type bus conductor that the utility model proposes;
Fig. 2 is the tube type bus conductor tab structure and pipeline johning knot composition that the utility model proposes.
As depicted in figs. 1 and 2, a kind of joint design of tube type bus groove conductor, comprise: pipeline link 1 and terminal end 2, described pipeline link 1 is " θ " type structure, and described terminal end 2 is H type structure, and described terminal end 2 is structure as a whole with pipeline link 1, upper and lower circular arc portion is removed by machining by described terminal end 2 vertically, retain mid-plane 4 and partial arc, form one end " H " type, described mid-plane 4 arranges screw 5.
Further, described pipeline link 1 arranges chamfering 3 with pipeline conductor 6 junction.
Further, between described pipeline link 1 and pipeline conductor 6 for being welded to connect.
In the utility model embodiment, tube type bus trough connection structure is become by welding manner tube connector conductor combination after " θ " type chamfer of pipeline link, by the screw of terminal end, wire is fixed in mid-plane, due to conductive contact is planar structure, be that face contacts with wire connecting ends, overcome the problem that the direct contact-making surface caused be connected with pipeline is incomplete, cast conductor is converted to conventional planar and connect, simplify connected mode; The contact area that two-sided overlap joint increases connecting portion can be carried out, reduce contact resistance, reduce line loss; The both sides circular arc of mid-plane can be gathered terminal simultaneously, prevents terminal from exposing and is short-circuited with All other routes.
The conductor tab that the utility model provides is easy to connect, mechanical strength is high, strengthen the resistance to short-circuit capacity of joint area; Simplify the connection between joint and joint, and conductor can be prevented to be out of shape.
Above the utility model is described in detail, but the utility model is not limited to above-mentioned execution mode, in the ken that those of ordinary skill in the art possess, can also makes a variety of changes under the prerequisite not departing from the utility model aim.Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific execution mode, scope of the present utility model is defined by the following claims.
