Abstract
The utility model relates to a compound insulation electric conducting rod assembly of a line-outgoing bushing, which is characterized by comprising a cover plate; a cylindrical blind hole is arranged at the bottom surface of the cover plate, and an electric conducting rod is fixedly connected into the blind hole; after being heated by the cover plate, the electric conducting rod is in interference arrangement in the blind hole and is welded on to the cover plate. The utility model utilizes the mechanical matching between the cover plate and the electric conducting rod to enable the electric conducting rod assembly to have the characteristic of very low contact resistance, solves the problem that the temperature the bushing is increased due to the contact resistance when electric current passes through the bushing and can be widely applied to various high-voltage devices.
Description
Technical field
The utility model relates to a kind of electric installation, particularly about a kind of compound inslation outlet sleeve pipe conducting rod assembly.
Background technology
The main effect of compound inslation outlet sleeve pipe conducting rod assembly is that the high-potential voltage of electric wire or cable is introduced among the GIS (metal all-closed formula combined electrical apparatus), so that finish the operations such as divide-shut brake to high-potential voltage on the working line.Compound inslation outlet sleeve pipe conducting rod assembly has the taper fit mode (as shown in Figure 2) of employing in the prior art, and this mode comprises upper flange 1, and the taper machined surface of upper flange 1 bottom is directly pegged graft fixing by the aluminium pin 2 and the taper machined surface on guide rod 3 tops.Two taper machined surfaces of taper fit mode must manufacture, otherwise be difficult to guarantee the fully effectively contact of two metal coverings, contacting the bad contact-making surface resistance that will make increases, cause temperature too high, threaten the operation of sleeve pipe long-term safety, particularly because compound inslation outlet inside pipe casing is full of SF6 gas, if place the conducting rod assembly contact resistance of SF6 gas excessive, when by big electric current, bushing temperature constantly raises, the long-term safety stable operation reliability of circuit will be influenced, the drawback of bushing explosion accident can be caused when serious.The difficulty of the processing of taper machined surface and assembling is also bigger in addition.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of have low contact resistance characteristic, safe and reliable compound inslation outlet sleeve pipe conducting rod assembly.
For achieving the above object, the utility model is taked following technical scheme: a kind of compound inslation outlet sleeve pipe conducting rod assembly, it is characterized in that: it comprises a cover plate, is provided with a blind cylindrical hole in described cover plate bottom surface, a fixedly connected conducting rod in described blind hole.
Described conducting rod is arranged in the described blind hole by cover plate heating back interference, and by being welded to connect on described cover plate.
The utility model is owing to take above technical scheme, and it has the following advantages: 1, the utility model utilizes the mechanical engagement between cover plate and the conducting rod, makes the conducting rod assembly have the very characteristic of low contact resistance.2, the utility model utilizes the mechanical engagement between cover plate and the conducting rod, and when having solved sleeve pipe by big electric current, problem is increased in the sleeve pipe temperature rise that contact resistance causes.3, the utility model compound inslation outlet sleeve pipe conducting rod assembly can be introduced the high-potential voltage of electric wire or cable among the GIS safely and effectively, and the utility model can be widely used in the various high-tension apparatuses.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises a cover plate 1, is provided with a blind cylindrical hole 2 in cover plate 1 bottom surface, connects a conducting rod 3 at blind hole 2 internal fixation.
The utility model adds man-hour, at first in open-blind hole, cover plate 1 bottom surface 2, by heating cover plate 1 cylindrical hole 2 is expanded then after, conducting rod 3 is inserted in the blind hole 2 of cover plates 1, after the cooling, conducting rod 3 is welded on the cover plate 1 again.
When the utility model uses, flange on the composite sheath that cover plate 1 and compound insulation sleeve is effective couples together by bolt, the current-carrying part among the GIS is inserted in conducting rod 3 bottom surfaces, in the compound insulating sleeve running, high-potential voltage conducts to conducting rod 3 by cover plate 1, conduct to the current-carrying part of GIS inside by conducting rod 3, thereby realize high-potential voltage is introduced among the GIS safely and effectively.In the utility model, the interference fit of cover plate 1 and conducting rod 3 has guaranteed that with the way of contact cover plate 1 contacts with the tight of conducting rod 3, greatly reduce the contact resistance of conducting rod assembly, solved when sleeve pipe passes through big electric current, problem is increased in the sleeve pipe temperature rise that contact resistance causes.
In the various embodiments described above, can also there be other to change with being connected,, should do not get rid of outside protection range of the present utility model based on the changes and improvements on the technical solutions of the utility model in structure.
