Description
One, technical field
The present invention relates to a kind of attachment devices, especially a kind of attachment device for insulating tube type busbar end.
Two, background technology
In order to meet big main transformer capacity transformer low-pressure side inlet wire big rated current needs, due to insulating tube type
Busbar have current-carrying capacity is big, kelvin effect is low, warm liter is low, good insulation preformance, good heat dissipation, the technical performance of high mechanical strength, replace
Generation rectangular bus bar and bare bus bar, in the low-pressure side inlet wire installation process of transformer, due to insulating tube type busbar limited length,
It needs two insulating tube type busbars being attached, the attachment device for being accordingly used in insulating tube type busbar end is important cable
Attachment, in a kind of existing attachment device for insulating tube type busbar end, connection type has following：
First, mode is flattened in tube type bus end, cast conductor is flattened into tabular, is then overlapped with other busbares
Plate and bolt are attached, and since phenomena such as uneven platen surface, tablet side cracking often occurs in the mode of flattening, are caused
Effective faying surface is insufficient, cannot be satisfied the demand of current-carrying capacity, leads to joint fever, the big problem of partial discharge quantity；
Second is that built-in connection type, busbar both ends are inserted by outer diameter connecting tube identical with insulating tube type busbar internal diameter,
End of bus bars axially cracks, and is thus attached transmission electric current, such connection type is since end of bus bars cracks, as shaken
Dynamic, faying surface becomes smaller or virtual connection phenomenon, causes poor contact, Wen Shenghui higher；
Third, external connection type, connecting tube is made of symmetrical two parts semicircle, carries engaging lug and threaded hole, interior
Diameter is consistent with insulating tube type busbar outer diameter, by connecting two busbar docking connecting tubes and the bolt mode of being fixedly clamped
It connects, since engaging lug protrudes busbar, electric field can be caused uneven, be easy to cause electric field stress herein and concentrate and breakdown occurs now
As the switching performance of insulating tube type busbar end cannot be met；
Fourth, welded type, this mode is high to the technology requirement of welder, installation is complicated, weld bond resistance is big, weld bond is easy
Fracture；
Fifth, insulating tube type busbar end conductor is flattened at platen surface mode, with other tube type bus platen surface lapping plates
Phenomena such as being attached with bolt, flattening planar surface out-of-flatness, tablet two sides cracking, causes effective faying surface insufficient, nothing
Method meets the needs of current-carrying capacity, leads to problems such as joint fever, partial discharge quantity big；
Sixth, hood type connects, anchor ear is formed by carrying engaging lug and the symmetrical two parts semicircle of threaded hole, passes through spiral shell
The bolt mode of being fixedly clamped is attached, and since engaging lug protrudes busbar, electric field can be caused uneven, electric field herein is be easy to cause and answer
Power is concentrated and punch-through occurs.
