Description
Technical field
The utility model patent " bus main line bending unit joint connector " relates to vertical curve bus duct Installation Technology field.
Background technology
Bus duct as the power transmission and distribution mains system of long distance, to need bus main line unit constantly by the connection conducting of joint connector by power delivery to required place.Bus main line cell translation direction can be met when installing at the scene, on former direction, change 90 by bus duct
0.
In bus duct industry, traditional method is by two pieces of busbars at a right angle 90 by argon arc welding mode
0weld conversion direction afterwards.
Its Problems existing is:
1, by the copper bar that argon arc welding is welded, occur the quality problems of the not weld penetration be invisible to the naked eye sometimes, serious meeting has influence on electric conductivity.
2, through the busbar surface of argon arc welding welding, the polishing deburring that polishes flat must be carried out, polishing rear surface is protruded or out-of-flatness all can affect the assembling of bus unit, and dented meeting of polishing causes the sectional area of this place's busbar to reduce, jagged, can puncture to hold insulation and cause withstand voltage puncturing.
3, the length of vertical curve bus unit generally can not more than 500mm, because slight angular deviation can be a firing angle when welding, bending bus unit length is longer, then angular deviation is larger, very large error can be caused during installation, bus main line unit cannot be connected.
For this reason, the vertical curve unit of bus duct how is made neither can to change 90 again by welding manner
0direction, installs not only side at the scene and makes simple and direct but also can safe and reliablely be problem involved by the utility model patent.
Utility model content
Want to overcome above-mentioned existing problems, make bus main line bending unit when not turning to 90 by when welding manner
0in-site installation can be facilitated safe and reliablely to reach every technical performance index again, and the utility model bus main line bending unit joint connector is when guaranteeing that current-carrying cross section that joint connects copper bar allows to make by the method for right angled isosceles triangle arrangement perforate by adopting when temperature rise to connect on copper bar and joint steel clamp plate at splice insulation plate, joint.Two side right-angle sides of right angled isosceles triangle are the directions of bus main line unit insertion at a right angle, and use punching bolt firmly to be compressed by the busbar of dish-shaped bullet pad pressing plate, dish-shaped bullet pad, joint steel clamp plate, joint connection copper bar and bus main line unit.
The design primary structure of bus main line bending unit joint connector has: joint steel clamp plate, dish-shaped bullet pad, dish-shaped bullet pad pressing plate, insulating sleeve, splice insulation plate, joint connect copper bar, connect row's square hole cross-over block and punching bolt eight part composition.
The F893 epoxy glass cloth laminated board processing and fabricating that splice insulation plate adopts the withstand voltage moisture-proof conductive coefficient of thick 4mm all excellent, the square hole size that splice insulation plate is opened is identical with insulating sleeve overall dimension, structure can lead to permanent joint insulation board position, material can make bus duct anti-condensation in wet environment, the rapid heat dissipation when high temperature, is conducive to the insulation resistance improving bus.
It is identical with the overall dimension being connected row's square hole cross-over block that joint connects the square hole size that copper bar is opened, and after guaranteeing to connect copper installation, position is fixed.Connect row's square hole cross-over block and adopt double back character form structure, Outer Bottom Plating plays the effect be fixed on joint connection copper bar on the one hand, and its gauge can adjust according to bus bar copper row gauge on the other hand.The bore size of internal layer should be identical with the overall dimension of insulating sleeve, and the combination of double back shape structure and splice insulation plate guarantees that electric creepage distance meets national standard requirement.
Insulating sleeve arranges square hole cross-over block employing unsaturated polyester resin glass fiber enhancing film plastics press process with being connected, insulating sleeve square and circular configuration combination can guarantee joint is connected copper bar, splice insulation plate, punching bolt position fix, while guarantee again good insulation property and mechanical strength.
Joint steel clamp plate adopts 2.5 mm galvanized steel plain sheets to process, and leaves dish-shaped bullet pad crimping size and do not spray in the middle of outer plastic-blasting, guarantees that the electric property earth resistance continuity after bus duct connection complies with the national standard requirements.The medium design of joint steel clamp plate becomes four prominent column constructions and has the square hole with insulating sleeve same size, on four prominent column size and dish-shaped bullet pad pressing plate, four long lumbar holes is measure-alike, play the effect wearing and fix dish-shaped bullet pad, pressed joint connector, square hole plays the effect of fixed insulation sleeve pipe.
Dish bullet pad adopts the steel spring plate punching camber bullet pad that 5mm is thick, through Overheating Treatment, electrogalvanizing and hydrogen embrittlement process, makes it not only flexible but also can not occur cracking when bearing 300N.m.Guarantee that the connection copper bar of joint connector closely compresses with bus bar copper row to contact, reduce contact resistance heating.
Dish bullet pad pressing plate adopts iron plate copper facing chromium plating process after shaping that 8mm is thick, four protruded stigmas having four long lumbar holes and joint steel clamp plate are above measure-alike, can entangle fixing firmly, wherein the centre of a piece has the circular hole of 15mm, the silk tooth of M12 is attacked in the centre of another block, replaces nut to make punching bolted.Punching bolt plays the effect compressing busbar joint connector.
