Abstract
The invention relates to a single insert sheet type bus duct conductor joint. The bus duct joint comprises a joint conductor current-carrying compensation connecting sheet (2) and an insulation board (1), wherein the joint conductor current-carrying compensation connecting sheet (2) is clung to one surface of the insulation board (1), a step-shaped transition conductive block (21) is arranged in the middle of the joint conductor current-carrying compensation connecting sheet (2), one or more ladder-shaped insulation bolt connecting hole (22) is/are formed in the middle of the step-shaped transition conductive block (21), and an insulation sleeve (3) is nested at the inner side of the ladder-shaped insulation bolt connecting hole (22). The single insert sheet type bus duct conductor joint not only efficiently compensates a conductor section occupied by the insulation bolt connecting hole in a limited space, but also meets the requirement on electric clearance and creepage distance, reduces the material consumption of the insulation board to the maximum extent, lowers the cost, is safe and reliable for joint contact, high in thermal conduction efficiency, and the joint achieves the effects of being low in temperature rise, safe and reliable in properties, simple in structure and convenient and fast to install and saving materials and energy.
Description
Technical field
The present invention relates to the technical field of the insulation of bus duct joint two-phase and conductor connection, belong to the one list blade inserting bus duct conductor tab in busbar joint system.
Background technology
Current bus duct joint be connected with employing plug-in type, also have and adopt dock splicer system.
The major drawbacks of plug-in type installs inconvenience, quality of fit is poor, insulated bolt connecting hole takies the space of conductor, as low capacity bus plug plugging position, to there will be cross-sectional area of conductor inadequate, the overall cross section strengthening bus-bars conductor can only be relied on to carry out the cross section deficiency of supplementary joint local, cause small-volume bus duct cost to remain high.
Dock splicer compensates insulated bolt hole to the loss of cross-sectional area of conductor with two-sided conductor tab, the splicer insulation assembly that the method adopts is too complicated, its drawback is, insulation assembly adopts moulded plastic manufacture, description is many, complex structure, and the accuracy of manufacture requires high, die cost is high, makes whole splicer high expensive.After splicer intermediate insulation bolt-locking, existence is middle tightly, both sides are loose, and discontinuity, conductor contact face contacts unreal phenomenon.And moulded plastic is in order to proof strength, general thickness is thicker, and heat conduction efficiency is low, is unfavorable for that joint dispels the heat, and use in running, joint superheating phenomenon is serious.
Summary of the invention
technical problem:object of the present invention is intended to overcome the drawback that the insulation of existing dock busbar joint two-phase and conductor connect structure exist, provide that a kind of insulation board is thin, heat conduction efficiency is high, temperature rise is low, performance safety is reliable, simple structure, saving manufacturing cost, installation single blade inserting bus duct conductor tab easily.
technical scheme:single blade inserting bus duct conductor tab of the present invention comprises a strip terminal conductor current-carrying and compensates brace and a slice insulation board, joint conductor current-carrying compensates the one side that brace is attached to insulation board, overlap mutually with the single-phase conductor of bus duct, compensate the middle part of brace at joint current-carrying and be provided with a step-like transition conducting block, be provided with one or more stair-stepping insulated bolt connecting hole at the middle part of transition conducting block, survey in stair-stepping insulated bolt connecting hole and stud with insulating case.
Described transition conducting block is a cuboid or square, compensates brace be connected as a single entity with conductor tab current-carrying.
beneficial effect:single blade inserting bus duct conductor tab of the present invention compensates transition conductor that brace and a slice insulation board be combined into and the two-phase inserted sheet that insulate by a strip terminal current-carrying insert between two-phase bus duct conductor owing to have employed, the not only cross-sectional area of conductor that takies of effectively compensating insulated bolt connecting hole in limited space, meet again the requirement of electric clearance and creepage distance simultaneously, decrease the material consumption of insulating barrier to greatest extent, reduce cost, junction contacts is safe and reliable, heat conduction efficiency is high, joint is made to reach temperature rise low, saving metal material and energy, performance safety is reliable, simple structure, effect is easily installed.
Accompanying drawing explanation
Fig. 1 is Facad structure schematic diagram of the present invention,
Fig. 2 is the cross-sectional view of Fig. 1 centrally line.
Have in figure: insulation board 1, current-carrying compensate brace 2, transition conducting block 21, stair-stepping insulated bolt connecting hole 22, insulating case 3.
Embodiment
Technical problem to be solved by this invention how to insulate reliably in guarantee, to guarantee on the basis of electric clearance and creepage distance, reduce the thickness of insulation board, improve heat conduction efficiency, make full use of limited space simultaneously and take to compensate insulated bolt the electric conductor cross section that bus duct joint link position loses, accomplish safe and reliable.
The method of attachment that bus duct conductor tab bonding conductor of the present invention adopts is dock, single blade inserting bus duct conductor tab of the present invention comprises a strip terminal current-carrying and compensates brace 2 and a slice insulation board 1, joint current-carrying compensates the one side that brace 2 is attached to insulation board 1, overlap mutually with the single-phase conductor of bus duct, compensate the middle part of brace 2 at joint current-carrying and be provided with a step-like transition conducting block 21, be provided with stair-stepping insulated bolt connecting hole 22 at the middle part of transition conducting block 21, survey in stair-stepping insulated bolt connecting hole 22 and stud with insulating case 3; Described transition conducting block 21 is a cuboid or square, compensates brace 2 be connected as a single entity with joint current-carrying.
For meeting electric clearance and creepage distance technical requirement, connecting hole is designed to shoulder hole.Stud with insulating case on the two sides of insulating barrier connecting hole, insulating case is through the shoulder hole of brace.
