Abstract
The utility model provides a single insertion-type busbar conductor joint. The busbar joint comprises a joint conductor current-carrying compensation connecting piece (2) and an insulating board (1). The joint conductor current-carrying compensation connecting piece (2) is attached to one side of the insulating plate (1). A step-shaped transition conductive block (21) is disposed at the central part of the joint current-carrying compensation connecting piece (2). The central part of the transition conductive block (21) is provided with one or more step-shaped insulating bolt connecting holes (22). An insulating sleeve (3) is inlaid at the inner sides of the step-shaped insulating bolt connecting holes (22). The single insertion-type busbar conductor joint of the utility model not only efficiently compensates the conductor cross section that is occupied by the insulating bolt connecting holes within a limited space, but also meets the requirements on electric clearance and creepage distance, minimizes the consumption of insulating barrier materials, reduces cost, makes joint contact safe and reliable, realizes high heat conduction efficiency, and achieves the effects of low temperature rise, material and energy saving, safe and reliable performance, simple structure and convenient installation.
Description
Technical field
The utility model relates to the technical field of the insulation of bus duct joint two-phase and conductor connection, belongs to a kind of single blade inserting bus duct conductor tab in the busbar joint system.
Background technology
At present bus duct joint be connected with the employing plug-in type, the dock of employing splicer system is also arranged.
The main drawback of plug-in type is that inconvenience is installed, quality of fit is poor, the insulated bolt connecting hole takies the space of conductor, it is inadequate cross-sectional area of conductor to occur such as low capacity bus plug plugging position, can only rely on the whole cross section of strengthening bus-bars conductor to replenish the cross section deficiency of joint part, cause the small-volume bus duct cost high.
The dock splicer is with the loss of two-sided conductor brace compensation insulated bolt hole to cross-sectional area of conductor, the splicer insulation assembly that the method adopts is too complicated, its drawback is, insulation assembly adopts the moulded plastic manufacturing, description is many, complex structure, and the accuracy of manufacture requires high, die cost is high, makes whole splicer high expensive.Existence is middle tightly behind the splicer intermediate insulation bolt-locking, both sides are loose, discontinuity, the phenomenon that the contact of conductor contact face is unreal.And moulded plastic is for proof strength, and general thickness is thicker, and heat conduction efficiency is low, is unfavorable for the joint heat radiation, uses in the running, and the joint superheating phenomenon is serious.
Summary of the invention
Technical problem:The purpose of this utility model is intended to overcome the drawback that existing dock busbar joint two-phase insulation and conductor connect structure exist, and provides 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 utility model comprises strip terminal conductor current-carrying compensation brace and a slice insulation board, joint conductor current-carrying compensation brace is attached to the one side of insulation board, overlap mutually with the single-phase conductor of bus duct, middle part at joint current-carrying compensation brace is provided with a step-like transition conducting block, be provided with one or more stair-stepping insulated bolt connecting holes at the middle part of transition conducting block, stud with insulating case in the interior survey of stair-stepping insulated bolt connecting hole.
Described transition conducting block is a cuboid or square, is connected as a single entity with conductor tab current-carrying compensation brace.
Beneficial effect:Single blade inserting bus duct conductor tab of the present utility model is owing to adopted the transition conductor and the two-phase insulation inserted sheet that are combined into by strip terminal current-carrying compensation brace and a slice insulation board to insert between the two-phase bus duct conductor, in limited space not only effectively compensating the cross-sectional area of conductor that takies of insulated bolt connecting hole, satisfied again simultaneously the requirement of electric clearance and creepage distance, reduced to greatest extent the material consumption of insulating barrier, reduced cost, the joint touch-safe is reliable, heat conduction efficiency is high, and it is low to make joint reach temperature rise, saving metal material and energy, performance safety is reliable, simple structure, easily effect is installed.
Description of drawings
Fig. 1 is Facad structure schematic diagram of the present utility model,
Fig. 2 is that Fig. 1 is along the cross-sectional view of center line.
Have among the figure: insulation board 1, current-carrying compensation brace 2, transition conducting block 21, stair-stepping insulated bolt connecting hole 22, insulating case 3.
Embodiment
Technical problem to be solved in the utility model is how to guarantee that insulation is reliable, to guarantee on the basis of electric clearance and creepage distance, reduce the thickness of insulation board, improve heat conduction efficiency, take full advantage of simultaneously limited space and compensate insulated bolt and take the electric conductor cross section that the bus duct joint link position loses, accomplish safe and reliable.
The method of attachment that bus duct conductor tab bonding conductor of the present utility model adopts is dock, single blade inserting bus duct conductor tab of the present utility model comprises strip terminal current-carrying compensation brace 2 and a slice insulation board 1, joint current-carrying compensation brace 2 is attached to the one side of insulation board 1, overlap mutually with the single-phase conductor of bus duct, middle part at joint current-carrying compensation brace 2 is 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, stud with insulating case 3 in the interior survey of stair-stepping insulated bolt connecting hole 22; Described transition conducting block 21 is a cuboid or square, is connected as a single entity with joint current-carrying compensation brace 2.
For satisfying electric clearance and creepage distance specification requirement, connecting hole is designed to shoulder hole.Two sides at the insulating barrier connecting hole studs with insulating case, and insulating case passes the shoulder hole of brace.
