Abstract
The utility model is a double-insertion-sheet bus duct conductor joint which comprises two joint current-carrying compensation connecting sheets (2) and an insulation board (1), wherein the joint current-carrying compensation connecting sheets (2) are symmetrically clung to two surfaces of the insulation board (1) respectively and are lapped with a bus duct single-phase conductor, the middle part of each joint current-carrying compensation connecting sheet (2) is provided with a step-shaped transition conductive block (21), a ladder-shaped insulation bolt connecting hole (22) is formed in the middle part of each step-shaped transition conductive block (21), and an insulation sleeve (3) is nested at the inner side of each ladder-shaped insulation bolt connecting hole (22). According to the utility model, as a transition conductor combined by the two joint current-carrying compensation connecting sheets and the insulation board is adopted and two-phase insulation sheets are inserted between two-phase bus duct conductors, a conductor section occupied by the insulation bolt connecting holes is efficiently compensated in a limited space, the requirements on electric clearance and creepage distance are met, and the material consumption of the insulation board is reduced to the maximum extent.
Description
Technical field
The utility model relates to the technical field of the insulation of bus duct joint two-phase and conductor connection, and the two-phase insulation and the conductor that belong in the bus duct joint system connect two inserted sheets.
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, be intended to overcome the drawback of existing dock busbar joint two-phase insulation and conductor connect structure existence, provide that a kind of insulation board is thin, heat conduction efficiency is high, temperature rise is low, performance safety is reliable, simple structure, alternative splicer insulation assembly, have the manufacturing cost of saving, easily a kind of pair of blade inserting bus duct conductor tab be installed.
Technical scheme: this pair blade inserting bus duct insulation of the present utility model and conductor tab comprise two strip terminal conductor current-carrying compensation brace and a slice insulation board, the two strip terminal conductor current-carrying compensation brace respectively symmetrical two sides that is attached to insulation board overlaps mutually with the single-phase conductor of bus duct, middle part at joint conductor current-carrying compensation brace is provided with a step-like transition conducting block, be provided with stair-stepping insulated bolt connecting hole at the middle part of transition conducting block, stud with insulating case in the inboard of stair-stepping insulated bolt connecting hole.
Described transition conducting block is a cuboid or square, is connected as a single entity with joint conductor current-carrying compensation brace.
Beneficial effect: the utility model is owing to adopted the transition conductor and the two-phase insulation inserted sheet that are combined into by two 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.

Fig. 1 is Facad structure schematic diagram of the present utility model,
Fig. 2 is the longitudinally cross-sectional view of center line of Fig. 1.
Fig. 3 is that Fig. 1 is along the cross-sectional view of cross central line.
Have among the figure: insulation board 1, current-carrying compensation brace 2, transition conducting block 21, 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 bus duct conductor tab 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, the insulation of this pair blade inserting bus duct and conductor tab comprise two strip terminal conductor current-carrying compensation brace 2 and a slice insulation board 1, the two strip terminal current-carrying compensation brace 2 respectively symmetrical two sides that is attached to insulation board 1 overlaps 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 inboard 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.
