Description
Technical field
The utility model relates to a kind of 10kV bus bridge connector, belongs to bus installing area.
Background technology
In the electric substation of 110kV, total step-down transformer and bus bridge are rigidly connected.In order to save construction cost and the construction period of electric substation; the existing pedestal of total step-down transformer and the pedestal of bus bridge non-integral are built; due to; south is with the humid air and rainfall is large; the distribution of weak soil is comparatively extensive; therefore, the bus bridge be fixed on weak soil usually can be uneven sedimentation phenomenon.Be provided with bus bridge connector between total step-down transformer and bus bridge, existing bus bridge connector only considers the nargin of expanding with heat and contract with cold, and does not consider that the sedimentation of bus bridge will be provided as bus bridge connector and provide a pulling force.Bus bridge connector is connected by the bolt axially arranged with bus bridge, and after the long-term under tension effect of bus bridge connector, bolt will there will be inconsistent phenomenon, and after bolt dislocation, total step-down transformer, under the monitoring of self-protection program, can send trip command.
Summary of the invention
The utility model is the defect overcoming prior art, provides a kind of 10kV bus bridge connector, improves the stability of total step-down transformer operation, reliability and fail safe.
For solving the problem, the utility model provides following technical scheme: a kind of 10kV bus bridge connector, comprise the first conductive plate, second conductive plate, first pressing plate, second pressing plate and flexibly connect assembly, described first conductive plate is provided with first step, the described assembly one end that flexibly connects is fastened on described first step place by described first pressing plate, described second conductive plate is provided with second step, the described assembly other end that flexibly connects is fastened on described second step place by described second pressing plate, the described metallic conduction sheet flexibly connecting assembly and comprise some arranged stacked, described metallic conduction sheet is provided with fold.
The metallic conduction sheet flexibly connecting assembly and comprise some arranged stacked of the present utility model, multi-disc metallic conduction sheet can not only increase power delivery speed between the first conductive plate and the second conductive plate, and, multi-disc metallic conduction sheet can increase the bonding strength between the first conductive plate and the second conductive plate, avoid bus bridge to cause flexibly connecting assembly due to sedimentation to be pulled off, this structure effectively improves stability that total step-down transformer runs, reliability and fail safe.Metallic conduction sheet is provided with fold, the existence of fold effectively increases the relatively-movable distance between total step-down transformer and bus bridge, under the prerequisite that metallic conduction sheet hot strength is constant, the existence of fold effectively can improve the non-deformability of metallic conduction sheet, in other words, fold can make metallic conduction sheet when material is constant, increases the tensile strength flexibly connecting assembly, so that total step-down transformer is in the course of the work, more stable, the reliable and safety of operation.
Further, described fold comprises crest section and trough section, and the distance between described crest section and described trough section is 2mm-5mm.Existing metal guide electroplax width value is in the horizontal plane generally 10mm-20mm, metal guide electroplax length value is in the horizontal plane generally 18mm-30mm, the one-tenth-value thickness 1/10 of metal guide electroplax on vertical plane is 0.5mm-2mm, if the distance between crest section and trough section is less than 2mm, the metal guide electroplax of this structure is after under tension effect, distance between crest section and trough section can not change, in other words, bus bridge pedestal is after generation sedimentation, metal guide electroplax under tension can't be evened up, so, fold also just could not enough play increases relatively-movable distance value between total step-down transformer pedestal and bus bridge pedestal.South is windy, the particularly ground multiple stage wind such as Zhejiang, Fujian and Guangzhou, if the distance between crest section and trough section is greater than 5mm, under metal guide electroplax is subject to the effect of multiple directions wind-force, left and right upset, torsional deflection will be there is, thus cause metal guide electroplax by drawing crack, even fracture, because after metallic plate makes foil, the fragility value of metal guide electroplax will improve rapidly.Distance between crest section of the present utility model and trough section is 2mm-5mm, this distance be convenient to increase metal guide electroplax open and flat after length, meanwhile, weaken metal guide electroplax open and flat time the resistance of deformation that produces.
Further, described first step is provided with the first Metallic card raised up, one end of described metal guide electroplax is provided with the first breach coordinated with described first Metallic card, described second step is provided with the second Metallic card raised up, and the other end of described metal guide electroplax is provided with the second breach coordinated with described second Metallic card.Because south is windy, the particularly ground multiple stage wind such as Zhejiang, Fujian and Guangzhou, so, after wind speed acquires a certain degree, flexibly connect assembly and unordered swing can occur.First Metallic card can insert in the first breach, occur in the process of unordered swing flexibly connecting assembly, flexibly connect the assembly that flexibly connects that assembly is positioned at first step place not to be moved, this also just means, flexibly connecting assembly can not because of the unordered swing of self, and the phenomenon that generation is separated with the first conductive plate, this structure can effectively increase the bonding strength flexibly connecting assembly and the first conductive plate.Second Metallic card can insert in the second breach, and its syndeton is completely the same with the syndeton of the first Metallic card and the first breach, and the first Metallic card adds the bonding strength flexibly connecting assembly and the second conductive plate after inserting the second breach.
Further, described first pressing plate is provided with the first draw-in groove coordinated with described first Metallic card, and described second pressing plate is provided with the second draw-in groove coordinated with described second Metallic card.After metal guide electroplax and the first Metallic card clamping, metal guide electroplax double swerve can drive the first Metallic card double swerve, if the first Metallic card effect is rocked, the fit clearance between the first breach and the first Metallic card can be increased, the increase of fit clearance, metal guide electroplax scope of activities can be made to increase, and finally cause metal guide electroplax to be separated with the first conductive plate, so, first pressing plate is provided with the first draw-in groove, is added the non-deformability of the first Metallic card by the first draw-in groove.In like manner, the second draw-in groove adds the non-deformability of the second Metallic card.
Further, described 10kV bus bridge connector also comprises the first securing member and the second securing member, described first securing member is threaded with described first conductive plate axially across after described first pressing plate and described metallic conduction sheet, and described second securing member is threaded with described second conductive plate axially across after described second pressing plate and described metal guide electroplax.
Further, adjacent described metallic conduction sheet is mutually concordant.Adjacent metal conducting strip is under concordant state, the moveable scope of metallic conduction sheet diminishes, and the identical adjacent metal conducting strip of shape easily fits together, after adjacent metal conducting strip fits together, active force required for the deformation of metallic conduction sheet will become large, and this structure can effectively increase the non-deformability flexibly connecting assembly.
