Description
Technical field
The utility model relates to stretching structure between a kind of transformer pressing plate and iron core upper yoke.
Background technology
In electric power system, transformer is as one of crucial power equipment, and its anti-short circuit capability is one of its most important performance requirement.Stretching between iron core and device body is the most important thing especially.Between traditional transformer core upper yoke, stretching structure is put into backing plate between iron core upper yoke and pressing plate after need to device body integral body being forced down with hydraulic press, easily causes pressing plate distortion and complex operation.
Utility model content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, stretching structure between a kind of transformer pressing plate and iron core upper yoke is provided, solve stretching structure between traditional transformer core upper yoke and after need to device body integral body being forced down with hydraulic press, backing plate is put between iron core upper yoke and pressing plate, easily cause the problem of pressing plate distortion and complex operation.
The utility model solves the technical scheme that its technical problem adopts: stretching structure between a kind of transformer pressing plate and iron core upper yoke, comprise iron core upper yoke, iron core upper yoke below is provided with pressing plate, between iron core upper yoke and pressing plate, be provided with for by the backing plate of stretching between iron core upper yoke and pressing plate, backing plate upper surface be fixedly connected with for the protection of iron core upper yoke surface not with the rigid U-shaped cardboard contacting of backing plate, backing plate one end side surface is slope, the gap that backing plate inserts between iron core upper yoke and pressing plate by slope horizontal direction is connected with pressing plate with iron core upper yoke, between backing plate and pressing plate, by bakelite bolt, be fixedly connected with.
Further, for convenient, insert, when backing plate inserts the gap between iron core upper yoke and pressing plate, slope upward.
Further, in order to promote protectiveness, between U-shaped cardboard and backing plate, be provided with bradyseism shoe.
Further, in order to promote fail safe, iron core upper yoke lower surface is fixedly connected with wear-resistant protective layer.
The beneficial effects of the utility model are, between a kind of transformer pressing plate of the present utility model and iron core upper yoke, stretching structure is inserted the gap between iron core upper yoke and pressing plate by having the backing plate level of U-shaped cardboard, the distortion of cancelled that the use of hydraulic press reduces artificial the pressing plate avoided, also can meet the function of stretching between iron core upper yoke and device body pressing plate simultaneously, can fixedly prevent horizontal displacement with pressing plate again, this apparatus structure is simple, easy to operate, not fragile, cost is low, is a kind of axial tightening device that can meet transformer short-circuit performance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is U-shaped cardboard and backing plate scheme of installation
In figure 1, iron core upper yoke; 2, U-shaped cardboard; 3, bakelite bolt; 4, backing plate.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
Stretching structure between a kind of transformer pressing plate as depicted in figs. 1 and 2 and iron core upper yoke, comprise iron core upper yoke 1, iron core upper yoke 1 below is provided with pressing plate, between iron core upper yoke 1 and pressing plate, be provided with for by the backing plate 4 of stretching between iron core upper yoke 1 and pressing plate, backing plate 4 upper surfaces be fixedly connected with for the protection of iron core upper yoke 1 surface not with the rigid U-shaped cardboard 2 contacting of backing plate 4, backing plate 4 one end side surface are slope, the gap that backing plate 4 inserts between iron core upper yoke 1 and pressing plate by slope horizontal direction is connected with pressing plate with iron core upper yoke 1, between backing plate 4 and pressing plate, by bakelite bolt 3, be fixedly connected with.
Further; for convenient, insert, during gap that backing plate 4 inserts between iron core upper yokes 1 and pressing plate slope upward, further; in order to promote protectiveness; between U-shaped cardboard 2 and backing plate 4, be provided with bradyseism shoe, further, in order to promote fail safe; iron core upper yoke 1 lower surface is fixedly connected with wear-resistant protective layer; backing plate 4 horizontal directions are knocked in the gap between iron core upper yoke 1 and pressing plate, and backing plate 4 one end have slope, thereby conveniently knock in gap.In order to damage iron core in the process that prevents from knocking in, U-shaped cardboard 2 avoids direct rigid contact of backing plate 4 and iron core upper yoke 1 can be effectively by transformer stretching above when operation is put in backing plate 4, simple, facilitate, easy to operate.Between a kind of transformer pressing plate of the present utility model and iron core upper yoke, stretching structure is inserted the gap between iron core upper yoke 1 and pressing plate by having the backing plate level of U-shaped cardboard 2, the distortion of cancelled that the use of hydraulic press reduces artificial the pressing plate avoided, also can meet the function of stretching between iron core upper yoke and device body pressing plate simultaneously, can fixedly prevent horizontal displacement with pressing plate again, this apparatus structure is simple, easy to operate, not fragile, cost is low, is a kind of axial tightening device that can meet transformer short-circuit performance.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
