Description
Technical field
The utility model relates to transformer mounting structure, is specifically related to a kind of syndeton of novel folder from top to bottom of three dimensional wound core transformer.
Background technology
For ensureing that the folder of three dimensional wound core transformer can clamp coil, the corresponding minor face place of upper and lower folder can be welded with the set square protruding folder if desired, drawing screw rod, rising and strengthening fastening effect for connecting.But current this structure has following shortcoming: 1), for considering electrical distance, the position of the set square of protrusion can make the outer deformation of device body large, thus causes fuel tank profile to increase, and become large, and steel plate materials consumption is large by oil mass; 2), transformer overall dimension is large, and floor space is large; 3), space availability ratio is low.In sum, the folder from top to bottom of three dimensional wound core transformer needs a kind of design completely newly.
Utility model content
To take up room large problem to solve existing three dimensional wound core apparatus for fixing transformer, the purpose of this utility model is the novel folder providing a kind of compact conformation for three dimensional wound core transformer, volume little.
The technical scheme that the utility model adopts is:
A kind of novel folder from top to bottom syndeton of three dimensional wound core transformer, comprise: upper clamping piece, lower clamping piece, draw screw rod and iron core, the described screw rod that draws is arranged in iron core, the inwall of described upper clamping piece surrounding edge is provided with set square, on lower clamping piece, corresponding set square is provided with fixed head, described upper clamping piece and lower clamping piece are separately positioned on two ends up and down unshakable in one's determination, described set square and fixed head respectively correspondence draw screw rod to offer through hole, and the through hole drawing screw rod to pass set square and fixed head is installed and passed through nut check.
As the further improvement of technique scheme, described iron core adopts three-phase symmetrical tridimensional structure, the three dimensional wound core be put together by three identical rectangle single frames.
As the further improvement of technique scheme, described in draw screw rod to be fixed on iron core column by binding strap, and to be distributed in outside three stem stems.Fixed by binding strap, make to draw screw rod not easily flexural deformation, can not swing, expediently lower clamping piece suit, and proof strength, improves stability, the expediently installation of lower clamping piece, location.
As the further improvement of technique scheme, described upper clamping piece is made up of three long limits and three minor faces, and three minor face inwalls of upper clamping piece are welded with a set square respectively.Further, described set square is a steel plate meeting requirement of strength, and offers circular hole in relevant position, is convenient to the installation of upper clamping piece, location; When set square is built-in, because folder is less to distance unshakable in one's determination, the length that set square stretches out does not need oversizely just can meet and draw screw rod to coordinate to install; In addition, the overhang of set square is little, and flexural strength is large, does not need to increase reinforcement bottom it; This structure had both saved the consumption of material, met requirement of strength again.
As the further improvement of technique scheme, on described lower clamping piece corresponding set square limit wall on offer threaded mounting hole, fixed head is bolted on the installing hole of lower clamping piece.Lower clamping piece is connected with the mode of fixed head with bolt, has both decreased welding job amount, has also facilitated installation.
As the further improvement of technique scheme, the position that described fixed head coordinates with lower clamping piece offers horizontal slotted hole, and fixed head offers longitudinal slotted hole with the position of drawing screw rod to coordinate.Such structure can improve installation effectiveness effectively, avoids the event that cannot install caused because of production error to occur, device body is assembled convenient.
The beneficial effects of the utility model are:
Folder of the present utility model is by built-in for the set square at minor face place, screw rod is drawn to be arranged in iron core, make machine body structure compact, volume is little, effectively can reduce the overall dimension of device body, thus reduces the overall dimension of transformer, and the effective use oil mass reducing fuel tank, save rolled steel dosage, improve the utilance in space, thus reduce the cost of product; This structure is convenient for assembly, effectively can improve the installation effectiveness of folder.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the schematic diagram of the novel folder from top to bottom syndeton of three dimensional wound core transformer;
Fig. 2 is the structural representation of set square;
Fig. 3 is the structural representation of lower clamping piece;
Fig. 4 is the structural representation of fixed head.
Drawing reference numeral illustrates: 1, set square; 2, upper clamping piece; 3, screw rod is drawn; 4, lower clamping piece; 5, fixed head; 6, binding strap; 7, unshakable in one's determination; 41, installing hole; 51, horizontal slotted hole; 52, longitudinal slotted hole.
Embodiment
Referring to figs. 1 through Fig. 4, the preferred embodiment that the utility model provides, a novel folder from top to bottom syndeton for three dimensional wound core transformer, comprises the upper clamping piece 2 and lower clamping piece 4 that are separately positioned on the upper and lower two ends of three dimensional wound core transformer, by drawing screw rod 3 to connect between upper clamping piece 2 and lower clamping piece 4.Upper clamping piece 2 is made up of three long limits and three minor faces, three minor face inwalls of upper clamping piece 2 are welded with a set square 1 respectively, set square 1 preferably meets the steel plate of requirement of strength, and offer through hole in relevant position, be convenient to the installation of upper clamping piece 2, location, because set square 1 overhang is little, flexural strength is large, do not need bottom it to increase reinforcement, both saved material, and met requirement of strength again.On lower clamping piece 4 corresponding set square 1 limit wall on offer installing hole 41, for mounting plate 5, fixed head 5 is bolted on the installing hole 41 of lower clamping piece 4, the position that fixed head 5 coordinates with lower clamping piece 4 offers horizontal slotted hole 51, and fixed head 5 and the position of drawing screw rod 3 to coordinate offer longitudinal slotted hole 52.Screw rod 3 is drawn to be arranged in core 7 unshakable in one's determination through the through hole of set square 1 and longitudinal slotted hole 52 of fixed head 5, and by binding strap 6 fixed iron core 7, draw screw rod 3 two ends to be provided with the screw thread of certain length, adopt nut screwing clamping, make upper clamping piece 2 and lower clamping piece 4 fastening, play the effect of clamping coil.
Novel folder of the present utility model is by built-in for the set square 1 at minor face place, screw rod 3 is drawn to be arranged in unshakable in one's determination 7, make machine body structure compact, volume is little, effectively can reduce the overall dimension of device body, thus reduces the overall dimension of transformer, and the effective use oil mass reducing fuel tank, save rolled steel dosage, improve the utilance in space, thus reduce the cost of product; This structure is convenient for assembly, effectively can improve the installation effectiveness of folder.
