Description
Technical field
The present invention relates to a kind of transformer core clamp.
Background technology
At present, existing transformer core clamp adopts following assembling mode: iron core folder generally adopts metal material, with this, guarantees that iron core clamps, and reduces the noise that transformer operation produces, simultaneously for transformer body provides reliable stability skeleton.The use of metal material has strengthened the electric insulation distance of transformer, poor thereby transformer stability in use compares, and the use of metal clip increases eddy current consumption on the other hand, causes transformer operation self energy consuming ratio larger.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is that prior art scheme is improved and improved, and provides a kind of transformer core wooden folder, the object that reduce noise to reach, reduces energy consumption.For this reason, the present invention takes following technical scheme.
The wooden folder of a kind of transformer core, it is characterized in that: comprise polylith folder web, be located at the iron core stretching screw on folder web, be located at the curb girder connecting plate at folder web two ends, the both sides, front and back of iron core column upper end are respectively equipped with two blocks of parallel folder webs, the both sides, front and back of iron core column lower end are respectively equipped with two blocks of parallel folder webs, the two ends, left and right of folder web are respectively equipped with two and folder web curb girder connecting plate connected vertically, the folder web that is positioned at same one end is provided with a plurality of relative screw holes, iron core stretching screw is through the screw hole of front two folder webs, iron core column, after the screw hole of rear two folder webs, by fastening nuts, realize laterally fixing, the bottom of folder from top to bottom web is respectively equipped with horizontal pressing plate, supporting plate, described pressing plate, supporting plate are between folder from top to bottom web, described pressing plate, supporting plate are provided with a plurality of relative screw holes, described folder from top to bottom web is provided with a plurality of lock bridge bridges, the rear and front end of described lock bridge bridge matches with folder web respectively, and device body stretching screw is realized vertical fixing by fastening nuts after passing lower lock bridge bridge, supporting plate screw hole, pressing plate screw hole, the beam bridge of locking with strainer body.Folder web is connected with curb girder connecting plate is vertical, then by iron core stretching screw, connects, and stretching screw is uniformly distributed, and the power being simultaneously delivered on iron core is also uniformly distributed, and effectively iron core is played to clamping action; Between folder web and device body pressing plate, directly contact, cancelled the distance of original metal clip web and device body platen, effectively increased coil creep distance over the ground, thereby improved the stability of transformer; Due to, transformer core is skeleton function, transformer coil is directly embedded on iron core, during transformer operation, require coil vertical direction reliably to compress, by many device body stretching screws, the upper and lower wooden folder web of iron core is connected fasteningly, guarantee reliably the tensioning function of transformer coil vertical direction; The horizontal pull producing by iron core stretching screw and the vertical tightening force that device body stretching screw produces, make iron core become as a whole; Due to iron core folder material selection wood materials, thus when transformer moves, can not cause magnetic circuit deformity and change, so the eddy current loss that iron core folder produces will reduce greatly.Enforcement by above technical scheme can reach the object that clamps iron core, increases electric insulation distance and minimizing eddy current loss.
As the further of technique scheme improved and supplemented, the present invention also comprises following additional technical feature.
The top of described curb girder connecting plate is provided with four square grooves, and the groove width of curb girder connecting plate square groove is greater than folder web thickness and to embed folder web, realizes the location, front and back of folder web.
The bottom of folder web is provided with a plurality of square grooves, the groove width of folder web square groove is greater than curb girder connecting plate thickness, and mutually rabbet and makes the bottom surface of curb girder connecting plate equal with folder web bottom surface at the square groove place that establishes that establishes square groove place and folder web of curb girder connecting plate.Folder web and curb girder connecting plate mutually combine by square groove, simple in structure, in conjunction with firm.
The both sides, front and back of described lock bridge bridge are equipped with the position-limited edge bending inwards, two position-limited edges form the distance that width is more than or equal to adjacent folder web, two position-limited edges are matched with the phase back side that is positioned at two folder webs on Qie Tong one end, iron core column the same side respectively, and the bottom of lock bridge bridge and folder web top offset.Moving forward and backward of position-limited edge limitation lock beam bridge, makes position that lock bridge bridge wears screw rod all the time between two folder webs, during the tension of device body stretching screw, can not be shifted, and improves assembly quality and efficiency.
The bottom of described lock bridge bridge is provided with the limiting section of column, and the bottom surface of limiting section and pressing plate or supporting plate match.
Described limiting section is tubular, and square leg is established in its bottom, and leg middle part is offered for wearing the screw hole of device body stretching screw, and the height overall of limiting section and leg is less than or equal to the height of folder web.When assembling leg between two folder webs, the rotation of limitation lock beam bridge fore-and-aft direction guarantees the spacing of two folder webs to improve precision and the efficiency of assembling simultaneously.
Described pressing plate comprises front pressuring plate, rear fender, has the gap that is greater than 5mm between forward and backward pressing plate; Described supporting plate comprises front supporting plate, rear supporting plate, has the gap that is greater than 5mm between forward and backward supporting plate.Change pressing plate and supporting plate into left and right two halves, mainly improve the clamping action of the wooden folder web structure of iron core.
Described folder web, pressing plate, supporting plate and curb girder connecting plate are wooden insulating material, and device body stretching screw, lock bridge bridge and iron core stretching screw are metal material; Device body stretching screw, lock bridge bridge and iron core stretching screw are drawn ground connection by electric conductor.Metalwork is drawn ground connection by electric conductor, and the free charge that is suspended in the metal materials such as stretching screw and lock bridge bridge is all drawn to transformer, has guaranteed the reduction of eddy current loss.
Screw hole on folder web is mounting hole, and the size up and down of mounting hole is greater than side-to-side dimensions.Mounting hole the difficulty of processing that can reduce folder web, iron core is set, improve working (machining) efficiency, improve assembling speed simultaneously, improve the reliability clamping, reduce defect rate.
Beneficial effect: directly contact between folder web and device body pressing plate, cancelled the distance of original metal clip web and device body platen, effectively increased coil creep distance over the ground, thereby improved the stability of transformer; Due to iron core folder material selection wood materials, thus when transformer moves, can not cause magnetic circuit deformity and change, so the eddy current loss that iron core folder produces will reduce greatly.When the technical program guarantees to clamp iron core, increase the object of electric insulation distance and minimizing eddy current loss.
