Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, 2, 3, 4, 5, a kind of Assembling transformer core arm-tie assembly structure, comprise arm-tie upper end stiffener 1, arm-tie 3, arm-tie lower end stiffener 4, upper clamping piece and lower clamping piece, the magnet isolation tank of more than twice or twice is provided with in the middle part of arm-tie 3, arm-tie upper end stiffener 1 is fixed at arm-tie about 3 two ends respectively, upper clamping piece and arm-tie lower end stiffener 4, lower clamping piece, described upper clamping piece comprises upper clamping piece boatswain chair 7 and upper clamping piece web 9, upper clamping piece boatswain chair 7 is fixed on upper clamping piece web 9, described lower clamping piece comprises lower clamping piece hanging axis 5 and lower clamping piece web 6, lower clamping piece hanging axis 5 is fixed on lower clamping piece web 6.
In the present embodiment, ensure transformer coil nested surplus, arm-tie and upper clamping piece and lower clamping piece mechanical strength prerequisite under, consider that stray flux distribution and super, ultra high voltage large capacity field assembling transformer core and device body need repeatedly to disassemble, after handling and assembling, by weldering arm-tie upper end, the two ends of arm-tie 3 stiffener 1 and arm-tie lower end stiffener 4, and in the certain limit of middle part, open the magnet isolation tank of more than twice.Lower clamping piece hanging axis 5 and lower clamping piece web 6 weld rear formation upper clamping piece, insert in the location hole of arm-tie 3 lower end, install fastening with securing member 10 and arm-tie 3.In order to make arm-tie 3 and upper clamping piece web reliable contacts, upper clamping piece boatswain chair 7 and arm-tie upper end stiffener 1 are respectively equipped with the slope cooperatively interacted, upward, arm-tie 3 and upper clamping piece, and are installed fixing with securing member 10 down by the slope on arm-tie upper end stiffener 1 on slope on upper clamping piece boatswain chair 7.Because the lifting point of transformer core and device body is arranged on upper clamping piece web 9, in order to ensure the mechanical strength of arm-tie 3 and upper clamping piece, strengthen round steel 2 in the arm-tie upper end of the relevant position plug welding appropriate size of arm-tie 3 and upper clamping piece and upper clamping piece strengthens round steel 8, strengthen the welding bead intensity of arm-tie upper end stiffener 1 and upper clamping piece boatswain chair 7.
After arm-tie 3 and upper clamping piece have assembled, the clamping of core lamination stack and the hoisting function of device body can be realized, simplified the structure, facilitate the disassembling of Assembling transformer core, assembled, meet the requirement of Assembling transformer to greatest extent.
