Abstract
The present invention relates to a kind of for transformer core iron yoke clamping means, belong to technical field of transformer production.Technical scheme is: comprise clamped beam (1), lower clamped beam (2) and clamping screw (3), on four angles of upper clamped beam and lower clamped beam, all arrange the hole of coupling mutually, four clamping screws penetrate in the hole at four angles respectively, are fastened by bolts, form frame-type structure, the hole of upper clamped beam and lower clamped beam is slotted hole, for regulating the distance between clamping screw, and the end thread of clamping screw, for regulating the spacing of upper clamped beam and lower clamped beam, be applicable to the iron core of different-diameter.The present invention is coordinated by hydraulic jack, clamps yoke clip piece unshakable in one's determination, increases clamping force unshakable in one's determination, and when preventing iron core from rising, the relative folder displacement of lamination, reduces transformer noise and loss when iron core runs.Distance in folder can well be controlled, reduce the deflection of folder, increase clamping force unshakable in one's determination, increase work efficiency and alleviate manual operation burden.
Description
Technical field
The present invention relates to a kind of for transformer core iron yoke clamping means, belong to technical field of transformer production.
Background technology
In transformer production, transformer core clamping force in manufacturing process must ensure, as clamping force unshakable in one's determination is inadequate, easily causes the impact of the many-side such as core loss, noise, particularly important in high-power transformer.Certain clamping effect can be played by frock such as clamping clamp, clamped beam etc. after clamper for iron core standing, before standing up, put in place because bolt can not all tighten by manpower, and the reasons such as part core clamping distortion, can not ensure that clamping force unshakable in one's determination reaches right pressure.Often there are the quality problems such as seam is large, alter sheet, noise exceeds standard, zero load exceeds standard after clamper for iron core standing, have a strong impact on product quality and image, also increase after standing up simultaneously and repair time unshakable in one's determination and production cost.
Summary of the invention
The object of this invention is to provide a kind of for transformer core iron yoke clamping means, save time, laborsaving, ensure product quality simultaneously, control distance in folder, reduce the deflection of folder, increase clamping force unshakable in one's determination, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is: a kind of transformer core iron yoke that is used for clamps special tooling, comprise clamped beam, lower clamped beam and clamping screw, on four angles of upper clamped beam and lower clamped beam, the hole of coupling mutually is all set, four clamping screws penetrate in the hole at four angles respectively, be fastened by bolts, form frame-type structure, the hole of upper clamped beam and lower clamped beam is slotted hole, for regulating the distance between clamping screw, the end thread of clamping screw, for regulating the spacing of upper clamped beam and lower clamped beam, is applicable to the iron core of different-diameter.
A kind of for transformer core iron yoke clamping means, adopt above-mentioned special tooling, before clamper for iron core standing, be placed on lower yoke window place unshakable in one's determination, position is in center, window place; The spacing of clamped beam and lower clamped beam on special tooling is regulated according to thickness unshakable in one's determination; Hydraulic jack be arranged between core clamping and upper clamped beam, clamp core clamping by hydraulic jack, measure distance in core clamping in clamping process, interior distance stops clamping after reaching requirement; Fastening iron yoke tape and feet unshakable in one's determination, make iron yoke unshakable in one's determination clamp completely, and then by jack pressure release, remove special tooling, after completing, stand up iron core.
After upper clamped beam and lower clamped beam install, wide according to lamination, calculate required clamping force, then select the hydraulic jack of coupling, thus control iron yoke clamping force unshakable in one's determination.
Good effect of the present invention: coordinated by hydraulic jack, clamps yoke clip piece unshakable in one's determination, thus makes apart from reaching norminal size in folder, and increase clamping force unshakable in one's determination, when preventing iron core from rising, the relative folder displacement of lamination, reduces transformer noise and loss when iron core runs.Distance in folder can well be controlled, reduce the deflection of folder, increase clamping force unshakable in one's determination, increase work efficiency and alleviate manual operation burden.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention schematic diagram;
In figure: upper clamped beam 1, lower clamped beam 2, clamping screw 3, hydraulic jack 4, upper clamping piece unshakable in one's determination 5, lower clamping piece unshakable in one's determination 6, iron yoke tape 7, feet unshakable in one's determination 8, iron yoke 9 unshakable in one's determination.
