Variable frequency transformer upper yoke assembly device used in high-low voltage electrical field

Abstract

The invention discloses a variable frequency transformer upper yoke assembly device used in the high and low voltage electrical field, the variable frequency transformer upper yoke assembly device comprises a transformer shell, a heat dissipation mechanism is arranged on one side of the transformer shell, an oil tank is arranged on the side, away from the heat dissipation mechanism, of the transformer shell, and coils are symmetrically arranged on the two sides of the bottom in the transformer shell; a heat dissipation mechanism is arranged between the two sides of the top of the coil, and transformer yokes are symmetrically arranged at the two ends of the heat dissipation mechanism; through the cooperation of a threaded rod, a mounting cylinder and hinge rods, when a rotating handle is rotated anticlockwise, the included angle between the two sets of hinge rods can be continuously reduced, then the two sets of transformer yokes are driven to get close to each other to clamp and fasten the transformer yokes, the difficulty of fastening the transformer yokes is reduced, and meanwhile, hole making work does not need to be carried out on the transformer yokes, so that loss is reduced, and the time needed for assembling the transformer yoke is shortened.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to iron yoke assembly equipment for variable frequency transformers used in the field of high and low voltage electrical fields. Background technique [0002] The iron core is the main magnetic circuit part of the transformer. The iron core and the coil wound on it form a complete electromagnetic induction system. The part of the iron core with the winding in it is called the "stem transformer core". Without the winding, it will only be magnetized. The part that acts on the road is called the "iron yoke. [0003] The iron yoke clamp in the transformer yoke is independent of other parts in the iron yoke structure. Generally, the iron yoke is fastened by passing the core screw through the iron yoke clamp and the iron yoke silicon steel sheet. Holes are opened on the silicon steel sheet of the yoke, and the insulation problem between the core-through screw, the silicon steel shee...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide the iron yoke assembly equipment for the frequency conversion transformer used in the field of high and low voltage electrical fields, to solve the problem that the iron yoke clips in the transformer iron yoke proposed in the background art are independent of other components in the iron yoke structure, and generally The iron yoke is fastened by the method of piercing the core screw through the iron yoke clamp and the iron yoke silicon steel sheet. The insulation problem between the clips makes it difficult to assemble; in order to prevent the subsequent loosening of the transformer yoke during use, after the iron yoke is clamped and installed, it is necessary to use bolts to fix the clamping frame inside the transformer shell. Prevent the loosening of the transformer iron yoke that is subsequently clamped, resulting in damage to the transformer; since the clamping frame of the transformer iron yoke is mostly made of metal, and the volume is large, the clamping frame is placed and When inside the transformer, it is necessary to use a hanging device to put it into the inside of the transformer shell, and most of the hooks on the clamping frame are fixed and cannot be disassembled, so that the transformer will be affected to a certain extent during subsequent use. question
