Abstract
The utility model discloses a clamping piece for a three-dimensional rolled-iron-core variable-frequency speed-regulation dry-type rectifier transformer, belonging to the technical field of power equipment. The clamping piece comprises an upper clamping piece (1) and a lower clamping piece (2), each of which is welded by square steel and is approximately of a regular triangle-shaped frame. The upper clamping piece (1) is connected with the lower clamping piece (2) through at least four fastening screws (7), wherein at least one fastening screw (7) is connected with the middle parts of the upper clamping piece (1) and the lower clamping piece (2). The clamping piece can effectively support and prevent an iron core from being stressed by external force, can evenly fasten coils and can be used as the skeleton of the entire transformer to support parts such as lead wires, a nameplate and temperature controllers. The clamping piece has the advantages that the good electromagnetic performance of the annealed rolled iron core can be prevented from being damaged, the capability of resisting axial electrodynamic force when short circuits suddenly occur in the transformer can be improved, and the no-load loss and the noise can be reduced.
Description
Technical field
The utility model belongs to the technical field of power equipment, specifically is meant a kind of three-dimensional volume iron core frequency control dry rectifier transformer folder that is used for.
Background technology
In the market the solid that dry-type transformer adopted volume iron core, the three-phase magnetic circuit of iron core is symmetry fully, and magnetic resistance is little, and exciting curent, no-load loss are low.But in the assembling of transformer and running as can not effectively protect, the performance of iron core is affected, causes its no-load loss and noise to increase iron core.Traditional plane formula iron core folder can not play effective supporting and protective effect.
The utility model content
The purpose of this utility model is to provide a kind of and can be effectively solid volume iron core is played supporting and protective effect, conveniently compresses the solid volume iron core frequency control dry rectifier transformer folder of coil simultaneously.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: three-dimensional volume iron core frequency control dry rectifier transformer folder, comprise the upper clamping piece that is roughly the equilateral triangle framework and the lower clamping piece that are welded into by square steel, described upper clamping piece is connected by at least four clamping screws with lower clamping piece, wherein has at least a clamping screw to be connected the middle part of upper clamping piece and lower clamping piece.
Described upper clamping piece is provided with each limit triangle pressing plate parallel with the leg of frame relatively with lower clamping piece inside, the relative Zhi Tie that is provided with in the outside of upper clamping piece and lower clamping piece, but be equipped with the hole that the tight screw rod of voltage supply passes on pressing plate and the Zhi Tie.
Described upper clamping piece top is provided with boatswain chair, and described lower clamping piece bottom is provided with base.
Described upper clamping piece is provided with installing rack, and described lower clamping piece is provided with installing rack.
Because upper and lower folder all adopts square steel to be welded into tower structure, this framework partly surrounds a bearer bar at the iron yoke of three-phase stereo volume iron core.By clamping screw upper and lower folder is connected into a rigid frame during assembling, and turn clamp nut, make each limit of upper and lower folder, three angles of triangle pressing plate evenly compress the upper/lower terminal of coil.
The utility model supporting and protecting iron core effectively makes it not be subjected to external force, also can evenly compress coil, and as the skeleton of whole transformer, parts such as supporting lead-in wire and nameplate, thermostat.Good electromagnetic performance was not destroyed after the utility model guaranteed the volume core annealing, and anti-axial electrodynamic ability has reduced no-load loss and noise when having improved the transformer sudden short circuit.The utility model is specially adapted to three-dimensional volume iron core, and compact conformation is simple, convenient and practical, cost is low, consumption reduction, noise reduction are remarkable.
