Abstract
The utility model discloses a tridimensional wound core dry-type transformer clamp, belonging to the power equipment technical field. The tridimensional wound core dry-type transformer clamp comprisesan upper clamp (1) and a lower clamp (2), which are regular triangle frames in general and welded by square steel. The upper clamp (1) and the lower clamp (2) are connected with each other through atlease four compaction screws (7), wherein at lease one compaction screws (7) is connected at the middle of the upper clamp (1) and the lower clamp (2). The utility model can effectively support and protect a core not to be forced by the external force, the core also can hold down a coil uniformly, and is used as a frame of the whole transformer to support the parts such as a lead wire, a nameplate as well as a temperature controller and the like. The utility model ensures the good electromagnetic properties of the wound core after the wound core is annealed not to be damaged, improves the ability of anti axial direction electrodynamic force when the transformer occurs the short circuit suddenly, and decreases the no-load loss and noise.
Description
Technical field
The utility model belongs to the technical field of power equipment, specifically is meant a kind of folder that is used for the three dimensional wound core dry-type transformer.
Background technology
The three dimensional wound core that dry-type transformer adopted in the market, three-phase magnetic circuit unshakable in one's determination 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, performance unshakable in one's determination is affected, causes its no-load loss and noise to increase iron core.Traditional plane formula is unshakable in one's determination uses 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 three dimensional wound core is played supporting and protective effect, conveniently compresses the three dimensional wound core dry-type 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 wound core dry-type 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.
Because upper and lower folder all adopts square steel to be welded into tower structure, this framework partly surrounds a bearer bar at three-phase stereo volume iron yoke unshakable in one's determination.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.The utility model guarantees that the good electromagnetic performance in volume annealing unshakable in one's determination back is not destroyed, 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 wound core, and compact conformation is simple, convenient and practical, cost is low, consumption reduction, noise reduction are remarkable.
