Abstract
The utility model discloses a clamping piece for a three-dimensional wound core dry transformer, which belongs to the technical field of an electric device. The clamping piece for the three-dimensional wound core dry transformer comprises an upper clamping piece (1) and a lower clamping piece (2) which are welded by steels and are generally triangular frames, wherein the upper clamping piece and the lower clamping piece are connected with each other through at least three compression screws; insides of the upper clamping piece and the lower clamping piece are correspondingly provided with triangular positioning racks (4) various edges of which are parallel to edges of the frames; and outsides of the edges of the frames of the upper clamping piece and the lower clamping piece are correspondingly provided with pressure plates (5). The clamping piece for the three-dimensional wound core dry transformer can effectively bear and support a magnet core so as to make the magnet core not influenced by an external force, can also uniformly press a coil, and is taken as a framework of the whole transformer to bear components such as leading wires, name plates, thermostats and so on. Moreover, the clamping piece for the three-dimensional wound core dry transformer guarantees that good electromagnetic performance is not damaged after the wound core is annealed, improves the ability of the transformer in resisting axial electromotive power under the condition of emergent short circuit, reduces the open circuit losses, effectively inhibits vibration of the noise in the clamping piece, and makes the noise of the transformer maintain an ideal level.
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, and can not suppress noise and vibrate in folder.
The utility model content
The purpose of this utility model be to provide a kind of can be effectively to three dimensional wound core rise supporting and protective effect, simultaneously conveniently compress coil, reduce the three dimensional wound core dry-type transformer folder of noise.
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 triangular framing and the lower clamping piece that are welded into by steel, described upper clamping piece is connected by at least three clamping screws with lower clamping piece, described upper clamping piece is provided with each limit leg-of-mutton locating rack parallel with the leg of frame relatively with lower clamping piece inside, and the outside of the leg of frame of upper clamping piece and lower clamping piece is provided with pressing plate accordingly.
Owing to adopted above-mentioned structure; connect into a rigid frame by clamping screw when upper clamping piece described in the utility model and lower clamping piece assembling; this framework is the skeleton of whole transformer; space between the locating rack and the leg of frame surrounds a bearer bar; can roll up iron yoke part unshakable in one's determination by ccontaining three-phase stereo, pressing plate can compress three-phase stereo volume coil two ends of going up coiling unshakable in one's determination.
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, anti-axial electrodynamic ability when having improved the transformer sudden short circuit, reduced no-load loss, effectively suppressed the vibration of noise in folder, made noise of transformer remain on desirable level.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.
