Abstract
The invention relates to a clamp, in particular to an angle-folded type clamp for three-dimensional iron cores, and belongs to the technical field of devices for electric power transmission and distribution. The angle-folded type clamp for the three-dimensional iron cores comprises six single V-shaped clamps which are formed by U-steel in a machined mode. An upper clamp is formed by three single clamps and a triangle through screws in a fixedly connected mode, and a lower lamp is formed by another three single clamps and a triangle through screws in a fixedly connected mode. Both the upper clamp and the lower clamp form a frame structure. The upper clamp and the lower clamp are connected through at least four tightly-pressing screws. At least one tight-pressing screw is connected in the middle of the upper clamp and the lower clamp. According to the angle-folded type clamp for the three-dimensional iron cores, a good electromagnetic property of an iron core is prevented from being damaged, capacity of resisting electrodynamic force when sudden short-circuit occurs is improved, and no-load loss and noise are reduced. The angle-folded type clamp for the three-dimensional iron cores is particularly suitable for the three-dimensional iron cores, simple in structure, convenient to use, practical, low in cost, capable of reducing loss and remarkable in effect of reducing noise.
Description
Technical field
The present invention relates to a kind of folder, be specifically related to a kind of fold angle type stereoscopic triangular iron core folder, belong to the power transmission and distribution equipment technical field, be suitable for transformer and reactor.
Background technology
The three dimensional wound core that present transformer adopts, three-phase magnetic circuit unshakable in one's determination is symmetrical, and magnetic resistance is little, and no-load current is low.But in the assembling of transformer and running as can not effectively protect iron core, performance unshakable in one's determination is affected, causes no-load loss and noise to increase.Traditional iron core folder can not play effective support and protective effect.
Summary of the invention
The object of the present invention is to provide and a kind ofly can be effectively stereoscopic triangular iron core is played support and protective effect, facilitates simultaneously the fold angle type stereoscopic triangular iron core folder of coil pressing.
Technical scheme
The technical solution adopted for the present invention to solve the technical problems is: fold angle type stereoscopic triangular iron core folder, comprise the single folder that is processed into six approximate " V " shapes by channel-section steel, three single folders are by screw rod and angle iron be composed of a fixed connection upper clamping piece and lower clamping piece, and upper clamping piece and lower clamping piece all form a tower structure.Described upper clamping piece is connected at least four clamping screws and connects with lower clamping piece, wherein have at least a clamping screw to be connected to the middle part of upper clamping piece and lower clamping piece.
Described upper clamping piece is provided with each limit subtriangular pressing plate parallel with folder relatively with lower clamping piece inside.The top of upper clamping piece has angle iron to be fixedly connected with, and having on angle iron can be for the hole of lifting, and the bottom of lower clamping piece also has angle iron to be fixedly connected with.Be equipped with on pressing plate and upper and lower folder and can supply to compress the hole that screw rod passes.
Because upper and lower folder is tower structure, this framework partly surrounds a bearer bar at the iron yoke of stereoscopic triangular iron core.By clamping screw, folder from top to bottom is connected into a rigid frame during assembling, and turn clamp nut, make each limit of upper and lower folder, the upper and lower end of three even coil pressings in angle of triangle pressing plate.
The present invention can effectively prop up the overfill protection iron core makes it not be subjected to external force, even coil pressing also, and as the skeleton of whole transformer, support the parts such as high and low pressure coil lead.The present invention guarantees that good electromagnetic performance unshakable in one's determination is not destroyed, and when having improved the anti-sudden short circuit of transformer, anti-axial electrodynamic ability, reduced no-load loss and noise.The present invention is specially adapted to stereoscopic triangular iron core, and is simple in structure, convenient and practical, cost is low, reduce the wastage, to reduce noise effects remarkable.
Description of drawings:
The present invention is further described below in conjunction with drawings and embodiments.
Fig. 1 is the schematic diagram of fold angle type stereoscopic triangular iron core folder of the present invention.
Fig. 2 is the upper clamping piece schematic diagram of fold angle type stereoscopic triangular iron core folder of the present invention.
Fig. 3 is the lower clamping piece schematic diagram of fold angle type stereoscopic triangular iron core folder of the present invention.
Embodiment
As shown in Figure 1, fold angle type stereoscopic triangular iron core folder of the present invention comprises upper clamping piece 1 and lower clamping piece 2.Upper and lower folder processes by channel-section steel, then is fixed together by angle iron 3 and 4 structure that forms a frame-type.Wherein upper clamping piece 1 is provided with support plate 5, is used for the fixedly lead-in wire of high and low pressure coil.There is circular hole at angle iron 3 middle parts that connect upper clamping piece 1, are used for lifting by crane whole transformer.Described upper clamping piece 1 is connected with lower clamping piece by 6 connections of at least four clamping screws, wherein has at least a clamping screw 6 to be connected to the middle part of upper clamping piece 1 and lower clamping piece 2.Described upper clamping piece 1 is provided with each limit subtriangular pressing plate 7 parallel with folder relatively with lower clamping piece 2 inside.Be equipped with the hole that can supply compression screw rod 6 to pass on pressing plate 7 and upper clamping piece 1 and lower clamping piece 2, turn the clamp nut that is screwed onto clamping screw 6 and can strain upper and lower folder.Transformer body is placed between upper clamping piece 1 and lower clamping piece 2 during assembling, turns clamp nut, until upper and lower folder coil pressing uniformly and effectively.
Claims (3)
