Abstract
The invention relates to a clamp, in particular to a three-dimensional triangle iron core clamp, and belongs to the technical field of electric power transmission and distribution devices. The three-dimensional triangle iron core clamp is characterized in that six single clamps are made of U-bars in a machined mode and in an approximate V shape, each three single clamps are fixedly connected through threaded rods and angle iron to form an upper clamp and a lower clamp, and the upper clamps and the lower clamps respectively form a frame type structure. The upper clamps and the lower clamps are connected through at least four pressing threaded rods, wherein at least one pressing threaded rod is connected in the middles of the upper clamps and the lower clamps. According to the three-dimensional triangle iron core clamp, the fact that a good electromagnetic property of an iron core is prevented from being broken is guaranteed, axial electrodynamic force resistant capacity of a transformer in a bursting short circuit is improved, and no-load loss and noise are reduced. The three-dimensional triangle iron core clamp is particularly applicable to the three-dimensional triangle iron core, simple in structure, convenient to use, practical, low in cost and remarkable in loss reducing effect and noise reducing effect.
Description
Technical field
The present invention relates to a kind of folder, be specifically related to a kind of 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 stereoscopic triangular iron core folder of coil pressing.
Technical scheme
The technical solution adopted for the present invention to solve the technical problems is: the 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.

The present invention is further described below in conjunction with drawings and embodiments.
Fig. 1 is the schematic diagram of stereoscopic triangular iron core folder of the present invention.
Fig. 2 is the upper clamping piece schematic diagram of stereoscopic triangular iron core folder of the present invention.
Fig. 3 is the lower clamping piece schematic diagram of stereoscopic triangular iron core folder of the present invention.
Embodiment
As shown in Figure 1, 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.
