Description
Technical field
The utility model relates to a kind of modular construction of power transformer parts, particularly relates to a kind of device body of 3-D triangle reel iron core transformer, is mainly used in the 3-D triangle power transformer.
Background technology
Power transformer is one of equipment the most key in a kind of electrical power trans mission/distribution system, the whole electrical power trans mission/distribution system of good and bad directly influence of power transformer.Because power transformer mainly is to be used for carrying out according to user's needs the conversion equipment of voltage, thus in service at transformer, can produce some losses.Because mostly present electrical transformer cores be the planar alignment laminated structure, the deficiency of this kind structure be that magnetic circuit is asymmetric, magnetic resistance is big, no-load current is big, no-load loss is high and during operation noise big.In order to reduce the loss of transformer, a kind of 3-D triangle reel iron core transformer has been proposed recently, this triangle reel iron core transformer is that the iron core with transformer changes the iron core that triangle is arranged into.Like Chinese patent 99114376.0 and 00220995.0 a kind of cubic three phase transformer iron core with round section and triangle iron core transformer have been proposed respectively; This kind iron core and transformer magnetic circuit are symmetrical, magnetic resistance is little, no-load current is little, no-load loss is low, the operation noise is low, and it has played a strong progradation to the development of transformer.But the iron core of triangle core iron core transformer has changed triangle into and has arranged, and this fabrication and processing for iron core has been brought disadvantageous place, and especially because of the design feature of 3-D triangle volume iron core, the device body of conventional transformer no longer adapts to.For embodying the saving space characteristic of volume iron core; And the particularity that adapts to its structure, generally all adopt square, circular device body contour now, but for the 3-D triangle transformer, exist material consumption high like this; Manufacture the high deficiency of cost, therefore necessary this is solved.Do not find to have the bibliographical information of this respect as yet through the Searches of Patent Literature.
The utility model content
The purpose of the utility model provides a kind of 3-D triangle transformer that is more suitable in order to overcome the deficiency of existing 3-D triangle oil tank of transformer, and material consumption is low, the uncomplicated again 3-D triangle reel iron core transformer of production technology device body.
The purpose of the utility model realizes through following technical proposals, a kind of 3-D triangle reel iron core transformer device body, and the device body contour of transformer is a triangle; Comprise three independently iron cores; Three iron cores are arranged according to isosceles triangle, and iron core is wrapped with high-voltage coil and low-voltage coil, and three iron cores are respectively equipped with upper frame and underframe up and down; Upper frame and underframe are the channel-section steel structure, and upper frame and underframe fasten as one three iron cores through bolt together; Between upper frame and iron core, be provided with the upper yoke that briquetting and backing plate constitute, upper frame compresses iron core through upper yoke; Between underframe and iron core, also be provided with lower yoke; In order to guarantee insulation, between upper yoke and iron core, be lined with the upper yoke insulation, between lower yoke and iron core, also be provided with the lower yoke insulation.Be respectively equipped with set square and following set square on upper frame and the underframe, last set square welds together with underframe and underframe respectively with following set square; Be provided with center bolt at last set square and following set square center, center bolt has the center bolt locating piece, and locating piece is the round steel structure, and it is more convenient that center bolt is installed.In order to dispel the heat, on upper yoke pad and last set square, open 3～6 circular holes, to strengthen heat radiation.
The beneficial effect of the utility model is: find through product trial-production; Former iron yoke cushion block and last set square are real plate structure, have stopped the part oil duct, and heat radiation causes certain influence to transformer; Through design improvement; Change underframe and underframe into the channel-section steel structure, on iron yoke cushion block and last set square, open 3～6 circular holes, to strengthen heat radiation.Former center bolt location is designed to rectangular configuration with locating piece, because of mismachining tolerance is bigger, between 2～3mm, center bolt is fixedly caused difficulty with the about error of design load, through design improvement, the rectangle locating piece is changed to the round steel structure, and it is more convenient that screw rod is installed.
