Three Dimensional Wound Core Power Transformers

Yuebian Electric Co.,Ltd is one of the leading China three dimensional wound core power transformers manufacturers and suppliers, welcome to check three dimensional wound core power transformers price with us.Product FeaturesSaving energy, reducing noiseS13-M.RL of new energy-efficient three-dimensional triangularCompared to S7 transformers with the same capacity, 55% decline in no-load loss, load loss decreased 33%, no-load current by 85%, and the noise down 8dB(A)~13dB(A)Compared with the S9 transformers with same capacity, no-load loss dropped 50%, load loss decreased 80%, no-load current down more than 80% noise down 8dB(A)~11dB(A)In comparison with GB S11 same capacity transformers, no-load loss decreased by 25%, and load loss decreased 80%, no-load current drops more than 80%, noise down 8dB(A)~11dB(A)Compared to GB S13 laminated structure in the same capacity transformer, no-load current is decreased by 70%, and the noise down 5dB(A)~8dB(A)Two kinds of compatible voltageS11-M.RL-10-20, S13-M.RL-10-20 triangular wound core transformer has got voltage of 10kv and 20kv two kinds of compatible product lines. It is great convenience for the user when transition from 10kv to 20kv power grid.Three balanceThree-dimensional triangular wound core is composed of three identical single-frame mosaic three hearts column was an equilateral triangle arrangement, three column magnetic circuit length is exactly the same but the shortest and three hearts column loss is consistent, so three-phase is the balance.Stable quality, production efficiencyTriangular wound core three-dimensional volume is the core were carried out in the production line rolling same as the flat roll core, which is no need the cross-cutting device, eliminating quality fluctuations caused by artificial lamination, stacked, split iron yoke plug, 5-6 working procedure decreasing compared with stacked core transformer so its got high production efficiency, stable and reliable quality, and less affected by man-made factors.Ability to enhance the anti-short circuitThree-dimensional triangular wound core transformer device body structure determines its ability to withstand short circuit better than the flat type transformer. Reasons as follows:Frame parts and pads are located in the body of the surrounding medium voltage  platen pressed down with iron block, symmetrical three-phase forceCompared with flat-shaped layout of the coil. Coil pressure area is increased by 15.7%Folder items are classified as three-dimensional triangular frame structure welded into one. Due to the stability of three-dimensional triangle, the overall strength is strong, and three-phase force is the same.Anti-tamperDue to technical reasons and stacked core transformer is easy to theft. Apart the body of the fastene-will knock down transformer silicon steel sheet, and three winding and transformer silicon steel sheet separated mediately, silicon steel sheet coil and other valuable materials, can easily be to steal away.Because the wound core transformer core is a whole. Core knock to leave and not get down the coil. It is quite difficult to move out the whole core and , because a 100KVA transformer weight 400kg and 200kva transformer weight 650kg. It is not easy to separated the silicon steel, copper and other valuable objects. Therefore, the wound core transformer with a good anti-theft. Small location, good tooksWith compact structure, beautiful appearance, small location. Transformer tank structure is using similar triangles, so the volume is smaller than the conventional rectangular tank.Good economy, Cost-effectiveFor the same level performance laminated-type transformer, Three-dimensional triangular wound core transformer got loss values decrease and cost reductions. So you can reduce the investment cost for the user but also reduce annual operating costs.S11-M.RL series 10kv new energy-saving three-dimensional triangular wound core transformer.table{ border-collapse:collapse;} .table td, .table th{ border:1px solid #cdcdcd; padding:5px; word-break: break-all; word-wrap: break-word;}Capacity(kva)8010016020025031540050063080010001250160020002500Voltage combinationHV20±5%     20±2*2.5%LV0.4No-loss(W)18020028024040048057068081098011501360164022502400Load loss(W)12501500220026003050365043005100620075001030012000145001850024000No-loadcurrent(%)0.270.260.250.240.230.220.240.210.200.190.180.170.160.150.15Short-circuit impedance(%)444444444.54.54.54.54.54.55.5Body weight2782784395095916798189641128142416601802225531663158Oil weight(kg)15314916819722825230337541752664563078112391540Total weight(kg)5255547468569861124134016181939241939553135378456376089Dimension(mm)L111411481045109111141190122513941467157017311761174018361856B7229959058449651031106012071270136015101525151016991762H131413141376139413971422147715621594163616561768190814072088E1380380400400400550550550550550550550550660660InstallationDimensions(mm)E255055066066066082082082082082010701070107013001300D191919191919191919191919191919fig.122333344444444Low-voltage phase line terminal(mm)b383855555555808080100100120120155b12424303030304545455050606050d12.512.512.512.512.512.514.514.514.51818181819c6.56.56.59991515151818181815fig.22333344444444Low-voltage 0-line terminal(mm)b3838555555558080808080100100100b12424303030304545454545505050d12.512.512.512.512.512.514.514.514.514.514.5181818c6.56.56.59991515151515181818S11-M.RL series 20kv new energy-saving three-dimensional triangular wound core transformerS13-M.R Series 10KV new energy-saving three-dimensional triangular wound core transformer(High-quality sheet)Capacity(kva)160200250315400500630800100012501600Voltage combinationHV10±5%    10±2*2.5%LV0.4No-loss(W)2002402903404104805707008309701170Load loss(W)1850/17602185/20802560/24403065/29203615/34404330/4120496060008240960011600No-load current(%)0.190.180.170.160.160.150.150.140.130.120.11Short-circuit impedance(%)5.55.55.55.55.55.566666Body weight(kg)484556655756896104413521613170320652592Oil weight(kg)1852282632773234334144966566941045Total weight(kg)797937109612751306148313951503171717281880Dimension(mm)L10801109119612751306148313951503171717281880B935960103611041131128412101302148714971628H14111444145714671542159216491711172618361938InstallationDimensions(mm)E1400400400550550550550550550550550E2660660660820820820820820107010701070D1919191919191919191919Low-voltage phase line terminal(mm)fig.23333444444b3855555555808080100100120b12430303030454545505060d12.512.512.512.512.514.514.514.5181818c6.56.5999151515181818fig.23333444444Low-voltage 0-line terminal(mm)b38555555558080808080100b12430303030454545454550d12.512.512.512.512.514.514.514.514.514.518c6.56.5999151515151518Note: in table, above the "1" is for Dyn11 or Yzn11 connection, the bottom of the "1" is for Yyno connection.S13-M.RL Series 20KV new energy- saving three-dimensional triangular wound core transformer(High-quality sheet)Mostly energy-conservation distributing transformerAssessment on technology and economy of tridimensional toroidal-core, laminated iron core and amorphous distributing transformer(According to GB20052-2006 three-phase distribution transformer the allowable values of energy efficiency and evalucting values of energy)Conclusion: Upon the calculation above, the TOC value of the S13-M.RL is lowest, but the technical economy is better. Comparing with the S13-M.RL, the TOC value of the SH15-M and the S11 is higher by CNY30561 and CNY23168 respectively.
