11KV S13-M.RL 80~2500KVA 3 phase new energy saving three imensional triangular wound core transformer

Triangle structure three-dimenional wound ironcore power transformer

Three-dimensional triangular core power transformer Profile
> Power transformers,electricity-based products is extremely wide application. For decades, China and around the world have a long-term extension of Insert-type power transformers, its performance has not been fundamentally improved. The Golden Triangle company developed S13-M-RL, S11-M-RL series three-dimensional triangular core power transformer which is the core power transformer revolutionary generation,which is more reasonable,better performance, energy-saving and a new energy-efficient transformers.
> With the second urban and rural power grid construction and launched transformation of the power, how to improve the technological content of power transformer to better implement the national energy-saving and environmental protection policies, and actively promote energy saving, low consumption, environmental protection and application of new products has become an important issue. Three-dimensional core power transformer produced by Golden Triangle is a kind of traditional materials, but much quieter, reducing in the loss and saving materials in full compliance with international and domestic low-carbon economy and energy-saving emission reduction policies and guidelines . The product has been incorporated into the national energy efficiency power plant the first batch of selected energy-saving products; national resource conservation and environmental protection of the central budget investment projects; State Economic and Trade Commission, the original Guodian Company has issued a document to promote the energy-saving products; Shen power transformer will promote the iron triangle as a plug-piece core transformers, flat roll core power transformer as the replacement products.

Different sort of "core"
> Triangular core without cutting, and no punching, eliminating the traditional transformer horizontal, vertical joints, reducing the reluctance; cross section appear a circular,core fill factor is the largest,triangle three-dimensional structure to make it equal to three-phase magnetic circuit, and the shortest.Realizing the ideal transformer core structure.
> Triangular three-dimensional core is the continuous steel strip from the narrow to width, and then from wide to narrow. First winding three semi-circular cross-section inner core, then three-dimensional inner cores assembled together, and constitute the three a core pillar of the triangular cross-section similar to a circular three-dimensional core. Completely symmetrical three-phase equivalent magnetic circuit, shortening the iron yoke, the core columns fill factor high, its structure is recognized as the ideal structure of power transformers, which is flat roll core can not match, the tests showed a triangle of three-dimensional volume core power transformer is More than flat items of test data volume core power transformer, triangular three-dimensional core structure is a major breakthrough and leap for the power transformer core.Its birth known as "core power transformers revolution." Therefore, three-dimensional volume triangular core power transformer is a recognized as energy-saving, environmental protection, ultra-quiet green power transformer.

Feature
Saving energy, reducing noise
S13-M RL of new energy-efficient three-dimensional triangular
> Compared 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
Three balance
> Three-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 efficiency
> Triangular wound core three-dimensional volume is the core were carried out in the production line rolling same as the lat roll core , which is no need the cross-cutting device, eliminating quality luctuations caused by Artiicial lamination, stacked, split iron yoke plug,5-6 working procedure decreasing compared with stacked core transformer, so its got high production eficiency, stable and reliable quality, and less affected by man-made factors.

Ability to enhance the anti-short circuit
Three-dimensional triangular wound core transformer device body structure determines its ability to withstand short circuit better than the lat type transformer.Reasons as followes:
> Frame parts and pads are located in the body of the surrounding medium voltage platen pressed down with iron block, symmetrical three-phase force
> Compared 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, their overall strength is strong, and three-phase force is the same.

Anti-tamper
> Due to technical reasons and, Stacked core transformer is easy to theft. Apart the body of the fastener, will knock down transformer silicon steel sheet, and three winding and transformer silicon steel sheet separated immediately, 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 dificult to move out the whole core and coil, 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 looks
> Wi th compac t s t ruc ture, beautiful appearance, small location,Transformer tank structure is using similar triangles, so the volume is smaller than the conventional rectangular tank.

Good economy, Cost-effective
> For the same level performance laminated-type transformers, 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.

Actual case
> Case 1: For the new increasing capacity user
>According to the price of the material by May 2008, it need to use 65500 (yuan) for Purchasing S11-M transformer and need to use 73550 (yuan) for S13-M.RL transformers, using S13-M.RL-500/10 transformer need more to pay :73550-65500 = 8050 (yuan), but S13-M.RL-500/10 transformer to save annual operating costs than using S11-M.RL-500/10 (GB) transformer:27084-22746 = 4338 ( yuan). Therefore, only a year and 10 months, We can recover the investment by the savings in electricity costs.Thereafter, users can save 3794 (yuan) transformer operating costs.
> Case 2: For the replacement of the net operating transformer (S7) user
>S7-500 copper weight 260kg, core weight 654kg, steel weight 230kg, the oil weight 270kg, S7-500/10 transformer scrap can recover 18,215 yuan; In addition, if the original S7 transformers is not replaced, the average annual maintenance fee of about 1,000 yuan .
>One-t ime investment required to purchase S13-M.RL-500/10 transformer 73550-18215 = 55,335 yuan, S13-M RL, an annual saving of running costs and maintenance costs: 15072 +1000 = 16,072 yuan lower than the S7, only 3 years and 5 months that recover the initial investment costs, after that users can enjoy the significant economic benefits which S13-M.RL ultra-low-loss transformer produced (16,072 yuan per year).
