Brief introduction to the products

S11型三相油浸密封式配電變壓器,具有節能環保、工藝先進、結構新穎、外形美觀等特點,可作為原“S9”型變壓器的更新換代產品,適用于10 kV級或20 kV級50Hz的配電系統。

S11 Three Phase Oil Immersed Sealed Distribution Transformer has the features of saving energy and protecting environment, advanced technology, novel structure, beautiful appearance and so on. It is the upgraded product as the original type “S9” transformer which is suitable for 10kV class or 20kV class 50Hz distribution system.

產品結構
Product Structure

鐵心:選用優質冷軋硅鋼片和多組全斜接縫步進搭接、綁扎結構,有效的改善了磁通密度在鐵心內部的分布狀況,滿足變壓器低損耗和低噪聲的節能環保要求。

繞組:選用優質無氧銅材/高強度漆包線(或紙包線)卷繞和多層圓筒式(或餅式/螺旋式)結構,安匝分布均勻,絕緣結構合理。高壓繞組和低壓繞組可采用聯體繞制,效率高,線圈緊實。并通過優化冷卻、散熱/溫升設計,對繞組線匝進行綁扎、夾緊和對繞組端部用層壓木壓實,以增強繞組機械強度和短路承受能力,確保變壓器安全可靠地運行。

器身:采用免吊芯和器身四周限位及吊板結構,有效地解決了器身懸空問題,器身不會位移,避免了運輸顛簸對產品質量的不利影響;器身所使用的緊固件均采用自鎖螺母,能保證長途運輸后不至于松脫。因此,新產品在投運前無需檢查。

油箱:選用波紋油箱或膨脹式散熱器油箱結構,免維修、無滲漏、體積小、散熱好、結構新穎,取消了儲油柜及吸濕器,油體積的變化依靠波紋油箱波紋片或膨脹式散熱器的彈性來補償、調節,隨著溫度升高/降低、變壓器絕緣油的增減而脹縮,同時使變壓器內部與空氣隔離,變壓器絕緣油不與氧氣和水份接觸,減緩絕緣油和紙等材料的老化速度,可延長產品使用壽命。并且油箱密封處采用耐油硅膠密封件,不易老化、開裂,使用多年無需更換。然而,新產品運行維護簡單,為用戶節省了停電維護的費用。

表面處理與涂層:零部件、油箱表面經磷化處理后用三防漆(防潮、防霉、防鹽霧)噴涂,可以滿足各種不同的使用環境,保證表面處理涂層不脫落、無銹蝕,色澤新鮮、光亮,外形美觀。


Iron core: it chooses the high-quality cold-rolled silicon steel sheets and multi groups entire ramp lap joints, banding structure. It effectively improved the distribution of the magnetic flux density within the iron core, and it met the requirements of low loss, low noise, energy saving and environmental protection of the transformer.

Winding: it chooses the high quality non-oxygen copper materials/ high strength enamelled wire (or paper-covered wire) winding and multilayer cylinder structure, even distributing ampere turns and reasonable insulation structure. High and low voltage windings can adopt the union winding, so the efficiency is high with the coil compaction. And by optimizing and cooling, heat dissipation/ temperature rise design, turn on the winding line for banding, clamping, and by the end of the winding wood laminate compaction, in order to enhance mechanical strength and short-circuit winding capacity, to ensure safe and reliable operation of the transformer.

Body: it adopts the structure of suspended core free and spacing around the body and hanging board, so that it solved the problem of body hanging in the air and the body can’t displace, at the same time, it avoided the bad impact to the product’s quality of the bumps on the transportation; The fastener using in the body adopts the locknut which can guarantee it wont get loose on the long distance transportation. Therefore, the new product is no need for inspection before putting into operation.

Tank: to choose the structure of corrugated tank or radiator expansion tank, maintenance-free, non-leaking, small size, good heat dissipation, novel structure, while canceling the oil storage tank and the moisture absorber, the changing of oil volume is regulating by the corrugated tank plates or the flexibility of radiator expansion tank. As the temperature is raised/ reduced, the increase or decrease in the transformer insulation oil is expansion or contraction, at the same time, it separates the transformer inside with the air, the transformer insulating oil does not touch with the oxygen and water, so that it will reduce the aging speed of insulating oil and paper materials to extend the using life of the product. Besides this, the seal of the tank adopts the oil proof silica gel seal parts, it is resistant to aging and crack, so that it can be used for many years without replacement. However, the operation and maintenance of the new product is simple, it is saving the cost of maintenance of power for the customers.

Surface treatment and coatings: the spare parts and tank surface are spray painting by three anti-paints (anti-damp, anti-rot, anti-salt fog) after phosphating, to meet a variety of use of the environment and to ensure that the coating surface treatment does not fall off, no rust, the color is fresh, bright, beautiful appearance.
