            型號及含義

            Type and Meanings


            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,減緩絕緣油和絕緣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-group totally inclined joints stepping lapping and banding structure, which effectively improves the distribution of the magnetic flux density within the iron core and meets the requirements of energy saving and environmental protection such as low loss and low noise 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 (or cake-type / spiral type) structure with even distribution of ampere turns and reasonable insulation structure. High voltage winding and low voltage winding can adopt the conjoined winding, so the efficiency is high and the coil is tight and firm. Optimized cooling and heat dissipation/ temperature rise design are used to bind and clamp the winding line turn, and laminated wood is used at winding end to compact and tighten to enhance mechanical strength of the winding and short-circuit capacity to ensure the safe and reliable operation of the transformer.


            Body: It adopts the structure of hanging core free and spacing around the body and hanging board, which effectively solves the problem that the body is hanging in the air and that the body cannot displace to avoid the adverse effects on the quality of the products by the transportation; The fasteners used in the body adopt the self-locking nut which can guarantee that it will not loosen after long distance transportation; therefore, the new product is not required to inspect before putting into operation.


            Oil Tank: it selects the structure of corrugated oil tank or expansion radiator oil tank of maintenance-free,  no leaking, small size, good heat dissipation, novel structure, and removes the oil storage tank and the moisture absorber. The change of oil volume is compensated and regulated depending on the elasticity of corrugated films of the corrugated tank plates or the expansion radiator. As the rise / decrease of the temperature the transformer expands or shrinks depending on the increase or decrease of insulation oil; at the same time, the inside part of the transformer is separated with the air. The insulation oil of the transformer does not contact the oxygen and water to reduce the aging speed of insulation oil, insulation paper and other materials to extend the service life of the product. In addition, the seal of the oil tank adopts the oil resistant silica gel sealing part, which is not easy to age and crack nor requires to be replaced after use for many years. However, the operation and maintenance of the new product is simple, which saves the cost of maintenance during power failure for the users.


            Surface treatment and coatings: The spare parts and oil tank surface are sprayed with conformal coating (damp proof, rot resistance, anti-salt fog) after phosphating, which can meet different use environments and ensure that the surface treatment coating does not fall off nor corrode, with fresh and bright color and beautiful appearance.
