  • SC(B)型干式電力變壓器

    SC(B)型干式變壓器的繞阻由環氧樹脂、玻璃纖維等材料在高真空下包封而成,是各類干式變壓器中性能好的產品,特別適用于城市辦公樓、城市電網、商務中心、居住小區、地下室、電站、工廠、醫院、賓館等各種場所。
    Introduction
    The winding of SC dry-type power transformer is encapsulated by materials like epoxy resins, glass fiber, etc. under high vacuum. It has the best performance among various dry-type transformers, especially appropriate to be applied in office buildings, urban power grid, business centers, residential communities, basements, power stations, factories, hospitals and hotels, etc.
  • 產品特點
    電氣性能好,局部放電值低:
    干式變壓器由于其獨特的結構(高壓繞組采用漆包扁銅線或銅帶、低壓繞組采用銅箔繞成)和其先進的制造工藝水平(高壓繞組在真空中澆注環氧樹脂并固化),使其局部放電值低。

    耐雷電沖擊能力強:
    由于低壓繞組采用銅箔繞成,層間電壓低、電容大,箔式繞組起始電壓分布接近線性,因此其抗雷電沖擊能力強。

    抗短路能力強:
    由于高、低壓繞組電抗高度相同,無螺旋角現象,線圈間的安匝平衡,高、低壓繞組因短路引起的軸向力幾乎為零,因此其抗短路能力強。

    抗龜裂性能好:
    干式變壓器采用環氧樹脂“薄絕緣技術”,滿足了低溫、高溫及溫度變化范圍大的場合,滿足了長期運行后的抗開裂要求,解決了“厚絕緣技術”難于解決的開裂問題,使干式變壓器在技術上得到可靠的保障。

    過負載能力強:
    若相同容量的變壓器負載損耗相等時,則銅箔的面積將比銅導體相應增大,體積增大后,填料樹脂用量相應増多,因此繞組熱容性大,變壓器短時過載能力強。

    阻燃性能好:
    采用環氧樹脂真空澆注工藝無環境污染,有利于環境保護,該變壓器具有免維護、防潮、抗濕熱、阻燃和自熄特性。
    損耗低、噪聲低:鐵芯通常采用礦物氧化物絕緣的優質冷軋硅鋼片,通過先進的加工工藝,使損耗水平和空載電流降至低,并取得非常低的噪聲水平,同時裝配好的鐵芯,在其表面封涂三防絕緣漆,以防塵、防腐、防煙霧和銹蝕。

    耐溫等級高:
    環氧樹脂干式變壓器屬于F級或H級絕緣,長期可在155℃或180℃高溫下安全運行。在相同容量下,它的體積小、重量輕,可節約安裝費用等。

    Good electrical performance with low partial discharge value: 
    The high voltage winding of the dry-type transformer is winded with enamelled rectangular copper wires or copper strips and then cast with epoxy resins and solidified in high vacuum while low voltage winding is winded with copper foils. The unique structures and advanced manufacturing workmanship ensure a low value of partial discharge.

    Strong resistance to lightening shock: 
    Since low voltage winding is winded with copper foils, the foil winding has a strong resistance to lightening shock thanks to its low voltage between layers, high capacitance and an approximately linear distribution of initial voltage.

    Capability to withstand short circuit: 
    The reactance heights of low and high voltage windings are identical, as a result, no spiral angle phenomenon occurs and the ampere turns between the coils are in balance. As the axial forces of the windings caused by short circuit are almost zero, the capability to withstand short circuit of the product is excellent.

    Anti-cracking: 
    Epoxy resins are applied with thin-insulation technology in the dry-type transformer to fit for environments with low or high temperature and occasions with large temperature differences. The cracking problems after long-term operation, which remains unresolved through the thick-insulation technology, now have been solved. This is a guarantee of reliability for the technology of dry-type transformer.

    Strong overload capacity: 
    If transformers with the same capacitance have equal load loss, the area of copper foil will become larger than copper conductor. If the area expands, the amount of resins used will also increase, which leads to the increase of thermo capacity, and the overload capacity of the transformer in a short period is strong.

    Good performance of flame retarding:
     Cast with epoxy resins in vacuum, the process of the product is environmentally friendly. And the product is provided with maintenance free, damp proofing, anti humidity and heat, flame retarding and self-extinguishing features.

    Low loss and noise: 
    Made of cold rolled silicon steel sheet insulated with mineral oxide, the iron core is processed with advanced workmanship to minimize the loss level and no-load current and to lower the noise. The surface of the assembled iron core is coated with protective insulating paint to protect the iron core from dust, corrosion, smog and rust.

    High level of temperature durance: 
    The insulation level of epoxy resins dry-type transformer is F or H, which means the product will work safely under 155℃ or 180℃ for a long time. It features a smaller volume and lighter weight comparing to products with the same capacity, which saves installation costs.
