  • SC(B)型干式电力变压器

    SC(B)型干式变压器的绕阻由环氧树脂、玻璃纤维等材料在高真空下包封而成,是各类干式变压器中性能好的产品,特别适用于城市办公楼、城市电网、商务中心、居住小区、地下室、电站、工厂、医院、宾馆等各种场所。
    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.
  • 产品特点
    电气性能好,局部放电值低:
    干式变压器由于其独特的结构(高压绕组采用漆包扁铜线或铜带、低压绕组采用铜箔绕成)和其先进的制造工艺水平(高压绕组在真空中浇注环氧树脂并固化),使其局部放电值低。

    耐雷电冲击能力强:
    由于低压绕组采用铜箔绕成,层间电压低、电容大,箔式绕组起始电压分布接近线性,因此其抗雷电冲击能力强。

    抗短路能力强:
    由于高、低压绕组电抗高度相同,无螺旋角现象,线圈间的安匝平衡,高、低压绕组因短路引起的轴向力几乎为零,因此其抗短路能力强。

    抗龟裂性能好:
    干式变压器采用环氧树脂“薄绝缘技术”,满足了低温、高温及温度变化范围大的场合,满足了长期运行后的抗开裂要求,解决了“厚绝缘技术”难于解决的开裂问题,使干式变压器在技术上得到可靠的保障。

    过负载能力强:
    若相同容量的变压器负载损耗相等时,则铜箔的面积将比铜导体相应增大,体积增大后,填料树脂用量相应増多,因此绕组热容性大,变压器短时过载能力强。

    阻燃性能好:
    采用环氧树脂真空浇注工艺无环境污染,有利于环境保护,该变压器具有免维护、防潮、抗湿热、阻燃和自熄特性。
    损耗低、噪声低:铁芯通常采用矿物氧化物绝缘的优质冷轧硅钢片,通过先进的加工工艺,使损耗水平和空载电流降至低,并取得非常低的噪声水平,同时装配好的铁芯,在其表面封涂三防绝缘漆,以防尘、防腐、防烟雾和锈蚀。

    耐温等级高:
    环氧树脂干式变压器属于F级或H级绝缘,长期可在155℃或180℃高温下安全运行。在相同容量下,它的体积小、重量轻,可节约安装费用等。

    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.
