产品简介
Brief introduction to the products

SC(B)11型环氧 树脂浇注干式电力变压器其高/低压绕 组均采用环氧树脂绝缘浇注包封,选用环 氧树脂加玻璃纤维等绝缘材料,具有自熄特性,导热系 数和阻燃性能好。低压绕 组为双层圆筒式或铜箔绕制、高压绕 组采用分段圆筒式结构,较大容 量绕组在绕组中部设置冷却气道,以降低绕组温度,扩大散热面积。绕组经 脱气并在真空状态下浇注/干燥成型,固化后 形成坚固的圆筒形整体,绝缘性能有保证、安匝分布均匀、抗短路能力强、耐雷电冲击水平高。不会因短路产生电弧,且抗裂、耐高温,在高温 下树脂不会产生有毒有害气体,阻燃、防爆、不污染环境,可增强产品的机械/电气强度、延长产品的使用寿命。新产品 广泛应用于城乡电网建设与改造工程、高层建筑、商贸中心、宾馆酒店、居民小区、旅游景点、剧院、港口、机场、地铁、箱式变 电站等输配电系统。特别适 合于防火防爆要求高、负荷波动大以及污秽/潮湿等 比较恶劣或特殊的环境之中,可在100%湿度情 况下或在正常工作电压下长期安全可靠地运行,从而减 少了停电维修带来的损失和麻烦,新产品 弥补了油浸式配电变压器的缺陷。

SCB11 Epoxy Resin Pouring Dry Power Transformer, its high/low voltage winding both adopt the epoxy resin insulation pouring envelop, it has self-extinguishing feature, thermal conductivity and flame-retardant performance. The low voltage winding is double layers cylinder or copper foil winding, the high voltage winding is subsection cylinder structure. In order to reduce the temperature and enlarge the heat exchanging area, a greater capacity winding sets up the cooling airway in the center of it. Winding is molding by deaeration and pouring/drying under vacuum condition, after this step it became the firm cylinder, so that the insulation performance is guaranteed, ampere turns even distributing, strong anti-short-circuit capacity and high lighting-resistant level. It won’t bring the voltaic arc caused by short-circuit, crack and high temperature resistant. Under the high temperature the resin doesn’t produce the toxic and harmful gas, it’s anti-flaming, anti-explosive and nonpolluting, enhancing the mechanical/ electric strength and extending the using life of the products. The new product is widely used in urban and rural power grid construction and renovation project, high-rise buildings, commercial centers, hotels, residential areas, tourist attractions, theaters, ports, airports, subways, box-type transformer substation and other transmission and distribution system, especially suitable for use in high request of fire and explosion prevention, large load fluctuation, the dirty/ damp and bad or special environment. It can be operating safely and reliably under 100% humidity so that it reduces the losing and trouble of power cut maintenance. The new product also makes up for the defects of oil immersed distribution transformer.

The new product has advanced performance level, it chooses the type “11” technique data, comparing with GB/T10228-2008 standard, which reduced the no-load loss by 20% on average, the no-load current by 70% on average, the load loss by 10% on average and the noise class determination 10dB on average. It is accord with the national industrial policy and technology policy.

The new product is anti-flaming, anti-explosive and anti-corrosive, nonpolluting, it can be installed in the load center. The good humidity resistance makes it can be operating safely and reliably under 100% humidity. The strong load capacity forces the rated capacity to raise 20~40% when the wind is cooling.

High/low voltage winding epoxy resin vacuum pouring, crack resistant after the gelatin is solidified, high temperature resistance and strong mechanical strength. High/low voltage winding ampere turns even distributing, strong anti-short-circuit capacity and high lighting-resistant level.

The partial discharging capacity of new product≤10pC, good insulation performance and high electric strength extend the using life of the product.

The new product has the functions of automatic temperature monitoring and protection, according to  the requirements we can provide the different classes protective shells (IP20, IP30). It can prevent the happening of man-made accidents and it’s convenient to use inside.

The new product has small size , light weight, easy to install and maintenance free.
