10kV 级 SC(B)10、SC(B)11、SC(B)12、SC(B)13
环氧树脂浇注干式变压器 /Epoxy resin is poured into a dry transformer

产品特点 /Characteristics of the product
我厂生产的 10kV 级 SC(B)10、SC(B)11、SC(B)12、SC(B)13 型电力变压器为国内较早领有产品型号证书的低噪声低损耗型树脂绕注线圈干式变压器。由
于先进的设计、优质的材料、科学的配方、严格的工艺和高标准的检测，使产品具有如下特点：
1. 高压绕组用铜线，低压绕组用铜线或铜箔绕制，玻璃纤维毡填充包绕，真空状态下用不加填料的环氧树脂浇注，固化后形成坚固的圆筒形整体，机械
强度高，局部放电小，可靠性高。
2. 阻燃、防爆、不污染环境。缠绕线圈的玻璃纤维等绝缘材料具有自熄特性，不会因短路产生电弧，高热下树脂不会产生有毒有害气体。
3. 线圈不吸潮，铁芯夹件有特殊的防蚀保护层，可在 100% 相对湿度和其它恶劣环境中运行。间断运行无须去潮处理。
4. 抗短路、雷电冲击水平高
5. 线圈内外侧树脂层薄，散热性能好。冷却方式一般采用空气自然冷却 (AN)。对于任何防护等级的变压器，都可配置风冷系统 (AF)，以提高短时过载能力，
确保安全运行。
6. 损耗低，节电效果好，运行经济，可免维护。
7. 体积小，重量轻，占地空间少，安装费用低，不须考虑排油池、防火消防设施和备用电源等。
8. 因无火灾、爆炸之虞，可分散安装在负荷中心，充分靠近用电点，从而降低线路造价和节省昂贵的低压设施费用。

The 10kV SC(B)10, SC(B)11, SC(B)12 and SC(B)13 power transformers produced by our factory are dry type transformers with low-noise and low-loss resin
wound coil with product type certificate. Due to advanced design, high quality materials, scientific formulation, strict process and high standard of testing, the
products have the following characteristics:
1. The high voltage winding of copper wire, low voltage winding wound of copper wire or copper foil, glass fiber mat is filled with wrapping, vacuum packing
of the epoxy used without casting, curing to form a solid cylindrical overall, mechanical high strength, partial discharge of small, high reliability.
2. Antiflaming. anti-explosion will not pollute the environment. Glass fibre Coil winding coil such with self-extinguishing properties. and will not produce
electric arc for short-circuit, does not produce toxic or harmful gases in high temperature condition.
3. The coil does not absorb moisture, core clamps have a speaal corrosion protection layer, 100% relative humidity and other harsh environment. Interrupt
driving need not remove tide treatment.
4, short circuit resistant and high level oflightning impulse.
5, The resin inside and outside the coil is thin, heat dispersion is good. Cooling air is used air cool in nature (AN). For any degree of protection transformer,
equip with air-cooled system (AF), in order to improve overload capacity of short-term, and ensure safe operation.
6, lower consumption, energy-saving. Running for a savings, can be maintenance-free.
7, small volume, light weight, small area, lower installation costs, not need to consider oil tank, rire protection andbackup power, stand-by UPS.
8, Because there was no fire and explosion danger, installed in the load center can be distributed and fully close to the
power point, thus reduang the line low cost and save the expensive facilities costs.

外壳保护装置 /Shell protection device
外壳材料采用不锈钢或铝合金。防护等级达到 IP20 和 IP23。IP20 外壳可
防止直径大于 12mm 的固体异物进入，对变压器作进一步的安全保护。
IP23 外壳更兼具防止与垂直线 60°角以内的水滴流入，可适用于户外运行。
注：IP23 外壳会使变压器冷却能力下降，小容量的下降约 5%，大容量的
下降约 10%。
Shell is made of stainless steel or aluminum alloy. Protection grade can reach
IP20 and IP23. IP20 housing can prevent solid foreign objects of diameter
more than 12mm enter into and protect the transformer safely. IP23 housing
can prevent the vertical drop of less than 60 ° of flow, suits for outdoor
operation.
Note: lP23 housing can make the transformer cool, small capacity is
decreased by about 5%, high-capacity is decreasedby about 10%.
