产品特点 Characteristics of the product 温控、温显 Temperature control and temperature display
我厂生产的 10kV 级 SC(B)10、SC(B)11、SC(B)12、SC(B)13 型电力变压 温控系统由温度控制器和安装在产品最热点即低压绕组上端部的 PTC 测温
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 元件构成，实现对变压器的温度测量与控制，若由于过载运行或故障引起
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， 变压器绕组温度过高，温度控制器发出报警信号，温度超过安全值时会自
使产品具有如下特点： 行跳闸。采用强迫风冷时则由温度控制器根据绕组温度高低决定冷却风机
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， 的投入或切换。
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， 温显系统直接显示变压器运行过程中绕组的热点温度，可和温控系统配合
机械强度高，局部放电小，可靠性高。 使用。
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， 温控和温显系统可以安装在距变压器主体一定距离外，其测温元件引线的
不会因短路产生电弧，高热下树脂不会产生有毒有害气体。 长度分别为：
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 温控：<20m/ 温显：<10m（二线制）/<100m( 带有补偿导线的二线制 )
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 Temperature control system is composed of temperature controller
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)。 and PTC thermometer element of lower voltage winding in the

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 Direct indication of temperature display system during the operation
降低线路造价和节省昂贵的低压设施费用。 of the transformer winding hot spot temperature,and temperature
control system can be used in conjunction.
The 10kV SC(B)10, SC(B)11, SC(B)12 and SC(B)13 power transformers Temperature control and temperature display system can be
produced by our factory are dry type transformers with low-noise
and low-loss resin wound coil with product type certificate. Due installed in a certain distance away from the main transformer, the
to advanced design, high quality materials, scientific formulation, length of temperature component is:
strict process and high standard of testing, the products have the Temperature control: <20m/Temperature display: <10m (2 wires)
following characteristics:
1. The high voltage winding of copper wire, low voltage winding <100m (two wires with a compensating conductor)
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.
