SC9系列树脂绝缘干式变压器

用途：

SC(ZB)9(QIH)系列干式变压器，系本公司从瑞士引进具有国际先进水平的树脂浇注薄绝缘干式电力变压器，被广泛用于高层建筑、商业中心、机场、车站、码头、地铁、工厂、地下配电站、海上石油钻井平台、发电厂等环境要求比较高的场所。

特点：

3.1 高压绕组采用漆包铜线，低压绕组用铜箔绕制。高压绕组用玻璃纤维网格布板。在真空状态下用进口环氧树脂浇注，固化后形成坚固的整体，机械强度高，局部放电量小，可靠性高。

3.2 阻燃、防爆、不污染环境、环保型，可安装在负荷中心。

3.3 线圈不吸潮。铁心、夹件经过特殊工艺处理可在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。

3 .4抗突发短路的能力强，而雷电和操作波冲击的水平高，产品过载的能力大。

3.5 线圈内外侧树脂绝缘层薄，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) 。

3.6 损耗低，节电效果好，运行经济，可免维护。

3.7 体积小、重量轻、占地空间小、安装方便。

3.8 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变压器的温度过高，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的投入或切换。

3.9 温度显示系统直接显示变压器运行过程中绕组的热点温度，可和温控系统配合使用。

Application

SC(ZB)9(QlH) series dry transformer is a kind of resin cast thin insulation dry transformer imported from Switzerland with international leading level, it is widely used in demanding places like high building, mall center, airport, bus station, wharf, subway, factory, underground power distribution plant, drilling platform of sea petroleum, power plant etc.

Character

1.Enameled copper wire is used for high voltage winding, while the low voltage winding is wound by copper foil. The high voltage winding uses fiberglass gridding cloth plate and uses imported epoxy resin for casting in vacuum condition, a firm integer forms after it is solidified, which owns high mechanical strength, small partial discharge and high reliability.

2.With flame resistance, explosion prevention, environmental pollution and environmental protection, it can be installed in load center.

3. The coil doesn't absorb moisture, the iron core and clamping piece can be operated in condition of 100% relative humidity and other severe environment after special process.

4. The products has strong ability to resist sudden short circuit, high protection against lightning and operating wave impulse, large overload capacity.

5. The resin insulation inside and outside of coil is thin with good thermolysis performance. It usually adopts natural air cooling (AN) system. Transformer of any protection class can be equipped with forced air cooling system (AF).

6. The products is of low loss, high energy saving efficiency, economical operation, maintenance free.

7. The products is of small volume, light weight, small space occupation, simple installation.

8. The temperature control system composes of temperature controller and PTC temperature measuring element installed in the hottest position, namely, upper end of low voltage winding, it realizes temperature measure and control for transformer. When the temperature is too high due to overload operation or fault, temperature controller will send out alarm signal, and it will trip itself when the temperature exceeds the safe value, The cut in/out operation of cooling fan is performed by temperature controller according to temperature of winding when forced air cooling is used. 9. The temperature display system directly displays hot point temperature of winding during transformer operation, and it could be used together with temperature control system.
