产品概述Characteristics

树脂绝 缘干式变压器安全,难燃防火,无污染,可直接 安装在负荷中心。免维护、安装简便,综合运行成本低、损耗低、防潮性能好,可在100% 湿度下正常运行,停运后 不经预干燥即可投入运行。局部放电量低、噪音小,散热能力强,强迫风冷条件下可以150% 额定负载运行。

配备有 完善的温度保护控制系统,为变压 器安全运行提供可靠保障,可靠性高。据对已经投入运行的10000 多台产品的运行研究,产品的 可靠性指标达到国际先进水平。

It is safe, non-pollute,and flame proof, which can be installed directly on the load center with the merits of free maintenance, easy installation, low combined operationcost, low loss and excellent humidity resistance. The transformer can be operated normally under 100% humidity and put into motion without dry in advance

when out of use It shares the properties of low partial electricity local discharge, low noise and large heat dispel capability, it can be operated with the rated load of 150% under the forced air cooling conditions. With perfect temperature protectcontrol system to ensure safty operation of the transformer Referring to the operation research

of10 thousand transformers have been putto use, their reliability norm have reached advanced international standard.


铁芯 Iron core

铁芯采 用优质取向冷轧硅钢片材料制造,45°全斜接缝结构,心柱采用绝缘带绑扎,铁芯表 面采用绝缘树脂漆密封以防潮防锈,夹件及 紧固件经表面处理以防止锈蚀。

此外,沪光还 开发了多阶步叠铁芯工艺,铁芯由 剪切线自动堆栈,铁芯成 型采用不叠上铁轭方案,有效地 降低了空载损耗、空载电流和铁芯噪音。

The iron core is made of high quality cold silicon steel sheet with 45 ℃ sloping seam, its barrel is strapped with insulated tape, and it is sealed with resin to be safeguarded against corruption and moisture, the clamping parts andfastener are corruption-proof followedby superficial treatment.

In addition, huguang have exploited multi-stepping laminated core technology, the core is self-stacked by shearing line, the iron molding adopts non-lamiated upper yoke to reduce the no-load loss, no-load current and iron noise.


低压箔式线圈Lv fooled winding

对于低电压、大电流线圈,其短路 时的短路应力较大,同时低压匝数较少,低压电 流越大采用线绕型式其安匝不平稳问题越突出,散热问 题也需着重考虑,此时低 压采用箔式绕组可较好解决上述问题,首先箔 式产品不存在轴向匝数和轴向绕制螺旋角,高低压绕组安匝平衡,短路时 变压器轴向应力较小,其次由于其绝缘较薄,工艺上 又可容易设置多层风道,散热问题也较好解决。我厂低 压箔式线圈在法国STOLLBERG 公司生 产的自动箔式绕线机上自动绕制,内部焊 接在绕线机上采用氩气保护焊接,精度高,焊接电阻小,无外部焊接过程。绕组层间采用DMD 绝缘,绕制完 毕后端部用树脂密封固化。

For LV and heavy current winding, its short-current stress is very large and low voltage turn is small at the same time, the heavierthe low voltage current is, the more prominent the problem of nonstabilityon ampere-turn which adopting wire-wound will be, and moreover, the heat dispersion should be considered, but the

above problem can be better solved by adopting foi l winding, at first, there has been no axial turns and axial winding helix angle for foil products, the ampereturn of high/low voltage winding is equal and the axial shortcurrent stress is small. Secondly, due to the laminated insulation, it is easy to set up multilevel air passage as

per its technology, so is the problem of heat diversion. Our foil winding auto wound on the auto foil winding machine, which supplied by France stollberg Corporation, adoptsprotective internal welding with argon, with the excellent properties of high accuracy, low welding resistance and non external welding process. The interlayer of

winding insulate DMD, the extreme end is sealed and solidified by resin.
