概述 / Product overview 结构特征 / Structure

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 ● 铁芯
心。免维护、安装简便，综合运行成本低、损耗低、防潮性能好，可 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
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 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
电量低、噪音小，散热能力强，强迫风冷条件下可以 120% 额定负载 及紧固件经表面处理以防止锈蚀。
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 此外，本公司还开发了多阶步叠铁芯工艺，铁芯由剪切线自动堆栈，
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， 铁芯成型采用不叠上铁轭方案，有效地降低了空载损耗、空载损耗、
产品的可靠性指标达到国际先进水平。 空载电流和铁芯噪音。
It is safe, non-pollute,and flame proof, which can be installed directly on the ● core
load center with the merits of free maintenance, easy installation, low combined Core alignment with high-quality cold-rolled silicon steel material, 45°miter
operationcost,low loss and excellent humidity resistance. The transformer can joints structure, stem with insulation tape binding, the core surface is sealed
be operated normally under 100% humidity and put into motion without dry in with insulating resin paint rust proof, clamps and fasteners surface treated
advance when out of use It shares the properties of low partial electricity local with prevent corrosion.
discharge, low noise and large heat dispel capability, it can be operated with In addition, the company also developed a multi-stage step-stack core
the rated load of 120% under the forced air cooling conditions. With perfect technology, the core stack automatically by the shear line, forming the core
temperature protectcontrol system to ensure safty operation of the transformer does not use the stack of yoke program, effectively reducing the load loss,
Referring to the operation research of10 thousand transformers have been load loss, no-load current and the core noise.
putto use, their reliability norm have reached advanced international standard.
