概 述 

全密封电力变压器取消了储油柜，用波纹油箱本体的翅板作为散热冷却元件，同时随着变压器油的增减而 胀缩，使变压器内部与大气隔离，防止油的劣化和绝缘受潮及老化，增强了运行的可靠性。铁心采用优质冷轧 硅钢片，有效的改善了磁通密度在铁心内部的分布状况，降低了嗓声，降低了损耗。线圈选用高强度漆包线 （或纸包线）卷绕，圆筒式(或饼式）结构，安匝分布均匀，绝缘结构合理，具有很强的 抗短路能力。油箱内使 用的紧固件均采用止退螺母，能保证长途运输后运行时不至于松脱。油箱表面经磷化处理后用三防漆（防潮、 防霉、防盐雾）涂装，广泛应用于治金、矿山、石化等使用环境较恶劣的场合。

summary

         The oil conservator is canceled for the fully sealed power transformer, and the fin plate of the corrugated oil tank body is used as the heat dissipation and cooling element. At the same time, the expansion and contraction of the transformer oil increase and decrease, so as to isolate the inside of the transformer from the atmosphere, prevent the deterioration of the oil and the moisture and aging of the insulation, and enhance the reliability of operation. The iron core adopts high-quality cold-rolled silicon steel sheet, which effectively improves the distribution of magnetic flux density in the iron core, reduces the noise and reduces the loss. The coil is wound with high-strength enamelled wire (or paper-clad wire), cylindrical (or cake) structure, with uniform ampere-turn distribution, reasonable insulation structure and strong short-circuit resistance. The fasteners used in the oil tank are all retaining nuts, which can ensure that they will not loosen during operation after long-distance transportation. After phosphating treatment, the surface of the oil tank is coated with three-proofing paint (moistureproof, mildew-proof, salt spray proof), which is widely used in occasions where the use environment is relatively bad, such as gold treatment, mining, petrochemical and so on.
