Product Structure

铁心:选用优 质冷轧硅钢片和多组全斜接缝步进搭接、绑扎结构,有效的 改善了磁通密度在铁心内部的分布状况,满足变 压器低损耗和低噪声的节能环保要求。

绕组:选用优质无氧铜材/高强度漆包线(或纸包线)卷绕和多层圆筒式(或饼式/螺旋式)结构,安匝分布均匀,绝缘结构合理。高压绕 组和低压绕组可采用联体绕制,效率高,线圈紧实。并通过优化冷却、散热/温升设计,对绕组线匝进行绑扎、夹紧和 对绕组端部用层压木压实,以增强 绕组机械强度和短路承受能力,确保变 压器安全可靠地运行。

器身:采用免 吊芯和器身四周限位及吊板结构,有效地 解决了器身悬空问题,器身不会位移,避免了 运输颠簸对产品质量的不利影响;器身所 使用的紧固件均采用自锁螺母,能保证 长途运输后不至于松脱。因此,新产品 在投运前无需检查。

油箱:选用波 纹油箱或膨胀式散热器油箱结构,免维修、无渗漏、体积小、散热好、结构新颖,取消了 储油柜及吸湿器,油体积 的变化依靠波纹油箱波纹片或膨胀式散热器的弹性来补偿、调节,随着温度升高/降低、变压器 绝缘油的增减而胀缩,同时使 变压器内部与空气隔离,变压器 绝缘油不与氧气和水份接触,减缓绝 缘油和纸等材料的老化速度,可延长产品使用寿命。并且油 箱密封处采用耐油硅胶密封件,不易老化、开裂,使用多年无需更换。然而,新产品运行维护简单,为用户 节省了停电维护的费用。

表面处理与涂层:零部件、油箱表 面经磷化处理后用三防漆(防潮、防霉、防盐雾)喷涂,可以满 足各种不同的使用环境,保证表 面处理涂层不脱落、无锈蚀,色泽新鲜、光亮,外形美观。

Iron core: it chooses the high-quality cold-rolled silicon steel sheets and multi groups entire ramp lap joints, banding structure. It effectively improved the distribution of the magnetic flux density within the iron core, and it met the requirements of low loss, low noise, energy saving and environmental protection of the transformer.

Winding: it chooses the high quality non-oxygen copper materials/ high strength enamelled wire (or paper-covered wire) winding and multilayer cylinder structure, even distributing ampere turns and reasonable insulation structure. High and low voltage windings can adopt the union winding, so the efficiency is high with the coil compaction. And by optimizing and cooling, heat dissipation/ temperature rise design, turn on the winding line for banding, clamping, and by the end of the winding wood laminate compaction, in order to enhance mechanical strength and short-circuit winding capacity, to ensure safe and reliable operation of the transformer.

Body: it adopts the structure of suspended core free and spacing around the body and hanging board, so that it solved the problem of body hanging in the air and the body can’t displace, at the same time, it avoided the bad impact to the product’s quality of the bumps on the transportation; The fastener using in the body adopts the locknut which can guarantee it wont get loose on the long distance transportation. Therefore, the new product is no need for inspection before putting into operation.

Tank: to choose the structure of corrugated tank or radiator expansion tank, maintenance-free, non-leaking, small size, good heat dissipation, novel structure, while canceling the oil storage tank and the moisture absorber, the changing of oil volume is regulating by the corrugated tank plates or the flexibility of radiator expansion tank. As the temperature is raised/ reduced, the increase or decrease in the transformer insulation oil is expansion or contraction, at the same time, it separates the transformer inside with the air, the transformer insulating oil does not touch with the oxygen and water, so that it will reduce the aging speed of insulating oil and paper materials to extend the using life of the product. Besides this, the seal of the tank adopts the oil proof silica gel seal parts, it is resistant to aging and crack, so that it can be used for many years without replacement. However, the operation and maintenance of the new product is simple, it is saving the cost of maintenance of power for the customers.

Surface treatment and coatings: the spare parts and tank surface are spray painting by three anti-paints (anti-damp, anti-rot, anti-salt fog) after phosphating, to meet a variety of use of the environment and to ensure that the coating surface treatment does not fall off, no rust, the color is fresh, bright, beautiful appearance.
