油浸式变压器系列
Oil-immersed transformer series

结构特征 / Structure
● 铁芯 ● core
三角形铁芯不需裁剪及冲剪加工，消除了传统铁芯的横向、纵向接 Triangular core without cutting and punching processing, eliminating
缝，减少了磁阻；铁芯柱横截面呈圆形，铁芯的填充系数最大，三 the lateral, longitudinal seams traditional core, reducing the reluctance;
角形立体结构使它的三相磁回路相等并且最短，实现了人们梦寐以 leg circular cross-section, the maximum core fill factor, so that its three-
dimensional structure triangle three-phase magnetic circuit are equal and
求的理想变压器的铁芯结构。 shortest achieve a core structure that people dream of ideal transformer.
● 绕组 ● winding
绕组采用瓦楞油道，不浸漆工艺，紧缩带绑扎；绕组均为铜芯式线圈； Windings corrugated oil passage, not dipping process, tightening belt lashing;
高压绕组具有对应分接电压要求的抽头，引至分接开关上，开关安 both copper core coil winding; high voltage winding has a corresponding tap
tap voltage requirements, lead to a tap on the switch, the switch is mounted
装在箱盖上，且需切断电源后方可变换分接电压。 on the cover, and the need After cutting off the power supply before
● 安全保护装置 converting voltage tap.
80~1600kVA 变压器均装有压力释放阀；根据用户需求可安装具 ● security devices
有报警和跳闸端子气体继电器； 80~1600kVA transformers are equipped with a pressure release valve;Can
● 油温测更装置 be installed with alarm and trip relays gas terminals according to user
needs;
变压器均装有玻璃温度计的管座，管座设在油箱顶部，伸入油箱内 ● more oil measuring device
120±10mm; Headers transformers are equipped with a glass thermometer, tube socket
容量在 1000kVA 以上的变压器装有户外式信号温度计； located on the top of the tank, inserted into the fuel tank 120 ± 10mm;
● 变压器油箱 Capacity over 1000kVA transformer type equipped with outdoor thermometer
signal;
变压器油箱由波纹壁构成，表面采用粉尘静电喷涂，漆膜牢固。波 ● transformer tank
纹散热片不但具有冷却功能，而且具有“呼吸”功能，波纹散热器 Constituted by a corrugated wall transformer tank, the surface electrostatic
的弹性可补偿因温度升降而引起的变压器油体积的变化。因此全密 spraying dust, the film firmly. Corrugated fins not only has a cooling function,
封变压器没有储油柜，降低了变压器整体高度； but also has "breathing" function, the elastic bellows radiator transformer
全密封变压器，在装配时采用真空注油工艺，完全去除了变压器中 oil can compensate for variations in volume caused by temperature lift.
的潮气，变压器油不与空气接触。有效地防止氧气和水分侵入变压 Therefore, there is no conservator sealed transformer, the transformer
reduces the overall height;
器而导致变压器绝缘性能下降和变压器油老化的可能，因此不定期 Sealed transformer, vacuum oiling in the assembly process, completely
进行油样实验。 removes moisture in transformers, transformer oil is not in contact with air.
Effectively prevent oxygen and moisture intrusion caused by transformer
insulation transformers and transformer oil aging performance possible, so
from time to time oil sample test.

工作条件 / Work condition
● 海拔高度：不超过 1000m ; ● Altitude: not exceed 1000m
● 环境温度：-40℃ ~+40℃ ● Ambient temperature: -40℃ ~+40℃
