油浸式配电变压器
Oil-immersed distribution transformers BODA TRANSFORMER

产品介绍
Product introduction
S11、S13 系列型全密封油浸式变压器适用于交流 50Hz、额定工作电压 20kV 及以下
的电力系统中，作为石油、冶金、化工、纺织、轻工等企业及粉尘较大场所的配电变
压器。
S11 and S13 series fully sealed oil-immersed transformers are applicable to
power systems with an ac 50Hz and rated working voltage of 20kV and below, as
distribution transformers for petroleum, metallurgy, chemical industry, textile, light
industry and other enterprises and places with large dust.
产品特点
Characteristics of the product
● 铁芯
铁芯选用高导磁晶粒取向冷轧硅钢片。铁芯为新式铁芯，全斜接缝迭积式铁芯，其铁
芯柱为多级阶梯的圆截面，铁轭与铁芯为等截面。
● 绕组
绕组采用瓦楞油道，不浸漆工艺，紧缩带绑扎；绕组均为同心式线圈：高压绕组具有
对应分接电压要求的抽头，引至分接开关上，开关安装在箱盖上、且需切断电源后方
可变换分接电压。
● 安全保护装置
30~2000kVA 变压器装有压力释放阀；
10KV、20KV,S11/S13 根据用户需求可安装具有报警和跳闸端子的气体继电器；
油浸式配电变压器 ● 油温测量装置
Oil-immersed distribution transformers 变压器均装有玻璃温度计的管座，管座设在油箱顶部，伸入油内 120±10mm;
1000~2000kVA 变压器装有户外式信号温度计；
● 变压器油箱
型号含义
The meaning of model 变压器油箱由波纹壁构成，表面采用粉尘
喷涂、漆膜牢固。波纹散热片不但具有冷却功能，而且具有“呼吸”功能，波纹散热
片的弹性可补偿因温度升降而引起的变压器油体积的变化。因此全密封变压器没有储

油柜，降低了变压器整体高度；
变压器在封装时采用真空注油工艺，完全去除了变压器中的潮气，变压器油不与空气
高压侧电压等级 接触。有效地防止氧气和水分侵入变压器而导致变压器绝缘性能下降和变压器油老化

的可能，因此不定期进行油样试验；
容量 (kVA)
capacity (kVA) ● core
全密封 Core is made of high permeability grain oriented cold-rolled silicon steel. The core
of the new core, miter joints convolution type iron core, its legs of circular cross
Sealed section multi-step, the yoke and the core of constant section.
设计序号 ● winding
Design No. Windings corrugated oil passage, not dipping process, tightening belt lashing;
concentric coil windings are: high voltage winding has a corresponding tap tap
三相 voltage requirements, lead to a tap on the switch, the switch is mounted on the
Three phase cover, and the need to cut After the power supply before converting voltage tap.
● security devices
30~2000kVA transformer equipped with a pressure release valve;
Can be installed with alarm and trip relays gas terminals according to user needs;
● oil temperature measurement device
Headers transformers are equipped with a glass thermometer, tube socket located
on the top of the tank, inserted into the oil 120±10mm;
1000~2000kVA transformer type equipped with outdoor thermometer signal;
● transformer tank
Constituted by a corrugated wall transformer tank, the surface dust www.cnboda.cn
Spray, paint firm. Corrugated fins not only has a cooling function, but also
changes in the volume of transformer oil "breathe" elasticity, corrugated fins may
compensate for temperature caused by lifting. Therefore, there is no conservator
sealed transformer, the transformer reduces the overall height;
Transformer vacuum oiling process at the time of packaging, completely removes
moisture 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;
