产品特点 /Characteristics of the product

● 铁芯 ● core
Core is made of high permeability grain oriented cold-rolled silicon steel.
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， The core of the new core, miter joints convolution type iron core, its legs
其铁芯柱为多级阶梯的圆截面，铁轭与铁芯为等截面。 of circular cross section multi-step, the yoke and the core of constant
section.
● 绕组
● winding
绕组采用瓦楞油道，不浸漆工艺，紧缩带绑扎；绕组均为同心式线圈：高压绕组 Windings corrugated oil passage, not dipping process, tightening
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 belt lashing; concentric coil windings are: high voltage winding has a
电源后方可变换分接电压。 corresponding tap tap voltage requirements, lead to a tap on the switch,
the switch is mounted on the cover, and the need to cut After the power
● 安全保护装置 supply before converting voltage tap.
● security devices
30~2000kVA 变压器装有压力释放阀； 30~2000kVA transformer equipped with a pressure release valve;
根据用户需求可安装具有报警和跳闸端子的气体继电器； Can be installed with alarm and trip relays gas terminals according to
user needs;
● 油温测量装置 ● oil temperature measurement device
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; 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 变压器装有户外式信号温度计； 1000~2000kVA transformer type equipped with outdoor thermometer
● 变压器油箱 signal;
● transformer tank
变压器油箱由波纹壁构成，表面采用粉尘 Constituted by a corrugated wall transformer tank, the surface dust
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 Spray, paint firm. Corrugated fins not only has a cooling function,
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 but also changes in the volume of transformer oil "breathe" elasticity,
器没有储油柜，降低了变压器整体高度； corrugated fins may compensate for temperature caused by lifting.
Therefore, there is no conservator sealed transformer, the transformer
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 reduces the overall height;
空气接触。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 Transformer vacuum oiling process at the time of packaging, completely
器油老化的可能，因此不定期进行油样试验； 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;
