35kV及以下油浸式电力变压器

Oil-immersed power transformers 35kV and below

我司提供的油浸式电力变压器，具有以下特点：

1、采用了新型绝缘结构，抗短路能力强；

2、选材优良，铁芯由优质冷轧硅钢片或具有极低损耗的非金合金铁心材料；高低压绕组均选用优质高导电率材料。

3、用计算机对电场，磁场，温度场及冲击场进行精确的分析与计算，确定其相应的结构与设计参数，使冲击场强和梯度合理分布，保证性能优良可靠，同时经济技术指标优良。

4.采用了降低场强设计，局部放电量小。

5.采用真空注油全密封免维护设计，终身无需维护，使用寿命长。

Oil-immersed power transformers provided by our company have the following characteristics:

1, the use of a new insulation structure, strong resistance to short circuit;

2. Excellent material selection, the core is made of high-quality cold-rolled silicon steel sheet or non-gold alloy core material with extremely low loss; High and low voltage windings are selected high quality high conductivity materials.

3. The electric field, magnetic field, temperature field and impact field are accurately analyzed and calculated by computer, and the corresponding structure and design parameters are determined, so that the impact field intensity and gradient can be reasonably distributed, and the performance can be guaranteed to be excellent and reliable, and the economic and technical indicators are excellent.

4. The design of reducing field intensity is adopted, and local discharge is small.

5. Vacuum oil injection complete seal maintenance free design, no maintenance for life, long service life.
