35kV及以下油浸式電力變壓器

Oil-immersed power transformers 35kV and below

我司提供的油浸式電力變壓器，具有以下特點：

1、采用了新型絕緣結構，抗短路能力強；

2、選材優(yōu)良，鐵芯由優(yōu)質冷軋硅鋼片或具有極低損耗的非金合金鐵心材料；高低壓繞組均選用優(yōu)質高導電率材料。

3、用計算機對電場，磁場，溫度場及沖擊場進行精確的分析與計算，確定其相應的結構與設計參數，使沖擊場強和梯度合理分布，保證性能優(yōu)良可靠，同時經濟技術指標優(yōu)良。

4.采用了降低場強設計，局部放電量小。

5.采用真空注油全密封免維護設計，終身無需維護，使用壽命長。

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.
