Oil Immersed Hermetically Sealed Type Transformer

Oil immersed hermetically sealed type transformer is a new type of high-performance transformer with reasonable structure and excellent performance. Due to the three-dimensional arrangement of its three core columns in equilateral triangles, the three-dimensional winding iron core has no air gap in its magnetic circuit and is wound more tightly. The lengths of the three magnetic circuits are the same and the shortest. The cross-sectional area of the transformer core column is closer to circular, which further improves performance, reduces losses, lowers noise, balances the three terms, and reduces the third harmonic component. This product is more suitable for urban and rural, industrial and mining enterprise power grid renovation, and is more suitable for combination transformers and pre installed transformers for substations.

(1)Product Feature
● Lower Temperature Rise And Long Service Life
In the operation of transformers, temperature rise is a key factor reflecting product reliability and safety. On the basis of finite element method temperature distribution analysis, the coil design was carried out using computer simulation technology to adjust the oil passage structure of oil immersed hermetically sealed type transformer, reduce current density, and effectively reduce temperature rise, ensuring the reliable operation time of the transformer. The service life of the transformer exceeds 20 years..
● Lower Noise And High Level Of Energy-Saving
By using advanced upgrade technology and computer technology to effectively control magnetostriction, and utilizing materials such as damping rubber plates, the noise generated by the transformer during operation has been effectively reduced. Its sound intensity level exceeds Chinese standards, with a noise diffusion rate of 58 decibels, reaching the international advanced level among peers.
● Strong Short-Circuit Withing Strength
The short-circuit withstand strength is a key factor reflecting the reliability of transformers. By analyzing the leakage magnetic field of the transformer, the ampere turns balance and electromagnetic force of Yuanchen immersed hermetically sealed type transformer have been reasonably distributed. In addition, the use of advanced process equipment and high-grade, high-precision advanced materials for the transformer fully meets the requirements for short-circuit withstand voltage strength..
(2)Application
● Projects To Upgrade Rural Power Grids
Low load rate (usually 10-40%), significant energy-saving benefits.
● Urban Power Distribution Network
Residential communities, commercial centers, and other places with high requirements for power supply quality.
● Renewable Energy Projects
Intermittent energy access systems such as wind and solar power.
● Industrial Power Distribution System
Large factories and enterprises that are sensitive to operating costs.

● Computer Technology Assisted Design
Using computer technology to design the internal iron core layout of the product, ensuring that the equipment can maximize its efficiency during actual operation. By analyzing the magnetic field and current situation, transformers can be designed more in line with the needs, saving costs while ensuring product safety.
● Advanced Technology And Rich Experience
Whether during transportation or operation, the fuel tank must be absolutely sealed under mechanical stress. We have advanced production equipment and processing technology, which can handle welding work with high quality and quantity. Moreover, we have strict and professional workflows and measures, and with rich shipping experience, we can ensure the safe delivery of equipment.
● Pay Special Attention To Anti-Corrosion Treatment
The surface of each iron core is pre treated and treated with phosphating acid to prevent corrosion. The process of anti-corrosion treatment, like multi-layer coating, involves multiple layers of treatment, each with a preset drying time. And according to the requirements, the equipment can also be hot-dip galvanized to provide better protection and extend its service life.

● Strict Quality Assurance:
The product has passed the routine, type, and special tests conducted by the China Electrical Product Quality Supervision and Inspection Center, China High and Low Voltage Electrical Product Quality Supervision and Inspection Center, China Energy saving Product Certification Center, and China Quality Center.
● Advanced Production System:
The factory has ISO9001 quality management system certification and ISO14001 environmental management system certification.
