Transformer solutions in the energy field

Abstract

‌Transformer ‌is a device that uses the principle of electromagnetic induction to change the alternating current voltage. It is widely used in the field of energy. Voltage conversion and transmission, efficient transmission of electric energy, system stability and reactive power support, grid interconnection and layered operation, isolation and fault protection and other functions need transformers to achieve. The importance of transformer manufacturing to the energy industry cannot be ignored. Then what kind of transformer to choose becomes a very important question. With the increasingly fierce market competition, cost-effective transformers are more popular. To this end, our company provides a one-stop solution to help customers easily choose the right transformer.

Key words: energy industry, transformer

Industry overview

The energy industry has a basic and pillar position in the national economy, and is of great significance to national security, social stability and people's living standards. ‌Stable supply and efficient use of the energy industry is a key factor in ensuring national security, promoting social stability and improving people's living standards ‌.

With the global emphasis on green and low-carbon development, transformers as key equipment for energy transmission and conversion will play an increasingly important role in the energy field. The continuous progress of technology and the continuous support of policies will further promote the development of the transformer market ‌.

Overall, the market demand for transformers is expanding. ‌

System composition and main functions

The voltage transformer is a static induction device that transmits AC power by changing the voltage. In order to transmit electrical energy, the AC voltage and current of one system are converted to the voltage and current of another system by electromagnetic induction at the same frequency, and the values of these currents and voltages are usually different. A transformer consists of an iron core (or magnetic core), coils, insulation and a housing. The coil has two or more windings, of which the winding connected to the power supply is called the primary coil, and the remaining winding is called the secondary coil.

Transformers are adapted to a variety of equipment requirements. Whether in industry, rail transit or energy, transformers can flexibly adjust voltage levels according to equipment needs, ensuring that all types of equipment get the right power supply.

Solutions of transformer use in the energy field

There are several key factors to consider when choosing a transformer in the energy sector ‌, including load requirements, voltage levels, efficiency and energy consumption, cooling methods, noise control, ease of maintenance and economy. After many studies and investigations, we have come up with a one-stop solution for the use of amorphous alloy oil immersed transformers in the energy sector.

The benefits of this solution are as follows:

1.High efficiency and energy saving: Amorphous alloys have high permeability and low loss because of their high permeability and low coercivity. The high saturation flux density and strong anti-saturation ability of amorphous alloy make the transformer not easily saturated under high current conditions, which improves the carrying capacity of the transformer. In addition, the eddy current loss of amorphous alloy is much smaller than the core made of cold-rolled silicon steel sheet, so the no-load loss of amorphous alloy transformer is very low, and the energy saving effect is remarkable ‌.

2.Environmental protection: Amorphous alloy materials do not contain harmful substances and are friendly to the environment. Due to the small size and light weight of amorphous alloy transformers, they are easy to be integrated into various power systems, which reduces the amount of material used and is in line with the concept of energy saving and environmental protection.

3.Low operating cost: Due to its high efficiency and low loss characteristics, the operating cost of amorphous alloy transformers is lower than that of traditional transformers, and it has better economic benefits in the long run. In addition, amorphous alloy transformers  has longer service life, which reduces the frequency of maintenance and replacement and further reduces operating costs. ‌‌
