Oil immersed power transformer is a very important equipment that undertakes the important responsibility of transmitting, distributing, and converting electrical energy in the power system. In the power industry, oil-immersed power transformers are widely used in transmission, transformation, and distribution processes. So, what exactly is an oil immersed power transformer? Let's take a closer look.

Oil immersed power transformer, as the name suggests, is a "power transformer immersed in oil", and its oil pool is usually filled with transformer oil, which is called a transformer oil immersed power transformer. Just like the lubricating oil we usually use, transformer oil plays a role in lubrication, rust prevention, and cooling in the oil pool. In power transmission, transformer oil can also isolate air and moisture, avoid coil short circuits, and thus play a role in isolation, energy storage, transmission, and distribution of electrical energy.

In practical applications, oil immersed power transformers have a very wide range of applications, such as high-voltage transformers, medium voltage transformers, low-voltage transformers, Autotransformer, three-phase transformers, etc. Among them, high-voltage transformers are mainly used for transmission, while medium and low voltage transformers are mainly used in substation and distribution systems. Autotransformer are mainly used in inductors and transformers, and three-phase transformers are widely used in power systems in various fields.

 

Compared to ordinary power transformers, oil-immersed power transformers have many advantages. Firstly, the thermal conductivity of oil is higher than that of air, which can better dissipate heat and effectively avoid the problem of transformer overheating. Secondly, the insulation performance of oil is better than that of air, which can effectively protect the coil and prevent electric shock. In addition, oil-immersed power transformers also have the characteristics of self cooling, self-protection, and low noise, which can better meet the needs of modern power systems.

 

Although oil immersed power transformers have many advantages, there are also some issues that need to be noted. Firstly, the oil needs to be regularly replaced and old oil should be phased out to avoid affecting the operation of the power system due to poor oil quality. Secondly, the oil pool should avoid touching water and moisture to prevent the impact of rust and oxidation. Therefore, we must pay attention to maintenance and upkeep when using this equipment.

 

In short, oil-immersed power transformers are important equipment for transmitting, distributing, and converting electrical energy in the power system. They have a wide range of applications and many advantages, but they also require attention to maintenance and upkeep. I believe that with the development of the power industry, this type of equipment will gradually become more popular and modern, and can better serve the power system

 

 

Oil immersed transformers have the following advantages:

 

Good insulation performance. The transformer oil of oil-immersed transformers has good insulation and thermal conductivity, while the transformer oil is cheap.

It can solve the problem of high capacity heat dissipation and high voltage insulation in transformers.

Advanced design. The oil immersed transformer adopts advanced design concepts, with high-quality materials, scientific formula, and strict technology, ensuring the high quality of the product.

 

Energy conservation and environmental protection. Oil immersed transformers have low losses, good power saving effects, and can operate economically without maintenance.

Small size, relatively light weight, and low installation cost.

Pressure relief valves are installed on oil transformers with a capacity of 30-2000kVA. We can install gas relays with alarm and trip terminals according to user needs.

 

All thermometers are equipped with glass type tube holders, which are designed at the top of the fuel tank and are about 120mm deep inside the tank. Outdoor signal thermometers are installed on oil immersed transformers of 1000-2000kva for precise observation.

There will also be more advantages in delivery, installation, and various services.
