Description

In the power distribution network with distributed power supply, single-phase transformers have great advantages as distribution transformers. It can reduce the length of low-voltage distribution lines, reduce line losses, and improve power supply quality.

The transformer adopts a high-efficiency and energy-saving coiled iron core structure design, adopts a pole-mounted suspension installation method, is small in size, small in infrastructure investment, reduces the low-voltage power supply radius, and can reduce low-voltage line losses by more than 60%. It is suitable for rural power grids, remote mountainous areas, scattered villages, agricultural production, lighting and power use, and can also be used for energy-saving transformation of railways and urban power grids on pole-mounted distribution lines.

1、 What is an oil immersed transformer?

Oil immersed transformer, also known as oil immersed transformer, is a transformer device that uses oil cooling to reduce the temperature of the transformer. Unlike dry transformers, the main body of an oil immersed transformer is installed in a welded steel oil tank filled with insulating oil. When an oil immersed transformer is in operation, the heat from the coil and iron core is first converted into insulating oil and then into cooling medium. According to the capacity, it can be divided into immersed Free cooling transformer and immersed forced air cooling transformer.

2、 The structure and working principle of oil immersed transformers

Oil immersed transformers are structurally similar to transformers It is one of the types of transformers classified according to the insulation form of the iron core. Therefore, it has recognizable features of oil immersed coils, which can reduce the heat map of the equipment inside.

The basic components of the oil immersed type are composed of magnetic cores, windings, and bushings. The magnetic core provides a path for magnetic flux. The winding creates a magnetic field consisting of a conductor coil wound around an iron core and insulated with a cardboard barrier and shielding layer. The thickness of the winding insulation layer increases with increasing voltage. The bushing connects the transformer winding to the substation.

Oil type transformers are used for power distribution or substations. Their core and coils are immersed in oil, which can cool and insulate. Oil circulates through the pipes in the coil and around the coil and iron core components through convection. The oil is cooled externally by the fuel tank at low rated values, and by an air-cooled radiator at high rated values.

3、 Types of oil immersed transformers

There are two main types of oil immersed transformers: single-phase transformer and three-phase transformer.

A. One phase oil immersed transformer

B. Three-phase oil immersed transformer

4、 Purpose of using oil immersed transformers

Oil type transformers can be installed on the ground, base, or pole for outdoor use. They provide efficient performance in various applications, including transmission and distribution networks, renewable energy generation, and small industries.

The oil transformer has a huge capacity, so it will save a lot of electricity, minimize energy loss, save energy, and reduce user costs. Not only that, the oil in the machine can also cool the internal wire cores, thereby improving the durability and electrical performance of transformer equipment.

5、 Precautions for using oil-immersed transformers

1. Oil immersed transformers use oil for operation, so the quality of the oil will significantly affect the lifespan and safety of the transformer.

2. During use, it is necessary to regularly inspect and maintain the transformer system to ensure the normal and safe operation of the machine. Otherwise, there is a high risk of problems and extreme danger.

3. The waste generated by petroleum is prone to polluting the environment and affecting the lives of surrounding people. Therefore, the gradual disposal of waste is also important

Structural features

1. The high-voltage coil is wound with high-quality polyurethane enameled round copper wire, and the low-voltage coil is wound with cable paper-covered wire. Adhesive paper is used for interlayer insulation, which starts to melt at a certain temperature during the drying process of the coil, which produces adhesion, and begins to solidify as the temperature rises, so that the adjacent layers of the winding can be reliably bonded into a fixed unit , To prevent the displacement of the coil winding, thus ensuring the safety and reliability of the insulation structure.

2. Iron core

Using grain-oriented silicon steel sheet or amorphous alloy silicon steel sheet to make a single-phase coil core, it can ensure that the magnetic flux flow direction is consistent with the grain orientation of the silicon steel sheet, so that the excellent performance of the material can be fully utilized, and the no-load loss is far It is lower than the standard requirement, and is fastened with a special iron core curing paint, which further effectively reduces the noise level of the transformer.

3.Using a cylindrical fuel tank, the fuel tank adopts a fully-sealed structure to enhance the reliability of operation, and the normal operation is maintenance-free.

4. Other features:

One (or two) high-voltage bushings are led out from the box cover, and the bushing contains a current-limiting fuse. Equipped with one (or two) lightning arresters, installed on the wall of the box, with the end close to the outlet end of the high-voltage bushing and connected by copper tape. Equipped with a secondary disconnect switch, installed in the box, on the wall of the box is equipped with an external operating handle, overload reset and signal light. The low-voltage bushing is led out on the wall of the box. X2 is equipped with a grounding device. The high-voltage of the single bushing is led out through the high-voltage bushing around the near end, and the other end is grounded. The single-phase pole-mounted distribution transformer developed by our company is mainly for foreign export projects. The capacity can be customized from 3 to 333KVA, the input voltage is 33000/30000/17321/13800/7620/6930/6350V, the frequency is 50HZ or 60HZ, and the implementation of IEEE C57, ANSI C57, IEC76, GB10318 and other standards.
