3 Phase Oil Filled Transformer

Product description：

3 Phase oil filled Transformer is an electrical appliance which uses insulating oil as insulating medium and is composed of iron core, coil, voltage regulating switch, oil tank, etc. to change the voltage and transmit AC energy.

Our company has rich product series, including laminated iron core series, amorphous alloy series and other products under 35kV.

1.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

Main features:

1.Free maintenance.

Low loss, good power saving effect, economic operation, maintenance - free

2.Environmental protection is good.

The high-voltage winding is made of enameled copper wire, while the low-voltage winding is made of copper foil.The windings are poured by imported epoxy resin in the vacuum state. After curing, they form a solid whole with good mechanical strength, small partial discharge and high reliability.

3.Flame retardant explosion-proof.

Flame retardant, explosion-proof, no pollution to the environment, can be installed in the load center.

4.Strong adaptability to the environment.

The coil does not absorb moisture. The core and clamps can operate in 100% relative temperature and other harsh environment after special processing. No dehumidification is required for intermittent operation.
