10kV oil-immersed transformer is a common type of transformer in power systems, which is widely used in the field of power distribution and transmission. It has the advantages of compact structure, stable performance and convenient maintenance, and is one of the important equipment to ensure the safe and efficient operation of the power system. The following will introduce the characteristics, structure, application and related technical details of 10kV oil-immersed transformer in detail.

1. Features

The main features of the 10kV oil-immersed transformer include:

High efficiency: The use of advanced winding design and insulation materials makes the efficiency of the transformer as high as 99% or more, reducing energy waste.

Energy saving and environmental protection: The cooling medium of oil-immersed transformer is transformer oil, which has good insulation performance and heat dissipation performance, and at the same time reduces environmental pollution.

Good stability: The oil-immersed transformer has compact structure, good seismic performance, and can operate stably under harsh environmental conditions.

Easy maintenance: The oil-immersed structure of the transformer makes it relatively easy to overhaul and maintain its internal components, reducing maintenance costs.

Second, the structure

The 10kV oil-immersed transformer is mainly composed of iron core, winding, oil tank, cooling device, protection device, etc.

Iron core: The iron core is the magnetic circuit part of the transformer, which is made of silicon steel sheets and has good magnetic conductivity.

Winding: A winding is the circuit part of a transformer, usually made of copper wire. According to different voltage levels and capacity requirements, the winding can adopt different winding methods and structures.

Fuel tank: The fuel tank is the shell of a transformer, usually welded from steel plates. The inside of the tank is filled with transformer oil for insulation and heat dissipation.

Cooling device: The cooling device is used to reduce the operating temperature of the transformer and ensure the normal operation of the transformer. Common cooling methods are natural cooling and forced air cooling.

Protection device: The protection device is used to monitor the operating status of the transformer, cut off the power supply in time when the transformer fails, and protect the transformer from damage.

3. Application

10kV oil-immersed transformers are widely used in the field of power distribution and transmission of power systems. In the power distribution system, it is mainly used to reduce the high voltage to the low voltage suitable for the user; In the transmission system, it is used to transport electrical energy from the power station to the various areas where electricity is consumed. In addition, 10kV oil-immersed transformers are also commonly used in industrial, commercial and residential power fields.

Fourth, technical details

When selecting and using 10kV oil-immersed transformers, the following technical details need to be noted:

Capacity selection: Select the appropriate capacity based on actual needs to avoid resource waste or unstable operation caused by excessive or small capacity.

Voltage level: Select the appropriate voltage level according to the voltage level of the power system to ensure the normal operation of the transformer.

Cooling method: Select the appropriate cooling method according to the operating environment and temperature requirements of the transformer to ensure the heat dissipation effect of the transformer.

Insulation performance: The insulation performance of a transformer is the key to ensuring its safe operation. When choosing a transformer, you need to pay attention to the performance of its insulating material and the winding process of the winding.

Maintenance: Regularly maintain the transformer, check the status of key components such as oil level, oil temperature, winding, etc., and find and deal with potential problems in time.

In a word, 10kV oil-immersed transformer is one of the indispensable and important equipment in the power system. It has the advantages of high efficiency, energy saving, environmental protection, good stability, etc., and is widely used in the field of power distribution and transmission. When selecting and using transformers, it is necessary to pay attention to their technical details and maintenance requirements to ensure their safe, stable and efficient operation.
