2. Characteristics of 35kV oil-immersed transformer

High efficiency: The 35kV oil-immersed transformer has advanced design, high-efficiency materials and innovative manufacturing processes, which makes its energy conversion efficiency extremely high and reduces unnecessary energy loss.

Good insulation performance: As the main insulating medium, transformer oil provides excellent electrical insulation performance for the transformer and ensures the safe operation of the transformer.

Good heat dissipation performance: The oil-immersed transformer uses the thermal conductivity of transformer oil to achieve rapid heat dissipation of internal components, effectively preventing the transformer from being damaged due to overheating.

High reliability: The 35kV oil-immersed transformer has a rigorous design and high-quality materials, which can operate stably in various harsh environments, providing a guarantee for the reliable power supply of the power system.

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

3. The structure of 35kV oil-immersed transformer

The 35kV oil-immersed transformer is mainly composed of the following parts:

Iron core: The iron core is the magnetic circuit part of the transformer, which is made of high-quality silicon steel sheets, which provides a stable magnetic flux path for the transformer.

Winding: A winding is the circuit part of a transformer, usually wound from copper wire with high conductivity, which is responsible for the transmission and conversion of electrical energy.

Oil tank: The oil tank is the outer shell of a transformer, usually with a sealed structure, and the inside is filled with transformer oil for insulation and heat dissipation.

Cooling system: In order to ensure that the transformer does not overheat during high-load operation, the 35kV oil-immersed transformer is equipped with an efficient cooling system, including radiators and fans, etc.

Protection system: The transformer is equipped with a comprehensive protection system, including overload protection, short circuit protection, oil temperature protection, etc., to ensure its safe operation.

Fourth, the application of 35kV oil-immersed transformer

35kV oil-immersed transformers play a key role in the power system. In terms of power transmission, they are used to transmit voltage from the power station to the individual substations and users, ensuring the efficient and safe transmission of power. In terms of power distribution, 35kV oil-immersed transformers are used to convert high-voltage electricity into low-voltage electricity suitable for users to meet various electricity needs. In addition, they are widely used in industrial, commercial, and residential power applications.

5. Technical details and precautions

When selecting and using a 35kV oil-immersed transformer, you need to pay attention to the following technical details and precautions:

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

Insulation level: Ensure that the insulation level of the transformer matches the voltage level of the power system to prevent the occurrence of accidents such as insulation breakdown.

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.

Oil temperature monitoring: Regularly monitor the oil temperature to ensure that the oil temperature does not exceed the allowable range and prevent the transformer from overheating.

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.
