      35KV oil immersed transformer

      Oil-immersed transformer is a common electrical equipment, mainly used for converting AC voltage. The following is a brief introduction to oil-immersed transformers:

      Working principle: Oil-immersed transformer converts high-voltage electrical energy into low-voltage electrical energy through the action of transformer, or vice versa. It mainly consists of iron core, winding and insulating oil.

      Insulating oil: The inside of the transformer is filled with insulating oil. This oil is not only used to cool the transformer, but also improves the insulation performance and prevents breakdown.

      Heat dissipation: Oil-immersed transformers dissipate heat through the circulation of insulating oil to ensure that the transformer maintains an appropriate temperature during operation.

      Application: Oil-immersed transformers are commonly used in industrial fields, power systems, and large buildings to convert voltage, protect circuits, and transmit electrical energy.

      In general, oil-immersed transformers are reliable and efficient power equipment that are widely used in various fields to support the normal operation of power systems.

      The role of oil in oil-immersed transformers

      Insulation. Transformer oil has a higher dielectric strength than air, which can improve the insulation strength between the windings and other electrical components, while protecting them from moisture erosion.
      Heat dissipation. Because transformer oil has a large specific heat capacity, it is used as a coolant to help dissipate heat generated during transformer operation and keep the transformer within a safe operating temperature range.
      Arc Cancellation. On oil circuit breakers and transformer on-load voltage regulator switches, transformer oil can quickly extinguish arcs as they are generated, increasing the safety of the equipment.
      Mechanical support and corrosion protection. Transformer oil can provide certain mechanical support, enhance the mechanical strength of the transformer, and extend the service life of the oil by adding corrosion inhibitors and antioxidants.
      Reduce partial discharge and gas generation. Transformer oil absorbs and dilutes gases generated in the windings and other components, reducing the risk of partial discharges and thus extending the service life of the equipment.
      Provides pressure equalization. In the event of a change in pressure within a transformer, oil can help maintain pressure balance and prevent excessive internal pressure.
