Oil filled transformer is a common electrical equipment widely used in power systems. Its main function is to convert electrical energy from one voltage level to another to meet the needs of different power equipment.
The oil filled transformers working principle is based on electromagnetic induction. When the input voltage passes through the main winding, the magnetic field generated causes a change in magnetic flux in the core. This change causes a change in the voltage in the secondary winding, thereby converting electrical energy.
The oil in oil filled transformers plays an important role. It is used not only for insulation and cooling, but also for transmitting heat. The high insulating properties of oil can effectively protect the windings and core from electric shock and damage. At the same time, the cooling function of the oil can help control the temperature of the transformer to ensure its normal operation.
In addition, oil can also transfer heat, allowing the transformer to maintain a stable temperature during long periods of high load operation. Oil has high thermal conductivity and can quickly absorb and release heat, thereby maintaining the normal operating temperature of the transformer. This is critical to ensure the performance and longevity of the transformer.
Oil filled transformers are also fire-proof and explosion-proof. Due to the high insulation and heat-insulating properties of oil, it can effectively isolate and suppress the generation of arcs and prevent fire accidents. In addition, the design of oil filled transformers also takes explosion-proof measures into consideration to ensure that the transformer will not cause an explosion in the event of failure.
To sum up, oil filled transformers play an important role in power systems. It meets the needs of different devices by converting the voltage level of electrical energy. At the same time, the oil’s insulation, cooling and heat conduction properties, as well as fire protection and explosion-proof functions, ensure the safe operation and reliability of the transformer.
