Õlisoolatsiooniga

Õlisoolatsiooniga refers to a method of insulation that utilizes oil as the insulating medium. This technique is commonly employed in electrical equipment, particularly in transformers and high-voltage switches. The oil used is typically mineral oil or synthetic ester oil, chosen for its excellent dielectric properties, which prevent electrical arcing and breakdown.

The primary function of oil insulation is to provide a barrier that resists the flow of electric current. In transformers, the oil not only insulates the windings from the core and casing but also serves as a coolant, dissipating the heat generated during operation. This dual role is crucial for the longevity and efficiency of the transformer.

In high-voltage switchgear, oil insulation allows for the safe interruption of electrical circuits. When a switch is opened, the oil surrounding the contacts quenches the arc that forms, preventing damage to the equipment and ensuring safe operation. The oil's ability to absorb energy from the arc is key to its effectiveness in this application.

The properties of the insulating oil, such as its dielectric strength, viscosity, and flash point, are carefully selected and maintained to ensure optimal performance and safety. Regular testing and maintenance of the oil are essential to detect any degradation or contamination that could compromise its insulating capabilities. Over time, oil can degrade due to oxidation, moisture absorption, or the presence of other impurities, necessitating replacement or reconditioning. The use of õlisoolatsiooniga is a well-established and reliable method for ensuring electrical safety and operational integrity in various high-voltage applications.
