Description
GS-BAN transformer oil is a kind of petroleum liquid, which is mainly used in electrical equipment such as transformers, and plays the roles of insulation, cooling and arc extinguishing.
-Insulation function: It has good electrical insulation performance, and can form an insulation layer between the winding and iron core of the transformer to prevent current leakage and short circuit and ensure the safe operation of the equipment.
-Cooling function: the transformer will generate heat when it is running, and the transformer oil will circulate to absorb heat and transfer it to the radiator, thus cooling the transformer and ensuring it to work in the normal temperature range.
-Arc extinguishing function: In the tap changer and other parts of the on-load voltage regulating transformer, when the contacts are opened and closed to generate an arc, the transformer oil can quickly extinguish the arc to prevent the arc from damaging the equipment.
Performance requirements:
-High electrical insulation strength: able to withstand high voltage without being broken down to ensure good insulation performance.
-Low viscosity: It has low viscosity, so as to facilitate smooth flow inside the transformer and improve the cooling effect.
-Good oxidation resistance: in long-term operation, it can resist oxidation, slow down the deterioration of oil quality and prolong service life.
-Low water content and impurities: Water content and impurities will reduce the insulation performance of oil, so the water content and impurity content of transformer oil need to be strictly controlled.
Scope of application:
Mainly used in all kinds of power transformers, including oil-immersed transformers, reactors and other electrical equipment. In addition, transformer oil may be used as insulation and cooling medium in some high-voltage switchgear, transformers and other electrical equipment.
