Reasons and preventive measures for gas generation in transformer oil

1, Reasons for Gas Generation in Transformer Oil
1. Oil quality issues
Poor quality of transformer oil can lead to an increase in sublimated and volatile substances, resulting in the production of gases in the oil.
2. High temperature
In the case of long-term overload or short-term overheating of transformers, the high temperature of transformer oil will promote the evaporation of volatile components in the oil, thereby producing gases.
3. Excessive humidity
If there is moisture in the transformer insulation oil, it will generate moisture vapor at high temperatures, causing gas to be produced in the oil.
4. Excessive oxygen content in oil
If the oxygen content in transformer oil is too high, it will react with organic substances in the oil and produce gas.
2, The hazards of gases in transformer oil
1. Affects the performance of transformers
The presence of gas in transformer oil can affect the insulation and discharge performance of transformers.
2. Damage to equipment
When too much gas is generated in the transformer oil, it will accelerate the aging of the oil, reduce the insulation effect, and cause damage to the transformer equipment, shortening the service life of the transformer.
3, Preventive measures for gases in transformer oil
1. Optimize the quality of oil products
Optimize the quality of transformer oil, select transformer oil that meets standards to prevent poor oil composition, and regularly maintain and replace the oil.
2. Control the temperature of the transformer
When the transformer is overloaded or overheated, the load should be immediately reduced or the machine should be stopped for cooling, and the temperature of the transformer should be controlled within a reasonable range to reduce the risk of gas generation in the oil.
3. Control the humidity of the transformer
During storage and transportation, attention should be paid to moisture and water resistance, and regular testing and maintenance should be carried out.
4. Prevent oxygen from entering the transformer oil
During the production process, attention should be paid to the sealing of the pipeline system to prevent oxygen from entering the transformer oil, and regular testing and maintenance should also be carried out.
