Can transformer insulating oil burn?
2024-08-09
Transformer insulating oil can burn under certain conditions. This is because.
Characteristics of insulating oil: Although the insulating oil in the transformer has a high flash point (generally not less than 135°C), it may still burn under specific conditions. For example, when a short circuit, overload or other faults occur inside the transformer, the insulating oil will decompose due to high temperature and produce flammable gas, which may form an explosive mixture after mixing with the air, and may burn or even explode once it encounters a spark or an electric arc.
Oil deterioration and external factors: insulating oil, if used for a long time or contaminated, may deteriorate and reduce its flash point and stability, thus easier to burn. In addition, external factors such as lightning overvoltage, operational overvoltage, etc. may also cause the transformer internal flash arc, resulting in insulating oil combustion.
Improper design or maintenance: If the transformer design is unreasonable or improper maintenance leads to low oil level, poor heat dissipation, etc., may also increase the risk of insulating oil combustion.
In conclusion, although transformer insulating oil is not easy to burn under normal conditions, the possibility of burning increases significantly when specific conditions and faults occur. Therefore, proper maintenance and monitoring is the key measure to prevent transformer insulating oil burning.
