Causes of acetylene in transformer oil
The reason for the acetylene in the oil: First, the transformer oil itself contains acetylene, and second, when the oil filter is processed, the oil is locally overheated and decomposed due to electrical heating, forced filtration, or friction in the mechanical oil delivery system, resulting in hydrogen, acetylene, and methane. Wait for gas. The working principle of the vacuum oil filter should be to evaporate and separate the water, gas and low distillate from the oil. Its separation ability is related to the working vacuum, oil temperature, oil film evaporation area and evaporation time. In terms of a vacuum oil filter, its ability to separate gas is relatively fixed. However, due to the extremely small amount of moisture, gas and oil molecules have strong binding force, the separation capacity of the general vacuum oil filter is limited, so no matter how long the filter oil reaches the limit equilibrium, the oil still contains a small amount of gas and water This is why many vacuum oil filters cannot completely remove acetylene.
It is normal for the transformer oil in operation to contain acetylene, which is a parameter for analyzing the fault state of the transformer.
The acetylene in the new transformer oil is left over by the imperfect performance of the vacuum oil filter; the oil filter with excellent performance can ensure that the acetylene is zero. Please consult us for transformer oil degassing.
