Transformer oil gas chromatograph can realize instant vaporization injection of packed column, large-diameter capillary column injection, capillary column split injection and fixed volume gas injection of plane rotary valve according to the analysis needs of actual samples. A kind of cracker for cracking chromatographic analysis. Mainly divided into the following steps:
1. Take out a certain amount of transformer oil
First, prepare a certain amount of transformer oil. After the color of the transformer oil changes, use a test tube or a syringe to extract a certain amount of transformer oil and put it into a glass container for use.
2. Separation of gas in transformer oil
Transfer the spare transformer oil into the vacuum degassing device, and use the working principle of the degassing device to separate gas and liquid to separate the various gases and oily liquids dissolved in the transformer oil, so as to facilitate the subsequent detection work .
3. Detected by the authenticator
After the gas is separated from the transformer oil liquid by the degassing device, the separated gases are loaded into the identifier one by one. The gas identifier will make corresponding identification data according to the chemical composition and composition of different gases, and through the computer The display system converts its relevant properties into electronic data for human analysis.
4. Determine the type of failure
According to the identification of the gas type contained in the oil of the transformer by the appraiser, the type of fault that occurs inside the transformer can be determined. And take effective repair methods to repair the fault in time to avoid greater losses due to the damage of the transformer.
