Predicting deterioration makes power equipment safer and reduces damage such as accidents to society as a whole. The present invention relates to an oil-immersed transformer among power equipment. For conventional oil-immersed transformers, deterioration of the transformer can be predicted by oil analysis, etc., but extracting oil involves time and impacts on customers such as equipment power outages and pole downs. is the current situation. A conventional oil extraction method is shown and explained in FIG. Currently, oil is collected by opening the lid 1 in FIG. 3 or from the oil extraction port 2. At this time, air chamber 3 in Figure 3
It is difficult to extract the dissolved gas.

することとなる。``The problem that the invention aims to solve'' In recent years, prediction of deterioration of power equipment has become popular. Since oil-immersed transformers account for a large proportion of power equipment, prediction of deterioration in oil-immersed transformers is becoming popular, but deterioration prediction has not yet been established. A method for predicting deterioration of oil-immersed transformers is to extract gas contained in oil or air. However, although many conventional oil-immersed transformers have the function of extracting oil, few have the function of extracting both gas and oil. Gas analysis of oil-immersed transformers can improve accuracy by analyzing gases in the oil and air. Therefore, it has become necessary to be equipped with a sampling device that can easily collect gases in oil and air. Measurement accuracy can be improved by analyzing and measuring both gases in oil and air. Improved accuracy can predict deterioration of oil-immersed transformers, and in particular can prevent oil-immersed transformer accidents due to internal deterioration.
This will provide stability in the power supply and contribute to the current electric society.

First, FIG. 1 shows a state in which the sampling device 4 of the present invention is attached to an oil-immersed transformer. The gas sampling tube 4a is installed in the air, and the oil sampling tube 4b is installed in the oil. Next, a method for collecting gas and oil from the sampling device installed as described above will be described with reference to FIG. The lid 4e of the oil sampling device shown in FIG. 2 is removed, and the needle of the syringe is inserted into the airtight gasket 4c to collect gas. At this time, be careful to make sure that the air in the syringe is zero. Furthermore, oil is collected by using a tube such as a rubber tube instead of the syringe needle, and connecting one end of the tube to the syringe and the other end to the oil collection tube 4b. As with gas sampling, the air inside the syringe must be reduced to zero. Finally, the structure will be described using FIG. 2.
The oil sampling pipe 4b is inserted into the gas sampling pipe 4a and supported by a support 4d to form a double pipe structure. In addition, by inserting a security gasket 4c, the airtightness between the outside air and the internal gas is maintained, and by screwing into the gas sampling pipe 4a using the oil extraction device lid 4e and the oil extraction device lid gasket 4f, it is shut off from the outside air. I do.
