However, the equipment has some defects, as the deterioration rate of insulating oil in the equipment is mainly influenced by the content of each substance in the area, when the external oxygen concentration and the water molecule content are higher, the corrosion rate of a sealing assembly can be increased, the amount of oxygen and water molecules entering the oil body can not be controlled after the sealing performance is reduced, the equipment can not sample the built-in oil body in a staged manner, and the content of related substances is detected, so that the blindness of later manual investigation is higher, and the optimal oil body replacement time is easily missed.
