Oil-immersed transformer with winding temperature measurement function

Abstract

The invention relates to the technical field of transformers, and discloses an oil-immersed transformer with a winding temperature measurement function, the oil-immersed transformer comprises a shell and a winding, the shell is internally provided with an accommodating cavity, the winding is accommodated in the accommodating cavity, and the oil-immersed transformer comprises a fixed sensor group, a temperature sensor group and a temperature sensor group, the movable sensor group comprises a driving assembly and a movable temperature sensor, the driving assembly comprises a first driving part and a second driving part, the first driving part is used for driving the second driving part to move in the horizontal direction, and the second driving part is used for driving the movable temperature sensor to move in the vertical direction; and the second driving part is provided with a detection position close to one side of the winding and a verification position close to one side of the fixed sensor group in the moving range. According to the oil-immersed transformer with the winding temperature measurement function, the movable sensor group capable of moving between the winding and the fixed sensor group is arranged, so that the temperature measurement of a winding area and the online verification of the precision of the temperature sensor can be realized at the same time.
