Abstract

PURPOSE:To realize the high-accuracy measurement of the temperature, by providing the indirect pocket filled with the oil into the insulating oil in the oil pouring electric apparatus and then keeping the constant pressure within the indirect pocket via the buffer part comprising the bellows attached to part of the indirect pocket. CONSTITUTION:Indirect pocket 4 filled with oil 3 is provided into insulating oil 2 of oil electric apparatus 1, and buffer part 4a comprising the bellows or the like is attached to part of pocket 4. When the temperature of oil 2 increases, the liquid within temperature sensing part 5 is heated up via oil 3 withih pocket 4. And with the expansion of the liquid, the pressure is transmitted to indicating part 6 via capillary tube 7. Thus the displacement is given to the bellows or the Bourdon tube within part 6 to indicate the temperature. At this moment, the pressure increment due to the expansion of the oil in pocket 4 is absorbed by part 4a and with the temperature increase. Thus the pressure can be kept constant within pocket 4, ensuring the high-acuracy measurement of the temperature.
