気機器を提供することである。At this time, the temperature distribution of the insulating oil in the equipment storage chamber in the height direction increases from the lower part to the upper part of the oil-filled electric machine as shown in FIG. Insulating oil near the maximum temperature inside the storage room flows. As a result, the temperature of the insulating oil inside the oil expansion chamber increases, and the chemical reaction between the insulating oil and oxygen in the air is accelerated, whereby the insulating oil deteriorates quickly and the life of the insulating oil is shortened. In order to eliminate this drawback, there is a type in which a rubber bag is used inside the oil expansion chamber to shut off the insulating oil and the atmosphere, and the air in the rubber bag communicates with the outside air. In this case, when the temperature of the insulating oil inside the oil expansion chamber increases, the temperature of the rubber bag deteriorates quickly. In order to avoid this drawback, the former type employs a design in which the oil temperature is lowered so that the insulating oil can withstand the required service life, or a method of filling nitrogen into the air chamber. In the latter type, a rubber having a high heat-resistant grade was selected and used. To take such measures, oil-filled electrical equipment becomes large,
Alternatively, there is a disadvantage that the structure becomes complicated or the price becomes high. Further, when a failure occurs inside the oil-filled electric device, gas may be generated.
Some gas detectors, which detect a failure by the generated gas, are attached to the oil-filled electric equipment. However, in the conventional equipment, since the communication part is communicated with the oil expansion chamber from the upper part of the equipment storage chamber, the generated gas flows into the oil expansion chamber, and a failure may not be found,
A device must be provided so that gas does not flow into the oil expansion chamber. Therefore, there were drawbacks that the structure became complicated and the price became high. SUMMARY OF THE INVENTION An object of the present invention is to provide a small and inexpensive oil-filled electrical device which improves the disadvantages described above, such as an increase in the size of the oil-filled electrical device, a complicated structure, and a high price.

In this embodiment, the present invention is applied to an oil-immersed transformer. A transformer main body 2 corresponding to an electric equipment main body is accommodated in a transformer tank 1 which is an equipment storage room, and is filled with an insulating oil 3 which is a cooling medium of the transformer main body 2. The use of the transformer body 2 generates heat. The insulating oil 3 absorbs this heat and expands. A conservator 4 is provided to absorb the expansion amount of the insulating oil 3. Reference numeral 5 denotes a communication member which communicates between the conservator 4 and the vicinity of the bottom of the transformer tank 1.

が得られる。When a transformer is used, the temperature of the insulating oil 3 in the transformer tank 1 increases as it goes upward to absorb heat from the transformer body 2. By communicating the conservator 4 with the vicinity of the bottom of the transformer tank 1 where the temperature of the insulating oil 3 is low, the lower insulating oil 3 flows into the conservator 4. Since the low temperature insulating oil 3 flows into the conservator 4, the average oil temperature in the conservator 4 decreases, and in the case of the conservator 4 in which the oil comes into contact with the atmosphere, the chemical reaction with oxygen in the air is suppressed. The effect of preventing the deterioration of the insulating oil 3 is obtained.

抑制する効果がある。This is a conservator of the type in which the rubber bag 6 is housed inside the conservator 4 and is connected to the moisture-absorbing respirator 8 via the connecting pipe 7 so that the inside of the rubber bag 6 communicates with the atmosphere. When the volume of the insulating oil 3 increases and the insulating oil 3 flows into the conservator 4 through the communication member 5, the rubber bag 6 contracts. Thereby, the expansion and contraction of the insulating oil 3 can be absorbed without coming into contact with the atmosphere. Therefore, as in the first embodiment, the oil temperature in the oil expansion chamber is reduced, so that the temperature of the rubber bag 6 is also reduced, which has the effect of suppressing the deterioration of the rubber bag.
