However, even in such cases, the heat generation point is inside the metal hermetically sealed container, and due to the danger, especially when high voltage current is being applied, it should be removed from the outside of the metal hermetically sealed container under non-contact conditions. , it is difficult to detect an abnormal rise in temperature, and therefore,
No detection was performed. As a result, the temperature rises quickly due to the large amount of heat generated by the high voltage, which often leads to major accidents if countermeasures are taken too late.

First, if the gas insulated equipment operates normally, e.g.
If the contact state between the high voltage conductor 3 and the contact 4, which is the contact portion of the high voltage conductor 3, is also good and no abnormal temperature rise has occurred, for example, the bimetal 8a will not deform. In a normal state, for example, in FIG. 3, it is in a state of shape A, and the vibrating portion of the second vibrating body 8 is in an engaged state with the first vibrating body 7a. In this state, the impact force applied to the metal hermetic container 1 or the conductor insulating support part 2 from the outside of the metal hermetic container 1 is transmitted from the conductor insulating support part 2,
The vibrations are transmitted to the first and second vibrating bodies 7 and 8 via the high voltage conductor 3, etc., but the vibrations of the individual vibrating bodies are small, and therefore the vibrations of the first vibrating bodies 7b and 7c are small. Each vibration has its own unique vibration,
The vibration is transmitted to the vibration detector 6 and detected through the high voltage conductor 3 and the conductor insulating support part 2, or through these and the metal sealed container 1 sequentially. However, the first vibrating body 7a
and the second vibrating body 8 are engaged with each other, and the gap between them is smaller than the vibration amplitude of the second vibrating body 8. Therefore, the vibration of the second vibrating body 8 is reduced by the impact applied from the outside. portion applies an impact to the vibrating portion of the first vibrating body 7, and therefore the first vibrating body 7 generates free damping vibration of a large vibration at a constant frequency for a long time. Therefore,
By detecting this free damping vibration by the vibration detector 6 in the same manner as described above, it can be estimated that the first vibrating body 7a and the second vibrating body are engaged, and as a result, Materials that change shape depending on temperature 8
a remains in shape A without changing;
That is, it is detected that the shape remains in its original shape and there is no change in the surrounding temperature.

On the other hand, poor contact occurs in gas-insulated equipment, for example, between the high-voltage conductor 3 and the contact 4, which is the connection part of the high-voltage conductor 3, and as a result, electrical resistance increases in this part and heat is generated. As a result, when an abnormal temperature rise occurs, the temperatures of both the first vibrating body 7 and the second vibrating body 8 rise. In this case, there is no significant change in the vibration of each vibrating body. However, since the bimetal 8a also increases in temperature, it deforms in accordance with the increased temperature, for example, into a state of shape B, and as a result, the second vibrating body 8 engages with the vibrating part of the first vibrating body 7c. Therefore, when an external impact is applied to this, as described above, only unique vibrations are detected from the first vibrating bodies 7a and 7b, but free vibrations are detected from the first vibrating body 7c. Damped vibration is detected, thereby causing engagement between the first vibrating body 7c and the second vibrating body 8,
That is, it is possible to detect the deformation of the material 8a whose shape changes depending on the temperature into the shape B, that is, the occurrence of an abnormal rise in the ambient temperature.

In the above embodiment, the first vibrating body is composed of three vibrating bodies having different frequencies, the base of the second vibrating body 8 is provided with a material whose shape changes depending on the temperature, and
Although the first vibrating body 7a and the second vibrating body 8 are engaged in the normal state, the present invention is not limited to this.
The first vibrating body may be composed of a plurality of pieces having mutually different frequencies, and a material whose shape changes depending on temperature may be attached to the base of the first vibrating body together with the base of the second vibrating body, or alternatively, the first vibrating body may be It may be provided only at the base of the body to engage the first vibrating body and the second vibrating body. Furthermore, a material other than bimetal that changes shape depending on temperature may be used, and This may be achieved, for example, by engagement between the first vibrating body 7c and the second vibrating body.

As described above, according to the present invention, when an abnormal temperature rise is desired to be detected, a shock is applied from the outside of the metal sealed container and the vibration state of the first vibrating body is detected by the vibration detector, thereby detecting the inside of the sealed container. The abnormal temperature rise of the high voltage conductor can be detected in a non-contact state even under operating conditions where high voltage is applied. can be detected early and reliably, preventing gas from becoming toxic due to decomposition of insulating gas caused by abnormal temperature rise, dielectric breakdown of conductor insulation supports, burnout of connections, etc. It is possible to prevent the development of various major accidents.
