PURPOSE:To detect abnormal temperature within a container accurately from outside, by a method wherein a vibration generator is installed within a high- voltage conductor and supplied with power by a battery in which an electrode is contacted with electrolytic solution at a temperature more than prescribed temperature, and the vibration is detected from outside of the sealed container. CONSTITUTION:If a high-voltage conductor 2 generates abnormal temperature and therefore temperature rises, a bimetal element 15 as temperature detecting element is deformed and an electrode 14 supported by this element is displaced as shown in solid line and immersed in an electrolytic solution 12, thereby battery action is effected and an oscillator 11 oscillates. This oscillation is transmitted through a conductor 2 and an insulation spacer 3 to wall of a sealed container 1 and detected by an oscillation detector 8 and descriminated in a vibration detecting device i.e. vibration data processor 9 thereby generation of abnormal temperature in the high-voltage conductor can be informed. |
