PROBLEM TO BE SOLVED: To detect abnormality of a capacitor by a simple configuration.SOLUTION: A capacitor abnormality detection device 4 for detecting the abnormality of a capacitor 3 includes the capacitor 3 where the outer periphery is formed including a cover part 3b covered with a cover member and a conductor 3a not covered with the cover member, and an electric circuit having at least an electrode 41, a power supply 42, and a resistor 43. When there is no abnormality in the capacitor 3, the conductor 3a and electrode 41 are disposed at the position facing each other while separated from each other, and when the internal pressure of the capacitor 3 increases and the conductor 3a bulges, the conductor 3a and electrode 41 comes into contact with each other so as to be disposed at a position where a current flows through the electric circuit.SELECTED DRAWING: Figure 3 |
