An accident point locating device for locating whether an accident has occurred, which comprises: a conductive film of a predetermined pattern attached to the coating of a metal container for each block; an energizing circuit that energizes the conductive film; and an energizing circuit. 1. A fault point locating device for a gas-insulated switchgear, comprising a signal generator that detects a flowing current and generates a fault detection signal when the current disappears or drops below a predetermined level. (2) The accident point locating device for a gas-insulated switchgear according to claim 1, wherein the conductive film is made of a film that burns out when exposed to high heat from a metal container. (3) The conductive film is made of a film whose resistance value increases as the temperature rises, and the signal generator has a circuit that maintains the output of the accident detection signal even after the current flowing through the current-carrying circuit is restored. The accident point locating device for gas insulated switchgear according to claim 1. (4) The accident point locating device for a gas insulated switchgear according to any one of claims 1 to 3, wherein the conductive film is provided in a pattern distributed over almost the entire outer surface of the metal container of each block.
