Abstract: The present invention relates to an internal arc monitoring device for a gas insulation opening/closing device capable of detecting an accident (i.e. arc) inside a gas insulation opening/closing device and accurately marking the position. The internal arc monitoring device includes: one or more partial discharge sensors which measure an electromagnetic wave signal of partial discharge generated when an internal arc occurs in a gas section of a gas insulation opening/closing device; one or more gas pressure wave sensor which measure a pressure wave signal according to the expansion of gas generated when an internal arc occurs in the gas section of the gas insulation opening/closing device; a data acquisition unit which receives the electromagnetic wave signal measured by the partial discharge sensor and the pressure wave signal measured by the gas pressure wave sensor and determines the internal arc, the cause, and the position of the arc from the received measured data from the sensors; and a transmission unit which transmits the measured data from the sensors inputted from the data acquisition unit and the determination data to a higher-level system. By doing so, it is possible to quickly react to an internal arc and minimize human resources and costs for maintenance.
