Title: ELECTRICITY METER AND ELECTRICITY METER FIRE OUTBREAK LOCATION IDENTIFICATION METHOD
Abstract:
Provided are an electricity meter and electricity meter fire outbreak location identification method which make it possible to determine whether an increase in the temperature of the main body of the electricity meter is due to an external fire outbreak or internal fire outbreak, and to leave behind the determination results. Thus, an electricity meter (1A) for adding up the electricity use amount is provided with: an internal measurement temperature sensor (25) for detecting an increase in the internal temperature of the main body of the electricity meter; an abnormality determination control unit (13c) which, on the basis of the speed of the increase in internal temperature, determines whether the internal temperature increase is due to the outbreak of a fire outside the main body of the electricity meter or to the outbreak of a fire inside the main body of the electricity meter; and an external communication unit (14) which externally transmits the determination results of the abnormality determination control unit (13c).
