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 a fire started inside the electricity meter or was burned from outside the electricity meter, 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 that the temperature at a first location inside the main body of the electricity meter has reached or exceeded a pre-set first threshold temperature; an external measurement temperature sensor (26) for detecting that the temperature at a second location nearer the housing of the main body of the electricity meter in comparison to the first location has reached or exceeded a second threshold temperature; an abnormality determination control unit (13c) which, on the basis of the detection results from the internal measurement temperature sensor (25) and the external measurement temperature sensor (26), determines whether the temperature at the first location reached or exceeded the first threshold temperature first or the temperature at the second location reached or exceeded the second threshold temperature first; and an external communication unit (14) which externally transmits the determination results of the abnormality determination control unit (13c).
