Title:
ELECTRIC ENERGY METERING TERMINAL AND ELECTRICAL FIRE MONITORING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/115848
Kind Code:
A1
Abstract:
An electric energy metering terminal and an electrical fire monitoring method, comprising: a sampling unit, used for acquiring a leakage current on a load line of the electric energy metering terminal in real time by means of a high-precision residual current transformer (300); a determining unit, used for determining whether an electrical fire happens according to the leakage current on the load line acquired in real time (301); and a processing unit, used for controlling on and off of a circuit load by means of a preset switch according to the determining result indicating whether the electrical fire happens (302). By integrating a fire monitoring function into the electric energy metering terminal, an electrical fire can be prevented; by carrying out timely circuit on-off processing on a happening fire, the spreading speed of the electrical fire can be greatly reduced, safety guarantee of the rescue work is provided for fire extinguishment, and an electric shock incident in the fire extinguishing process is avoided.
