Abstract

The invention discloses an electric energy metering terminal and an electrical fire monitoring method. The electric energy metering terminal comprises a sampling unit, a judgment unit and a processing unit, wherein the sampling unit is used for acquiring leakage current on a load line of the electric energy metering terminal in real time through a high-precision residual current transformer; the judgment unit is used for judging whether an electrical fire happens or not according to the leakage current which is acquired from the load line in real time; the processing unit is used for controlling on and off of a circuit load through a preset switch according to a judgment result whether the electrical fire happens or not. The electric energy metering terminal integrates a fire monitoring function, so that the electrical fire is prevented; timely circuit on-off processing is carried out on the happened fire, so that the spreading speed of the electrical fire is greatly reduced; besides, safety guarantee of the rescue work is provided for fire extinguishing, and the electric shock event in a fire extinguishing process is avoided.

Description

technical field [0001] The invention relates to electrical fire monitoring technology, in particular to an electric energy metering terminal and an electrical fire monitoring method. Background technique [0002] Electrical fire monitoring belongs to the early pre-alarm system. Different from the traditional automatic fire alarm system, the early alarm of the electrical fire monitoring system is to avoid losses, while the traditional automatic fire alarm system is to reduce losses. Electrical fires and traditional fires usually exist at the same time and affect each other. Building fires occur frequently, which will cause huge losses to the country and people's lives and property. The number of fires caused by electrical faults and the losses caused by electrical fires accounted for the first place in all types of fires. [0003] When a fire occurs, in order to ensure the safety of fire fighting, it is generally required to immediately cut off the power of the building on ...
