Abstract

The invention relates to the technical field of electric power metering, and relates to a centralized power marketing metering device and a management system thereof; the centralized power marketing metering device comprises a metering box body with an opening in the front side and an electric power sampling unit; a main control unit, a positioning unit, a communication unit, a storage unit and asampling comparison unit, a display unit and an electricity larceny detection unit are arranged in the metering box body, wherein the electric power sampling unit is connected with the sampling comparison unit, the electricity larceny comparison unit and the main control unit separately; and the main control unit is connected with the positioning unit, the communication unit, the storage unit, theelectricity larceny detection unit, the sampling comparison unit and the display unit separately. According to the device, a plurality of users share one metering device in a centralized manner, andsignals in the electric circuits of the users are collected in real time through the electric power sampling unit, and whether the voltage current is too high or electricity larceny leakage occurs ornot can be judged in real time through comparison; and if the fault occurs, an alarm can be given in real time, and the working personnel can accurately and quickly determine the fault occurrence position through the positioning data.

Description

technical field [0001] The invention relates to the technical field of electric power metering, and relates to a centralized electric power marketing metering device and a management system thereof. Background technique [0002] Electric energy metering device has become an indispensable equipment in our life. The number of electric energy metering devices used is very large. At present, the electric energy metering device of residential users is one installation per household or the electric energy metering device of residential users in the same unit building is uniformly installed in the unit. In front of the building, but in fact, residential users and power companies do not use the energy metering device frequently. Only meter reading personnel perform meter reading once a month, and each energy metering device needs to consume electricity; at the same time, if the energy metering device appears Faults, the staff cannot accurately determine the location, and need to be ...
