AI Technical Summary

Technical Problem

In environments with high dust concentrations, existing electricity metering boxes gradually accumulate a large amount of dust on their dustproof mesh, resulting in insufficient airflow, affecting heat dissipation efficiency and metering accuracy, and potentially causing equipment temperature to rise and service life to shorten.

Method used

It adopts an intelligent dust-removing power metering box, equipped with a wind speed sensor and controller. Through an automated cleaning structure and a back-blowing structure, it monitors the air intake in real time and cleans the dust screen when necessary to ensure permeability.

Benefits of technology

It achieves automated cleaning of the dustproof net, reduces the need for manual maintenance, improves heat dissipation efficiency, extends the service life of the equipment, reduces the workload of operation and maintenance, and ensures the stable operation of the metering box.

Abstract

The application discloses an intelligent dust-removing type electric energy metering box, and relates to the technical field of electric energy metering boxes.The electric energy metering box comprises a metering box body, two protective doors are arranged on the side of the metering box body, a first cavity and a second cavity are arranged in the metering box body, an electric energy meter and a small circuit breaker are arranged in the first cavity, a plastic shell type circuit breaker is arranged in the second cavity, a heat dissipation fan is fixed to the side of the metering box body, and a controller is fixed to the side of the metering box body, away from the heat dissipation fan.The air inlet of the air inlet pipe is intelligently monitored in real time through the wind speed sensor.When the air inlet cannot meet the heat dissipation demand, the driving motor is started, the cleaning brush is reciprocally moved, dust attached to the dust screen is automatically and intelligently cleaned, the dust on the dust screen is reduced, the permeability of the dust screen is ensured, and the influence of the dust screen blockage on the heat dissipation of the whole metering box can be effectively avoided.
