Abstract

The present invention relates to the technical field of electric energy meter cleaning, and discloses an electric energy meter calibration and cleaning device. The drive shaft is driven to rotate by a motor, and the rotation of the blades draws external air into the air inlet pipe, and the air is guided into the inner cavity through the air inlet pipe. After entering the inner cavity, the air enters the heating channel in the heating box and is heated by multiple heating nets. The heated air flows to the universal tube and is ejected through a nozzle at one end of the universal tube to form a small concentrated airflow that is sprayed toward a position that needs to be cleaned. The jet direction can be adjusted by the universal tube so that the heated air is sprayed to the position that needs to be cleaned, especially a narrow position. Therefore, the electric energy meter calibration and cleaning device can be used to clean water droplets or dust on the surface of the electric energy meter, and the cleaning is thorough and efficient.

Technical Field

[0002] An energy meter, also known as a watt-hour meter, is an instrument used to measure electrical energy consumption. It records the amount of energy consumed by an electrical device over a specified period of time, typically displayed in kilowatt-hours (kWh). Energy meters are crucial for the economic operation of power systems and the settlement of electricity bills for power users. To ensure the accuracy, reliability, and traceability of energy meters and ensure they provide accurate measurement results, they undergo a series of regular inspections, tests, and calibrations to confirm that they meet specified metering requirements. This process is commonly referred to as meter verification.
