Abstract

The invention relates to the technical field of electric energy meters, in particular to a self-ash-cleaning electric energy meter which comprises an electric energy meter body. The electric energy meter body is provided with a rotating column, a folding sleeve and an overturning plate; a contraction groove is formed in the front face of the electric energy meter body, the folding sleeve is installed in the contraction groove through the rotating column, and an air blowing nozzle is installed on the folding sleeve. One end of the turnover plate is hinged to the electric energy meter body, and the bottom of the turnover plate is connected with the folding sleeve; a display screen is arranged on the front face of the electric energy meter body and located below the contraction groove. The overturning plate rotates in the direction away from the contraction groove, so that the folding sleeve is unfolded, and the blowing nozzle faces the display screen. The technical problem that in the prior art, dust is prone to being accumulated on the display screen, and normal use of the electric energy meter is affected is effectively solved.

Description

technical field [0001] The application relates to the technical field of electric energy meters, in particular to a self-cleaning electric energy meter. Background technique [0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric watt-hour meter, a fire meter, or a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. [0003] When using the energy meter, it should be noted that in the case of low voltage (not exceeding 500 volts) and small current (tens of amps), the energy meter can be directly connected to the circuit for measurement. In the case of high voltage or high current, the electric energy meter cannot be directly connected to the line, and needs to be used with a voltage transformer or a current transformer. [0004] When it is necessary to repair the electric energy meter, a layer of dust will accumulate on the surface of the electric energy meter after it has been us...
