Abstract

The embodiment of the invention provides an electric energy meter and a surge counting method, and relates to the technical field of electric power detection. The electric energy meter comprises a sampling unit, a rectification and filtering unit, a comparison unit, a control unit and a warning unit, wherein the sampling unit, the rectification and filtering unit, the comparison unit, the controlunit and the warning unit are electrically connected in sequence; the rectification and filtering unit is used for carrying out full wave rectification and filtering processing on sampling voltage obtained by the sampling unit from a power grid to obtain processed voltage; the comparison unit is used for outputting a high level signal or a low level signal to the control unit according to a comparison result of the processed voltage and a preset voltage threshold value; and the control unit is used for updating surge frequencies when the surge happens according to the level signals, and givingan alarm through the warning unit electrically connected with the control unit when the updated surge frequencies exceed a surge frequency threshold value. By use of the electric energy meter, workers can be reminded of repairing and replacing the electric energy meter of which the surge frequency exceeds the standard so as to avoid electric energy meter power supply faults and the like, and power grid operation and maintenance quality is improved.

Description

technical field [0001] The present application relates to the technical field of electric power detection, in particular, to an electric energy meter and a surge counting method. Background technique [0002] In order to prevent the electric energy meter from being damaged due to the surge, the electric energy meter is generally provided with a pressure sensitive device, which can effectively absorb sudden huge energy (for example, the huge energy formed by the surge). [0003] However, varistors are generally consumable devices, and their lifespan will be shortened as the number of surges increases until they fail. After the pressure sensitive device fails, if the surge occurs again, the energy meter will be damaged. Contents of the invention [0004] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the embodiments of the present application is to provide an electric energy meter and a method for counting surges, which can monitor su...
