Abstract

The embodiment of the invention discloses a method for realizing power frequency anti-creeping and an electric energy meter, and the method comprises the steps: recognizing the specification constantof the electric energy meter, and calculating the starting power and starting time of a metering chip according to the specification constant; reading current data, active power and pulse signal behaviors in the operation process of the electric energy meter; judging whether the current data is smaller than a current preset threshold value or not, and if the current data is smaller than the current preset threshold value, immediately resetting the value of a fast pulse counter in a metering chip; judging whether the active power is smaller than a preset power threshold value or not, and if theactive power is smaller than the preset power threshold value, immediately resetting the value of a fast pulse counter in a metering chip; and judging whether a pulse signal behavior exists within the anti-creeping time, and if no pulse is generated within the anti-creeping time, immediately resetting the value of a quick pulse counter in the metering chip. According to the embodiment of the invention, 0.5 mT power frequency anti-creeping can be carried out under the condition that no component is added.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method for realizing power frequency anti-creep movement and an electric energy meter. Background technique [0002] With the development and progress of the electric energy meter industry, the industry gradually tends to increase the anti-creep test requirements under 0.5mT power frequency magnetic field in the electric energy meter testing items. Its purpose is to analyze the fault characteristics of the electric energy meter under the power frequency magnetic field, and detect whether the electric energy meter has antimagnetic measures against the power frequency magnetic field, so as to ensure that the electric energy meter can accurately measure the test in the power frequency magnetic field environment. Its technical requirements are that under 0.5mT power frequency magnetic field interference, the electric energy meter should be placed at the most sensitive place...
