Abstract

The invention discloses an efficient method for checking the operation working condition of an electric energy meter with a comprehensive and accurate checking result. The method comprises the following steps: acquiring basic information data of the electric energy meter and site operation data, classifying the acquired data, calculating an operation state value RM of the electric energy meter, and determining an actual operation state corresponding to an actual operation working condition value of the electric energy meter. The checking method is high in efficiency; the problem that equipment which operates normally fails due to an artificial reason; by the checking method, the primary current percentage, the primary voltage percentage, the primary load power factor, the voltage waveform aberration rate, the degree of unbalance of three-phase voltage, ambient temperature, and influence of the relative humidity of the environment on the electric energy meter are taken into consideration, so that comprehensive checking on the operation working condition of the electric energy meter can be realized, and the finally obtained checking result is accurate, comprehensive and high in reliability; the method is suitable for being popularized and applied in the technical field of evaluations on the states of gateway counting equipment.

Description

technical field

[0001] The invention relates to the technical field of status evaluation of gateway metering equipment, in particular to a method for checking the operating conditions of electric energy meters. Background technique

[0002] In order to ensure the normal operation of the electric energy meter and the reliability of the measurement data, it is usually necessary to remotely estimate the operating conditions of the electric energy meter. Most of the existing inspection methods for the operating conditions of the electric energy meter use manual inspection. A large amount of manual on-site inspection and complex calculation process are required, and the work efficiency is low; secondly, when the on-site accuracy test of the electric energy meter is performed manually, the electric energy meter is repeatedly operated, which leads to the failure of the equipment that was originally in normal operation. Larger hidden dangers of failure; in addition, the existing ins...
