Electric energy meter table remote calibration device and automatic calibration method

Abstract

The invention discloses an electric energy meter table remote calibration device and an automatic calibration method; the electric energy meter table remote calibration device comprises a data processing platform (1), a data receive main station (2), a data receive slave station (3), a three-phase standard electric energy meter (5), a single-phase standard electric energy meter (6) and a magnetic field intensity meter (8); the data processing platform (1) and the data receive main station (2) are connected through the Ethernet; the data receive main station (2) and the data receive slave station (3) are connected through the Ethernet; the data receive slave station (3) is connected with a relay (4) through a wireless mode; the three-phase standard electric energy meter (5) and the single-phase standard electric energy meter (6) are arranged on an electric energy metering standard calibration table (7), and connected with the relay (4) in a wireless mode; the magnetic field intensity meter (8) is arranged in a position 1-3 meters away from the electric energy metering standard calibration table (7); the invention also discloses the automatic calibration method, and aims to solve the problems that a conventional electric energy metering management mode is poor in information communication, regular device calibration caused by geography dispersion wastes manpower and materials, and the work efficiency is low.

Description

technical field [0001] The invention belongs to the field of electric energy measurement, and relates to a remote verification device and an automatic calibration method for electric energy meters. Background technique [0002] Electric energy has become an indispensable source of energy in daily life. It is used in all aspects of life and production. Electric energy measurement is related to the vital interests of every customer. With the market-oriented operation of electric energy trading, the accuracy and reliability of electric energy measurement It has been paid more and more attention by power grid companies and all parties involved in power trading. [0003] Usually in each province, the management of electric energy metering is mainly managed by the personnel of the electric energy metering center, and the electric energy metering instruments of the local power supply departments scattered in various places are regularly calibrated to ensure the accuracy of electric...

Problems solved by technology

[0004] However, in the traditional way, the personnel of the electric energy metering center must regularly transport the verification equipment from the center to various local power supply departments, and they need to be equipped with full-time personnel to go there. Due to the limitation of manpower and material resources, the personnel of the electric energy metering center are often exhausted for a long time. The long-term transportation process of the equipment often leads to a decrease in the accuracy of the verification equipment itself or other problems, resulting in extremely low efficiency. In some areas, due to the quality problems of the electric energy metering equipment itself, the verification results of a large number of electric energy meters deviate, which affects the accuracy of the electric energy metering work. normal operation

The verification of the electric energy meter is often due to poor manpower and related electric energy metering equipment parameter information, which leads to the personnel of the electric energy metering center not having enough information on the accuracy of the electric energy metering equipment in the scattered power supply departments, which brings losses to customers
