Automation Operation and Maintenance of Three-Phase Energy Meters

With the continuous development of the socio-economy and the gradual improvement of industrial levels, mechanical and electronic technology, information technology, and control technology have also found new development space. As one of the main tools for measuring electricity in production and life, the operation efficiency of three-phase electric meters will largely determine the detection efficiency of electricity in production and life.

Overview of the automated calibration system for three-phase electric meters

In the past production and life, the manual method was usually used to calibrate the electricity measuring equipment. However, this calibration method not only has low work efficiency and high operation cost, but also cannot meet the establishment of electricity consumption information collection systems and the promotion of intelligent electric meters in various enterprises' production.

With the continuous development of society and the gradual improvement of scientific and technological levels, electronic technology, automated information collection technology, and intelligent calibration technology have also been developed accordingly. In this large context, automated calibration systems have also emerged. In the process of operation, automated calibration systems can not only complete automated transmission of information, but also realize automated information, data processing, and full monitoring of electronic-style electric meters. It can be said that the establishment of an automated calibration system for three-phase electric meters can fundamentally achieve automated information calibration and unmanned value guards for electric energy information. At the same time, in this system, multiple technologies such as automated transmission, management, and security monitoring of information have been applied, which has improved the production process of three-phase electric meters and is a major reform project for intelligent information measuring equipment in the electric energy industry.

Maintenance and improvement of the automated calibration system for three-phase electric meters

The automated calibration system for 3 phase electric meter is mainly composed of calibration devices and automated equipment, and the automated equipment and calibration devices involved are relatively mature product equipment. However, in order to adapt to the particularity of the automated calibration system for three-phase electric meters, some non-standardized product equipment must be added, such as programming keys and automatic sealing devices in three-phase electric meters. The addition of this part of product equipment will cause certain problems related to the reliability and stability of operation during the operation of the automated calibration system for three-phase electric meters.

In the process of maintaining the reliability and stability of the programming key triggering mechanism and automatic sealing device of the automated calibration system for three-phase electric meters, the invalid state of the programming switch should be added to ensure the safe operation of the automated calibration system for three-phase electric meters. After this action is completed, the programming switch of the overall automated calibration system for three-phase electric meters should be set to a state of 3 minutes, including the setting of the effective and invalid states of the programming switch for the three-phase electric meter automated calibration system.

The effective state of the programming switch for the automated calibration system of the three-phase electric meter can be entered by clicking the programming button during the setting process, and it can be programmed or unable to be programmed. The implementation of this function fully meets the requirements of the power grid. The invalid state of the programming switch for the automated calibration system of the three-phase electric meter, during the setting process, the automated calibration system of the three-phase electric meter will always remain in the state allowed by the programming system. At this time, the switch indicator light of the program will indirectly flicker, and it cannot be exited from the programming state in any way.
