Example Embodiment

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] like figure 1 As shown, the energy meter checking system of the present invention includes two sets of energy meter checking devices and control units, and the two sets of energy meters are set, and the left and right sides of the power meter checking device are the import and exit of the electric energy meter, respectively. The outer side of the electric energy meter is inserted and the outer sides of the belt-type master belt. The main transfer belt of the imported side is used to transport the energy-sensing energy to the power meter checking device, and the main transmission belt on the outlet side is used to convert the calibration power. Table is delivered to subsequent process processing mechanisms. Two main belts are vertically set to the power meter calibration unit. An input-auxiliary unit is provided between the imported side main belt and the ene...

Abstract

The invention discloses an electric energy meter verification system, and belongs to the field of electric power metering device verification. The electric energy meter verification system comprises an electric energy meter transmission mechanism, at least one set of electric energy meter verification devices and a control unit, the electric energy meter transmission mechanism comprises a plurality of belt type main conveyor belts and auxiliary units, and the main conveyor belts are arranged at the two sides of the inlets and the outlets of the electric energy meter verification devices respectively; the auxiliary units are arranged between the main conveyor belts and the electric energy meter verification devices, and are used for sending the electric energy meters into and out of the electric energy meter verification devices; and the electric energy meter transmission mechanism and the electric energy meter verification devices are connected with the control unit. The invention further discloses a verification method adopting the electric energy meter verification system. According to the present invention, the whole-process automatic control of the electric energy meter is achieved, the manual assistance is not needed, and the verification efficiency of the electric energy meter is greatly improved.

Description

technical field [0001] The invention relates to a calibration system for electric power metering equipment, in particular to an electric energy meter calibration system and method, and belongs to the field of calibration for electric power metering equipment. Background technique [0002] Existing electric energy meters need to verify their measurement accuracy through relevant calibration equipment before they leave the factory and sell them. Unqualified products can be found in time to ensure the factory pass rate of electric energy meters. The provincial companies of State Grid and China Southern Power Grid Corporation purchase electric energy The full inspection policy will be implemented after the meter to ensure that each electric energy meter used by the user has effective functions and accurate measurement. At present, most of the power supply companies and major energy meter manufacturers still use traditional energy meter calibration devices to realize energy meter...
