Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] A meter calibration table for an electric energy meter, comprising a worktable, at least one detection unit is arranged on the worktable, the detection unit includes a cylinder 4, the push rod of the cylinder 4 is connected with a push block, the The push block is fixedly connected with the support plate 2 for placing the electric energy meter, and the corresponding position of the support plate 2 is provided with a detection terminal 1. When the push rod of the cylinder 4 is pushed out, the push rod pushes the electric energy meter through the push block, so that the electric energy meter Effective contact with detection terminal 1.

[0021] Further improvements of the present invention include:

[0022] The detection units on the working table are distributed in two rows up and down, and each row has 10 groups of detection units.

[0023] The end of the su...

Abstract

The invention discloses a calibration stand for an electric energy meter. The calibration stand comprises a work table, wherein the work table is provided with at least one detection unit, the detection unit comprises a cylinder, a push rod of the cylinder is connected with a push block, the push block is fixedly connected with a supporting board for disposing the electric energy meter, a position corresponding to the supporting board is provided with detection terminals, and the push rod pushes the electric energy meter through the push block to enable the electric energy meter to effectively contact the detection terminals when the cylinder push rod is pushed outwards. According to the calibration stand, the electric energy meter is automatically sent in and out for detection through the cylinder and the supporting board, so bump damage to test probes caused by manual sending-in operation is avoided, during use, only one worker is needed to scan the bar code of the electric energy meter through a bar code gun, tasks of parameter setting, accuracy calibration and clock accuracy examination are automatically accomplished at one time through equipment. Multiple electric energy meters can be hung on the equipment at one time for detection, mutual switching between two sets is carried out for meter calibration when each of equipment operates.

Description

technical field [0001] The invention relates to electric energy meter detection equipment, in particular to an electric energy meter calibration table. Background technique [0002] Each electric energy meter needs to be calibrated for measurement accuracy, neutral current accuracy, and inspection clock accuracy in the production line. At present, each watch factory needs to transfer 3 stations to complete the above work in the production process: 1 station to calibrate the current accuracy of the zero line, 1 station to calibrate the accuracy of electric energy measurement, and 1 station to check the accuracy of the clock. The table body of each station calibration meter is generally 4 epi-positions or 6 epi-positions. In the production process, it is necessary to repeatedly load and unload the meter when it is transferred to each station, repeatedly lift and lower the power supply of the table body, and set parameters. The entire meter calibration process is cumbersome to...
