Embodiment 1

[0036] as attached Figures 1 to 4 As shown, the electric energy meter calibration device includes a box body 1 and a box cover 2, and the box body 1 is provided with an electric energy meter on-site calibrator 5, a spare electric energy meter 4 and a wire slot 3. The electric energy meter on-site calibrator 5 is connected with a wireless communication device. The box body 1 is provided with a handle.

[0037] A plug 15 is arranged between the terminal 5 of the electric energy meter field calibrator and the terminal 4 of the standby electric energy meter, each terminal of the electric energy meter field calibrator 5 corresponds to a plug 15, and each terminal of the standby electric energy meter 4 corresponds to a plug 15. In this embodiment, the electric energy meter 6 to be calibrated has two terminals as an example, and the electric energy meter field calibrator 5 and the standby electric energy meter 4 respectively have two corresponding terminals.

[0038] The plug 15 ...

Embodiment 2

[0046] The method for using the energy meter calibration device includes the following steps:

[0047] A1, install the socket 7, connect the first elastic contact piece 10 with the user wire, the second elastic contact piece 14 is connected with the terminal of the watt-hour meter 6 to be calibrated, and each terminal of the watt-hour meter 6 to be calibrated corresponds to a socket 7.

[0048] The socket 7 should be installed together when the watt-hour meter 6 to be checked is installed.

[0049] A2. Check and reset the standby electric energy meter 4.

[0050] B. Close the switch 8, insert the plug 15 into the socket 7, the electric energy meter contact piece 11 corresponds to the first elastic contact piece 10, and the calibrator contact piece 13 corresponds to the second elastic contact piece 14.

[0051] When inserting the first plug 15, the user wire, the first elastic contact piece 10, the electric energy meter contact piece 11, the switch 8, the calibrator contact pi...

Abstract

The present invention provides an electric energy meter calibration device and a usage method thereof. The electric energy meter calibration device comprises a box body and a box cover, an electric energy meter on-site calibration instrument and a standby electric energy meter are arranged inside the box body, and plugs are arranged between the wiring ends of the electric energy meter on-site calibration instrument and the wiring ends of the standby electric energy meter. Each wiring end of the electric energy meter on-site calibration instrument corresponds to one plug, and each wiring end of the standby electric energy meter corresponds to one plug. The plugs comprise the calibration instrument wafers and the electric energy meter wafers, the calibration instrument wafers are connected with the wiring ends of the electric energy meter on-site calibration instrument, and the electric energy meter wafers are connected with the wiring ends of the standby electric energy meter. Insulators and switches are arranged between the calibration instrument wafers and the electric energy meter wafers, the plugs are equipped with a socket cooperatively, and the socket is equipped with the first elastic wafers and the second elastic wafers. By adopting the above technical scheme, and according to the present invention, the electric energy meters can be calibrated on sites on the condition of not stopping the power supply, and the power consumption of the users is not influenced.

Description

technical field [0001] The invention relates to the field of electric equipment. [0002] Specifically, it relates to a meter calibration device for electric energy meters and a method for using the same. Background technique [0003] At present, the calibration work of smart energy meters is divided into indoor and on-site calibration. Indoor calibration requires dismantling the energy meter from the site and returning it to the indoor calibration station for testing; on-site calibration requires the use of an electrical energy meter field calibrator On-site calibration of the meter; the above methods of Liang Hong need to suspend the user's power supply, which is cumbersome to operate and brings great inconvenience to the user. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned traditional technology, and provide a meter calibration device and its use method, which can complete the calibration o...
