Problems solved by technology

[0002] Under normal circumstances, the replacement of the old and new electric energy meters requires a power outage operation, but in some special occasions such as special enterprises or hospitals, the electric energy meter cannot be cut off during the replacement process, that is, the electric energy meter must be replaced without interruption There is a certain time interval (half an hour or even longer) between the old electric energy meter and the installation of the new electric energy meter. Statistics are inaccurate, resulting in the problem of missing electricity

Embodiment Construction

[0014] A method for supplementary measurement and supplementary calculation of electric energy meter replacement and missed reading electricity of the present invention:

[0015] The current smart energy meters have freezing functions, including timing freezing and designated freezing. Through the freezing function, all electric energy meters can be read and received at the same specific time according to the demand.

[0016] (1) Install a temporary meter (hereinafter referred to as C meter) before the old meter (hereinafter referred to as A meter) is removed. The installation method is a series connection mode to provide uninterrupted power supply to the user. The meter starts measuring;

[0017] (2), issue a freeze command, instruct meter A and meter C to freeze the electricity, and copy the frozen electricity indications as A2 and C2 respectively;

[0018] (3) Bypass the current output terminal of meter A, stop the electric energy measurement of meter A, and copy the numbe...

Abstract

The invention belongs to the technical field of electric power measurement and relates to a complementary measurement and complementary calculation method for the missed reading of an electric quantity during the replacement of an electric energy meter. According to the method, a temporary meter is installed, the electric quantity of the temporary meter, the electric quantity of a new electric energy meter and the electric quantity of an old electric energy meter are calculated in real time in the electric energy meter replacement operation process, and based on the electric quantity statistics of the three electric energy meters, a new formula is adopted to calculate the electricity consumption statistics in a non-power-outage meter replacement operation period. Compared with the prior art, the method solves the problem that the reading of an electricity consumption quantity is missed in the process of replacing the electric energy meter without power outage.

Description

technical field [0001] The invention relates to the technical field of electric power metering, in particular to a supplementary measurement and supplementary calculation method for electric energy meter replacement and missed reading electricity. Background technique [0002] Under normal circumstances, the replacement of the old and new electric energy meters requires a power outage operation, but in some special occasions such as special enterprises or hospitals, the electric energy meter cannot be cut off during the replacement process, that is, the electric energy meter must be replaced without interruption There is a certain time interval (half an hour or even longer) between the old electric energy meter and the installation of the new electric energy meter. Statistics are inaccurate, resulting in the problem of missing electricity. Contents of the invention [0003] In order to solve the defects and problems existing in the electric energy meter in the prior art t...
