Abstract

The invention provides a charged pluggable high voltage electric energy metering device which comprises a combined mutual inductor fixedly arranged on a metering cabinet back plate, a main metering drawer and an auxiliary metering drawer. A first A-phase electric energy metering component and a first C-phase electric energy metering component are arranged on the main metering drawer and form a main meter metering device together. A second A-phase electric energy metering component and a second C-phase electric energy metering component are arranged on the auxiliary metering drawer and form an auxiliary meter metering device together. The invention further provides a charged pluggable high voltage electric energy metering method. The structural mode of the metering drawers is adopted, and field mounting, detection, comparison and replacement of a user are facilitated better. Double-metering-drawer design is adopted, a standard meter can carry out charged detection on a main meter conveniently, the device and method can be used for field metering and comparison on the main meter and an auxiliary meter, the aim of metering data redundancy is achieved, and data are safer and easier to restore.

Description

Technical field [0001] The invention belongs to the technical field of electric energy metering, and specifically relates to a 3-35kV live pluggable high-voltage electric energy direct metering device and method, in particular to a drawer-type high-potential direct electric energy metering and an electric energy metering device with the characteristics of main and auxiliary meters . Background technique [0002] Although the existing 3-35kV high-voltage electric energy direct metering device has the advantages of small size, light weight, saving metal materials, checking overall errors, and effectively avoiding electricity theft, there are also some problems, mainly because it is difficult to conduct on-site inspection and live replacement. [0003] According to the national and industry standards for electric energy measurement, the electric energy metering device (electric energy meter) that calculates the cost shall be inspected regularly on site according to the capacity of the...
