The invention provides an electric energy metering device, electric meter equipment and a configuration method for the electric energy metering device, and relates to the technical field of electric power. The electric energy metering device comprises a first mutual inductor unit, a mutual inductor acquisition module and a metering module, wherein the first mutual inductor unit is used for obtaining a first detection signal corresponding to a transmission line; the mutual inductor acquisition module is used for obtaining a second detection signal corresponding to the transmission line; and themetering module is used for obtaining a first turn ratio of the first mutual inductor unit according to the first detection signal, the second detection signal and a second turn ratio corresponding to the mutual inductor acquisition module, and carrying out configuration processing based on the first turn ratio. According to the device, the electric meter equipment and the configuration method provided by the invention, the turn ratio of the mutual inductor unit configured in the electric energy metering device can be automatically configured, great deviation occurred in electric energy metering due to operation configuration errors when the turn ratio of the mutual inductor unit is configured is avoided, the accuracy of electric energy metering is guaranteed, and the cost and resourcesare saved.
Description
technical field [0001] The invention relates to the field of electric power technology, in particular to an electric energy metering device, an electric meter device and a configuration method for the electric energy metering device. Background technique [0002] In recent years, with the planning of energy Internet construction, electric energy metering devices have developed rapidly. Electric energy metering devices of different specifications have different rated currents, but in practical applications, the current to be measured is often much greater than the rated current of the electric energy metering device, so the general electric energy metering device needs to be equipped with a corresponding proportion of external transformers. use. Transformers, also known as instrument transformers, can be current transformers and voltage transformers, which can change high voltage into low voltage and large current into small current. Usually, the selection of the transforme...
