Abstract

The invention provides a method and device for inhibiting an interference signal and an electricity consumption information collection system, and relates to the technical field of electricity consumption information collection of the power grid. The method comprises the steps that an isolation apparatus acquires a carrier signal through a power line, and the isolation apparatus carries out isolation processing on the carrier signal to acquire a first signal; a filtering apparatus filters the first signal to acquire electricity consumption information; and the filtering apparatus outputs the electricity consumption information through the power line. According to the method and device provided by the invention, by means of the isolation apparatus and the filtering apparatus arranged between the electric equipment of the power grid and a master station, the interference signal in the electricity consumption information is inhibited, and thus the collection success rate of the electricity consumption information is improved.

Description

technical field [0001] The present invention relates to the technical field of power grids, in particular to the collection technology of power consumption information of the power grid, specifically a method, equipment and power consumption information collection system for suppressing interference signals of power consumption information. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In order to further improve the professional management of line loss and management line loss in the same period, reduce the phenomenon of "running, dripping and leaking", further strengthen the automatic statistics and information transmission of line loss, and improve the success rate of power consumption collection, it is necessary to improve the power consumption information collectio...
