Description
technical field [0001] The invention belongs to the technical field of electric power metering devices, and in particular relates to a charge control controller for a three-phase electric energy meter. Background technique [0002] As the basic equipment of smart grid construction, smart energy meters play an important role in supporting the realization of informatization, digitization, automation and interaction of the grid. Linked to the development of the smart grid, its basic function is to improve the operating efficiency of power companies, promote energy conservation and emission reduction, and enhance the stability of the power system. At present, the realization and promotion of remote fee control of single-phase smart meters has become increasingly common. However, the three-phase four-wire smart meter already has the auxiliary function of trip control. Because of the large load current, the electric energy meter itself does not have an internal control trip devic...
