Abstract

The invention discloses a digital power source applied to a full-digital electrical energy meter. A power source capable of realizing seamless connection with the full-digital electrical energy meter does not exist at present. The invention adopts the technical scheme that the digital power source is characterized by comprising an IEC61850 digital source generating unit, a system management control unit, a power supply management unit, a display unit and a keyboard control unit, wherein the power supply management unit is connected with other units through cables; and the system management control unit performs bidirectional communication with the IEC61850 digital source generating unit, is connected with the keyboard control unit through a flat cable and is connected with the display unit through another flat cable. The digital power source can realize seamless connection with the full-digital electrical energy meter with IEC61850-9-1 and IEC61850-9-2 Ethernet fiber interfaces.

Description

technical field [0001] The invention relates to a power source of an electric energy meter, in particular to a digital power source suitable for an all-digital electric energy meter. Background technique [0002] Existing power sources can only output actual metering data such as voltage and current, which is a practical power source and cannot be seamlessly integrated with full digital energy meters with IEC61850-9-1 and IEC61850-9-2 Ethernet optical fiber interfaces Connection, currently there is no power source that can seamlessly connect with the full digital energy meter. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a digital power source to achieve the purpose of seamless connection with the full digital electric energy meter. [0004] For this reason, the present invention adopts the following technical solutions: a digital power source, which i...
