Abstract

The invention provides an open-close type B-PLC intelligent electric energy meter capable of meeting the requirements on uninterrupted installation and intelligent management. The open-close type B-PLC intelligent electric energy meter comprises a main body of the electric energy meter and a current transformer, wherein the main body of the electric energy meter comprises a power module, a metering module, a B-PLC module, a display screen and a B-PLC communication line; the current transformer is provided with an open-close clamping groove; the power module and the B-PLC module are both electrically connected with the metering module; the metering module is electrically connected with the display screen; the power module, the metering module and the B-PLC module are all electrically connected with the B-PLC communication line; and the metering module is provided with a sampled signal input interface of the current transformer (CT). The open-close type B-PLC intelligent electric energy meter has the advantages of uninterrupted installation, high integratability, improvement on resource utilization ratio and convenient intelligent management.

Description

technical field [0001] The invention relates to an intelligent electric energy meter, in particular to a switchable B-PLC intelligent electric energy meter, which can be installed without power failure. Background technique [0002] The whole world is already in the era of smart grid. The core of smart grid is smart energy meter, which must have high-speed two-way communication function. The communication of the energy meter includes wireless and wired, and the wired communication includes a dedicated communication line (RS485 communication, etc.) and power line carrier communication. Power line carrier communication is the most ideal, and using one's own power line to communicate saves labor and materials. B-PLC (Broadband-Power Line Communication) technology has been passed by the international ISO (passed on July 31, 2009), and it is a mature power line carrier communication technology. [0003] In addition, the replacement of traditional energy meters will bring great ...
