Problems solved by technology

[0004] In the prior art, there are mainly the following types of broadband access methods: one is WIFI access, through wireless access, one of the disadvantages of this method is that it has large radiation, and the other is that the billing is based on the flow meter, so the cost is high. Uneconomical; the second is ADSL access, directly laying communication lines or using existing telephone lines to access, the defect of this method is that the speed of metal conductors is limited, and it is greatly affected by lightning; the third is LAN access, through handover For the existing buildings, this method needs to be re-wired, which will damage the existing buildings and affect the ap

Description

technical field [0001] The invention belongs to the technical field of combining electric energy metering and network communication, and in particular relates to an electric energy meter for PFTTX and a wiring method. Background technique [0002] As a tool for measuring electric energy, electric energy meters have been widely used in the electric power industry. Therefore, in the occasions where electricity is used, there are basically electric energy meters. There are two types of electric energy meters currently in use: mechanical and electronic. The function of the meter is only used for the measurement of electric energy and the transmission of the quantity of electricity. [0003] On the other hand, broadband access technology is developing rapidly, and the world is currently undergoing a transformation of "light advances and copper retreats". Since communication cables have multiple metal conductors, their lightning protection performance is very poor, and lightning o...
