Electric energy meter for PFTTX (power fiber-to-the-x, x = H for home, P for premises, C for curb and N for node or neighborhood) and wiring method

Abstract

The invention belongs to the technical field of combination of electric energy metering with network communication, and relates to an electric energy meter for PFTTX (power fiber-to-the-x, x = H for home, P for premises, C for curb and N for node or neighborhood), which comprises a measurement mechanism, a shell, a display unit and a wiring unit, wherein wiring terminals are arranged on the wiring unit, and the measurement mechanism is positioned in the shell. The electric energy meter for PFTTX is characterized in that: a fiber input interface and a fiber output interface are arranged on the left side or right side or lower side of the shell, and an optical signal transceiving device is also arranged in the shell; the fiber input interface is connected with an input end of the optical signal transceiving device, and the fiber output interface is connected with an output end of the optical signal transceiving device; the fiber input interface can be externally connected with a fiber, and the fiber output interface can be externally connected with the fiber; grooves for fixing are arranged on both the fiber input interface and the fiber output interface, and threads are arranged at the outer parts of the fiber input interface and the fiber output interface; and a switch for controlling a power supply of the optical signal transceiving device is also arranged on the wiring unit. The invention also discloses a wiring method of the electric energy meter. The invention has the following beneficial effects that: the structure is simple, the use is convenient, the manufacture, the installation and the maintenance are easy, and the like.

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...

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 appearance. In addition, the factors affected by lightning have not been ruled out, and the power supply is required in the transfer box. Therefore, it is quite cumbersome to apply to the power department, and the cost of the transfer box, the construction of the machine room, and the laying of the lines are very high, which is not economical; the fourth is optical fiber access, which also requires wiring for existing buildings. However, since the medium is non-metallic, the line itself will not be affected by lightning, but for new buildings, it is necessary to lay lines many times, so the cost is high; the fifth is cable TV line access, which also has the above-mentioned disadvantages
