Abstract

The invention relates to an electric energy meter inlet wire detection system which comprises an encoder module, a current generating module, a current sampling module, a decoder module and a code comparison module. The encoder module is used to form specific encoding information and to output the same to the current generating module. The current generating module generates a current signal containing the encoding information according to the encoding information and inputs the current signal into a user-side power line circuit. The current sampling module is used to extract current change information from the power line circuit and to output the same to the decoder module. The decoder module forms the encoding information according to the current change information and outputs the same to the code comparison module. The code comparison module performs characteristic comparison on the coding information and the pre-stored coded data to determine the state of the electric energy meter inlet wire. The electric energy meter inlet wire detection system can quickly and accurately detect the relative states of the electric energy meter inlet wire without interfering in a power supply system and power outage, and has simple operation and high efficiency.

Description

technical field [0001] The invention relates to the technical field of power system operation and maintenance, in particular to a detection system and a detection method for an electric energy meter service line. Background technique [0002] Most of the inconsistent household meters occur in the same unit of the same building, which is caused by the wrong connection of the household line of the electric energy meter. troubleshooter. [0003] The traditional solution requires the entire unit to be powered off when detecting the incoming line of the electric energy meter. The operation is very complicated to check one by one according to the direction of the cables. It is easy to expand the influence and cause inconvenience to users. [0004] It can be seen that the existing solutions are complex in operation and low in efficiency. Contents of the invention [0005] Based on this, it is necessary to provide a detection system and a detection method for the incoming line ...
