Description

technical field [0001] The invention relates to a low-voltage branch line station area identification device, which belongs to the field of power distribution detection products. Background technique [0002] In recent years, in order to achieve refined management of marketing and achieve the goal of reducing consumption and loss, power grid companies often need to collect more user data of various stations, including station information and phase information of user meters, so a proposal for the low-voltage centralized copying system is proposed. new requirements. [0003] Existing station area identification devices use the method of coupling current signals, there are signal interference and errors in actual detection, and there are inaccurate detection and wrong judgments when passing through multiple switches and nodes. The existing current comparison identification devices have a long time Asynchrony brings misjudgment to the detection process. Contents of the inven...
