Problems solved by technology

At present, only the power outage of the entire station area can be performed, and the concentrator will send the power outage information to the main station; for power outages caused by branch switches in the power distribution room, branch switches in the building / meter box, disconnection of the switch in front of the meter, or aging or damage of the line Still unable to intelligently judge
[0004] In terms of the operation monitoring of the entire meter box, the current collector can only monitor the daily frozen electric energy indications of all the smart energy meters in the meter box. The main problem at present is that it is impossible to know the voltage, current, power, total It is more difficult to detect the voltage, current and cause of the fault at the moment of power failure and power failure and report it quickly

Abstract

The invention discloses intelligent low voltage collection complete equipment and a dual channel collection method of low voltage collection. The intelligent low voltage collection complete equipmentcomprises a cable branch box monitoring unit, a meter box monitoring unit, and a main control unit. After the complete equipment is applied to a low voltage network, (1) power on-off of the meter, meter box, cable branch box, and distribution network of the low voltage network can be precisely positioned in real time, and the results can be automatically reported; (2) the 15 minute voltage, current, power, and value curve of the meter box branch switch side and the user intelligent electric energy meter side are collected high-frequently; and (3) after the accidents of power on-off of each grade, the low voltage collection equipment reports the results to a main station system within one minute. The main station system accurately reports the power off accidents to a power supply service command system in real time, the power supply service command system precisely positions and alarms power off clients in a GIS map, the accuracy and timeliness of maintenance are both improved, inactivemaintenance becomes active maintenance, the maintenance efficiency is improved, and the service quality is improved.

Description

technical field [0001] The invention relates to a low-voltage intelligent collection complete set device in the field of low-voltage distribution network electric energy information collection, in particular to a low-voltage intelligent collection complete set device and a low-voltage collection dual-channel collection method. Background technique [0002] The smart energy meter hung under the low-voltage station area of ​​the low-voltage distribution network is directly facing the user, which is the nerve ending of the smart grid; as the grid company develops the smart meter to support the operation and maintenance management of the distribution network, the range and frequency of power information collection data and The function is not enough to meet the needs. The current low-voltage acquisition equipment in the low-voltage station area mainly includes concentrators, collectors and their subsidiary low-voltage carrier modules. The collection and networking method is tha...
