On-Line Monitoring System for Low-Voltage Distribution Lines

Abstract

The invention discloses an on-line monitoring system for low-voltage power distribution lines, which includes a low-voltage power failure monitoring terminal, a communication adapter and an intelligent public transformer terminal. The low-voltage power outage monitoring terminal performs data interaction with the communication adapter installed in the station area through a micro-power wireless method. The data is sorted and processed and then transmitted to the remote monitoring master station system. The low-voltage power failure monitoring terminal includes a microprocessor, a power supply and a wireless communication terminal. The wireless communication terminal is provided with a communication encryption chip adapted to the encryption protocol of the communication adapter. The power supply includes a power failure detection circuit and a charging control circuit. In the state of power failure of the power distribution line, the charging control circuit provides the working voltage to the microprocessor, and collects electric energy from the power storage circuit when the state of power failure is not detected by the power failure detection circuit.

Description

technical field [0001] The invention relates to the improvement of the low-voltage power distribution line structure of the power grid. Background technique [0002] In the low-voltage distribution line on-line monitoring system, the low-voltage outage monitor is mainly used as the data acquisition device installed at the end of the low-voltage distribution network. This device has been practically promoted in some areas. Most of the traditional blackout monitoring equipment only have the functions of live display and local viewing, and cannot transmit information remotely, let alone comprehensively analyze the collected data. For the distributed equipment in the distribution station area, the low-voltage outage monitoring device currently installed cannot meet the requirements of the standard to connect to the power intranet and assume that it is directly connected to the public network, resulting in the inability to share and integrate the data of the master station. The ...
