10kv distribution network branch line abnormal power failure remote alarm device

Abstract

The invention discloses a remote alarm device for abnormal power outage of a 10kV distribution network branch line. The remote alarm device comprises a signal data acquisition circuit, a signal data judgment circuit, a communication circuit and a power supply circuit, wherein the signal data acquisition circuit is used for acquiring three-phase voltage signals from a low-voltage side of a transformer installed on the branch line and transmitting the three-phase voltage signals to the signal data judgment circuit, the signal data judgment circuit is connected with the communication circuit, the communication circuit is connected with a distribution network power supply management center, and the power supply circuit is connected with the signal data judgment circuit and the communication circuit. By using the remote alarm device, the troubleshooting time of the 10kV distribution network branch line is greatly shortened, the labor intensity of employees is reduced, the power supply reliability is improved, the undue loss is decreased, the power supply quantity is increased, the enterprise benefits and the social benefits are improved, the user satisfaction is increased, the social credibility of power supply enterprises is improved and the remote alarm device has a critical importance on the development of the intelligent management techniques of the distribution network.

Description

technical field [0001] The invention relates to a remote alarm technology for abnormal power failure of branch lines of 10kV distribution network, specifically, a remote alarm device for abnormal power failure of branch lines of 10kV distribution network. Background technique [0002] At present, the power system is fully carrying out the construction of smart grids, implementing intelligent control, intelligent management, and intelligent analysis of the entire grid, and comprehensively carrying out condition-based maintenance of grid equipment. The application of distribution network intelligent control technology has only just started, and has not been fully popularized and applied due to various reasons. For the research on distribution network power supply intelligent control technology, it mainly focuses on the implementation of intelligent control for distribution lines, transformers, ring network switchgear and other equipment. Intelligent management, intelligent ana...

AI Technical Summary

Problems solved by technology

[0003] The research on remote alarm technology for abnormal power failure of 10kV distribution network branch line will greatly promote the safe and economical operation of power distribution system equipment. The 10kV distribution network branch line system currently in operation basically has a fault because it cannot be monitored in real time. Notify the on-duty personnel to search for maintenance, the fault point is difficult to find, time-consuming, the equipment damage rate is high, and the power supply reliability is low. If the 10kV distribution network branch line abnormal power failure remote alarm technology can be fully promoted and applied, the fault search time will be greatly shortened and the labor intensity of employees will be reduced. , improve the reliability of power supply, and play a vital role in the development of grid intelligent management technology
