Population parameter on-line monitoring system for lightning current and work flow thereof

Abstract

The invention discloses a thunder current population parameter on-line detecting system and work procedures thereof, which relates to the thunder resisting technology of an electrical device of an electric system. The detecting system has the structure that a current sensor (1), a thunder strike signal sampling unit (9), a data receiver, a GPRS, a BT transmission unit (5), the Internet (6) and a user terminal (7) are orderly communicated; an FTP server (8) is connected with the Internet (6); a solar panel (4), a storage battery (3) and a voltage changer (2) are orderly connected; and the voltage changer (2) is respectively connected with the thunder strike signal sampling unit (9), the data receiver, the GPRS and the BT transmission unit (5). The invention has the advantages of simple structure, automatic operation, stable detection and accurate data, thunder strike data which is processed by a single chip can be transmitted to the Internet through a mobile network, and the transmitting data of the Internet can be directly transferred by a user.

Description

technical field [0001] The present invention relates to lightning protection technology for electrical equipment in power systems, in particular to a lightning current full-parameter online monitoring system and its working process; specifically, to an overhead power transmission line and lightning rod lightning current full-parameter online monitoring system and its working process , suitable for judging the form of lightning strikes on overhead transmission lines or lightning rods and measuring lightning current parameters and waveforms. Background technique [0002] The lightning accidents of ultra-high voltage transmission lines are very prominent in the operation of the power grid every year. With the rapid increase of line length, line lightning tripping accidents increased significantly. There is no clear criterion for shielding and counterattack, and it is very difficult to find the fault point, especially in mountainous and high-altitude areas. However, there are ...

AI Technical Summary

Problems solved by technology

Since the lightning strike current can range from a few kA to hundreds of kA in actual conditions, and the direction of the lightning strike also varies greatly, the protection effect of the same protection system on different lightning strikes is very different, plus the topography and meteorological factors that have a significant impact on the protection effect The complex and changeable transmission lines often have protection failures in some areas, which become vulnerable to shielding tripping accidents
