Embodiment Construction

[0026] The system of the present invention is composed of four major parts of software and hardware, which are respectively: lightning parameter acquisition part, sampling data digital processing and wireless data transmission part, Internet network, WEB server and special database management part.

[0027] The lightning parameter acquisition part includes the establishment of lightning strike sampling points for the power transmission lines and lightning protection lines on the tower. The lightning strike sensors on the line are a pair of sensor groups installed at both ends of a support rod. The pair of sensor groups are fixed on the pole insulators of their own power transmission lines at equal distances along the direction of their own power transmission lines. top; ②Establish a lightning strike sensor for the lightning protection line erected on the top of the tower pole and along the direction of the power transmission line. The lightning strike sensor is also a pair of s...

Abstract

A method for confirming thunder-strike point of electric power transmission line includes setting thunder-strike transducer on each electric power transmission line and grounding wire of electric power transmission tower, connecting said transducers to test box through lead wire, setting up special databank relating to thunder-strike information in WEB server and connecting computer of said server to Internet for accurately and timely confirming out thunder-strike point on electric power transmission line when thunder-strike is occurred on certain position of electric power transmission line and grounding wire.

Description

technical field [0001] The invention relates to a lightning strike point testing technology for power transmission lines, in particular to a method for instantly and accurately determining the lightning strike point when a power transmission line is struck by lightning. Background technique [0002] With the vigorous development of my country's electric power industry, transmission lines of various voltage levels are constantly being built and completed. Power transmission line projects, especially ultra-high voltage and ultra-high voltage transmission line projects, are the lifeline projects of national economic construction and social development, and the tower structure in the transmission line bears the heavy responsibility of overhead power transmission lines. my country is a country with very strong thunder and lightning activities. In Guangdong and parts of Hainan, the annual average thunder and lightning days are as high as 120-130 days. Since the overhead power tra...
