System for gathering thunderbolt information

Abstract

A system for gathering thunderbolt information, which can be made of components with minitype and low price and circuit, and the system is simple, minitype, light, low price and has excellent property. In the system, the thunderbolt measuring device is provided with plurality of mechanisms for obtaining the thunderbolt information during thunderbolt time; the data gathering device has mechanism connect with each thunderbolt measuring device and mechanism for gathering data; the detecting winding is adjacent to conductor and disposed as the pose for making the winding toward the magnetic direction generated by the thunderbolt current flow into the conductor; the detecting winding is composed of two windings having same shape and wind number, and disposed as same pose and status of offsetting determined size opposite distance with conductor; the thunderbolt measuring device is equipped with: a mechanism for measuring charging voltage generated by two detecting windings; a mechanism for computing the distance between one of the detecting windings and the conductor by the ratio of the charging voltage; a mechanism for computing the thunderbolt current based on the distance and the charging voltage generated by one detecting winding.

Description

technical field [0001] The present invention relates to a system (device) for detecting lightning strikes and obtaining data, and more specifically, relates to carrying out the lightning strikes when there are lightning strikes on power supply equipment with power transmission and distribution iron towers, wires, etc., or related electrical equipment, etc. Detection and measurement of current (surge current, lightning strike current), a system (device) that can obtain information and data about lightning strikes. Background technique [0002] As a conventional lightning surge detection device, there is a device using a Rogovsky coil (Rogovsky Coil) as a current sensor. The effective value circuit takes out the waveform voltage of the lightning current, digitizes the waveform through a 100MHz high-speed AD conversion element, and stores it in the memory through CPU control. Through such processing, it is possible to measure the lightning current waveform (sometimes only the ...

AI Technical Summary

Problems solved by technology

[0009] As mentioned above, in conventional lightning current observation devices using Rogowski coils, etc., there is a problem that it is difficult to make a small, lightweight, and low-cost device, and it has to be a relatively large and expensive device.

Therefore, even if you want to set more lightning strike observation points, there is a problem that you cannot install enough devices in terms of cost.
