Problems solved by technology

The structure of the above method is simple, but when designing the Rogowski coil, the linear relationship must be considered, especially when the lightning current is directly measured, the insulation withstand voltage problem must also be considered. When there is a magnetic ring in the Rogowski coil, the magnetic core insulation problem must also be considered. To a large extent, the development of this method is limited

Abstract

The invention discloses a device for measuring a lightning current parameter by using an optical fiber. The device comprises an optical transmission module, an optical sensing module, an optical receiving module and a signal processing module. According to the device, a Faraday magneto-optical effect principle is utilized, the optical fiber is taken as a medium, and the magnitude of measured current is calculated reversely by measuring the rotation angle of the polarized plane of light waves passing through a magneto-optic material under the action of the a lightning current magnetic field. The device has high sensitivity and interference resistance, can be arranged on a lightning arrester for monitoring lightning current data, is used for counting and analyzing data of lightning current, and is suitable for measuring lightning current generated by a lightning current simulative generator.

Description

technical field [0001] The invention relates to a device for measuring lightning current parameters by using an optical fiber, which belongs to the field of lightning science and technology. Background technique [0002] Thunder and lightning is a rapid natural discharge phenomenon that occurs between the clouds and the ground. The discharge process will release huge energy, resulting in dazzling lightning, thunder and powerful electromagnetic pulses. Lightning not only seriously threatens the safety of human life, but also has a huge impact on aviation, traffic, electricity, and construction, resulting in direct and indirect economic losses. Therefore, the generation and formation mechanism of lightning and lightning protection work have always been an important research content, and the monitoring of lightning current plays an important role in lightning protection technology. [0003] Lightning research scholars at home and abroad have achieved certain results by monitor...
