Abstract

The invention provides a lightning overvoltage measuring system, which comprises a lightning overvoltage sensor, a high-speed data acquiring and processing unit and a solar power supply system, wherein the lightning overvoltage sensor is realized by adopting a high-speed capacitive voltage divider, and can be used for acquiring instantaneous voltage during lightning overvoltage through the operation of the high-speed capacitive voltage divider; the high-speed data acquiring and processing unit is used for acquiring a low-voltage signal from the lightning overvoltage sensor; the low-voltage signal is firstly subjected to analog-digital conversion through an analog-digital converter, and is buffered in a buffer; a processor is used for reading data in the buffer for processing. The solar power supply system can be used for providing energy for the lightning overvoltage measuring system without connecting a general alternating-current power grid power supply, and the influence of measuring high voltage generated by lightning on an alternating-current power grid is avoided.

Description

Technical field [0001] The invention relates to the technical field of lightning monitoring, in particular to a lightning overvoltage measurement system. Background technique [0002] According to incomplete statistics, lightning strikes cause 3,000 to 4,000 casualties each year in my country, and property losses reach a staggering 20 billion yuan. Lightning disasters have become one of the increasingly destructive meteorological disasters. The electromagnetic transient phenomenon caused by lightning belongs to the scope of electromagnetic pollution, and electromagnetic pollution is recognized as the fourth largest pollution in the world after water pollution, air pollution and noise pollution. With the modernization of industrial and agricultural production and people’s lives, the requirements for the reliability and service quality of service systems and facilities such as railways, aviation, finance, electricity, telecommunications, television, and networks have become higher ...
