Problems solved by technology
[0041] The main purpose of the present invention is to provide a lightning current energy detection method, which aims to solve the problem that in the current lightning current detection method, the method of accurately describing the real-time waveform of the lightning current requires sophisticated instruments, high cost and very good shielding Measures, it is difficult to implement in the user terminal, and only detect the peak value of the lightning current, while ignoring or defaulting the waveform function of the lightning current is too simplified, and sometimes it cannot even reflect the energy of the lightning current at all.

Embodiment Construction
[0067] In order to make the purpose, principle and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0068] In the present invention, the lightning current energy is shunted and stored in a fixed proportion through the charge storage device, and then the stored energy is detected, and finally these energies are equivalently converted into the lightning current standard waveform function and its peak.
[0069] figure 2 The implementation flow of the lightning current energy detection method provided by the embodiment of the present invention is shown. For the convenience of description, only the parts related to the present invention are shown, and the details are as follows.
[0070] The present invent...

The invention relates to a lightning current energy detection method, system and lightning protection equipment. The method includes the following steps: sampling the lightning current introduced into the propagation path, the sampling current is in a fixed ratio to the lightning current; rectifying the sampling current; storing the charge of the rectified sampling current, and the stored total charge is equal to The total charge of the lightning current is directly proportional; the voltage value of the stored total charge is detected, the total charge of the lightning current is calculated, and normalized to the total charge of the standard waveform function of the lightning current, and the corresponding lightning current is calculated. The peak value of the lightning current of the current standard waveform function. In the present invention, the lightning current energy is used as the detection basis instead of the lightning current peak value as the detection basis. Because the destructive ability of lightning current is proportional to its energy and not to its peak value, the uncontrollable error caused by the method based on the peak value of lightning current is corrected, which can more truly reflect the damage of lightning current ability.
Description
technical field [0001] The invention relates to the technical field of lightning current detection, in particular to a lightning current energy detection method, device and lightning protection equipment. Background technique [0002] Lightning disaster is one of the ten most serious natural disasters announced internationally. Every year, lightning disasters occur frequently and involve a wide range of areas, posing a serious threat to the lives and property of the general public. [0003] At the same time, people's research on lightning is constantly deepening, and the definition and measurement of lightning current can be said to be the cornerstone of all research on lightning, which shows its importance. [0004] But lightning in nature is intricate, and almost every lightning strike has a different form. Even people can't find a unique waveform function to characterize all lightning strikes through a large amount of data analysis. In order to facilitate quantitative ...
