Sinopec oil depot lightning protection thunderstorm early warning system unattended lightning arrival prediction system

  Sinopec oil depot lightning protection and thunderstorm early warning system unattended lightning arrival prediction system has made remarkable development in the past few decades, including the technical system of real-time monitoring of atmospheric electrical activities and lightning in nature
These technical systems can provide high-quality and valuable thunderstorm occurrence information in real time, and provide a very important reference for people to use this information for various applications

  Although this information allows users to take emergency measures in advance, according to relevant regulations, the users are responsible for the preventive measures taken based on the monitoring information
The effectiveness of these measures largely depends on the size of the risk and the measures themselves
This standard gives a list of possible preventive measures Like many natural phenomena, lightning and thunderstorms have statistical uncertainties
Therefore, it is not possible to accurately obtain the time and location information of lightning in the future Other lightning protection standards do not cover the use of thunderstorm early warning system According to the detectable phenomena, the life cycle of thunderstorm includes four different stages: a initial stage, initial stage; B
growth stage; C) mature stage; D dissipation stage
The thunderstorm detector shall be classified according to the thunderstorm stage it can detect, and the thunderstorm stage is determined by the thunderstorm phenomenon that can be detected at this stage
Nevertheless, a thunderstorm detector can detect one or more thunderstorm phenomena
Generally, there are several ways to judge the method of thunderstorm detection by thunderstorm detector, especially lightning stroke
One is to check the thunderstorm stage that the detector can detect; The other is to compare the frequency band of lightning electromagnetic radiation with the electromagnetic frequency band that can be detected by the sensor; The third is to view the technology that the sensor detects lightning stroke and calculates its position
Thunderstorm or lightning detector is classified as follows: Class A: detect the whole life cycle of thunderstorm stage 1 to stage 4; Class B: detect cloud flash and ground flash from thunderstorm stage to stage 2 and 4; Class C: only ground flashes from thunderstorm stage 3 to stage 4 are detected; Class D: detection of lightning and other electromagnetic sources in Thunderstorm stage 3, with very low detection efficiency Consult Xue Hong 18503833715 of Zhengzhou Wanjia lightning protection for details
