Explosion proof lightning detection and early warning system in Sinopec tank farm passive lightning protection and early warning device in port area

  Explosion proof lightning detection and early warning system in Sinopec tank farm passive lightning protection and early warning device in port area , Lightning is a long-distance discharge phenomenon with instantaneous high current, high voltage and strong electromagnetic radiation in the atmosphere
With the increasing loss of personnel and property and social impact caused by lightning, the demand for lightning monitoring and early warning is becoming more and more urgent
At present, the monitoring and early warning of lightning is well realized by using the electrical, magnetic and optical characteristics of lightning and related equipment
Lightning is monitored through relevant equipment
When selecting and planning facilities such as power, communication, railway and construction, try to avoid areas with frequent lightning activities, or strengthen the lightning protection level of facilities
At the same time, it also provides many services for lightning disaster physical monitoring and lightning weather research
Early warning of lightning through relevant equipment can not only make personnel in outdoor places avoid in advance and remind field operators to suspend outdoor operation and lightning protection in the house, but also timely take appropriate measures for flammable and explosive places, such as suspending outdoor refueling operation in gas stations to prevent major lightning disasters
Lightning monitoring and early warning equipment is widely used in many fields, such as meteorology, aviation, aerospace, communication, electric power, tourism, forestry, construction and so on

  The functions of lightning detection and early warning system are as follows:
(1) Provide a scientific basis for the formulation of safety and stability management system to ensure personal safety and stability

(2) Switch the power supply in advance, disconnect the mains power, prevent lightning stroke, protect data and ensure the safety and stability of the equipment

(3) Close the equipment that can be closed temporarily before lightning strike to avoid economic losses

  The lightning detection and early warning system can directly detect the atmospheric electric field data with the measuring station as the center and the radius of 15 ~ 83km
The early warning time is 10 to 30 minutes
The atmospheric electric field instrument can better warn whether lightning will occur
When combined with lightning locator and meteorological radar to monitor the moving trend of lightning, it can more accurately warn lightning
There are also deficiencies in the atmospheric electric field instrument: the early warning area of a single station of the electric field instrument is limited; The detected electric field is vulnerable to external signals and has a certain false alarm rate; The detected atmospheric electric field is the result of the superposition of electric fields in different directions and has no directionality
