Lei Yi enemy of France over 40 years of mine   production and mine-browser experience and a strong work by Frances most famous   universities and research institutions team of engineers to INDELEC ( "easy to   mine enemies") become a lightning protection device lightning protection   equipment expert. Both in France and elsewhere in the world, PREVECTRON mine   unstoppable After decades of success, INDELEC (easy enemy mine) is the full   launch of its latest research results: uPREVECTRON (second generation) lightning.   (Hereinafter referred to PREVECTRON 2)  
           
Lei Yi INDELEC enemy action   is how a lightning rod  
When the thunderstorm came, and the energy is huge   (to several thousands of volts per Mida), PREVECTRON 2 early pre-discharge   lightning protection air terminal device of the electric field from the natural   world to absorb energy, the bottom electrode to collect the energy stored in the   electric energy lightning protection device trigger device. Every time prior to   the occurrence of lightning, field strength will be rapidly increased, the   storage device when the mine reached a certain level of energy, air terminals   will be placed on information delivery to the mine electrical trigger device,   the cutting-edge in the air terminal will have a spark, and so that the air   around the plasma edge, and the formation of point discharge phenomenon.  
 
Lei Yi INDELEC enemy principle of early pre-discharge lightning rod  
 
In the air terminal tip of the ion can be characterized as follows:   control of ion release: PREVECTRON 2 early pre-discharge lightning protection   devices to allow devices to trigger the plasma in a very short period of time   discharge lightning protection device trigger system means that the extreme   accuracy ion can be in a very accurate time was released, in other words, in the   main of the twinkling of an eye prior to the occurrence of lightning. CORONA   trigger effect: the existence of a large number of initial electrons, together   with the rapidly increasing electric field the effect of natural CORONA reduced   trigger. The discharge channel is expected to be cited: PREVETRON 2 pre-early   discharge from the lightning rod tip is designed to produce a discharge passage   quoted above is expected, and earlier than those who have a nearby high point,   which indicated that the early pre-discharge PREVECTRON 2 become a lightning rod   in its protection the scope of the most influential point. Measured in the   laboratory, this time ahead of the trigger time is defined as △ T, represent the   comparison with a single rod, PREVECTRON 2 early pre-discharge lightning rod   measuring the effectiveness of air terminals better.

Early pre-PREVECRON 2 a total of   five models of lightning discharge. Each model in which the central collection   of stainless steel rod, electrode composition and boxes suitable for corrosive   environment, corresponding to the different radius of lightning protection, each   model, respect  
 
ively, with their different performance characteristics.  
     
  Lightning   discharge in advance the advantages INDELEC  
  With a wide variety of lightning   protection radius for different models to choose  
  More effective  
  Fully   active lightning protection system  
  Omen only when there is lightning when   lightning protection device self-activation  
  Permanent connection with the   earth, can enhance the safety of lightning protection systems  
  Fully reliable, after by the CNRS (French   National Center for Scientific Research) in the high-voltage laboratory testing   and by the CEA (French Atomic Energy Commission) carried out under the   conditions in the real lightning test standards in line with the French National   Lightning.

  Early   pre-discharge PREVECTRON 2 mines air terminal from the following   components: 
   
      
   
  Lightning INDELEC   Model: TS2.10, TS2.25, TS3.40, S2.25, S3.40, S4.50, S6.60 active lightning,   lightning prone mine enemy, mine enemy mine easily, and early pre-discharge   lightning, lightning discharge in advance, the British Deli lightning.  
  INDELEC lightning calculation of protected areas  
   
  Active anti-Fu   PREVECTRON2s protection radius Rp mine from the French national standard NF   C17-1O2 by the formula given by:  
  RP=  (h <= 5)  
  The above formula applies to the installation of a lightning rod   height h> 5m; when h <5m, by Table 1.1 to identify each type of mine the   corresponding radius of the lightning protection.  
  Of which:  
  ① h for the   mine to the browser at the top of the actual plane was a high degree of   protection.  
  ② D distance or bowls for the shock radius, which depend on the   level of protection the protection of objects. For Class 1, Ⅱ type, Ⅲ type of   lightning protection level, D value of 20 meters, 45 meters, 60 meters.   Protected material to determine the level of lightning protection lightning   protection standards see the French NF Cl7-102 standard Appendix.  
  ③ △ L (m)   = 1 (m / μs) × △ T (μs). △ T is the leading time in advance of its actual value   measured by high-pressure experiments showed that in Table 1.2 are given for   each value of △ T models.
