France INDELEC enemy lightning rod Yi Lei SPD Introduction

France INDELEC radius of the table lightning protection

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.

Celletti enemy easy product line before the lightning discharge
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.

Active INDELEC profile lightning rod product mix
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.
