ESE Early Discharge Stainless Steel Lightning Rod OEM ODM Service

ESE Early Discharge "HDE" Lightning RodThe workflow of "HDE" lightning rod

The formation of thunderclouds prompted the formation of electromagnetic fields between the ground and the clouds, the magnetic field strength of the ground can exceed 14KV / M.

a) At this time, the lightning rod detector discharge in advance, will detect a certain electromagnetic signal

b) then, the detected lightning signal transmitted by the sensor to the trigger device

c) trigger device will signal amplification, prompting the next level of high-voltage generator action

d) The high voltage generator will transmit the generated high voltage to the high voltage pulse generator

e) The high voltage pulse generator transmits the ions generated by the high voltage oscillation directly to the stainless steel electrode

f) the ions at the tip of the stainless steel electrode are effectively transmitted to the tip of the lightning rod through the venturi.

Early discharge lightning rod has two actions.

Action one: the use of thundercloud electric field, trigger device in the tip of the needle to generate high-voltage pulse, the formation of corona discharge.

Action two: the pulling action through the venturi tube, so that the electric ion more powerfully to the tip of the needle. The upward pilot generated by the pulse will shorten the rendezvous time with the downward pilot.

The technical characteristics and advantages of "HDE".

(1), in the same height, "HDE" than the ordinary lightning rod protection range is larger.

(2), because the convergence point of the upstream lead wire and downstream lead wire is far from the tip of the needle, so it can effectively reduce the amplitude of the lightning strike current.

(3), the dual role of falling lightning is more accurate, reducing the probability of lightning strike point falling on non-lightning rod.

Action one: the use of thundercloud electric field, the trigger device to generate high-voltage pulse on the tip of the needle, the formation of corona discharge.

Action two. Wen's tube design: through the pulling effect of Wen's tube, so that more electric ions, to reach the tip of the needle, as opposed to HDE lightning rod without this structural design, "HDE" can be more **** trigger corona effect.

(4), safe and reliable: non-radioactive, corrosion-resistant; strong wind resistance (wind up to 45m / s).

(5), easy to install: small size, light weight, easy to install; no need to add coaxial shield wire.

(6), maintenance-free: passive, no energy-consuming components, no need for power supply.

(7), beautiful shape: made of high-quality 304 stainless steel material precision processing, material and structure are in line with the requirements of the national standard GB50057-2010 (corrosion resistance, demining channel for good conductor).

(8), in line with the French national standard NFC17-102, obtained ISO9001 quality certification, through the MASE safety certification.

Calculation of the protection range.

8.1 Determine the protection range of the HDE according to the "rolling ball method" recommended by IEC (see Appendix A for training materials).

8.2 Calculation formula of the protection range

(1), when the tip height Z ∈ [5,x] m.

r = √ (x + y) 2-(x - z)2

(2) , when the tip height Z ∈ [0,5] m.

r = √ (x + y)2 - (x - 5)2 × z ÷ 5

R --- radius of protection

X --- ball rolling radius X ∈ {20,30,45,60,100}.

Y --- preemptive strike distance Y ∈ {25,40,50,60}.

Z --- the height of the tip of the needle Z∈[0,x]

"HDE" design instructions.

The installation of "HDE" lightning rod in China must strictly comply with the mandatory provisions of the National Standard of the People's Republic of China - "Lightning Protection Design Code for Buildings" (GB50057-2010).1.

1. the installation of "HDE" lightning rod in China must strictly comply with the national standards of the People's Republic of China - "lightning protection design code for buildings" (GB50057-2010) mandatory provisions.

2. According to the area of the protected building, height, the number of lightning days and geographic environment correction factor, the nature of building use to determine the building lightning protection category.

3. According to the lightning protection category and the area of the building, choose one or several "satellite" lightning rod.

4. The fuse should be connected to the main electrical of the steel building, or two or more fuses as needed to select two suitable fuses.

5. The fuse should be disconnected from the card and in the vicinity of the ground for insulation protection.

6. The grounding body and grounding resistance should meet the requirements of GB50057-2010.
