The down lead shall be electrically connected up and down, and the impulse grounding resistance value of each down lead shall not be greater than 10 & omega;, And make reliable electrical connection with the grounding body (Network)
The average distance between down conductors shall not be greater than 18m It is advisable to use the two main reinforcements in the diagonal inside the structural column outside the building as the lightning protection grounding down lead
The down lead shall be electrically connected up and down, and the grounding resistance value of each down lead shall not be greater than 10 & omega;, And make reliable electrical connection with the grounding body (Network)
The average distance between down conductors shall not be greater than 25m Grounding device , The reinforcement mesh in the building foundation should be preferentially used as the grounding body
When the grounding resistance value of the grounding body cannot meet the requirements, an artificial grounding body should be added Technical description of lightning rod tower: , Foundation description of triangular lightning Tower: 1
The diameter of nine anchor bolts is 24mm 2
The anchor bolt shall be 100-150mm above the concrete level 3
Grounding Foundation: 2m wide, 2m long and 2m deep 4
The diameter of nine anchor bolts is 24mm 5
The anchor bolt shall be 100-150mm above the concrete level 6
Grounding Foundation: 2m wide, 2m long and 2m deep (1) Advance discharge lightning rod wjz3 3   Working principle , WJZ series lightning rod is made of foreign * * * technology and process * * *, which has won the national * * *
The exciter mainly absorbs and stores energy from the electric field in nature
The tip of reflector and lightning arrester is well electrically connected with the earth and is in equipotential state
Therefore, generally, there is an electric field strength between the exciter and the transmitter
Before lightning flash, the electric field strength will increase rapidly
The potential difference between the exciter and the reactor is roughly equivalent to the potential between the thunder cloud and the earth
The rapid increase of voltage drop between them will cause * * * fire, ionize the air around * * * and form * * * discharge phenomenon The electric field between the central collecting rod of the lightning rod and the exciter exciters increases rapidly, resulting in the air ionization generated by * * * can be discharged in a very short and accurate time
Due to the existence of a large number of electric ions, the natural corona effect is reduced and an expected upward discharge channel is generated, which can intercept lightning and safely discharge to the earth quickly and safely

Lightning pin protection range France * * * nfc17-102 stipulates that when the tip of ese (PDA) needle is 2m, 3M, 4m, 5m, 6m, 7m, 10m and 20m higher than the protected object, the protection range is related to the early discharge time △ t of the needle, the needle height and the lightning protection category of the building: RX = & Radio; H(2Hr-H)-√ Hx(2Hr-Hx)  Where: is the protection radius of the horizontal plane (ground) (m) H is the height difference of needles relative to the exhibition surface of the protected object (m) D is the rolling ball radius: ,*** 30m for class I Lightning Protection Buildings ,*** 45m for class I Lightning Protection Buildings The third type of lightning protection building is 60m △ L is the height of upward lightning receiving, △ L = △ T & times; v  △ t advance discharge time, 25 & Mu respectively; s、 35μ s、45μ s、60μ s  V=1m/μ S (pilot speed), i

△ L is 25, 35, 45 and 60m respectively
Therefore, different models & omega- The protection radius of x-needle to the protected object is different at different heights For details, please contact Xue Hong 18503833715 of Zhengzhou Wanjia lightning protection Co
