Solar street lights to how to protect against lightning strikes

Summer is the season of frequent thunderstorms, for outdoor solar street lights, it is very necessary to set up lightning protection, because of its height, etc. It is easy to be attacked by electric lightning, solar street lights lightning strike mainly has four types: switch overvoltage, should be lightning, conductive lightning, direct lightning. So solar street lights to how to prevent lightning strikes? For this problem, the next amber lighting for everyone to introduce.
First, the pole body to receive flash
In order to prevent lightning from directly hitting the solar street lamp pole, the pole needs to be made into a flash catcher, so that when lightning strikes can directly lead the lightning to itself, to undertake direct lightning discharge.
Second, electrical grounding
1. Protective grounding
In order to prevent equipment leakage when endangering the safety of personal and equipment, all electrical equipment exposed conductive parts through the grounding wire grounding resistance should be in line with the leakage protector installation action requirements.
2. Working grounding
Directly ground the neutral point of low-voltage power grid, the system grounding resistance should be less than 10Ω.
3. Lightning grounding
In order to prevent electrical equipment from lightning strikes, the lightning rod, lightning wire and lightning arrester and other lightning protection devices for grounding, grounding resistance should be less than 10Ω.
Three, metal zeroing
The metal shell of electrical equipment, metal frame, etc. and neutral ground connection. Grounding wire should be used insulated wire, and use the whole line, no joints in the middle. Lightning arrester grounding line should be selected to the short distance to the grounding line. Protection device phase line cross-sectional area of S ≤ 16mm2, grounding wire and protection line small cross-sectional area of S, 16 ≤ 35 grounding wire and protection line small cross-sectional area of 16, S > 35 grounding wire and protection line small cross-sectional area of S / 2, grounding wire welding length flat steel ≥ 2 times the width of the flat steel.
Fourth, the circuit protection
Installation of special solar lightning protector, according to the solar street lamp power supply voltage design, lightning weather, the solar street lamp circuit will be generated by electrostatic induction or electromagnetic induction of a sudden peak voltage or sudden peak current through, affecting the LED solar street lamp equipment. Solar street light special lightning protector is to protect the power line surge voltage, can avoid the same area of solar street lights lightning damage phenomenon.
The above on solar street lights how to protect against lightning strikes for you to share here, in short, in the season of frequent thunderstorms, solar street lights lightning protection work must be done in advance, in accordance with the above method of operation, can effectively avoid solar street lights in the case of lightning strikes caused by unnecessary harm.
