  III.Lightning protection and grounding technology features

  1,Excellent safety performance and resistance reduction effect;

  2,significant anti-corrosion factor and environmental protection characteristics;

  3,convenient use of steps and a wide range of applicability.


  IV.The application of lightning protection and grounding technology

The application of lightning protection and grounding technology

  1,alpine environment:flexible grounding technology for alpine rocky less land structure has strong applicability;

  2,narrow terrain:the site is small,the external lead is difficult to complete,and the grounding resistance requirements are very high;

  3,underwater environment:pumped storage power stations,water photovoltaic power stations,high mountain hydropower stations and other underwater grounding environment.


  V.Technical basis for lightning protection and grounding

Technical basis for lightning protection and grounding

  1,increase the effective contact area between the metal grounding electrode and the medium(rock,soil)-the most important factors

  Because the metal surface is smooth,and the soil is generally a small granular material,so the contact between them is a multi-point contact rather than surface contact,so there are too many ineffective area,rock is more so.

  2,reduce the resistivity of the medium(rock,soil)itself-the second major factor

  R=0.5ρ/√S can be seen to reduce the resistivity of the medium(soil replacement)can reduce the grounding resistance of the ground network.

  3,increase the water content of the medium-the third factor

  The resistivity of the same medium and the water content is usually inversely proportional to the higher the water content of the soil,the lower the resistivity.

  VI.The principle of lightning protection and grounding technology

  1,the idea:from the perspective of energy conversion,charge neutralisation,at the molecular level to analyse the nature of lightning current,fundamentally improve the grounding network shaping method,to build a safe and stable lightning discharge environment.

  2,Neutralisation:the number of free charge stored in the grounding network is expanded to dozens of times,thus increasing the charge neutralisation capacity of the grounding network,so that the grounding network has a good capacitance,which can achieve instantaneous neutralisation of the lightning charge,offsetting lightning overvoltage.

  3,impact:the use of new composite materials is conducive to the qualities of the charge through the formation of multi-dimensional universal discharge channel within the grounding network,the level of impact resistance for the grounding network to achieve a crucial enhancement.


  Ⅶ,Lightning protection and grounding technology qualities

  1,flexible:the use of liquid pouring,solid gel-like moulding of the new construction process,maximize the effective contact area between the metal grounding electrode and the rocky soil,in order to achieve the effect of reducing the grounding resistance.

  2,water retention:the use of new composite materials in the full,not easy to lose the water molecules,so that the grounding network is not affected by the moisture content of the surrounding soil,even in the dry season can also maintain a very low grounding resistance resistance value.

  3,anti-corrosion:the new grounding network forming methods and materials within the anti-corrosion factor makes the metal grounding electrode to obtain isolation of acid and alkali,isolation of oxygen protection,strengthening the corrosion resistance of the grounding network,to extend the service life.
