Further, the lightning protection device and magnetic saturation isolating transformer are electrically connected with.
Further, the fireprotection layer uses flameproof protection coating chlorinated rubber.
Further, the corrosion-resistant coating uses epoxy coating.
Compared with prior art, the utility model has the advantages that：A kind of light earthed system lightning protection device, passes through
It is that SPD rear ends increase a set of magnetic saturation isolating transformer in lightning protection device, so by protection equipment and may the power line with thunder and lightning
Between realize complete physical isolation, the security of equipment is improved, because magnetic saturation isolating transformer has good insulation
Isolation performance and voltage stabilizing so also reduce the requirement to grounding resistance, due to grounding resistance require it is low thus construction costs more
Low, the duration is shorter, due to magnetic saturation isolating transformer have it is good be dielectrically separated from performance and voltage regulation performance thus lightning protection properties more
