| Abstract: | In order to solve the new contradiction and questions about lightning strike breakdown,insulation coordination,equipment selection,construction technology caused by overhead line distribution net newly built using the insulated conductor and old line insulation transformation,the article analyses thoroughly mechanism on lightning strike breakdown and corrosion wire breakage.Contrasts the advantage and disadvantage of the method presently adopted and the suitable situation,overvoltage protector is proposed on the base of lines situation.Meanwhile how to choose the overvoltage protector equipment and how the equipment parameter is determined is discussed in detail and the relevant technical measure is proposed. |
