302, composition the air gap, the gap electric discharge of upper electrode and bottom electrode, fixing on described wire
Being provided with puncture gold utensil 4, described puncture gold utensil 4 is made up of upper and lower part, upper and lower part
One end chain connection, the other end is bolted, and centre has the portion of piercing through and is stuck on wire 1；
The bottom electrode 302 of described insulator 3 lower end connects on puncture gold utensil 4 by wire, described
Upper electrode and bottom electrode be hot-galvanized steel or aluminum alloy materials, upper electrode and bottom electrode air
The distance in gap is 17-19, and lightning arrester body is zero-clearance zinc oxide lightning arrester；Employing keeps away
Thunder device lower end installs insulator additional, and insulator two ends install electrode additional and bottom electrode constitutes the air gap
Electric discharge, anti-lightning strike broken string gap discharge realizes energy conversion and avoids wire to be struck off, with low cost,
Easy construction, flexibly, has stronger mechanical performance；Also have in lightning arrester body electric discharge external
Lightning arrester body damage in the case of electric arc arc root by wire transfer to puncture armour clamp assembly continue
The arc root of power frequency short circuiting arc be fixed on puncture armour clamp assembly the still protection wire that burns and exempt from
In burn broken string.
Of the present utility model ultimate principle, principal character and this practicality are more than shown and described new
The advantage of type.Skilled person will appreciate that of the industry, this utility model is not by above-described embodiment
Restriction, principle of the present utility model is simply described described in above-described embodiment and description,
