A kind of rural power grids 10kV lightning protection suspended compound insulators, including plug, umbrella cover, gold utensil cap, upper arcing horn, lower arcing horn
And electricity testing grounding ring；Umbrella cover is fitted on plug, is solidified as a whole with plug；Distinguish crimping armor clamp cap and gold utensil at plug two ends
Pin；Upper arcing horn is arranged on gold utensil cap, and lower arcing horn and electricity testing grounding ring are arranged on gold utensil pin in combination；Upper arcing horn and
Lower arcing horn curves inwardly, and manifold type is relative, and its upper end is equipped with discharging gap；Upper arcing horn and lower arcing horn phase on plug
It is dielectrically separated from.
Umbrella cover uses high temperature vulcanized silastic material.
The hollow intraoral of gold utensil cap is provided with gold utensil pin.
Upper arcing horn, lower arcing horn and electricity testing grounding ring outer layer are surrounded by high-temperature silicon disulfide rubber.
The utility model has the advantage of：In normal state, the discharging gap for being formed between upper and lower arcing horn is failure to actuate；Only
When occurring the lightning surge more than design code value, the gap between upper and lower arcing horn could be breakdown, forms short-channel.
The power frequency arc for continuing just burns on the striking fork of wire clamp, discharges overvoltage energy, to protect wire from burn.
Meanwhile, arcing horn outsourcing high-temperature silicon disulfide rubber, blocking electric arc is along arcing horn surface to insulator and lead body
The passage for moving about, so that it is guaranteed that it has stable and reliable lightning protection properties.
In addition, the electricity testing grounding ring of outsourcing high-temperature silicon disulfide rubber, dielectric level is high, during maintenance construction, can be easily
Carry out electrical verification or temporary grounding.Dependable performance, can greatly mitigate the labour intensity of operator.The utility model rural power grids 10kV
Lightning protection suspended compound insulator, lightning protection properties are reliable and stable, and rationally, feasible process is that is, economical and practical for product structure.
