Description
Technical field
The invention belongs to power overhead network technical field, and in particular to a kind of insulated overhead line with electrical verification rod
High-tension insulator.
Background technology
Overhead line can produce power frequency continued flow after being struck by lightning, so-called power frequency continued flow, be exactly overhead line after overhead line is struck by lightning
Thunder and lightning arc is just produced between metal cross arm, this thunder and lightning arc life span is very short, but it is formd between overhead line and cross-arm
Conductive channel, the power supply of overhead line is set to occur over the ground（Cross-arm）Short circuit, this short circuit current are referred to as power frequency continued flow（Be after lightning current it
Power current afterwards）, for power frequency continued flow, cross-arm or grounding of pole resistance are bigger, and power frequency continued flow is smaller, easier cutout.
Patent document CN201000796Y discloses a kind of lightning protection pillar insulator, is mainly closed by insulating shield, clamp aluminium
Gold utensil, composite insulator, starting rod and lower steel pin etc. form.Its main feature：（1）When thunderbolt occurs, starting rod and lower steel
Causing umbrella network to discharge between pin, form short-channel, the power frequency arc to continue, which is moved between starting rod and lower steel pin, to burn, with
Protect wire from burn.Because starting rod gets around full skirt and adjusts to optimal discharge gap, discharge effect is more preferable, and prevents from burning out
Insulator umbrella.But this kind of lightning protection pillar insulator still suffers from following weak point：Outside the point of discharge of starting rod and lower steel pin
Dew, easily accumulates dirt, influences discharging action.
In addition, existing insulated overhead line in maintenance, it is necessary to set up electricity testing rod, be applied not only to judge circuit whether band
Electricity, ground wire can be also accessed to reduce electric shock risk；But existing insulated overhead line whole body insulation, traditional electricity testing rod
Can not directly it use；Therefore also need to be improved some existing insulators, it can arrange in pairs or groups and use with existing electricity testing rod.
The content of the invention
The present invention provides a kind of high-tension insulator of insulated overhead line with electrical verification rod built in discharging gap.
Realizing the technical scheme of the object of the invention is：A kind of high-tension insulator of the insulated overhead line with electrical verification rod,
Including the insulation shell with cavity, upper contact rod, be used for and upper contact rod formed discharging gap lower contact rod and one
With the electrical verification rod of upper contact rod electrical connection.
In such scheme, upper contact rod and lower contact rod are located along the same line, and discharging gap is located in cavity.
In such scheme, the top of the bottom of upper contact rod and lower contact rod is respectively provided with a ball discharge, this two electric discharges
Ball chuck closes to form discharging gap.
The present invention has advantages below：（1）The upper contact rod of formation discharging gap and lower contact rod are placed in insulator
In cavity, it is ensured that the cleaning of point of discharge, so as to ensure that the reliability of discharge prevention action；（2）Electrical verification rod is arranged to
Electrically connect with upper contact rod, used so that it can be mounted with existing electricity testing rod.
