Description
Technical field
The utility model belongs to power overhead network technical field, and in particular to a kind of aerial insulated wire with electrical verification stick
The high-tension insulator on road.
Background technology
Overhead line will produce power frequency continued flow after being struck by lightning, so-called power frequency continued flow is exactly overhead line after overhead line is struck by lightning
Thunder and lightning arc is just generated 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 makes the power supply of overhead line occur over the ground（Cross-arm）Short circuit, this short circuit current are known 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
The compositions such as gold utensil, composite insulator, starting rod and lower steel feet.Its main feature：（1）When lightning stroke occurs, starting rod and lower steel
Causing umbrella network to discharge between foot, forms short-channel, the power frequency arc of connecting, which is moved between starting rod and lower steel feet, to burn, with
Protect conducting wire from burn.Because starting rod gets around full skirt and is adjusted to optimal discharge gap, discharge effect is more preferable, and prevents from burning out
Insulator umbrella.But there are still following shortcomings for this kind of lightning protection pillar insulator：Outside starting rod and the point of discharge of lower steel feet
Dew is easy accumulation dirt, influences discharging action.
In addition, existing insulated overhead line in maintenance, needs to set up electricity testing rod, be applied not only to judge circuit whether band
Electricity can also be accessed ground wire to reduce electric shock risk；But existing insulated overhead line whole body insulation, traditional electricity testing rod
It can not directly use；Therefore also need to be improved some existing insulators, it can arrange in pairs or groups and use with existing electricity testing rod.
Utility model content
The utility model provides a kind of high-voltage isulation the insulated overhead line with electrical verification stick built in discharging gap
Son.
Realizing the technical solution of the utility model aim is：A kind of high-voltage isulation of the insulated overhead line with electrical verification stick
Son includes insulation shell with cavity, upper conductive rod, be used for and upper conductive rod forms the lower conductive rod and one of discharging gap
The electrical verification stick of a and upper conductive rod electrical connection.
The utility model has the following advantages：（1）The upper conductive rod of formation discharging gap and lower conductive rod are placed in insulation
In the cavity of son, it is ensured that the cleaning of point of discharge, to ensure that the reliability of discharge prevention action；（2）Electrical verification stick is set
It is set to and upper conductive rod is electrically connected, used to allow itself and existing electricity testing rod to mount.

Specific implementation mode
（Embodiment 1, lightning protection pillar insulator）
In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, below in conjunction with attached drawing
And specific embodiment is described in detail.
The utility model provides a kind of high-tension insulator of the insulated overhead line with electrical verification stick, such as Fig. 1 and Fig. 2 institutes
Show, include insulation shell 1 with cavity 11, be arranged on insulation shell top be used for and the clamp of aerial cable electrical connection
Gold utensil 2 and clamp gold utensil electrical connection upper conductive rod 3 and be used for and upper conductive rod formed discharging gap lower conductive rod 4.
The bottom end of upper conductive rod and the top of lower conductive rod are respectively provided with a ball discharge 5, which is located at
The upper and lower part of the cavity, discharging gap are located at the middle part of cavity.
When lightning stroke occurs, thunder-strike current discharges between two ball discharges.
The upper and lower ends of insulation shell are respectively provided with a metal cover 12, and each metal cover is fixed at phase by rolling mode
On the one end answered；Through-hole 121 is equipped at the center of each metal cover, upper conductive rod and lower conductive rod are fixedly installed by welding manner
In a corresponding through-hole.
Insulation shell is made of ceramics, and the middle part of insulation shell is equipped with column porcelain tripe 13, and the periphery wall of porcelain tripe is equipped with
The cyclic annular full skirt 14 of evagination, the wall body of porcelain tripe are equipped with the bleeder port 15 of a plurality of connection cavity；When thunder-strike current discharges, cavity
Interior when gases are heated, they expand, is discharged from bleeder port.
Corresponding metal cover and the electrical connection of clamp gold utensil are stretched out in the upper end of upper conductive rod upwards as power connection end 31.
Further include an electrical verification stick 6, the power connection end 31 is equipped with radially installed hole 32, and the middle-end of electrical verification stick is fixed at
In radially installed hole, to be electrically connected with power connection end；The both ends of electrical verification stick 6 are then stretched out towards the both sides of upper conductive rod respectively.
In the present embodiment, the middle-end of electrical verification stick 6 is fixed at by welding manner in the radially installed hole of upper conductive rod,
The middle-end of electrical verification stick is radially extended along upper conductive rod, and the both ends of electrical verification stick are also upturned to form anti-delinking part 61.
The lower end of lower conductive rod extends downwardly corresponding metal cover as the mounting portion 41 being fixed on cross-arm.
The upper conductive rod and lower conductive rod are located along the same line.
Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to the embodiment of the utility model.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
It is exhaustive.And the obvious changes or variations that these connotations for belonging to the utility model are extended out still fall within this practicality
Novel protection domain.
