In above-mentioned reason, the third is led in the building electric discharge of Line To Line row of channels both sides, current industry and not yet forms one
Plant ripe effective safeguard procedures.As urbanization process is accelerated, transmission line of electricity is in the design phase to building near line row of channels
If planning is difficult to control completely.Circuit was run after a period of time, it sometimes appear that new windage yaw hidden danger building, and these windage yaw are hidden
Suffer from building and often relate to multi-party interests, processing procedure is difficult, the probability that result in the generation of windage yaw discharge accident rises, harm
Safety and the people's lives and property safety of transmission facility.
The content of the invention
The harm of transmission line of electricity is directed to there is provided a kind of new instant invention overcomes above-mentioned existing windage yaw discharge accident
The overhead transmission line protector and system of windage yaw, can reduce the windage yaw discharge for leading the building electric discharge of Line To Line row of channels both sides
Accident, ensures the safety and the people's lives and property safety of transmission facility, reduces the generation of tripping fault.
In order to solve the above technical problems, technical scheme is as follows：
A kind of overhead transmission line protector for windage yaw, including insulating bar and some insulators, the insulator are conllinear
Set and one end of each insulator is fixedly connected with wall, the other end of each insulator is connected with insulating bar, and the insulating bar is also
It is parallel with exterior wall.
A kind of overhead transmission line guard system for windage yaw, including some overhead transmission lines for windage yaw are protected
Device, it is respectively parallel to each other for the insulating bar of the overhead transmission line protector of windage yaw.
In a kind of preferred scheme, described insulator is vertically set on exterior wall.
In a kind of preferred scheme, one end of described insulator includes cross-arm bearing, and the other end of insulator includes
Clamp steel cap, described cross-arm bearing is fixedly connected with exterior wall, and described clamp steel cap is fixed with insulating bar.Clamp steel cap is used for
Insulating bar is socketed, fixation is played.
In a kind of preferred scheme, the central point of described overhead transmission line protector is when generation maximum wind power
When the minimum hidden danger point of exterior wall and conductor spacing.Such setting at utmost protection equipment from the influence of wind-force, can drop
Low failure risk.
In a kind of preferred scheme, the distance between described insulating bar and insulating bar are identicals.
Compared with prior art, the beneficial effect of technical solution of the present invention is：New wind is directed to the invention provides a kind of
Inclined overhead transmission line protector and system, can reduce the windage yaw discharge thing for leading the building electric discharge of Line To Line row of channels both sides
Therefore, the safety and the people's lives and property safety of transmission facility are ensured, the generation of tripping fault is reduced.
