Description
Technical field
The utility model relates to electric system anti-thunder technical field, specially a kind of distribution composite insulation cross arm.
Background technique
Cross-arm is the angle bar that electric pole top is laterally fixed, and has porcelain vase above, for supporting trolley wire.The work of cross-arm
With: cross-arm is component part important in shaft tower, its effect is for installing insulator and fitting, to support conducting wire, take shelter from the thunder
Line, and be allowed to keep certain safe distance by regulation.
According to result of study it is found that lightning stroke flashover depends on overvoltage value and line insulation is horizontal, research shows that lightning stroke is drawn
The electric arc severity risen is reduced with the reduction along the electric-force gradient of flashover path, so it is horizontal to improve line insulation
Lightning stroke flashover can be significantly improved with the insulation performance for increasing electric force pole tower.
Application No. is CN201620170700.X, a kind of entitled utility model for installing cross-arm on utility poles is special
Benefit, including the first cross-arm, are equipped with the second cross-arm and third cross-arm above and below the first cross-arm, the first cross-arm, the second cross-arm, the
The two sides of three cross-arms are equipped with mounting hole through firm bar connection, the first cross-arm, the second cross-arm, third cross-arm, and the first cross-arm is through even
It connects ring and is connected with anchor ear, anchor ear includes two semicircle anchor ears, is connected between two semicircle anchor ears through multiple connecting rods, semicircle
One end of shape anchor ear connects cambered hook, and the radian plate of two semicircle anchor ears of connection, semicircle anchor ear are equipped between radian hook
The other end be connected with cylindrical bar corresponding with radian hook through spring, the intermediate position of cylindrical bar is cased with not to be overlapped with its center
Cam post, cam post be equipped with handle；The utility model is easy for installation, it is not easy to fall off.
But the electric power of 35 kilovolts of domestic distribution network system and overhead distribution below, especially 10 kilovolt at present
Overhead transmission line generallys use angle bar cross-arm, the metallic conduction characteristic of itself, does not have insulating effect, and run certain year
Post-etching gets rusty after limit, reduces intensity, brings certain trouble to maintenance from now on, and because not having insulating properties not have lightning protection
Effect, therefore devise a kind of distribution composite insulation cross arm.
Summary of the invention
In order to overcome the shortcomings of prior art, the utility model provides a kind of distribution composite insulation cross arm, can be effective
Solve the problems, such as background technique propose.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of distribution composite insulation cross arm, including cross-arm body, the cross-arm body are a hollow rectangular tube, and horizontal
The both ends for carrying on a shoulder pole ontology are enclosed construction, medial surface are provided in the cross-arm body, the medial surface lower end is connected with fitting
Attachment, the cross-arm body both ends are lateral surface, are provided with vertical plane in the cross-arm body, are provided with circle in the vertical plane
Through-hole.
Further, the pipe thickness of the cross-arm body is 6-8mm.
Further, spacing is 1695-1705mm between the round tube hole.
Further, the cross-arm body is made of composite insulating material.
Compared with prior art, the utility model has the beneficial effects that
It is novel that the distribution composite insulation cross arm of the utility model constructs, and is easily installed, is constructed using rectangular tube, and intensity is high
In traditional angle bar cross-arm, surface is smooth, has hydrophobicity and self-cleaning function, avoids on it that there are moisture or dustiness etc. to lead
The surface insulated decline of cross-arm is caused, overhead transmission line is reduced because of line-outage contingency caused by being struck by lightning, reduces trip-out rate, greatly mention
The high safety of power grid, is worthy to be popularized.
