Description
[technical field]
This utility model belongs to overhead transmission line technical field, is specifically related to a kind of 10kV insulated overhead line system for 110kV overhead transmission line.
[background technology]
Recently as the startup of distribution network transform, the 10kV insulated overhead line system for 110kV overhead transmission line progressively adopts insulated conductor, namely makes the wire laid for outdoor aerial of outsourcing insulation with weather resistant insulant. Compared with bare conductor, insulated conductor not only has superior insulating properties, can effectively prevent the phase fault because foreign body causes, advantageously reduce and joint use the number of times that circuit has a power failure because of operation, reduce the time having a power failure because of maintenance, improve reliability and quality of voltage that line security is powered, tower structure can also be simplified simultaneously, solve tree line contradiction. Although insulated conductor has more advantages.
But, since using insulated conductor, lightning-caused breaking accident often occurs, and threatens personal safety, causes huge property economic loss. In order to solve the problems referred to above, it is presently mainly and takes the artificial method specifying insulation weak spot to the flashover that prevents an accident. Find in practice to still suffer from insulation defect according to current method, can not effectively prevent 10kV insulated overhead line lightning-caused breaking. But in current insulated overhead line system, the external state of spark gap relies primarily on manually to patrol and determines, working strength is big, and personnel expend height.
[utility model content]
In view of this, this utility model provides a kind of 10kV insulated overhead line system for 110kV overhead transmission line, overcomes the deficiencies in the prior art.
The technical scheme realizing the present utility model purpose is: a kind of 10kV insulated overhead line system for 110kV overhead transmission line, including tension-resistant rod, aerial line, cross-arm, insulator and spark gap; Aerial line is erected on described tension-resistant rod; Described cross-arm is fixedly mounted on described tension-resistant rod; One end of described insulator is connected with described aerial line, and the other end is connected with described cross-arm; Spark gap includes high-pressure side and earth terminal, and described high-pressure side is connected with described aerial line, and described earth terminal is connected with described cross-arm; Described spark gap is gap discharge formula spark gap, and cross-arm is additionally provided with the photographic head for spark gap carries out monitor in real time.

Photographic head in the present embodiment preferably employs universal photographic head; Including pedestal, it is arranged on the hemispherical transparent outer cover of base bottom, the image unit arranging in shell and the motor drive mechanism for driving image unit to rotate.
The present embodiment is additionally provided with in the shell of photographic head the wireless transmit/receive units for transmitting information with distance host.
Described arrester with series gaps is surge arrester with external series gaps, and described aerial line is positioned at the lower section of described cross-arm.
The present embodiment achieves good running protection effect, can effectively cut off the power frequency continued flow that lightning current causes, it is possible to effectively prevention 10kV insulated overhead line lightning-caused breaking. Further, since be provided with photographic head, such that it is able to the outward manifestation of spark gap is carried out monitor in real time, thus obtaining real time data in the very first time, be conducive to reply emergency situations.
The above is implemented example and only have expressed some embodiments of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims. It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model. Therefore, the protection domain of this utility model patent should be as the criterion with claims.
