The power transmission line composite strain rod tower comprises a tower body, a ground wire bracket, a middle-phase composite jumper wire string and an edge-phase composite cross arm, wherein the ground wire bracket, the middle-phase composite jumper wire string and the edge-phase composite cross arm are arranged on the tower body from top to bottom; middle-phase strain strings are arranged at the two sides of the middle-phase composite jumper wire string; an edge-phase strain string is connected with the edge-phase composite cross arm by an armor clamp. According to the power transmission line composite strain rod tower without the insulator string, the disadvantage that a common strain tower needs to be provided with the insulator string is solved under the condition that a rod tower stress and an electric gap are met; meanwhile, the disadvantages that the post-period maintenance cost is high, the width of a line corridor is great and the economical efficiency is poor are solved.
Description
Technical field:
The utility model relates to ultra-high-tension power transmission line technical field, relates in particular to a kind of strain rod tower.
Background technology:
Existing high-voltage power line tension tower all adopts traditional iron, Steel material, for meeting the requirement of electric clearance, all needs to be connected with tower body by insulator string, and the major defect causing has:
1) initial stage installing insulating substring, has increased insulator quantity of material; Later maintenance needs regularly to detect the insulating properties of insulator, has increased later maintenance cost, and economy is poor.
2) conventional anchor support adopts hard jumping mode, has strengthened wire windage yaw, takies width of corridor larger.
Utility model content:
The purpose of this utility model is to provide a kind of compound strain rod tower of transmission line of electricity of cancelling insulator string, it adopts compound strain cross arm and compound wire jumper string, effectively solve conventional anchor support and need increase insulator, the corresponding increase that causes insulator quantity of material, later maintenance cost and width of corridor, the shortcoming that economy is poor.
In order to solve existing problem in background technology, the utility model is by the following technical solutions: it comprises tower body, earth wire support, middle phase compound wire jumper string, the mutually compound cross-arm in limit, described tower body is disposed with earth wire support, middle phase compound wire jumper string, the mutually compound cross-arm in limit from the top down, the both sides of described middle phase compound wire jumper string are provided with middle phase strain insulator-string, and limit phase strain insulator-string only adopts the mutually compound cross-arm in gold utensil and limit to be connected.
The mutually compound cross-arm in described limit is also connected with tower body by limit phase composite support support.
The utility model is compared and is had the following advantages with conventional anchor support:
(1) compound anchor support has been cancelled insulator, has reduced the use amount of initial stage insulator, has saved construction cost.
(2) in phase strain insulator-string by middle phase compound wire jumper string as wire jumper support, wire jumper is walked around from jumper string outside, effectively suppress wire jumper windage yaw, limit phase strain insulator-string only adopts the mutually compound cross-arm in gold utensil and limit to be connected, because strain insulator-string is shorter, wire jumper can adopt soft jumping mode, can effectively reduce wire windage yaw, reduces circuit width of corridor.
(3) applicability is high, reduces the requirement to target line.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 1, a kind of compound strain rod tower of transmission line of electricity of cancelling insulator string, it comprises tower body 1, earth wire support 2, middle phase compound wire jumper string 3, the mutually compound cross-arm 4 in limit, described tower body 1 is disposed with earth wire support 2, middle phase compound wire jumper string 3, the mutually compound cross-arm 4 in limit from the top down, the both sides of described middle phase compound wire jumper string 3 are provided with middle phase strain insulator-string 5, limit phase strain insulator-string 6 only adopts the mutually compound cross-arm 4 in gold utensil and limit to be connected, and is also connected with limit phase composite support support 7 between the mutually compound cross-arm 4 in tower body 1 and limit.
In the utility model, with compound wire jumper string, replace wire cross-arm, strain insulator-string is installed in middle phase compound wire jumper string both sides, by middle phase compound wire jumper string as wire jumper support, wire jumper is walked around from jumper string outside, both met insulating requirements and effectively suppressed wire jumper windage yaw, limit phase strain insulator-string only adopts the mutually compound cross-arm in gold utensil and limit to be connected, because limit phase strain insulator-string is shorter, wire jumper can adopt soft jumping mode, compares with conventional steel tower, and width of corridor reduces approximately 1.5 meters.
The utility model, meeting under the condition of the stressed and electric clearance of shaft tower, has solved the shortcoming that conventional anchor support need install insulator string additional, has solved that later maintenance cost is high, circuit width of corridor is larger, the shortcoming that economy is poor simultaneously.
