Description
Technical field:
The utility model patent relates to ultra-high-tension power transmission line technical field, particularly relates to a kind of novel crossed transposition tower.
Background technology:
The conventional system scheme that current single back transmission line cut-offs is: single loop is cut-off formation double-circuit line and access a transformer station or access the transformer station being arranged in wherein the same side, loop line road after being total to one section, tower, due to the impact by actual transformer station position, the double-circuit line cut-offfing rear formation need access the transformer station being arranged in institute's hanging wire road not homonymy, and this just needs to realize coordinated transposition after line disconnection.
Conventional line coordinated transposition mode after existing single loop cut-offs mainly contains following two kinds:
1) a base four branch of a circuit tower is adopted, utilize the another side of one side of the cross-arm of upper three layers of branch tower and the cross-arm of lower three layers, access is positioned at the circuit of cross-arm not homonymy respectively, realize single back line cut-off after coordinated transposition, but four loop angle steel tower tower heads are higher, and cannot make full use of all cross-arms of four branch of a circuit towers, there is the situation of waste tower material, and cross-arm is asymmetric, tower resistance to overturning is poor.
2) after adopting a base single loop anchor support to make another loop line road of a loop line road scissors crossing, access a base double loop branch tower, realize the coordinated transposition after line disconnection, this mode adds the material of a Ji Ta, and floor space is large, be not suitable for vertical tower limited location area.
Utility model patent content:
The object of the utility model patent proposes a kind of novel crossed transposition tower, this novel shaft tower can solve single back line cut-off after coordinated transposition problem, again without the need to adopting two Ji Ta, and tower head is lower, and tower material consumption is low.
In order to solve Problems existing in background technology, the technical solution of the utility model is: it comprises tower body, tower body top is provided with " T " font ground wire cross-arm, anti-D score font topping wire cross-arm is provided with below ground wire cross-arm, be provided with below anti-D score font topping wire cross-arm " on " layer conductor cross-arm under font, described anti-D score font topping wire cross-arm is made up of the lower cross-arm on the left of the upper cross-arm of tower body both sides and tower body, described " on " layer conductor cross-arm is made up of the lower cross-arm of the upper cross-arm on the right side of tower body and tower body both sides under font.
The upper cross-arm of described anti-D score font topping wire cross-arm, lower cross-arm and " on " the upper cross-arm under font on layer conductor cross-arm, lower cross-arm end can install wire jumper support and strain insulator-string.
Described " T " font ground wire cross-arm is one deck three limit cross-arm structure, and wherein towards breaking point, another both sides are perpendicular to ground wire direction of advance.
Jumper string is hung with below described each wire jumper support.
This novel crossed transposition tower has the following advantages:
(1) cut-off with routine compared with scheme one, the utility model takes into full account that shaft tower is stressed, adopt " on " layer conductor cross-arm and anti-D score font topping wire cross-arm tower head arrangement under font, Appropriate application wire cross-arm, reduces the service condition of shaft tower, the tower head height of reduction about 25%, decrease 6 monolateral wire cross-arms, saved construction investment, cross-arm is more symmetrical, and overall structure is more stable.
(2) cut-off with routine compared with scheme two, the utility model decreases the input of a base shaft tower, reduces floor space, little by vertical tower position influence.
(3) design of " T " font ground wire cross-arm, while guaranteeing lightning protection, avoids ground wire to intersect, have compressed tower head size further.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is wiring schematic diagram of the present utility model.
Detailed description of the invention:
With reference to Fig. 1-2, a kind of novel crossed transposition tower, it comprises tower body 1, tower body 1 top is provided with " T " font ground wire cross-arm 4, anti-D score font topping wire cross-arm 2 is provided with below ground wire cross-arm 4, be provided with below anti-D score font topping wire cross-arm 2 " on " layer conductor cross-arm 3 under font, described anti-D score font topping wire cross-arm 2 is made up of the lower cross-arm on the left of the upper cross-arm of tower body both sides and tower body, described " on " layer conductor cross-arm 3 is made up of the lower cross-arm of the upper cross-arm on the right side of tower body and tower body both sides under font, the upper cross-arm of anti-D score font topping wire cross-arm 2, lower cross-arm and " on " upper cross-arm under font on layer conductor cross-arm 3, lower cross-arm end all can install wire jumper support 5 and strain insulator-string, jumper string 6 is hung with below each wire jumper support 5, described " T " font ground wire cross-arm 4 is one deck three limit cross-arm structure, wherein while towards breaking point, another both sides are perpendicular to ground wire direction of advance.
With reference to Fig. 3, Fig. 3 is wiring schematic diagram of the present utility model, the utility model utilizes the strain insulator-string 7 on anti-D score font topping wire cross-arm 2 to access right side single back line, the left lead of double-circuit line is formed after cut-offfing, utilize " on " strain insulator-string 7 under font on layer conductor cross-arm 3 accesses left side single back line, the right side wire of double-circuit line is formed after cut-offfing, and access next base double, the left and right sides wire that single back line is cut-off rear formation by the utility model adjusts to opposite side from side, thus realizes the coordinated transposition of both sides wire.
The lower cross-arm of anti-D score font topping wire cross-arm 2 is arranged on the left of tower body by establishing by the utility model, by " on " the upper cross-arm of layer conductor cross-arm 3 is arranged on the right side of tower body under font, make to keep enough electric equipment compartment distances between levels wire cross-arm, and wire jumper support 5 and jumper string 6 can be installed additional in conjunction with actual needs, guarantee that both sides wire meets the needs of wire and shaft tower electric clearance, like this under the condition meeting the stressed and electric clearance of shaft tower, by means of only a Ji Ta solve single back line cut-off after the coordinated transposition problem of wire, reduce tower head size, reduce the tower material consumption in conventional cross transposition tower simultaneously, solve the shortcoming that economy is poor, in addition anti-D score font topping wire cross-arm upper cross-arm and " on " the equal both sides of the lower cross-arm of layer conductor cross-arm are symmetrical under font, and the lower cross-arm of anti-D score font topping wire cross-arm and " on " the upper cross-arm position of layer conductor cross-arm is nearer under font, after both cancel out each other to the active force of tower body, less to the stability influence of tower body, make the overall structure of tower body more stable.
The utility model utilizes " T " font ground wire cross-arm 4 three limit cross-arm of coordinated transposition tower to access ground wire respectively; cross-arm wherein towards breaking point connects single-circuit inner side, both sides ground wire; another both sides connect single-circuit outside, both sides ground wire respectively perpendicular to the cross-arm of ground wire direction of advance; and the lightning protection of wire is guaranteed by the length of adjustment " T " font ground wire cross-arm; avoid ground wire to intersect, have compressed tower head size further.
