Abstract
The utility model discloses a straight-line cable T-jointing steel tube rod tower which comprises a base and a rod body. The base is fixed at the lower end of the rod body. The straight-line cable T-joint steel tube rod tower is characterized in that two cathead main tubes are fixed at the upper end of the rod body, cathead transverse beams are fixed at upper ends of the two cathead main tubes, cable hanging points are arranged on two ends and the middle portion of each cathead transverse beam, two arrester upper supports are fixed on the cathead transverse beams, and arrester lower supports are fixedly arranged on the lower portions of the cathead main tubes. The straight-line cable T-joint steel tube rod tower is safe in structure and low in construction price and brings convenience to installation of arresters. When original line transformation or straight-line cable T jointing is carried out, total project cost can be effectively reduced, and electrical insulation level of an original line is improved. The rod tower is safe in structure and low in construction price, the construction price can be effectively reduced when horizontally-arranged electric transmission line moving or the straight-line cable T jointing is carried out, and the construction price is about a half of common design project.
Description
Technical field
The utility model relates to a kind of improvement of shaft tower, specifically a kind of straight line cable T connection steel pipe pole tower.
Background technology
In the electrical network of present stage, 35kV or 110kV circuit mostly are the cement pole patterns of original design, and two bar pattern lead major parts are horizontal.Because economic development, highway, factory building etc. need be built in original overhead line structures position, and circuit is badly in need of removing, and take up an area of, coordinate mutually with surrounding environment for reducing simultaneously, and the shaft tower after the migration adopts the steel pipe pole pattern.Traditional steel pipe pole single loop major part is triangle arrangement, the type of array of this kind type of array and former circuit (horizontally) is inconsistent, after the triangle arrangement construction, usually cause the string skew of dangling on the shaft tower of new hack lever tower both sides, with shaft skew in opposite directions in the stylish vertical rod tower, shorten the electrical distance on the shaft tower, caused line-to-ground fault easily; If adopt the strain insulator shaft tower, lead can adopt horizontally, but has really improved construction costs greatly, generally is about 2 times of straight line pole cost; If adopt straight line pole, when cable T connect, during the lead triangle arrangement, wire spacing can not meet the demands, and arrester can't arrange.
Summary of the invention
The purpose of this utility model be to provide a kind of when carrying out horizontal transmission line of electricity migration or straight line pole T use straight line cable T connection steel pipe pole tower simple in structure, that cost is low, safe and reliable when connecing.
In order to reach above purpose, the technical scheme that the utility model adopts is: straight line cable T connection steel pipe pole tower, comprise base and shaft, base is fixed on the lower end of shaft, it is characterized in that: two cat heads are responsible on fixing in the upper end of shaft, fix the cat head cross-arm in the upper end that two cat heads are responsible for, and the two ends of cat head cross-arm and middle part all are provided with the cable suspension point, two arrester upper brackets on the cat head cross-arm is fixing, the bottom of being responsible at two cat heads all is fixed with the arrester lower carriage.
The utility model is also implemented by following measure: described arrester upper bracket is vertical with the cat head cross-arm, and the arrester lower carriage is parallel with the arrester upper bracket, and on a vertical plane.
The interior angle that described two cat heads are responsible for the lower end is 60-79 degree.
The beneficial effects of the utility model are: structural safety, cost is low, arrester is easy for installation, when original track remodelling or straight line cable T connect, can effectively reduce project total cost, and improve the electrical insulation level of original circuit.Structural safety, the shaft tower that cost is low when carrying out the migration of horizontal transmission line of electricity or straight line pole T when connecing, can effectively reduce construction costs, are about half of common project engineering cost.
Description of drawings
Fig. 1 looks schematic diagram for structure master of the present utility model;
Fig. 2 looks schematic diagram for the right side on top of the present utility model;
Among the figure: 1, base; 2, shaft; 3, cat head is responsible for; 4, cat head cross-arm; 5, arrester upper bracket; 6, cable suspension point; 7, arrester lower carriage.
The specific embodiment
Make the utility model with reference to accompanying drawing 1, Fig. 2.This straight line cable T connection steel pipe pole tower, comprise base 1 and shaft 2, base 1 is fixed on the lower end of shaft 2, it is characterized in that: two cat heads are responsible for 3 on fixing in the upper end of shaft 2, cat head cross-arm 4 on fixing in two cat heads person in charges' 3 upper end, the two ends of cat head cross-arm 4 and middle part all are provided with cable suspension point 6, so that three cables are suspended on two ends and the middle part of cat head cross-arm 4 respectively, fix two arrester upper brackets 5 at cat head cross-arm 4, bottom two cat heads persons in charge 3 all is fixed with arrester lower carriage 7, so that arrester is installed in the both ends of arrester upper bracket 5 and arrester lower carriage 7.
Described arrester upper bracket 5 is vertical with cat head cross-arm 4, and arrester lower carriage 7 is parallel with arrester upper bracket 5, and on a vertical plane.
It is that the steel pipe of 300mm is made that described cat head cross-arm 4, arrester upper bracket 5 and arrester lower carriage 7 can adopt diameter, cat head cross-arm 4 mainly carries wire weight and satisfies the electrical distance requirement, length can be determined according to line voltage distribution grade and span, be generally 4.2m.Arrester upper bracket 5 and arrester lower carriage 7 are mainly used in installing arrester, make cable head that lightning protection be arranged, and for satisfying the electrical distance requirement, both ends are not less than 1.5m apart from cat head cross-arm 4 simultaneously.
The interior angle that described two cat heads are responsible for 3 lower ends is 60-79 degree.
Described shaft 2 is the supporting member of whole shaft tower, and overall height can be adjusted as required, is generally 14.5m, and for ease of installing and transportation, being divided into is two joints, and the centre connects by flange.
During use, the utility model group is stood on the circuit below, connect by straight line, simple in structure, construction costs is low.
