Description
Technical field
The utility model belongs to electrical equipment technical field, relates to a kind of electric power concrete pole protector particularly.
Background technology
Electric power concrete pole, also known as making electric pole, is used to the concrete body of rod installed electric wiring, and should be noted that and carry out anti-theft protection during actual use.First, the circuit in order to avoid erection runs into lightning stroke trip, line-outage contingency occurs, and improves the reliability of power supply, on concrete bar, is usually provided with lightning arrester carries out lightning protection.Lightning protection needs, by lead-in wire, lightning current is introduced the earth, and the subject matter existed at present is the situation that lead-in wire is stolen that often occurs, thus when causing thunderstorm weather, stolen rear remaining lead-in wire forms short circuit, causes trip accident, jeopardizes personal safety time serious; Secondly, except having the situation of stealing lightning protection lead-in wire, also there is the problem of stealing earth electrode joint in the concrete bar of existing installation.According to power industry standard, the method that concrete rod grounded pole joint is with bolts, does not almost have anti-theft feature.Traditional mode overwhelming majority adopts the mode of Anti-theft cap to carry out antitheft, and some adopts the mode of welding, although meet antitheft requirement, does not meet the requirement of technical regulation, so be not general method in power industry.And but the mode of the built-in ground connection of earth electrode joint is subject to the restriction of geographical position and shaft tower environment, how solves the extremely antitheft problem of tower grounding, just become the task of top priority.
Summary of the invention
The utility model is to solve the problems of the technologies described above, and provides a kind of and can avoid lightning protection lead-in wire and the stolen electric power concrete pole protector of earth electrode joint.
The technical solution of the utility model is: a kind of electric power concrete pole protector, comprise concrete bar, the upper end of described concrete bar is provided with patch bay, patch bay is provided with lightning arrester, lightning arrester is connected with connecting line, the lower end of described concrete bar is connected with earth electrode protection of welded joints block, described earth electrode protection of welded joints block is notch cuttype, earth electrode protection of welded joints block comprises protective block one from top to bottom successively, protective block two and protective block three, the width of protective block three is greater than the width of protective block two, the width of protective block two is greater than the width of protective block one, protective block one is provided with builds mouth and is positioned at more than ground, protective block two and protective block three locate below ground level, the periphery of protective block two and protective block three is provided with connecting rod, the outside of concrete bar is provided with connecting line protective frame, the upper end of connecting line protective frame is connected with patch bay, the lower end of connecting line protective frame is connected with protective block one, the middle part of connecting line protective frame is connected with warning sign by warning sign support.
Preferably, the width of described protective block one is 80cm.
Further, the width of described protective block two is 120cm.
Further, the width of described protective block three is 160cm.
Preferably, described connecting rod is welded on protective block two and protective block three.
Preferably, described warning sign support is connected with connecting line support by bolt.
The beneficial effects of the utility model are: first, by arranging earth electrode protection of welded joints block, first earth electrode joint is put in the lower end of concrete bar during installation, then from building mouth to casting concrete in earth electrode protection of welded joints block, thus concrete bar, built on stilts downlead and connector are formed integrative-structure, be connected firmly, both met antitheft needs, the requirement of earth resistance can be met again; In addition, in order to improve anti-theft effect, earth electrode protection of welded joints blocks design being become forge piece of step type structure, namely comprising three protective blocks that width increases from top to bottom successively, first protective block larger for width being put into below ground during installation, and connecting rod is set in its periphery.When have people to steal joint upwards pull up concrete bar time, because the effect of connecting rod and notch cuttype protective block can increase resistance, thus can effectively avoid joint to be stolen.
Secondly; in concrete bar outer setting connecting line protective frame; the connecting line of lightning protection is placed in protective frame; the personnel of stealing can be avoided arbitrarily to cut connecting line; the connecting line exposed problem occurring lightning current ability of the drawing decline that corrosion causes outside for a long time can be avoided simultaneously; and then thunderstorm weather generation trip accident can be avoided, improve the fail safe used.Meanwhile, connecting line protective frame arranges warning sign, nearby to play the potential safety hazard caused to avoid personnel.
