Description
Technical field
A kind of pole tower ground resistance testing wire of the utility model draw off gear, belongs to the technical field that power grounding resistance is measured.
Background technology
In electric system, the lightning stroke trip of transmission line of electricity is the difficult problem that puzzlement power grid security is powered always, therefore, carry out the inspection of earth system, specification ground resistance measurement method, guarantee overhead line structures reliable ground, minimizing transmission line lightning stroke accident and personal attack, become an important process of line thunder protection, therefore, power grid enterprises have formulated the surveying work that electric power standard DL/T887 " pole tower ground resistance measurement " carrys out specification earth system.
Requirement according to DL/T887 standard: powerline pole tower ground resistance test should adopt three electrode method to measure; At present, the testing wire that three electrode method measures pole tower ground resistance comprises: voltage pole testing wire and electric current pole testing wire, voltage pole testing wire and electric current pole testing wire are arranged in 4L and the 2.5L place at distance pole and tower foundation edge, and wherein, L is the extreme length of tower grounding device radiation earthing pole; In test process, because test wire and take-up work capacity are large, frequent, take-up personnel adopt nature volume to put and are easy to cause testing wire to tie a knot and confusion, cause the testing wire retractable cable time long, work difficulty and labour intensity is added to surveying work personnel, also extend the test job time, cause test job efficiency low.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is: provide a kind of and pole tower ground resistance testing wire can be made to receive and dispatch speed and the higher testing wire draw off gear of work efficiency.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of pole tower ground resistance testing wire draw off gear, comprise: retractable cable wheel, line wheel carrier and adapter shaft, described adapter shaft is rod-like structure and one end is fixed on described line wheel carrier, described retractable cable wheel is provided with axle hole and wind, described retractable cable wheel is socketed on described adapter shaft by axle hole, and the other end of described adapter shaft is provided with the retractable cable wheel connecting element come off for preventing retractable cable from taking turns;
In the utility model, described line wheel carrier is provided with: handrail handle, for the handrail handle support of fixed armrest handle with for making described line wheel carrier be fixed on the floor stand on ground; Described retractable cable wheel connecting element comprises: plain cushion and spring cotter.
The utility model compared with prior art has following beneficial effect:
1, the utility model structure is simple, easy to use, during take-up, pole tower ground resistance testing wire is fixed in retractable cable wheel, can neat for testing wire be wrapped in retractable cable wheel by rotary handle crank, during unwrapping wire, by testing wire and tested equipment connection, setting-out work can be completed by rotating backward wind; The utility model improves retractable cable speed, further increases the work efficiency of staff, and structure is simple, easy to use, practical.
2, the utility model volume little, be convenient for carrying, easy to implement, voltage pole testing wire and the testing wire folding and unfolding of electric current pole of any length can be met.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is front elevation of the present utility model;
Fig. 2 is left view of the present utility model;
In figure: 1 is retractable cable wheel, and 2 is line wheel carrier, and 3 is adapter shaft, and 4 is axle hole, and 5 is wind, and 6 is handrail handle, and 7 is handrail handle support, and 8 is floor stand, and 9 is plain cushion, and 10 is spring cotter.
Detailed description of the invention
As shown in Figure 1 and Figure 2: a kind of pole tower ground resistance testing wire draw off gear, comprise: retractable cable wheel 1, line wheel carrier 2 and adapter shaft 3, described adapter shaft 3 is for rod-like structure and one end is fixed on described line wheel carrier 2, described retractable cable wheel 1 is provided with axle hole 4 and wind 5, described retractable cable wheel 1 is socketed on described adapter shaft 3 by axle hole 4, and the other end of described adapter shaft 3 is provided with for preventing retractable cable from taking turns the 1 retractable cable wheel connecting element come off.
Particularly, the utility model is when take-up, pole tower ground resistance testing wire can be fixed in retractable cable wheel, can neat for testing wire be wrapped in retractable cable wheel by rotary handle crank, during unwrapping wire, by testing wire and tested equipment connection, can complete setting-out work by rotating backward wind.
Further, fix and ground for making line wheel carrier, and during retractable cable work, line wheel carrier is not easily rocked, described line wheel carrier 2 is provided with: handrail handle 6, for the handrail handle support 7 of fixed armrest handle 6 and the floor stand 8 for making described line wheel carrier 2 be fixed on ground, during use, one can be made to hold handrail handle 6, another hand completes retractable cable work by the wind 5 of operation retractable cable wheel 1.
In the present embodiment, described retractable cable wheel connecting element comprises: plain cushion 9 and spring cotter 10.
The utility model solves in traditional pole tower ground resistance testing wire folding and unfolding process, and the testing wire retractable cable time is long, causes the inefficient problem of test job, has substantive distinguishing features and progress; By reference to the accompanying drawings embodiments of the invention are explained in detail above, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from present inventive concept.
