Abstract
Insulating overhead earth wire discharge gap is apart from detecting specialized tool, this instrument include that mutual welded front end detects head (1), intermediate junction pole (2) and rear end activity and connects (3), with movable insulating bar (4) that connect swing joint in rear end, the front end detects the head and is the big trapezoidal measuring head in the little bottom surface of top surface, and activity joint in rear end is cavity area internal screw thread pipe, and insulating bar is through the external screw thread of its front end and the interior screw thread fit connection of rear end activity joint. The utility model discloses the operation is safe, make things convenient for, save time, laborsaving, easy detection, more can guarantee the testing result accuracy.
Description
Technical field
The utility model relates to transmission line faultlocating technical field of tools, the specific purpose tool of especially transmission line insulator aerial earth wire discharging gap distance detection.
Background technology
In prior art, the main steel tape of transmission line insulator aerial earth wire discharging gap distance detects, because the induced electricity on insulated static wire is larger, working earthing line need be set up at the two ends detecting shaft tower section during detection, after individual protective earth line set up by the shaft tower that need detect at every base again, can carry out testing, operation has following drawback like this: 1. classic method needs operating personnel to carry ground wire to step on tower, physical demands when adding work high above the ground personnel Deng Ta and Deng Ta difficulty.2. on the circuit run, carry ground wire step on the personal safety that tower is unfavorable for operating personnel.3. every base shaft tower is set up and removes ground wire, time and effort consuming.4., due to discharging gap low about 50cm more general than earth wire support hanging wire point, during detection, operating personnel needs to bend to operate steel tape, and physical demands is large.5. the gauged distance of discharging gap is 20mm, and permissible error is that ± 2mm, ± 2mm naked eyes difficulty is distinguished, large with steel tape metrical error, is difficult to the accuracy ensureing testing result.
Summary of the invention
The purpose of this utility model just in order to overcome above-mentioned the deficiencies in the prior art, provide a kind of safe, convenient, save time, laborsaving, be easy to detect, more can ensure the discharging gap special detection tool of testing result accuracy.
The purpose of this utility model is achieved by the following technical solution.
Insulated static wire discharging gap distance detects specific purpose tool, and this instrument comprises the front-end detection head, middle brace rod and the rear end active joint that are welded to each other, the insulating bar be flexibly connected with rear end active joint; Described front-end detection head is the large trapezoidal detection head in the little bottom surface of end face, and rear end active joint is the tapped pipe of hollow, and insulating bar is connected with the screw-internal thread fit of rear end active joint by the external thread of its front end.
Front-end detection head described in the utility model is the trapezoidal detection head of the long 18mm of top margin, the bottom side length 22mm cut into the steel plate that thickness is 12mm, high 50mm.Described middle brace rod diameter is 10mm, the steel bar meter of long 50mm forms, described rear end active joint adopt diameter be 30mm, the hollow belt internal thread of long 50mm and top mouth close metal tube process.
The utility model is compared with traditional detection method, not be used in the two ends detecting shaft tower section and set up working earthing line, also not be used in every base shaft tower and set up individual protective earth line, thus avoid every base shaft tower and carry the present situation that ground wire steps on tower, improve the security of operation on operating personnel's tower, alleviate the instrument load of high-altitude personnel, save the time of setting up and removing ground wire.The downward 50cm that need not bend during detection operates, and detection head is fixed measure, only detection head need be inserted the size that discharging gap just can be easy to distinguish clearance distance, save time, laborsaving, accurate, handled easily.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model;
Schematic diagram when Fig. 3 is the utility model detection discharging gap.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises front-end detection 1, middle brace rod 2, rear end active joint 3, three parts by being welded into an entirety, connects insulating bar 4 finally by rear end active joint 3.Described front-end detection 1 is the large trapezoidal detection head in the little bottom surface of end face, with the steel plate that thickness is 12mm cut into the long 18mm of top margin, bottom side length 22mm, high 50mm trapezoidal.Rear end active joint 3 is the tapped pipe of hollow, employing diameter is 30mm, the hollow belt internal thread of long 50mm and top mouth close metal tube process.Middle brace rod 2 with diameter be 10mm, the steel bar meter of long 50mm forms.Insulating bar 4 is connected with the screw-internal thread fit of rear end active joint by the external thread of its front end.
When adopting the utility model to detect discharging gap, as shown in Figure 3, by hand-held insulating bar 4 by a front-end detection 1 insertion discharging gap 5, gauged distance due to discharging gap is 20mm, and permissible error is ± 2mm, and the long 18mm of the end face of front-end detection head, the long 22mm in bottom surface, be just error amount, so front-end detection head just can be inserted discharging gap 5 for qualified, have gap to be after insertion and exceed max value of error 22mm; Otherwise front-end detection head can not be inserted to be and be less than error minimum value 18mm, thus distance that is convenient, fast, that judge discharging gap exactly whether can meet code requirement.
The utility model safety, convenient, save time, laborsaving, be easy to detect, more can ensure the accuracy of testing result, tower is stepped on because operating personnel does not need to carry ground wire, physical demands when reducing work high above the ground personnel Deng Ta and Deng Ta difficulty, also improve the personal safety of operation on working line, during detection, operating personnel does not need to bend to operate steel tape, reduce the physical demands of operating personnel, the most key is detection head is fixed measure, discharging gap can be inserted, just can be convenient, fast, judge whether the distance of discharging gap meets code requirement exactly, improve the accuracy of testing result.
