Abstract
The utility model relates to an insulated ranging rod which is convenient to carry and can measure the shell and the inner parts of high voltage equipment as well as related foundation size accurately and safely under the circumstance that the high voltage equipment is electrified. The insulated ranging rod adopts the technical proposal that an insulated rod is scalable, the end of the insulated rod is provided with an insulated plug, and the surface of the insulated rod is provided with length graduation marks made of insulated material; the tail section of the insulated rod is provided with an insulated handle, and an opening on the top of the first section of the insulated rod is provided with a connecting piece; internal threads are arranged in the connecting piece, and are matched with the joint bolt of an electroscope; and the outer diameter of the first section of the insulated rod is equal to or more than 15 mm. The insulated ranging rod has the advantages of simple structure, safety, reliability, scalable length, convenient carrying and accurate ranging, so the insulated ranging rod can be widely used for power engineering construction, and maintenance and repair work.
Description
One, technical field
The utility model relate to a kind of in power engineering construction and maintenance the instrument of live line measurement persistence length, height, particularly a kind of insulation ranging rod of telescopic more piece combination.
Two, background technology
At present, in electric system, along with the continuous expansion of electrical network and perfect, projects such as construction project engineering, technology innovation project equipment rebuilding are more and more, the change of foundation of civil work size in original drawing of equipment is also big, this just needs the scene to carry out size to check before construction, but transformer and distribution power station equipment belongs to high-voltage operation equipment, in order to guarantee the person and device security, " electric power safety rules " 13.11 regulations: forbid to use around the charging equipment steel tape, leather measuring tape and line chi (accompany the tinsel person) to carry out surveying work.But many this regulations of having violated are arranged in real work, use steel tape etc. to carry out in-site measurement at the scene, bring very big potential safety hazard.The use grid switching operation bar that has is measured, but the grid switching operation bar has significant limitation, and shaft is short, and weight is big, needs the more piece socket, carries inconvenience, is not with shortcomings such as scale is not easy to operate.Such as the height of measuring 10 kilovolts of bus bridges and the size of wall bushing housing etc., measurements that must have a power failure that also has, so that reduce power supply reliability increases operations staff's workload, or the like, invisiblely centrally increased difficulty to work, reduced work efficiency.Because the existence of above-mentioned several reasons brings very big trouble for work about electric power person.
Two, summary of the invention
The purpose of this utility model is can be under the charged environment of high-tension apparatus, provide a kind of can be in than short distance to the high-tension apparatus shell and innerly carry out the instrument of safety and precise measurement with relevant key dimension, and use and carry all very convenient.
For realizing goal of the invention, the technical solution adopted in the utility model is: insulating bar is the extension type structure, and its end is provided with an insulation plug, and the surface of edge bar is provided with the length scale that insulating material is made.
Hold for convenient, the insulation handle is installed on the periproct of insulating bar.
For making things convenient for the supporting use of the utility model and electroscope, thereby be applied to longer-distance high voltage testing, the head of insulating bar saves the top end opening place and is provided with a connection piece, is provided with internal thread in the web member, and this internal thread matches with galvanoscopic coupling bolt.
For can easily with the supporting use of existing electroscope, the web member that more convenient installation dimension is suitable, the head of insulating bar save external diameter and are equal to or greater than 15 millimeters.
Good effect of the present utility model is: simple in structure, safe and reliable, the scalable control of length is carried light, range finding accurately, is specially adapted to 35kV and following indoor and outdoor equipment and basic measurement work; The staff can be reduced to 2, and 1 responsible measurement is responsible for monitoring and record for 1, and is convenient and swift, improves work efficiency, and realized the purpose of the security measurement that do not have a power failure; Can with the electroscope use that organically combines, the utility model can be widely used in power engineering construction and upkeep operation.
Four, description of drawings
Fig. 1 is the whole structural representation that shortens of the utility model;
Fig. 2 is the structural representation of the utility model withdrawal;
Fig. 3 is the little partly cut-away synoptic diagram of Fig. 1 front portion.
Five, embodiment
Referring to shown in Figure 1, insulating bar 3 is an extension type round bar structure, its both ends open, and intermediate hollow is made up of by the mutual socket of branch pole that joint increases six joint external diameters.For each pole of the periproct 5 that prevents to be retracted to insulating bar drops out, the end of insulating bar 3 is provided with an insulation plug 6, the surface of insulating bar 3 is provided with the length scale 7 that insulating material is made, and this length scale 7 can be used for accurately measuring relevant length and height centimetre to be unit of quantity.
As shown in Figure 3, the head of insulating bar saves 1 top end opening place and is provided with a connection piece 8, is provided with internal thread in the web member 8, and this internal thread matches with galvanoscopic coupling bolt.Be convenient and the supporting use of electroscope, the head of insulating bar saves 1 external diameter and is designed to be equal to or greater than 15 millimeters.Electroscope and coupling bolt thereof, web member 8 are prior art, and one of ordinary skill in the art all know, and no longer describe in detail here.
The socket mode is between the merogenesis of insulating bar: the merogenesis end section of insulating bar protrudes slightly, and the protuberance external diameter is slightly larger than the internal diameter with the end of that joint of its suit.For example, when pulling out forward, the head of insulating bar saves 1 afterbody projection and has been stuck in insulating bar second joint 2 ends among Fig. 3, does not break away from insulating bar second joint 2 after pulling out, and the head of insulating bar can be retracted to when saving 1 stressed acquiring a certain degree in insulating bar second joint 2.This socket mode and other socket mode are not protection contents of the present utility model, and the personnel of affiliated technical field can both design, here no longer further narration.
During use, every joint of insulating bar can be pulled out foot, use as long hard ruler, be used to measure the height and the length of high-tension apparatus, every joint of insulating bar is designed to 1 meter, is made up of the 2-10 joint, and whole length measured scope is a 2-10 rice; Not the time spent, as shown in Figure 2, each joint of insulating bar front can be withdrawn in the periproct 5 of insulating bar, carry very convenient.
When needing high voltage testing, galvanoscopic coupling bolt is screwed in the web member 8, electroscope and the utility model are become one, can carry out remote electrical verification.
