Abstract
The utility model discloses a telescopic insulation ranging rod. The telescopic insulation ranging rod comprises an insulation rod consisting of a plurality of sections of insulation bars and configured to a telescopic state, wherein a scale layer is arranged on the outer wall of the insulation rod along the length direction; a rectangular insulation contact is arranged on the tail end of the insulation rod through a hinge; a pointer is also arranged on the surface of the insulation contact opposite to the insulation rod. The ranging rod provided by the utility model is simple in structure, accurate in measurement, controllable in length, and convenient in use and carrying, and can be used for measuring the case size, the inside size and the related basic sizes of live high-voltage equipment.
Description
Technical field
The utility model relates to a kind of instrument in power engineering construction and maintenance, specifically relates to a kind of telescopic insulation ranging rod.
Background technology
At present; In the electric power system of China is built; 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, and the foundation of civil work size of equipment needs change often; This just needs the scene to carry out size to check before construction for this; But transformer and distribution power station equipment belongs to high-voltage operation equipment, in order to guarantee the person and device security, regulation in " electric power safety rules ": around charging equipment, forbid to use steel tape, leather measuring tape and line chi 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.For example measure the height of 10Kv bus bridge and the size of wall bushing housing etc., measurement sometimes also must have a power failure.This has reduced power supply reliability virtually, increases operating personnel's workload, has reduced operating efficiency.
Summary of the invention
Deficiency to above-mentioned prior art; The purpose of the utility model provides a kind of telescopic insulation ranging rod; This ranging rod not only can be under the charged environment of high-tension apparatus to the high-tension apparatus shell and innerly carry out the measurement of safety and precise with relevant key dimension, and use and carry all very convenient.
To achieve these goals, the technical scheme of the utility model employing is: a kind of telescopic insulation ranging rod comprises insulating bar; Said insulating bar is made up of the more piece insulating rod, and its version is Telescoping, and is suitable long to being provided with the scale layer on the outer wall of insulating bar; Be provided with the insulation contact of a rectangular shape at the end of insulating bar; The end of insulation contact and insulating bar is hinged, and on insulation contact, also is provided with a pointer, and its pointer is positioned on the opposite face of insulation contact and insulating bar.
Preferably, said scale layer is processed by insulating material.
Preferably, said pointer is vertical with the contact-making surface of insulation contact.
Compared with prior art; The good effect of the utility model is: this ranging rod structure is simple and direct, range finding is accurate, length is controlled; It only can be under the charged environment of high-tension apparatus to the high-tension apparatus shell and innerly carry out the measurement of safety and precise with relevant key dimension, and use and carry all very convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1, insulating bar; 2, insulation contact; 11, scale layer; 21, pointer.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1, the telescopic insulation ranging rod of the utility model comprises insulating bar 1; Said insulating bar 1 is made up of the more piece insulating rod, and its version is Telescoping, and is suitable long to being provided with scale layer 11 on the outer wall of insulating bar 1; Be provided with the insulation contact 2 of a rectangular shape at the end of insulating bar 1; Insulation contact 2 is hinged with the end of insulating bar 1, on insulation contact 2, also is provided with a pointer 21, and its pointer 21 is positioned on the opposite face of insulation contact 2 and insulating bar 1.Said scale layer 11 is processed by insulating material.Said pointer 21 is vertical with the contact-making surface of insulation contact 2.
During use, can every joint of insulating bar 1 be pulled out foot, use as long hard ruler, be used to measure the height and the length of high-tension apparatus, whether correct for measurement point, whether the length that can observe pointer 21 and insulating bar 1 is consistent to compares as reference.Not the time spent,, carry very convenient with insulating bar 1 each joint withdrawal.
The above-mentioned a kind of embodiment that is merely the utility model not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all should be included within the protection range of the utility model.
Claims (3)
1. a telescopic insulation ranging rod comprises insulating bar, and it is characterized in that: said insulating bar is made up of the more piece insulating rod; Its version is Telescoping; On the outer wall of insulating bar along long to being provided with the scale layer, be provided with the insulation contact of a rectangular shape at the end of insulating bar, the end of insulation contact and insulating bar is hinged; On insulation contact, also be provided with a pointer, its pointer is positioned on the opposite face of insulation contact and insulating bar.
