Abstract
The invention relates to a grounding grid connection testing tool. The grounding grid connection testing tool is characterized by comprising a connecting column which is composed of a section of cylinder (2) and a section of cone (1), one end of the cylinder (2) of the connecting column is fixedly connected with an insulating rod (5) through a connecting base (4), filing lines or filing teeth are arranged on the surface of one end of the cone (1) of the connecting column, and in addition, at least one binding post (3) is arranged on the surface of one end of the cylinder (2). The trial use proves that after the tool is adopted, rapid grinding and testing tool connection can be achieved, and the safety of work is ensured. Meanwhile, due to the fact that the grinding face of grounding flat iron is remarkably narrowed, the phenomena that the exposed grounding flat iron is corroded and cracks can be effectively prevented, and the attractiveness and the service life of the grounding flat iron can not be influenced. The average time of the single-interval grounding connection test is shortened to about 2.75 minutes from the existing about 6 minutes, and the efficiency of the grounding grid connection test work is improved to a great extent.
Description
Technical field
The present invention relates to a kind of earth-continuity testing tool.
Background technology
The metal shell of electrical equipment must effective grounding, this be ensure personal safety, the important measures of device security.Whether earth-continuity test job is formally well connected with grounded screen the inspection carried out to the ground connection band iron of equipment, can Timeliness coverage potential safety hazard, ensures the safe and stable operation of electrical network.
But find through Long-Time Service, existing test clamp is difficult to realize good connection with ground connection band iron, its main cause is that ground connection band iron scribbles rust protection paint or corrosion is serious, although can be made moderate progress by polishing surface of contact, meeting significant prolongation working time and extensive damage rust protection paint must cause the corrosion of ground connection band iron to aggravate like this.
Summary of the invention
The object of this invention is to provide the earth-continuity testing tool that a kind of structure is simple, easy to use, good conductive can be realized with test with ground connection band iron easily and efficiently and be connected.
A kind of earth-continuity testing tool, its special feature is: comprise the joint pin be made up of one section of right cylinder and one section of cone, the cylindrical member at one end of this joint pin is fixedly connected with insulating bar by Connection Block, and on the surface of its cone one end, be provided with the cut of file or topping, on the surface of this cylindrical member at one end, be also provided with at least one binding post in addition.
Wherein Connection Block is circular tube shaped, and the two ends of this Connection Block to be set on joint pin and insulating bar and to be and are threaded.
Wherein on the surface of the cylindrical member at one end of joint pin, be provided with two planes, in these two planes, have a threaded hole separately, in threaded hole, detachably binding post is installed.
Wherein joint pin and binding post all adopt steel or copper material.
Through probationary certificate, after adopting instrument of the present invention, can polish rapidly and connecting test instrument, ensure that the safety of work.Meanwhile, owing to significantly reducing the buffed surface of ground connection band iron, exposed ground connection band iron both effectively can be prevented to be corroded and to have occurred phenomenon of rupture, unlikelyly again affect its attractive in appearance and life-span.And earth-continuity test in monospace is shortened to about 2.75 minutes by original about 6 minutes averaging time, thus improves the efficiency of grounded screen connection test job to a great extent.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is a kind of earth-continuity testing tool, comprise the joint pin be made up of one section of right cylinder 2 and one section of cone 1, right cylinder 2 one end of this joint pin is fixedly connected with insulating bar 5 by Connection Block 4, and on the surface of its cone 1 one end, be provided with the cut of file or topping, on the surface of this right cylinder 2 one end, be also provided with at least one binding post 3 in addition.Specifically on two surfaces that right cylinder 2 one end of joint pin is relative, be provided with two planes, in these two planes, have a threaded hole separately, in threaded hole, binding post 3 is detachably installed.
Specifically Connection Block 4 is circular tube shaped, and the two ends of this Connection Block 4 to be set on joint pin and insulating bar 5 and to be and are threaded.Above-mentioned joint pin and binding post 3 all adopt steel or copper material.
Using method of the present invention is:
Hold insulating bar 5 during use, by part contact exposed on the cone 1 of joint pin of the present invention tip and ground connection band iron, can test by connecting test line on binding post 3.If ground connection band iron there is no exposed part or exposed part corrosion, then can by the corner part of the cut of file on cone 1 surface or topping friction grounding band iron, obtain the bare area of a piece very little, withstand with cone 1 tip of joint pin again and guarantee that good contact can be tested, avoid and fall large-area rust preventive coating with dwarf's filing on ground connection band iron.
Claims (4)
