Description
Technical field
The utility model relates to a kind of electrical test instrument, particularly a kind of New insulated testing current in resistance property of lightning arrester line erecting tools.
Background technology
Lightning arrester is used to protect the electrical equipment that in electric system, various electric equipment impacts from lightning surge, switching overvoltage, Frequency Transient Overvoltage and damages.Lightning arrester is connected between electrical network wire and ground wire usually, but is sometimes also connected between electrical equipment winding side or wire.The measurement of current in resistance property is carried out under residual voltage, can measure this value by electrostatic voltmeter, and continuous voltage can be obtained by the nameplate of lightning arrester.
During test, one end of p-wire is connected with voltage table, and the other end of p-wire is connected with the tip of lightning arrester by sharp mouth folder.The location comparison installed due to lightning arrester is high, when connecting, under needing staff to climb to operating lightning arrester framework base by ladder, free-handly to clamp at every turn, and determines to install firmly, there is the problem connecting inconvenience.Further, one group of lightning arrester has three, and the installation site of often propping up is apart from each other, causes often testing once, all needs ladder up and down back and forth once, and the test completing one group of lightning arrester will ladder three times up and down back and forth, operate very inconvenient, time-consuming, require great effort, danger is high.In addition, because the electro-mechanical part distance of positions of staff's distance top lightning arrester operation is from shorter, needs highly to maintain vigilance, to personal safety, there is great threat.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the New insulated testing current in resistance property of lightning arrester line erecting tools that a kind of design science rationally, is conveniently installed, time saving and energy saving, security is high.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of New insulated testing current in resistance property of lightning arrester line erecting tools, it is characterized in that: by mounting head, insulating bar, strap, ambulatory splint, mounting rod, spring, control wire, control handle and test transmission line are formed, C shape mounting head is installed on the top of insulating bar, strap is fixed with in the inner upper end of mounting head, the ambulatory splint of connection bar is provided with in the bottom of strap, described mounting rod is movably arranged in insulating bar, the lower end of mounting rod is connected with the spring one end be placed in insulating bar, the other end of spring is connected with the control handle be arranged in insulating bar bar wall mounting hole by control wire, control handle is shaped with groove, mounting hole setting-in on this groove and insulating bar, described test transmission line is arranged on the bottom of insulating bar and is connected with ambulatory splint.
And described insulating bar is formed by connecting with insulating bar joint by 1-4.
Advantage of the present utility model and good effect are:
1, this New insulated testing current in resistance property of lightning arrester line erecting tools, can realize away from charging equipment, just can carry out the object of installation testing on ground, eliminates and needs loaded down with trivial details by ladder, enhance the security in operating process.During use, this erecting tools is lifted lightning arrester place, upwards lift control handle, control wire drives spring elongation, thus ambulatory splint is separated with strap, then the end of lightning arrester is added to the gap place that strap and ambulatory splint are formed, decontrol control handle, make control handle return to state of nature, spring retraction, ambulatory splint coordinates with strap to be clamped the end of lightning arrester, this completes the installation of test transmission line and lightning arrester.The strap of metal material and ambulatory splint constitute a flat wire clamp, sharp mouth wire clamp before comparing, owing to increasing the contact area with lightning arrester end, so more can ensure that the contact testing transmission line and lightning arrester is good, ensure carrying out smoothly of test job.
2, this New insulated testing current in resistance property of lightning arrester line erecting tools, by insulating bar being designed to save with insulating bar the insulating bar be formed by connecting by 1-4, during use, can according to use needs, the length of insulating bar is carried out voluntarily to the adjustment of length, meet the testing requirement being positioned at differing heights arrester resistance current.Meanwhile, the design also convenient for collecting and carrying of insulating bar joint.
3, the utility model scientific structure design is reasonable, have conveniently to install, time saving and energy saving, security is high, adjustable length, convenient for collecting and the advantage of carrying, and is a kind of New insulated testing current in resistance property of lightning arrester line erecting tools with higher innovation.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Reference numeral:
1-mounting head, 2-strap, 3-ambulatory splint, 4-mounting rod, 5-spring, 6-insulating bar, 7-control wire, 8-control handle, 9-test transmission line, 10-groove, 11-mounting hole.
Embodiment
Below in conjunction with accompanying drawing, by specific embodiment, the utility model is described in further detail.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of New insulated testing current in resistance property of lightning arrester line erecting tools, its innovation is: by mounting head 1, insulating bar 6, strap 2, ambulatory splint 3, mounting rod 4, spring 5, control wire 7, control handle 8 and test transmission line 9 are formed, C shape mounting head is installed on the top of insulating bar, strap is fixed with in the inner upper end of mounting head, the ambulatory splint of connection bar is provided with in the bottom of strap, described mounting rod is movably arranged in insulating bar, the lower end of mounting rod is connected with the spring one end be placed in insulating bar, the other end of spring is connected with the control handle be arranged in insulating bar bar wall mounting hole 11 by control wire, control handle is shaped with groove 10, mounting hole setting-in on this groove and insulating bar, described test transmission line is arranged on the bottom of insulating bar and is connected with ambulatory splint.
Described insulating bar is formed by connecting with insulating bar joint by 1-4.
During use, this erecting tools is lifted lightning arrester place, upwards lift control handle, control wire drives spring elongation, thus ambulatory splint is separated with strap, then the end of lightning arrester is added to the gap place that strap and ambulatory splint are formed, decontrol control handle, make control handle return to state of nature, spring retraction, ambulatory splint coordinates with strap to be clamped the end of lightning arrester, this completes the installation of test transmission line and lightning arrester.The strap of metal material and ambulatory splint constitute a flat wire clamp, sharp mouth wire clamp before comparing, owing to increasing the contact area with lightning arrester end, so more can ensure that the contact testing transmission line and lightning arrester is good, ensure carrying out smoothly of test job.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
