Description
Technical field
The utility model relates to Special leading wire for test of lightning arrester of power transmission cable pole tower technical field, specifically a kind of Special leading wire for test of lightning arrester of power transmission cable pole tower bracing frame.
Background technology
The important device that electric transmission line lightning arrester damages from lightning overvoltage and switching overvoltage as a kind of protection circuit, cable; its safety problem is more and more paid close attention to; cable lightning arrester and cable terminal, circuit drainage thread are arranged by aluminium and are connected, in parallel with cable line.During normal operation, lightning arrester not conducting (only flowing through the Leakage Current of microampere order), when acting on the overvoltage on lightning arrester and reaching its operation voltage, lightning arrester conducting, by big current, release overvoltage energy, and by overvoltage Limiting at certain level.After release overvoltage energy, lightning arrester returns to previous status, thus ensure that cable line is not subject to superpotential damage.
For guaranteeing that lightning arrester can safe operation, the normal effect playing its conducting failure electric current, all can make a plan every year and carry out checking experiment work to lightning arrester, accomplish early investigation, early process.Because current power transmission lightning arrester is mostly arranged on above tens meters of shaft towers, checking experiment work is carried out to transmission of electricity lightning arrester before, two kinds of repair methods are substantially handled, one method is unloaded from shaft tower by lightning arrester, land laggard line correlation experiment work, again lightning arrester is reinstalled shaft tower after pass the test, this work way is not only time-consuming but also require great effort, and the long-term work high above the ground of staff, there are larger hazards, through dismantling, transmitting up and down, install, may there is phenomenon of colliding with in this external equipment, leave potential safety hazard to following operation; Another kind method is unloaded from shaft tower by lightning arrester, then the lightning arrester of pass the test already being returned installs on shaft tower, the brownout time can be saved like this, but the hazards in dismounting, installation process and potential safety hazard still exist, in addition, due to the moment standby redundancy will be retained, not only the wasting of resources is caused, and bring difficulty to depositing, costly.These two kinds of repair methods all need longer interruption duration, use a large amount of human and material resources, are easy to damage maintainer, dangerous.
Patent (the patent No.: 200920020867.8) that applicant applied for, a kind of Special leading wire for test of lightning arrester of power transmission cable pole tower, above-mentioned problems of the prior art can be solved, accelerate the speed of test, decrease the time of power failure, save manpower and materials, and substantially increase the job security of operating personnel, this dedicated pin structure is simple, safe and reliable, easy to connect in addition.
But when the above-mentioned dedicated pin applied for a patent uses, cannot fix between lead-in wire main body and test test apparatus, because lead-in wire main body is all very heavy, so tractive can be caused to copper mesh screen extraction plug, conductor plug, the unreliable of junction also can be caused even to damage.Therefore, a kind of device reliable and easy and simple to handle is needed to solve the problem.
Utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of Special leading wire for test of lightning arrester of power transmission cable pole tower bracing frame, can not be too heavy because of lead-in wire main body when this bracing frame can make test, cause the tractive of copper mesh screen being drawn to plug, conductor plug, thus make that junction is unreliable even to be damaged.
In order to solve the problem, the utility model by the following technical solutions: Special leading wire for test of lightning arrester of power transmission cable pole tower bracing frame, is characterized in that: comprise clip, main strut, claw type supporting mechanism; Described clip is connected with the top of described main strut by a cross bar, described claw type supporting mechanism comprises sliding sleeve, multiple pawls and the diagonal brace for supporting pawl, what described sliding sleeve slided is nested with on described main strut, the top of described pawl is hinged on sliding sleeve, multiple pawls are around the uniform setting of axis of main strut, described diagonal brace top is hinged on the middle part of a described pawl, and the bottom of described diagonal brace is hinged on the bottom of main strut.
Further, in this Special leading wire for test of lightning arrester of power transmission cable pole tower bracing frame, be hinged between described cross bar and described main strut, the hinged bearing diagonal in middle part of described cross bar, the lower end of this bearing diagonal is hinged on a sleeve, and what sleeve slided is nested with on described main strut, and the side of described sleeve is radially provided with through hole, described main strut is pipe fitting, arranges one and radially eject and can pass the fixture block of through hole on sleeve in main strut.
Further, in this Special leading wire for test of lightning arrester of power transmission cable pole tower bracing frame, the inner ring working face of clip is provided with rubber layer, and the surface of rubber layer is evenly equipped with some antiskid particles.
The beneficial effects of the utility model are: this bracing frame makes the connection fine rule between fixture and leading-in conductor by excessive tractive and repeatedly can not bend, thus shield jig connects the root not frangibility of fine rule.Also because fixture excessively can not be led and drag, so it is more reliable to be clamped and connected.
