Abstract
The invention relates to a tester for an arrester on a 66kV tower. The tester comprises an insulating cover, an insulation shielding cable and a shielding line, wherein the edge of the insulating cover is provided with an insulation hook, the insulation shielding cable is provided with an insulation hanging ring, the insulation hook is movably connected with the insulation hanging ring and the insulation shielding cable is connected with the shielding line; the outer surface of the insulation shielding cable is coated with a shielding mesh. During testing, only power transmission workers climb up the iron tower to remove arrester leads, connect test cables, fasten the insulation shielding cover and fix the test cable, and the arrester can be tested on the tower, thus the tester is easily used, saved in labor, shortened in time, safe and reliable.
Description
Technical field
The present invention relates to a kind of power equipment testing equipment, particularly relate to lightning arrester exerciser and test method thereof on a kind of 66kV tower.
Background technology
Newly-built and new transformation transformer station all adopts the canned fully-closed switch equipment of metal (GIS) into and out of line interval at present, 220kVGIS adopts sleeve pipe to connect overhead transmission line into and out of line, lightning arrester is arranged on into and out of in institute of Xian Kouji transformer station, tests more convenient; 66kVGIS then adopts cable to be connected to pole line on tower into and out of line, zinc oxide surge arresters on tower, very inconvenient during test.According to repair based on condition of component regulations stipulate, on tower, lightning arrester should carry out a 1mA initial voltage U for every 3 years
1mAand 75%U
1mAleakage current is tested.Due to lightning arrester, on tower, apply DC voltage higher, and lightning arrester and surrounding objects more closely cannot normal assays, so lightning arrester is pulled down from tower by power transmission workman during test, under lightning arrester being transported to tower with rope, pulley, test again lightning arrester to be moved on tower and installed.Each test needs power transmission workman to divide two groups, tears lightning arrester open for one group on tower, and another group, at the drop-down lightning arrester of tower, is waste of manpower like this, and incurs loss through delay power off time, and add many unsafe factors.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide lightning arrester exerciser on a kind of 66kV tower, solve in prior art the problem tested and waste time and energy.
Another object of the present invention is to the test method that lightning arrester exerciser on a kind of 66kV tower is provided.
Technical scheme of the present invention is as follows:
Comprise insulating boot, insulation shielding cable and shielding line, the edge of insulating boot is provided with insulating hanger, insulation shielding cable is arranged insulation link, and insulating hanger is flexibly connected with insulation link, and insulation shielding cable connects shielding line; The coated gauze screen of insulation shielding cable outside surface.
Described insulating boot is provided with carry hand.
Described insulating boot is the cylindrical shape of thickness 7mm.
Described insulation shielding cable length is the height of two lightning arresters.
Test method of the present invention comprises the steps:
Dismounting lightning arrester goes between, insulation shielding cable is articulated in the screw hole of lightning arrester connection terminal, insulation shielding cable can touch any grounding body, insulation shielding cable length is two lightning arrester height, shielding line is connected again after insulation shielding cable, shielding line does not allow to contact any grounding body, and insulation shielding cable length should to be received under tower till high-voltage D.C. generator; Above lightning arrester, insulating boot is loaded onto after wiring completes.
Advantageous effect of the present invention is as follows:
1, by insulating boot, insulation shielding cable and shielding line structure, power transmission workman is only needed to climb up steel tower during test, dismounting lightning arrester goes between, test cable in connection, buckle insulation shielding cover again, fix test cable, test of lightning arrester just can carry out on tower, use simple, save manpower, the shortening time, safe and reliable.
2, insulating boot and insulation shielding cable are linked up with by link and are flexibly connected, and can change different insulating boots or insulation shielding cable as required, flexible operation, reduces costs, convenient for maintaining.
3, insulating boot is provided with carry hand, handled easily personnel Deng Ta operation.
4, insulation shielding cable outsourcing gauze screen, improves insulating property, bears more than 150kV DC break down voltage and does not puncture.
5, insulating boot is the cylindrical shape of thickness 7mm, through verification experimental verification, namely has reliable shielding, again can proof strength, and weight reduction, reduces costs, and cost performance is the highest.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is using state structural representation of the present invention.
In figure, 1, insulating boot, 2, insulation shielding cable, 3, shielding line, 4, high-voltage D.C. generator, 5, steel tower, 6, carry hand, 7, hook, 8, link.
Embodiment
Referring to accompanying drawing, in conjunction with having embodiment, describe the present invention in detail.
Embodiment
Comprise insulating boot 1, insulation shielding cable 2 and shielding line 3, insulating boot adopts electro-insulating rubber to be made for the cylindrical shape of thickness 7mm, insulating boot is provided with carry hand 6, the edge of insulating boot is provided with insulating hanger 7, insulation shielding cable is arranged insulation link 8, insulating hanger is flexibly connected with insulation link, and insulation shielding cable connects shielding line; Insulation shielding cable adopts crosslinked polyethylene to be insulating material, the coated gauze screen of insulation shielding cable outside surface, and insulating property are born more than 150kV DC break down voltage and do not puncture; Described insulation shielding cable length is the height of two lightning arresters.Shielding line adopts the gummed wire of band shielding.
Test method of the present invention comprises the steps:
Dismounting lightning arrester goes between, then insulation shielding cable is articulated in the screw hole of lightning arrester connection terminal, insulation shielding cable can touch any grounding body, insulation shielding cable length is two lightning arrester height, after insulation shielding cable, connect shielding line again, shielding line does not allow to contact any grounding body, because shielding line is in order to weight reduction, insulating property are lower, and shielding line length should to be received under tower till high-voltage D.C. generator.Above lightning arrester, load onto insulating boot after wiring completes, when avoiding testing, lightning arrester and surrounding objects close together are discharged or affect the accuracy of test figure.After more than having worked, testing crew just can complete the test mission to lightning arrester on tower under tower.
