Abstract
The utility model discloses a kind of high-tension laboratory Zinc-Oxide Arrester special test worktable, owing to taking, the first path bolt mother is set in work disk upper end, it is female that the female upper end of first path bolt arranges second largest footpath bolt, its feature is: when at the bottom of the lightning arrester that verifies bolt be screwed on work disk fixedly fasten mother time, the second largest footpath bolt mother of the female upper end of the first path bolt can realize can twisting jail and the silk hole Inner of self by being drawn by the lightning arrester verified bolt, that is: at the bottom of thin footpath, the inner chamber of fastening by second largest footpath bolt mother is directly screwed on the first path bolt mother, fasten at the bottom of particle size and can directly be screwed on second largest footpath bolt mother.Also owing to taking, the safe range line alarm of voice is set at work disk bottom one side; its feature is: after the round electric contact of the first lance contacts with the electric contact on the second lance of electric contact completely with end, and the safe range line alarm of voice can realize occasion protection and increase safety.
Description
Technical field the utility model relates to testing laboratory, is directly involved in high-tension laboratory Zinc-Oxide Arrester special test worktable, is specially adapted to power industry Zinc-Oxide Arrester special test and uses.
Background technology in power transmission and distribution electric system, thunderstorm season operating ultra-high-tension power transmission line safety, the safety of converting equipment, controller switching equipment and production equipment safety be all to realize lightning protection by the lightning arrester installed within the specific limits.Be generally porcelain structure with the lightning arrester used before acute, the lightning arrester of porcelain structure structure always by people extensive adopt.Namely along with the continuous progress of social development and science and technology, Zinc-Oxide Arrester comes out, and it is existing in power transmission and distribution electric system is adopted by extensive, and so far, the lightning arrester of porcelain structure structure is also eliminated thereupon.When Zinc-Oxide Arrester is after operation certain phase, leakage total current, current in resistance property, capacity current, phasing degree, current in resistance property peak value, total current peak value, fundamental active power and harmonic wave active power lightning arrester characteristic to be carried out to it to combine and test, to reach in satisfied " power equipment preventive trial code " about the requirement that lightning arrester DC and AC characteristics is measured.When carrying out Zinc-Oxide Arrester test, generally that put lightning arrester on a metal frame after, access setting test high pressure is test again, though people also find existing metal frame is put lightning arrester and carry out testting and reach expection object in long-term test work, but occasion also has certain unsafe drawback with test metal frame: one, special test worktable is not had in native system, two, tested lightning arrester is put and movability during metal frame, easy rolling curve, three, use test voltage for increasing conjunction of having a meeting, an audience, etc. well under one's control in occasion, increase within the scope of conjunction of having a meeting, an audience, etc. well under one's control the generation not having voice An full Shi Jing Xi easily to there will be unpredictable dangerous accident.
Summary of the invention the purpose of this utility model will provide a kind of high-tension laboratory Zinc-Oxide Arrester special test worktable exactly, it can solve effectively: one, do not have special test worktable in native system, two, tested lightning arrester is put and movability, easily rolling curve during metal frame, three, using test voltage for increasing conjunction of having a meeting, an audience, etc. well under one's control in occasion, increasing within the scope of conjunction of having a meeting, an audience, etc. well under one's control the drawback not having voice An full Shi Jing Xi easily to there will be the generation of unpredictable dangerous accident.
The purpose of this utility model is achieved in that high-tension laboratory Zinc-Oxide Arrester special test worktable, there is work disk and roundly fasten cylinder, it is female that described work disk upper end arranges the first path bolt, it is female that the female upper end of first path bolt arranges second largest footpath bolt, work disk one side arranges ground line pressure bolt, work disk bottom centre position is arranged roundly fastens cylinder, a round Inner that fastens arranges the first lance, first lance bottom arranges round electric contact, first lance outer setting first support spring, first lance bottom arranges second lance of end with electric contact, end is with the second lance outer setting second support spring of electric contact, work disk bottom arranges the supporting leg of equal style, work disk bottom one side arranges the safe range line alarm of voice.
The utility model arranges the first path bolt mother owing to taking in work disk upper end, it is female that the female upper end of first path bolt arranges second largest footpath bolt, its feature is: when at the bottom of the lightning arrester that verifies bolt be screwed on work disk fixedly fasten mother time, the second largest footpath bolt mother of the female upper end of the first path bolt can realize can twisting jail and the silk hole Inner of self by being drawn by the lightning arrester verified bolt, that is: at the bottom of thin footpath, the inner chamber of fastening by second largest footpath bolt mother is directly screwed on the first path bolt mother, fastens and can directly be screwed on second largest footpath bolt mother at the bottom of particle size.
Owing to taking, the first lance is set at a round Inner that fastens again, first lance bottom arranges round electric contact, first lance bottom arranges second lance of end with electric contact, its feature is: when at the bottom of the lightning arrester that verifies, bolt starts to be screwed into the internal thread of the female or second largest footpath bolt mother of the first path bolt, the first lance can realize oneself by round electric contact after the pressure of top can direct contact end portion with the electric contact on the second lance of electric contact.
Also owing to taking, the safe range line alarm of voice is set at work disk bottom one side; its feature is: after the round electric contact of the first lance contacts with the electric contact on the second lance of electric contact completely with end, and the safe range line alarm of voice can realize occasion protection and increase safety.
Appended drawings is that the utility model high-tension laboratory lightning arrester verification secure voice is warned the structure principle chart of testing table, is further described the utility model below in conjunction with accompanying drawing.
Embodiment work disk 1 upper end arranges the first path bolt mother 2, female 2 upper ends of first path bolt arrange second largest footpath bolt mother 3, work disk 1 one side arranges ground line pressure bolt 4, bottom work disk 1, centre position arranges and roundly fastens cylinder 5, round cylinder 5 Inner that fastens arranges the first lance 6, first lance 6 bottom arranges round electric contact 7, first lance 6 outer setting first support spring 8, first lance 6 bottom arranges second lance 9 of end with electric contact, end is with the second lance 9 outer setting second support spring 10 of electric contact, bottom work disk 1, week is along 3 supporting legs 11 arranging equal style, bottom work disk 1, a side arranges the safe range line alarm 12 of voice.
Installation process of the present utility model is: first work disk 1 upper end first path bolt mother 2 is welded the middle upper plane with the disk 1 that works, second largest footpath bolt mother 3 welds female 2 upper surfaces with the first path bolt, round fasten cylinder 5 reinforce with the disk 1 that works bottom on centre position, first support spring 8 is put to reinforce with the first lance 6 outer end again and is fastened cylinder 5 Inner upper end with round, second support spring 10 is put to reinforce with the second lance 9 outer end again and is fastened cylinder 5 Inner lower end with round, bottom work disk 1, a side installs the fixing safe range line alarm 12 of voice, finally by safe for voice range line alarm 12 and the first lance 6, end can complete installation with the second lance 9 of electric contact with after wire (sign) connection.
