Line outage accident caused by inscribing happens occasionally, and therefore, the pressure test before suspension insulator use is particularly important.
It is increasing recently as the fast development of Suizhou power grid, newly-built and enlarging project of transmitting and converting electricity, causes suspension type exhausted
The demand of edge is increased sharply, so that insulator pressure test workload is huge.And existing test method is time-consuming, laborious, wiring is multiple
It is miscellaneous, working efficiency is lower is unable to satisfy field demand；In the prior art, insulator pressure test process are as follows: carry, remove insulation
Subpack；Suspension, fixed insulator；Wrapping test shorting stub；Joint test high-voltage line, ground wire；Insulator pressure build-up test；Test
Packaging is finished to carry；Wherein, suspension uses the hook of nearly 8-shaped, and respectively there are an opening in upper left and bottom right, and the opening of upper left is hung over
On cross bar, for hanging insulator, this mode is absolutely unsafe, is extremely unreliable the opening of bottom right, easily causes the insulator of bunchiness
Collapse；When wrapping test shorting stub, test shorting stub easily overhauling and the hand for scratching staff, need more shorting stubs and
And speed of wrap is slow, shorting stub is not easy to reuse；It is also laid in the prior art without dedicated shelf for cross bar.Applicant couple
Carry out the system of pressure test to suspension insulator in March, 2014 to part of in August, 2014 in maintenance branch company's electrical test class
Meter analysis, obtains following data:
Test period participates in the time-consuming total working efficiency (dividing/piece) of number sub-pieces number
2014.3.1 5 people 560 318 minutes 0.568
2014.3.5 5 people 574 325 minutes 0.566
2014.3.6 5 people 553 315 minutes 0.569
2014.3.7 5 people 567 318 minutes 0.560
2014.5.10 5 people 580 330 minutes 0.568
2014.5.12 5 people 560 320 minutes 0.571
2014.7.3 5 people 588 327 minutes 0.556
2014.7.4 5 people 574 331 minutes 0.576
2014.7.5 5 people 595 335 minutes 0.563
Applicant further counts used time ratio, obtains following original average data:
Insulator dismounting and carrying account for 46%, shorting stub winding and dismounting account for 31%, high-voltage line ground wire connect and dismounting account for 8%,
Insulator suspension accounts for 4%, rises to account for test and account for 8%, other back works and account for 3% with fixed.
Therefore, pressure test occupies a large amount of time, and wherein first three factor accounts for major part, affects speed
With progress.
