Description
The present invention relates to the device of a kind of on-line monitoring insulator chain deterioration and pollution level, particularly relate to and a kind ofly be used for monitoring the ultra-high-tension power transmission line porcelain insulator and whether the silicon rubber synthetic insulators string has deterioration and insulator contamination degree device.
Existing insulator detects following several mode:
1, the degradation of porcelain insulator
Flaw detection and withstand voltage test before the insulator linked network: the maintainer steps on tower detects each porcelain insulator by " sparking distance method " null value and low value situation after the insulator linked network." sparking distance method " needs personnel Deng Ta to top, both hands are held the long insulating bar of 3-5 rice, two draw points are arranged before the insulating bar, allow the draw point discharge that on detected insulator, is short-circuited in the lower porcelain slice, several approximately mm distance of discharging gap, personnel judge the quality of porcelain insulator according to the sound of discharge.The method labour intensity is big, and the low external condition that is subject to of efficient is disturbed (corona sound, hums such as sound of the wind).
2, the filth of insulator detects
Interruption maintenance personnel Deng Ta pulls down insulator after the insulator linked network, in the middle of unloading process, reduce touching down dunghill as far as possible, and wrap with calico and to take back the laboratory, the surface filth thing is dissolved in the aquae destillata, by detecting pH value, judge the pollution level of insulator then.The method shortcoming is that labour intensity is big, and behaviour does numerous and diverse, and the time is long.
3, silicon rubber synthetic insulators is mainly by doing withstand voltage experiment in the hyperbaric chamber before the linked network, can't on-the-spotly detect after the linked network not to have again the operation data that insulate, so all very careful when each power supply administration promotes the use of.
