Kodi mungapewe bwanji kugunda kwa mphezi pamizere yamagetsi yamphamvu kwambiri?

Nthawi zambiri, mzere wonse wa mzere wa UHV umatetezedwa ndi waya wapansi, kapena waya pansi ndi chingwe chowunikira cha OPGW, chomwe chimakhala ndi zotsatira zina zachitetezo cha mphezi pamizere yotumizira ma UHV.Njira zodzitetezera ku mphezi ndi izi:

GDCR2000G Earth Resistance Tester

1. Chepetsani mtengo wa kukana kwapansi.Kaya kukana kwapansi kuli kwabwino kapena ayi kudzakhudza mwachindunji kukana kwa mphezi pamzere womwe ukugunda mbande.Onetsetsani kugwirizana kodalirika pakati pa nsanja ndi kondakitala wapansi.Pokonza tsiku ndi tsiku, onjezani kulondera ndikutsata mosamalitsa nthawi yoyeserera ya mzere kuti muyese kukana kwapansi.Ndikofunikiranso m'madera apadera.Kufupikitsa nthawi yoyeserera.M'mizere yotumizira mphamvu yamapiri, mitengo ina ili pamwamba pa phirilo.Mitengo iyi ndi yofanana ndi mitengo yayitali ndipo iyenera kuwonedwa ngati nsanja zowonjezera.Nthawi zambiri amakhala pachiwopsezo cha kugwa kwachuma, ndipo ayenera kuyang'ana kwambiri pakuchepetsa kukana kukhazikika.Choncho, tikulimbikitsidwa kugwiritsa ntchito HV HIPOT GDCR2000G Earth Resistance Tester kuti muyese kukana pansi kwa nsanja nthawi zonse.Oyenera pansi amatsogolera akalumikidzidwa osiyanasiyana (zozungulira zitsulo, lathyathyathya chitsulo ndi ngodya zitsulo).Clamp-on ground resistance tester imagwiritsidwa ntchito kwambiri poyesa kukana kwamphamvu kwamagetsi, matelefoni, meteorology, malo opangira mafuta, zomangamanga ndi zida zamagetsi zamagetsi.

2. Konzani chingwe cholumikizira pansi.Khazikitsani chingwe cholumikizira pansi (kapena pafupi) ndi waya, womwe ungathe kugwira ntchito yotsekereza ndi kulumikiza nsanjayo ikawombedwa ndi mphezi, ndiyeno voteji yomwe insulator imanyamula idzawongolera kukana kwa mphezi pamzere.

3. Ndi bwino kuonjezera chiwerengero kapena kutalika kwa insulators kuti muwonjezere mphamvu ya zotetezera pamene mukuonetsetsa kuti mphepo yapatuka pa chingwe cha insulator.

4. Ikani ndodo yotulutsa mphezi pamwamba pa nsanja yamapiri kapena mutu wa nsanja m'malo omwe mphezi zimawomba pafupipafupi.

5. Pofuna kupewa kuwotcha kwa ma frequency arc arc ndi ndalama zotsogola chifukwa cha kugunda kwa mphezi, chitetezo chofulumira cha relay chiyenera kugwiritsidwa ntchito momwe mungathere kuti muchepetse nthawi yaulendo.Kuwomba kwa mphezi zambiri kumakhala kung'anima kwa gawo limodzi, kotero kutsekanso kwagawo limodzi kuyenera kugwiritsidwa ntchito momwe mungathere.

6. Mzere watsopano wopatsirana umasintha mawonekedwe a mutu wa nsanja panthawi ya mapangidwe a nsanja, kuti achepetse chitetezo cha waya wapansi kwa woyendetsa.Ndiko kugwiritsa ntchito ngodya yodzitchinjiriza m'malo otetezedwa ndi mphezi kuti muchepetse mphezi yotchinga.

7. Posankha njira yoyendetsera mzere woyambira pamwamba, pewani madera akumatauni omwe amakonda kugunda ndi mphezi.
