Zina zambiri

Zingwe zomwe zili pamwamba pa 35kV ndi zingwe zokhala ndi chitsulo chimodzi.Popeza kuti chingwe chachitsulo chachitsulo chimodzi chimakhala ndi chingwe cha maginito chomwe chimapangidwa ndi AC panopa mu waya wapakati, mbali ziwiri za chingwe chimodzi chokhala ndi magetsi okwera kwambiri.Chifukwa chake, njira zoyenera zoyatsira ziyenera kuchitidwa kuti magetsi asungidwe mkati mwa voteji yotetezeka (nthawi zambiri osapitilira 50V, koma osapitilira 100V ndi njira zachitetezo).Nthawi zambiri, chingwe chachitsulo chachifupi cha single-core chingwe chimakhazikika kumapeto kwina ndikuzikika kudzera mumpata kapena chitetezo chopinga kumapeto kwina.Chingwe chachitsulo chamzere wautali umodzi - chingwe chapakati chimakhazikitsidwa ndi kugwirizana kwa magawo atatu.Ziribe kanthu kuti ndi njira yanji yokhazikitsira pansi, kutchinjiriza bwino kwa sheath ndikofunikira.Pamene kusungunula kwa chingwe kumawonongeka, chitsulo chachitsulo chidzakhazikika pazigawo zingapo, zomwe zidzapangitse kuyendayenda, kuonjezera kutayika kwa sheath, kukhudza mphamvu yonyamula chingwe, komanso kuchititsa kuti chingwe chiwotchedwe. chifukwa cha kutentha kwambiri.Pa nthawi yomweyo, kutsimikizira mkulu voteji chingwe zitsulo m'chimake grounding mwachindunji kulumikiza malo n'kofunika kwambiri, ngati nthaka mfundo sangathe mogwira maziko pazifukwa zosiyanasiyana, chingwe zitsulo m'chimake kuthekera adzauka kwambiri kuti kilovolts angapo ngakhale masauzande volts. , n'zosavuta kutsogolera kuwonongeka kwa m'chimake ndi kutuluka kosalekeza, kuchititsa kukwera kwa kutentha kwa chingwe chakunja kapena kuyaka.

GDCO-301 imagwiritsa ntchito njira yozungulira.Pamene single-core chingwe zitsulo m'chimake ali pansi pa zinthu zabwinobwino (ie, mfundo imodzi grounding), kuzungulira panopa m'chimake, makamaka capacitive panopa, ndi yaying'ono kwambiri.Kamodzi kokhala ndi mfundo zambiri kumapezeka pazitsulo zachitsulo ndikupanga chipika, kuyendayenda kwamakono kudzawonjezeka kwambiri ndipo kumatha kufika kupitirira 90% ya panopa.Kuwunika kwanthawi yeniyeni kwa kayendedwe kachitsulo kachitsulo ndi kusintha kwake kumatha kuzindikira kuwunika kwapaintaneti kwa zolakwika zamitundu ingapo zachitsulo chachitsulo chachitsulo chimodzi, kuti mupeze nthawi yake komanso molondola kuti dziko lapansi lili ndi vuto, pewani kuchitika kwa ngozi ya chingwe komanso onetsetsani ntchito yotetezeka komanso yodalirika.

Imagwiritsa ntchito GSM kapena RS485 ngati njira yolumikizirana.Ndizoyenera kuyang'anira zolakwika zamitundu yambiri pazingwe zapakati pa 35kV.

Kukonzekera kwadongosolo

GDCO-301 Online Monitoring System of Curling Current pa Cable Sheath imaphatikizapo: unit yaikulu ya Integrated monitoring device ndi transformer yamakono, kutentha ndi anti-kuba sensor.Mtundu wotseguka wa transformer wamakono umayikidwa pamtunda wa chingwe cha sheath ndipo umasinthidwa kukhala chizindikiro chachiwiri chisanayambe chipangizo chowunikira.Sensa ya kutentha imagwiritsidwa ntchito poyang'anira kutentha kwa chingwe, ndipo sensa yotsutsana ndi kuba imagwiritsidwa ntchito poyang'anira mzere wozungulira.Kapangidwe ka makina owunikira pa intaneti a cable sheath ndi motere:
