Ngokuqhelekileyo, umgca wonke womgca we-UHV ukhuselwe ngocingo oluphantsi, okanye ucingo oluphantsi kunye ne-OPGW optical cable, enemiphumo ethile yokukhusela umbane kwiintambo zokuhambisa i-UHV.Amanyathelo athile okukhusela umbane ngala alandelayo:
GDCR2000G Umvavanyi wokuchasa umhlaba
1. Nciphisa ixabiso lokuchasana komhlaba.Ingaba ukuchasana komhlaba kulungile okanye akunjalo kuya kuchaphazela ngokuthe ngqo inqanaba lokumelana nombane lomgca obetha ngokuthe ngqo izithole.Qinisekisa uqhagamshelo oluthembekileyo phakathi kwenqaba kunye nomqhubi ophantsi.Ekugcinweni kwemihla ngemihla, ukwandisa i-patrol kwaye ulandele ngokungqongqo ixesha lokuvavanya kwangaphambili lomgca ukulinganisa ukuchasana komhlaba.Kwakhona kuyimfuneko kwiindawo ezikhethekileyo.Lifutshane ixesha lovavanyo lwangaphambili.Kwiintambo zokuhambisa amandla ezintabeni, ezinye iipali zikwincopho kunye nomqolo wentaba.Ezi pali zilingana neepali eziphakamileyo kwaye kufuneka ziphathwe njengeenqaba eziphakamileyo.Bahlala babe ngamanqaku asemngciphekweni wokuwa kobutyebi, kwaye kufuneka bagxile ekunciphiseni ukuxhathisa.Ngoko ke, kucetyiswa ukuba usebenzise i-HV HIPOT GDCR2000G Earth Resistance Tester ukulinganisa ixabiso lokumelana nomhlaba kwinqaba rhoqo.Ilungele ukukhokela komhlaba kwiimilo ezahlukeneyo (intsimbi ejikelezayo, intsimbi eyisicaba kunye nentsimbi ye-angle).I-Clamp-on ground resistance tester isetyenziswa ngokubanzi kumlinganiselo wokumelana nomhlaba wamandla ombane, unxibelelwano lomnxeba, i-meteorology, intsimi yeoli, ukwakhiwa kunye nezixhobo zombane zoshishino.
2. Misa ucingo oludibanisa umhlaba.Cwangcisa umgca wokudibanisa phantsi (okanye kufuphi) nocingo, onokudlala indima yokucima kunye nokudibanisa xa inqaba ibethwe ngumbane, kwaye emva koko i-voltage ethwala i-insulator yenqaba iya kuphucula umgangatho wokumelana nombane womgca.
3. Kungcono ukwandisa inani okanye ubude be-insulators ukwandisa amandla empembelelo ye-insulators ngelixa uqinisekisa ukuphambuka komoya womtya we-insulator.
4. Faka intonga yombane elawulwayo ephumayo encotsheni yentaba okanye intloko yenqaba kwiindawo apho umbane ubetha rhoqo.
5. Ukuze kuthintelwe ukutsha kwe-arc frequency yamandla kunye nemali ekhokelayo ebangelwa kukubetha kombane, ukukhuselwa ngokukhawuleza kwe-relay kufuneka kusetyenziswe kangangoko kunokwenzeka ukunciphisa ixesha lohambo.Uninzi lokubetha kombane lukwinqanaba elinye, ke ukuvala okuzenzekelayo kwesigaba esinye kufuneka kusetyenziswe kangangoko kunokwenzeka.
6. Umgca omtsha wothumelo utshintsha isakhiwo sentloko yenqaba ngexesha loyilo lwenqaba, ukwenzela ukunciphisa i-angle yokukhusela yocingo lomhlaba kumqhubi.Kukusebenzisa i-angle yokukhusela engafanelekanga kwiindawo eziphambili zokukhusela umbane ukunciphisa izinga lokukhusela umbane.
7. Xa ukhetha indlela yokusetwa kokuqala komgca ongaphezulu, gwema iindawo zasezidolophini ezithanda ukuduma kunye nombane.
