Namhlanje, i-GL ithetha ngamanyathelo aqhelekileyo malunga nendlela yokuphucula uzinzo lwe-thermalIintambo ze-OPGW:
1. Indlela yomgca we-shunt
Ixabiso leOPGW intambo yokubonaiphezulu kakhulu, kwaye akukho qoqosho ukwandisa kuphela icandelo elinqamlezayo ukuthwala i-short-circuit current.Ngokuqhelekileyo isetyenziselwa ukuseta umgca wokukhusela umbane ohambelana nentambo ye-OPGW optical ukunciphisa i-current ye-OPGW optical cable.
Ukukhethwa komgca we-shunt kufuneka kuhlangane:
a.Yiba ne-impedance ephantsi ngokwaneleyo ukwenza i-OPGW yangoku yehla ngaphantsi kwexabiso elivumelekileyo;
b.Iyakwazi ukudlula umsinga omkhulu ngokwaneleyo;
c.Kufuneka kubekho ukhuseleko lwamandla okwaneleyo ngelixa uhlangabezana neemfuno ezahlukeneyo zokhuseleko lombane.
Kufuneka kwakhona kuqatshelwe ukuba nangona ukuchasana komgca we-shunt kungancitshiswa kakhulu, ukusabela kwayo kwe-inductive kuyancipha ngokukhawuleza, ngoko ke umsebenzi womgca we-shunt unomda othile;Ukukhethwa kwecandelo, kodwa ekutshintsheni umgca we-shunt utshintshe icandelo lemodeli, ukuba umehluko phakathi kwamacandelo amabini mkhulu, okwangoku kuya kuhanjiswa kwikhebula le-OPGW, eliya kubangela ukuba i-current ye-OPGW cable inyuke ngokukhawuleza.Ngoko ke, xa ukhetha icandelo lomnqamlezo womgca we-shunt, ukubala kufuneka kuphindwe.
2. Ukusetyenziswa kweentambo ezimbini ze-OPGW
Kwimizila emide, ngenxa yokuba i-short-circuit current yecandelo lokuphuma kwi-substation inkulu, kufuneka kusetyenziswe i-optical cable ye-OPGW enkulu;kwimigca ekude nesikhululo, kufuneka kusetyenziswe intambo encinci ye-OPGW ye-optical cross-section.Iintlobo ezimbini zemigca ye-shunt kufuneka ziqwalaselwe xa ukhetha iindidi ezimbini zeentambo ze-OPGW.
3. Indlela yokuguqula ngaphantsi komhlaba
Qhagamshela isixhobo sokumisa i-terminal ye-terminal grid kunye negridi yokumisa i-substation kunye neentsimbi ezininzi ezijikelezayo ezinamacandelwana afanelekileyo, ukwenzela ukuba inxalenye ye-short-circuit current ingene kwi-substation ephantsi komhlaba, enokunciphisa kakhulu umbane wokuvala umgca ongenayo. OPGW intambo yokubona.
4. Indlela ehambelanayo yokukhusela umbane wesekethe ezininzi
Xhuma izixhobo zokumisa iinqaba ezininzi ze-terminal, ukwenzela ukuba i-short-circuit current ingene kwi-substation kunye nemigca yokukhusela umbane we-multi-circuit, ukwenzela ukuba i-current-circuit current iyancipha kakhulu.Ukuba ukuzinza kwe-thermal ye-OPGW yeklasi ye-optical cable yesibini ayithembekanga, isixhobo sokumisa isiseko sesibini senqaba sinokudibaniswa, njalo njalo.Nangona kunjalo, kufuneka kuqatshelwe ukuba ukhuseleko lokulandelelana kwe-zero kufuneka luthathelwe ingqalelo xa udibanisa iinqaba ezininzi.
