Ukulawula njani ukubola kombane we-ADSS optical cable?
Njengoko sisazi, zonke iimpazamo zombane zenzeke kwindawo yobude obusebenzayo, ngoko ke uluhlu oluza kulawulwa lugxininiswe kwindawo yobude obusebenzayo.
1. ulawulo olungatshintshiyo:
Ngaphantsi kweemeko ezimileyo, kwi-AT sheathed ADSS optical cable esebenza kwinkqubo ye-220KV, amandla omhlaba wendawo yokuxhoma kufuneka ilawulwe kungabi ngaphezu kwe-20KV (imigca ye-co-frame ephindwe kabini kunye neesekethe ezininzi kufuneka ibe ngaphantsi);ukusebenza kwiinkqubo ze-110KV nangaphantsi Kwintambo ye-PE sheathed ADSS optical cable, amandla omhlaba wendawo yokuxhoma kufuneka ilawulwe ukuba abe ngaphantsi kwe-8KV.Uyilo olunokubakho lwesithuba sokuxhoma okumileyo kufuneka luthathele ingqalelo:
(1) I-voltage yenkqubo kunye nokuhlelwa kwesigaba (i-loops ezimbini kunye neelophu ezininzi zibaluleke kakhulu).
(2) Ubume bepali kunye nenqaba (kubandakanya intloko yenqaba kunye nokuphakama okuqhelekileyo).
(3) Ubude bomtya we-insulator (ubude buyahluka ngokwezinga longcoliseko).
(4) Ububanzi bomqhubi / ucingo lomhlaba kunye nokwahlulwa komqhubi.
(5) Umgama wokhuseleko phakathi kocingo kunye nomhlaba kunye nezinto ezinqumlayo.
(6) Uxinzelelo / i-sag / ulawulo lwe-span (phantsi komoya, akukho mkhenkce, kunye nobushushu obuphakathi bonyaka, umthwalo awukho mkhulu kune-ES yentambo ye-optical, eyi-25% RTS; phantsi kweemeko zemozulu zoyilo, umthwalo awukho. inkulu kunentambo yokukhanya IMAT yi-40% RTS).
(7) I-Jumpers (i-tension poles) kunye nemizimba ephantsi komhlaba (njengeentambo ze-samente) kufuneka zifundwe kwaye impembelelo yazo kufuneka ithathelwe ingqalelo.
Ulawulo lwe-2.dynamic:
Ngaphantsi kweemeko eziguquguqukayo, amandla esithuba se-AT sheathed ADSS cable optical esebenza kwinkqubo ye-220KV kufuneka ilawulwe ukuba ingabi ngaphezu kwe-25KV;i-PE sheathed ADSS optical cable esebenza kwinkqubo ye-110KV nangaphantsi, indawo enokwenzeka yendawo yokuxhoma kufuneka ibe yiLawula ukuba ingabi ngaphezu kwe-12KV.Iimeko zeDynamic kufuneka okungenani zithathele ingqalelo:
(1) Umbane wenkqubo ngumbane oqhelekileyo, kwaye phantsi kweemeko ezithile kuya kubakho impazamo ye- +/-(10～15)%, kwaye ukunyamezela okulungileyo kuya kuthathwa;
(2) Umtya wokufakela (ingakumbi umtya ojingayo) kunye nokujiwuziswa ngumoya kwentambo yokukhanya;
(3) Ukunokwenzeka kokutshintshwa kwesigaba sokuqala;
(4) Ukuba nokwenzeka kokusebenza kwesekethe enye yenkqubo yeesekethe ezimbini;
(5) Eyona meko yokudluliselwa kongcoliseko kummandla;
(6) Kusenokubakho imigca emitsha yokuwela kunye nezinto;
(7) Ubume bezicwangciso zikamasipala zokwakha kunye nophuhliso ecaleni kwendlela (inokuthi iphakamise umgangatho);
(8) Ezinye iimeko eziya kuchaphazela intambo yokukhanya.
Ikhumbuza ukuba ezi kufuneka ziqwalaselwe ekwakhiweni kwe-ADSS optical cable wiring.
(1) I-corrosion yombane ye-ADSS ye-optical cable sheath phantsi koxinzelelo ngexesha lokusebenza kubangelwa ukuvuza komhlaba ngoku malunga ne-0.5-5mA kunye ne-arc band eyomileyo ebangelwa amandla esithuba (okanye amandla ombane ombane) ngokusebenzisa i-capacitive coupling.Ukuba amanyathelo athatyathwa ukulawula ukuvuza komhlaba ngoku ngaphantsi kwe-0.3mA kwaye i-arc eqhubekayo ayikwenziwanga, ukubola kombane we-sheath akuyi kwenzeka ngokomgaqo.Eyona ndlela iyinyani kunye nesebenzayo kukulawula ukutsaleka kunye nokubanakho kwendawo yentambo yokukhanya.
(2) Indawo emileyo uyilo olunokubakho lwe-AT okanye i-PE enesheathed intambo yokukhanya ye-ADSS kufuneka ingabi ngaphezu kwe-20KV okanye i-8KV, ngokulandelelanayo, kwaye ingabi ngaphezu kwe-25KV okanye i-12KV phantsi kwezona meko zinzima kakhulu.Intambo yefiber optic inokusebenza ngokukhuselekileyo.
(3) Indawo engatshintshiyo enokubakho yi-20KV (ubukhulu becala yi-220KV inkqubo) okanye i-8KV (ubukhulu becala yi-110KV).I-hardware yokwahlula i-anti-vibration kwi-system ayikho ngaphantsi kwe-(1～3)m okanye i-0.5m, ngokulandelanayo, ukuphucula i-ADSS Enye yemilinganiselo esebenzayo yokuhlwa kombane kwiintambo ze-optical cable.Ngelo xesha, umonakalo we-vibration we-ADSS optical cable kunye nezinye iindlela zokulwa nokunyakaza (ezifana nesando esisebenzayo esichasene ne-vibration) kufuneka sifundwe.
(4) Indawo yofakelo lwentambo ye-optical (edla ngokubizwa ngokuba yindawo yokuxhoma) ayinakumiselwa ngokwamandla ngokusekelwe kwinqanaba le-voltage yenkqubo kunye / okanye umgama ukusuka kumqhubi wesigaba.Ithuba lendawo yendawo yokuxhoma kufuneka ibalwe ngokwemiqathango ethile yohlobo ngalunye lwenqaba.
5Iingcingo ze-ADSS ezisetyenziswa kwiinkqubo ze-220KV zithatha i-akhawunti epheleleyo yeemeko zokusebenza ezimileyo kunye neziguquguqukayo.Emva kwexesha, ungaqhubeka nokukhuthaza usetyenziso.
(6) Kwindawo yokuqinisekisa umgangatho we-ADSS optical cable, umgangatho woyilo lobunjineli, ulwakhiwo kunye neemeko zokusebenza, kunye nokuthotywa kombane we-ADSS optical cable inokulawulwa.Kucetyiswa ukuba kuqulunqwe kwaye kuphunyezwe izithethe/iinkqubo ezihambelanayo ngokukhawuleza.
