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 iintambo ze-optical ezisebenza kwiinkqubo ze-220KV, amandla okuhlala kwindawo yawo yokuxhoma kufuneka alawulwe ukuba angabi ngaphezu kwe-20KV (imigca edibanisa i-double-circuit kunye ne-multi-circuit co-frame 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 ne-multiple loops zibaluleke kakhulu).
2. Ubume bepali kunye nenqaba (kubandakanywa nentloko yenqaba kunye nokuphakama kwetayitile).
3. Ubude bomtya we-insulator (ubude buyahluka ngokwezinga longcoliseko).
4. I-diameter ye-conductor / i-ground wire kunye nokwahlulwa kocingo.
5. Umgama wokhuseleko ukuya kwintambo, umhlaba kunye nezinto eziwelayo.
6. Uxinzelelo / i-sag / ulawulo lwe-span (phantsi komoya, akukho mkhenkce, kunye nobushushu obuphakathi bonyaka, umthwalo awukho mkhulu kune-ES yentambo ye-optical, okanye i-25% RTS; phantsi kweemeko zemozulu zoyilo, umthwalo awukho mkhulu. kunentambo ye-optical MAT ithetha i-40% RTS).
7. I-jumper (i-tension pole tower) kunye ne-grounding body (njengentambo ye-samente) kufuneka ifundwe kwaye impembelelo yabo kufuneka ithathelwe ingqalelo.
2. Ulawulo olunamandla
Ngaphantsi kweemeko eziguquguqukayo, kwi-AT sheathed ADSS cable optical esebenza kwinkqubo ye-220KV, indawo enokubakho yendawo yokuxhoma kufuneka ilawulwe ukuba ingabi ngaphezu kwe-25KV; kwi-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) I-voltage yenkqubo yi-voltage yegama, kwezinye iimeko kuya kubakho impazamo ye- +/- (10～15)%, thatha ukunyamezela okulungileyo;
(2) Umtya wokufakela (ingakumbi umtya ojingayo) kunye ne-pendulum yomoya yentambo 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.
Kufuneka sinikele ingqalelo kwezi kulwakhiwo lweentambo zombane ze-ADSS.
(1) I-corrosion yombane ye-ADSS ye-optical cable sheath phantsi koxinzelelo ngexesha lokusebenza kubangelwa ukuvuza komhlaba ngoku kunye ne-arc yebhanti eyomileyo emalunga ne-0.5-5mA ebangelwa amandla esithuba (okanye amandla ombane ombane) we-capacitive coupling. Ukuba kuthathwe amanyathelo okulawula ukuvuza komhlaba ngoku ngaphantsi kwe-0.3mA kwaye i-arc eqhubekayo ingenziwanga, 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.
5 Iingcingo ze-ADSS ezisetyenziswa kwiinkqubo ze-220KV zithatha i-akhawunti epheleleyo yeemeko zokusebenza ezimileyo kunye neziguquguqukayo. Emva kwexesha, ungaqhubeka nokukhuthaza usetyenziso.
(6) Phantsi kwesiseko sokuqinisekisa umgangatho we-ADSS optical cable, umgangatho woyilo lobunjineli, ulwakhiwo kunye neemeko zokusebenza, ukuthotywa kombane we-ADSS optical cable kunokulawulwa. Kuyacetyiswa ukuba kuqulunqwe kwaye kuphunyezwe izithethe/iinkqubo ezihambelanayo ngokukhawuleza.
