Namhlanje, ikakhulu sabelanaNtlanuamanyathelo okuphucula ukuxhathisa kombane kwiintambo ze-ADSS optical.
(1) Ukuphuculwa kokulandelela umkhondo we-cable optical sheath
Ukuveliswa kokubola kombane kumphezulu wentambo ye-optical kuxhomekeke kwiimeko ezintathu, enye yazo ibaluleke kakhulu, oko kukuthi, intsimi yombane, ukufuma kunye nomhlaba ongcolileyo.Ngoko ke, kucetyiswa ukuba zonke iintambo ze-OPGW optical zisetyenziswe kwi-110kV esanda kwakhiwa nangaphezulu kweentambo zothumelo;iilayini ezingaphantsi kwe-110kV zisebenzisa iintambo ze-ADSS ezine-anti-track AT sheath.
(2) Ukuphucula uyilo kunye nokuveliswa kweentambo zokukhanya
Ukuze kuphuculwe ngakumbi ukusebenza kokhuseleko lwentambo yokukhanya ye-ADSS kumgca wothumelo, kunokuqwalaselwa ukunciphisa i-sag ye-ADSS optical cable erection, oko kukuthi, ukunyusa amandla e-tensile ye-ADSS optical cable ngelixa unciphisa ukuhamba kwayo. ixabiso.Xa phantsi kweemeko ezinzima ezifana nomoya onamandla kunye nesanti, ukukhahlela kunye nokwandiswa kwentambo ye-optical akuyi kubangelwa yimpembelelo yomoya, eya kunciphisa umgama wokhuseleko phakathi kwayo kunye nomgca wokuhambisa kwaye kubangele ukubola kombane.
Kuyilo lwentambo ye-optical, kugxininiswa iinkalo ezintathu:
1. Ukwandisa umsonto we-aramid ukunciphisa i-sag ye-ADSS yentambo yokukhanya;
2. Ukusebenzisa i-modulus ephezulu kunye namandla aphezulu i-aramid fiber esanda kuphandwa yi-DuPont, i-modulus yayo i-5% ephezulu kune-fiber ye-aramid eqhelekileyo, kwaye amandla ayo amalunga ne-20% aphezulu kunalawo e-aramid fiber eqhelekileyo, enciphisa ngakumbi i-creep of aramid fiber. Intambo yokukhanya ye-ADSS;
3. Ukwandisa ubukhulu be-sheath ye-anti-tracking sheath ukusuka kwi-1.7mm yesiqhelo ukuya ngaphezu kwe-2.0mm, kwaye kwangaxeshanye uqinisekise ukuqina kunye nokugudiswa phakathi kweemolekyuli ze-optical cable extruded sheath kwimveliso yokuphucula ukuxhatshazwa kombane. yentambo yokukhanya.
(3) Khetha indawo efanelekileyo yokuxhoma intambo yentambo
Ukukhetha indawo efanelekileyo yokuxhoma intambo ye-optical inokunciphisa ngokufanelekileyo ukwenzeka kwe-corrosion yombane.
Ukuba akukho ndawo yokuxhoma efanelekileyo kumgca okanye indawo yokuxhoma kufuneka ibe phezulu ngenxa yezizathu ezikhethekileyo, amanyathelo athile okulungisa kufuneka athathwe.Amanyathelo okulungisa acetyiswayo anokuthathwa ngolu hlobo lulandelayo: ①Yongeza ishidi lentsimbi okanye intsimbi yentsimbi njengekhaka kufutshane nesiphelo sezixhobo zocingo ezijijelweyo, ezinokuphucula kakhulu ukuhanjiswa okufanayo kwendawo yombane kunye nokunciphisa amathuba okuphuma kwecorona: ②Intambo yokubona kufutshane nendawo Sebenzisa iteyiphu yokugquma i-arc-resistant ukusonga umphezulu ukulawula ukwenzeka okuphindaphindiweyo kwee-arcs;③Sasaza ipeyinti yokugquma ye-silicone engeyomda kumphezulu wentambo yokukhanya kufutshane nendawo.Umsebenzi wepeyinti ye-insulating kukutshintsha kancinci intsimi yombane kwindawo yokugquma ukunciphisa ukuba nokwenzeka kwe-corona kunye ne-flashover yongcoliseko.
(4) Ukuphucula indlela yokufakela izixhobo kunye ne-absorber shock
Ukuphucula indlela yokufakela izixhobo kunye ne-shock absorbers kunokuphucula indawo yombane ye-induction kufuphi nezixhobo kunye nokunciphisa ukwenzeka kombane wombane.Fakela iringi yokunqanda i-corona kwisilinganisi esimalunga ne-400mm ukusuka ekupheleni kocingo oluxineneyo olungaphakathi, uze ufakele into ekwaziyo ukuvalela ukothuka kwe-spiral malunga ne-1000mm ukusuka ekupheleni kweringi yokulwa ne-corona.Ngaphantsi kwamandla ombane anyanzelweyo we-15-25kV, umgama phakathi kweringi yokuchasana nokulinganisa kunye ne-spiral shock absorber kufuneka ugcinwe ngaphezu kwe-2500mm ukunciphisa ukwenzeka kokuhlwa kombane kwindawo yoqhagamshelwano eqinileyo yentambo ye-ADSS kunye ne-spiral shock absorber. .Inani le-spiral shock absorbers elisetyenzisiweyo limiselwa yipitch yomgca.
Ngale ndlela yofakelo iphuculweyo, umsesane ochasene ne-corona unokuphucula kakhulu imeko yebala lombane ekupheleni kofakelo locingo olujijekileyo, kwaye inokonyusa umbane we-corona ngaphezulu kwexesha elinye.Ngelo xesha, i-anti-tracking spiral shock absorber inokuthintela ukubola kombane we-shock absorber.Umonakalo kwintambo yefiber optic.
(5) Ukunciphisa umonakalo kwi-sheath yekhebula ngexesha lokwakha
Ekufakeni i-rack cable optical, kucetyiswa ukuba xa ukhetha ukufakwa kwentambo ye-optical, abavelisi be-hardware kufuneka bafune ngokungqongqo ukulungelelanisa i-diameter yangaphandle ye-ADSS optical cable, ukuze kuqinisekiswe ukuba emva kofakelo, umsantsa phakathi kweentambo ze-Optical cable. ukufakwa kunye nekhebula le-optical liyancipha, kwaye ityuwa iyancitshiswa.Uthuthu lungena kumthungo phakathi kwezixhobo zocingo eziphothiweyo kunye nentambo yokukhanya.Ngexesha elifanayo, kwi-hardware ye-tensile, i-hardware ye-drape, i-wire wire, njl.Isiphelo socingo olujijekileyo kufuneka sibe phantsi sithe tyaba xa abasebenzi bokwakha besebenza ukukhusela umonakalo kwishethi yekhebula.La manyathelo anokunciphisa ukuqokelela kunye nokuzala kothuli olungcolileyo kwiindawo eziqhekekileyo zokufakelwa kunye nesikhumba esiphukileyo phezu kwentambo ye-optical, kunye nokunciphisa ukunyanzeliswa kwe-corrosion yombane.
