Iindaba

Eli phepha lichaza ubukhulu becala ubume bomgca ophezulu, ukukhethwa kweemfuno zecandelo ngalinye, indawo eqhuba umgca kunye nokubala komgca kunye nokudibanisa kweemeko zemeteorological, iinkqubo zokuyila umgca ophezulu.Qonda iiparitha eziphambili zomatshini kunye nezinto ezibonakalayo zocingo;Impembelelo yomatshini yeemeko zemeteorological kubaqhubi kunye nokwakheka kweemeko ezidibeneyo zemozulu, kunye nokuqonda ukuhamba okusisiseko koyilo lwesekethe.

Ukuhlelwa kunye nokwakhiwa kweentambo zothumelo oluphezulu
1. Ukuhlelwa kweentambo zothumelo
Intambo yamandla iyinxalenye ebalulekileyo yenkqubo yamandla, enoxanduva lokusasaza nokusasazwa kwamandla ombane.Imigca ehambisa amandla ombane ukusuka kumthombo ukuya kwiziko lomthwalo wombane kuthiwa ziintambo zothumelo.Ukuze kuncitshiswe ilahleko yamandla ombane kwinkqubo yothumelo, iintambo zothumelo zamkele amanqanaba ombane ahlukeneyo ngokomgama wothumelo kunye nomthamo wothumelo.Okwangoku, amanqanaba ombane ahlukeneyo asetyenziswa e-China yi-35, 60, 110, 220, 330, 500kV, njl njl. E-China, umgca we-35 ~ 220kV ubizwa ngokuba ngumgca wokuhanjiswa kwamandla aphezulu, kwaye umgca we-330 ~ 500kV ubizwa ngokuba intambo yothumelo lwamandla ombane aphezulu.Ukongezelela, umgca ojongene nomsebenzi wokusabalalisa umbane ubizwa ngokuba ngumgca wokusabalalisa.Amanqanaba ombane emigca yokusasaza yaseTshayina ngala: 380V/220V, 6KV, 10KV, ebhekisa kwimigca engaphantsi kwe-1kV njengemigca yokuhambisa i-voltage ephantsi, i-1 ~ 10KV imigca njengemigca yokuhambisa i-voltage ephezulu.
Imigca yokudlulisa inokuthi ihlulwe ibe yimigca yentambo kunye nemigca ephezulu ngokwesakhiwo sabo.Xa kuthelekiswa nomgca wekhebula, umgca we-overhead uneenzuzo ezininzi ezicacileyo, ezifana nesakhiwo esilula, ixesha elifutshane lokwakha, ixabiso eliphantsi lokwakha, ukugcinwa okufanelekileyo, ukusebenza kakuhle kokutshatyalaliswa kobushushu, umthamo omkhulu wokuhambisa kunye nokunye.Eli phepha lazisa kuphela ulwazi olusisiseko lweentambo zothumelo lwamandla ombane aphezulu.
2. Ulwakhiwo lweentambo zothumelo ezihamba phezulu
Iintambo zothumelo zidla ngokusetyenziselwa ukuqhagamshela oomatshini bombane bengingqi kunye nezikhululo ezincinci kwicala lokufumana.Ukugcina umgama othile phakathi kweengcingo eziphilayo zomgca wokuhambisa amandla kunye nomhlaba, sebenzisa izibonda kunye neenqaba zokuxhasa iingcingo, njengoko kuboniswe kuMzobo 1-1.Umgama othe tye phakathi kwemigca esembindini yeenqaba ezimeleneyo ubizwa ngokuba ngumgama wegiya.Icandelo loxinzelelo lwenziwa yimigama emininzi phakathi kweenqaba ezimbini ezimeleneyo.Njengoko kubonisiwe kuMfanekiso #5 ~ #9, icandelo loxinzelelo liqulunqwe yimigama emine.Ukuba kukho umgama omnye kuphela kwicandelo loxinzelelo, ubizwa ngokuba wodwa, njengoko kubonisiwe kumfanekiso ophakathi kwenqaba #9 kunye nenqaba #10.Umgca wothumelo uhlala uqulunqwe ngamacandelo amaninzi e-tensioning, kubandakanywa amacandelo ahlukeneyo.

Amanye amagama anxulumene nemigca ephezulu
Okokuqala, amanye amagama asisiseko anxulumene nesakhiwo somgca ongaphezulu achazwe ngolu hlobo lulandelayo:
(1) Umgama weGear - Umgama othe tye phakathi kweendawo zokunqunyanyiswa kweengcingo kwiinqaba ezimbini ezikufutshane ubizwa ngokuba ngumgama wegiya, odla ngokubonakaliswa, njengoko kuboniswe kuMfanekiso 1-2.
(2) i-sag (ukuphumla) - umgama phakathi kwayo nayiphi na indawo yocingo kunye nendawo yokunqunyanyiswa kwindlela echanekileyo ibizwa ngokuba yi-sag, ebizwa ngokuba yi-relaxation.
Ngokuqhelekileyo, i-sag ibhekisela kwi-sag ephezulu kwi-gear enye ngaphandle kokuba kuchazwe ngenye indlela, kwaye idla ngokuboniswa ngunobumba F, njengoko kubonisiwe kwi-Figure 1-2.Xa indawo yokumisa ucingo ilingana (ukuphakama kuyalingana), i-sag ephezulu kumgama wegiya embindini;Xa indawo yokumisa ucingo ingalingani nobude (ukuphakama akulingani), ubuninzi be-sag kwi-gear bumalunga nombindi womgama wegiya.

(3) Umda - Umgama omncinci ovumelekileyo phakathi kocingo kunye nomhlaba ubizwa ngokuba ngumda, njengoko kuboniswe nguH kuMfanekiso 1-2.Ixabiso lokunciphisa umgama lichazwe ngokweenkcukacha kwimimiselo yobugcisa yoyilo lwemigca yokuhambisa i-Overhead kunye neMithetho yoBugcisa yoyilo lwemigca yokuhambisa ngaphezulu ekhutshwe nguMphathiswa woMbane welizwe lethu.Awona macandelo aphambili omgca wothumelo ongaphezulu ngumqhubi, umqhubi wombane, i-insulator, inqaba, intambo kunye nesiseko.

Amacandelo eentambo zothumelo oluphezulu

Sinika inkcazo emfutshane yemisebenzi esisiseko kunye neentlobo zamacandelo eesekethe eziphezulu.

1, umqhubi

Iingcingo zisetyenziselwa ukuphatha umsinga wombane kunye namandla ombane.Ngokubanzi, iintambo zothumelo zisebenzisa i-conductor enye kwisigaba ngasinye, kodwa kwi-ultra-voltage ephezulu kunye nemigca yokuhambisa umthamo omkhulu, ukuze kuncitshiswe i-corona yokunciphisa ilahleko yamandla kunye nokunciphisa ukuphazamiseka koonomathotholo kunye ne-TEVISION, ii-conductor zokwahlulwa kwesigaba zisetyenziswa kakhulu, oko kukuthi, ezimbini. , iingcingo ezintathu, ezine okanye ngaphezulu (ezidla ngokulungiswa kwindandatho) zisetyenziswa.

2. Umqhubi wombane kunye nomzimba osezantsi

I-conductor yombane ixhonywe phezulu kwi-pali tower, kwaye idibaniswe nomzimba wokumisa ngocingo olusezantsi kwi-pali nganye yesiseko.Xa ukukhutshwa kwelifu elikhanyayo kubetha umgca wombane, umqhubi wombane ubekwe ngaphezu kwe-conductor, kunye nombane okhoyo phezu komhlaba ukhutshelwa emhlabeni.Ngale ndlela, amathuba okuba nombane obetha umqhubi uyancitshiswa, ukugquma komgca kukhuselwe emonakalweni wombane ogqithisayo, kwaye ukukhuselwa kombane kunikezelwe ukuqinisekisa ukusebenza ngokukhuselekileyo komgca.Kuphela ngaphezulu kwe-110kV umgca webakala lombane oqhelekileyo usetwa, izinto zayo zihlala zingumtya wentsimbi.

3, inqaba

Inqaba yesibonda isetyenziselwa ukuxhasa umqhubi kunye nomqhubi wombane kunye nezixhobo zayo, kunye nokugcina umgama othile okhuselekileyo phakathi komqhubi, umqhubi wombane kunye nenqaba, kunye naphakathi komqhubi kunye nomhlaba kunye nezinto eziwelayo okanye ezinye izakhiwo. .

4. I-Insulators kunye neentambo zokugquma

I-insulators yizona nxalenye eziphambili ze-insulation line, ezisetyenziselwa ukuxhasa okanye ukumisa ucingo ukuze lufake kwinqaba kunye nokuqinisekisa ukuba umgca unamandla ombane othembekileyo.Ngenxa yokuba ayixhomekeke kuphela kumandla omatshini kunye nesenzo sombane, kodwa kunye nokumelana nokukhukuliseka kweegesi ezinobungozi emoyeni.

Ke ngoko, kuyafuneka ukuba ube namandla aneleyo omatshini, inqanaba lokufakwa kwe-insulation kunye nokumelana ne-corrosion.

5, hardware

Izixhobo zokuhambisa intambo zidlala indima yokuxhasa, ukulungisa kunye nokudibanisa iingcingo zokukhusela kunye neengcingo zokukhusela umbane kwiintambo zokuhambisa ngaphezulu.Kwaye inokwenza i-wiring iqine.Kukho iintlobo ezininzi zokufakelwa kwegolide, ezinokuthi zohlulwe zibe ziindidi ezintlanu: i-wire clamp, ikhonkco, ukhuseleko kunye nomzobo wocingo ngokweempawu kunye nokusetyenziswa kwazo.

Isiseko se-Pole tower sigxininiswe emhlabeni ukuze kuqinisekiswe ukuba i-pole tower ayithambeki, idilike, ithobeke kunye nezinye izibonelelo.Ukuba intonga yekhonkrithi eyomeleziweyo ingcwatywe ngokuthe ngqo emhlabeni, ngenxa yokuba indawo enqamlekileyo yesibonda incinci, isibonda siya kutshona kumhlaba jikelele.Ngeli xesha ukuthintela ukutshona kwepali, ngokufuthi ezantsi kwepali umqamelo indawo enkulu yepleyiti eqinisiweyo yekhonkrithi - i-chassis, i-chassis kukuthintela isiseko sokuzika kwepali.Ngakolunye uhlangothi, umsebenzi wekhebula kukuphucula amandla enqaba, ukuthwala umthwalo wangaphandle kwinqaba yenqaba, ukwenzela ukunciphisa ukusetyenziswa kwezinto eziphathekayo kwinqaba;Ngakolunye uhlangothi, kunye nentonga yocingo kunye ne-wire tray, ukulungisa inqaba phantsi, ukuqinisekisa ukuba inqaba ayifuni, iwa.Isiseko seTower ngokweendawo ezahlukeneyo, i-geology kunye neemeko zokwakha, uhlobo olusetyenzisiweyo lwahlukile.
