Iipleyiti zedyokhwe zentsimbi ziziqhagamshelo ezingundoqo kwimigca yokuhambisa amandla, iinqaba zonxibelelwano, kunye nezakhiwo zentsimbi. Ngethuba lokusetyenziswa, badibanisa iintambo ezininzi ze-insulator, i-hardware, kunye namacandelo kwinqanaba elifanayo loxinzelelo, okwenza kube lula ukusabalalisa umthwalo ofanayo. Ukusetyenziswa kwabo akunakwahlulwa kwisakhiwo sabo. Ngezantsi, siza kuphonononga iiparamitha zabo zokusebenza:
Uyilo lwesakhiwo: Izakhiwo eziqhelekileyo ziquka ooxande, iiellipses, kunye nonxantathu. Kwizithuba ezithile zokufakela, iimilo ezingaqhelekanga zinokuthi zenziwe ngokwezifiso. Ukususela ekubonakaleni, sifumene imingxuma emininzi ye-bolt kunye nemingxuma yepini, kwaye imiphetho iye yajikeleza ukunciphisa umngcipheko wokuxinzelela uxinzelelo;
Ukukhetha izinto eziphathekayo: Xa ukhetha imathiriyeli, kufuneka siqwalasele imeko yokusetyenziswa. Kwiimeko ezinemithwalo emincinci kunye neendawo ezomileyo, i-Q235B carbon steel ikhethwayo. Kwiintambo zothumelo {{3}eziphezulu zevoltage kunye-nezakhiwo ezinkulu zentsimbi, i-Q345 ephantsi{6}}i-alloy ephezulu{7}}intsimbi yokuqina isetyenziswa, enamandla esivuno esiphezulu. Ukuba ikwimo engaselunxwemeni, efumileyo, okanye enetyuwa, kushushu -kudipha iigalvanized low{10}intsimbi yekhabhoni ekhethiweyo, enokuthi inike umhlwa kunye nothintelo lomhlwa;
Amandla okuqina: Makhulu okanye alingana ne-450MPa;
Amandla esivuno: Makhulu kuno okanye alingana ne 235MPa;
Ukunyamezela isikhundla somngxuma: ± 0.5mm;
Ubushushu obusebenzayo: -40℃~ +120℃.
Le yimilinganiselo yokusebenza esemgangathweni yeeplate zejoka zensimbi ngexesha lemveliso. Ukuba iimeko zokusebenza zangempela zineemfuno ezizodwa zedyokhwe, unokunxibelelana nomenzi ukwenza iimveliso ezihlangabezana neemfuno zakho.
Njengohlobo lokufakelwa kombane, iipleyiti zedyokhwe zentsimbi zisetyenziswa kakhulu kwishishini lamandla. Ukunceda abasebenzisi baqonde imveliso ngokweenkcukacha ezithe vetshe, uphononongo lwemeko yeprojekthi yokulungiswa kwegridi yamandla inikwe ngezantsi, ekufuneka nayo ibe luncedo ekukhetheni iiplate zejoka ezahlukeneyo.
Kwiiprojekthi zokuphucula kunye nokulungiswa kweGridi kaRhulumente, iiplate zejoka zensimbi zisetyenziselwa ukudibanisa abaqhubi ababodwa kwiintambo ze-insulator. Uyilo lomngxuma ojikelezayo luvumela ukwandiswa kwe-thermal kunye nokunciphisa abaqhubi, ukuphepha ukuxinzelela uxinzelelo. Le teknoloji yamkelwe ngokubanzi, ngakumbi kwiigridi zamandla zasemaphandleni. Kwiiprojekthi ze-220kV substation, iipleyiti zedyokhwe ezinxantathu zidibanisa ii-insulators zokutshintshela phantsi kwisakhelo sesikhululo, ngokuhambelana nemigangatho ye-EN 50341. Oku kuqinisekisa ukuzinza kwenkqubo yokumisa izixhobo ze-substation kunye nokubonelela ngeenzuzo ekuxhathiseni ukubola kunye nokusebenza komatshini.
Ukukhetha ipleyiti yedyokhwe yentsimbi efanelekileyo kwimeko ethile, kufuneka siqwalasele izinto ezifana neemfuno zomthwalo, indawo yofakelo, kunye neemeko zokusingqongileyo. Ngezantsi, siza kuxoxa ngoku banzi:
Chaza iiparamitha
Chaza uxinzelelo ekufuneka ipleyiti yedyokhwe ithwale, kubandakanywa umthwalo omileyo kunye nomthwalo oguqukayo. Kwimithwalo emincinci, khetha imathiriyeli ye-Q235B + isitampu seplate yedyokhwe ekhaphukhaphu. Kumthwalo ophakathi we-110kV{8}}220kV, khetha i-Q345 imathiriyeli ye-alloy ephantsi. Kwiimeko ezinkulu zomthwalo, kuyafuneka ukuba wenze ngokwezifiso iipleyiti zedyokhwe ezityebileyo, kwaye izinto kufuneka zibe yintsimbi yolwakhiwo lwamandla aphezulu.
Indawo yokulinganisa
Ukuze ugweme iingxaki ezinjengokungakwazi ukufaka okanye ukunyanzeliswa kokuphambuka, ubude kunye nobude bonyango lwe-node yokulinganisa kufuneka buhambelane nobubanzi beebholiti ze-hardware ezihambelanayo kunye nezikhonkwane. Idayamitha yomngxuma kufuneka ibe yi-0.5mm-1mm enkulu kunobubanzi bebholiti, kwaye kufuneka kwenziwe isibonelelo ngempazamo yokufakela. Umgama ophakathi komngxuma kunye nomgama osekupheleni komngxuma kufuneka uhambelane neringi yokuxhoma isigqubuthelo. Ukuba umgama womgca womngxuma umncinci kakhulu, uya kubangela uxinzelelo lwengqondo. Kucetyiswa ukuba umgama womgca womngxuma ube Mkhulu okanye ulingane namaxesha ama-2 ubukhulu bomngxuma.
Vavanya okusingqongileyo
Qinisekisa ukuba ezona meko zokusebenza zikwindawo eyomileyo,{0}}engadlekiyo phakathi kwelizwe, kwindawo efumileyo, enomhlwa kancinci, iimeko ezinokonakalisa kakhulu ezifana nesitshizi setyuwa elunxwemeni, okanye iindawo ezibanda kakhulu. Kwakhona qwalasela iimeko ezahlukeneyo zaphesheya kwaye umisele imigangatho eyahlukeneyo ngokusekwe kwiimeko ezahlukeneyo zokuqinisekisa ukuthotyelwa kwemigangatho yemarike ekujoliswe kuyo.
Ukulawulwa kwenkqubo yokuvelisa ngokungqongqo kunye nokuhlolwa komgangatho weepleyiti zejoka zensimbi ziqinisekisa amandla okwakhiwa. Njengoko sonke siyazi, iipropati zomatshini zinquma ngokuthe ngqo ukuzinza; ke ngoko, singakwazi ukuphelisa iingxaki ezinokwenzeka ngenkqubo kunye nokuhlola:
Ukuhlolwa komgangatho -ogcweleyo wenkqubo: ikakhulu ibandakanya iimpawu zoomatshini, ukusuka kumandla okuqina, amandla esivuno kunye novavanyo lokwandisa ukuqinisekisa ukuthotyelwa kwemigangatho ehambelanayo;-uvavanyo olungonakalisi, olufana novavanyo lwe-ultrasonic lwe-forging okanye iindawo ezidityanisiweyo ukujonga iintanda zangaphakathi; ukuvavanywa kwamasuntswana omhlaba ukuze kubonwe iziphene zomhlaba; uvavanyo lokukhusela umhlwa; kunye nobukhulu be-zinc layer kunye novavanyo lokubambelela ukukhusela i-zinc layer peeling;
Ukufakwa okusemgangathweni: Qinisekisa ukuba umthwalo olinganisiweyo wesitya sejoka yensimbi mkhulu okanye ulingana nomthwalo osebenzayo × ukhuseleko. Ukulayisha ngaphezulu kuthintelwe ngokungqongqo. Qinisekisa ukuba iindawo zoxinzelelo zisasazwa ngokulinganayo. Izikhewu ezigqithisileyo ziya kubangela ukutshintshwa koxinzelelo kunye nokugqithiswa koxinzelelo lwendawo. Kwiimeko ezahlukeneyo zokusebenza eziyinkimbinkimbi, kuyimfuneko ukudibanisa iimeko zangempela zokusebenza kunye nokuthatha amanyathelo okukhusela ukukhulula.
Iifayile ezishisayo: ipleyiti yedyokhwe yentsimbi, abenzi beepleyiti zentsimbi yaseTshayina, ababoneleli, umzi-mveliso
