Amapuleti ejoka lensimbi ayizixhumi eziyinhloko emigqeni yokudlulisa amandla, imibhoshongo yokuxhumana, nezakhiwo zensimbi. Ngesikhathi sokusetshenziswa, baxhuma izintambo eziningi ze-insulator, i-hardware, nezingxenye endaweni efanayo yokucindezeleka, okuvumela ukusatshalaliswa komthwalo ofanayo. Ukusetshenziswa kwabo akunakuhlukaniswa nesakhiwo sabo. Ngezansi, sizohlola amapharamitha wokusebenza kwawo:
Idizayini yesakhiwo: Izakhiwo ezijwayelekile zihlanganisa onxande, ama-ellipses, nonxantathu. Ezikhaleni ezithile zokufaka, umumo ongajwayelekile nawo ungenziwa ngendlela oyifisayo. Kusukela ekubukeni, sithole izimbobo eziningi ze-bolt nezimbobo zokukhonkwane, futhi imiphetho iye yayindilinga ukuze kuncishiswe ingozi yokugxila ekucindezelekeni;
Ukukhetha impahla: Lapho sikhetha izinto zokwakha, kufanele sicabangele isimo sokusetshenziswa. Ezimweni ezinemithwalo emincane nendawo eyomile, i-Q235B carbon steel iyakhethwa. Kolayini bakagesi{{3}abaphezulu kagesi kanye nezakhiwo ezinkulu-zensimbi ye-span, i-Q345 low-i-alloy high-insimbi enamandla isetshenziswa, enamandla okukhiqiza aphezulu. Uma isendaweni yasogwini, eswakeme, noma enosawoti, kukhethwa insimbi eshisayo-yediphu ephansi{10}yekhabhoni, enganikeza ukugqwala nokugqwala;
Amandla okuqina: Makhulu noma alingana no-450MPa;
Amandla okukhiqiza: Amakhulu noma alingana no-235MPa;
Ukubekezelela isikhundla somgodi: ± 0.5mm;
Izinga lokushisa elisebenzayo: -40℃~ +120℃.
Lawa amapharamitha ajwayelekile wokusebenza kwamapuleti ejoka ensimbi ngesikhathi sokukhiqiza. Uma izimo zokusebenza zangempela zinezidingo ezihlukile zejoka, ungaxhumana nomkhiqizi ukuze wenze ngokwezifiso imikhiqizo ehlangabezana nezidingo zakho.
Njengohlobo lokufakwa kukagesi, amapuleti ejoka ensimbi asetshenziswa kakhulu embonini yamandla. Ukuze usize abasebenzisi baqonde umkhiqizo ngokuningiliziwe, isifundo esiyisibonelo sephrojekthi yokuvuselela igridi yamandla sinikezwe ngezansi, okufanele futhi kube usizo ekukhetheni amapuleti ejoka ahlukene.
Emaphrojekthini wokuthuthukisa nokuvuselela weGridi Yesifunda, amapuleti ejoka ensimbi asetshenziswa ukuxhuma amakhondatha angawodwana nezintambo zezivikelo. Idizayini yembobo eyisiyingi ivumela ukunwetshwa kokushisa kanye nokufinyela kwamakhondatha, ukugwema ukugxiliswa kwengcindezi. Lobu buchwepheshe semukelwe kabanzi, ikakhulukazi kumagridi kagesi asemaphandleni. Kumaphrojekthi esiteshi esincane esingu-220kV, amapuleti ejoka angunxantathu axhuma izivikeli zamaswishi aphansi kuhlaka lwesiteshi, ezivumelana nezindinganiso ze-EN 50341. Lokhu kuqinisekisa ukuzinza kwesistimu yokumisa phansi yemishini yesiteshi esincane futhi kunikeza izinzuzo ekumelaneni nokugqwala nokusebenza kwemishini.
Ukukhetha ipuleti lejoka lensimbi elifanele lesimo esithile, sidinga ukucabangela izici ezifana nezidingo zomthwalo, indawo yokufaka, nezimo zemvelo. Ngezansi, sizoxoxa ngalokhu ngokuningiliziwe:
Chaza amapharamitha
Chaza ingcindezi ipuleti lejoka elidinga ukuthwala, okuhlanganisa umthwalo omile nomthwalo oguqukayo. Ngemithwalo emincane, khetha okokusebenza kwe-Q235B + isitembu sejoka esingasindi esigxiviziwe. Ngemithwalo emaphakathi engu-110kV-220kV, khetha i-Q345 low alloy material. Ngezimo ezinkulu zomthwalo, kuyadingeka ukwenza ngendlela oyifisayo amapuleti ejoka ajiyile, futhi okubalulekile kufanele kube insimbi yesakhiwo esinengxubevange ephezulu.
Indawo yokulinganisa
Ukuze ugweme izinkinga ezinjengokungakwazi ukufaka noma ukuphoqelela ukuchezuka, ubude nomkhawulo wokwelashwa kwenodi yokulinganisa kufanele kuhambisane nobubanzi bezingxenyekazi zekhompuyutha ezifanayo namaphini. Ububanzi bembobo kufanele bube bukhudlwana ngo-0.5mm-1mm kunobubanzi bebhawodi, futhi imvume kufanele yenzelwe iphutha lokufaka. Ibanga elimaphakathi nembobo kanye nebanga lonqenqema lwembobo kufanele lifane nendandatho elengayo yesivikelo. Uma ibanga lonqenqema lwembobo lilincane kakhulu, lizobangela ukugxiliswa kwengcindezi emaphethelweni. Kunconywa ukuthi ibanga lonqenqema lwembobo libe Likhulu noma lilingane izikhathi ezi-2 ubukhulu bembobo.
Hlola imvelo
Nquma ukuthi izimo zokusebenza zangempela zisezindaweni ezomile,{0}}ezingagqwaliyo{0}ezimaphakathi nezwe, eziswakeme, endaweni egqwala kancane, izimo ezigqwala kakhulu ezifana nesifutho sikasawoti wasogwini, noma izindawo ezibanda kakhulu. Futhi cabangela izimo ezihlukene zaphesheya futhi unqume amazinga ahlukene ngokusekelwe kuzimo ezihlukene ukuze uqinisekise ukuthobelana namazinga emakethe eqondiwe.
Ukulawulwa okuqinile kwenqubo yokukhiqiza kanye nokuhlolwa kwekhwalithi yamapuleti ejoka ensimbi kuqinisekisa amandla esakhiwo. Njengoba sonke sazi, izakhiwo zemishini zinquma ngokuqondile ukuzinza; ngakho-ke, singakwazi ukuqeda izinkinga ezingaba khona ngenqubo nokuhlola:
-Ukuhlolwa kwekhwalithi yenqubo egcwele: ikakhulukazi kuhlanganisa izici zokushintshwa, kusukela kumandla aqinile, amandla esivuno nokuhlolwa kobude ukuze kuqinisekiswe ukuthotshelwa kwezindinganiso ezihambisanayo; ukuhlola -okungonakalisi, njengokuhlola i-ultrasonic yezinto ezifojiwe noma izingxenye ezishiselwe ukuhlola ukuqhekeka kwangaphakathi; ukuhlolwa kwezinhlayiya kazibuthe zezindawo ukuze kutholwe amaphutha angaphezulu; ukuhlolwa kokuvikela ukugqwala; kanye nokuhlolwa kwe-zinc layer nokuhlolwa kokunamathela ukuze kuvinjelwe ukuxebuka kongqimba lwe-zinc;
Ukufakwa okujwayelekile: Qinisekisa ukuthi umthwalo olinganiselwe wepuleti lejoka lensimbi mkhulu noma ulingana nomthwalo osebenzayo × isici sokuphepha. Ukulayisha ngokweqile kunqatshelwe ngokuphelele. Qinisekisa ukuthi amaphuzu okucindezeleka asatshalaliswa ngokulinganayo. Izikhala eziningi zizodala ukushintsha kwengcindezi kanye nokugcwala kwengcindezi yendawo. Ezimweni ezihlukahlukene zokusebenza eziyinkimbinkimbi, kuyadingeka ukuhlanganisa izimo zokusebenza zangempela futhi uthathe izinyathelo zokuvimbela ukuxegiswa.
Amashadi ashisayo: ipuleti yejoka lensimbi, abakhiqizi bepuleti yejoka baseChina, abahlinzeki, imboni
