Izesekeli Zekhebula Ezingu-35kV Nangaphansi Kwe-Medium Voltage

Izesekeli zekhebula lohlobo lokuphonsa zisebenzisa izinto ze-thermosetting resin, ezifakwe endaweni yokubumba noma emzimbeni webhokisi ekugcineni kwekhebula noma ijoyinti ngemva kokwelashwa, futhi izesekeli zekhebula zakhiwa ngemva kokulungiswa. Zifaneleka kakhulu ekuxhumeni izintambo ezifakwe epulasitikini ezifakwe epulasitikini kanye nezintambo ezifakwe ephepheni ezifakwe ephepheni.

Izixhumi ezihlukaniswayovumela izintambo kanye neminye imishini kanye nezintambo ukuthi zixhume noma zinqamule izesekeli zekhebula ezivikelwe ngokuphelele, njengeziphetho, amajoyinti, kanye namajoyinti amagatsha. Izinto eziyinhloko ezisetshenziswayoizixhumi ezihlukanisiweamakhabethe okushintsha avaliwe ngokuphelele, i-RMU, amabhokisi egatsha lekhebula kanye neminye imishini, engabhekwa njengohlobo olusha lwetheminali yekhebula. Futhi okunye kusebenzisa isakhiwo setheminali esetshenziselwe kusengaphambili.

Akunzima ukubona kusukela ekuhlukanisweni komkhiqizo wezinsiza zekhebula okukhulunywe ngakho ngenhla ukuthi ubuchwepheshe bokuhlela kusengaphambili kanye nobuchwepheshe bokunciphisa okubandayo obungenza kube lula izidingo zokufakwa endaweni sebuvele buthathe indawo ebalulekile ekuthuthukisweni kwezinsiza zekhebula.

Ukusetshenziswa kobuchwepheshe obusha emikhiqizweni yezesekeli zekhebula:

Izidingo zobuchwepheshe eziyisisekelo zokuxhumeka komqhubi nokuxhumeka komqhubi yilezi: ukuxhumana okuhle komqhubi: kwetheminali, umongo wokuhambisa ikhebula, induku yokuphuma, kanye netheminali kumele kuxhunywe kahle; kwejoyinti eliphakathi, umqhubi wekhebula kanye nepayipi lokuxhuma kumele kuxhunywe kahle. Okusho ukuthi, ukumelana kokuxhumana kwendawo yokuxhuma kuyadingeka kube kuncane futhi kuzinzile. Uma kuqhathaniswa nokumelana kwezintambo ezinobude obufanayo kanye nesigaba esifanayo, isilinganiso sezintambo ezisanda kufakwa akufanele sibe ngaphezu kuka-1.

Njengamanje, ubuchwepheshe bokugoqa busetshenziswa kakhulu endaweni, okudinga imishini ethile yobungcweti. Ngobuchwepheshe bokuxhuma i-bolt, kudingeka i-torque wrench kuphela ngesikhathi sokwakhiwa endaweni ukuze kuhlangatshezwane nezidingo zobuchwepheshe eziyisisekelo zokuxhuma i-conductor. Lokhu kwenza kube lula izidingo zobungcweti zemishini yokufaka. Futhi ngokuxhumeka kwekhebula le-aluminium okudingeka kususwe ungqimba lwe-oxide olungenawo ugesi, asikho isidingo sokwenza ukwelashwa okukhethekile kokususa ugesi kusengaphambili.

Izinto zokuvala umoya Izinto zerabha ze-EPDM zerabha kanye nerabha ye-silicone zisetshenziswe kabanzi kwizesekeli zekhebula ezenziwe kusengaphambili. Emkhakheni wezesekeli zekhebula ezine-voltage ephezulu, uma kuqhathaniswa, zingahlukaniswa ngesakhiwo saseYurophu ngerabha ye-silicone njengezinto eziyisisekelo kanye nesakhiwo sesitayela saseJapane se-EPDM esinerabha ye-acrylic njengezinto eziyisisekelo. Emkhakheni we-voltage ephakathi, izesekeli zekhebula zerabha ze-EPDM ezithuthukisiwe zinamandla angcono okusebenza kanye nokumelana nokudabuka kunemikhiqizo yerabha ye-silicone efanayo.

Ubuchwepheshe bangaphambi kokwandiswa endaweni buyindlela yokufaka imikhiqizo yezinsiza zekhebula ezincibilika kalula, okungukuthi, emahoreni ambalwa ngaphambi kokufakwa, amalunga ancibilika kalula ancibilika kusengaphambili endaweni ngamathuluzi alula alahlwayo. Bugwema ukulahlekelwa ukusebenza okuyingxenye kwemikhiqizo evamile encibilika kalula ngesikhathi sokuthuthwa kanye nokugcinwa kwesikhathi eside, ngaleyo ndlela buhlinzeka ngokucindezela kwe-radial okuqhubekayo, okuhlala isikhathi eside futhi okuthembekile. Kufanelekile ikakhulukazi njengezingxenye ezisele zesistimu. Ngamafuphi, ukuze kube lula ukufakwa endaweni futhi kuqinisekiswe ikhwalithi yokufaka, kunciphisa izidingo eziningi ezingeni lobuchwepheshe labafaki endaweni. Ukwakhiwa kusengaphambili kanye nokwenza lula kuzoba yisiqondiso esiyinhloko sokuthuthukiswa kobuchwepheshe bezinsiza zekhebula esikhathini esizayo. Ukwakhiwa kusengaphambili kwemikhiqizo kungahlolwa ngaphambi kokushiya ifektri.

Izesekeli zekhebula ezincibilika kalula zizoba yinto eyinhloko endaweni, ngaleyo ndlela ziqinisekise ukusebenza okuphephile nokuthembekile kohlelo lwamandla, futhi zifeze inhlanganisela engcono kakhulu yobuchwepheshe kanye nomnotho.
