Isingeniso
Amadivayisi okusiza ingcindezi (PRDs)ziyisivikelo sokugcina se-transformer uma kwenzeka iphutha elikhulu likagesi ngaphakathi kwe-transformer. Njengoba ama-PRD enzelwe ukudambisa ingcindezi ngaphakathi kwethangi le-transformer, awabalulekile kuma-transformer angenawo ithangi.
Inhloso yama-PRDs
Ngesikhathi sephutha elikhulu likagesi, kuzokwenziwa i-arc yokushisa ephezulu futhi le arc izodala ukubola nokuhwamuka koketshezi oluzungezile oluvikelayo. Lokhu kwenyuka okungazelelwe kwevolumu ngaphakathi kwethangi le-transformer kuzophinde kudale ukwanda okungazelelwe kwengcindezi yethangi. Ukucindezela kufanele kuncishiswe ukuze kuvinjelwe ukugqashuka kwethangi okungenzeka. Ama-PRD avumela ukucindezela ukuba kukhululwe. Ama-PRD ngokuvamile ahlukaniswa abe izinhlobo ezimbili, ama-PRD avulekayo abese evala nama-PRD avulekayo futhi ahlale evulekile. Ngokuvamile, uhlobo lokuvala kabusha lubonakala luthandwa kakhulu emakethe yanamuhla.
Ukuvala kabusha ama-PRD
Ukwakhiwa kwe-transformer PRDs kufana nevalvu yokuphepha elayishwe entwasahlobo ejwayelekile (SRV). Ipuleti elikhulu lensimbi elixhunywe ku-shaft emaphakathi libanjwa livalwe isiphethu. Ukushuba kwentwasahlobo kubalwa ukuthi kunqotshwe ukucindezela okuthile (iphuzu elimisiwe). Uma umfutho wethangi ukhuphuka ngaphezu kwengcindezi ebekiwe ye-PRD, intwasahlobo izocindezelwa futhi ipuleti lizothuthela endaweni evulekile. Ukucindezela kwethangi kukhulu, kukhulu ukucindezelwa kwentwasahlobo. Uma umfutho wethangi usunciphile, ukushuba kwentwasahlobo kuzosusa ngokuzenzakalelayo ipuleti libuyele endaweni evaliwe.
Induku exhunywe kunkomba enombala ngokuvamile yazisa abasebenzi ukuthi i-PRD icushiwe, lokhu kuyasiza ngoba mancane amathuba okuba abasebenzi babe endaweni ngesikhathi sokusebenza. Ngaphandle kwesibonisi sendawo esibukwayo, i-PRD cishe izoxhunywa ohlelweni lokuqapha i-alamu kanye nesekethe ye-transformer tripping.
Kubalulekile ukuthi ingcindezi yokuphakanyiswa kwe-PRD ibalwe ngendlela efanele ukuze kuqinisekiswe ukusebenza kwayo okulungile. Ama-PRD kufanele agcinwe njalo ngonyaka. Ukuhlolwa kwe-PRD ngokuvamile kungenziwa ngesandla.
Uyasijabulela lesi sihloko? Bese uqiniseka ukuthi ubheka Isifundo sethu Sevidiyo Se-Electrical Transformers. Isifundo sinamahora angaphezu kwamabili evidiyo, imibuzo, futhi uzothola isitifiketi sokuqeda lapho uqeda isifundo. Jabulela!
Ama-PRD angavali kabusha
Lolu hlobo lwe-PRD aluthandwa namuhla ngenxa yentuthuko yakamuva yezobuchwepheshe eyenza ukwakheka kwayo kungafuneki. Amadizayini amadala afaka iphinikhodi yokukhulula nokusethwa kwe-diaphragm. Uma kwenzeka kuba nomfutho wethangi ophezulu, iphinikhodi yokusiza yayizophuka futhi umfutho uzokhululeka. I-tank yahlala ivulekile emoyeni kuze kube yilapho i-PRD ishintshwa.
Izikhonkwane zokukhulula zenzelwe ukuphuka ngengcindezi ethile futhi azikwazi ukulungiswa. Iphinikhodi ngayinye ibhalwe ukukhombisa amandla ayo okuphuka kanye nengcindezi yokuphakamisa. Kubalulekile ukuthi iphinikhodi ephukile ifakwe esikhundleni sephinikhodi enezilungiselelo ezifanayo ncamashi nephinikhodi ephukile ngoba ngaphandle kwalokho ukwehluleka okuyinhlekelele kweyunithi kungase kwenzeke (ukuphuka kwethangi kungase kwenzeke ngaphambi kokuthi i-PRD iphakanyiswe).
Amazwana
Ukudweba kwe-PRD kufanele kuqhutshwe ngokucophelela njengoba noma yikuphi ukudweba kwezingxenye zokusebenza kungase kuguqule ukucindezela kokuphakamisa kwe-PRD futhi ngaleyo ndlela kuvuleke kamuva (uma kunjalo).
Impikiswano encane izungeza ama-PRD ngoba abanye ochwepheshe bemboni bakholelwa ukuthi iphutha lizodinga ukuba seduze ne-PRD ukuze i-PRD isebenze ngempumelelo. Iphutha elisuka kude ne-PRD maningi amathuba okuthi liqhume ithangi kunalelo eliseduze ne-PRD. Ngalesi sizathu, ochwepheshe bezimboni baphikisana nokusebenza kweqiniso kwama-PRD.
