Ukulungiswa kwezinga likawoyela we-transformer, indlela yokukhipha ugesi kanye nezinyathelo zokuphepha

Ukuhlukaniswa kwe-Transformer

I-transformer uhlobo lwemishini kagesi yokushintshanisa amandla. Ngokwezakhiwo ezahlukene kanye nemidiya yokupholisa nokuvikela, ingahlukaniswa ngezigaba ezintathu ezilandelayo: ama-transformer kagesi acwiliswe ngamafutha, ama-transformer kagesi afakwe igesi, kanye nama-transformer kagesi ohlobo olomile.

Izimbangela Zezinga Lamafutha Elingavamile Ku-Transformer

Uma izinga likawoyela we-transformer lingahambisani nokushisa kukawoyela, okungukuthi, lingahambisani nomugqa wokushisa, kubhekwa ukuthi izinga likawoyela alijwayelekile. Izinga likawoyela elingajwayelekile libonakala kakhulu njengezinga likawoyela elingamanga kanye nezinga likawoyela eliphansi.

(1) Ukwehluleka kwesikhombisi sezinga likawoyela: hlola futhi ulungise isibonakaliso sezinga likawoyela.

(2) Umshini wokuphefumula uvaliwe, ukuze umoya ungangeni lapho izinga likawoyela lehla, futhi inkomba yezinga likawoyela iphezulu kakhulu: susa umshini wokuphefumula.

(3) Igesi iqoqana ekamelweni likawoyela le-oyili conservator, okwenza izinga likawoyela libe phezulu kunezinga langempela likawoyela: i-oyili conservator kumele igcwaliswe futhi ikhishwe.

(4) Igumbi lamafutha le-oyili conservator alivalwanga kahle (i-diaphragm noma i-capsule iphukile, izimbobo ziqhekekile, njll.), ukuze izinga lamafutha lingene kwi-diaphragm noma i-capsule, futhi izinga lamafutha liphansi: lungisa kabusha i-oyili conservator.

(5) I-transformer ivuza kakhulu, okwenza izinga likawoyela libe phansi: bhekana nendawo yokuvuza bese ugcwalisa uwoyela kabusha.

Izindaba ezidinga ukunakwa ekukhishweni kukawoyela we-transformer

(1) Vula imbobo yomoya ye-oyili conservator noma ithangi likawoyela ukuze uphule indawo yokuhlanza umoya.

(2) Uma uwoyela osethangini lokugcina uwoyela ungadingeki ukukhishwa, ivalvu yebhabhathane yombhobho wegesi ingavalwa, futhi uwoyela osethangini uwoyela kuphela ongakhishwa. (Lapho kushintshwa ingxenye engaphansi kwe-conservator yamafutha, njengomsebenzi wokufaka esikhundleni se-bushing)

(3) Inani lamafutha akhishwayo kufanele libalwe ngokuya ngobubanzi bokugcinwa. (Ukufakwa esikhundleni kwe-bushing, i-valve yokukhulula ingcindezi, i-valve ye-butterfly ye-vacuum, kanye nokulungiswa kwe-transformer iyonke kunezinhlobo ezahlukene zokukhishwa kwamafutha)

(4) Naka izinga lokushisa kanye nomswakama lapho ukhipha uwoyela, futhi ukukhishwa kwawoyela kufanele kwenziwe kumswakama olinganiselwe ongu-≤75%.

Qaphela: Qiniseka ukuthi uvula ipulaki yokuvula umoya ngaphambi kokukhipha uwoyela

Izinyathelo Zokuqapha Zokugcwalisa Amafutha E-Transformer

(1) Umzimba oyinhloko we-transformer kufanele uhlanzwe nge-vacuum ngaphambi kokugcwaliswa kwamafutha amakhulu, futhi kufanele kufakwe ipayipi elixhumanisayo phakathi kwe-tap changer kanye nomzimba oyinhloko ngaphambi kokuhlanza nge-vacuum. (Uma i-gas kanye ne-oyela conservator zingenakukwazi ukukhishwa, i-butterfly valve ye-oil conservator kufanele ivalwe)

(2) Vacuum, inani le-vacuum kufanele lifinyelele ku-133pa, bese ligcinwa isikhathi esithile (110 kV amahora ama-4, 220 kV amahora ayi-8). Vacuum ayivunyelwe ngokuphelele esimweni sezulu esinemvula nesinomswakama njengomswakama ongaphezu kuka-75%.

(3) Ngemva kokuba izinga le-vacuum seligcinwe isikhathi esithile, qala ukujova uwoyela. Ukujova uwoyela kufanele kube kusukela ku-valve yokungena uwoyela phansi kwethangi elikhulu likawoyela we-transformer, bese umisa ukujova uwoyela lapho ibanga lokujova lingu-200mm-300mm ukusuka phezulu kwethangi.

Izinyathelo Zokuqapha Zokwengeza Uwoyela ku-Transformer

(1) Uma i-transformer igcwele uwoyela ngemva kokugcwaliswa kwamafutha e-vacuum, idinga ukujovwa ngepayipi lokugcwalisa uwoyela le-conservator yamafutha, futhi akuvunyelwe ngokuphelele ukujova kusuka ku-valve yethangi likawoyela elingezansi.

(2) Ngezimbobo zomoya ezifana nesihlalo sokuphakamisa i-casing kanye nepayipi eliphezulu le-radiator, i-exhaust kufanele ikhishwe izikhathi eziningana kuze kube yilapho iphela.

(3) Igesi engaphakathi kwegumbi likawoyela le-conservator kawoyela kufanele ikhishwe ukuze kuvinjelwe izinga likawoyela elingamanga. Kuma-conservator kawoyela anezakhiwo ezahlukene, izindlela zokukhipha zihlukile, kodwa ekugcineni isimiso sokuhlola esiyinhloko: uwoyela ophuma emgodini wokukhipha kusho ukuthi igesi ikhishwa kahle.

Izinyathelo Zokuphepha

(1) Abasebenzi abasebenza ezindaweni eziphakeme kumele baphumelele ukuhlolwa ngokomzimba futhi bathole isitifiketi sokusebenza esikhethekile ngaphambi kokuba baqale ukusebenza ezindaweni eziphakeme.

(2) Abasebenzi abasebenza ezindaweni eziphakeme kufanele basebenzise amabhande esihlalo ngendlela efanele, futhi amabhande esihlalo avinjelwe ngokuphelele ukuba alengiswe phansi naphezulu.

(3) Abasebenzi abakhethekile kufanele babelwe ukuqapha umsebenzi ezindaweni eziphakeme.

(4) Imishini yokulwa nomlilo efanele kufanele ifakwe lapho kwenziwa imisebenzi kawoyela endaweni.
