Amafutha wesifunda full. Izinhlobo uwoyela wesifunda amadlambi

Ukuze wenze ngokuzenzakalelayo ukusebenza kwe-imishini ukuthi ifakwa amandla kagesi, usebenzisa ekhethekile uwoyela wesifunda oluseduze.

Oil inkinobho - idivayisi okuyinto uqhuba ukuqalisa kokusebenza noma ukungaqaliswa lezifunda lomuntu phansi isimiso sikagesi, kwimodi yayo yokusebenza ejwayelekile noma uma kunesimo esiphuthumayo, ngesandla noma automatic uhlelo umyalo. idivayisi okunjalo isetshenziswa inhlangano kwabaningi ukunikezela ngamaketanga.

imishini ngezigaba

Ukuqinisekisa operation esitebeleni of imishini kagesi lingasetshenziswa elandelayo izinhlobo uwoyela wesifunda:

• Uhlelo nge umthamo eliphezulu namafutha kuwo - mathangi.
• Ukusebenzisa izakhi Kwe-dielectric Heating kanti imali encane yamafutha - ongaphakeme-uwoyela.

Isikimu uwoyela inkinobho has idivayisi esikhethekile zokucisha lwesikhathi imiswe phakathi uchungechunge scission. Isimiso ezisebenza amadivaysi arc imishini enjalo luhlukaniswe amaqembu ezilandelayo:

• Ukusebenzisa ophoqelelwe emoyeni kuqhuma ukusebenza imvelo. idivayisi okunjalo indlela ekhethekile wokubacindezela ngoba ingcindezi futhi usinika fuel esizeni ukudabuka of a chain.
• eqeda Magnetic emafutheni uqhutshwa usebenzisa electromagnets ekhethekile izakhi okuyinto ukukhiqiza inkambu ushukumisela arc ku iziteshi ukwa ewumngcingo adalwe circuit.
• Amafutha inkinobho avtodutem. Isikimu uwoyela inkinobho yalolu hlobo sihlinzekela esitokisini esikhethekile ohlelweni, okuyinto lucwaningo ukukhululwa amandla amaningi avela arc sona ukuhamba uwoyela noma igesi ethangini.

Uhlobo ithangi uhlelo

Dead Tank Circuit Breakers athandwa kakhulu ngenxa inkimbinkimbi umklamo. Amafutha siqukethe inkinobho input bese arc contact uhlelo, okuyinto ibekwe ethangini ngamafutha. Uma usebenzisa imishini ohlelweni bonke oxhumana nabo ezintathu nge voltage ka 3-20 kW (izigaba) zingahlelwa ngethangi elilodwa, nge Inkomba 35 kV voltage isigaba okwandisa kumele itholakale ethangini ehlukile. Ezimweni ezimbili kungashiwo Nokho esetshenziselwa othomathikhi noma elawulwa kude uhlelo, ngoba samuntu sokuqala Ungasebenzisa imodi ibhukwana, kanti eyesibili kudinga ukuqalisa phansi we umshini.

Ngaleso hlobo odnobakovogo lapho zonke izigaba ezintathu yilezi kule esitsheni efanayo ngamafutha esetshenzisiwe ukusebenza uketshezi Umqhubi contact ngci komunye nomunye futhi kusukela umzimba ethangini ukuze eqinile. Amafutha, ngaphezu, ukhonza sinqande arc kwakhiwa futhi kwemihlambi ugesi izigaba komunye nomunye ngesikhathi ukwa inethiwekhi.

Umgomo we operation sekuqalile odnobakovyh

Lapho kwabangela, uhlelo kwenzeka Ungowokuqala okuxhunyanwa naye igebe arc ekamelweni. Ngezinye ikhefu ukuxhumana high voltage inethiwekhi i arc, okuyinto ubola amafutha ngenxa ukuchayeka lokushisa eliphezulu. Ngaphansi kwethonya arc phezu uwoyela negesi bubble kumiswa kwenzeka, okuyinto kuyoba arc uqobo. I wadala bubble 70% e-hydrogen, futhi lokhu igesi Siyonikwa ngaphansi kwengcindezi kule wombuso. Ukuchayeka hydrogen ne eyayenziwe ingcindezi elakhiwe kuzoholela arc deionalizatsii imiswe phakathi contact ikhefu. Encwadini efanayo ngendlela inkinobho uqhuba uwoyela wesifunda.

Isimiso ezisebenza we inkinobho trehbakovogo

Trehbakovy inkinobho has a isimiso ukuhluka wokusebenza, ngenxa yokusetshenziswa kwawo ephezulu voltage inethiwekhi. Amafutha inkinobho okuyinto esetshenziswa amanethiwekhi ne voltages ngenhla 35 kV, e-arc zokucisha ekamelweni has a indlela ekhethekile ngokudala kuqhuma. Ezisetshenzisiwe interrupter uhlelo kungaba kuqukathe izindlela eziningana wokusebenza. Bavumela ukukhuphula ijubane blowout ngesikhathi contact zizalela.

Ukuze uvikele le nqubo, izakhi ugesi okuxhunyanwa ezibekwe kwesigubhu okhethekile uwoyela, usebenzisa ethangini ehlukile isigaba ngasinye. Futhi, oshayelayo ahlukahlukene uwoyela wesifunda amadlambi, ukuvumela ukuhambisa uketshezi esebenza isiqondiso ekhethiwe. Uhlelo has a isici esikhethekile ukulawula ubukhulu arc, okuyinto imelelwa shunt. Ngemva kokwehluleka kwe-arc ezakhiwe wamanje anqunywe ngokuphelele.

Izinzuzo ohlelweni

uhlelo arc zokucisha yalolu hlobo enezinto eziningi izici, ngenxa ngalo isetshenziswa abaningi supply ngamaketanga. Izinzuzo ohlelweni zihlanganisa:

• Ukusebenza kahle eliphezulu ngesiphazamiso wesifunda evumela ukusetshenziswa imishini enjalo kumanethiwekhi we voltage okusezingeni eliphezulu.
• Ukuba lula kwezincazelo design kwenza kube okunokwethenjelwa futhi maintainable. Ukulungisa of ukushintshwa uwoyela kufanele sigcwaliswe kuphela ochwepheshe, njengoba imishini enjalo unesibopho ekukhishweni i team ebalulekile othomathikhi indawo elawula uhlelo noma u-opheretha. Iphinde inquma izinga izindleko iphansana yalolu hlobo imishini.

nemibi uhlelo

Naphezu ukuthandwa okwandayo zalesi simiso zokucisha le arc kagesi, ezakhiwe ukudabuka othintana okuyinto, it has ezithile:

• Ukusebenzisa yenqwaba uwoyela ukuqinisekisa ukusebenza onokwethenjelwa kunayo yonke.
• Elikhulu usayizi ekuqhumeni mfutho elihlobene ne isidingo ukusebenzisa amafutha in inqwaba.
• Fire ingozi. Ngenxa yokuthi ngesikhathi kumiswa lokushisa arc ukwanda uwoyela. Uma inani uketshezi ukusebenza ingaphansi elinconyiwe, kungenzeka ukuba nithele nomlilo.

Low-uwoyela ngohlobo lomshini

Shintsha uwoyela VMP, ongaphakeme-amafutha, noma ngamanye amazwi, ngaphandle uketshezi sisebenzela ukuqinisekisa isici kwemihlambi uhlelo komunye nomunye, ke inezici ekhethekile esakhiwe ngezinto Kwe-dielectric Heating. Kulokhu amafutha isetshenziselwa kuphela kumiswa igesi. Ngalinye timphawu uhlelo, lapho wesifunda yehlukile kudivayisi arcing ekamelweni. Lisebenzisa drive uhlelo olukhethekile, esihlinzeka cross-ekushayweni.

Ngenxa lemali encane yamafutha ngesikhathi isimo off oxhumana zitholakala phezulu zidlule amafutha asetshenziswa ekamelweni, okwandisa ukuthembeka discontinuity kagesi. Ngenxa ukungcoliswa imvelo kungase ekugcineni alahlekelwe ilungelo ewumgogodla Kwe-dielectric Heating izakhiwo. Futhi, uma udala isimiso esinjalo, abaklami baye kunakwe yokuthi ngokuhamba kwesikhathi, imikhiqizo noqhekeko akhiwa. Kubo, wadala ngokukhethekile uwoyela separators.

Emihle nemibi uhlelo

Amafutha wesifunda amadlambi yalolu hlobo avame ukusetshenziswa ukunikeza okunokwethenjelwa kwenethiwekhi ikhefu ugesi amasekethe ubude amancane umthamo. zako zihlanganisa lezi ezilandelayo:

• Ukusebenzisa imali encane yamafutha.
• Usayizi elincane nesisindo ukwakhiwa, okwandisa nobukhulu bayo.

Lezi izimfanelo ezinhle ivunyelwe ukuthi isebenzise uhlelo inethiwekhi ye igebe ukuvuselelwa kwamandla kagesi amabhizinisi, amahhovisi kanye nezinye izakhiwo zezimboni, lapho kukhona inethiwekhi ephezulu voltage.

I yokuntula zihlanganisa lezi ezilandelayo:

• Ukuqinisekisa ukuthembeka isidingo sihlale njalo siqaphele izinga uwoyela phezulu uma kunesidingo.
• Izindleko eziphezulu zokuthola izidingo imishini elihlobene ne ukusetshenziswa kwezinto eziphinde zisebenziseke ezibizayo Kwe-dielectric Heating ekukhiqizeni yayo.

Uhlobo uwoyela wesifunda kuyakhethwa ngokuvumelana nezici ugesi wesifunda lapho isetshenziswa basuke.
