Ukusebenza kwe-Dropout Fuse Cutout

Ulungiselelo lokhuseleko:

Xa ukhupha i-fuse yodidi lwethontsi, umqhubi kufuneka asebenzise intonga yokugquma enenqanaba lombane elifanelekileyo kwaye aphumelele uvavanyo, anxibe izihlangu zokugquma, iiglavu zokugquma, ikepusi yokugquma kunye nezibuko, okanye ame kwiqonga elomileyo leplanga, kwaye abe phantsi kweliso lokukhusela ukhuseleko lomntu.

Amanqaku:

Xa umqhubi eqala okanye ephelisa ukutsalwa okanye ukuvala i-fuse yokulahla, akuyi kuba nefuthe.Impembelelo iya kuyonakalisa i-fuse, njengokutsala kunye nokukrazula i-insulator, ukuphambukisa i-bill yedada, ukutsala kunye nokuphula umsesane wokusebenza, njl.

Amandla enkqubo ye-fuse acothayo (ukuqala) - ngokukhawuleza (xa uqhagamshelwano oluhambayo lusondele kwi-static contact)-cotha (xa uqhagamshelwano oluhambayo lusondele ekupheleni kokuvalwa) . Inkqubo yokutsala i-fuse icotha (ukuqala) - ngokukhawuleza (xa uqhagamshelwano oluhambayo lusondele kwi-static contact) -cotha (xa uqhagamshelwano oluhambayo lusondele ekupheleni kokutsalwa) Ukukhawuleza kukuthintela ukudibanisa okubangelwa ukujikeleza kombane okufutshane, ukutshisa umbane obangelwa yimpembelelo emfutshane yombane, ukutshisa i-circuit yombane kunye nokutshisa umbane. umonakalo kwifuse.

Thumela iodolo

Ulandelelwano lomsebenzi wokumisa ukunikezelwa kwamandla kwi-transformer yokusabalalisa ngolu hlobo lulandelayo: Kwiimeko eziqhelekileyo, ukutshintshwa kwe-voltage ephantsi kwicala lomthwalo kufuneka kutsalwe kuqala, kwaye emva koko i-fuse ye-high-voltage yokulahla kwicala lamandla kufuneka itsalwe.

Kwimeko yonikezelo lwamandla amaninzi, ngokulandelelana okungasentla kokuhamba kombane, kunokuthintela ukuhanjiswa kwe-transformer ngasemva, kwimeko yokusilela, ukhuseleko lunokwala ukuhamba, ukwandisa ixesha lokususwa kwempazamo, ukwenza ingozi ikhulise. Kwimeko yokusilela kwamandla, misa icala lomthwalo kuqala. Kulandelelwano lomsebenzi wokungaphumeleli kwamandla inyathelo ngenyathelo ukusuka kumbane ophantsi ukuya kwivoltheji ephezulu, iswitshi inokuphepha ukusika ukuqukuqela okukhulu kwangoku kunye nokunciphisa i-amplitude kunye ne-frequency yokusebenza phezu kombane.

Kumsebenzi, zama ukunqanda ukutsala kunye nokulahla iifuse ngomthwalo. Ukuba kufunyaniswe ukuba iifuse ezinomthwalo zichanekile ngexesha lokusebenza, nokuba iifuse zichanekile okanye i-arc yenzeke, ayivumelekanga ukuba iphinde ivule i-fuses.Ukuba i-fuse yokutsala engafanelekanga ngomthwalo kwenzeka, xa umnxibelelwano ohambayo ushiya nje umnxeba osisigxina, i-arc iya kwenzeka. Ngeli xesha, kufuneka ivalwe ngokukhawuleza ukuphelisa i-arc kwaye ugweme ukwandiswa kwengozi.Nangona kunjalo, ukuba zonke iifuse zikhutshwe zivulekile, akuvumelekanga ukuvala kwakhona iifuse ezikhutshwe ngephutha.Ukusabalalisa i-transformers kunye nomthamo we-200 kva okanye ngaphantsi, i-fuses kwicala eliphezulu lombane livumelekile ukuba lihlukane kwaye lidibanise umthwalo wangoku.

Ulandelelwano lokusebenza

Izigaba ezithathu zokulandelelana kokusebenza kwefuse yokuhla kwamandla ombane aphezulu.

Ukusebenza kokusilela kwamandla, kufuneka kuqala ukutsala isigaba esiphakathi, emva koko utsale omabini amacala esigaba.

Isizathu esona sizathu sokutsala isigaba esiphakathi kuqala kukuqwalasela ukuba i-current xa isigaba esiphakathi sinqunyulwa singaphantsi kwesigaba secala (inxalenye yomthwalo wesiphaluka ithwalwa zizigaba ezibini), ngoko ke i-arc incinci, kwaye akukho ngozi kumacala amabini esigaba. isiphaluka phakathi kwezigaba ezibangelwa yi-arc eyandisiweyo.Xa kukho umoya onamandla, kufuneka siqale sitsale isigaba esiphakathi, emva koko sitsale isigaba se-lee, kwaye ekugqibeleni sitsale isigaba somoya ngokulandelelana kokusilela kwamandla.

Xa uthumela umbane, amacala amabini esigaba sokuqala, emva kwesigaba esiphakathi.

Xa amandla ehanjiswa, isigaba sokuqala somoya, emva koko sibuyele kwisigaba se-phoenix, kwaye ekugqibeleni isigaba esiphakathi, ukwenzela ukukhusela isiphaluka esifutshane esibangelwa yi-arc yomoya.

Inqaku lofakelo

Izilumkiso zofakelo lwefuse yokuhla kwamandla ombane aphezulu

I-1, ukufakela kufuneka kube yintlupheko yokunyibilika (kunyibilika malunga noxinzelelo lwe-24.5N), kungenjalo kulula ukubangela ubushushu beenwele.

I-2, i-fuse efakwe kwingalo yomnqamlezo (isakhelo) kufuneka ibe yomelele kwaye inokwethenjelwa, ayinakho nayiphi na into yokugubha okanye yokugubha.

3. Umbhobho onyibilikayo kufuneka ube ne-Dip Angle ye-25 ° ± 2 °, ukwenzela ukuba umbhobho onyibilikayo uwele ngokukhawuleza ngobunzima bawo xa ukunyibilika kuhlanganiswe.

4. I-fuse kufuneka ifakwe kwi-arm ye-cross (isakhelo) kunye nomgama othe nkqo ongekho ngaphantsi kwe-4m ukusuka emhlabeni. Ukuba ifakelwe ngaphezu kwesiguquli sosasazo, kufuneka igcine umgama othe tye ongaphezulu kwe-0.5m ukusuka kumda wecontour ongaphandle we-transformer yosasazo, kwimeko yezinye iingozi ezibangelwa kukuwa kwemibhobho etyhidiweyo.

5. Ubude bombhobho onyibilikayo kufuneka bulungiswe ngokufanelekileyo. Kuyafuneka ukuba ulwimi lomlomo wedada lukwazi ukubopha ngaphezulu kwesibini kwisithathu sobude boqhagamshelwano emva kokuvala, ukuze kuthintelwe isenzo esingalunganga sokuwa ngokwalo ngexesha lokusebenza.

6. I-melt esetyenzisiweyo kufuneka ibe yimveliso eqhelekileyo yomenzi oqhelekileyo, kwaye unamandla athile omatshini. Ngokubanzi, inyibilika inokumelana namandla okuqina angaphezulu kwe-147N ubuncinci.

7. I-10kV yohlobo lwe-drop fuse ifakwe ngaphandle, kwaye umgama phakathi kwezigaba mkhulu kune-70cm.
