Ihlola izinhlobo eziphakeme ze-voltage fuse

Uma kukhulunywa ngokuvikelavoltage ephezuluIzinhlelo zikagesi,umfulaziphakathi kwezinto ezibaluleke kakhulu kodwa ezibalulekile. Akuwona wonke ama-fuse aphezulu we-voltage adalwe alingana.

Yini i-fuse ephezulu ye-voltage?

Emgodini wayo, aI-Pough Voltage FuseIngabe idivaysi yokuphepha yomhlatshelo eyenzelwe ukuphazamisa ama-currents ngokweqile kumasekethe asebenza kuma-voltages averev ngenhla kwe-1KV.

Ngokungafani namadivayisi ahlala kabusha anjenge-Breaker Breakers, ephezuluamandla kagesifusesayisebenzi kabushafuthi kumele ithathelwe indawo ngemuva kokusebenza.

Kusetshenziswa kuphi ama-voltage fuse aphezulu?

Uhla lwesicelo lwamandla aphezulu voltage as spans eziningi zezimboni kanye nama-voltage tiers.

Amacala okusebenzisa ukhiye:

• Ukuvikelwa kweTransformer(ukusatshalaliswa kanye nabaguquli bamandla)
• Ukuvikelwa Kwebhange laseCapacitor
• Imibuthano ye-Motor Starter
• Imihlangano ye-Switchgear (11KV, 33kV, nangaphezulu)
• Imigqa yokusabalalisa ngaphezulu
• Ukufakwa kuka-Raily Electrication kanye nokufakwa kokutholwa

Ama-fuse aphezulu we-voltage asetshenziswa kaningi eceleniukunqamula ukushintshwana-abaphula umjikelezoNgokukhetha okuthuthukisiwe nokuphepha, ikakhulukazi ekuhlolweni okuphakathi nendawo (njengoba kuphawuliwe nguI-Wikipedia - Ama-Flues aphezulu we-voltage).

Izinhlobo ezinkulu zama-fuse aphezulu we-voltage fuse

Manje, ake sihlole izinhlobo ezahlukahlukene zemfucumfucu ephezulu ye-voltage, ngalinye lihlelwe isu elithile lokuvikela.

Lawa ma-fus anciphisa ngokushesha iphutha lamanje ngokwethula ukumelana okuphezulu kwe-arc uma isixhumanisi se-fuse sincibilike.

Izinja: Abaguquli, amagiya okulawula, amaphaneli wezimboni.

2.Ukuxoshwa fuse

Waziwa nangokuthi "ama-fuse angewona akhawulelwe", lokhu kusetshenziswa igesi nengcindezi eyenziwe ngesikhathi sokuphonsa ukucisha iphutha.

Izinja: Imigqa yokusabalalisa ebekiwe ye-pole, izinto zangaphandle.

3.Ama-fus aphumayo

Iqanjwe ngomshini wabo owehla ngokoqobo lapho esebenza lapho esebenza, okwenza kucace ngokusobala ukuthi i-fuse iseshaye.

Izinja: Ama-Transformers wegridi asemakhaya, ama-11kv & 33kv feeders.

4.Dlulisa Uhlobo lwe-Cartridy

Kufakwe okufakwe ngokuphelele futhi kuvame ukuvalwa ngama-tubhu we-porcelain noma ama-fiberglass.

Izinja: I-Metal-Clad switchgear, amaphaneli okulawula.

5.I-Striker-Type Fuses

Lokhu kwenzelwe umgadli owenziwa ngomshini owenza umsebenzi wokusebenza kwe-fuse, evame ukuhambisa ukushintshana okuhambisana nakho.

Izinja: Imisipha yemoto, amabhange eCapacitor.

6.I-HV HRC (umthamo ophakeme wokuqina) fuses)

Lezi uhlobo lwe-fuse ekhawula yamanje eyenzelwe izilungiselelo ezisindayo zezimboni.

Izinja: Ama-Transformers wezimboni, okufakwayo ngemishini ebucayi.

Umongo wemakethe kanye nokuqonda kwemboni

Imakethe ye-voltage fuse ephezulu ibhekene nokukhula okuqinile, okuqhutshwa yi-Urban Grid Expansention, ukwamukelwa kwamandla okuvuselelekayo, kanye nesimanje sengqalasizinda. 2023 Umbiko kaGlobata, isifunda sase-Asia-Pacific sihola imakethe ngenxa yokwanda kukagesi ezindaweni zasemakhaya nasezinhlanganweni zasemadolobheni.

Abakhiqizi abaphambili abanjengoAbisa,Schneider Electric, futhiSisabaube nomthelela ekuvuseleleni imiklamo ye-fuse ukwamukela izakhiwo ze-compact switchgear futhii-smart gridizindawo.

Ngaphezu kwalokho, ukuhambisana namazinga afana:

• IEC 60282-1(Ngemfucumfucu ephezulu ye-voltage)
• IEEE STD C37.41
• I-ANSI C37.46

... uqinisekisa ukuphepha nokufana ezinhlekeleleni.

Ama-fes auses aphezulu vs Breaker Breakers: Uyini umehluko?

Ngenkathi bobabili besebenza njengamadivayisi avikelayo, ukusebenza kwabo kanye nokusebenzisa amacala ahlukile kakhulu:

• Umfulabasabela ngokushesha futhi bangconoUkuhlanza iphutha elilodwa.
• Abaphula umjikelezokungaba njalosetha kabusha, Ukuzenza kahle imisebenzi ephindaphindwayo.
• FusesAmadivayisi we-Passive, ngenkathi ama-breaker evame ukudingaAmandla asizayonoma alawule amasekethe.

Ezingeni elithile, onjiniyela bahlanganisa bobabili - besebenzisaFuses for Transformer Primary Ukuvikelwana-Breakers ngokushintsha kwemithwalo.

Amathiphu wokukhetha asebenzayo: Ukukhetha i-HV fuse efanelekile

Akuwona wonke ama-fuse ahambelana nawo wonke amasistimu. Imihlahlandlela EsebenzayoUkusiza onjiniyela kanye nabathengi benze okungcono kakhulu:

• I-Match System Voltage kanye nezilinganiso zamanje
  Njalo khetha i-fuse ekalwe kancane ngaphezulu kwebanga elijwayelekile lokusebenza.
• Cabanga ngephutha lamanje kanye nelephula umthetho
  Amandla aphezulu okuphula ama-fuse abalulekile kubaguquli abakhulu bezimboni.
• Ukucatshangelwa Kwezemvelo
  Ama-fuse angaphandle kufanele abe nokumelana nesimo sezulu, mhlawumbe enomklamo wokulwa nokuvunyelwa.
• Uhlobo lwesicelo
  Khetha ama-Flues akhipha amasu wezinhlelo ezifakwe izindwani nezinhlobo ze-cartridge zamakhabethe angaphakathi.
• Izindlela zokugaya ze-automation
  Uma ukuxhumanisa nge-breaker noma edluliselwe kudingeka, khetha izinhlobo zohlobo lomgadli noma amamodeli ahlomele izinkomba.
