Ama-Fuses angumugqa obucayi wokuzivikela ezinhlelweni zikagesi, evikela amasekethe kanye nemishini evela ezimeni ezingapheli. I-Low Voltage (LV)na-I-High Voltage (HV)Ama-fuse abalulekile kunjiniyela, abafaki, kanye nabahleli bamandla.
Umqondo Oyisisekelo: Yini ama-LV ne-HV Fuses?
Fus aphansi ama-voltage fusezivame ukusetshenziswa kumasekethe ngama-voltages angezansi 1,000v ac.
Ama-fuse aphezulu we-voltage, ngakolunye uhlangothi, zenzelwe ukusebenza emibuthanweni ngenhla kwe-1,000V, imvamisa kuze kube ngu-72.5kV noma ngaphezulu.
Izindawo zohlelo lokusebenza futhi usebenzise amacala
I-LV fuse
- Amaphaneli wokusabalalisa wokuhlala
- Izintaba zemoto nabaxhumana nabo
- Ama-switchboards wezentengiselwano
- Ukukhanyisa okuphansi kwamandla nezinhlelo ze-HVAC
Ama-HV fuses
- Ukusatshalaliswa kwezinto kanye namayunithi amakhulu aphambili (RMUS)
- Amandla weTransformers (11KV, 33kv, njll)
- Amabhange eCapacitor aphakathi nendawo- ne-High-Voltage
- Amandla wamandla avuselelekayo kanye ne-switchgear
Ukwehluka Kwezobuchwepheshe
| Ubuso | I-LV fuse | I-HV fuse |
|---|---|---|
| Isilinganiso seVoltage | Kufika ku-1,000V AC / DC | Ngaphezulu kwe-1,000V (kufika ku-72.5kV noma ngaphezulu) |
| Impahla yomzimba | Ipulasitiki, ingilazi, noma i-ceramic | I-Porcelain, i-epoxy resin, noma i-composite |
| Indlela yokuphazamiseka ye-ARC | Isixhumanisi sensimbi sincibilika | Ukuxoshwa okugcwele isihlabathi noma igesi |
| Usayizi nokukhuphuka | Icwecwe, isitayela se-cartridge | I-ende-in noma uhlobo lwe-plug-in |
| Izidingo zokulungiswa | Ukubuyiselwa kwamathuluzi-ngaphansi | I-PPE ekhethekile nokuphathwa kwe-arc-flash |
Imakethe Insights nokuma okujwayelekile
Ngokuvumelana neIeee,I-IEC, futhiUyema, ukuthambekela komhlaba wonke kukhombisa ukwanda okuqinile kwesidingo se-HV Fuses eqhutshwa yisidalwa sanamuhla kanye nokuhlanganiswa kwegridi evuselelekayo.
- I-LV fusebalawulwa yiIEC 60269na-Ul 248
- Fuses ye-HVfuzaIEC 60282-1,Iee C37.40, futhiI-ANSI C37.46
Imikhiqizo eholayo efanaAbisa,Schneider Electric,Sisaba, futhiIdlinaQhubeka nokuqhubekisela phambili zombili izigaba ngokwethula ama-fuses ngezinto ezithuthukisiwe ze-arc-junching, izinketho zokufaka ze-modular, nokuxilongwa kwe-smart-fuse.
Design Ukucatshangelwa kanye nokukhethwa komkhiqizo
Lapho ukhetha uhlobo lwe-fuse efanele, kufanele kuhlolwe izici eziningana:
- I-System Voltage futhi yamanje
- Isikhundla esifushane sokuphazamisa
- Izimo zezemvelo (E.G., izinga lokushisa, umswakama)
- Izingqinamba zosayizi nokuhlelwa kokufakwa
- Izitifiketi Zokuhambisana Nezindinganiso Nezitifiketi Zokuhlola
Isibonelo, ama-FV akhawulela ama-HV ama-HV alungele i-compact strainkegue lapho amandla amaphutha kufanele alawulwe, kanti ama-LV wesikhathi sokubambezeleka we-LV angasetshenziselwa ukuhamba ngezinto ezilandelwa yi-inrush.
Ukwahluka Okusemqoka Kufingqiwe
- Isilinganiso seVoltage:Lv = kufika ku-1,000V;
- Ukufaka:Lv = i-Quick-Mount;
- Ukuphathwa kwe-ARC:Lv = izinto ezincibilikayo;
- Izindleko nobunzima:Ama-FV fuse adinga ukuphathwa okuqinile nokuklanywa kokufakelwa
Imibuzo ebuzwa njalo (i-FAQ)
A: Cha. I-HV Fuse yenzelwe izimo ezahlukahlukene ze-dielectric ne-thermal futhi ayifanele noma iphephile kwizicelo ze-LV.
A: Akunjalo.
A: Yebo.
Umehluko phakathi kwe-FV ne-HV fuse ahlanganise ekilasini le-voltage kuphela kodwa emklamo wesakhiwo, izidingo zokuphepha, kanye nokufaneleka kohlelo lokusebenza.
IshaniselaInikeza uhla oluphelele lwemikhiqizo eqinisekisiwe ye-LV ne-HV fuse yamaphrojekthi we-Global Electrical Ingqalasizinda, ngokusebenza okufakazelwe kuwo wonke amazwe angama-30 +.
