Ama-Fuses ayingxenye eyisisekelo ezinhlelweni zokuvikela ugesi, eklanyelwe ukuphazamisa ukugeleza kwamanje uma kwenzeka amaphutha. I-low-voltage (LV)na-I-high-voltage (HV)Izinhlobo, ngakunye okuhambisana nezindawo ezithile zikagesi. Isiqondisi se-FuseAmakilasi aqakathekile onjiniyela, abaphathi bendawo, kanye nochwepheshe bokuthengwa kwempahla abanikezwe umsebenzi wohlelo kanye nokuhambisana.
Umqondo Oyisisekelo: I-LV vs HV fuses
Fus-voltage fuseszilinganiswe ngemibuthano ngokujwayelekile ngaphansi kwama-1,000 volts, kantiAma-fuse aphezulu we-voltagezenzelwe izinhlelo ezisebenza ngenhla kwe-1 000 volts - imvamisa zifinyelela ku-72.5 kV noma ngaphezulu.
Izindawo zohlelo lokusebenza
Fus-voltage fuses
Isetshenziswa ezinhlelweni zamazinga okusabalalisa kanye nezimboni:
- Izakhiwo zokuhlala nezentengiso
- Amaphaneli okulawula kanye nezitha zemoto
- I-switchgear ephansi ye-voltage (ngezansi 1KV)
Ama-fuse aphezulu we-voltage
Kusetshenziswe ezinhlelweni zebanga lengqalasizinda:
- Ukuhanjiswa kwamandla kanye namagridi okusatshalaliswa
- Ukufakwa esikhundleni kanye namayunithi amakhulu aphambili (RMUS)
- Abaguquli, amabhange eCapacitor, kanye ne-Utility switchgear
Umehluko Osemqoka Esakhiweni Nomsebenzi
| Ubuso | I-LV fuse | I-HV fuse |
|---|---|---|
| Isilinganiso seVoltage | Kufika ku-1 000 v | Ngaphezulu kwe-1 000 v (kufika ku-72.5 kV noma ngaphezulu) |
| Ukwakha | Uhlobo lwe-cartridge, compact | Isikhathi eside, esasinda kakhulu, esivame ukugcwaliswa isihlabathi |
| Ukuphazamisa Ukuphazamisa | Okuphakathi nendawo kuya phezulu | Phezulu kakhulu (kaningi> 50 ka) |
| I-Arc Quncing Indlela | Insimbi incibilika futhi ivulekile yokunqamula umoya | Ukugcwala okugcwele isihlabathi noma igesi-ukuxoshwa kwe-arc |
| Ukubuyiselwa | Ithuluzi-ngaphansi emiklamo eminingi | Idinga amathuluzi afakiwe noma abasebenzi abaqeqeshiwe |
Izitayela nezindinganiso zezimboni
Ngobunzima obukhulayo wegridi nokwanda kokuthembela kumandla avuselelekayo, ama-fuse design avele ukuze ahlangabezane nokuphepha okujwayelekile kanye nezidingo zokusebenzisana. Iee C37,IEC 60269 (LV)na-IEC 60282-1 (HV)Amazinga amabhentshi aphambili ezokukhiqiza nokuhlola.
Izinkampani ezifanaSchneider Electric,Abisa, futhiIdlinaZitshale imali kakhulu e-R & D yama-fuse athuthukile ahlinzeka ngezikhathi zokuphendula ngokushesha, ukulungiswa okuncishisiwe, nokulandela umkhondo wokuphila okuthuthukile.
Amapharamitha obuchwepheshe okufanele acatshangelwe
Lapho ukhetha phakathi kwe-LV ne-HV Fuses, onjiniyela kumele bahlaziye:
- I-voltage ekalwe futhi yamanje
- Ukuqhekeka komthamo
- Isikhathi Sokuphendula (ukusheshisa okusheshayo vs. Ukubambezeleka Kwesikhathi)
- Izimo zezemvelo(umswakama, uthuli, izinga lokushisa)
- Ukuxhumanisa nokudluliselwa kanye nokuqhekeka
Sebenzisa izibonelo zamacala
- I-LV Fuse:I-fuse yesikhathi esingu-400V yokuvikela isikhathi esivikela isikhungo sokulawulwa kwezimoto efektri.
- I-HV fuse:Kufakwe i-fuse engu-33kV ekhawulelwe efakwe kuyunithi main main endaweni.
Izeluleko zokukhetha
- Ungalokothi ungene esikhundleni se-LV Fuses ngezinhlelo zokusebenza ze-HV-Kusekuvumi ukuthi izilinganiso zibonakala zifana.
- Cabanga ngezivumelwano zokuphepha: Ama-FV Fuses avame ukudinga i-PPE ekalwe yi-arc nezinqubo zokuhlukaniswa.
- Bheka izitifiketi: Qinisekisa ukuthi wonke ama-fuse ahlolwe nge-IEC noma amazinga e-ANSI.
- Fakazela uhlelo lwesikhathi esizayo: Khetha ama-fuse angahlalisa ukukhula komthwalo okulindelekile noma ukuthuthukiswa kwegridi.
I-FAQ: I-LV vs HV Fuses
A: Cha. I-HV Fuse yenzelwe izici ezihluke ngokuphelele zokuphazamisa kanye namafomethi wokufaka.
A: Kokubili kuphephile lapho kusetshenziswa kahle.
A: Cha. Njengemfucumfucu ye-LV, ama-fuse we-HV asetshenziswa ngakunye futhi kufanele athathelwe indawo ngemuva kokuhlinzwa.
Ngenkathi i-LV ne-HV fuse isebenza umsebenzi ofanayo wokuvikela, ukwakhiwa kwawo, ukufakwa, nokusebenza kuyahlukahluka kakhulu.
IshaniselaInikeza zombili izixazululo ze-fuse eziphansi neziphakeme, ezihlolwe kumazinga omhlaba futhi asekelwa ubuchwepheshe bobuchwepheshe ekuvikelweni kohlelo lwamandla.
