Emhlabeni wokusatshalaliswa kukagesi,IthumbeIsingeluIdlala indima ebalulekile ekuphatheni, ukulawula, nokuvikela amasistimu wamandla aphansi aphansi.
Kulesi umhlahlandlela, sizohlola ukuthi yiliphi i-LV switchgear, lisebenza kanjani, izingxenye zalo, izicelo, amazinga, nokuthi kungani kubalulekile ezinhlelweni zesimanje zikagesi.
Yini i-LV switchgear?
I-LV switchgear, nomaI-Voltage Voltage Volvage, kubhekiswa kwimishini kagesi eyenzelwe ukulawula, ukuvikela, nokuhlukanisa amasetheli kagesi asebenza ngama-voltages aphansi - kuchazwa ngokujwayelekile njenge-≤1000V AC noma i-≤1500V DC.
Imisebenzi eyinhloko ye-LV switchgear ifaka:
- Ukuvikela amasekethe ekugcwalisweni ngokweqile kanye nemibuthano emifushane
- Inika amandla ukunqanyulwa okuphephile kokulungiswa
- Ukulawula ukusatshalaliswa kwamandla kagesi
Izingxenye ezisemqoka ze-LV switchgear
Uhlelo lwe-LV switchgear ngokuvamile luhlanganisa izinto ezilandelayo:
1.Abaphula umjikelezo
Vikela umjikelezo ngokukhipha amandla ngokuzenzakalelayo uma kwenzeka amaphutha njengokulayishwa ngokweqile noma amasekethe amafushane.
- Ama-Breaker Circuiture Circuit (MCB)
- AbakwaBelitali Ababunjiwe Breakers (MCCB)
- Abaphula umjikelezo womoya (ACB)
2.Ukushintshwa kanye nama-isolators
Vumela Ukulawulwa Kwemanuwali noma Kukude Kwemibuthano, kunika amandla ukuhlukaniswa okuphephile kokugcinwa noma ukusebenza.
3.Abaxhumene nabo
Kusetshenziselwa ukulawula ukuhamba kukagesi noma amasistimu wokukhanyisa ngokushintsha okukude.
4.Kudlulisela namadivayisi okuvikela
Thola amaphutha bese uthumela amasiginali ukuphazamisa ukuhanjiswa kwamandla noma ama-alamu.
5.Amabhasi
Abaqhubi abasabalalisa amandla ngaphakathi kwephaneli ye-switchchgear.
6.Thwalisa
Nikeza ukuvikelwa ngokomzimba zezakhi futhi uqinisekise ukuphepha ngezindawo ezikalwe ukulinganiselwa kwe-IP.
Izinhlobo zokucushwa kwe-LV switchgear
I-LV switchgear itholakala ngezindlela ezahlukahlukene ngokuya ngesicelo:
- Amabhodi Okusatshalaliswa Main (ama-MDBS)
Amaphaneli aphakathi nendawo ahambisa ugesi emibuthanweni ehlukahlukene. - Izikhungo Zokulawula Izimoto (MCCs)
Amaphaneli akhethekile wokuphatha ama-motors kagesi ngokulayisha ngokweqile, umjikelezo omfushane, nokuvikela. - Amabhodi Okusatshalaliswa Okungezansi (ama-SDB)
Amaphaneli wesibili asetshenziswa ezinhlelweni zezentengiso nezokuhlala zolawulo lwasendaweni. - Izinsika eziphakelayo
Amayunithi angaphandle asetshenziselwa ukukhanyisa emgwaqweni, izinto, noma ukusatshalaliswa kwamandla okude.
Izicelo ze-LV switchgear
I-LV switchgear isetshenziswa lapho amandla kagesi edliwa futhi adinga ukulawulwa.
- Izitshalo zezimboni (amafektri, imigqa yokukhiqiza)
- Izakhiwo Zentengiso (Izitolo ezinkulu, Amahhovisi, Amahhotela)
- Izakhiwo zokuhlala (amabhlokhi efulethini, ama-villas)
- Izibhedlela, izikhungo zezindiza, kanye nezinhlelo zokuhamba
- Izinhlelo zamandla avuselelekayo (amaphaneli e-solar PV, amabhange ebhethri)
- Izikhungo zedatha namanethiwekhi we-telecom
Amazinga nezitifiketi
Lapho sisongela noma sokwakha i-LV switchgear, ukuhambisana namazinga aphesheya kubalulekile ukuze kuqinisekiswe ukuphepha nokuhambisana.
- IEC 61439-1- Izidingo ezijwayelekile ze-LV Switchgear Assemblies
- IEC 60947- Yezakhi ze-switchgear ngayinye ezinjengabaphukile nabaxhumana nabo
- UL 891 / UL 508A- U.S. Izindinganiso zamaphaneli namaphaneli okulawula
- En 61439- I-Europe Elijwayelekile eliqondaniswe ne-IEC
Izinzuzo zokusebenzisa i-LV esezingeni eliphakeme
- Ukuphepha OkuthuthukisiweKwezisebenzi nemishini
- Ukuvikelwa Okuthembekilengokumelene namaphutha kagesi
- Ukusatshalaliswa kwamandla okusebenza kahleezindaweni eziyinkimbinkimbi
- Idizayini esezingeni elifaneleOkwengeziwe esikhathini esizayo
- Ukuqapha okuhlakaniphilengokusebenzisa i-scada noma ukuhlanganiswa kwe-iot
