Emhlabeni wokusabalalisa ugesi,I-LVI-switchgearidlala indima ebalulekile ekulawuleni, ekulawuleni, nasekuvikeleni amasistimu amandla kagesi aphansi.
Kulo mhlahlandlela, sizohlola ukuthi iyini i-LV switchgear, ukuthi isebenza kanjani, izingxenye zayo, izinhlelo zokusebenza, amazinga, nokuthi kungani ibalulekile ezinhlelweni zikagesi zesimanje.
Iyini i-LV Switchgear?
I-LV switchgear, nomaI-Painel de distribuição de baixa tensão, isho okokusebenza kukagesi okuklanyelwe ukulawula, ukuvikela, nokuhlukanisa amasekhethi kagesi asebenza ngama-voltage aphansi — ngokuvamile achazwa ngokuthi ≤1000V AC noma ≤1500V DC.
Imisebenzi eyinhloko ye-LV switchgear ihlanganisa:
- Ukuvikela amasekhethi ekulayishweni ngokweqile kanye namasekethe amafushane
- Ivumela ukunqanyulwa okuphephile ukuze kulungiswe
- Ukulawula ukusatshalaliswa kwamandla kagesi
Izingxenye Ezibalulekile ze-LV Switchgear
Uhlelo lwe-LV switchgear ngokuvamile luhlanganisa izinto ezilandelayo:
1.Ama-Circuit Breakers
Vikela isekethe ngokunqamula amandla ngokuzenzakalelayo uma kwenzeka kuba namaphutha njengokugcwala ngokweqile noma amasekhethi amafushane.
- Ama-Miniature Circuit Breakers (MCB)
- I-Molded Case Circuit Breakers (MCCB)
- Ama-Air Circuit Breakers (ACB)
2.Amaswishi nama-Isolators
Vumela ukulawula okwenziwa ngesandla noma ukude kwamasekhethi, okuvumela ukuhlukaniswa okuphephile ukuze kulungiswe noma kusebenze.
3.Oxhumana nabo
Isetshenziselwa ukulawula amamotho kagesi noma amasistimu okukhanyisa ngokushintsha okuqhutshwa ukude.
4.Amadivayisi okudlulisela kanye nokuvikela
Thola amaphutha bese uthumela amasiginali ukuphazamisa ukunikezwa kwamandla noma ukucupha ama-alamu.
5.Amabhasi
Amakhondatha asabalalisa amandla ngaphakathi kwephaneli ye-switchgear.
6.Izivalo
Nikeza ukuvikela okungokwenyama kwezingxenye futhi uqinisekise ukuphepha ngendawo evalekile enesilinganiso se-IP.
Izinhlobo zokucushwa kwe-LV Switchgear
I-LV switchgear itholakala ngezindlela ezahlukahlukene ngokuya ngesicelo:
- Amabhodi Okusabalalisa Ayinhloko (MDBs)
Amaphaneli aphakathi nendawo asabalalisa ugesi kumasekhethi amancane ahlukahlukene. - Izikhungo Zokulawula Izimoto (MCCs)
Amaphaneli akhethekile okuphatha amamotho kagesi anomthwalo omningi, isiyingi esifushane, nokuvikelwa kokulawula. - Amabhodi Okusabalalisa Okungaphansi (ama-SDB)
Amaphaneli esibili asetshenziswa ezinhlelweni zezohwebo nezindawo zokuhlala zokulawulwa kwendawo. - Izinsika Zomphakeli
Amayunithi angaphandle asetshenziselwa izibani zasemgwaqweni, iziteshi ezincane, noma ukusabalalisa amandla okude.
Izicelo ze-LV Switchgear
I-LV switchgear isetshenziswa noma yikuphi lapho amandla kagesi esetshenziswa futhi adinga ukulawulwa.
- Izitshalo zezimboni (izimboni, imigqa yokukhiqiza)
- Izakhiwo zezentengiselwano (izitolo ezinkulu, amahhovisi, amahhotela)
- Izakhiwo zokuhlala (izindlu zangasese, ama-villas)
- Izibhedlela, izikhumulo zezindiza, nezinhlelo zokuthutha
- Izinhlelo zamandla avuselelekayo (amaphaneli e-solar PV, amabhange ebhethri)
- Izikhungo zedatha namanethiwekhi ocingo
Amazinga kanye Nezitifiketi
Lapho uthola noma ukhiqiza i-LV switchgear, ukuthobela izindinganiso zamazwe ngamazwe kubalulekile ukuze kuqinisekiswe ukuphepha nokuhambisana.
