Emkhakheni wobunjiniyela kagesi nokusatshalaliswa kwamandla, umehluko phakathiI-MV (VOID VOLTAGE)na-Lv (voltage ephansi)kubalulekile.
Kepha yini ngempela i-MV ne-LV emelela?
Le ndatshana ihlinzeka ngokuqhekeka okuningiliziwe kwe-MV vs LV, Ukusiza Onjiniyela, Abaphathi Bendawo, kanye nabahleli bengqalasizinda benza izinqumo ezinolwazi.
Izincazelo Eziyisisekelo: Yini i-MV ne-LV?
I-Medium Voltage (MV):
Imvamisa ibhekisa kuhlu lwe-voltage phakathiI-1KV ne-36KV(Amanye amazinga anwebeka lokhu kufika ku-72.5kv).
I-Low Voltage (LV):
Kuhlanganisa ama-voltages angezansiI-1000v ACnomaI-1500V DC, esetshenziselwa kakhuluindawo yokuhlala,-entengiso, futhiizimboni ezikhanyayoukusetshenziswa.
Izicelo: lapho kusetshenziswa khona i-MV ne-LV
| Ileveli ye-Voltage | Izicelo Eziyinhloko |
|---|---|
| I-MV (1KV-36KV) | - Izitshalo zokukhiqiza zezimboni - Amandla avuselelekayo axhumeke ngegridi - Ukusetshenziswa kokusetshenziswa - Izakhiwo ezinkulu zezentengiso |
| I-LV (<1000V) | - Izakhiwo zokuhlala - Amahhovisi nokuthengisa - Izikole kanye Nezibhedlela - Izikhungo zedatha, Izikhungo ze-IT |
Izinhlelo ze-MV ziyinkimbinkimbi ngokwengeziwe, zidinga ukuphathwa okuqeqeshiwe, futhi zivame ukufakwa ezindaweni lapho umthamo wamandla aphezulu kanye nokudluliselwa okude kuyadingeka.
Izitayela Zemakethe Nokuziphendukela Kwezobuchwepheshe
Isidingo seGlobal sokusatshalaliswa kwamandla okuthembekile sekugxilile, ikakhulukazi ekwakheni ezomnotho nasezindaweni ezandiswa zasemadolobheni. I-International Energy Agency (IEA), ukucindezela kuyeamagridi ahlukaniswena-izinhlelo zokusebenza ze-Smart PowerIngabe ukushayela ngokushesha ukutshala imali kwingqalasizinda ye-MV ne-LV.
Abakhiqizi abaphambili bathandaAbisa,Schneider Electric, futhiNokiawethule izixazululo ezi-modular ezihlanganisa izinhlelo ze-MV ne-LV kungakapheli izilinganiso zokufakwa kwezimali-ukuthuthukisa ukuhanjiswa kwesivinini nokusebenza okusebenzayo.
Amaphaneli we-Smart LVngokuhlanganiswa kwe-iot futhiI-MV switchgear nge-Arc-Flash Protectionziba ngcono kumaphrojekthi wengqalasizinda abucayi.
Amapharamitha Ezobuchwepheshe: Itafula lokuqhathanisa le-MV vs LV LV
| Ubuso | I-VoLtage Ephakathi (MV) | I-Low Voltage (LV) |
|---|---|---|
| I-Voltage Range | I-1KV kuya ku-36kv (kufika ku-72.5kv kwamanye amazinga) | Kufika ku-1000V AC / 1500V DC |
| Imishini ejwayelekile | I-Switchgerear, ama-ring amayunithi main (Rmus), abaguqukayo | Amabhodi okusabalalisa, ama-MCCB, ama-MCB |
| Ukwahlukanisa | I-SF6, i-vacuum, efakwe umoya | Kakhulu kufakwe umoya |
| Izinja | Ukuhanjiswa kanye nokusatshalaliswa kwezimboni | Ukunikezwa kwamandla okuqondile kubasebenzisi bokugcina |
| Ukuhlalisa | Kudinga abasebenzi abaqeqeshiwe | Kuyinkimbinkimbi encane, evame ukuphathwa ngogesi |
| Ukufaka | Ngaphakathi / ngaphandle, izinyawo ezinkulu | Ngaphakathi, izinketho ezihlanganisiwe nezimodeli ziyatholakala |
Umehluko osemqoka ngokubheka nje
- Ukuphepha:I-LV iphephe ukuphatha, ngenkathi i-MV idinga ukuvikela kanye nezivumelwano zokuphepha ze-arc-flash.
- Inkimbinkimbi:Izinhlelo ze-MV zidinga izingxenye ezikhethekile nokufakwa kokufakwa.
- Izindleko:Imishini ye-MV nokufakwa ngokuvamile kubiza kakhulu ngenxa yokufakelwa kanye nezinhlelo zokulawula.
- Amandla Amandla:Izinhlelo ze-MV zingadlulisela amandla aphezulu ngaphezulu kwamabanga amade.
Ukuthenga nokuklama
Lapho uklama noma uthenga amasistimu wokusabalalisa kagesi:
- QokaIzinhlelo ze-MVLapho ubhekene nezidingo zamandla aphezulu (e.g., amapaki ezimboni, izinto ezisetshenziswayo).
- KhethaIzinhlelo ze-LVNgezindawo zasendaweni, ezifunwayo (e.g. Izindawo zokuhlala, amahhovisi amancane).
- Qinisekisa ukuthi zonke izingxenye zivumelana namazinga afanele afanaIEC 60038,IEC 62271, nomaIee C37.
Abathengisi abaholayoIshanisela,Abisa, futhiSchneider ElectricNikeza izixazululo ezihlanganisiwe ze-MV-LV ezihlanganisiwe ezihlangene, ezisebenza kahle, eziqinisekiswe ngokuphelele.
I-FAQ: MV vs lv
A:Yebo.
A:Kuya ngomthwalo wakho ophelele (KW / KVA), ibanga ukusuka ekuxhumeni kokuxhumeka kokuxhumana, kanye nemithetho yezokuphepha.
A:Izinhlelo ze-MV zidinga ukufukula, ukuvikelwa kwe-arc-flash, izinqubo zokuhlukanisa, kanye nokuhlolwa okujwayelekile ngabasebenzi abaqinisekisiwe.
Ukuqonda umehluko phakathi kwe-MV ne-LV kubalulekile kunoma ngubani obandakanyeka ekuhlelweni kokusatshalaliswa kwamandla noma ukuphathwa kwesikhungo.
Njengoba ingqalasizinda yasemadolobheni ivela futhi i-Energy Funesfum inyuswa, zombili i-MV ne-LV zizohlala zibalulekile ekwakhiweni kwesimanjeUmhlahlandlela kagesiamanethiwekhi.
