Kumahlelo wanamuhla wokusabalalisa kagesi,I-Switchchear ephansi ye-voltage (LV)Udlala indima ebaluleke kakhulu ekugcineni ukugeleza kwamandla okuphephile nokunokwethenjelwa.
YiniI-Voltage Voltage Volvage?
I-LV switchgearKubhekiswa ekushintsheni kukagesi nokuvikela amadivaysi aklanyelwe ukusebenza kuma-voltages aze afike ku-1,000v ac noma 1,500V DC.
Imisebenzi eyisisekelo ifaka:
- Ukushintsha nokulawula amasekethe kagesi
- Ukuphazamisa imisinga yokujikeleza okufushane
- Ukuhlukanisa amasekethe amabi
- Ukuvikela impilo yomuntu kanye namadivayisi axhunyiwe ezingozini zikagesi
Izakhi ezijwayelekile ze-LV Switchgear zifaka ama-Breaker Breakers, oxhumana nabo, ukushintshwa, ama-isolators, ukunqatshelwa kwe-fuse ukunqanyulwa, ukudluliselwa kokuvikela.
Isetshenziswa kuphi i-LV switchgear?
I-LV switchgear iyisisekelo ekufakweni okuhlukahlukene:
- Izakhiwo Zentengiso: Amahhotela, amahhovisi, izitolo zezitolo
- Izikhungo zezimboni: Amayunithi wokukhiqiza, ukucubungula izitshalo
- Izakhiwo zezikhungo: Izibhedlela, amanyuvesi, izikhungo zedatha
- Ingqalasizinda Yokwaziswa: Ukufakwa esikhundleni kwesibili, uhlangothi oluphansi lwe-voltage of transformers
- Izinhlelo ezingavuselelwa: Ama-inverterers kanye namayunithi wokusabalalisa we-solar pv
Izitayela Zemakethe Nentuthuko Yezobuchwepheshe
Iqhutshwa yi-Urban kanye nenguquko yedijithali, imakethe ye-LV switchgear ivela ngokushesha okukhulu. Umbiko we-Uneema Umbiko, isidingo se-compact, modular, kanye nezinhlelo ze-LV ezihlakaniphile zibalwa ngenxa:
- Ukukhula ezakhiweni ezihlakaniphile kanye nengqalasizinda
- Ukwanda ukuhlanganiswa kokuvuselelwa kanye nama-microgids
- Ukugcizelela ukuphepha, ukusebenza kahle kwamandla, kanye ne-automation
Abadlali abakhulu bathandaSchneider Electric,Nokia, futhiAbisabanikezela nge-LV switchgear ngokuqapha okususelwa ku-Iot, ukunciphisa i-arc flash, kanye nokuxilonga kwangempela.
Ukucaciswa Okusemqoka kanye Namapharamitha Ezobuchwepheshe
| Ukucacisa | Uhla olujwayelekile |
|---|---|
| Amandla kagesi | Kufika ku-1,000V AC / 1,500V DC |
| Isilinganiso samanje | Kufika ku-6,300 a |
| I-Short-Circuit Passtand | Kufika ku-100 ka |
| Ukuqhekeka komthamo | 25-100 Ka |
| Uhlobo lokufakwa | Kufakwe umoya (okuvame kakhulu) |
| Ukufaka | Ngaphakathi (kufakwe ikhabethe noma kufakwe edongeni) |
| Ukuhambisana namazinga | I-IEC 61439, IEC 60947, ANSI / NEMA |
I-LV vs MV Switchchgear: Uyini umehluko?
Ngenkathi i-LV ne-MV switchfuar ikhonza izindima ezifanayo zokuvikela, ziyehluka ekusebenzeni kwamandla kagesi, ekwakhiweni nasekusetshenzisweni:
- I-Voltage Range: I-LV isebenza <1kv;
- Ukwahlukanisa: I-LV imvamisa isebenzisa umoya;
- Isikali sokufaka: Amaphaneli e-LV ahlangana futhi alungele ukusetshenziswa kwangaphakathi
- Izindleko nokulungiswa: Amasistimu we-LV ngokuvamile abiza kakhulu futhi adinga ukulungiswa okuncane okujwayelekile
Ungayikhetha kanjani i-LV Switchchgear efanele
Ukukhetha i-LV switchgear kubandakanya ukuhlola zombiliIzidingo Zobuchwepheshena-Izimo zesayithi:
- Ukuhlaziywa komthwalo: Qonda izimfuno zamanje neziqhubekayo zamanje
- Indawo ezungezile: Umswakama, uthuli, kanye nokushisa kuthonye ukukhetha kokufakelwa kokufakelwa
- Izidingo Zokwanda: Imiklamo ejwayelekile inikeza ukuguquguquka kwezithuthukisi ezizayo
- Izici Zokuphepha: Isithonjana se-ARC Flash, Isilinganiso se-IP, izindlela zokuxhumanisa
- Ukuqinisekiswa: Qinisekisa ukuhambisana ne-IEC, i-ANSI, noma amazinga endawo
Imikhiqizo ephezulu efanaI-Legrand,Idlina, futhiIshaniselaNikeza amathuluzi okukhetha kanye nemihlahlandlela yezobuchwepheshe ukusekela ukucushwa okuhle.
Imibuzo ebuzwa njalo (i-FAQ)
I-A1: Ngenkathi iningi le-LV Gear lenzelwe ukusetshenziswa ngaphakathi, amayunithi afakwe ngokukhethekile anama-IP54 + angafakwa ngaphandle ngokuvikelwa kwemvelo.
I-A2: Ngokulungiswa okufanele, i-LV switchgear ingahlala iminyaka eyi-15-30.
A3: Yebo.
I-LV switchgear yakha umgogodla wengqalasizinda kagesi ephansi.
