Ukuqalisa
I-Switchchear ephansi ye-voltage (LV)kuyinto ebalulekile kwizinhlelo zamandla kagesi, ikakhulukazi ezisetshenziselwa ezentengiso, zokuhlala, kanye nezimboni. Yini ivolumu ye-LV switchgear?Ukuqonda impendulo kubalulekile ekuqinisekiseni ukuhambisana, ukuphepha, kanye nokusebenza kahle kunoma yiluphi uhlelo lokusabalalisa amandla.
Lo mbhalo uhlola uhla lwe-voltage olujwayelekile lwe-LV switchchear, izinhlelo zayo zangempela zomhlaba, ukuthi iqhathanisela kanjani izixazululo eziphakathi neziphezulu ze-voltage, nokuthi ungalukhetha kanjani uhlelo olufanele ngokususelwa kwizidingo zephrojekthi.
Yini i-LV switchgear?
I-Voltage Voltage VolvageKubhekiswa kwimishini kagesi eyenzelwe ukuvikela, ukulawula, nokuhlukanisa amasekhethi kagesi asebenza kuma-voltages aze afike ku-1000 volts ac (ukushintshanisa kwamanje IKhomishini Yezwe Yama-Electrotechnical (IEC 61439), Isigaba esiphansi se-voltage sihlanganisa izinhlelo ezisebenza noma ngaphansi kwale mikhawulo ye-voltage.
Lolu hlobo lwe-switchchear lusetshenziselwa:
- Sabalalisa Ngokuphepha Amandla Kagesi
- Kuphazamisa amaphutha wephutha
- Ukwahlukanisa amasekethe ngesikhathi sokulungiswa
- Vikela abasebenzi kanye nemishini
Izakhi ezibalulekile ze-LV switchchear
- Abaphula umjikelezo (MCB, MCCB, ACB)
- Amabhasi
- Abaxhumene nabo
- Umfula
- Ukunqamula ukushintshwa
- Kudlulisela namadivayisi okuvikela
Ngayinye yalezi zinto idlala indima ethile ekuqinisekiseni uhlelo luphephile, lusebenza kahle futhi luyasabela ezimweni ezingejwayelekile.
Uhla lwe-voltage ejwayelekile ye-LV switchchear
Igama elithi "voltage eliphansi" lingahluka kancane ngokuya ngamazinga aphesheya, kepha ezimeni eziningi,I-LV switchgear isebenza ngaphakathi kwamabanga alandelayo we-voltage:
- Izinhlelo ze-AC: 50v kuya ku-1000V
- Amasistimu we-DC: 120V kuya ku-1500V
Kuzinhlelo zokusebenza ezisebenzayo, amazinga ajwayelekile kagesi we-LV Switchgear afaka:
- I-230 / 400VUkuze uthole ukusetshenziswa kwezentengiso nokuncane
- I-415vEkuhlelweni kwezimboni ezintathu zezimboni
- I-480VIzinhlelo ezivame ukusetshenziswa ezimbonini zaseNyakatho Melika
- I-690VEzindaweni ezikhethekile zezimboni njengezimayini noma imishini emikhulu
Lawa mazinga kagesi ahambelana nezinhlelo ezijwayelekile zokuhlinzekwa emazweni ahlukahlukene nasezifundeni.
Izicelo kanye nokusebenzisa amacala
I-LV switchgear iwubucayi ekusakazweni kwamandla ngenxa yezici zayo zokuvumelana nezimo.
Amacala Wokusetshenziswa Okujwayelekile

- Izinto eziguqukayo nezisetshenziswa kabusha
Amazinga aphesheya afanaIEC 61439-1na-IEEE C37.20.1Nikeza imihlahlandlela ephelele yokuhlola, ukuklama, kanye nokwenza kwe-LV Switchgear.
Izici zobuchwepheshe kanye nokucaciswa
Ake sihlole imininingwane ebalulekile yezobuchwepheshe echaza ukusebenza kwe-LV switchgear:
| Specification | Inani elijwayelekile |
|---|---|
| Amandla kagesi | Kufika ku-1000V AC / 1500V DC |
| Ubuningi bokwenzeka | 50/60 Hz |
| Kukalwe manje | I-100a kuya ku-6300a |
| Isifunda esifushane sokumelana | 25Kaya ku-100ka |
| Isigaba sokuvikelwa | IP42 kuya ku-IP65 (kuya ngokubiyela) |
| Ukuhambisana okujwayelekile | IEC 61439, ANSI C37, UL 891 |

Umehluko ovela ku-medtage voltage switchchear
Kubalulekile ukuthi ungahlanganisi i-LV switchgear enomlingani wayo ophakathi noma ophezulu we-voltage.
| Uhlobo | I-Voltage Range | Ukusetshenziswa okujwayelekile |
|---|---|---|
| I-Low Voltage (LV) | ≤ 1000V AC / 1500V DC | Izakhiwo, izimboni, izikhungo zedatha |
| I-VoLtage Ephakathi (MV) | I-1KV - 36KV | Ukufakwa esikhundleni, amapulazi omoya, ukwelashwa kwamanzi |
| I-High Voltage (HV) | > 36kV | Imigqa yokuhambisa, amagridi wosizo |
I-LV switchgeariphephe, kulula ukuyifaka, futhi ibiza kakhulu, kantiIzinhlelo ze-MV / HVdinga ukufakwa okwengeziwe, ukusebenza okukude, kanye nokulondolozwa okukhethekile.
Ungayikhetha kanjani i-LV Switchchgear efanele

Imibuzo ebuzwa njalo (i-FAQ)
I-voltage evamile ekalwe nge-LV switchgear imvamisaI-230 / 400VNgezinhlelo ezizodwa nezinezigaba ezintathu, yize kungakhuphukelaI-1000v ACnomaI-1500V DCNgokuya ngohlelo lokusebenza namazinga wesifunda.
Yebo. Imiphumela ye-Solar Inverter,Izinhlelo Zokugcina Ibhethri (Bess), futhiIziteshi zokushaja ze-EV, ikakhulukazi ekucushweni kwe-DC kuze kufike ku-1500V.
Uma uhlelo lwakho lusebenzaNgezansi kwe-1000v AC, I-LV switchgear ifanelekile. ukufakwa,izitshalo ezinkulu zezimboni, nomaAma-feeders wegridi avuselelekayo-I-MV noma i-HV switchgeariyadingeka.
Imicabango yokugcina
UkuqondaUhla lwe-Voltage Switchchgear LVkubalulekile ekuqinisekiseni ukuphepha kukagesi nokusebenza. I-1000V AC noma i-1500V DC, lesi sigaba se-switchgear silungele ngokuphelele izakhiwo zesimanje, amafektri, kanye nezixazululo zamandla.
Noma ngabe uklama uhlelo olusha lwamandla noma uthuthukise oludala, ukhetha i-LV switchgear esekelwe ezilinganisweni zamanje, umthamo wezemvelo, imvelo, kanye nokuhambisana okujwayelekile kunganciphisa kakhulu phansi futhi kuthuthukise ukuphepha.
Ngaso sonke isikhathi uthintana nabaqeqeshiwe abaqeqeshiwe futhi babhekise kubakhiqizi abathembekile ukwenza izinqumo ezinolwazi ezivezwa isikhathi.
