Zothyola Circuit za 3P vs 3P+N vs 4P: Momwe Mungasankhire Choyenera？
Kusankha pakati pa 3P, 3P+N, kapena 4P Chotsegula Dera ndi chisankho chofunikira chomwe chimayenderana bwino chitetezo, kutsatira malamulo, ndi mtengo. Gwiritsani ntchito chitsogozo chosavuta ichi kuti musankhe bwino.
Lamulo Losavuta: Zonse Zokhudza Waya Wosalowerera
Kusankha kwanu kumadalira funso limodzi: Kodi waya wosalowerera amafunika chiyani mu dera ili?
Buku Lotsogolera Kusankha Mwachangu:
1. Gwiritsani ntchito 3P kokha pa katundu wa magawo atatu okha komanso wolinganizidwa (monga mota wa magawo atatu). Ndi yotsika mtengo koma siyimachotsa neutral, zomwe zingakhale chiopsezo cha chitetezo panthawi yokonza.
2. Gwiritsani ntchito 3P+N pa ma circuits ambiri okhazikika (magetsi, masoketi, katundu wosakanikirana). Iyi ndi njira yabwino komanso yotsika mtengo, chifukwa imachotsa bwino neutral kuti isawonongeke.
3. Gwiritsani ntchito 4P pokhapokha ngati kuli kofunikira: pa switch yayikulu, kusintha kwa ndalama (ATS), makina a IT, kapena pamene osalowerera ndale okha akufunika chitetezo chochulukirapo (monga ma harmonics oopsa).
Kusiyana Kwakukulu Kwafotokozedwa
| Mbali | Chothyola cha 3P | Chothyola cha 3P+N | Chothyola cha 4P |
|---|---|---|---|
| Kulumikizana Kosalowerera | Yolumikizidwa kosatha | Zingathe kuchotsedwa (zosatetezedwa) | Kutalikirana ndi kutetezedwa |
| Zabwino Kwambiri | Ma mota oyera a magawo atatu | Mabwalo ambiri omanga (chisankho chokhazikika) | Chosinthira chachikulu, inde, makina a IT |
| Mtengo | Wotsika kwambiri | Wocheperako | Wapamwamba kwambiri |
Cholakwika Chofala & Chokwera Mtengo
Musagwiritse ntchito ma 4P breakers kulikonse kuti mukhale "otetezeka kwambiri." Izi ndi zochulukirapo. Zimawonjezera mtengo ndipo zimatha kusokoneza mgwirizano woteteza wa makina anu, zomwe zingayambitse kusokonekera kwakukulu.
Malamulo Anu Atatu Abwino Kwambiri
•Lamulo Lodzipatula: Ngati dera lili ndi katundu wa gawo limodzi, muyenera kutha kuchotsa neutral. Sankhani 3P+N kapena 4P.
•Lamulo la Mtengo: Pa ma circuits okhazikika, 3P+N imapereka chitetezo chofunikira pamtengo wabwino kwambiri.
•Lamulo Lapadera: Sungani 4P pa ntchito zinazake, zovomerezeka monga switch yayikulu kapena makina a IT.
Masitepe Otsatira
Kusankha mipiringidzo ndi gawo loyamba. Kusankha kwathunthu kumafunanso kuwona mphamvu yosweka (Icu/Ics), kuchuluka kwa magetsi, ndi mtunda wolondola wa trip current wa katundu wanu (monga, kuthamanga kwa injini).
Dziwani: Bukuli limapereka mfundo zazikulu. Nthawi zonse tsatirani malamulo am'deralo okhudza mawaya ndipo funsani zofunikira za polojekiti kuti musankhe zochita zomaliza.
