I-Maliotech LMZ Series iyi-transformer yamanje enhle yokusetshenziswa ngokuphephile nangokunembile.
Ukuqonda Isilinganiso Sokuguqulwa Kwamanje
Iyini Isilinganiso Sokuguqulwa Kwamanje
Ungase ubone izinombolo ezinjengo-100:5 noma u-200:1 ku-transformer yamanje. Lezi zinombolo zibonisaisilinganiso se-transformer yamanjeLesi silinganiso sikutshela ukuthi ugesi wehliswa kangakanani kusukela kuntambo eyinhloko kuya kudivayisi yokulinganisa. Isibonelo, uma isilinganiso singu-100:5, wonke ama-amps ayi-100 kuntambo eyinhloko aphenduka ama-amps ayi-5 kusekethe yokulinganisa. Lokhu kwenza kube lula futhi kuphephe ukuhlola ugesi omkhulu. I-Maliotech LMZ Series isebenzisa isilinganiso sogesi esinembile kakhulu. Lokhu kukusiza ukuthi uthole ukufundwa okuhle ongakwethemba.
Indlela Isilinganiso Esisebenza Ngayo
I-transformer yamanje yehlisa i-current ukuze ukwazi ukuyilinganisa ngokuphephile. Nansi indlela esebenza ngayo:
- Ukugoqa okuyinhloko kuxhuma kuntambo eyinhloko kanye nogesi.
- Ugesi ojikeleza kakhulu wenza insimu yamagnetic enkabeni.
- Ukugoqa kwesibili kuthola le nsimu yamagnetic futhi kwenze ugesi omncane.
- Inani lamanje ekujikeni kwesibili lincike esilinganisweni esiphakathi kwama-winding.
Lokhu kukuvumela ukuthi usebenzise amamitha ajwayelekile ukuhlola imisinga emikhulu ngaphandle kwengozi.
Isilinganiso Sokujika Sichaziwe
Isilinganiso sokujika siyinani lama-loops ekugoqeni okuyinhloko uma kuqhathaniswa nokugoqa kwesibili. Lesi silinganiso silawula ukuthi ugesi wehliswa kangakanani. Ungasebenzisa le fomula ukuthola isilinganiso somshini wokuguqula wamanje:
| Okuguquguqukayo | Incazelo |
|---|---|
| Ap | Ama-amps ayinhloko |
| As | Ama-amps esibili |
| Np | Inani lamajika ayinhloko |
| Ns | Inani lokujika kwesibili |
Ifomula ithi: isilinganiso se-transformer yamanje = Ap / As. Uma wazi inani lamajika, ungasebenzisa futhi i-Np / Ns. I-Maliotech LMZ Series isebenzisa isilinganiso samajika ngokucophelela. Lokhu kuqinisekisa ukuthi izilinganiso zakho zilungile futhi ziphephile.
Indlela Yokufunda Isilinganiso se-CT
Ukuthola Izimpawu Zesilinganiso Se-CT
Ungabonaisilinganiso se-transformer yamanjekuphrintiwe kudivayisi. Abakhiqizi bafaka lezi zinombolo kulebula enamathiselwe ebhokisini. Bheka izinombolo ezifana no-"100/5" noma "300:5" eduze kwama-terminal noma ohlangothini. Lezi zinombolo zibonisa umehluko phakathi kogesi osesekethe eyinhloko kanye nogesi ophuma ohlangothini lwesibili.
Uma usebenzisa i-Maliotech LMZ Series, uzobona izimpawu ezicacile ze-terminal. Uhlangothi oluyinhloko luphawulwe ngokuthi P1 no-P2. Uhlangothi lwesibili luphawulwe ngokuthi S1 no-S2. Lawa malebula akusiza ukuthi uxhume izintambo ngendlela efanele. Lokhu kuqinisekisa ukuthi ukulinganisa kwakho kulungile. Njalo bheka lezi zimpawu ngaphambi kokufaka noma ukusebenzisa i-transformer yamanje.
Icebiso: Uma ungakuboni ukumakwa kwesilinganiso, hlola incwadi yemiyalelo yomkhiqizo noma ishidi ledatha. Izinkampani ezifana neMaliotech zihlala zinikeza lolu lwaziukufakwa okuphephile.
Ukuhumusha Izinombolo Zesilinganiso se-CT
Uma ufunda isilinganiso se-CT, ubona izinombolo ezimbili ezine-slash noma ikholoni. Inombolo yokuqala ikhombisa ugesi omningi ohlangothini oluyinhloko olungawuphatha. Inombolo yesibili ikhombisa ugesi ophumayo ohlangothini lwesibili lapho ugesi oyinhloko ugcwele. Isibonelo, uma ubona u-100/5, kusho ukuthi ama-amps ayi-100 kugesi oyinhloko azonikeza ama-amps ayi-5 kugesi oyinhloko.
Lesi silinganiso sikusiza ukuthi ufanise i-transformer yamanje nesistimu yakho. Uma usebenzisa i-300:5 CT futhi isekethe yakho eyinhloko inama-amps angu-150, eyesibili izokunikeza ama-amps angu-2.5.
