Ukuqonda i-Current Transformer Ratio
Iyintoni iRatio yeTransformer yangoku
Ungabona amanani anje nge-100:5 okanye i-200:1 kwi-transformer yangoku. La manani abonisaumlinganiselo we-transformer yangoku. Lo mlinganiselo ukuxelela ukuba umbane wehliswa kangakanani ukusuka kwintambo ephambili ukuya kwisixhobo sokulinganisa. Umzekelo, ukuba umlinganiselo yi-100:5, yonke i-100 amps kwintambo ephambili ijika ibe yi-5 amps kwisekethe yokulinganisa. Oku kwenza kube lula kwaye kukhuselekile ukujonga umbane omkhulu. I-Maliotech LMZ Series isebenzisa umlinganiselo we-transformer wamandla ombane ochanekileyo kakhulu. Oku kukunceda ufumane ukufundwa okuhle onokukuthemba.
Indlela Esebenza Ngayo Umlinganiselo
I-transformer yamandla ombane yehlisa amandla ombane ukuze ukwazi ukuwulinganisa ngokukhuselekileyo. Nantsi indlela esebenza ngayo:
- I-primary winding iqhagamshela kwi-main wire kunye ne-current.
- Umsinga okwi-primary winding wenza i-magnetic field embindini.
- Ukujika kwesibini kufumana le magnethi kwaye kwenze umsinga omncinci.
- Ubungakanani bombane kwi-secondary winding buxhomekeke kumlinganiselo ophakathi kwe-windings.
Oku kukuvumela ukuba usebenzise iimitha eziqhelekileyo ukujonga imisinga emikhulu ngaphandle kwengozi.
Ichaziwe iReturns Ratio
Umlinganiselo wokujika linani lee-loops kwi-primary winding xa kuthelekiswa ne-secondary winding. Lo mlinganiselo ulawula ukuba umbane uphantsi kangakanani. Ungasebenzisa le fomula ukufumana umlinganiselo we-current transformer:
