Idizayini evamile ye-PCB yamanje ayidluli ku-10 A, noma ngisho no-5 A. Ikakhulukazi ezintweni zikagesi zasendlini nabathengi, ngokuvamile ukusebenza okuqhubekayo kwamanje ku-PCB akudluli ku-2 A.

Indlela 1: Isakhiwo ku-PCB

Ukuthola amandla amanje e-PCB, siqale siqale ngesakhiwo se-PCB. Thatha i-PCB enezingqimba ezimbili njengesibonelo. Lolu hlobo lwebhodi lesifunda luvame ukuba nesakhiwo sezendlalelo ezintathu: isikhumba sethusi, ipuleti, nesikhumba sethusi. Isikhumba sethusi yindlela okudlula kuyo i-current and signal ku-PCB. Ngokolwazi lwe-physics yesikole esiphakathi, singakwazi ukwazi ukuthi ukumelana kwento kuhlobene nempahla, indawo enqamula izingxenye, kanye nobude. Njengoba i-current yethu isebenza esikhumbeni sethusi, i-resistivity ihleliwe. Indawo ye-cross-sectional ingathathwa njengobukhulu besikhumba sethusi, okuwugqinsi lwethusi ezinkethweni zokucubungula ze-PCB. Imvamisa ukujiya kwethusi kuvezwa ku-OZ, ukujiya kwethusi okungu-1 OZ kungu-35 um, u-2 OZ kungu-70 um, njalonjalo. Khona-ke kungaphethwa kalula ngokuthi uma i-current enkulu izodluliswa ku-PCB, izintambo kufanele zibe zifushane futhi zibe nkulu, futhi ukuqina kwethusi kwe-PCB, kungcono.

Kubunjiniyela bangempela, alikho izinga eliqinile lobude bezintambo. Imvamisa esetshenziswa kubunjiniyela: ukujiya kwethusi / ukukhuphuka kwezinga lokushisa / ububanzi bentambo, lezi zinkomba ezintathu zokukala umthamo wamanje wokuthwala webhodi le-PCB.

Isipiliyoni sezintambo ze-PCB siwukuthi: ukukhulisa ukujiya kwethusi, ukunweba ububanzi bezintambo, nokuthuthukisa ukuchithwa kokushisa kwe-PCB kungathuthukisa umthamo wamanje wokuthwala we-PCB.

Ngakho-ke uma ngifuna ukusebenzisa i-current ye-100 A, ngingakhetha ugqinsi lwethusi lwe-4 OZ, ngisethe ububanzi bokulandelela bube ku-15 mm, imikhondo enezinhlangothi ezimbili, bese ngengeza isinki lokushisa ukuze nginciphise ukukhuphuka kwezinga lokushisa kwe-PCB futhi ngithuthukise. ukuzinza.

Indlela yesibili: itheminali

Ngaphezu kokufakwa kwezintambo ku-PCB, izikhala zezintambo nazo zingasetshenziswa.

Lungisa amatheminali amaningana angakwazi ukumelana no-100 A ku-PCB noma igobolondo lomkhiqizo, njengamantongomane okubeka phezulu, amatheminali e-PCB, amakholomu ethusi, njll. Bese usebenzisa amatheminali afana nezigaxa zethusi ukuxhuma izintambo ezingamelana no-100 A kumatheminali. Ngale ndlela, imisinga emikhulu ingadlula ezintanjeni.

03

Indlela yesithathu: ibha yebhasi yangokwezifiso

Ngisho nemigoqo yethusi ingenziwa ngezifiso. Kuwumkhuba ovamile embonini ukusebenzisa imigoqo yethusi ukuthwala imisinga emikhulu. Isibonelo, ama-transformer, amakhabhinethi eseva nezinye izinhlelo zokusebenza zisebenzisa imigoqo yethusi ukuthwala imisinga emikhulu.

Indlela yesi-4: Inqubo ekhethekile

Ngaphezu kwalokho, kunezinqubo ezithile ezikhethekile ze-PCB, futhi ungase ungakwazi ukuthola umkhiqizi e-China. I-Infineon inohlobo lwe-PCB enomklamo wezingqimba zethusi ezinezingqimba ezi-3. Izendlalelo ezingaphezulu neziphansi ziyizingqimba zezintambo zesignali, kanti ungqimba oluphakathi luyingqimba yethusi enogqinsi luka-1.5 mm, olusetshenziswa ngokukhethekile ukuhlela amandla. Lolu hlobo lwe-PCB lungaba lula ngosayizi oluncane. Ukugeleza ngaphezu kwe-100 A.
