Chii chinonzi VAC muinjiniya yemagetsi?
Zviri mukati
Iwe unoda kuziva here kuti VAC inomirirei mumashoko emagetsi? Ini ndiri certified electrician uye ini ndichavhara izvi zvakadzama mune pfupi chinyorwa pazasi.
Unogona kuona 110VAC kana 120VAC yakanyorwa pamidziyo yakawanda yemagetsi.
Kazhinji, VAC rinongori izwi rinoshandiswa muinjiniya yemagetsi ye AC volts. Iwe unogona kunge uchiziva nezve DC volts; ndiyo DC voltage. Saizvozvo, VAC inomiririra AC voltage. Chinhu chega chaunofanirwa kuziva ndechekuti zvese VDC neVAC zvinomiririra voltages.
Ramba uchiverenga kuti uwane tsananguro yakadzama.
Zvese zvaunoda kuti uzive nezveVAC
Nyika zhinji muNorth America dzinoshandisa 110 kana 120 VAC. Uye iwe unogona kuona izvi mamaki pane zvimwe zvigadzirwa zvemagetsi zvakaita semakomputa, zvinoshandura zvinoshandura, uye madhijitari multimeter. Asi unoziva zvarinoreva here?
VAC ndiro izwi rinoshandiswa kureva AC volts. Saka hakuna chinhu chinonzi AC simba. Ingori AC circuit voltage.
Nekudaro, kuti uzvigadzirise, unofanirwa kunzwisisa mutsauko uripo pakati peVAC neVDC.
Chii chinonzi VDC uye VAC?
Kutanga, iwe unofanirwa kuziva nezve DC uye AC kuti unzwisise aya mazwi maviri.
Direct current (DC)
DC simba rinoyerera kubva kune yakaipa kusvika kumagumo akanaka. Kuyerera uku hakuna unidirectional, uye bhatiri remota muenzaniso unozivikanwa.
Alternating current (AC)
Kusiyana neDC, simba reAC rinoyerera kubva kumativi ese. Semuyenzaniso, musekondi chero ipi zvayo, simba re AC rinoshanduka kubva pakuipa kuenda kune rakanaka uye kubva kune rakanaka kuenda kune rakaipa. Iyo huru magetsi inouya mumba mako ndiyo yakanakisa muenzaniso we AC simba.
V DC uye AC
Kana iwe uchinyatsonzwisisa AC uye DC simba, hapana chekunzwisisa nezveVDC neVAC.
Heino tsananguro iri nyore.
VDC inomiririra iyo DC voltage kukosha uye VAC inomiririra iyo AC voltage kukosha. Kana iwe ukatora digitaalinen multimeter uye ukanyatsoiongorora, unogona kuona ese ari maviri aya mamaki. Nekudaro, kana iwe uchida kushandisa zvigadziriso izvi mumultimeter, unofanirwa kuziva kuti ndeapi masekete anoshanda neDC voltage uye masekete ane AC voltage.
Ndingawane kupi VAC?
Nzvimbo zhinji dzeNorth America dzinoshandisa 110 kana 120 VAC kudzimba dzakajairwa. Unogona kuwana chiratidzo ichi pamidziyo yeAC. Zvisinei, kana zvasvika kuEurope vanoshandisa 220VAC kana 240VAC.
Kurumidza Zano: Iyo 120 V AC yekugovera voltage inosiyana kubva pa170 V kusvika zero. Zvadaro inosimuka zvakare ku170V. Semuenzaniso, kuchinjanisa ikozvino kunodzokorora ka60 musekondi imwe. Ichi ndicho chikonzero akawanda AC masosi ari 60Hz.
RMS voltage 120 V AC
Muchokwadi, 120V AC inochinjana kuenda ku170V uye inodonha kusvika zero. Iyi sine wave yakaenzana ne120 volts DC uye inozivikanwa seRMS.
Maitiro ekuverenga kukosha kweRMS?
Heino fomula yekuverenga RMS.
VRMS V=CHIKURU*1/√2
Peak voltage 170V.
Naizvozvo,
VRMS = 170*1/√2
VRMS = 120.21 V
Sei tichishandisa VAC?
Iwe ucharasikirwa nerimwe simba nguva dzose paunoedza kushandura simba kubva kune imwe fomu kuenda kune imwe. Nokudaro, kuderedza kurasikirwa kwesimba uku, majenareta anogadzira magetsi pamagetsi akakwirira uye anoaendesa nenzira yekuchinjanisa ikozvino.
Zvisinei, dzimba dzemazuva ose hadzidi magetsi emagetsi. Nekuda kweizvi, magetsi eAC anopfuura nepadanho-pasi transformer uye anogadzira yakaderera voltage yekushandisa pamba.
zvakakosha: Zvizhinji zvemagetsi hazvishande pamagetsi eAC. Pane kudaro, vanoshandisa low voltage DC simba. Naizvozvo, yakaderera voltage AC simba inoshandurwa kuita yakaderera voltage DC simba nebhiriji rectifier.
Tarisa zvimwe zvezvinyorwa zvedu pazasi.
- Kugadzira multimeter yebhatiri yemotokari
- Voltage inodonha bvunzo jenareta
- Nzira yekuedza bhatiri remotokari ne multimeter
