Kokuxhuma CTs. zikagesi CTs

Abaguquli iingcinga kagesi. Eyona njongo iphambili ukuyiguqula ukuba DC. Le nkqubo kwenziwa yoqheliso electromagnetic. Ukuza kuthi ga ngoku, ukusika up amandla kunye ukubetha abaguquli.

Kwakhona kukho iintlobo ezininzi imifuziselo ngokwahlukana. Izinto zokubala, ke, yahlulwe abangabodwa-phase, kwisigaba-mbini kunye ontlantlu-ntathu. Ngqo uqhagamshelwano sombane uya kuba nefuthe uhlobo, amandla kunye nohlobo sokubala.

Xhulumanisa kwi imitha ezi-

Idibanisa current ukuba imitha kwisigaba enye jikelele kwenziwa ngokusebenzisa transistor. Kulo mzekelo, zidlala enkulu ntshikilelo indima parameter. Xa siqwalasela transformer ukubetha 220/220 V, ngoko ukudibanisa sihlelwa kuko i ray le transistor. Uthe tip adaptha iyafuneka.

Ukunciphisa nezihlandlo ukusetyenziswa iintlobo ezahlukeneyo capacitors. Ukuza kuthi ga ngoku, imodeli ixhaphakileyo kuthathwa ukuba capacitive. Noko ke, izixhobo analog nabo banelungelo lokuba khona. Ngqo ohlanganisa converter lwenziwa emva kokuhlola luvukelo transistor ezimbi.

Indlela ukudibanisa kwi counter kwisigaba-amabini?

Xhulumanisa kwi kwisigaba-ezimbini imitha sombane yangoku ivame kufezwa transistor latitudinal. Noko ke, xa sithetha ngayo ukunciphisa imifuziselo ukuya 220, ukuba kuphela kuhlangene capacitors kunye conductivity i parameter enkulu. Transceiver kwiisekethe lisetyenziswe ngokufuthi. Ngenxa uphazamiso magnetic ukuba balwe kakuhle.

Ukuze ukuba transistor unembinana nje kuphela sindisa ezingephi, esi somfanekiso esetyenzisiweyo. Converters yoqhagamshelo ingafumaneka kwi uhlobo engundoqo analog. Ipharamitha uxhathiso negative kulo mzekelo mayingagqithi ohms 60.

Xhulumanisa kwi imitha ontlantlu-ntathu

Idibanisa kwi abaguquli counter yangoku yale hlobo lwenzeka ubukhulu becala kusetyenziswa transistor yedijithali. Xa iivenkile ke zinikwa parameters ezahlukeneyo conductivity. Xa siqwalasela ukubetha kwentliziyo ontlantlu-ntathu sombane ngoku, kule meko iyavakala ukubeka nje transducer zoqhagamshelwano-mbini.

Ukwenzela ukuphepha ukusilela kwenzeka kwisiphaluka kusetyenziswa capacitors vysokoemkostnye. uxhulumaniso oluthe ngqo yokubala ngokusebenzisa ziliminxe.

Scheme linear transistor

Ukuqhagamshela transformer yangoku nge transistor yomgama inokwenzeka kuphela xa usebenzisa modulators. Kulo mzekelo, abaguquli umbane kuba uxhulumaniso ayilifaneli ayintsokothanga. Ngqo iadaptha kufanelekile ukukhetha qhagamshelana-mbini. Kule lokuguqulela, iingcali ezininzi sicebisa ukuba ufake i inverter. Kufuneka ibekwe phezu transistor. Noko ke, uxhathiso ezigxekayo le sekethe uvavanywa phambi kokuba. Isicwangciso eqhelekileyo Ohms 55. Egqithayo ithi drive imvelaphi inyuselwa khona amanzi aphantsi.

uqhagamshelo transformer ngokusebenzisa transistor operation

Udibaniso lwe transistor nge lo msebenzi kufuneka wenziwe kuphela imitha kwisigaba esinye. iimpawu nesiguquli kulo mzekelo, akukho indima ekhethekileyo ukudlala. Ingxaki ngamanye amaxesha kunye nokwandisa frequency Converter. Capacitors zisetyenziswa kuphela kwisekethe evulekileyo. rate conductivity kufuneka alingane hayi ngaphantsi kwe microns-6.

Kufuneka kwakhona sinikele ingqalelo ekumiseleni ukuxhathisa ezimbi. Ukuba udlula ohms-50, ngoko ke emngciphekweni omkhulu drive nobushushu. Kulo mzekelo, iswitshi uya zilungele nkqu qha-mabini.

Ukuqhuba ne umqhubi relay

Idibanisa nge a version wire edluliselwe kuqonde. iimpawu nesiguquli kulo mzekelo, akukho indima ekhethekileyo ukudlala. Kulo mzekelo, i-adaptha iyafuneka. Capacitors iingcali ezininzi Siyaleza ukubeka uhlobo analog. Le transducer, nayo, kufuna amanzi aphantsi. Ngenxa yale ingxaki kubekho rhoqo zenzeka manqaphanqapha. Ngaphambi kokuba ubeke capacitor ivavanywa ukumelana elibi transformer. Uthe parameter kufuneka ohms ngaphantsi kwama-60. Kungenjalo, le capacitor ayinako ukuma.

Idibanisa nge transceiver

Ukusebenzisa counter uqhagamshelo transceiver nge current lwenziwa converters-ended single. Ukuba sicinga abaguquli ukubetha, lo transistor akufuneki analog. Ukongezelela, iiswitshi wasebenzisa yaphela olulodwa. Kulo mzekelo, i conductivity yangoku kufuneka ibe kwinqanaba microns-5. Xa sincokola ngayo bucala abaguquli, ukuba nje iimitha ezi-ezifanelekileyo. Ipharamitha Umda frequency ezikwi, ngokuqhelekileyo akukho ngaphezulu kwama-6 Hz. Converters imifanekiso zidla efakwe ephantsi-ukuxhathisa. Ngenxa kule ukungaphumeleli abaguquli kwenzeka ngamaxesha. Kulo mzekelo, ukuya iadaptha umthwalo omkhulu ungekho.

Kufuneka kwakhona ingqalelo ngokwahlukileyo uxhulumaniso abaguquli inyathelo-phantsi. Baya kuba iklasi kwezixhobo ophezulu ombane. Kulo mzekelo, ucwangciso yesekethe operation frequency kunokuba ukuya ku 80 Hz. , Le inverter kufuneka kufakelwe single-contact ukujongana nayo. Transistors ke ngoko kusetyenziswa umqadi engundoqo. Ukuba sithetha ulungiso 500, ukongeza kwi counter wabeka somfanekiso encinane. Lifanele ukunyusa umbane.

Ukusebenzisa thyristors abangabancedani

Ngenxa thyristors uqhagamshelwano counter abangabancedani ngokusebenzisa abaguquli langoku kuphela xa kwincam-uhlobo converters athi yenziwe. Noko ke, xa sithetha abaguquli ukubetha, ungasebenzisa uguqulelo kabini-ekupheleni. Kwezinye iimeko, oku akuvumelekanga ukuyenza. Le transistors asetyenziswa wesekethe ngaphandle somfanekiso. Kulo mzekelo, yokudibanisa imitha lwenzeka esebenzisa umcephe wokunyusa. Kwakhona, iingcali ezininzi bacebisa lokufaka modulators semiconductor ukwandisa rhoqo.

Isicelo unijunction zener

Unijunction zener odumileyo ngenxa yokuba bakwazi ukusebenza kakuhle kunye nakumaziko aguqula amandla. Converters le njongo ekhethiweyo yaphela olulodwa. Ukuba sicinga sokwahlula sombane 220/220 B, ngoko kule meko somfanekiso kufuneka sifakwe kufuphi ekhawuntarini. Modulators zisetyenziswa ngokuqhelekileyo analog. Noko ke, abanye bakhetha ukuguqulwa amaza.

Xa ombane umda we-300 V zithathwa ukuba ndisebenze ngempumelelo ngakumbi. nabo kakhulu ukunciphisa ingozi yokuba ukungaphumeleli transformer. zokubala for olulodwa uqhagamshelo isigaba senziwa ngalo umcephe wokunyusa. Kulo mzekelo, i ombane olunokuxhasa kuphela uhlobo wire-mbini.

Udibaniso nge comparators ezisezantsi-frequency

Idibanisa kwi CT counter ngamanye amaxesha kwenziwa comparators njalo. Ukucutha uxinzelelo yokuma kwabo kwi-500 V. Ngoko, abaguquli amandla ukudibanisa ingangeni elungileyo. Noko ke, analogue ukunciphisa nazo zinokusetyenziswa. Oku kuya kufuna ezikumgangatho ophezulu olunye-contact transducer. Ngaphandle ray transistor ayikwazi ukukwenza kule meko. Ukwanda ezinomlinganiselo le inverter kunokwenzeka kuphela ngokusebenzisa somfanekiso. kwisiphaluka loo utshintsho kufuneka phambi kokuba imitha.

Ukusebenzisa uqhagamshelwano lwetshiphu emsebenzi-frequency comparator

Emva comparators sentlalo sombane aphezulu yangoku ingaqhuba kuphela kwisigaba ezithathu-manzi. Kulo mzekelo, i transistors bavumelekile ukuba basebenzise kuphela uhlobo ngemagnethi. Uhanjiso Ipharamitha yangoku kwisekethe awudluli microns 7. Amaza ukusebenza kulo mzekelo ilingana-avareji ye-80 Hz. Ukwandisa uvakalelo usebenzisa converters kabini-yaphela.

Ray transistors asetyenziswa kunqabile, ekubeni ukuphazamisana magnetic Bakwazi kakubi. Ukuba sithethe inyathelo-phantsi sombane, uqhagamshelo yabo kwenzeka kuphela modulator enamandla. Nangona kunjalo, phambi kokuxhuma uqinisekise uxhathiso zingafanelekanga kwisekethe. Ekugqibeleni, mayingagqithi ohms-50.

Yokuqhuba tetrode njalo

tetrodes Ukusoloko kwi kwikhonkco ayiniki Converter ngokutshiswa, kwanokuba ke amaza umda kwe 80 Hz. Kulo mzekelo, oku kuxhomekeke kuhlobo transformer. Ukuba sithethe malunga izixhobo ngamandla, zombini nga ngokukhuselekileyo ukuthatha incam utshilo. Converters idla ngokusetyenziswa kule analog. Conductivity nabo kufuneka ungabi ngaphantsi kwe microns-7.

Uxhathiso esibi kwisekethe mayingagqithi ohms 60. Ukuba sithethe inyathelo-phantsi sombane, ukuze izakubanodibaniso ngokusebenzisa tetrode kuphela kweemitha ezi-. Kulo mzekelo, i transistor iyasetyenziswa radiotherapy. Ngenxa yoko, wabeka modulators otshangatshangiswayo. ombane output parameter ayinakuba ngaphezu 200 V.
