Indlela yokwenza ngokomthetho ugesi ngezandla zabo

Kusukela sihloko, uzofunda indlela yokwenza ugesi ukulungiswa ngezandla zakhe kusukela izinto ezazikhona. Ingasetshenziselwa empahleni amandla yasendlini, kanye nezidingo laboratory yethu siqu. DC umthombo voltage ingasetshenziswa ukuhlola amadivaysi ezifana edluliselwe isilawuli alternator yezimoto. Ngempela, lapho kuba khona isidingo ukuxilonga voltages ezimbili - volts 12 futhi bangaphezu kuka-16 Manje, cabanga netimphawu teluhlakasimo lweSitatimende kwamandla.

transformer

Uma idivayisi akufanele sisetshenziselwe wayeqamba NiCd amabhethri kanye namadivayisi yamandla aphezulu, asikho isidingo ukusebenzisa Transformers ezinkulu. Lwanele ukusebenzisa imodeli, amandla lapho kungekho Watts ezingaphezu kuka-50. Nokho, ukwenza adjustable ugesi ngezandla zabo, thatha kancane ukushintsha design of the Converter. Into yokuqala okudingeka ukunquma nalokho uhla voltage ushintsho okukhiphayo. Lokhu ipharamitha incike izici ugesi transformer.

Ake sithi ukhethe uhla 0-20 volts, ngakho kuzomele wenze isiqalo kulezi amagugu. I yesibili emazombezombe kufanele abe lo voltage okukhiphayo kushintshana ka 20-22 volts. Ngenxa yalokho, kokushiya eyinhloko transformer emazombezombe, phezu kwalo ukuqhuba yesibili emazombezombe. Yikuphi is etholakala eziyishumi ukubala inani elidingekayo ematfuba, slide voltage metering. Eyodwa kweziyishumi lesi silinganiso, - zinamandla ethathwe ikhoyili eyodwa. Ngemva ikhoyili yesibili, kubalulekile ukukhiqiza emhlanganweni wesifunda core coupler zizokwenziwa.

rectifier

Njengoba rectifier inhlangano angahle kulesinye sikhatsi asetjentiswe kanye diodes ngabanye. Ngaphambi kokwenza ngokomthetho ugesi, enze ukukhethwa zonke izingxenye zalo. Uma umfutho zamanje okusezingeni eliphezulu eMhlanganweni ekhishwa, uzodinga ukusebenzisa Semiconductors enamandla. Kuyinto efiselekayo ukufaka kwi aluminium radiators. Ukuze uhlelo, preference kufanele inikwe kuphela kwebhuloho, njengoba has a ukusebenza kahle kakhulu kunalokhu, ukulahlekelwa kancane voltage at ukulungisa kushintshana zamanje. kunconywa ukuba usebenzise wesifunda isigamu-wave, njengoba singasebenzi ephumelela kakhulu, okukhiphayo kukhona eziningi amanzi enyakaza ukuthi baphendukezele isignali futhi iwumthombo ukuphazamiseka umsakazo.

kuqiniswa futhi ukulungiswa iyunithi

Ukuze umkhiqizo isimame futhi umlamuli voltage buhlakaniphile ukusebenzisa LM317 microassembly. Eshibhile futhi kufinyeleleke kudivayisi ngayinye ivumela Ngemizuzwana ukuqoqa eliphezulu amandla Iyunithi enikeza adjustable ngesandla ukuthi. Kodwa isicelo yayo kudinga imininingwane eyodwa ebaluleke - Ukupholisa kahle. Futhi hhayi kuphela ngesimo kurediyetha yekwentiwa. Iqiniso lokuthi nemithethonqubo kanye voltage sinjalo kwenzeka ngesikhathi iphethini ethakazelisa kakhulu. eshiya Tinsita ncamashi voltage okuyinto edingekayo, kodwa input ngokweqile ngesikhathi input yayo siguqulelwa ukushisa. Ngakho-ke, akukho Ukupholisa kuyinto microassembly singenakwenzeka oyohlala isikhathi eside.

Thatha look at the umdwebo, akukho edangalisayo. okukhipha Ubude emihlanganweni emikhulu emithathu, voltage lwesithathu sisetshenziswa, it esuswa yesibili, futhi owokuqala iyadingeka ukuxhuma amandla supply lokususa. Kodwa lapha kukhona sici encane - uma zihlanganisa phakathi inetha kanye ukuphela lokuqala ukumelana zenhlangano, kuba nokwenzeka ukuba afeze ukulungiswa we voltage okukhiphayo. Ngaphezu kwalokho, amandla supply ezilungisiwe ngezandla Ungashintsha voltage okukhiphayo njengoba ngokushelela noma stepwise. Kodwa Uhlobo lokuqala ukulungiswa kuwusizo kakhudlwana, ngakho-ke isetshenziswa kaningi. Ukuze ekuqalisweni kubalulekile ukufaka ukumelana elibanzi 5 ohms. Ngaphezu kwalokho, phakathi kwenhlangano esibulalayo lokuqala nelesibili liyadingeka ukusungula Resistor unomphela ohms mayelana 500.

Isiphathi iyunithi wamanje kanye voltage

Yiqiniso, ukusebenzisa idivayisi kwaba elula kunazo, kubalulekile ukuba afeze ukulawula izici okukhipha - voltage namandla zamanje. Yakha ngokomthetho ugesi wesifunda ukuze ammeter likhona igebe phambili elihle futhi babe abazali voltmeter - phakathi wathi idivayisi okukhiphayo. Kodwa omunye umbuzo - onjani amathuluzi ngisebenzisa? Inketho elula - kangakanani ukufaka ezimbili LED-display, okuyinto ixhunywe wamanje-wesifunda kanye ammeter, eqoqwe kuma microcontroller olulodwa.

Kodwa amandla supply adjustable, ekhiqizwa ngezandla zabo, kungenzeka ukukhweza i-pair yama ezishibhile multimeters Chinese. Inzuzo ukudla kwabo zingaba ngokuqondile kudivayisi. Ungakwazi Ngokuqinisekile ukusebenzisa futhi ushayele izinkomba, kodwa kulokhu kubalulekile ukuba sifeze isikali esingaphezu kwesinqunywe for the Resistor onhlobonhlobo.

izindlu iyunithi

izindlu Manufactured engcono metal engasindi kodwa eqinile. Kuvele umgomo ekahle kungaba aluminium. Njengoba sekushiwo, isifunda yakhiwa ngokomthetho ugesi izakhi ukuthi ziyashisa. Ngenxa yalokho, kufanele izindlu ukukhwezwa ngaphakathi kurediyetha, okuyinto okwesikhathi ngekhono elingcono Ungaxhuma nomunye ezindongeni. Ithanda khona ukupholisa ngenkani. Ngenxa yale njongo, ungasebenzisa inkinobho ezishisayo ibhangqwe fan. Kuzomele ufake nabo ngqo kwi heatsink.
