Indlela yokwenza Regulator ngemandla yensimbi nokunamathisela ngomthofu? isilawuli Yamandla nokunamathisela ngomthofu ngezandla zabo: isikimu futhi imfundo

Amadivayisi ushintsha ezingeni voltage enikeziwe Ukushisa isici, hams avame ukusetshenziswa ukuvimbela ukwehluleka kwanoma ichopho nokunamathisela ngomthofu kanye nekhwalithi nokunamathisela ngomthofu. Amacebo ezijwayeleke kakhulu amandla nabalawuli zimumethe nokunamathisela ngomthofu dvuhpozitronnye contact ukushintshwa bese SCR amadivayisi elifakwe yokubeka. Lezi namanye amadivayisi ukunikeza ikhono ukhethe wayefisa voltage ezingeni. Namuhla kusebenzise izilungiselelo okuzenzela kanti endaweni yokukhanda.

Simple amandla Umlawuli nokunamathisela ngomthofu

Uma ufuna ukuthola nokunamathisela ngomthofu yensimbi 40 W 100 W singasetshenziswa phezu triac wesifunda BT 138-600. Isebenza ukusika igagasi sine nge. phuca izinga bafudumale lokushisa kungase kushintshwe besebenzisa Resistor-R1. Neon isibani ukhonza njengomdala inkomba. Ukuyibeka akudingekile. Ngezinye kurediyetha kuyinto triac olufakiwe BT 138-600.

izindlu

Lonke uhlelo kumele ngempela ufakwe izindlu avaliwe Kwe-dielectric Heating. Ukufisa ukuzenzela idivayisi miniature akufanele ezithinta ukuphepha uma uyisebenzisa. Qaphela ukuthi idivayisi esebenza emthonjeni voltage ka 220 V

SCR amandla Umlawuli nokunamathisela ngomthofu

Njengoba isibonelo, cabanga idivayisi, eyenzelwe nomthwalo Watts eziningana emakhulwini. Regulation ububanzi kwamandla ukalwe zedivayisi kuhluka 50% kuya ku-97%. Idivayisi isebenzisa ebambe KU103V SCR zamanje engaphansi milliampere.

Through the diode VD1 ngokukhululekile kudlule negative isigamu-wave voltage, ngaleyo ndlela athole ingxenye ka amandla ingqikithi insimbi nokunamathisela ngomthofu. It kungase kushintshwe VS1 SCRs ngesikhathi esihle isigamu-umjikelezo ngamunye. I-apharathasi esitshalweni antiparallel diode VD1. SCR positionally ilawulwa isimiso. I generator yakha pulses okokufaka ngaleso control electrode ehlanganisa R5R6C1 wesifunda ngokuchaza isikhathi unijunction Transistor.

Inani isibambo Resistor-R5 inquma nesikhathi esihle isigamu umjikelezo. isilawuli Amandla isikimu kudinga lokushisa ukuzinza kanye kangcono umsindo amasosha omzimba. Lokhu kungenziwa shunted ekuphatheni ushintsho Resistor-R1.

uchungechunge R2R3R4VT3

Generator voltage pulses fed 7b kanye nobude 10 ms ezime R2R3R4VT3 chain. -Daylight VT3 Transistor liyisici eliletha ukuthula. It kucushiwe ohlangothini reverse. Isifunda amandla okuyinto dissipates resistors-R2--R4, kuzoncishiswa.

Ukushayela amandla Umlawuli lunesidlali capacitor S1KM5, resistors - MLT R5 - SP 0.4. I Transistor ingasetshenziswa noma.

IBhodi kanye izindlu kudivayisi

Ukuze inhlangano yabantwana bakwa-kudivayisi efanelekayo ucwecwe fiberglass ibhodi 36 mm ububanzi kanye 1 mm obukhulu. Ukuze uma kwenzeka, ungasebenzisa noma yiziphi izinto, ezifana amabhokisi plastic noma izimo elinama nge ukwahlukanisa okuhle. Udinga isizinda ngaphansi izakhi ekuphambukeni. Ngenxa yale njongo ucwecwe kungaba solder amabili amantongomane 2.5 M ukuze izikhonkwane kuthiwa sicindezelwe ebhodini izindlu ngesikhathi inhlangano.

Okumbi SCRs KU202

Uma amandla yensimbi encane nokunamathisela ngomthofu, imigomo kungenzeka kuphela ungumthombo ongumngcingo isigamu-umjikelezo. Lowo lapho ukumelana voltage SCRs okungenani kancane kuka wamanje umthwalo. Temperature ukuzinza awutholakali ngokusebenzisa Regulator lawo mandla nokunamathisela ngomthofu.

Umlawuli isinyathelo-up

amadivaysi Iningi kuphela amandla phansi usebenza ekulinganiseni izinga lokushisa. Ukusingatha voltage kungaba kusuka 50-100%, noma 0-100%. amandla nokunamathisela ngomthofu bangase babe owanele uma ugesi 220 V noma ngezansi, isib, mkhulu vypayat ikhadi elidala uma kunesidingo.

Operating voltage is eshelelayo ngu capacitor electrolytic, anda izikhathi 1.41 futhi uyasondla insimbi nokunamathisela ngomthofu. amandla okuqhubekayo, kuyalungiswa phezu capacitor ifinyelela 310 V at 220 V Amandla elikhulu, izinga lokushisa Ukushisa ingatholakala ngisho at 170 V

nokunamathisela ngomthofu Inamandla akudingeki ukwandisa nabalawuli.

Izingxenye adingekayo isikimu

Ukuqoqa kusebenziseka kalula amandla Regulator for insimbi nokunamathisela ngomthofu ngezandla zakho, ungasebenzisa ebusweni obandayo indlela eduze esitolo esidayisa. Kudinga izingxenye ezincane obujwayelekile. Amandla Resistor olulodwa akumelwe ibe ngaphansi kuka-2 W, nabanye - 0.125 Watts.

Incazelo uhlelo yokuthuthukisa Regulator amandla

Esikhathini capacitor electrolytic C1 ilungiselelwe nge rectifier VD1 ibhuloho input. yokusebenza voltage waso akumele kube ngaphansi kuka-400 V Esikhathini FET IRF840 Umlawuli elise esezansi ingxenye. Njengoba kule divayisi ungasebenzisa yensimbi nokunamathisela ngomthofu kuya 65 W nge kurediyetha. Abakwazi sishiswa ngaphezu lokushisa oyifunayo, ngisho ne encishisiwe ugesi.

ukhiye ukuphathwa Transistor ubekwe DD1 chip, ekhishwa generator PWM kabani imvamisa kusethwa capacitor C2. isimame parametric ogibele amadivayisi C3, R5 VD4. Anakho DD1 chip.

Ukuvikela Transistor okukhipha isethwe kusukela VD5 inductance diode. It ayikwazi ukuhlelwa uma ukulawula amandla yensimbi nokunamathisela ngomthofu ngeke isetshenziselwe nezinye izinto zikagesi.

The kungenzeka esikhundleni izingxenye abalawuli

DD1 chip ungayithola enye by K561LA7. ibhuloho Rectifier wenziwe diodes eyenzelwe zamanje ubuncane 2A. kudivayisi IRF740 ingasetshenziswa njengenhlangano Transistor okukhiphayo. Isifunda akadingi okunamathiselwe, uma yonke imininingwane kulungile uma kwakungavunyelwe amaphutha inhlangano.

Amanye amadivayisi kungenzeka kwakuqeda voltage

uya nje circuit amandla Regulator for nokunamathisela ngomthofu, abasebenza symistors KU208G. Zonke ebuqilini babo kule epholisayo bese isibani neon, okuyinto siyashintsha ukukhanya yayo, singasebenza njengesisekelo esiqinile sokufinyelela inkomba amandla. ukulungiswa Okungenzeka - kusuka 0% kuya ku-100%.

Ngo ukungabikho triac noma thyristor ama kungenziwa KU202N isicelo. Le idivayisi evame kakhulu kokuba sebuningini ontanga. Ngekusetjentiswa yayo kungaba uhlanganiswe wesifunda ezisebenza ibanga 50% kuya ku 99% amandla.

core Ferrite kusukela intambo kukhompyutha ingasetshenziswa ukwenza iluphu ukukhokha ukuphazamiseka okungenzeka sizibulale triac noma thyristor.

scaler inkomba

Amandla Umlawuli nokunamathisela ngomthofu Ukudayela gauge kungaba kuhlanganiswe ukuze athole induduzo enkulu ngesikhathi ukusetshenziswa. Kwenze ngokuphazima kweso. Ubuningi imishini ubudala umsindo lingakusiza ucinge izakhi enjalo. Amadivayisi lula ukuthola ezimakethe zendawo kuwo wonke amadolobha. Nokho, uma onjalo is ekhaya ungenzi lutho.

Ngokwesibonelo, cabanga kungenzeka zokuhlanganisa ku umlamuli amandla Inkomba nokunamathisela ngomthofu M68501 umcibisholo kanye namamaki ezinombolo, okuyinto lihlelwe abalobi ubudala Soviet. Isici kulungiselelwa ukukhethwa Resistor-R4. Ngokuqinisekile kufanele sithathe iyunithi R3 ngaphezu, uma omunye inkomba esetshenziswa. Kuvele ibhalansi elifanele kumele obaphawuleka ongaphakeme amandla resistors nokunamathisela ngomthofu. Iqiniso lokuthi inkomba umcibisholo ukubonisa amandla nokuncishiswa by 10-20% ngesikhathi ukusetshenziswa langempela nokunamathisela ngomthofu yensimbi 50%, isb esingaphansi kwesigamu.

isiphetho

isilawuli Yamandla nokunamathisela ngomthofu ingalandwa, eqondiswa isethi imiyalelo kanye izihloko nge izibonelo ezingenhla yezingozi izifunda ezahlukene. Kusukela solder ezinhle, ecucuza futhi izinga lokushisa for Ukushisa element nokunamathisela ngomthofu izinga ixhomeke. amadivaysi eyindida ekulinganiseni noma aphansi ukuhlanganiswa diodes ingasetshenziswa inhlangano amadivayisi ezidingekayo ukuze alawule voltage engenayo.

Amadivayisi anjalo kabanzi ukuze kuncishiswe futhi ukwandisa awanikezwa Ukushisa elementi yensimbi nokunamathisela ngomthofu ku uhla kusuka 0% kuya ku-141%. Kuyinto elula kakhulu. Kukhona ithuba wangempela ukusebenza ngesikhathi voltages ngezansi 220 V Kwimakethe ukutholakala izimoto izinga, ifakwe Izilawuli ekhethekile. amadivaysi Factory isebenze kuphela amandla esincishisiwe. Umlawuli isinyathelo-up kuyodingeka ukuqoqa ngokwakho.
