Zimakupiza liwiro. Triac ulamuliro zimakupiza liwiro

Ndipotu, zimakupiza ulamuliro liwiro wakhala kusintha voteji kuti umagwiritsidwa ntchito chipangizo. Ngati ife kulankhula za injini, chipangizo zatchulidwazi ndi udindo kusintha kwa windings. Pamene pafupipafupi izi panopa akhoza kwanthawi kwambiri.

Ndi kuyamika owongolera mafani magetsi akhoza kutumikira mwini kwa zaka zambiri. Izi zimachitika chifukwa yafupika avale zigawo zikuluzikulu zofunika makina. Komanso, n'zotheka kuchepetsa mowa magetsi. Poyankha, fani zambiri phokoso kuthamanga pa liwiro apamwamba.

zimakupiza Thyristor

Thyristor zimakupiza liwiro (chiwembu pansipa) angathe kuikidwa chokhazikika pa zida umodzi gawo. Kuchokera mbali amatha kusiyanitsa dongosolo odalirika chitetezo. Ndiyamika kusaberekalo liwiro zimakupiza chindiletsa kutenthedwa zigawo zikuluzikulu yovuta. The patsogolo chifukwa akhoza lizilamuliridwa ndi kusinthasintha mphamvu panopa.

Maukonde ndi voteji a 220 akutumikira monga magetsi chipangizo B. The pafupipafupi pafupifupi kuzungulira 55 Hz. The pazipita chovomerezeka voteji kupatuka pa 15%. zitsanzo zambiri za anthu opha thyristor zili ndi masensa wapadera. Zipangizo ambiri amaona kuti olembedwa kuti "RTS". Iwo akhoza kugwiritsidwa ntchito pa kutentha madigiri kwa -50 kuti +50. The unsembe wa ulamuliro zimakupiza liwiro wokongola yosavuta. Pankhaniyi chizindikiro kasinthasintha liwiro anapereka.

Features wa anthu opha pafupipafupi

Childs, pafupipafupi Mtsogoleri zimakupiza liwiro akhoza kulimbana ndi voltages kwambiri. Pamene liwiro rotational limasintha mwa kusintha pano. Nthawi zambiri, mtundu angapezeke pa zosiyanasiyana machitidwe mpweya. Zina owongolera pafupipafupi abwino zipangizo ntchito mpweya mpweya wabwino. Ambiri, zipangizo pamwamba ndi wokongola yosavuta.

Kaperekedwe owongolera pafupipafupi

Iwo kudya maukonde ndi voteji a 220 V. The mphamvu linanena bungwe la zimakupiza nthawi yomweyo sayenera upambana 500 Watts. Zolemba malire kukana yang'anira pafupifupi wofanana ohms 300, ndipo dongosolo ulamuliro chizindikiro akhoza anazindikira kuti 10 V. yomweyo amadya mphamvu Mtsogoleri wagawo 3 B.

Standard chipangizo akonzedwa tichipeza chingwe ndi osachiritsika mtundu chipika wononga. Mafyuzi mu chipangizo zilipo ndi mphamvu panopa osachepera 3 Digiri ya chitetezo zitsanzo zambiri kalasi "IP21". Ntchito pafupipafupi Mtsogoleri zimakupiza liwiro mungathe pa kutentha madigiri kwa -10 kuti +30.

opha thiransifoma zimakupiza

Thiransifoma Mtsogoleri 12b zimakupiza liwiro ntchito yokhayo yotumikira mkulu-mphamvu osakwatiwa-gawo kapena atatu gawo Motors. Mwachindunji kuyan'anila kusintha anachita unsembe stepwise. Pankhaniyi, n'zotheka kukhazikitsa mgwirizano basi. masensa Kutentha amene anaika mu zitsanzo zambiri.

Komanso, inu mukhoza kusankha thiransifoma akulamulira mafani ndi zizindikiro chinyezi. Komabe, mphamvu zawo zikhoza kusintha ntchito powerengetsera. zipangizozi ndi wokwera ntchito zomangira. chipangizo ndi cholinga chowapatsa clamps wapadera kuumitsa pawiri. Ngati kukhudzana koyambirira malo zilipo. zingwe mphamvu monga muyezo m'gulu.

Fundo thiransifoma yang'anira waima pa ohms 400. Pamene chizindikiro kulamulira amaona kuti 4 V. Komanso tisaiwale mkulu katundu kulandirana linanena bungwe. Mphamvu mowa chipangizo zimasiyanasiyana avareji pafupifupi 12 V. Ambiri, zipangizozi ali ndi bulky poyerekeza ndi mafani pafupipafupi owongolera ndi okwera mtengo kwambiri.

Mitundu Triac Mtsogoleri

Triac ulamuliro zimakupiza liwiro zida ndi zovuta kwambiri mitundu yonse tatchulazi. Amagwiritsidwa ntchito kuchepetsa zipangizo angapo nthawi imodzi. Pankhaniyi injini awa angathe kuikidwa zonse ndi alternating panopa. Mwachindunji kusintha liwiro amapezeka kwambiri bwino.

M'pofunikanso kukumbukira kuti voteji osiyanasiyana n'chachikulu kwambiri. Special mwatsatanetsatane kuima-gawo yang'anira chitsanzo. Kuchepetsa voliyumu ya ntchito chipangizo mu limagwirira ali ndi wapadera kuwongola capacitor. Khazikitsa triac Mtsogoleri angakhale osiyana. Ambiri amaona kuti chamadzi phiri, koma opanga ambiri amatha kupereka iyambitsa zipangizo kunja fixation.

Mfundo ntchito triac Mtsogoleri

Processing deta zonse wakhala kwathunthu microprocessor unit. Nawonso, adzakhala popereka chizindikiro triac ulamuliro zimakupiza liwiro ali kachipangizo a. Izo zikugwirizana kudzera ndi polowera pa za gulu mbali. Komanso, sensa ndi opaleshoni kuti kuwunika kutentha chipangizo. Mu izi kukana chipika mosalekeza chosinthika.

Kuthetseratu kuwasokoneza kuti kuonekera pa opaleshoni, pali fyuluta yadigito. Ndiponso kuzima nacho zimachitika anagona mu dongosolo. Resistor zimakupiza liwiro Mtsogoleri ndi udindo panopa asinthe. Chifukwa, nyamuka lakuthwa mu kachipangizo kutentha akukamba mbendera kuchepetsa voteji. Komanso kwambiri zimadalira mwachindunji zoikamo triac Mtsogoleri. Choncho, mapulogalamu, mungathe kusintha mtengo zofunika.

Khazikitsa triac Mtsogoleri

Kukhazikitsa zimakupiza liwiro Mtsogoleri 220 ayenera kwathunthu kusagwirizana maukonde. Komanso, m'pofunika kuchotsa gulu zofunika, limene lili moyang'anizana ndi chipangizo. Only ndiye inu mukhoza kusagwirizana unit chivundikirocho. Sitepe yotsatira ndi kukhazikitsa kachipangizo kutentha kwa polowera lapansi. Mphamvu machitidwe okwanira ayenera kukhala bwino ndi dera la unit.

kugwirizana ndi galimoto zimakupiza imagwiridwa mwa amalimata ochititsa Shackleton mtundu. Ndiye mpweya anazimitsa capacitor umene uli pafupi ndi kachipangizo kutentha. Nkofunika kuti aletse chipangizo mains zitsulo. Pakuti kugwirizana bwino pasakhale kudetsedwa. Apo ayi mbendera sangafikire microprocessor unit. Kuyeretsa cholumikizira ndi qualitatively, akatswiri ntchito njira kuchotsa okusayidi mkuwa.

Pambuyo kukonza pamwamba chivundikiro mosadziteteza gawo afewetsedwa phala zabwino matenthedwe madutsidwe. Monga ulamuliro, ntchito chida yekha pamaziko a sanali kuyanika. mbale mbali ndi wokwera pa yang'anira simistrovogo latches. Kuchokera pamwamba iwo amagwiritsidwa glued kuti kutchinjiriza ndi. M'menemo m'lifupi Mzere sayenera zosakwana 10 mm. Ndiye 220 zimakupiza ulamuliro liwiro akhoza pa khumudwitsidwa ndi. Nkofunika kulabadira Kulumikizana ndi achepetsa pamene chipangizo chamagetsi cha yatsekedwa. Chinthu chomaliza ku unsembe ndi kugwirizanitsa magetsi. Ataona ndandanda cholumikizira kuti ampase mphamvu kuchita mayesedwe kulolerana.

Zitsanzo kwa mafani ndi Motors asynchronous

Chinthu chapadera zitsanzo zambiri ndi ulamuliro stepless liwiro. fani ayenera panopa mwadzina la osapitirira 6 A, ndi pafupipafupi pafupifupi - m'chigawo cha 45 Hz. The magetsi Mtsogoleri ndi zopezera 230 V Digiri ya chitetezo apereka kalasi "IP 54". Pulogalamu dongosolo ndi Mtsogoleri wapadera.

Chifukwa owongolera pamwamba, injini chiyambi-mmwamba ikuchitika ndithu bwino. Kutsinde izo imazungulira pa pafupipafupi nthawi zonse. Current chitetezo galimoto waikidwa mu zitsanzo zambiri. Liwiro osachepera kukhazikitsa Mtsogoleri ngati nkotheka.

Mbali imeneyi ndi khalidwe la opha ndi potentiometers kalasi VM ndi VX. Yambitsaninso liwiro Mtsogoleri gulu amatsatila, ndipo inu mukhoza kuwona ntchito yake pa diode zimatulutsa kuwala emitting. Kuti ziziyenda bwino mu voteji pa galimoto kumulowetsa ali microcontroller. Kuchotsa gawo zosiyidwa akhoza kukwaniritsa Mwachangu mkulu mphamvu.

owongolera chotenthetsera

Yang'anira chotenthetsera zimakupiza liwiro angathe kuchepetsa phokoso ku ntchito galimoto ndi. Pa nthawi yomweyo limatipatsa yabwino ulamuliro kunja. Chifukwa cha zimenezi, mungathe kuchepetsa kumwa magetsi.

Komanso, avale chigawo ali ndithu yafupika ndi kusintha malire pafupipafupi. Udindo mu dongosolo zimachitika m'lifupi modulator. Zikugwira ntchito yang'anira panopa kuzungulira 0,7 A. The pazipita mphamvu linanena bungwe ndi kuzungulira 550 Watts. Lowetsani impedance owongolera a kalasi anakhalabe pa kuzungulira 200 ohms. Pamene chizindikiro kulamulira amaona 8 V. chingwe Nthawi zambiri m'gulu ntchito isagwe.

Katundu pa mzere zotuluka pafupifupi analola 3 A. Nawonso mowa chipangizo mphamvu mu osiyanasiyana kuchokera 4 mpaka 8 V. The mafyuzi mu owongolera kachitidwe mpweya anaika lama fuyusi kalasi, angathe kuchepetsa panopa loyenda pa 5 A. The mlingo wa chitetezo pa ali kalasi "IP21". Mayina lonse zitsanzo za kachitidwe mpweya yekha kunja - kudzera mwa zomangira. Ambiri, ali yaying'ono kwambiri ndi kulemera pang'ono kwambiri.
