Isinyathelo-up transformer owaziwa ...

endaweni ngayine inezidingo zayo ubuchwepheshe kudivayisi yayo yisakhiwo sodumo, ubuka ukuthi ubani ngempela ukuthi yini, kuphi, kanjani. Span - ulwandle, yezikebhe, imikhumbi. Propeller - zezindiza, izindiza, isondo - ibhayisikili, imoto, njll Futhi thina azibonisi njalo iqiniso lokuthi lapho lezi amadivaysi manje elula futhi ecacile abanjalo babehamba esilandelayo, ngezinye izikhathi isinyathelo esinzima ukuthuthukiswa legatsha lonke engineering noma ifayela eliwumthombo.

umlando okunjalo futhi umeleli owaziwa Ihluzo Elingafaki Ukuqoka - transformer. Ngo kakade ezikude 1831 Faraday langena umlando kokutholakala lokungeniswa kagesi - eyisisekelo isimiso yokusebenza transformer. Kuphela emva kweminyaka 45, usosayensi Russian PN Yablochkov unikwe igunya lokwenza kokusungulwa transformer. Laba bobabili ohlobo zitholakala core evulekile, waqinisekisa ukuthi kungenzeka ukuba uguqule, okungukuthi, ukuguqula, shintsha imisinga kanye voltages. Zona lokuqala lalakhiwa transformer. Transformers Modern babe izilinganiso izakhiwo samaphansi eziningana umkhiqizo amancane lingaphansi kuka 1 cm, futhi umkhiqizo wabo - iyona legatsha eziholayo imboni kagesi.

Le nqubo isetshenziswa isibalo esikhulu sezithunjwa transformers izinjongo ezihlukahlukene futhi ngayine inezidingo zayo igama layo ethize. Ngokwesibonelo, ukusetshenziswa kabanzi kagesi ine isinyathelo-up voltage transformer, okuyinto i-voltage okukhiphayo of kilovolts eziningana awumthombo voltage ka 220 V

Ngakho, transformer - kuyini? Inchazelo zakudala simi ngale ndlela: transformer - kuyinto umshini kagesi oguqula okokufaka umthombo wamandla zamanje ku secondary emazombezombe nge voltage ezahlukene. Transformer usebenza ne-AC voltage, ngoba umphumela lokungeniswa ubonakala kuphela lapho kagesi ensimini. Ukudlulisela (ukuguqulwa) energy sidlula ukuguquka amandla kagesi kuleli Windings emkhakheni wokuqala kazibuthe, futhi eminye - inguquko emuva energy kagesi zamanje, kodwa yesibili emazombezombe. Uma yesibili emazombezombe ngenani ematfuba idlula eyinhloko, siba transformer isinyathelo-up, futhi uma ukuxhuma Windings okunalokho transformer kuyoba "okuphambene" - ukunciphisa.

Ake sithi kudingeka egalaji, elithatha 36V inethiwekhi kagesi, ukuxhuma imithwalo kagesi, ezifana ukushaja iyunithi akkamuljatora inikwa amandla yi-220 - isimo esiveza lokhu ukuze sisebenzise transformer isinyathelo-up. Isixazululo sale nkinga, sicabanga izinyathelo ezingokoqobo.

1. Amandla ishaja kuzothatha kusukela ipasipoti - cishe kuzoba into efana Watts 100. Eqaphela ukuthi ngaso sonke isikhathi kudingeka ube nesilinganiso zekusasa futhi uma sicabangela kahle ikusasa transformer ka mayelana 0.9, amandla ayetholakala esiyinhloko 150W emazombezombe.

2. Khetha ijoka. Kuyinto elula ukulawula O emise core kazibuthe (TV ubudala). Singasebenzisa noma iyiphi, esigabeni kabani engu- lincane wabikezela kusukela ubuhlobo: P 1 = S * S / 1,44, lapho P1 futhi S - amandla transformer Watts kanye core cross-section ku isikwele cm. Ukubala inika ukubaluleka S = 10,2 cm2.

3. Isinyathelo esilandelayo ebaluleke kakhulu ngesikhathi "ukwakhiwa" we transformer - kunqunywa inani kuvula 1B: N = 50 / S = 50 / 10.2 = 4.9 ematfuba / e. Manje-ke kulula ukubala inani badedelane (noma, njengoba "emazombezombe Imininingwane"), Windings aphansi nezamabanga aphakeme: w1 = 36 * N = 176 ematfuba kanye W2 = 220 * 5 = 1078 ematfuba.

4. Chaza imisinga emazombezombe. Kusuka kithina ukuthi amandla ngamunye Windings ka mayelana 150 Watts. Kulokhu, ezisebenza Windings wamanje: J1 = 150/36 = 4,2A futhi J2 = 150/220 = 0,7A.

5. Manje unazo zonke idatha ukucacisa diameters we izintambo we Windings. Sizokwenza njalo, ngoba udaba eyinhloko ikhoyili D1 = 0.8 * √J1 = 0.8 * 2,05 = 1,64mm sq. ;

efanayo ukuze yesibili D2 emazombezombe = 0.8 * √J2 = 0,8 * 0,84 = 0,67 mm sikwele.

Han ohlobo khetha diameters ivela ejwayelekile.

Konke! Ukubala sesidlulile, kodwa angakhiqiza isinyathelo-up transformer ngezandla zabo? Njengoba Bathi - akukho lula, uma kudingeka kabi. Isidingo real - kuba main ukushayela force diy, ukuze eminye izibambo, izibambo.

6. Qiniseka isidumbu amabili akhethiwe wesifunda kazibuthe.

ukustaka 7. ozimele obukhulu is nilimaza ngesigamu oyinhloko emazombezombe futhi ukuhlukanisa ke glass- noma varnished.

8. Ngokulandelayo, zabekwa phezu kwelinye ipulangwe ngesigamu sesibili emazombezombe futhi ngizikhokhele varnished.

9. Inhlangano circuit kazibuthe, coupler ijoka izingxenye - inkinga akunzima kakhulu. Ngo ukuhlangana magnetic core neengcezu efiselekayo ukunamathisela iyiphi Ukwakheka usebenzisa ferroporoshka - lokhu ngeke sizamukele "kuyachwaza" zedivayisi ngesikhatsi kokuhlinzwa.

Nazo-ke! ezenziwe ekhaya lethu, akufanele sicabange sizosebenza isikhathi eside nenjabulo. Obani abangathanda singabaze!
