A anozivikanwa danho-up transformer ...

Nzvimbo imwe neimwe ine michina iconic mudziyo wayo, kutarisa ndiani zvachose kuziva chii, kupi, sei. Maseiri - gungwa, yacht, ngarava. Hwindimiri - avhiyesheni, ndege, vhiri - bhasikoro, motokari, etc. Uye hatidi nguva yokufunga kuti kamwe izvi zvino nyore uye zvakajeka kudaro namano vakanga akatevera, dzimwe nguva danho zvakaoma kukura yose bazi engineering kana zvokuimba mapurani.

Nhoroondo yakadaro uye mumiriri inonyatsozivikanwa pamusoro zvemagetsi okugadzira - transformer. In kare kure 1831 Faraday akapinda nhoroondo kuwanikwa remagetsi induction - inokosha musimboti kushanda ari transformer. Chete pashure pemakore 45, musayendisiti Russian PN Yablochkov akapiwa imwe bvumidzwa nokuda michina yacho transformer. Vaviri Coils dziri pamusoro pakachena paro, akasimbisa mukana kuchinja, kureva, kutendeutsa, yokugadziridza dzenzvimbo uye voltages. Pakutanga yaiumbwa transformer. Modern transformers vane kukura zvivako mapuriro akawanda kune tuduku chigadzirwa idukusa 1 masendimita, uye kugadzirwa kwavo - ndiye aitungamirira bazi magetsi indasitiri.

Nzira inoshandiswa zhinji transformers chinangwa siyana uye mumwe nomumwe ane zita yayo chaiyo. Somuenzaniso, kushandiswa kwakapararira zvemagetsi ane danho-up voltage transformer, iri panzvimbo goho voltage pamusoro kilovolts anoverengeka ndiyo pomugove voltage kuti 220 V.

Saka transformer - chii? The klassiske tsananguro iri sezvinotevera: transformer - ndiyo wemagetsi muchina kuti vatendeuki mazano simba panobva kuitika munzvimbo yechipiri ichitenderera ne akasiyana voltage. The transformer anoshanda pamwe AC voltage, nekuti induction zvazviri inoonekwa chete kana remagetsi munda. Kuchinjwa (kuchinja) simba ichipfuura kutendeuka zvemagetsi simba iri windings pakutanga remagineti, uye zvakare - kuchinja shure kune magetsi ano simba, asi mune yechipiri ichitenderera. Kana yechipiri ichitenderera pamusoro nhamba muchichinjana akapfuudza chikuru, tine danho-up transformer, uye kana imi kubatanidza windings pamusoro kudaro, transformer achava "Zvakasiyana" - rutapudzo.

Ngatitii kuti unofanira mugaraji, rine yemagetsi 36V network, batanidza magetsi mitoro, akadai ndinorova chikwata akkamuljatora dzinofambiswa 220 - chaiwo nyaya kuti kushandisa danho-up transformer. Kugadzirisa Dambudziko iri, isu funga matanho.

1. Simba mundiro achatora kubva pasipoti - Ungangove zvichava chinhu chakafanana 100 watts or. Kuziva kuti nguva dzose unofanira kuva kumucheto yomunguva yemberi uye tichifunga nezveramangwana kunyatsoshanda pamusoro transformer vanenge 0,9, mukuru akagamuchira simba zvikuru ichitenderera 150W.

2. Sarudza joko. Zviri nyore kudzora O-zvakaumbwa rinobva chinoumba (chakare TV). Tinogona kushandisa chinhu, ane chikamu muchinjikwa idukusa akafanotaura kubva ukama: P 1 = S * S / 1,44, apo p1 uye S - transformer simba iri watts or uye chinoumba muchinjikwa chikamu pachivara cm. The kukarukureta rinotipa kukosha S = 10,2 cm2.

3. Danho rakatevera ndiro rinokosha kupfuura panguva "kuvaka" the transformer - kunotemwa nenhamba muchichinjana musi 1b: N = 50 / S = 50 / 10.2 = 4.9 majana / mu. Zvino zviri nyore ngaaverenge nhamba muchichinjana (kana, se "ichitenderera ruzivo"), nesekondari windings: W1 = 36 * N = 176 majana uye W2 = 220 * 5 = 1078 muchichinjana.

4. Dudza ichitenderera dzenzvimbo. Tinopa rumbidzo kuti simba nerimwe windings vanenge 150 watts or. Muchiitiko chino, kushanda ano windings: J1 = 150/36 = 4,2A uye j2 = 150/220 = 0,7A.

5. Zvino iwe ose Data kuona diameters ose tambo yacho windings. Tichaita saizvozvo nekuti chikuru coils D1 = 0,8 * √J1 = 0,8 * 2,05 = 1,64mm ba. ;

saizvozvowo nokuda yechipiri ichitenderera D2 = 0,8 * √J2 = 0,8 * 0,84 = 0,67 mm akaenzana.

Ichitenderera Coils sarudzai diameters achibva pomureza.

Zvose! The kukarukureta yapera, asi zvinogona danho-up transformer nemaoko avo? Sezvo vanoti - hapana nyore, kana zvakaipa zvinodiwa. Kudiwa chaiyo - ndicho chikuru Rinokurudzira DIY, saka kuti mamwe Pazvibato, rinopindura.

6. Ita chitunha maviri pamusoro vakasarudzwa rinobva redunhu.

7. mapuranga gobvu kuisira iri muchikuvadza nehafu chikuru ichitenderera uye achipfigire glass- kana Varnished.

8. Next, ukapisa murwi pamusoro pepuranga rimwe nerimwe hafu yechipiri ichitenderera uyewo yakavafukidza Varnished.

9. paungano rinobva redunhu, coupler joko zvikamu - dambudziko harisi chakaoma chaizvo. In vanoungana kuti rinobva chinoumba sezvikamu chinhu chinodiwa kuti micheto yekapepa katsva aka chero sezvamunoita vachishandisa ferroporoshka - ichi siya "vava kungotaura nezvekudzoka" ari mudziyo panguva oparesheni.

Ndizvozvo! musha-akaita zvedu, hatifaniri kufunga kuti kushanda kwenguva refu uye mufaro. Uye vanoda chokwadi!
