Yakasiyana-siyana yemidziyo yemumba, maindasitirifrequency transformers, pasinei nokuti vanogadzira mhepo yavo pachavo, kana kugadzirisa iyo yakatsva transformer, inobatanidzwa mune chikamu chekuverenga nyore, mabhuku ezvinyorwa pamusoro pemaitiro, kunyange zvazvo akaoma, asi kushandiswa kunoshanda kwekuoma, kwete zvakanyanya nyore.Ichi chinyorwa chinosuma iyo inoshanda transformer kuverenga yeempirical formula.
1. Iron core kusarudzwa
Zvinoenderana nesimba ravo pacharo zvinoda kusarudza iyo chaiyo musimboti ndiyo nhanho yekutanga mukupeta transformer. Kana iyo simbi yesimbi (silicon simbi pepa) kusarudzwa kwakakura zvakanyanya, kuchaita kuti kuwedzera kwekukura kweshanduko, mutengo wepamusoro, asi simbi yesimbi yakanyanya kudiki, ichawedzera kurasikirwa kweshanduko, nepo kugona. kutakura mutoro unova murombo.
Kuti uone ukuru hwesimbi yesimbi, chinhu chekutanga kuverenga iyo chaiyo simba rekushandisa ye transformer yechipiri, iyo yakaenzana ne transformer yechipiri mhepo yemhepo, uwandu hwechigadzirwa chemutoro wezvino. Kana iri full-wave rectifier transformer, inofanira kuverengwa se 1/2 ye transformer secondary voltage. Sekondari mamhepo mashandisirwo emagetsi kujoina transformer pachayo kurasikirwa kwesimba, kureva, iyo transformer yekutanga inooneka simba.
General yechipiri mamhepo simba mu10w pazasi petransformer, kurasikirwa kwayo kwechipiri kushandiswa kwemagetsi kunogona kusvika ku30 ~ 50% yesimba chairo rekushandisa, kushanda kwayo kunongova 50 ~ 70%. Sekondari simba remamhepo mu30 w pazasi kurasikirwa kwe20 ~ 30%, 50 w pasi pekurasikirwa kweanenge 15 ~ 20%, 100 w pazasi kurasikirwa kweanenge 10 ~ 15%, 100 w pamusoro pekurasikirwa kweinenge gumi% pazasi, zviri pamusoro. kurasikirwa paramende ndeye yakajairwa plug mhando transformer. Kana kurongeka kweR-type transformer, c-type transformer uye toroidal transformer inoteverwa, kurasikirwa kweparameter kunoderera.
Zvichienderana nehuwandu hwekutanga simba rekushandura rakaverengerwa pamusoro pepakati rinogona kusarudzwa. Iron core area S = axb (cm2). Sezvakaratidzwa mumufananidzo wakabatanidzwa. Transformer inooneka simba uye hukama pakati pe s neinotevera empirical formula: s = K √ P1
P1 for the transformer primary total clear power, unit: VA (volt-ampere), s inofanira kusarudzwa core cross-sectional area, K is a coefficient, nehukuru hwe transformer Pl yakasiyana sarudzo yemhando dzakasiyana. Panguva imwecheteyo, uchifunga nezve silicon simbi pepa pakati pependi inodzivirira, mhedzisiro yegeji, K uye P1 hukama ndeiyi:
P1 K kukosha
10VA 2～2.2
50VA pazasi 2 ~ 1.5
lOOVA pazasi 1.5 ~ 1.4
2. Kuverengera kwekutendeuka kwevolt
Mushure mekusarudza iyo core s. Zvadaro sarudza nhamba yekutendeuka pa volt, kuitira kuti mhepo ishandure ine inonzwisisika excitation ikozvino. Inowanzo shandiswa empirical formula: N = (40 ~ 55)/S, N ndiyo nhamba yekutendeuka pavolti.
Maererano nehutano hwakasiyana hwesilicon steel sheet kusarudzwa coefficient 40 ~ 55. yakawedzera yepamusoro-silicon simbi, neziso rekucherechedza pamusoro pezviyero zvekristallilization. Uye yakanyanyisa brittle, chete 1 kusvika 2 nguva inotyoka, yakatyoka pane isina kuenzana, iyo coefficient inotorwa se 40. Kana iyo silicon simbi pepa pepamusoro yakachena, kukotama 4 kusvika 5 nguva kuchiri kusiri nyore kutyora, chikamu cheiyo yakatsvinda. mutsara wakatwasuka, iyo coefficient inotorwa seanopfuura makumi mashanu.
Tsvaga huwandu hwekutendeuka pavolti imwe yakapetwa ne 220V inova ndiyo yekutanga kutendeuka, yakapetwa nenhamba yemagetsi echipiri anodiwa inova yechipiri matenderedzwa ekutenderera. Nemhaka yokuti waya ine kushorwa, ikozvino kuyerera kuburikidza nekudonha kwemagetsi, kutendeuka kwechipiri kunofanira kuwedzerwa ne5 ~ lO% (maererano nemutoro wezvino kusarudzwa, ikozvino inogona kuwedzerwa nechikamu chikuru).
3. Kusarudzwa kwetambo dhayamita
Zvinoenderana nehukuru hweiyo inotenderera mutoro ikozvino, sarudza akasiyana madhayamita e enameled waya. Iyo inotevera empirical formula inogona kushandiswa kuziva:
d=O.8√I.
Chikamu: l – A. d (waya dhayamita) – mm.
4. Mhepo Nzira uye Dziviriro
Saka, mazuva ano, simba rekudzivirira re enameled wire rakanyanya kuvandudzwa. Formadiki emagetsi emagetsikutenderedza 50W, isu tinowanzoenda nerazvo-retardant epurasitiki skeleton uye kurongedza mahwindi. Ingoita chokwadi chekushandisa yakakwirira-yakasimba enameled waya, uye kana iwe uchiimisa kumusoro, chengeta zvese zvakamisikidzwa mutsara ne layer-hapana hombe diagonal spans inobvumidzwa! Izvi zvinobatsira kudzivirira kuwedzera musiyano wevoltage pakati pewaya. Kune ma transformer anopfuura 50W, sezvo paine mashoma ekutendeuka pavolt, musiyano wevoltage pakati pewaya unokwira. Zvakanakisa kuisa bepa rekudzivirira (senge 0.05mm gobvu tambo bepa kana kraft bepa) kune yega yega yega paunenge uchiipepeta.
Iwe zvechokwadi unoda kudzivirira chero maturu epamusoro kubva pakutsvedza mune akaderera! Iyo insulation pakati pe windings inofanira kuenderana nehuwandu hwemagetsi auri kubata nawo. Pakati pematanho ekutanga, tarisa angangoita mana akaturikidzana e0.1mm cable bepa - svetuka uchishandisa self-adhesive tepi pano! Kana transformer yako diki ine mapoka anopfuura maviri echipiri mamhepo akaturikidzana, ita shuwa yekuwedzera maviri akaturikidzana etambo yekuvharisa bepa pakati peboka rega futi. Uye kana iyi transformer ichipinda muodhiyo kana audiovisual giya? Usakanganwa kusanganisira imwe electrostatic shielding padding mune iwo akawanda-layer setups. Mushure mekunge maita zvese izvo zvinhu zvinomonereka, teerera kana uchiisa silicon simbi mashiti-anofanirwa kukwana zvakakwana kuti urege kuwana ruzha rwemagetsi ruchikanganisa zvinhu.
Angave ari maviri E-shaped kana EI-shaped sheets, anofanirwa kurongedzerwa pamwe chete pasina mapundu; kuvayambuka kunogona kubatsirawo! Paunenge uchiisa muzvidimbu zvishoma zvekupedzisira (zvinenge zvina kana zvishanu), zviite kubva pakati kuti urege kukuvadza chero masumbu e wiring munzira. Ipapo ngatiiomesa toinyika mupende pashure! Kune ma transformer ari pasi pe50W, unogona kushandisa endothermic drying nzira: pfupi-circuit ese echipiri windings kutanga uye wozobatanidza girobhu remwenje (60 ~ 100W / 220V) munhevedzano ine mains simba kuitira kuti inodziya yega yega. Iyo yakakura girobhu, iyo yakakwirira yekushisa, asi munzvimbo yakavharwa, kuitira kuti kutonhora kuri pasi pe80 degrees kwakachengeteka.
