How kutarisa transistor

Munyika yazvino haagoni kuita pasina transistors. Vakauya zvakasiyana zvemagetsi, vanogona kuwanikwa phones, maredhiyo, makombiyuta uye mota. Dzimwe nguva pane kudikanwa ongororo maitiro avo, uye ipapo zvinobatsira kuziva sei kuona transistor uye kuti ichi zvinoda. The akurukurwa munyaya inosimbisa nyaya.

Transistors uye mhando

mudziyo Iri wemagetsi, iro rinoshandiswa kuti kuwedzera electroschemes yepakutanga chiratidzo. Wakaitwa kubva semiconductor nezvinhu. Kune 2 marudzi ose transistors: munda uye dambudziko, hadzina kudzorwa voltage uye ano. Mukuwedzera, vanogona kuva mutete uye simba, pasi uye yakakwirira maitikiro. Vakasiyana kukura uye ezvivako.

Kazhinji kana achitaura dambudziko transistors kureva mhando dzavo, vari akagadzirwa negermanium kana nesilicon. Dzinonzi nedambudziko nokuti vashande maerekitironi (mutariri vatakuri) uye maburi. Imwe nzvimbo transistor riri pamahombekombe, yainzi emitter, zvenguva - nechigadziko, uye mumwe, uyewo riri pamupendero - nemuteresi. Sezvo electrode 3 pave PN Kuchinja 2: muteresi anoda pakati muteresi uye nechigadziko, uye emitter iyo zvakabatana pakati emitter uye chawo. The transistor anogona kuva "pamusoro" nehurumende uye "kubvisa", uye kuchinja pakati pavo rinoitwa pachishandiswa zviratidzo zvemagetsi.

Huru chinangwa transistors - rudzi, amplification uye kutendeuka magetsi oscillations. Asi, sezvo paine zvekushandisa mudziyo, kuti transistor angatadza. Unofanira kuziva kuti kutarisa transistor kuti mugumisiro kuti musoro. Nokuti chinangwa ichi multimeters.

Vachiongorora transistor tester

Multimeter (aka Tester) - iri mudziyo unokosha yaisanganisa, naro zvidzidzo magetsi basa. Chine anoverengeka mabasa: sezvo kushoma rinobatanidza ammeter, voltmeter, ohmmeter. Kune vose analoginen uye digitaalinen namano, chiedza, inotakurika uye mira, izvo rinobatanidza zvakawanda mikana.

Meter - zano kuti anoudza sei kuona transistor uye kujekesa. Tester anobvumira wakaita raundi uine yakaderera nemishonga kuyera dunhu, aramu ichirira, inzwi kana chiedza.

Tisati taongorora muitiro, sei kuti kutarisa transistor tester, zvakakosha kuziva kuti maturusi ava akakamurwa 2 mhando maererano urongwa akaturikidzana nedzimwe conductivity. Saka pane semiconductors pamwe zvemagetsi conductivity (pnp), uye peji-mhando semiconductors (p-).

Kuedza kurwisa munhu rakananga yezwi nechigadziko kubatanidza "kubvisa" kuti mita uye emitter uye nomuteresi zvinozoita batanidza "ndinoiitawo". kushandura nzvimbo "kubvisa" uye "ndinoiitawo" zvisizvo nemishonga kuyerwa. Kuti ayere kurwisa kuchinja pnp kudzokorora chete nzira, asi preliminarily kuchinja polarity. Panguva yezwi cheki kubva muzasi kusvika emitter uye nomuteresi vanofanira prozvanivatsya chete 1 divi.

Sezvo multimeter kutarisa transistor kunogona, asi haina kupa vimbiso mhedziso serviceability ari mudziyo, nokuti chokwadi chikuru chinofanira kuitisa ayo yokudzokorora mu chinoshingaira nzira. Panyaya iyi, zvichabuda zvikuru rakavimbika.

Asi: sei kuongorora zviri transistor uye kuvimba migumisiro? In nedambudziko mano zvivanakire, unogona kuwana nokuti diode dzomuzana nomumwe kuchinja ayo, pashure pokuongorora serviceability kwavo. Pane transistors simba kuti zvinosanganisira pakati emitter uye nomuteresi pamusoro damper muviri diode, uye pakati nechigadziko uye emitter - rwokudzivirira resistor. Kana mita chero polarity transistor ichi chichava nemishonga inobva matatu kusvika makumi mashanu ohms, uye prozvanivatsya pakati emitter uye nomuteresi zvichadaro somunhu diode. Izvi zvinopupurira serviceability zvikamu.
