Transformer ni igikoresho gikoresha ihame rya elegitoroniki mu guhindura voltage ya AC. Ibice byacyo by'ingenzi birimo coil y'ibanze, coil y'inyongera n'inkingi y'icyuma.
Mu mwuga w’ikoranabuhanga, ukunze kubona igicucu cya transformateur, ikoreshwa cyane mu gutanga amashanyarazi nk'amashanyarazi yo guhindura amashanyarazi, isolation.
Muri make, igipimo cy'amashanyarazi cya coils z'ibanze n'iz'inyongera kingana n'igipimo cy'izunguruka cya coils z'ibanze n'iz'inyongera. Kubwibyo, niba ushaka gusohora voltages zitandukanye, ushobora guhindura igipimo cy'izunguruka cya coils.
Dukurikije imikorere itandukanye ya transformers, muri rusange zishobora kugabanywamo transformers zifite frequency nke na transformers zifite frequency nyinshi. Urugero, mu buzima bwa buri munsi, frequency y'ingufu zisimburana ni 50Hz. Transformers dukora kuri iyi frequency ni transformers zifite frequency nke; frequency y'imikorere ya transformer ifite frequency nyinshi ishobora kugera kuri kHz icumi kugeza kuri kHz amagana.
Ingano ya transformer ifite frequency nyinshi ni nto cyane ugereranyije n'iya transformer ifite frequency nke ifite imbaraga zimwe zo gusohora
Transformateur ni igice kinini cyane mu ruziga rw'amashanyarazi. Niba ushaka ko ingano y'amashanyarazi iba nto mu gihe ugenzura ko ingufu zisohoka zihagije, ugomba gukoresha transformateur ifite frequency nyinshi. Kubwibyo, transformateur zifite frequency nyinshi zikoreshwa mu guhinduranya ingufu.
Ihame ry'imikorere ya transformer ifite frequency nyinshi na transformer ifite frequency nke ni rimwe, byombi bishingiye ku ihame rya induction ya electromagnetic. Ariko, ku bijyanye n'ibikoresho, "cores" zabo zikoresha ibikoresho bitandukanye.
Umutima w'icyuma wa transformer ifite frequency nke muri rusange ugizwe n'impapuro nyinshi za silikoni, mu gihe umutima w'icyuma wa transformer ifite frequency nyinshi ugizwe n'ibikoresho bya rukuruzi bifite frequency nyinshi (nka ferrite). (Kubera iyo mpamvu, umutima w'icyuma wa transformer ifite frequency nyinshi muri rusange witwa core ya rukuruzi)
Mu muyoboro w'amashanyarazi uhamye wa DC, transformer ifite frequency nke yohereza ikimenyetso cy'umuraba wa sine.
Mu guhinduranya amashanyarazi, transformer ifite frequency yo hejuru yohereza ikimenyetso cy'umuraba wa kare w'ingufu zo mu bwoko bwa pulse.
Ku ngufu zigenwe, igipimo kiri hagati y’imbaraga zisohoka n’imbaraga zinjira za transformateur cyitwa ubushobozi bwa transformateur. Iyo imbaraga zisohoka za transformateur zingana n’imbaraga zinjira, ubushobozi ni 100%. Mu by’ukuri, transformateur nk’iyo ntibaho, kuko igihombo cy’umuringa n’igihombo cy’icyuma bibaho, transformateur izagira igihombo runaka.
Igihombo cy'umuringa ni iki?
Kubera ko coil ya transformateur ifite ubushobozi bwo guhangana n'ingufu runaka, iyo umuriro unyuze muri coil, igice cy'ingufu kizahinduka ubushyuhe. Kubera ko coil ya transformateur ipfundikiwe n'insinga y'umuringa, iki gihombo nanone cyitwa igihombo cy'umuringa.
Gutakaza icyuma ni iki?
Gutakaza icyuma cya transformer ahanini birimo ibintu bibiri: gutakaza hysteresis no gutakaza umuyoboro wa eddy; Gutakaza hysteresis bivuga ko iyo umuyoboro usimburana unyuze muri coil, imirongo y'imbaraga za rukuruzi izakorwa kugira ngo inyure mu gice cy'icyuma, kandi molekile ziri mu gice cy'icyuma zizahura kugira ngo zikore ubushyuhe, bityo zigakoresha igice cy'ingufu z'amashanyarazi; Kubera ko umurongo w'imbaraga za rukuruzi unyura mu gice cy'icyuma, igice cy'icyuma nacyo kizatanga umuyoboro watewe. Kubera ko umuyoboro urimo kuzenguruka, witwa kandi umuyoboro wa eddy, kandi gutakaza umuyoboro wa eddy nabyo bizakoresha ingufu zimwe z'amashanyarazi.
