Imikorere ya optocoupler relay mu gutanga amashanyarazi

Akamaro k'ingenzi ka optocoupler mu ruziga rw'amashanyarazi ni ugukora ihererekanya ry'amashanyarazi mu gihe cyo guhinduranya amashanyarazi no kwirinda kubangamirana. Akamaro ka disconnector ni akagaragara cyane muri ruziga.

Ikimenyetso kigenda mu cyerekezo kimwe. Injira n'isohoka byashyizwe ukwabyo burundu mu buryo bw'amashanyarazi. Ikimenyetso cyo gusohora nta ngaruka bigira ku byinjira. Ubushobozi bukomeye bwo kurwanya ikibazo, imikorere ihamye, nta gukoranaho, kumara igihe kirekire no gukora neza cyane. Optocoupler ni igikoresho gishya cyakozwe mu myaka ya 1970. Kuri ubu, gikoreshwa cyane mu gukingira amashanyarazi, guhindura urwego, guhuza hagati y'ibice, circuit yo gutwara, switching circuit, chopper, multivibrator, signal isolation, interstage isolation, pulse amplification circuit, digital instrument, long-distance signal transmission, pulse amplifier, solid-state device, state relay (SSR), igikoresho, itumanaho n'interface ya microcomputer. Mu buryo bwa monolithic switching power supply, linear optocoupler ikoreshwa mu gukora optocoupler feedback circuit, kandi duty cycle ihinduka binyuze mu guhindura control terminal current kugira ngo hagerwe ku ntego yo kugenzura neza voltage.

Akamaro k'ingenzi ka optocoupler mu guhinduranya amashanyarazi ni ugutandukanya, gutanga ikimenyetso cyo gusubiza no guhinduranya. Ingufu za optocoupler mu gice cy'amashanyarazi gihinduranya zitangwa na voltage ya kabiri ya transformer ifite frequency nyinshi. Iyo voltage isohoka iri hasi ugereranyije na zener voltage, fungura optocoupler y'ikimenyetso hanyuma wongere cycle y'akazi kugira ngo wongere voltage isohoka. Ahubwo, kuzimya optocoupler bizagabanya cycle y'akazi kandi bigabanye voltage isohoka. Iyo umutwaro wa kabiri wa transformer ifite frequency nyinshi urenze urugero cyangwa circuit ya switch ikananirwa, nta power ya optocoupler ibaho, kandi optocoupler igenzura circuit ya switch kugira ngo idahindagurika, kugira ngo ikingire umuyoboro wa switch gutwikwa. Optocoupler ikoreshwa cyane na TL431. Ibikoresho bibiri bifatwa mu buryo bukurikiranye kuri terminal ya 431r kugira ngo bigereranywe na comparator y'imbere. Hanyuma, dukurikije ikimenyetso cyo kugereranya, imbaraga zo kurwanya ubutaka za 431k (aho anode ihujwe na optocoupler) ziragenzurwa, hanyuma urumuri rwa diode itanga urumuri muri optocoupler rukagenzurwa. (hari diode zitanga urumuri ku ruhande rumwe rwa optocoupler na phototransistors ku rundi ruhande) imbaraga z'urumuri zinyuramo. Genzura imbaraga zo kurwanya ku mpera ya CE ya transistor ku rundi ruhande, hindura chip ya LED power drive, hanyuma uhindure mu buryo bwikora imikorere y'ikimenyetso cy'umusaruro kugira ngo ugere ku ntego yo gushimangira voltage.

Iyo ubushyuhe bw'ikirere buhindutse cyane, ubushyuhe bw'ikintu cyongera imbaraga buba bunini, ibyo bikaba bitagomba gukorwa na optocoupler. Optocoupler ni igice cy'ingenzi cyane mu guhinduranya amashanyarazi.
