Turabizi ko itumanaho ryitumanaho rigomba kuba ubugome kurenza Mosfet rusange, umutwaro wa relay ni munini kuruta Mosfet.

Ubusanzwe DC itwara moteri ya DC, DC ya DC hamwe na DC solenoid valve, izi modoka zipakurura ibintu zifunze, amagana cyangwa ibihumbi n’ibihumbi bya volt yingufu zinyuma zatewe no kwiyongera bizahuza ubuzima kugirango bigabanye cyangwa byangiritse rwose.Nibyo, niba amashanyarazi ari mato, nkigihe hafi ya 1a, ingufu za electromotive zinyuma zitera gusohoka kwa arc bizatera kwanduza umwanda wa okiside yicyuma, ibyo bikaba byananiranye kunanirwa, kurwanya kwihuza biba binini.

Hano twavuga, kwerekanwa buri gihe birananirana, dukora uburinzi, cyane cyane dushaka kongera igihe cyo gukoresha igihe cyo kwerekanwa, kuko imibonano ihora ijya gushira karubone, gusaza, ubuso bwayo nkibisanzwe bifite isuku.Kurwanya guhura biziyongera byihuse mugihe ubuzima bwa relay buri hafi kurangira.

Muri rusange munsi yubushyuhe busanzwe nigitutu, urufunguzo rwumuyaga dielectric breakdown voltage ni 200 ~ 300V.intego yacu rero muri rusange nukugenzura voltage iri munsi ya 200V cyangwa voltage nto.

Diode isanzwe irashobora kwagura cyane igihe cyo guta, diode isanzwe hamwe na zener diode ikurikirana kandi ntabwo bigira ingaruka zikomeye kumwanya winyuma.Niba ari umutwaro wivangura.Mugihe itumanaho ritandukanye, igihe kinini cyo guhindura igihe kirekire arcing igihe, kandi kizagabanya ubuzima bwa serivisi bwitumanaho.Kurugero, relay ihujwe na diode kuri coil bisaba igihe 9.8m cyo kurekura imibonano.Diode ya zener hamwe na diode ntoya ya signal hamwe, irashobora kugabanywa kugeza kuri 1.9m.Igiceri ntabwo gihujwe na diode ihinduranya igihe 1.5m.

Nubwo umutwaro wa inductive utoroshye gukemura kuruta umutwaro urwanya, gukoresha uburinzi bwiza bizatuma imikorere iba myiza.

Hariho inzira ebyiri zo kuba mbi cyane, ntukoreshe.

Munsi yumutwaro wa DC, guhinduranya inshuro nyinshi bishobora gutera ruswa idasanzwe (spark spark).

Iyo urwego rwo hejuru rugenzura DC solenoid valve cyangwa clutch, imibonano irashobora kubaho ubururu-icyatsi kibisi.Impamvu zibi bintu ni igihe zakozwe na EDM (gusohora amashanyarazi ya arc), azote na ogisijeni mu kirere mubitekerezo byatanzwe.

Ikintu cyo kohereza ibintu

Iyo ibikoresho bihuye, inzibacyuho ibaho mugihe igice cyo guhuza cyashonge cyangwa cyangiritse.Hamwe no kwimura igihe cyigihe, ndetse nibintu bizagaragara hepfo.Nyuma yigihe runaka, imikoranire idahwitse izakomeza hamwe.

Ubusanzwe umutwaro uboneka mumashanyarazi manini (capacitive and inductive) inrush current, arc yakozwe izatera ibintu bifatika.

Kuburyo bukomeye kandi bubiri gusa:

Menyesha kurinda umutekano hamwe nibikoresho byoherejwe nka silver, tin oxyde, silver tungsten cyangwa AgCu mugukoresha contact.

Mubisanzwe imiterere ihanamye igaragara muri cathode, imiterere ya convex igaragara muri anode.
