Ma relay amagalimoto ndi zigawo zazikulu zamakina amagetsi agalimoto.Kuyatsa magalimoto, ma wiper, zoyambira, zoyatsira mpweya, mipando yamagetsi, zitseko zamagetsi ndi mazenera, zida za anti loko, zowongolera kuyimitsidwa, makina omvera, ndi zina zambiri zimafunikira ma relay.Ndizimodzi mwazinthu zamagetsi zomwe zimagwiritsidwa ntchito kwambiri pamagalimoto, zomwe ma electromagnetic relay ndi mtundu wakale kwambiri komanso wogwiritsidwa ntchito kwambiri.Ndi chiyani ndipo zimagwira ntchito bwanji?M'nkhaniyi, tilowa m'dziko la magalimoto oyendetsa magalimoto ndikufufuza mfundo zawo zogwirira ntchito ndi ntchito wamba.

1. Kodi Car Relay ndi chiyani?

Ma relay amagalimoto amagwiritsidwa ntchito kwambiri ma switch owongolera omwe amawongolera mafunde akulu okhala ndi mafunde otsika pomwe amateteza masiwichi.Kwenikweni, zimalola kuwongolera katundu wokulirapo wamagetsi ndi ma siginecha ang'onoang'ono amagetsi.Chifukwa cha kuchuluka kwazomwe zimafunikira pano, zosinthira monga nyanga, zoyambira, nyali zakutsogolo, ndi zina zotere zimatha kuyambitsa kugwedezeka kwamagetsi ndi kukokoloka.Ngati pali relay, kachulukidwe kakang'ono kokha kamene kamadutsa pa switch switch ndizovuta kupangitsa kukokoloka kwa switch.Chifukwa chake, nthawi zambiri timanena kuti ma relay ndi mlatho pakati pa mabwalo ochepera mphamvu ndi mabwalo amphamvu kwambiri.

2.N'chifukwa Chiyani Magalimoto Amafunikira Ma Relay?

Ma relay amagalimoto ndi ofunikira chifukwa amalola kugwiritsa ntchito ma switch ang'onoang'ono komanso otsika komanso mawaya pamagawo owongolera magalimoto.Izi zitha kuchepetsa katundu pazingwe zamawaya agalimoto ndi masiwichi, ndikuletsa kutenthedwa ndi kuwonongeka kwamagetsi.Kuonjezera apo, malo a relay akhoza kukhala pafupi ndi zigawo zomwe zimayendetsa, potero kuchepetsa kutsika kwa magetsi pa mawaya.

3. Mapangidwe a Car Relay

Zolumikizirana zamagalimoto nthawi zambiri zimapangidwa ndiIron Core, Coil, YOKE, Armature, Spring, Contact, etc. kukhudzana amagawidwa muKusuntha ContactndiContact Yokhazikika (Stationary Contact).Malingana ndi mtundu wa kukhudzana, ma relay nthawi zambiri amagawidwa m'mitundu iwiri:

1. Pangani & Kuswa Relay

Amadziwikanso kutiMtengo wa SPST(Ndili Limodzi, Kuponya Kumodzi).Pali mapini 4 (kapena ma terminals) pathupi lokhala ndi dera limodzi lapamwamba komanso kulumikizana.Kulumikizana kumatsegulidwa kapena kutsekedwa kutengera ngati kutumizirana kumapuma kapena kupatsidwa mphamvu.

● NC:Ngati kukhudzana kwatsekedwa pamene cholozeracho chili pamalo oyima, cholumikiziracho chimatchedwa Mwachizolowezi Chotsekedwa.

●NO: Ngati kukhudzana kutsegulidwa pamene relay ili pamalo oyima, relay imatchedwaNthawi zambiri Open. Ma relay awa ndi omwe amapezeka kwambiri.

2. Changeover Relay

Amadziwikanso kutiMalingaliro a kampani SPDT(Mzati umodzi, Kuponya kawiri).Pali5 pin(kapena ma terminals) pathupi, pali zolumikizira ziwiri zolumikizidwa ku terminal wamba.Ma relay ali ndi mabwalo awiri, imodzi imatsekedwa pamene relay ili pampumulo, ndipo ina imatsekedwa pamene relay ipatsidwa mphamvu.

Chithunzi chotsatira chikuwonetsa mawonekedwe amkati a Changeover Relay.

4. Kodi Car Relay Imagwira Ntchito Bwanji?

Chithunzi chotsatirachi chikuwonetsa ntchito yotumizirana mauthenga.Kuti mumvetsetse, cholumikizira chowoneka bwino chamagetsi chaperekedwa apa.Mumtundu uliwonse wa relay yamagalimoto, zigawo zazikuluzikulu ndi coil, armature, ndi kulumikizana.Waya amazunguliridwa ndi maginito, kupanga maginito amagetsi.Mukapereka mphamvu ku coil, imapatsidwa mphamvu ndikupanga gawo lamagetsi.Chombo ndi chinthu chosunthika chomwe ntchito yake yayikulu ndikutsegula kapena kutseka zolumikizirana.Zimamangirizidwa ndi kasupe, kotero pansi pazikhalidwe zogwirira ntchito, zidazo zimabwerera kumalo ake oyambirira.

1. Mphamvu-Mmwamba State

Ngati gwero lamagetsi lipatsa mphamvu koyiloyo, koyilo yamagetsi ya relay imapatsidwa mphamvu ndipo imapanga kusinthasintha kwa maginito kolingana ndi komwe kumadutsamo.Mphamvu ya maginitoyi imakopa zida zamagetsi ku electromagnet, kotero kuti kusuntha ndi kuyima kumakhala pafupi wina ndi mzake, monga momwe chithunzichi chikusonyezera.Kulandilako kukalimbikitsidwa, NO terminal kulumikizana pomwe kulumikizana kwa NC kumakhala kuyandama.

2.State-Off State

Pamene kulibe magetsi ku koyilo yamagetsi ya relay, palibe maginito otuluka, kotero kuti chombocho chimakhala choyima.Chifukwa chake, kulumikizana konseko sikunasinthe ndipo pali kusiyana kwapang'ono kwa mpweya pakati pa omwewa.Mwanjira ina, ma NC amalumikizana wina ndi mnzake pomwe koyilo yazimitsidwa.

5. Kugwiritsa Ntchito Wamba kwa Car Relays

Kutumiza kwa magalimoto kuli ndi ntchito zingapo, kuphatikiza:

Woyambitsa:Kuyambitsa injini kumafuna kuchuluka kwapano kuti muyambitse injini.Relay imalola chosinthira choyatsira kuti chiwongolere katundu wapamwambawu.

Nyali zakutsogolo:Nthawi zambiri ma relay amagwiritsidwa ntchito kuwongolera nyali zakutsogolo, kuwonetsetsa kuti alandila mphamvu zokwanira ndikuletsa kutsika kwamagetsi komwe kungayambitse kuyatsa.

Pampu yamafuta:Pampu yamafuta imafunikira kuchuluka kwapano kuti ipereke mafuta ku injini.Relay imatsimikizira kuti imalandira mphamvu yofunikira.

Nyanga:Nyanga zamagalimoto zimafuna kuchuluka kwamakono.Relay imalola batani la nyanga kuwongolera lipenga.

Zinganenedwe kuti ma relay a magalimoto ndi ngwazi zosadziwika mumakampani opanga magalimoto.Amapereka njira yothandiza komanso yothandiza yoyendetsera panopa m'galimoto, kukulolani kuti mugwiritse ntchito zida zamakono popanda kudzaza mphamvu zamagetsi.Typhoenix amapereka zosiyanasiyanama relay amagalimotokuteteza galimoto yanu.
