Umbutho kunye nokuSetyenziswa kweZibonelelo zoMbane woTshintsho, abaQhagamshelana, ii-Frequency Inverters, kunye neeRelays

Kwiinkqubo zanamhlanje zombane wombane, izixhobo zombane ezitshintshayo (SMPS), abafowunelwa, ii-frequency inverters, kunye nokuhanjiswa kwendima nganye ebalulekileyo, kwaye ukusebenza kwabo ngentsebenziswano kwenza ulawulo olubhetyebhetye ngakumbi nolusebenzayo lwezixhobo zombane. Eli nqaku liza kuhlolisisa ubudlelwane phakathi kwezi zixhobo kunye neendlela zabo zokusetyenziswa.

I. Isishwankathelo seSixhobo

1. Ukutshintsha uBonelelo lwaMandla (SMPS)
   Umbane otshintshayo sisixhobo esisebenzayo sokuguqula amandla esilawula kwaye sizinzise amandla ombane wokuphuma ngokutshintsha ngokukhawuleza amacandelo e-elektroniki (afana neetransistors). Xa kuthelekiswa nezixhobo zombane eziqhelekileyo, ukutshintshela umbane kukubonelela ngobuchule obuphezulu kunye nobukhulu obuncinci kunye nobunzima. Umthetho-siseko ongundoqo wokusebenza konikezelo lwamandla okutshintsha ubandakanya ukulawula ukuhanjiswa kwamandla obonelelo lwamandla ngokutshintsha okukhawulezileyo kwezinto zokutshintsha kombane, ngaloo ndlela kufezekiswe uguqulo lwamandla ombane kunye nokuzinzisa.

   

2. Umnxibelelanisi
   I-contactor sisitshixo sombane esizenzekelayo esilungele ukudibanisa rhoqo okanye ukuqhawula iisekethe ze-AC kunye ne-DC kunye neesekethe zokulawula umthamo omkhulu ukusuka kude. Ayenzi nje kuphela ukusebenza okuzenzekelayo okude kunye nemisebenzi yokukhusela ukukhutshwa kwe-undervoltage kodwa ikwaqhayisa amandla okulawula aphezulu, ukuthembeka, ukusebenza kakuhle, kunye nobomi benkonzo ende.

   
   
   

3. Inverter rhoqo
   I-frequency inverter sisixhobo esilawula isantya sokusebenza semoto yombane ngokutshintsha unikezelo lwamandla ombane, ingakumbi usetyenziso olufuna isantya esichanekileyo kunye nolawulo lwetorque. I-frequency inverter kuqala iguqula i-AC ibe yi-DC, kwaye emva koko isebenzisa i-inverter yesekethe ukuguqula i-DC ibuyele kwi-AC kunye ne-adjustable frequency, ngaloo ndlela iqhuba imoto yombane.

4. Udluliselo
   I-relay sisixhobo sokulawula umbane esibangela ukuba inyathelo elimiselweyo litshintshile kwisixa esilawulwayo kwisiphaluka sokuphuma kombane xa utshintsho kwi-input quantity (i-stimulus) ifikelela kwiimfuno ezichaziweyo. Iseka ubudlelwane obusebenzisanayo phakathi kwenkqubo yolawulo (i-input circuit) kunye ne-controlled system (output circuit).

   

II. Uhlahlelo loMbutho

1. Ukutshintsha uBonelelo lwaMandla kunye noQhagamshelwano
   Ukunikezelwa kwamandla okutshintsha kunika umbane ozinzileyo we-DC kwi-contactor, ukuqinisekisa ukubandakanyeka okuthembekileyo kunye nokukhululwa koqhagamshelwano. Kwiinkqubo zokulawula umbane, ukunikezelwa kwamandla okutshintsha ngokuqhelekileyo kusebenza njengombane oyintloko, ukubonelela amandla ombane azinzileyo kuyo yonke inkqubo.

2. Umnxibelelanisi kunye ne-Frequency Inverter
   I-contactor idlala indima ekudibaniseni okanye ekuqhawuleni ukunikezelwa kwamandla kwimoto yombane kwiinkqubo zokulawula i-inverter frequency. Xa i-frequency inverter idinga ukuqalisa okanye ukumisa i-motor yombane, ilawula ukubandakanyeka kunye nokukhululwa kwe-contactor ukufezekisa uqhagamshelwano lombane okanye ukuqhawula. Ukongeza, umnxibelelanisi unokukhusela i-inverter frequency kwiimpazamo ezinje ngokugcwala kwemoto.

3. I-Inverter rhoqo kunye ne-Relay
   Ii-inverters ze-frequency inverters zihlala ziqhagamshelwa kwaye zilawulwa kunye nezinye izixhobo zombane ngokusebenzisa iireyiyidi. Ngokomzekelo, ii-relays zinokulawula ukuvulwa kunye nokuvalwa kweesekethe ezinxulumeneyo ngexesha lokuqalisa kunye neenkqubo zokuvala i-inverter frequency. Ngaphaya koko, xa i-inverter ephindaphindayo ibona iimpazamo ezinje ngokugcwala kwemoto okanye i-overcurrent, inokukhupha imiqondiso ye-alam okanye inqumle unikezelo lwamandla ngokuhanjiswa.

4. Isicelo esiDityanisiweyo
   Kwizicelo ezisebenzayo, izixhobo zombane zokutshintsha, ii-contactor, ii-frequency inverters, kunye nee-relays zihlala zisetyenziswa ngokudityaniswayo ukwenza inkqubo epheleleyo yolawulo lombane. Ngokomzekelo, kwiinkqubo zokubonelela ngamanzi ngoxinzelelo oluqhubekayo, ii-PLCs ziyakwazi ukulawula ii-inverters ze-frequency ukuze zifezekise ukusebenza okuguquguqukayo kweempompo, ngelixa ii-contactors kunye nee-relay zisetyenziselwa ukudibanisa umbane kunye nokuqhawula, imisebenzi ye-alarm yempazamo, kunye nokunye.
