Iqembu lomthwalo linezici zokuphepha, ukwethembeka, ukusebenza okulula kanye nempilo ende yesevisi.Ukuqonda ukwakheka kanye nomsebenzi wamasekhethi wesici sokulawula, ukupholisa, nokulayisha kubalulekile ukuqonda ukuthi iqembu lomthwalo lisebenza kanjani, ukukhetha iqembu lokulayisha lohlelo lokusebenza, nokugcina iqembu lomthwalo.Lezi zifunda zichazwe ezigabeni ezilandelayo
Ukubuka konke kokugijima kweqembu le-Eak
Iqembu lomthwalo lithola ugesi kugesi, liwuguqule libe ukushisa, bese likhipha ukushisa kuyunithi.Ngokusebenzisa amandla ngale ndlela ibeka umthwalo ohambisanayo ekunikezeni amandla.Ukuze wenze lokhu, iqembu lomthwalo lithatha inani elikhulu lamanje.Ibhange elingu-1000 kw, 480 v lizoqhubeka nokumunca ama-ampere angaphezu kuka-1200 ngesigaba ngasinye futhi lizokhiqiza amayunithi okushisa ayizigidi ezingu-3.4 ngehora.
Iqembu lokulayisha livame ukusetshenziswa
(1) ukufaka ingcindezi ekuphakelelweni kukagesi ngezinjongo zokuhlola, njengokuhlola ijeneretha ngezikhathi ezithile
(2) ukuze kuthinteke ukusebenza kwesiguquli esiyinhloko, isibonelo, ukuhlinzeka ngomthwalo omncane ukuvimbela ukunqwabelana kwezinsalela zegesi ekhishwayo engashile enjinini kadizili.
(3) lungisa isici samandla sesekethe kagesi.
Iqembu lomthwalo lenza umthwalo ngokuqondisa okwamanje kusici somthwalo, esisebenzisa ukumelana noma eminye imiphumela kagesi ukuze kudle amandla.Kungakhathaliseki ukuthi iyini injongo yokugijima, noma yikuphi ukushisa okukhiqiziwe kufanele kukhishwe eqenjini lokulayisha ukuze kugwenywe ukushisa ngokweqile.Ukususwa kokushisa kuvame ukufezwa i-blower kagesi esusa ukushisa eqenjini lomthwalo.
Isekhethi yesici somthwalo, isifunda sesistimu yokuvuthela kanye nesekhethi yedivayisi elawula lezi zici zihlukene.Umfanekiso 1 uhlinzeka ngomdwebo owenziwe lula womugqa owodwa wobudlelwano phakathi kwalezi zifunda.Isifunda ngasinye siphinde sichazwe ezigabeni ezilandelayo.
Umjikelezo wokulawula
Ukulawulwa kweqembu lomthwalo okuyisisekelo kuhlanganisa ukushintshwa okuyinhloko kanye neswishi elawula isistimu yokupholisa kanye nezingxenye zomthwalo.Izingxenye zokulayisha ngokuvamile zishintshwa ngokuhlukana kusetshenziswa iswishi esizinikele;lokhu kuvumela opharetha ukuthi asebenzise futhi aguqule umthwalo ngokuqhubekayo.Isinyathelo sokulayisha sichazwa yikhono lesici esincane somthwalo.Iqembu lokulayisha elinesici esisodwa sokulayisha esingu-50kW kanye nezinto ezimbili ezingu-100kw linikeza ithuba lokukhetha umthamo ophelele ongu-50,100,150,200, noma 250KW ngokulungiswa okungu-50kW.Umfanekiso wesi-2 ubonisa umjikelezo wokulawula iqembu lomthwalo owenziwa lula.
Ngokuphawulekayo, i-Load Group Control Circuit iphinde inikeze amandla nokusayinda kwenzwa eyodwa noma ngaphezulu lokushisa ngaphezulu namadivayisi okuphepha amaphutha komoya.Owokuqala uklanyelwe ukuthola ukushisa ngokweqile eqenjini lomthwalo, kungakhathaliseki ukuthi iyini imbangela.Okwakamuva amaswishi acishwayo kuphela lapho ezwa umoya ugeleza phezu kwesici somthwalo;uma inkinobho igcinwa, ugesi awukwazi ukugeleza ku-elementi eyodwa noma ngaphezulu yokulayisha, ngaleyo ndlela ivimbele ukushisa ngokweqile.
Isifunda sokulawula sidinga umthombo wamandla kagesi wesigaba esisodwa, ngokuvamile amavolthi angu-120 ku-60 hertz noma ama-volts angu-220 ku-50 hertz.Lawa mandla angatholakala ekunikezeni amandla kwesici somthwalo ngokusebenzisa noma yiziphi iziguquli ezidingekayo zokuya phansi, noma kugesi wangaphandle wesigaba esisodwa.Uma iqembu lokulayisha lihlelelwe ukusebenza kwe-dual-voltage, iswishi isethwe kumjikelezo wokulawula ukuze umsebenzisi akwazi ukukhetha imodi ye-voltage efanele.
Uhlangothi lomugqa wamandla okokufaka wesekethe yokulawula ukuvikela i-fuse.Uma iswishi yamandla okulawula ivaliwe, isibonisi samandla okulawula siyakhanyisa ukukhombisa ubukhona bokunikezwa kwamandla.Ngemva kokutholakala kwamandla okulawula ukutholakala, opharetha usebenzisa iswishi yokuqalisa i-blower ukuze aqale uhlelo lokupholisa.Ngemuva kokuthi i-blower inikeze isilinganiso esifanele sokugeleza komoya, ukushintshwa komoya okuhlukile okukodwa noma ngaphezulu kwangaphakathi kuthola ukugeleza komoya futhi sekuseduze nokubeka i-voltage kumjikelezo wokulayisha.Uma lingekho “Iphutha lomoya” futhi kutholwa ukugeleza komoya okufanele, iswishi yomoya ngeke ivalwe futhi nesibani senkomba sizovulwa.I-master load switch ngokuvamile inikezwa ukuze kulawulwe wonke umsebenzi wesici esithile somthwalo noma iqembu lamaswishi.Iswishi ingasetshenziselwa ukwehlisa ngokuphepha yonke imithwalo esetshenzisiwe, noma njengendlela elula yokuhlinzeka ngomthwalo ogcwele noma othi "Spread" ekunikezeni amandla.Amaswishi okunyathela ukulayisha akala izingxenye ngazinye ukuze zinikeze umthwalo odingekayo.
