Ukuvikelwa kwenjini ngokuzenzakalelayo: injongo nenjongo

Idivayisi yokuvikela imoto isetshenziselwa ukuvikela i-windings kusuka esifundeni esifushane, ukugcwala ngokweqile, futhi nalapho esinye sezigaba ezintathu zesifunda sokuhlinzeka siphukile. Isimo sokugcina senzeke lapho imishini yokushintsha ingaphumeleli noma ukuthembeka kwekhebula elixhuma umzila we-boron kusifunda esithintekayo kuphukile.

Ukuqokwa

I-unit yokuvikela imoto isethwe njengesixhumanisi sokuqala kwinethiwekhi yokunikezela. Ngaphezu kwalokho, i- starter i-starter starter iyatholakala , emva kwalokho ukulayishwa kwe-thermal kungasetshenziswa ngokungeziwe . Amamodeli wanamuhla anamandla okulungisa i-cutoff yamanje.

Ngokuvamile, izinhlobo ze-automata ezibuzwayo zisetshenziselwa ukuvikela ama-motors amathathu. Ukudonsa ngakunye kufinyelela ekuthintaneni kwayo, kodwa idivayisi ivaliwe kuzo zonke izigaba. Lesi simiso sokusebenza sihlukanisa idivayisi kusuka ekushintsheni kohlobo B no-C. Amamori ahamba phambili aqala ngaphansi komthwalo ngaphansi kwezimo ezinzima. Kulesi simo, amanje wokuqala ngokuvamile adlula inani lokubiza kuze kube izikhathi ezingu-6. Izinguquko ezijwayelekile zizosebenza masinyane, i-automaton izovalwa ngemuva kokunyuka okuqhubekayo emzimbeni.

Amapharamitha wedivayisi kagesi

Ukukhethwa kwesivikelo semoto kuqala ngezici ezilandelayo:

• I-Motor operation yamanje.
• Inani lezintambo zokunikezela.
• Inombolo yemimoya.
• Isici esibalulekile yikhono lomshini wokunqamula ukuxhumeka kwamanje okwamanje. Emishini evamile ayidluli ku-6 kA, ezinguqulweni zakamuva idlula i-50 kA. Isikhathi sokuphendula sithathwa ngokucatshangelwa: ukukhetha - kufika ku-1 s, evamile - kufika ku-0.1 s, isivinini esikhulu - akukho ngaphezu kuka-0.005 s.
• Ubukhulu obuningi. Imishini eminingi ixhunywe ngamanxiwa ngebhasi elihleliwe. Ngokuvamile kuyinkinga ukufaka umshini wokuqala ongakolunye uhlangothi.
• Uhlobo lwenqubo yokukhulula: kungenzeka ukuthi ukuvikelwa okushisa nokukhipha amandla kagesi.

Isexwayiso sokungasebenzi kwemoto kagesi

Kubalulekile ukwazi nje ukuthi yimiphi imisebenzi yokuvikelwa eyenziwa yisifunda sokuvikelwa kwezimoto, kodwa futhi ukucabangela ama-nuances ezobuchwepheshe wesifundazwe esixhunyiwe kagesi. Endabeni yokusebenzisa ama-motors aphezulu, amaphutha angenzeka uma i-overcurrent encane igeleza ngokuxhumana okulodwa kokudluliselwa komshini. Ngemuva kokusebenza okude, lokhu kuyoholela ekuhlulekeni kokukhipha. Kuzothatha inkinobho ezwelayo, ekwazi ukwephula isifunda lapho ucingo luvutha.

Amanye ama-motors ayabalulekile ekulahlekelweni okwesikhashana kwesinye sezigaba zokudla. Ngisho noma kusetshenziselwa ukuvikelwa kwezimoto ezizenzakalelayo nokuvikelwa okushisayo, kuzodingeka ukuthi ufake amamodeli avaliwe lapho kuphelelwa amandla okuphakela komunye wabaxhumana nabo. Ngakho-ke, amadivaysi anjalo anesakhiwo esiyinkimbinkimbi, esithinta izindleko zabo. Abakhiqizi abancoma kakhulu ukuxhuma izifunda zamandla eziningana kudivayisi eyodwa.

Izakhiwo ezengeziwe zokushintsha imishini

Isiteshi sokuvikelwa kwezimoto senzelwe ukusebenza kuhlobo oluthile lwamazinga okushisa amabi. Ngemuva kokudlula umkhawulo ophezulu obekwe umenzi, ama-alamu amanga angenzeka. Uma inkinobho ifakwa endaweni ebandayo kakhulu, ngeke ivalwe ngesikhathi esifanele nhlobo. Ngakho-ke, uma kunesidingo, abafakisi bazohlinzeka isinxephezelo esifanele sezobuchwepheshe.

Endaweni yokusebenza kungase kube nezimo lapho umshini uqobo ungasebenzi, futhi izakhi ezisele zihlala zisebenza. Kwamanye amamodeli, umsebenzi wokuvikelwa kwiphaneli langaphambili le-breaker circuit inikezwa. Lesi yisilinganiso sesikhashana ngaphambi kokufaka idivayisi entsha ukuze kuqinisekiswe ukulethwa okuqhubekayo kwemikhiqizo. Nokho, kunengozi yokulimaza into ebiza kakhulu - injini.
