Inqanaba lesithathu: ekubaleni idayagramu amandla iintambo

Elowo endaweni yokubutha kucacile ukuba, iziphaluka ezinjalo. Iiflethi ezi 99% ezi-, apho wangoku anikiwe umsebenzisi-nkonzo yi ucingo enye, kwaye ibuyiselwe kwi kwelinye (zero). Uthungelwano ontlantlu-ntathu i inkqubo yokudlulisela i umbane ophuma kwi ngcingo ezintathu ukuya nokubuya omnye. Apha, umqhubi wokubuyiswa akukho nekhabhoni ngenxa kwisigaba shift yangoku. Umbane generator eliqhutywa yi njengokujikeleza yangaphandle drive.

Ukwanda koxinizelelo kwisekethe kukhokelela ekwandeni lwangoku ayahamba jiko generator. Ngenxa yoko, lo mhlaba otsalayo ngakumbi ukuxhathisa njengokujikeleza drive shaft. Inani revolutions iqala ukunciphisa nesantya isilawuli ojikelezayo Ulothetha ukwanda drive kwamandla, umzekelo lokuqeshisa amafutha ngakumbi injini yokutsha. Inani revolutions sinciphile kwaye umbane.

inkqubo phase-Three yi inxitywe 3 ngamandla electromotive yobuninzi efanayo kunye kwisigaba ukududulelwa ° 120.

Amandla Uyamano iimpawu ezithile zendlu

Abantu abaninzi bakholelwa ukuba network ontlantlu-ntathu ekhaya kwandisa ukusetyenziswa kwamandla. Enyanisweni, lo umda inkampani ngombane esetiweyo kwaye ugqibe zinto:

• ikhono le mpahla;
• Inani labathengi;
• imigca karhulumente kunye nezixhobo.

Ukuthintela kwama amandla phase unbalance kufuneka ukulayisha ngokulinganayo. Ukubalwa kwenkqubo ontlantlu-ntathu ufumana ngayo, ngenxa yokuba akunakwenzeka ukuba ukufumanisa ukuba zeziphi izixhobo ezidityaniswe okwangoku. Ukufumaneka kwezixhobo ngokwentshukumisa okwangoku kukhokelela ekwandeni ukusetyenziswa kwamandla abo start-up.

Distribution ibhodi yombane yoqhagamshelo ontlantlu-ntathu luthathiwe ezinkulu kuno ngamandla ezi-. Ezahlukeneyo kunye nokufakwa indawo yolawulo encinane, yaye abanye - lweplastiki nge kwisigaba ngasinye kwaye outhouses.

ukufumana uqhagamshelwano lomqolo iqaphelwa unendlela umgca ngaphantsi komhlaba kunye phezulu. Kukhethwa inikwa yokugqibela ngenxa imali encinci emisebenzini, libya indleko uqhagamshelwano kunye lula ukulungiswa.

Ngoku ke uqhagamshelwano umoya ungenziwa lula ngoncedo wire igqunyiwe self-axhasayo (SIW). Ubuncinane abaqhubi aluminium cross-candelo 16 mm ^2, nto leyo eya kuba ngokwaneleyo esima enkulu ikhaya labucala.

SIP ukhwele exhasa kunye eludongeni lwendlu kunye kwizibiyeli ankile kunye yamasango. Dibanisa umoya umgca engundoqo kunye ungeno cable kwi swi ekhaya izihlanganisi ukugqojozwa wenza emseleni Parallel. Intambo buyasuswa yokugquma noncombustible (VVGng) kwaye lwenziwa kumbhobho wesinyithi lifakwa eludongeni.

uqhagamshelo Air of umbane ontlantlu-ntathu ekhaya

Xa umgama ukusuka inkxaso elikufutshane ngaphezulu kwe-15 m kufuna ufakelo ungadibanisa omnye umhlathi. Oku kuyimfuneko ukuze kuncitshiswe umthwalo, okukhokelela unokukhawuleza okanye wire eyaphukileyo.

Ukuphakama kwenye indawo uthimbo 2,75 m okanye ngaphezulu.

kagesi distribution ikhabhinethi

ku-mbane ontlantlu-ntathu uxhulumaniso lusenziwa kwi projekthi, evela ngaphakathi endlwini ukwahlulwa ibe ngamaqela abathengi:

• ukukhanyisa;
• iziseko;
• ezinye izixhobo ezinamandla.

Ezinye uxinzelelo banoku cinywa umsebenzi yesondlo kwelinye.

abathengi Amandla kubalwa ukuze iqela ngalinye, apho umnyulwa kufuneka icandelo wire: 1.5 mm ² - ukuba ukhanyiso, ukuze 2.5 mm ² - ukuba lo walivala ithende ^no-2 ukuya kwi-4 mm - Ukubhala sisixhobo esinamandla.

Iingcingo zombane uyakhuseleka elifutshane-beesekethe kunye ukucima kombane circuit breakers protection.

imitha yombane

Ukuba kukho umzobo kweentambo efunekayo isixhobo wekhadi le losetyenziso lombane. phase-3 Isibali unako kuqhagamshelwa ngokuthe ngqo kwi network (live) okanye nge transformer ombane (polukosvennoe), apho reading nanda yi ngumlingani.

Kubalulekile ukuba ukuthobela umyalelo wombane, apho odd amanani - oko ukutya, kwaye nkqu - umthwalo. imibala Wire kubonisiwe kule nkcazelo, yaye le sekethe ibekwe kwi ngasemva sixhobo. Igalelo ehambisana output ontlantlu-ntathu counter elijongene umbala omnye. Inkqubo eqhelekileyo ngokujoyina xa kuqala ezayo lesigaba kunye wire yokugqibela - zero.

phase-3 kwiimitha uxhulumaniso ngqo ekhaya idla yenzelwe ukuba emandleni ukuya ku-60 kW.

Ngaphambi kokukhetha imifuziselo multirate kufuneka bavumelane kwinkampani ugesi. izixhobo Modern kwenza kube lula ukubala intlawulo rater yombane kuxhomekeke ixesha losuku, ukuba abhalise kwaye babhale ixabiso yemveliso ngelo xesha.

parameters Ubushushu yesixhobo ekhethiweyo kangangoko kunokwenzeka. Kwi-avareji, kususela -20 ukuya +50 ° C. elide lezixhobo ncwadana engama-40 ukusuka ekulinganisweni le kweminyaka 5-10.

Counter uhlobene emva intshayelelo emithathu okanye emine kwipali-full wesekethe.

Umthwalo ontlantlu-ntathu

Kuba abathengi ziquka boilers zombane, Motors kunye nezinye izixhobo zombane. Inzuzo ukusebenzisa kwabo ulwabiwo efanayo umthwalo kwisigaba ngasinye. Ukuba kwesigaba sesithathu iquka ezidityanisiweyo umthwalo olunye-phase enamandla ezinomkhethe, oko kunokubangela ukuba kwisigaba ukungalingani. Kulo mzekelo, izixhobo ze-elektroniki aqale kakuhle, kwaye esikhanyisa ukukhanya norhatyazo.

Ephathelene kwisigaba ezintathu ontlantlu-ntathu motor

kwisigaba ezintathu-Work motor umntu asebenza kwizinga eliphezulu kunye nokusebenza. Akudingi ubukho ezingasenza ezongezelelweyo. Kuba umsebenzi oqhelekileyo, kubalulekile ukudibanisa ngokuchanekileyo isixhobo kwaye ulandele zonke iingcebiso.

Idayagram Iimowutha ontlantlu-ntathu ukuya kuthungelwano ontlantlu-ntathu kudala mhlaba otsalayo ejikelezayo, le engathi ezintathu eqhagamshelwe kwi nkwenkwezi okanye nkanyamba.

indlela nganye inamanqanaba alungileyo kwakunye nangalunganga. scheme Star ovumela injini ukuze isebenze kakuhle, kodwa ke umthamo walo lancitshiswa-30%. Le ilahleko ayikho ogudle, kodwa umthwalo ngoku mkhulu kakhulu ekuqaleni.

I-injini ibhokisi lodibaniso, apho miphumela engathi. Ukuba bobathathu, isiphaluka elidityaniswe kuphela yinkwenkwezi. Kunye iiterminal motor ezintandathu nga lidibane nangayiphi na indlela.

kwamandla ngokunyusa

Kuba umnini-ndlu kubalulekile ukwazi ukuba amandla kangakanani aphele. Kulula ukubala zonke izixhobo zombane. Idibanisa onke amandla kwahlulwe isiphumo ka-1000, siye sifumane ukusetyenziswa iyonke, umzekelo, 10 kW. Kuba indlu izixhobo zombane, kwisigaba enye kuphela. Nangona kunjalo, ukusetyenziswa yangoku kuphula kwindlu yangasese, apho kukho indlela enamandla. On isixhobo omnye akhawunti ngenxa kW 4-5.

Kubalulekile ukucwangcisa linqanaba ezintathu-network ukusetyenziswa kwamandla ekusekweni kwayo ukuqinisekisa wolingano le lombane kunye nemisinga.

Indlu iza abane-wire kwisigaba-emithathu cala. ombane mbane we 380/220 V. Phakathi lesigaba umqhubi cala zombane ezidityanisiweyo 220 V. Ngapha koko, oko kusenokuba cwaka umthwalo ontlantlu-ntathu.

Ukubalwa inethweki amandla ontlantlu-ntathu yenziwe ngezavenge. Okokuqala, oko kunilungele ukubala umthwalo nje ontlantlu-ntathu ezifana ngombane kwibhoyila 15 kW induction motor 3 kW. Umthamo lilonke P = 15 + 3 = 18 kW. Isigaba umqhubi yangoku kwemali ngeli I = Px1000 / (√3xUxcosφ). Ukuze amandla cosφ indlu = 0,95. Kufakwe amanani ngamanani ukuya ifomula, sinokuyifumana ubuninzi I yangoku = 28,79 A.

Ngoku kuyimfuneko ukumisela imithwalo ezi-. Masithi ke zenza izigaba P _A = 1.9 kW, P _B = 1,8 kW, P _C = 2,2 kW. umthwalo Ukuxuba ujongwa summation kwaye 23.9 kW. yangoku obukhulu I = 10,53 A (isigaba C). Uyifake ne yangoku kususela umthwalo kwisigaba ezintathu, siye sifumane ndiya _C = 39,32 A. I nemisinga kwi zigaba eseleyo imali endiza _B = 37,4 kW, mna _A = 37,88 A.

Ukubala Amandla ontlantlu-ntathu iluncedo ukuba usebenzise iitafile igunya ngokusekelwe uhlobo lonxibelelwano.

Le miyalezo Pick selungu lokuva kunye nokufakelwa ukujonga emnqamlezweni-candelo.

isiphelo

Kunye noyilo olufanelekileyo kunye nokugcinwa network ontlantlu-ntathu ezilungele kumakhaya. It ikuvumela ukuba babele ngokulungelelana umthwalo kuzo zonke izigaba senginginya nodibaniso nokuba umthamo umthwalo zombane ezongezelelweyo, ukuvumela icandelo iintambo.
