-Phase Single umaphuli yesekethe: inkcazelo device kunye uqhagamshelwano

Isixhobo yokhuselo zombane iqhelekileyo a ndingumgqithi yesekethe umgca ukukrazula -phase.

ukuqashwa

Ikhubaza beesekethe kwenzeka xa yangoku udlula ixabiso rated. I aphezulu oko, kungona isantya impendulo. Ngaphezu koko, lo matshini icinyiwe ngexesha short circuit xa kukho ngoku enkulu kakhulu kwisekethe ezikhuselweyo. Apha, i umda kwenzeka nangoko.

Xa block Isitimela enxulumene neziseko nga kambisiseni xikombiso xa, apho abasebenzisi eziliqela ngaxeshanye enxulumene namandla. Ngoku oko idlula ixabiso ubuso kunye zikagesi baqalisa ukuba shushu. Ukuba ngaba oplavilis, ixesha oluzenzekelayo ikwacima wesekethe.

Icebo asabela lukhethiwe ezinjalo ukuba ngcingo zingatsalelwa ebilayo. Le ungumgqithi zeesekethe likhusela umthwalo enxibeleleneyo. Ke kaloku indoda kwimiphumo ngqo yangoku yombane, yena ngokwakhe akanako ukuzisindisa. Ukuze wenze oku, sebenzisa izixhobo zokhuselo.

isimiso ukusebenza

Nangona obonakala ulula, single-isigaba umaphuli yesekethe sisixhobo entsonkothileyo. Kunokuba elektroniki, kodwa electro-mechanical uyilo luqhelekileyo yamandulo.

terminal input usoloko phezulu kwefowuni. Elidityaniswe kuyo qha elimisiweyo. I-terminal output esezantsi liqhagamshelene qha ezinokususwa ongentla ngako ukukhululwa wobushushu ngokohlobo estrip bimetallic. Kwakhona wacofa isixhobo electromagnetic nokukhubeka.

Le spring zoqhagamshelwano ezinokususwa ilungiswe kwizikhundla ezimbini esitalini - ku vula iphinde ivale kwamazwe. Zenzekelayo ukuseta ukusebenza ngesandla nge lempumelelo. Cima ngokuzenzekelayo. Kwakhona Isixhobo zingasetyenziswa njenge iswitshi.

Ukusebenza oqhelekileyo, ngoku wombane aqukuqela iqela loqhagamshelwano automaton ezivaliweyo. Xa edlula wesekethe wesiqhelo igcwele. Ukuba oku kwenzeka elide esityeni bimetal ngcembe itshiswa bend, ukutyhala indlela lever release. Ngaloo ndlela Zenzekelayo kwabangela, abafowunelwa ezivulekileyo kunye wesekethe yaphulwe.

Ukuba kwenzeka short circuit, yindlela release magnetic kubangelwa, nangoko ukujika amandla off. Xa oku umfowunelwa kwenzeka phakathi yintlantsi uyila arc yombane, nto leyo damped phakathi iipleyiti indawana ekhethekile.

Ekuhambeni kwexesha, abafowunelwa baqala kunokutshiseka. Lo matshini yenzelwe ikakhulu ukukhusela iintambo rhoqo ungayisebenzisa njengendlela iswitshi ayikhuthazwa. miyalezo beesekethe zisetyenziswa ululayite.

Indlela ukukhetha umatshini ekunene?

-Phase Single umaphuli yesekethe zikhethwa kwicandelo umnqamlezo ucingo kunye iimpawu umthwalo eziboniswe iileyibheli kwicala phambi ifowuni.

Kuba ezi parameters, ungakhetha umatshini oyifunayo.

1. E.NEXT - uphawu (ngaphezulu) lubonisa abenzi. Kuyanconywa ukuba ukukhetha iintlobo ezaziwayo-kakuhle. Kufuneka ukhokelwe kukuba inqanaba isixhobo eyahlukileyo kakhulu kwezinye izixhobo zombane.
2. 220/400 - 50 Hz - mqondiso kuthetha ukuba umatshini isebenzayo networks elinye-lesigaba ontlantlu-ntathu kunye rhoqo 50 Hz.
3. 4500 - ixabiso zangoku kumda ka A apho umaphuli aya uhambo ubuncinane kanye (zevenkile yeklasi - 3).
4. C16 - time-ngoku iimpawu (C) kuthetha ukuba indlela nokukhubeka kubangelwa amaxesha ezintlanu rated lwangoku. It ifanele khulu izixhobo kunye nokukhanya. Inani 16 ibonisa ihlelo. 16A single-phase umaphuli yesekethe asikusebenzeli ixesha elide xa ixabiso amps zangoku 16. Ukuba linyuke nge-13%, i-off ikhonkco liya kwenzeka ngeyure. Okuya uba mkhulu umsantsa ixabiso, kokukhona akhawulezayo msebenzi.

Ngamayelenqe kwiingcingo yokuhlala adla ngokusetyenziswa eklasini, apho umda ngoku amaxesha 3 ixabiso eliyimali. Ukuba usoloko ukuqhagamshela oomatshini ndidi B no-C uya kusebenza kuqala. Ngaloo selectivity kuqinisekiswa izixhobo zokhuseleko, xa zonke ezinye iimpawu ezifanayo.

Zenzekelayo utshintsho-Inqanaba: ixabiso

Devices ne kwipali omnye engambi kwimigangatho koomatshini ubukhulu kuluhlu.

Ukuba uthelekisa ixabiso ezineempawu ezifanayo, kubonakala ukuba lo single-isigaba liphantsi. Nabavelisi miyalezo zeesekethe ngoku kwaye ungasoloko ukukhetha iindleko ezifanelekileyo kunye nomgangatho uphawu.

On a single-phase umaphuli yesekethe eMoscow inika uluhlu olubanzi iimveliso ngamaxabiso afikelelekayo. Ungakhetha isixhobo ethembekileyo lophawu ethandwa ABB ukususela 147 engange. nangaphezulu, ukusuka nezibonda kwesinye ukuya kwisine.

umatshini Ixhuma

-Phase Single umaphuli yesekethe shelwe lenjongo ngaphandle kwezithuthi eyakhelwe ngaphakathi ulilo. Le fowuni ukhwele Din-kaloliwe kunye Kwasika esiswini ezinzileyo.

Zenzekelayo ukuseta ngolu hlobo.

1. Ngaphambi kokuba uxhume omnye-phase umaphuli zeesekethe, swi de-amandla kunye nokwamkelwa amanyathelo okuthintela unikezelo lwamandla ngengozi.
2. Machine efakiweyo kwindawo ethile. Phambi inani lezihlalo engenanto, zokumisa umdla metal zifakelwe.
3. Ixhume le ukuphela ongentla kwamandla, umzantsi - kwisekethe ezikhuselweyo. Le iingcingo zinendlela ezihambe ngayo ngaphandle ukugoba ezibukhali kwaye akhululeke. iziphelo balahleke baxhotyiswa kunye ferrules ukuba crimped Crimper.
4. Ukuba kukho amanye oomatshini kunye nosasazo kwesigaba-isicelo ivili Oxhumayo ikama okanye ntofo kwi ezintambo ezimbini. Ukuqinisa iqinisiwe, kodwa hayi namandla kakhulu.
5. Ngomhla sihlangu walifaka ize ingqinwe ubukho ombane kwi igalelo kunye neziphumo iterminal matshini.
6. Kwi full wesiphaluka uphawulwe kwisekethe ezikhuselweyo.

imposiso yokukhetha

1. Asimele kugxininisa ngamandla iyonke kwabathengi. Okokuqala kuyimfuneko ukubala iintambo ukuba bakhuselwe overload.
2. Kwi yonke imigca oomatshini esinye ifakiwe. Kuba zokuphuma baya kuza bevela lwangoku 25 A ukukhanyisa - 16 A.
3. Okokuqala zonke izixhobo ezikhethiweyo ukusebenza nokuthembeka, uze emva koko - ngexabiso.

isiphelo

-Phase Single umaphuli beesekethe yenzelwe ukukhusela iintambo zombane zombane. iimpawu zayo kufuneka athobele umnqamlezo-candelo ababhexeshi kunye imithwalo. ukusetyenziswa ngokufanelekileyo koomatshini yeendidi B no C iqinisekisa operation echanekileyo. Ngokuba ukhetho oluchanekileyo kubalulekile ukuqonda ikhowudi kwi phambi ifowuni.
