Machine Unipolar: apparatus, iimpawu zobugcisa kunye neempawu zo xhulumaniso

Yombane - a isixhobo ziguquka, i conductive avumelekile umbane kwaye sivala amandla ngaphezu kwexabiso elibekiweyo. Isetyenziswa zokuzikhusela eesekethe zombane overload. Single-kwipali oluzenzekelayo ikhusela ucingo enye kuphela.

Icebo nangemigaqo yokusebenza

Ezona mpawu ziphambili iswitshi zezi isantya wesiqhelo kunye cima ikhompyutha. umatshini Unipolar isebenza ngokusebenzisa iindlela ezimbini: iyunithi uhambo thermal kunye kagesi. Eyokuqala likhubaza wesekethe kwimeko umthwalo elingakumbi amanyathelo ixesha elide, kwaye eyesibini - nangoko, xa elifutshane wesekethe.

isixhobo thermal khuselo isitya bimetal. Xa ngoku kungenela singenelayo, ngaphezu eliphezulu, ngokuthe ngcembe kumo kunye nokugoba, ukutyhala sixhobo, umatshini wavala-off. Emva olupholisa ipleyiti umva endaweni yayo, kwaye switsha kwakhona ilungele ukusebenza. Ukungena ukusebenza, ixhume ngesandla.

Isixhobo magnetic iquka coil ibekwe ngaphakathi engundoqo. Xa edlula ngoku elifutshane-beesekethe kwenzeka ngokubhijela mandrel magnetic intsimi idlulisela, leyo likhubaza umatshini. Apho abafowunelwa zamandla kuvulwa, de-yokuvuselela wesekethe. Njengoko udlule ngoku enkulu, i arc. Iwela le arc kwigumbi, apho iipleyiti zesinyithi enxuseneyo. Ngoncedo lwabo, i arc waphula phezulu kunye disintegrates.

Lo matshini kwakhona sebenzisa njenge switsha ngokuthi kokutshintsha lever ulawulo manual.

Ukusetyenziswa kwe-kwipali eyodwa full yesekethe

Ingcingo indlu iyahlula ngokwamaqela eziliqela. Dibanisa umatshini-kwipali enye evela kwi umsantsa kwesigaba umqhubi. Ibekwe phezu Din zikaloliwe, yaye ngocingo ayo aphezulu vuma umbane ifakiwe. wire wasikhusela liqhagamshelene eligaqa asezantsi. Ukuba iingcingo acofiweyo ngezikhonkwane, ukuba kufuneka kwimali kwenkxamleko eninzi.

Ngokuqhelekileyo, kwiitheminali aphezulu koomatshini-kwipali enye udityanisiwe umbane ngokusebenzisa ikama, kwaye ukusuka iintambo asezantsi kwenziwa ngokwamaqela. Ungakwazi ukuseta izixhobo ezininzi yogcino.

uphawu

miyalezo beesekethe babe ileyibhile umgangatho, efundwayo ukusuka phezulu ukuya ezantsi.

Imilinganiselo abekwa ku isixhobo ngokugcina ezingundoqo iparameters yayo:

• uphawu - EKF;
• namba - VA47-29;
• uphawu 'C' kwaye kayi ukuya ngokuzenzekelayo olunye-pole yangoku - 25A;
• ubonelelo ombane rated - 230/415 V;
• sivumelekile ubuninzi imisinga circuit elifutshane - 4500 A;
• 3 - class umda yangoku.

Xa lophawu, uyakwazi ukuchonga umenzi. Oomashini kuyacetyiswa ukuba bakhethe iintlobo ezaziwayo-kakuhle: Legrand, ABB, IEK, EKF, kunye nabanye.

Ncazo kwi umatshini 230/415 B kuthetha ukuba isixhobo unako ukusebenza omnye kwisigaba kunye nothungelwano ontlantlu-ntathu. Uninzi izithuthi iintambo ninakho eli khono.

Ikaliwe lwangoku - lixabiso zangoku kwi kuyo umatshini ayisayi kusebenza ixesha elide. Xa kokuba linyuke nge-13%, uya ukucima emva kweyure. Okuya uba mkhulu umsantsa ixabiso ngoku elide ezantsi emathunjini, kokukhona akhawulezayo msebenzi. Eyona njongo ephambili yale umatshini - ukuthintela nobushushu ingcingo xa umthwalo. Kubalulekile ukuba umqhubi ngoku avumelekile ukuba umatshini enkulu ihlelo, awunakho ukwenza ngolunye uhlobo.

Ixesha-yangoku uphawu "C" luthetha ukuba kuvusa off zombini iindlela zenzeka emva kahlanu Ukwandisa yangoku rated. Kufanelekile yokukhanyisa esebenza. Ukuba umatshini sifanele yokungena kule laka, kufuneka zifakwe kwi kumatshini kunye iimpawu eziphambili input "B" ku iphaneli flat. Oku kuthetha ukuba zonke ezinye iimpawu enye, oko kuya kusebenza ngokukhawuleza. Ngoko ke musa ukuba agidime aye emnyango, kwaye ziquka automatic apho. isixhobo olufanelekileyo ukheto nge iimpawu efanelekileyo inikela selectivity zinqwenelekayo nokukhubeka.

Owona mbane ngenxa yokusindwa yangoku ubonisa ixabiso layo eliphezulu apho umatshini unako ukuluvala phantsi ubuncinane kanye.

Inani izibonda

Ukuba ukhetha enye-kwipali okanye umatshini pole-mbini, kubalulekile ukuba, apho uwufake. Lokungena indlu lenjongo ephambili kufuneka ifakwe bipole. Oku kuya kuvumela ngokuthembekileyo uyeke iintambo ekhaya ngexesha ukulungiswa xa ukucima kwisigaba kunye cala. Xa wire 2 mayixhonywe umatshini kunye njengesibonda olunye kwangena endlwini. Phambi kumqhubi isiseko ukunika umatshini xingheniso kwengqondo.

On isebe ngalinye kwenethiwekhi yasekhaya elidityaniswe umatshini-kwipali enye kunye RCD.

Ukuba yokuhlala sisebenzisa wesekethe ontlantlu-ntathu kufuneka zifakwe kwi igalelo engundoqo umatshini-kwipali ezine.

Zenzekelayo single-pole: Ixabiso

Single-pole enganeno ngokuzenzekelayo phakathi kwabanye uhlelo kunye nenani elikhulu zezibonda. iimveliso zasekhaya zingathengwa ngenxa 40-50 engange., ke brand engenisiwe sele 150-200 engange. Kubalulekile ukuba ukhethe izixhobo ulwalamano umgangatho-ixabiso, kunokuba ezo zitshiphu.

Iimpazamo Ukukhetha umatshini

Ukukhetha le miyalezo, kuvumela abasebenzisi eziliqela iimpazamo.

1. Ikhokelwa ukusetyenziswa lilonke amandla endaweni kwiingcingo ukuya ukukhusela nxamnye overload. Ukufakela umatshini enamandla iintambo obuthathaka kukhokelela nobushushu yayo. Kubalulekile ukuba pick up isixhobo phezu icandelo umnqamlezo kwicingo.
2. Ivame oomatshini ezifanayo yonke imigca, nto leyo esisizathu sokuba ezinye zazo zizele kakhulu. Ukuze iziseko kufuneka bakhuselwe kwi-25 A, yaye ukukhanyisa - 16 A. I-umgca ekhokelela egaraji, inokufakwa ndandisebenzisa izixhobo ngamandla ezinamandla. Apha kuyacetyiswa ukufaka umatshini 32 A.
3. Musa ukukhetha machines ixabiso. Kulungile ukuba bathenge iimveliso yemiyinge eziziingangamsha, apho umgangatho liqinisekisiwe.

isiphelo

Ukuze ngokuchanekileyo ukhethe umatshini-kwipali olunye kufuneka siqonde ikhowudi kwi yezindlu evela ecaleni ngaphambili. iimpawu isixhobo zikhethwa kuxhomekeke kuhlobo umthwalo kunye wire cross icandelo enxibeleleneyo.
