Umshini Unipolar: apharathasi, izici lobuchwepheshe kanye izici uxhumano

Circuit full - a idivayisi usuke, le conductive evumelekile kagesi futhi icishe amandla okweqa ukubaluleka bokuzisholo. Isetshenziselwa isivikelo sindisa izifunda kagesi. Single-pole othomathikhi ivikela wire eyodwa kuphela.

Idivayisi futhi Umgomo we operation

I izici eziyinhloko we inkinobho kukhona ijubane okuzisholo futhi ukuvala shaqa. umshini Unipolar usebenza ngezindlela ezimbili: ezishisayo kanye kagesi uhambo iyunithi. Eyokuqala ikhubaza wesifunda uma kwenzeka i umthwalo anda of action isikhathi eside, kanti eyesibili - kweso, lapho isekhethi.

kudivayisi Thermal ukuvikelwa ipuleti bimetal. Lapho zamanje sidlula ke ngaphezu esiphezulu, kancane kancane heats futhi amajika, ukusunduza isigwedlo, umshini livaleke-off. Emva lwaluyophola ipuleti emuva endaweni, kanye inkinobho uyaphinda isilungele ukusebenza. Ukuze angene operation, ixhume ngesandla.

Idivayisi kagesi siqukethe ikhoyili elise ngaphakathi ekujuleni kwenhliziyo. Lapho edabula zamanje isekhethi kwenzeka emazombezombe kagesi mandrel eveza zasendle, ezikhona ikhubaza umshini. Kulokhu oxhumana amandla zivulwa, uyeke yokuvuselela wesifunda. Njengoba udlule zamanje esikhulu, i arc. It uwela ekamelweni arc, lapho parallel izingcwecwe zensimbi ezilula. Ngosizo lwabo, le arc ibhidliza futhi disintegrates.

Umshini nawo usebenzise njengendlela inkinobho ngokushintshanisa imanuwali ukulawula isigwedlo.

Ukusetshenziswa olulodwa-pole wesifunda full

Wiring efulethini ihlukane amaqembu amaningana. Ixhuma umshini owodwa isigxobo ikhiqizwa igebe umqhubi isigaba. It ibekwe phezu Din wesitimela, futhi engenhla amandla JIG wire yayo ifakwe. wire Sivikelwe ixhunywe ngocingo aphansi. Uma izintambo kuthiwa sicindezelwe ngezikulufo, kumele some ngomzamo omncane.

Ngokuvamile, ezikhumulweni engenhla imishini olulodwa-pole uxhumeke kwi-amandla supply ngokusebenzisa ikamu, futhi kusukela wiring aphansi kwenziwa emaqenjini. Ungasetha kunokokusekela amaningi.

wokugubha

Circuit amadlambi unelebuli standard, okuyinto ukufunda kusuka phezulu kuya phansi.

Amanani abekwa ku-ithuluzi Ezezindlu imingcele yayo eziyisisekelo:

• lokuhweba - EKF;
• inombolo ye-serial - VA47-29;
• isici "C" futhi wamanje ukalwe kuya othomathikhi olulodwa-pole - 25a;
• ukalwe supply voltage - 230/415 V;
• ovumelekile esiphezulu off iDemo imisinga wesifunda ngaleso - 4500 A;
• 3 - zamanje umkhawulo ekilasini.

Ngu sha, ungakwazi ukuhlonza umenzi. Machines kungcono ongakhetha kuzo brand owaziwa: Legrand, ABB, IEK, EKF, nabanye.

Igama-ncazo emshinini 230/415 B sisho ukuthi idivayisi ungasebenza owodwa esigabeni futhi ezintathu okhombisa amanethiwekhi. Iningi izimoto e wiring lakho lomndeni kudingeka leli khono.

Kulinganiswe ngo wamanje - ukubaluleka lamanje lapho umshini ngeke isebenze isikhathi eside. Lapho-ke luyanda 13%, kube izovala ngemuva kwehora. Kukhula ukubaluleka wamanje eside ogelezayo, ngokushesha lo msebenzi. Injongo eyinhloko umshini - ukuvimbela okweqile ezintanjeni zikagesi ezinde ezingaphansi uma kuxhunywa umthwalo. Kubalulekile ukuthi sivumelekile umqhubi zamanje lokhulu ihlelo umshini, hhayi okuphambene nalokho.

isici Isikhathi-samanje "C" kusho ukuthi nokucupha off kokubili izindlela okuyokwenzeka ngemva kahlanu ukwandisa wamanje esinesilinganiso. Kuyinto efanelekile okukhanyisa zikagesi kakhulu. Uma umshini kuwufanele umnyango lesi sici, kufanele efakwe emshinini ne isici eyinhloko okokufaka "B" kwephaneli flat. Lokhu kusho ukuthi bonke abanye izici ezifanayo uzosebenza ngokushesha. Khona-ke akudingeki ukusebenzisa emnyango, futhi zihlanganisa othomathikhi lapho. Proper Ukukhetha idivayisi ne isici efanelekayo inikeza selectivity ofiselekayo ka ezithothene.

Eliphelele elivumelekile ezithothene zamanje kubonisa ukubaluleka walo omkhulu lapho umshini uyakwazi shaqa okungenani kanye.

Inombolo izigxobo

Uma ukhetha owodwa isigxobo noma umshini ezimbili pole, kubalulekile, lapho ukuyifaka. Lapho bengena efulethini iphaneli main kufanele afakwe bipole. Lokhu kuzovumela thembeke unqamule wiring ekhaya ngesikhathi elungisa lapho ukucisha isigaba nge hlangothi. Lapho wire 2 kungenziwa agibele amahhashi mshini isigxobo esisodwa busuka endlini. Ephambi kwezinduna umqhubi isisekelo ukunikeza umshini ezethula okuguquguqukayo.

On legatsha ngamunye inethiwekhi ekhaya ixhunyiwe umshini owodwa pole ne RCD.

Uma indawo lusekelwa ngamandla wesifunda ezintathu okhombisa kufanele afakwe ngesikhathi okokufaka main amane isigxobo umshini.

Okuzenzakalelayo olulodwa-pole: Intengo

Single-pole othomathikhi eshibhile phakathi kwabanye uhlelo ngenombolo enkulu izingongolo. imikhiqizo Domestic zingathengwa for ruble 40-50., Futhi brand amazwe kakade ruble 150-200. Kubalulekile ukukhetha amadivayisi ubudlelwane izinga-intengo, kunokusebenzisa lezi ezizodinga ukuba ishibhile.

Amaphutha e Ukukhetha umshini

Ukukhetha amadlambi, vumela abasebenzisi eziningi amaphutha.

1. Ukuqondiswa NguNkulunkulu Imininingwane amandla ukusetshenziswa esikhundleni sezintambo ukuze azivikele sindisa. Ukufaka umshini elinamandla wiring ababuthakathaka kuholela okweqile yayo. Kubalulekile sithathe idivayisi phezu Ingxenye evundlile wire.
2. Ngokuvamile ukusetha imishini efanayo kuzo zonke imigqa, yingakho nje abanye babo zigcwale ngokweqile. Ukuze enethiwekhi kudingeka uvikelwe ngaso 25, futhi ukukhanyisa - 16 A. umugqa okuholela egalaji, kungaba kakhulu ezithwele ngamathuluzi anamandla amandla. Lapha kungcono ukufaka umshini at 32 A.
3. Musa ukukhetha imishini ngentengo. Kungcono ukuthenga imikhiqizo lemikhiqizo ezidumile, lapho izinga kuqinisekisiwe.

isiphetho

Ukuze kahle ukhethe umshini owodwa isigxobo kumele baqonde ikhodi izindlu kusukela ohlangothini front. idivayisi izici ezikhethiwe kuye ngohlobo axhunyiwe umthwalo futhi ngocingo cross kwesigaba.
