Konke mayelana nokuchazwa kwensiza evikelekile yokuvala, izici zokufakwa kwalo nokwehluka okuvela emshinini.
Bonke abanini khaya bayimishini evamile evikela ifulethi likagesi ngegridi eligcwele kakhulu (ngokwesibonelo, ngenxa yesifunda esifushane) futhi lihlotshaniswa nenkinga yakhe. Kepha ukushintshwa kokuphepha kwenethiwekhi okuzenzakalelayo akufinyeleli. Ukuze wenze lokhu, kusetshenziswa amanye amadivaysi amaningi, athandwa kakhulu yilokho namuhla idivaysi, eyaziwa ngokuthi i-UZO, ukuthi kuyini ku-electronic - sho ku-athikili.
Konke nge-UZO.
OkuhlosiweUmehluko emshinini
Izindawo zokufaka
Kungani udinga i-UZO.
Ngakho-ke, yini i-UDO e-Electric? Lesi sifinyezo sihlotshiswe njenge- "divaysi yokuvikela incithakalo", futhi onjiniyela nochwepheshe bakhetha ukuyibiza ngokuthi i-switch ehlukile. Idivayisi yakhelwe ukulandelela ukuvuza kwamanje okuvela ekulimaleni kuya kwimishini yokulingisa kanye nemishini kagesi.
Umshini Wokuhlukanisa Umshini
Ezimweni ezijwayelekile, okukhuluma kalula, okulula, ukugeleza kusuka kulayini kumqhubi we-izingalo (esigabeni "kuya ku-" zero ") kudivayisi eqhutshwa (ngokwesibonelo, i-bulb noma motor kagesi). Uma, yithi, ngenxa yomonakalo ongenalutho, izindlu ezinamaphiko noma zensimbi yemishini yasendlini (ngokwesibonelo, umshini wokuwasha) uphenduke amandla, isimo kungenzeka lapho kuqala khona lapho kuqala khona ukuthi okwamanje kufika lapho kufika khona lapho kufinyelela khona " zero ", kodwa ngokoqobo emhlabathini. Lokhu kwenzeka, ngeshwa, imvamisa - umuntu athinte ucingo futhi athola ukushaya kwawo okukhona njengamanje - okwenzeka emzimbeni wakhe waya emhlabathini. Umfutho wesifunda ngeke aqaphele lo mthwalo omncane futhi akasebenzi, futhi ukushaywa kwamanje kungabulala. Lapha ukuze uvikele ekuvuzeni okunjalo futhi kuyadingeka ku-UDO.
Amadivayisi abaluleke kakhulu ukuvikela igridi yamandla ezindaweni zengozi ekhuphukayo, ngokwesibonelo, emagcekeni amanzi, kanye nakuyo yonke indawo lapho kukhona khona nomswakama womhlaba kanye nomswakama ophezulu. Amadivaysi avikelwe ngokuvikeleka afakiwe kwimigqa ye-wiring kagesi yezindlu zangasese kanye nenethiwekhi yasemgwaqweni, ngokwesibonelo, ezweni.
UZO Maximume reast 22 A, Ukuvuza Kwamanje 30 MA
I-ABB DSH941R Machine Machine Passand Yamanje 10 A, Ukuvuza Kwamanje 30 Ma
Indima enkulu yendima yamanje 32 A, Ukuvuza Kwamanje 30 Ma
Ukuqhathanisa: I-One-Post Breaker Breaker. Umehluko obonakalayo: ucingo olulodwa kuphela kokufakwayo nokukhipha kuxhunyiwe.
Umehluko emshinini
Ngakho-ke, umehluko muni phakathi kwe-RCD kusuka emshinini ku-Electric? Ngaphandle kokuya imininingwane yokwakheka - umshini usebenza kuma-currunts mkhulu kunomthwalo omkhulu kunethiwekhi (ngokwesibonelo, kukhona ama-automata 10, 16, 25 AMPS), futhi amamodeli adumile avale kakhulu avuthayo, futhi amamodeli avaliwe kakhulu wokuvimbela ka-30 milliamper (ma). Okungukuthi, okwamanje kutholakala cishe izikhathi eziyi-1 000 zibuthakathaka. Ijubane lokuvikelwa licishe libe ngama-milliseconds (0.1 s). Ngomzuzu omfushane ovezwa, umuntu ngeke azwe ngisho nokushaywa.
Umshini ohlukile we-automatic abb.
Ngokuphambene nalokho, ake sithi, idivaysi evikelekile yokuvikelwa idinga ukulungiswa okuvinjelwe okujwayelekile kusuka kubaphuluki besekeli. Kodwa-ke, akukho lutho olunzima kulo - umnikazi kufanele acindezele inkinobho ezindlini.
Kuphi futhi kungani ubeka umjikelezo
Idivayisi ingafakwa njengamagatsha ahlukile wegridi yamandla esebenza ngokukhethekile izindawo eziyingozi (zokugezela, i-sauna, egalaji, inethiwekhi) nayo yonke inethiwekhi yendlu. Emazweni aseNtshonalanga, imvamisa kungejwayelekile ukuthi akunjalo ngokwesiko ukuqondakala ukuvikela, kungafakwa cishe kuwo wonke amaqembu ezisekeli.Ngezindawo ezimanzi kanye nemigwaqo
Ukuvikela ukulimala kwalamanje emakamelweni amanzi nasekubhukeni, futhi inethiwekhi yasemgwaqweni isebenzisa i-UZO nge-30 noma ngaphezulu) 10 ma. Lawa madivayisi ahlinzeka ngezinga lokuphepha elinethezekile, kepha azwela kakhulu, futhi uma efakwa kuyo yonke inethiwekhi yendlu, izimpendulo zamanga zingavela.
Inethiwekhi yonke yendlu
Ishintsha nge-100 MA (futhi ezingaphezu kuka-300 ma) azithokozeki - umuntu uzozwa ukushaya kwamanje, kepha angahlupheki - kepha abuzwe kangako. Zifakwa kwinethiwekhi yendlu njengokuvikelwa okwengeziwe, kanye nokuvikelwa komlilo. Lawa madivayisi ayakwazi ukubamba ukuvuza ezindaweni ezifihliwe ze-wiring. Isibonelo, endaweni ethile odongeni noma e-rosette yefenisha, kwakungekho dod ukuze aphile ngocingo noma abuthaka iziqeshana zokuxhumana zoxhumana nabo. Ucingo noma isekhokele liqala ukufudumala. Uma ukuvuza kungabi nzima ngokwanele (imijikelezo yokujikeleza emfushane engaphansi), i-circuit Breaker ayisebenzi. Kumacala anjalo, kudingeka switch ekhethekile ngokuhlukile ngempendulo yamanje yamanje 100 noma 300 ma.
Umshini ohlukile we-automatic abb.
Izindawo zokufaka
Ukufakwa kuvame ukufakwa kuhlobo lwe-DIN-LIDTY DIN-Rail. Inqubo yokuxhumanisa idivaysi evikelekile yokuvala futhi i-Breaker yesekethe kungaba yinoma iyiphi (into esemqoka ukuthi umdwebo wokuxhuma ulungile), kodwa kungenzeka ukuthi ube phambili, futhi ngemuva kwaso kulula ngayo, futhi mancane amathuba okuthi udideke isifakeli esingenalwazi.
Okubaluleke kakhulu, ukuxhuma imininingwane yokuqokwa kwalawa madivayisi. Kubalulekile ukuthi i-UZO yenzelwe ukudlula kwamanje kwamandla afanayo noma ngaphezulu njengokushintsha. Isibonelo, uma unomshini ozenzakalelayo we-10, khona-ke i-RCD kumele futhi ibalwe ngentengo yamanje okungenani ayi-10 A. futhi ngemisebenzi, kunconywa ukuthatha idivaysi eyenzelwe isinyathelo esinamandla samanje esinamandla ngaphezulu. Lokho wukuthi, ngomshini onomshini ongu-10 a, kuthatha i-16 a, ngo-16 futhi uthathe ama-25 a, njll.
Izinhlobonhlobo ze-UZO ezithokozisayo amamodeli anokuvikelwa okwakhelwe ngaphakathi ekulweni kwamagesi. Uma esikhundleni sakwa-220 kunethiwekhi kuzoqala "ukudlulisa" 260-270 v, bese kuthi ngemishini yendlu kuzoba nenkinga enkulu. Ukuvikela emaqenjini anjalo futhi kusebenza amacebo anjalo.
Umshini wokuhlukanisa umzimba kaSchneider
Abaphukileyo besekethe kanye ne-UZO bangahlanganiswa bangene kudivayisi eyodwa, ebizwa ngokuthi yi-Differial Precial Breaker yamanje (i-AVDT noma digavtomamom). Yikuphi ukukhetha okulula ukusetshenziswa (amadivaysi amabili axhunyiwe ngokulandelana noma okukodwa), kuya ngesikimu sokuxhuma yonke imithwalo yenethiwekhi, kodwa empeleni, njengoba besho, icala lokunambitha.
