Malunga nobunzima: Yintoni i-Udom kuHlelo

Konke malunga nenkcazo yesixhobo esikhuselweyo sokukhusela, amanqaku okufakwa kwawo kunye nolwahluko kumatshini.

Bonke abanini bamakhaya bangamatshini abaqhelekileyo onokukhusela i-ridhel yegridi yokulayisha (umzekelo, ngenxa yesekethe emfutshane) kwaye ehambelana nengxaki yakhe. Kodwa ukhuseleko olunye lwenethiwekhi oluzenzekelayo aluphumelelanga. Ukwenza oku, uninzi lwezinye izixhobo zisetyenziswa, eyona nto ithandwayo yesona sixhobo, esaziwa ngokuba yi-Uzo, ukuba yintoni ngombane - xelela kwinqaku.

Konke malunga no-Uzo.

Injongo

Umahluko ovela kumatshini

Iindawo zokufaka

Kutheni kufuneka u-Uzo.

Ke, yintoni i-UDO kumbane? Isifinyezo sigqityiwe njengesixhobo "sokukhusela ukungenisa", kunye neenjineli kunye neengcali zikhetha ukuyibiza ngokuba yindawo yokutshintsha eyahlukileyo. Esi sixhobo senzelwe ukulandela umkhondo wangoku ukuvuza ukusuka kumonakalo kwizixhobo zombane kunye nezixhobo zombane.

Umatshini we-Lagrand eyahlukileyo

Kwiimeko eziqhelekileyo, okwangoku, ngokuthetha ngokuzinzileyo, ukuqukuqela ukusuka kumqolo wokungathathi hlangothi (ukusuka "kwinqanaba" ukuya kwi-"yero") ngesixhobo esiqhutywa (umbane). Ukuba, yithi, ngenxa yomonakalo kwibala elingenanto, izindlu ze-wiring okanye intsimbi yezixhobo zombane zasekhaya (umzekelo, umatshini wokuhlamba) uvela apho i-versing uqhubeke ukuqhubeka kwi " Zero ", kodwa ngokoqobo emhlabeni. Oku kuyenzeka, ngelishwa, rhoqo - umntu wachukumisa ucingo kwaye wafumana iflegi yangoku - okwangoku ngomzimba wakhe wangena emhlabeni. Umtyholi wesekethe akasayi kuqaphela lo mthwalo mncinci kwaye akasebenzi, kwaye ukubetha kwangoku kunokutyeka. Apha ukukhusela ukuvuza okunjalo kwaye kuyimfuneko kwi-UDO.

Ezi zixhobo zibaluleke kakhulu ukukhusela igridi yamandla kwiindawo zengozi eyandayo, umzekelo, kumasango emanzi, naphi na apho kudibana khona nomhlaba okuphakamileyo. Izixhobo ezikhuselweyo ezikhutshelweyo zifakwe kwimigca ye-wiring yombane yegumbi lokuhlambela kunye nenethiwekhi yesitalato, umzekelo, elizweni.

I-Uzo i-Uzo ephezulu ye-25 A, ukuvuza okwangoku

Umahluko we-Abb DSH941r umatshini uphakamisa i-10 a, ukuvuza i-30 ma

I-Uzo i-Uzo ephezulu ye-32 A, Ukuvuza ngoku-30 ​​ma

Ukuthelekisa: ukwaphulwa kwesekethe enye. Umahluko obonakalayo: I-wire enye kuphela kwigalelo kunye nemveliso ixhunyiwe.

Umahluko ovela kumatshini

Ke, yintoni umahluko phakathi kwe-RCD evela kumatshini kumbane? Ngaphandle kokungena kwiinkcukacha zoyilo-umatshini usebenza kwimidlalo enkulu kunowona mthwalo uphezulu kwinethiwekhi (umzekelo, kukho i-Autotive 10, 25, kwaye ezona modeli zithandwayo zikhulelweyo zibangelwa kukuvuza okwangoku ye-30 milliaamper (M). Oko kukuthi, okwangoku kufunyenwe phantse i-1 000 ka-10,000. Isantya sokukhusela simalunga ne-100 milliseconds (0.1 s). Ngexesha elifutshane lokuvezwa, umntu akasayi kuva.

I-ABB eyahlukileyo ye-ABB.

Ngokwahlukileyo koko, masithi, isixhobo esikhukhuselweyo sokukhusela sifuna ukulungiswa rhoqo kothintelo kubaphulaphuli. Nangona kunjalo, akukho nto inzima kuyo - umniniyo kufuneka acinezele iqhosha kwizindlu.

Kwaye kutheni kwaye kutheni ifake isekethe

Esi sixhobo sinokufakwa njengamasebe ahlukeneyo egridi yamandla ekukhonza iindawo eziyingozi (igumbi lokuhlambela, igaraji, eyadini) kunye nenethiwekhi yendlu yendlu. Kumazwe aseNtshona, ngokubanzi asikokwesiko ukuba baqondwe ngokukhuselwa, banokubekwa phantse kuwo onke amaqela esikolo.

Kwimimandla emanzi kunye nezitrato

Ukukhusela kumonakalo kwimanzi emanzi kunye noluhlaza, kwaye inethiwekhi yesitalato isebenzisa i-Uzo ngo-30 okanye (kancinci) i-10 ma. Ezi zixhobo zibonelela ngenqanaba lokhuseleko olufanelekileyo, kodwa zinovelwano kakhulu, kwaye ukuba zifakwe kuyo yonke inethiwekhi yendlu, iimpendulo zobuxoki zinokwenzeka.

Inethiwekhi yonke yendlu

Ukutshintshela kwi-100 ma (nangaphezulu kwe-300 ma) ayikukhululekanga-umntu uya kuziva evuthuza okwangoku, kodwa engenabungozi- kodwa akanabungozi. Zifakwe kwinethiwekhi yendlu njengezikhuselo ezongezelelweyo, kunye nokukhusela emlilweni. Ezi zixhobo ziyakwazi ukubamba ukuvuza okuvela kwiindawo ezifihlakeleyo zeewiri. Umzekelo, kwenye indawo eludongeni okanye kwi-rosette yefanitshala, kwakungekho drad ukuba ihlale kwi-wire okanye ibuthathaka iikrikhi zonxibelelwano zabafowunelwa. Ucingo okanye isokisi iqala ukufudumala. Ukuba amavuvu asingabi ngokwaneleyo (i-rusrey encinci), ukwaphula umthetho wesiphaluka akusebenzi. Ngeemeko ezinjalo, utshintsho olukhethekileyo lokutshintsha luyafuneka ngempendulo yangoku i-100 okanye engama-300 ma.

I-ABB eyahlukileyo ye-ABB.

Iindawo zokufaka

Ukufakelwa kufakelwa kufakwa kwi-din-rail yololiwe din-uloliwe. Inkqubo yokuqhagamshela isixhobo esikhutshelweyo esikhuselweyo kwaye umphulisi wesekethe unokubakho inokwenzeka ukuba idideke i-factor engenamava.

Okubaluleke ngakumbi, qhagamshela inkcazo eyintloko yezi zixhobo. Kubalulekile ukuba i-Uzo ibe yenzelwe ukugqithisa kwangoku kwamandla afanayo okanye ngaphezulu njengokutshintsha. Umzekelo, ukuba unamatshini ozenzekelayo, emva koko i-RCD nayo kufuneka ibalwe ukuba ubuncinci i-10 A. kunye nemisebenzi, kuyacetyiswa ukuba uthathe isixhobo esenzelwe inyathelo elinamandla langoku elinye apha ngasentla. Oko kukuthi, kwisibini esinomatshini we-10 A, kuthatha i-16 A, ye-16 kwaye uthathe i-25 A, njl.njl.

Iintlobo ngeentlobo ze-Uzo ziimodeli ezinokukhuselwa ngokwakhelwe kwi-voltagety igqitha. Ukuba endaweni ye-220 kwinethiwekhi iza kuqala "kwi" 260-270 v, emva koko kunye nezixhobo zendlu ziya kuba nengxaki enkulu. Ukukhusela ngokuchasene noko kwaye kusebenza ezo zixhobo.

Umatshini weSchneider yombane

Abaphulaphuli besekethe kwaye u-Uzo unokudityaniswa kwisixhobo esinye, esibizwa ngokuba yindawo eyahlukileyo yesekethe (i-avdt okanye i-dissavtomatom). Loluphi ukhetho olufanelekileyo ukuba lusetyenziswe (izixhobo ezimbini ezixhubeneyo okanye enye), ixhomekeke kwiskimu sokudibanisa zonke imithwalo yenethiwekhi, kodwa enyanisweni ithi, imeko yokungcamla.
