Khetha iiSekethe zeSekethe kunye ne-Uzo ngokupha: Iiparamitha ezi-5 ezibalulekileyo

Ukuvalwa ngokusenzekelayo, ukuvalwa okuzenzekelayo, ukukhuselwa okuvaliweyo kunye nezinye iindlela ezifuna ukuqwalaselwa xa ukhetha.

Ukukhuselwa kombane kunye nemililo ikakhulu kuxhomekeka ekusebenzeni kwezixhobo ezikhutshiwe ngexesha elifanelekileyo. Kwindlela yokukhetha ezi zixhobo ukukhetha, usixelele kwinqaku.

I-1 udo yamaqela ahlukeneyo eenethiwekhi zombane

Zonke switches ezizenzekelayo zisetyenziselwa ukukhubaza umgca ngexesha lokugqibela okanye isiphaluka esifutshane. Kwisahluko esilula sokhuseleko, ukwaphula umthetho omnye wesekethe kusetyenziswa, onoxanduva lokulungisa inethiwekhi yekhaya. Kodwa olu khetho lufanelekile ngaphandle kwendlu encinci yegadi. I-cottage apho kukho izixhobo ezahlukeneyo zeshishini, kuyacetyiswa ukwahlula abasebenzisi kumaqela aliqela. Oku kunokuba, umzekelo, amaqela amathathu: izibane, iziseko, iziseko kunye nezixhobo zamandla; Kwiqela elahlukileyo, ngamanye amaxesha kukho inethiwekhi yesitalato (kubandakanya igaraji kunye neworkshop).

I-2 ye-tok yamandla

Iqela ngalinye lixhotyisiwe yi-subnet yayo, elinikezelwa ngokutshintsha ngokuzenzekelayo kwi-OKUSETYENZISIWEYO KWISITHUBA. Ungawafumana njani amandla akhoyo kwikhonkco? Ukufumanisa amandla langoku kudle umthwalo umthwalo wahlulwa ngokwakhiwa kwi-voltage yenethiwekhi yombane (220 v). Ukuba, umzekelo, amandla apheleleyo kuzo zonke izixhobo yi-1 kW, ke okwangoku kwinethiwekhi iya kuba malunga ne-5 A. Umphunga wesekethe oLungileyo kufuneka ulingane nenyathelo lexabiso lexabiso elifunyenweyo. Ekusebenzeni, umzekelo, kwinkqubo yokukhalatha, i-wiring kunye nezixhobo, ukubalwa okwangoku kwi-10 A, izixhobo zamandla - 25 A, i-Azenzekelayo kufuneka ibalwe kwimigaqo ye-10, 16 kunye ne-25 A.

I-3 yokuvala ngokuzenzekelayo

LUYINTONI IXESHA LOKUGQIBELA? Le paramitha iphawula isantya seso sixhobo siye kwangoku, ixabiso lalidlula ixabiso elichanekileyo. Kubomi bemihla ngemihla, ukutshintshwa okuzenzekelayo kweentlobo B, C kunye D, ixesha elininzi - uphawu lwangoku. Uhlobo Blers beseketheki kwi-B ngokugqithileyo kwixabiso elichanekileyo lamaxesha ama-3-5, uhlobo c ngamaxesha angama-5 ukuya kweli-7, kwaye uhlobo d ngamaxesha ayi-10 ukuya kweli-15. Iindidi ze-B no-C zihlala zisetyenziswa, nangona kunjalo, kwinethiwekhi ezinxulumene nazo iimoto zombane ezinamandla, kungcono ukuthenga i-D. Ukophula umthetho wesekethe.

UAlexander Bespalov, Eaton Imveliso yeMveliso

Ungawahlula umphunga wesekethe ophezulu wezinto ezininzi. Nika ingqalelo kumgangatho wezindlu kunye nobunzima bemveliso-Iphaneli yangaphambili kufuneka ibe yi-monolithic, ifanelekile ukuba izahlulo zincinci, kwaye esi sixhobo ngokwaso asilulanga kakhulu (xa sithelekiswa ne-analouves). Isisindo esincinci sinokuthetha ukuba umenzi ugcinwe kwizinto kunye neenkcukacha. Kwi-AV ekumgangatho ophezulu we-AV yentambo kunye nezinye iinxalenye zangoku zenziwa ngobhedu, oluvumela ukuba ifowuni ifudumeze kancinci (kwaye igqithise). Ezo zixhobo zinokhetho oluninzi, umzekelo, zixhotywe ngeentambo zokukhusela iziqwengana zentambo kwaye zinesalathiso sombala wesikhundla soqhakamshelwano.

I-4 Ukukhusela ukukhusela

Ukongeza kubaphulaphuli besekethe, umnini we-cottage uya kufuna ukutshintshela okwahlukileyo (okwaziwa njengezixhobo zokuHlanganisa, zilawulwa ngokwahlukileyo, okanye u-Uzo), owona msebenzi ukhusela ngokuchasene nokuvalwa komhlaba. I-UDO ikhusela abantu kwi-Wire yoMbane xa ichukunyiswe kwi-wire ye-wire okanye i-stare yentsimbi, ebangelwa yi-voltage esebenzayo ngenxa yokungasebenzi kakuhle. Imijikelezo yesekethe esemhlabeni zinokukhokelela kwimililo, oko kukuthi, i-RCD ikwathintela umlilo.

Ukutshintsha komgangatho: Ukucima i-Grille (i-9 plates); 2 - I-SEEL Clemp; 3 - Akukho zikhethini zikhuselayo; I-4-Ikhamera yokuphelisa

Ukutshintshela komgangatho: 1-I-qwetu lemigangatho; 2-Ingqumbo yobhedu; 3 -Ukucima iGrille (iipleyiti eziyi-13); Igumbi eli-4 -Ukususa igumbi; Ukuhlaselwa oku-5 kweSilivere

I-RCO kufuneka ixhotywe ngenethiwekhi apho amathuba othuso lombane likhulu ngenxa yomonakalo wokufakelwa kombane okanye i-wiring. Ezi ziindawo zokuhlambela kunye nawo onke amagumbi emanzi, kunye nenethiwekhi yesitalato. Khetha i-Uzo kuxhomekeke kwi-leakied okwangoku (ilinganiswe kwi-milliamperes-ma), incinci ixabiso, ukuphakamisa imvakalelo yesixhobo. Kubomi bemihla ngemihla, u-Udos uhlala usebenzisa ukuvuza kwe-10, 30 ne-100 ma. Ezona zinto zinobuthathaka (i-10 okanye i-10 okanye 30 ma) zifakwe kumakhonkco apho onokhuseleko oluphezulu luyafuneka, umzekelo egumbini lokuhlambela. I-Uzos engacacanga (i-100 ma) ifakwe kumakhonkco, apho inamandla (2-3 kw nangaphezulu)) kunye nezixhobo ezifanayo: Xa zivuliwe, u-Uzos obuthathaka uya kuguquka ngobuxoki. Kwikhaka, u-Uzo jikelele ufakwe emva kobume be-Eleclight kwiseti yabaphuli besekethe ngokuzenzekelayo kwimijikelezo nganye yesekethe eya kuyikhusela i-RCm ephuma kwisekethe emfutshane. I-Uzo kufuneka ifakwe kuphela ngokudibeneyo kunye nokutshintsha ngokuzenzekelayo. Ngenye indlela, ungasebenzisa abaphulaphuli besekethe (i-AVDT, okanye izabalasele imisebenzi ye-RCD kunye ne-Azenzekelayo.

Kwizixhobo ezinokuthenjwa, izinto ezixabisa ngakumbi zisetyenziswa - umzekelo, uhlaselo lwesilivere kunxibelelwano.
