Udibaniso lwe imitha yombane isigaba ezintathu

Imitha efunekayo kuqala inkampani amandla, kwaye umboleki unoxanduva ukufaka kuyo indlu endlwini, egaraji okanye cottage. Le ezindlini zicwangciswa isixhobo engundoqo single-isigaba. Ohlanganisa counter isigaba uqobo oluqhutywa kumakhaya.

iimitha abaninzi esifakelwa ixesha elide yaye zifuna indawo. Izizathu eziphambili zale zimi ngolu hlobo lulandelayo:

• ekupheleni kobomi;
• ukulahleka ukuchaneka yokulinganisa (ngezantsi kwiklasi yesibini);
• imfuneko ukufaka isixhobo-rate multi.

Faka isimangalo esitsha kungenziwa ngoncedo yeengcali okanye wena. Akukho bunzima ezikhethekileyo, kodwa imigaqo kufuneka ilandelwe.

Yintoni counter ukukhetha?

Ngaphambili bakhiwe uhlobo zokubala mechanical (induction). kokukhululwa kwabo usaqhubeka, ufakelo amandla ziinkampani amandla. Endaweni yokuba uyilo ezindala ziye izixhobo elektroniki digital. Zombini izinketho ngokufanayo benze umsebenzi wabo, kodwa okubi ukumelana inyathelo ngomatshini lobushushu eliphantsi. Kubalulekile ukuba esi sixhobo yabanjwa ngomhla eklasini ekuchanekeni, apho kufuneka kungabikho ngaphantsi kuneyesibini.

Indlela ukudibanisa imitha ontlantlu-ntathu?

Udibaniso lwe imitha yombane isigaba emithathu evela kwi-mbane ahambelanayo.

Yena ezifunekayo kwisakhiwo, baxhotyiswa kunye boilers, izixhobo umatshini, izixhobo amandla ombane kunye nezinye. Emnyango ukucwangcisa cabinet ulawulo kunye izixhobo zokhuselo kwi enye ontlantlu-ntathu. Igalelo kuthungelwano yangaphandle iqulathe umphakathi 4 okanye 5, usebenzisa 3 ukuwaphatha lwangoku, zero yaye umqhubi nozinzo. Isisekelo uyakwazi uzakubekwa ngokwahlukileyo.

Uxhulumaniso lusenziwa kwinethiwekhi counter-phase ngqo okanye ukuthoba ombane kunye nakumaziko aguqula amandla yangoku. Bona efakwe kwi kumandla zeesekethe xa amandla yesekethe iphezulu ngaphezu koko kwefowuni. A uxhulumaniso ngqo wenziwa iingcingo ezintathu conductive L1 womnatha, L2, L3 kunye umqhubi cala N (Fig. Ngezantsi). Iziphumo zolu lesigaba kunye zero kwi iiclamps zikhonjiswe njengoko L1 ', L2', L3 'kunye N'. terminal output ngalinye elahliweyo kufuphi ngaphambili.

Ngoku yayivelisa iintlobo imifuziselo, inani kwiitheminali kwaye inokuba nezikmu ezininzi nezahlukeneyo. Umzekelo, kunye ukugcina 1 yenzelwa phezu kwicala kwigalelo le uqhagamshelwano counter ontlantlu-ntathu "Mercury 233", 4, 7, 10. Ngoko kuyimfuneko ukuba banikele ingqalelo inkqubo echazwe kwi ID isixhobo. Ohlanganisa counter isigaba "Energomera" kwenziwa ngendlela eqhelekileyo echazwe apha ngasentla.

Okubalulekileyo! ukusetyenziswa Amandla ebalulwe kwisiqinisekiso ngenxa ekhawuntarini. Ukuba kuyedlulwa, oku kungabangela ekungaphumelelini isixhobo, nkqu lomlilo wakhe. Ukukhetha sokubala efanelekileyo kufuneka kuqala abale izixhobo amandla ekudleni iyonke. is he taken enovimba, ukuba ikamva kulindeleke ukuba ukwandisa umthwalo.

Iimpawu kwisigaba ezintathu-uqhagamshelo imitha

Iimpawu ze-nkqubo imi ngolu hlobo lulandelayo:

1. Kufuneka pre-ukuthenga zonke izincedisi ukuze ukufakwa: swi, imitha yombane, oomatshini, RCD.
2. Ukuze kuqinisekiswe isixhobo accounting ngenkonzo phambi kokuba ekufuneka ukufaka umatshini ontlantlu-ntathu.
3. Cable umbane wangaphandle kuqala eqhagamshelwe automaton igalelo.
4. Kwimatshini izigaba ezithathu oxhulumene kwi counter, yaye emva kwakhe, ngenxa RCD - umthwalo.
5. Xa kufuneka ibe kwisigaba edidekile kunye nezinikezeli cala ohlanganisa intambo.
6. Ukuyincula isixhobo inxibelelene ukuya RCD.

NgokoMthetho uqhagamshelo imitha

Ngenxa yokuba unit of accounting ngokuyintloko luncedo ukuba inkampani amandla, yonke imisebenzi enxulumene uxhulumaniso, wenziwe inxaxheba abameli balo. Ufakelo kungenziwa ngezandla zakhe, kodwa kwinqanaba lokugqibela kuyimfuneko ukuba esisebenza. Emsebenzini kuyimfuneko ukukhumbula oku kulandelayo:

1. Ayanda ezinxulumene imithetho engqongqo kunye nemigaqo ezifuna inkampani yolawulo ukuthobela.
2. Kuyimfuneko ngophawu umenzi kunye nenkampani eliluncedo le, umboleki ukutshintsha iintambo. Emva uphawu imfuneko ukufumana izandla zakho phezu isiqinisekiso ukwamkeleka.

Ukuba imitha ifakelwe ngaphandle amandla umbutho, kuya kuthathelwa ngqalelo isixhobo yolawulo. Kuya kuba eqhelekileyo sombane isixhobo, RCD okanye wesekethe.

Ohlanganisa counter isigaba "Mercury 230"

Amaxesha amaninzi ubeka counter "Mercury" iphawulwa ezahlukeneyo imisebenzi ezahlukeneyo. Oku kulinganisa amandla yovukelo kumacala omabini. Izilungiso ikuvumela ukubala amandla lweerhafu abangatshatanga ezininzi, kunye nolwazi lilindelwe umsebenzi elide ixesha. iimpawu eziphambili yesibali:

• ithuba kwefowuni elinokukhethwa amandla ubuninzi kunye yangoku kwimo kwakunye neklasi nezichanekileyo;
• akhawunti ukuhamba amandla ibhidi;
• ubukho iinkuni siganeko kunye nokusebenza umgangatho amandla ;
• Ithuba lokuphumla phakathi nokuqinisekiswa yiminyaka-10;
• ubomi inkonzo - ukuya kutsho kwiminyaka engama-30;
• ukufumaneka lwenjongano kunye modem.

uqhagamshelo Electrical

Ohlanganisa counter isigaba "Mercury 230", nabo bonke abanye zingenziwa ngqo kwinethiwekhi ngokusebenzisa ucingo okanye current, ukuba namandla ngokwaneleyo. To connect wahlala apho ezinjengeetheminali 8. 1, 3, 5 ezinjengeetheminali zisetyenziswa ukudibanisa izigaba ezithathu zolimo. zisoloko umatshini induction, ezisabela-mbane ombane ngamandla. Kuba umthwalo nganye kufuneka wenziwe 2, 4, 6. Xa iiclamps yesixhenxe neyesibhozo uxhulumanisa, ngokulandelelana, igalelo kunye neziphumo esinezilawuli cala.

umbane unikwa ukusuka iiclamps 2 kwisigaba output, 4, 6 ukuya izixhobo ezi-. Iintambo kumakishwa.

Okubalulekileyo! lokuzazisa Core wenziwa ngokusekelwe umbala, ukuze phambili umsebenzisi nto iphosakeleyo xa elele kuzo koomatshini, RCD bayaqhubeka ntshikilelo.

Umyalelo: Isigaba ezithathu-uqhagamshelo imitha

Ulandelelwano yezenzo na ngolu hlobo lulandelayo:

1. Ukusuka kwiintambo zamandla ombane ukuya indlu wabeka phezulu okanye intambo komhlaba input kumatshini. Kufuneka wenze ziingcali.
2. Le yolawulo zombane ifakiwe electrometer kunye nezinye izixhobo zokhuselo. Kuxhomekeka inani labasebenzisi esisigxina oomatshini kunye nezibonda ukusuka kwelinye ukuya kwisine. Kwisiskim obuhlangeneyo ukuze izakusetyenziswa endaweni koomatshini umehluko RCD.
3. Nge-kwipali ezine induction lomatshini igalelo iterminal counter wokujoyina ngcingo bebala.
4. Ngokulandelelana efanayo ezinokuthi kwintambo kwimveliso womnatha yangaphakathi. Igalelo kunye neziphumo eqhagamshelwe terminal ezimelene kufuneka ube nombala ofanayo.
5. Ohlanganisa counter lesigaba kunye RCD. Hamba uye uhlale ucingo kwisigaba ezidityanisiweyo kunye zero ngokulandelelana ehambelana Iwawo.

izincomo ngogesi

Phambi kokuba uqalise umsebenzi nokufakelwa zikagesi ngaphakathi kwiqela lenjongo, qiniseka ukuba uhlole off ekwathintela ukusebenza nangengozi ombane igalelo. Kwakhona uhlola imeko ubushushu phezu izibambo lwezixhobo.

Musa ukuqhagamshela ontlantlu-ntathu imitha uxhulumaniso ngqo, amandla apho lingaphantsi ukusetyenziswa womnatha ikhaya. Ukuze wenze oku, umele ukubala kuqala bomthwalo, uze ukhethe icebo efanelekileyo. Uyacetyiswa ukuba yithenge kunye uqhelane ngamandla.

isiphelo

Dibanisa imitha ontlantlu-ntathu kuba zombane ekhaya yenethiwekhi ishishini ngqo. Zonke beye umzobo uxhulumaniso iyafana. Izakufunyanwa kuxwebhu data lesixhobo kwicala le-terminal inshorensi.
