Indlela yokwenza icandelo ukukhetha kwemigaqo intambo?

Namhlanje linokubizwa ngokuba ilixa ukulungiswa: ukwakha izindlu ezintsha, kwaye uninzi izakhiwo ezikhoyo ziyalungiswa ngenkuthalo. Oku kuyinyaniso ngakumbi izakhiwo kwicandelo labucala, ezakhiwa basukela 50 ukuya kwi 80. Isetyenziswa ngexesha izinto sele ngokuyinxenye ezilahlekileyo iipropati zabo ngenxa yokuguga zendalo, ukuphuculwa zomhlaba baye kwakhokelela ukuvela igridi lwamathanda ezindongeni, njl .. Ukongeza, kukutshintsha uyilo uza kwaye, okubalulekileyo, iimfuneko obuphezulu isakhiwo ezisebenzayo. Umzekelo, ukuba phambi kokuba ukukhetha cable umnqamlezo-icandelo le umthwalo xa esenza kweentambo indlu kwenziwe ngokusekelwe ekusetyenzisweni lilonke akukho ngaphezulu kwe 1-1.5 kilowatts, kodwa ngoku ezi amaxabiso anda kakhulu. Ngoku ke kancinane ukuchophela kilowatts 3 (ngoku Ampere 16). Ngenxa yoko, bobabini emakhayeni zabucala zokuhlala kufuneka ihambelane neemfuno ezintsha, ukuba enze kukhethwe intambo cross-candelo kwaye utshintshe yonke iintambo. Asinako ukunyuka akulambathi zokulungiswa yokuqala kwizihloko abayichukumisayo: into yokuba uninzi iindlela replacement yatshabalalisa umhombiso wangaphakathi. Ukuze ukubeka intambo elitsha, kaninzi ezindongeni Stroebe ntoni. Kakade ke, ungasebenzisa i plinth ngentambo channel kunye neebhokisi zeplastiki, kodwa esi sisombululo akufanelekile zonke ingaphakathi.

Njengoko ukhetho lwenziwa candelo le ntambo? Masithi ngoko nangoko: oku akukho dili enkulu. Lo msebenzi ngisho yesikolo. Kufuneka uhlale phantsi kunye usiba kunye nephepha, yenza uluhlu abathengi amandla kakhulu ezinamandla ukuhlalutya yeyiphi kwezi ziza .Yiyo ngaxeshanye. Makhe sijonge umzekelo elula yokwenza njani iindidi ngentambo ubukhulu.

Kukho umsebenzi - ukuqhagamshela kwi zombane kumatshini wokuhlamba. Ukhetho intambo cross-candelo iqala uviwo lwe data yokundwendwela isixhobo - kufuneka afumane ixabiso ukusetyenziswa yamandla. Ekubeni ngokunxulumene koomatshini abavelisi kancane olukhohlisayo, kufuneka ukusondela ngenyameko lo mba. Ithi: "Amandla - 200 Watts". Noko ke, ngezantsi unako ebonisa iimpawu element zokufudumeza ukufumana. Kuba kuthiwa ngenxa 2 kW. Ngoko ke, umlinganiselo kumatshini liyadla 2.2 kW. Kubalulekile ukuba lithathele ingqalelo ezinjalo "zochuku", okanye intambo ekhethiweyo ngokungachanekanga nje ngomlilo ngaphandle. Kuhleli ukuze enze icandelo yokhetho le intambo.

Phakathi yangoku kunye ixabiso amandla unxulumano ngqo. Le ifomyula:

P = U * I,

apho P - amandla; U - ombane; I - ngoku.

Amandla abendlu factor lokuqala rhoqo kwi-220 volts.

Ukufunda koomatshini ixabiso lamandla (2.2 kW) eziyimfuneko ukuze formula ngasentla ukubala yangoku:

I = 2200 W / 220 = 10 Amperes

I look-up iitafile ukusetyenziswa zilandelayo, apho babalungiselele ukuthotyelwa intambo umqhubi, icandelo layo umnqamlezo, ngokubekwa indlela (evulekileyo, kwityhubhu eludongeni) kunye nexabiso langoku. Tables zibonelelwa kule ncwadi "Imithetho Ufakelo Electrical." Kananjalo ifumaneka kuthungelwano lwehlabathi - olu lwazi lufumaneka esidlangalaleni. Kulo mzekelo, ukuba 'athathe "of iingcingo zekopolo, icandelo labo kufuneka ubuncinane 0.75 square metres. mm (current e Ampere 15 lokujongana nokufakelwa open). Kakade ke, i-30% eludinini ke ngokugqithiseleyo, kodwa ukususela ucingo esidla ikwindawo evulekileyo, i ngoku avumelekile ingaphantsi. Ngaphezu koko, eli candelo elandelayo elisezantsi (0.5) yenzelwe amps-11, nto leyo ayanelanga.

Xa ukhetho ezithunyelwe ikhaya usebenzisa lo mgaqo. Umahluko kukuba kufuneka ithathele ingqalelo udibaniso ngamandla izixhobo aokusetyenziswa ngexesha elinye zifakwe kwi naliphi na isebe.
