Indlela yokwenza kwesigaba Kukhethwa ikhebula?

Namuhla Ingabizwa kufanele ngokuthi inkathi ukulungisa: ekwakheni amakhaya amasha, futhi iningi izakhiwo ezikhona ukukhuthalele lalungiswa. Lokhu kuyiqiniso ikakhulukazi wemboni izakhiwo yangasese, ezakhiwa ngezinyanga uhla kusuka 50s kuya 80s. Esetshenziswe ngesikhathi izinto kakade ingxenye walahlekelwa impahla yabo ngenxa yokuguga zemvelo, kungenzeka inhlabathi ngcono sezishiye ukuvela grid imifantu izindonga, njll .. Ngaphezu kwalokho, umklamo esishintshile lisondela futhi, okubaluleke kakhulu, kukhona izidingo ephakeme ukuze isakhiwo sokusebenza. Ngokwesibonelo, uma ngaphambi kukhethwa ikhebula cross-section umthwalo uma lenza yasendlini wiring senziwa ngesisekelo ukusetshenziswa ingqikithi kilowatts akukho kuka 1-1.5, kodwa manje lezi amanani kakhulu anda. Manje kukhona kancane osekuyisikhathi 3 kilowatts (samanje Ampere 16). Ngakho, kokubili emakhaya abo nasemaHholo zokuhlala kumelwe abe ngokuhambisana nezidingo entsha, ukuze afeze ukukhethwa ikhebula cross-section futhi ushintshe yonke wiring. Asibi ize ukulungisa ekuqaleni ngezihloko athinteka: yokuthi iningi izindlela esikhundleni obhubhisayo umhlobiso ingaphakathi. Ukuze akuveze ikhebuli entsha, avame ezindongeni Stroebe ukukwenza. Yiqiniso, ungasebenzisa plinth nge ikhebula isiteshi kanye amabhokisi plastic, kodwa lokhu isixazululo awulungele zonke ingaphakathi.

Njengoba Ukukhetha wenziwa ingxenye ikhebula? Ake sithi zisuka: lena akunandaba ngempela. Umsebenzi ukusingatha ngisho wesikole. Udinga ukuba uhlale phansi kanye ipeni ephepheni, ukwenza uhlu enamandla kakhulu amandla abathengi kanye ukuhlaziya ukuthi yiziphi uzobe ovuthayo kanyekanye. Ake sibheke isibonelo esilula zendlela yokwenza ezihlukahlukene ikhebula osayizi.

Kukhona umsebenzi - ukuxhuma kwi-kagesi umshini wokuwasha. Kukhethwa ikhebula cross-section kuqala ngokuhlola yephasiphothi idatha zedivayisi - kufanele uthole ukubaluleka ukusetshenziswa amandla. Njengoba maqondana imishini abakhiqizi kancane olukhohlisayo, udinga asondele ngokucophelela lolu daba. Lo mBhalo uthi: "Amandla - 200 Watts". Nokho, ngezansi ungathola inkomba izici Ukushisa isici. Ukuze kuthiwa 2 kW. Ngakho, ngo-inani umshini ibusa 2.2 kW. Kubalulekile ukuze kubhekelelwe "trifles" enjalo, noma ikhebula ngokungalungile akhethiwe nje zishe. It uhlala ukwenza kwesigaba ukukhethwa le ntambo kagesi.

Phakathi wamanje kanye ukubaluleka amandla okusobala. Ifomula:

P = U * mina,

lapho P - amandla; U - voltage; Mina - zamanje.

Amandla yasendlini isici sokuqala njalo 220 volts.

Ukufunda imishini amandla value (2.2 kW) ezidingekile ifomula ngenhla ukubala wamanje:

I = 2200 W / 220 = 10 Amperes

Ukusetshenziswa look-up Lamathebuli lalandzelako, okunikeza ukuhambisana ikhebula umqhubi impahla, esigabeni yayo cross, ebeka indlela (evulekile, endaweni tube ogangeni) kanye nenani lamanje. Amathebula ezilungiselelwe kule ncwadi "Imithetho Ukufakwa kagesi." Lemisebenti ingaphindze ezitholakala inethiwekhi global - lolu lwazi lutholakala esidlangalaleni. Kulokhu, uma "thatha" izintambo zethusi, esigabeni sabo kumele okungenani ibe 0.75 metres square. mm (samanje Ampere-15 bakha imizila edingekayo yokwenza evulekile). Yiqiniso, i-30% margin kuwukweqisa, kodwa kusukela ngezintambo ongajwayele isebangeni evulekile, lamanje ovumelekile incane. Ngaphezu kwalokho, olandelayo engxenyeni engezansi (0.5) yakhelwe Amps 11, okuyinto enganele.

Lapho ukhetha ikhaya ezithunyelwe usebenzisa isimiso esifanayo. Umehluko wukuthi wena kufanele inake isamba amandla amadivayisi kungenziwa kanyekanye ifakwe ngasiphi egatsheni.
