Ake sibheke indlela ukubala wamanje wenziwa emandleni

Ngaphambi kokuqhubeka umklamo kagesi ekhaya lakho, kufanele wenze uhlelo lokukhokha nge inkomba imithwalo Kulindeleke emagcekeni nobude izigaba ngazinye ikhebula. Ukuze ahlanganise isikimu ezinjalo kanye nesidingo ukubala "amandla" zamanje. Mapping Lungile ikhaya kagesi ziyoyizwa izigaba ledzingekako izintambo ukuthi uyobavikela wiring yakho okweqile kanye, ngokufanele, kungenzeka umlilo. Ake sibone, kodwa siyini ekubalweni "amandla" zamanje.

Ukukhetha Ofanele amadivayisi ukushintsha futhi ikhebula cross-section kuncike amanani ahlukene kwemigomo amanethiwekhi kagesi. Into ebaluleke kakhulu phakathi kwazo kagesi. Futhi at the stage of ukuklama lezi zimiso kungenziwa kuphela kunqunywa izibalo zezibalo. Kubaluleke kakhulu kubhekwa "amandla" sibalo samanje ezintathu okhombisa amanethiwekhi, lapho umthwalo kumelwe ibekwe ngokulinganayo phakathi izigaba, ukugwema Ukuhlanekezelwa. Nokho, ezisemadolobheni amanethiwekhi yokuhlala, lezi izibalo kufanele kwenziwe ekuklanyweni hhayi kuphela isihlangu kodwa futhi zokuhlala.

"Amandla" ukubala wamanje inikezwe amandla kagesi amanani ezaziwayo, ubunjalo imithwalo kanye supply voltage. Ukuze uthole amapayipi owodwa esigabeni usebenzisa le ndlela elandelayo: Mina = P / (U × cosφ), lapho:

• U - langempela voltage ukubaluleka ulinganiswa volts;
• cosφ - elihambisana amandla isici.

Kuye uhlobo amandla umthwalo isici kuyakhethwa. Ngakho, i-umthwalo asebenzayo (izakhi heater, izibani incandescent) kuba okungenani zilingana indlela eya ebunyeni. Nokho, lapho ucabangela ukuthi umthwalo resistive njalo ingxenye esisheshayo ke ukubala Kuyinto evamile ukusebenzisa ukubaluleka cos, ilingana 0.95. Lapho ukubala umthwalo, esibonakala by okusezingeni eliphezulu amandla esisheshayo (sokuqala esiminyanisa ukukhanyisa, motors kagesi, lokungeniswa somlilo, Welding Transformers , njll) Ithathwe kusho inani cosφ, ilingana 0.8.

Ukuze ifomula okhombisa AC amandla supply kuyodingeka ifomu elandelayo: Mina = P / (1,73 × U × cosφ).

Ukuze ezintathu okhombisa amanethiwekhi amandla isici imithwalo asebenzayo futhi esisheshayo ngokuphelele ezifanayo owodwa esigabeni amanethiwekhi.

Ngakho, esebenzisa amafomula ngenhla kuyadingeka ukuze ukuqhuba izibalo wawo wonke amandla imithwalo kagesi anamuhla, okumele asetshenziswe endaweni ethile.

Esigabeni esilandelayo izibalo zethu, kuyoba kukhethwa ikhebula cross kwesigaba. Nakuba izincwadi yezobuchwepheshe ungakwazi ngokuvamile ukuthola into efana "ukubala ikhebuli yamandla" Eqinisweni, it is hhayi ibalwa, kodwa namanje "ukukhetha". Ngaphansi ukuqonda ukucabanga ifomula sokunquma umthwalo lamanje ngenhla. Ephambi kwezinduna amagugu ezithile wamanje kanye voltage ikhebula cross kwesigaba ekhethiwe kusukela kumathebula look-up. Lezi amatafula ezibukwayo kakhulu futhi asidingi incazelo enemininingwane. Wena kuqala ukhethe impahla wire: ithusi noma se-aluminium, bese voltage ukunikezela ukubaluleka wamanje kunqunywa ikhebula cross-section.

Lapha, empeleni, sabuka kanjani ukubala umthwalo kagesi kanye ezikhethiwe cross-ingxenye izintambo yamaphrojekthi ugesi.
