Ukuthenga ngaphakathi nohlelo

Mayelana nalolu hlelo lokusebenza

Finyelela konke nge-trail yezinsuku ezi-3!
-Inhloso yalolu hlelo lokusebenza ukunikeza isiqondiso nokwenza izibalo zemboni yokufaka ugesi.
-Uhlelo lokusebenza lunikeza isiqondiso sesinyathelo ngesinyathelo sezibalo zobunjiniyela, sinikeza imiphumela yekhebula, i-breaker, umhlaba, i-PFC, nosayizi wesiqu.
-Izibalo zithobela Amazinga WaseBrithani (BS) futhi zethulwa ngamayunithi wemethrikhi.
-Imiphumela kanye nezibalo kungenziwa ngefomethi ye-PDF, okuvumela ukwaba kalula futhi kugcinwe ohlwini lwamafayela eselula.

Ikhasi lamakhebuli ne-breaker:
-Inhloso yaleli khasi lesibali ukuthola usayizi ofanelekile wekhebula le-copper, i-circuit breaker, noma usayizi we-fuse ngokusekelwe kunani lomthwalo elinikeziwe ngokuvumelana ne-IEE Wiring Regulation BS 7671.
-Leli khasi livumela abasebenzisi ukuthi bafake izimo zokufaka nezinto ezizungezile isinyathelo ngesinyathelo. Inhloso ukuhlonza ngokunembile izici zokuhlehla okuthonywa uhlobo lwe-circuit breaker, izinga lokushisa elizungezile, izindawo zokuqoqana, njll.Le datha ibalulekile ekubaleni amandla amanje kusetshenziswa amanani ahlelwe ku-appendix 4, kucatshangelwa indlela yokufaka ekhethiwe kanye nezinhlobo zamakhebula, ekugcineni kunqunywe ezifanele. isilinganiso sosayizi wesiphakeli esijwayelekile nosayizi wekhebula.
-Ukwehla kwamandla kagesi kuyacatshangelwa lapho kukhethwa ama-circuit breaker namasayizi wekhebula.
-Umphumela uhlanganisa amafomula, umhlahlandlela wokubala wesinyathelo nesinyathelo, kanye nezinkomba ukuze kube lula kuwe.
QAPHELA: Ukuchofoza inkinobho yokubala kungase kubangele ukubambezeleka, ikakhulukazi kumadivayisi eselula amadala, njengoba inqubo yokubala nokusesha kwetafula lesithenjwa kuthatha isikhathi. Nokho, kungaphansi kancane nje komzuzu, ngakho-ke sicela ubekezele.
Ikhasi Lomhlaba:
-Inhloso yaleli khasi lesibali ukunquma kusengaphambili ubude obulinganiselwe bezintambo zomhlaba kanye nenani noma ubude be-mesh strip nosayizi ngokulandela imihlahlandlela ye-BS 7430:2011.
-Leli khasi lihlinzeka ngemiphumela esheshayo yokukhetha, ithebula elinemininingwane kanye namafomula wokubala wesinyathelo nesinyathelo kanye neshadi lokumelana nomhlabathi.
-Ngaphezu kwalokho, leli khasi lesibali lingaveza umbiko wokumelana nomhlabathi ngokusebenzisa izilinganiso zokumelana nenhlabathi ezitholakala ngethuluzi le-Megger eline-four, elivame ukubizwa ngokuthi indlela ye-Wenner.
Ikhasi Lokulinganisa Isiqu:
-Inhloso yaleli khasi lesibali ukunquma usayizi wetrunk wensimbi odingekayo ukuze kufakwe iqembu lezintambo ezijwayelekile, kucatshangelwa izici zomthamo ezivezwe kumathebula 5E kanye no-5F ku-BS 7671/Isithasiselo 5.
-Leli khasi linikeza imiphumela esheshayo yokukhetha, kanye netafula eliphelele namashadi omthamo wokuhlala.
-Izintambo ezifakiwe eziphambana nezingxenye ze-trunk akufanele zeqe u-45% wendawo ye-trunk yangaphakathi ephambanayo ecatshangelwa njengaku-BS 7671.
Ikhasi le-PFC:
-Inhloso yaleli khasi lesibali ukunquma usayizi olungile we-capacitor bank kumandla asebenzayo we-kVAR "Q" kanye ne-Microfarad "µF" yesinxephezelo sesici samandla.
-Leli khasi lihlinzeka ngemiphumela esheshayo yokukhetha yeBhange le-Capacitor, kanye nemingcele enemininingwane kanxantathu wamandla anezibalo.
-Imithwalo ye-capacitive inomphumela ophambene nesistimu kagesi emithwalweni ye-inductive, ngakho-ke ukwethula i-capacitor ohlelweni lwe-inductive kungathuthukisa isici samandla.
-Isici samandla esihle singaholela ekusebenzeni kahle kukagesi ngakho-ke izindleko eziphansi zebhili.
Ikhasi losayizi we-Conduit:
-Inhloso yaleli khasi lesibali ukunquma usayizi wentambo kagesi edingekayo ukuze kufakwe iqembu lezintambo ezijwayelekile, kucatshangelwa izici zomthamo ezichazwe kumathebula 5A, 5B, 5C & 5D kokuthi BS 7671/Appendix 5.
- Leli khasi linikeza imiphumela esheshayo yokukhetha, kanye netafula eliphelele namashadi omthamo wokuhlala.
- Ubuncane bosayizi wepayipi ukuthi ukuba nesici esilingana noma esikhulu kunesamba sezinto zekhebula esicatshangelwa njengaku-BS 7671.
