Isigaba sesi-3 – Uyiqonda kanjani incazelo ye-“protective impedance”

i-impedance yokuvikela: i-impedance exhunywe phakathi kwezingxenye ezibukhoma nezingxenye ezifinyelelekayo ezifinyelelekayo zezakhiwo zesigaba II ukuze okwamanje, ekusetshenzisweni okuvamile nangaphansi kwezimo ezingaba zephutha entweni, ikhawulelwe kunani eliphephile. Icala 1:Isimo sokuqala ngokuvamile yizimo ezithile ezidinga ukunikezwa kwamandla kagesi aphansi, njengemikhiqizo esebenza nge-adaptha. I-voltage ephumayo ye-adaptha yi-DC12V, DC24V noma i-DC5V. Lezi zingxenye ezinama-voltage aphansi ngokuvamile zingathintwa abasebenzisi ngenxa yokuthi…

Isigaba sesi-3 – Iqondwa kanjani incazelo ye-“functional insulation”

i-functional insulation: ukwahlukanisa phakathi kwezingxenye ze-conductive zamandla ahlukene okudingeka kuphela ekusebenzeni kahle komshini. I-insulation esebenzayo isethwe ngenxa yezidingo zokusebenza zomshini. Emikhiqizweni kagesi, kufanele kube nezingxenye ze-conductive ezinamandla ahlukene (ama-voltage ahlukene). Uma i-voltage yawo wonke ama-conductor anamandla emkhiqizweni iyafana, into esetshenziswayo ayikwazi ukusebenza. Khona-ke, kukhona ukufakwa okusebenzayo phakathi kwezingxenye ezahlukene ze-conductive. Uma sicabanga ukuthi i-voltage elinganiselwe…

Isigaba sesi-3 – Iqondwa kanjani incazelo ye-“reinforced insulation”

ukufakwa okuqinisiwe: ukufakwa okukodwa okufakwe ezingxenyeni ezibukhoma, okunikeza izinga elithile lokuvikela ekushayweni kukagesi okulingana nokufakwa kabili ngaphansi kwezimo ezishiwo kuleli zinga.Njengoba kukhonjisiwe ezithombeni ezimbili ezingezansi, isithombe esingakwesokunxele yisithombe sangemuva sesiqandisi. Ibhodi lesifunda ngaphakathi lingabonakala nge-grille yensimbi esithombeni kwesokunxele, futhi isithombe sangaphakathi isithombe esifanele. Kunezingxenye ezibukhoma ku-PCB, futhi umsebenzisi angakwazi ukuthinta i-grille. Umoya ophakathi kwegebe le-grille…

Isigaba sesi-3 – Iqondwa kanjani incazelo ye-“double insulation”

double insulation: isistimu yokuhlukanisa ehlanganisa kokubili ukufakwa okuyisisekelo kanye nokufakwa okungeziwe Incazelo iwukwenza lula kuphela incazelo yokugquma okuyisisekelo kanye nokwahlukanisa okungeziwe ezingeni, kusetshenziswa igama elilodwa ukuchaza amagama amabili. Njengoba kukhonjisiwe emfanekisweni ongezansi, intambo yokunikezela inezingqimba ezimbili zokuvala, umgodla wocingo ongaphakathi kanye nomgodla wocingo omnyama ongaphandle, ochazwa ngokuthi ukufakwa kabili. Njengoba kukhonjisiwe ezithombeni ezimbili ezilandelayo(ifeni), umgodla…

Isigaba sesi-3 – Iqondwa kanjani incazelo ye-“supplementary insulation”

i-supplementary insulation: i-insulation ezimele isetshenziswa ngaphezu kokufakwa okuyisisekelo, ukuze kuhlinzekwe ukuvikeleka ekushaqekeni kukagesi uma kwenzeka ukwehluleka kokufakwa kwesisekelo I-insulation engaphandle kwe-insulation eyisisekelo futhi ezimele ku-insulation eyisisekelo, futhi ngokuvamile ifinyeleleka kumsebenzisi. I-supplementary insulation, njengoba negama lisho, ingeziwe, futhi ibhekisela ekufakeni okungeziwe ekufakeni okuyisisekelo. Lokhu kuhilela isimiso esiyisisekelo saleli zinga, okungukuthi isimiso sokuvikela okuphindwe kabili. Kunoma iyiphi…

Isigaba sesi-3 – Iqondwa kanjani incazelo ye-“basic insulation”

isisekelo se-insulation: kanye ne-nbsp;i-insulation isetshenziswa ezingxenyeni eziphilayo ukuze kunikeze isivikelo esiyisisekelo ngokumelene nokushaqeka kukagesi Njengoba kukhonjisiwe esithombeni esingakwesokunxele ngezansi, isithombe sekhava engezansi yefeni, futhi isithombe esingakwesokudla isithombe esingenayo ikhava engezansi. Isikhumba socingo oluluhlaza nolunsundu ngaphakathi kwentambo yokuhlinzeka esithombeni esilungile singabhekwa njengokwahlukanisa okuyisisekelo. Ngesikhathi esifanayo, izikhumba zocingo ezimhlophe, ezibomvu nezimnyama ekushintsheni okuxhunywe kugobolondo elimnyama nazo zingahlulelwa…

Isigaba sesi-3 – Iqondakala kanjani incazelo “yohlobo X, thayipha u-Y, uhlobo olunamathiselwe luka-Z”

Uhlobo lokuxhumana luchazwa ngumkhiqizi wohlelo lokusebenza. Ngokuvamile, akuvamile ukukuchaza njengohlobo X, ngoba lokhu kuzoletha ubungozi obungadingekile kumkhiqizi. Ivame ukuchazwa ngokuthi Uhlobo Y. Yebo, uma intambo yamandla isakazwa, ngokuvamile ichazwa ngokuthi Uhlobo Z. Umfanekiso olandelayo ubala imidwebo yokuxhuma yezinhlobo ezintathu zokunamathiselwe. Thayipha okunamathiselwe ku-X: ukuxhuma kwentambo yokuhlinzeka kuqedwa endaweni elungiselelwe ngokukhethekile entweni esetshenziswayo. Ngakho-ke, lapho ushintsha…

Isigaba sesi-3 – Uyiqonda kanjani incazelo “yohlobo lokunamathiselwe ku-Z”

type Z okunamathiselwe kwi-imeyili: indlela yokunamathisela kwentambo yokunikezela ukuze noma yikuphi ukumiselela kuhloswe ukuthi kwenziwe umkhiqizi, umenzeli wakhe wesevisi noma umuntu ofanayo oqeqeshiwe. Isibonelo: Njengoba kuboniswe emfanekisweni, intambo yokunikezela iphonswa kugobolondo lephampu engaphansi kwamanzi nge-epoxy resin. Uma intambo yokunikezela izoshintshwa, i-cast epoxy resin kufanele ichithwe.ukubuka kwangaphakathi kwephampu yamanzi internal view for water pump
