①Kunezimpawu ezimbili ezithi “I” kanye “O” ekushintsheni kwamandla kwezinye izinto ezinkulu.Uyazi ukuthi lezi zimpawu ezimbili zisho ukuthini?
U-“O” ucisha ugesi, u-“I” ukhanyisa amandla.Ungacabanga ngo-“O” njengesifinyezo sokuthi “cisha” noma “okukhiphayo”, okusho ukuthi vala nokuphumayo, kanti “Mina” yisifinyezo sika-“input”, okungukuthi “Faka” okusho ukuthi vula.
②Ngakho zavelaphi lezi zimpawu ezimbili?
Ukuze kuqinisekiswe ukusebenza okuzinzile kwemishini kagesi phakathi neMpi Yezwe II, kuyadingeka ukuhlanganisa ukushintshwa kwemishini kagesi emikhakheni ehlukahlukene efana nebutho lezempi, i-navy, i-air force kanye ne-logistics, kanye nezinga le-shintsha isikhethi.Ikakhulukazi, ukuhlonzwa kwamaswishi kudinga ukuqinisekisa ukuthi amasosha nabasebenzi abanakekelayo emazweni ahlukahlukene bayakwazi ukukubona futhi bawasebenzise ngendlela efanele ngemva kwemizuzu embalwa nje yokuqeqeshwa.
Unjiniyela wacabanga ukuthi inkinga ingaxazululeka ngokusebenzisa ikhodi kanambambili eyayivame ukusetshenziswa emazweni ngamazwe ngaleso sikhathi.Ngoba kanambambili "1" isho ukuvuleka futhi "0" isho ukucisha.Ngakho-ke, kuzoba khona u-“Mina” no-“O” ekushintsheni.
Ngo-1973, i-International Electrotechnical Commission (IEC) yaphakamisa ngokusemthethweni ukuthi u-“I” kanye no-“O” kufanele kusetshenziswe njengezimpawu zomjikelezo wokucisha amandla ezicacisweni zobuchwepheshe ezihlanganisiwe.Ezweni lami, kuyacaca futhi ukuthi "Mina" kusho ukuthi isekethe ivaliwe (okungukuthi, ivuliwe), futhi "O" isho ukuthi isekethe inqanyuliwe (okungukuthi, ivaliwe).
③Indlela yokukhethainkinobho yokushintsha?
1. Izinto ezihlanganisiwe
Amaswishi epulasitiki avamile, nakuba efaka i-insulating, ayavutha futhi athambekele ezingozini zokuphepha.Kunconywa ukukhetha iswishi enensimbi engagqwali enamathiselwe ngaphezulu ukuze kuvinjelwe ukuxhumana nokuthuthukisa ukuphepha.
2. Hlanganisa amakha
Khetha engenambala futhi engenaphungaUkushintsha kwamandla epulasitiki ye-PC.
3. Ilogo ehlanganisiwe
Khetha imikhiqizo enesitifiketi se-3C, CE.
4. Hlanganisa imisindo yenkinobho
Uma usebenzisa iswishi, khetha iswishi yamandla enomsindo opholile futhi engezwani nokuma.
5. Hlanganisa ukubukeka komkhiqizo
Inkinobho yokukhetha inendawo ekhanyayo, engenasici, enamabala amnyama.Ukubonakala kufanele kube bushelelezi futhi bushelelezi, futhi umbala kufanele ufane.
④Uyifaka kanjani i-Power switch?
1. Ngaphambi kokufaka inkinobho yamandla, kuyadingeka ukuvala ugesi oyinhloko ekhaya ukuze ugweme ingozi yoxhumana nabo;
2. Ngaphambi kokufaka, hlola ukuthi izesekeli zeswishi yamandla ziphelele yini;
3. Hlukanisa umehluko phakathi kwezintambo, okuyintambo ephilayo, intambo emaphakathi, nentambo yaphansi.Hlanganisa indlela yezintambo yezikhonkwane zokushintsha amandlaIsikhumuloukuxhuma kahle isekethe;
4. Ngemva kokufakwa kwenkinobho, sebenzisa ithuluzi lokuhlola ukuze uhlole ukuze uqinisekise ukuthi ukushintsha kujwayelekile.
