Impendulo: Kungase kube ngenxa yokuxhumana okubonakalayo koxhumana nabo abasizayo bokushintsha kulayini noma inkinga yokusetha ingemuva, ngakho hlola umugqa nezilungiselelo zohlelo lwangemuva.
4. Yini okufanele ngiyenze uma ukuphuma kwe-relay kungavamile?
Impendulo: Hlola izilungiselelo zezintambo noma zokudlulisela.Kunezindlela ezintathu zokuphumayo kokuphumayo kokudluliswayo: ileveli, ishayela kanye ne-alamu.Kunezindlela ezimbili zokuphuma kweleveli ne-pulse.Ukuze uthole izintambo ezithile, sicela ubheke imanuwali yomkhiqizo noma uthinte abosizo lobuchwepheshe lomkhiqizi ofanele.
5. Yini okufanele ngiyenze uma isignali yokuphuma kwedijithali ingajwayelekile?
Impendulo: Hlola izilungiselelo zezintambo noma zokuphuma kwedijithali.Izindlela zokuphuma kwedijithali zihlanganisa okukhipha amandla kagesi kanye nokuphuma kwe-alamu.Ukuze uthole izintambo ezithile, sicela ubheke imanuwali yomkhiqizo noma uthinte abosizo lobuchwepheshe lomkhiqizi ofanele.
6. Yini okufanele ngiyenze uma kungekho nkinga ngocingo lwensimbi kodwa kungekho ukuxhumana?
Impendulo: Izilungiselelo zezinsimbi, hlola ukuthi ingabe ikheli lokusetha insimbi nezinga le-baud liyahambisana yini nesofthiwe yesistimu.Wonke amathuluzi axhunywe kumzila ofanayo wokuxhumana kufanele aqinisekise ukuthi amakheli awadluleli futhi amanani e-baud ayafana.
7. Yini okufanele ngiyenze uma i-backlight yensimbi ikhanya?
Impendulo: Hlola izilungiselelo ze-alamu zensimbi, ezinye izinsimbi zizokhanyisa i-backlight uma zisesimweni se-alamu.Uma insimbi isesimweni se-alamu, i-backlight yensimbi izokhanyisa, ngemva kokukhansela i-alamu, ukukhanya okungemuva kuzobuyela kokujwayelekile.
8. Yini okufanele ngiyenze uma ithuluzi lingakwazi ukufaka isilungiselelo sepharamitha?
IMP: Kungenzeka ukuthi igama-mfihlo libekwe ngephutha, sicela uxhumane nosekelo lobuchwepheshe ukuze uthole usizo.
9. Yini okufanele ngiyenze uma isibonisi samanje kanye ne-voltage silungile, kodwa isibonisi samandla singavamile?
Impendulo: Uma kunenkinga ye-voltage noma yezintambo zamanje, hlola ngokucophelela ukuthi i-voltage noma izintambo zamanje ziyashintshaniswa noma zihlehliswa phakathi kwezigaba.
10. Yini okufanele ngiyenze uma isignali yokuphuma kwe-analog iphindwe kabili?
Impendulo: Kungase kubangelwe izintambo zesistimu.Ukuthi imiphumela ye-AO emibili isetshenziswa ngesikhathi esisodwa futhi iziphetho ezingezinhle zisekelwe ngesikhathi esisodwa.Uma kunjalo, imiphumela emibili izophazamisana.Kunconywa ukufaka isihlukanisi sesignali ukuxazulula inkinga.
11. Yini okufanele ngiyenze uma imitha ingenaso isibonisi?
Impendulo: Qinisekisa ukuthi ingabe i-voltage yokufaka yomthombo wamandla ijwayelekile, hlola ukuthi ingabe kukhona yini uxhumano lwe-virtual emugqeni ongenayo wokuphakelwa kwamandla wethuluzi, futhi usebenzise i-multimeter ukuze ulinganise ukuthi ingabe i-voltage yetheminali yomugqa engenayo yethuluzi ijwayelekile futhi ihlangabezana nezidingo zoku-oda.ukuthi izidingo ziyahlangatshezwa yini.Qiniseka ukuthi isisetshenziswa samandla esisizayo esifanelekile (AC/DC85-265V) sengeziwe kutheminali yamandla ayisizayo yethuluzi.I-voltage yesiza yamandla edlula ububanzi obushiwo ingase ilimaze ithuluzi futhi ayikwazi ukutholwa.Ungasebenzisa i-multimeter ukukala inani le-voltage ye-axiliary power supply.Uma i-voltage yokunikezwa kwamandla ijwayelekile futhi imitha ingenakho isibonisi, ungacabanga ukucisha bese uvule kabusha amandla.
12. Yisiphi isizathu esenza ithuluzi lihluleke ukuveza umsebenzi odingekayo?
Impendulo: Hlola ukuthi imitha yale modeli iqukethe lo msebenzi.Imitha oyi-odile kufanele iqonde imisebenzi equkethe.Amamodeli ahlukene anemisebenzi ehlukene, ngakho-ke akufanele uxhume ngokungaboni noma uwasebenzise ngokungaboni.
13. Kungani inani elibonisiwe lamanje kanye ne-voltage inkulu kakhulu noma incane kakhulu (ubudlelwane obuningi nenani langempela)?
A: Isilinganiso se-transformer ye-CT ne-PT yemitha ngokwayo ayisethiwe.Ungahlola imanuwali yomsebenzisi enamathiselwe imitha noma uxhumane nosekelo lobuchwepheshe ngokuqondile ukuze uthole usizo.
14. Kunamaphutha athile asobala kumanani abonisiwe we-voltage kanye nezamanje (isibonelo, i-voltage yesigaba B inkulu kakhulu) kungani?
Impendulo: Kungase kube inkinga ngokusetha indlela yezintambo.Shintsha indlela ye-wiring ye-voltage noma yamanje ngokuya ngezintambo zangempela zesistimu kuzilungiselelo zensimbi.
15. Yini okufanele ngiyenze uma amanani akaliwe ka-U, I, P, njll. engalungile?
Impendulo: Kungaba inkinga yezintambo noma inkinga yokusethwa.Okokuqala, udinga ukuqinisekisa ukuthi i-voltage efanele kanye nezimpawu zamanje zixhunywe kumitha.Ungasebenzisa i-multimeter ukukala isignali kagesi, futhi usebenzise imitha yokubopha ukuze ulinganise isignali yamanje uma kunesidingo.Okwesibili, qiniseka ukuthi ukuxhumeka komugqa wesignali kulungile, njengegama elifanayo ekupheleni kwesignali yamanje (okungukuthi, ukuphela komugqa ongenayo), nokuthi ngabe ukulandelana kwesigaba sesigaba ngasinye akulungile.Imitha yamandla emisebenzi eminingi ingakwazi ukubona isibonisi sokusebenzelana kwamandla, kuphela esimweni sokudluliswa kwamandla ahlehlayo, idatha yamandla asebenzayo ayilungile, futhi idatha yamandla asebenzayo ayilungile ekusetshenzisweni okuvamile.Uma uphawu lwamandla asebenzayo lunegethivu, kungenzeka ukuthi imigqa yamanje yokufaka neyokukhiphayo ixhunywe ngokungalungile.Impela, uxhumo olungalungile lokulandelana kwesigaba luzophinda lubangele isibonisi samandla esingavamile.Ngaphezu kwalokho, kufanele kuqashelwe ukuthi amandla aboniswa imitha yinani legridi eyinhloko.Uma i-multiplier ye-voltage kanye ne-transformer yamanje ebekwe kumitha ayihambisani ne-multiplier ye-transformer yangempela esetshenzisiwe, ukuboniswa kwamandla kwemitha nakho kuzobe kungalungile.Amandla kagesi kanye nobubanzi bamanje kumitha akuvunyelwe ukuguqulwa ngemva kokuphuma embonini.Inethiwekhi yezintambo ingashintshwa ngokwendlela yokuxhumana yangempela esizeni, kodwa ukulungiselelwa kwendlela yokufaka izintambo kumenyu yokuhlela kufanele kuhambisane nendlela yangempela yokufaka izintambo, ngaphandle kwalokho kuzophinde kuholele olwazini olungalungile lokubonisa.
16. Yini okufanele ngiyenze uma amandla kagesi engalungile?
Impendulo: Kungase kube inkinga yezintambo.Ukuqoqwa kwamandla kagesi emitha kusekelwe esilinganisweni samandla.Okokuqala bheka ukuthi inani lamandla emitha liyahambisana yini nomthwalo wangempela.Imitha yamandla enemisebenzi eminingi isekela ukukalwa kwamandla okunezindlela ezimbili.Endabeni ye-wiring engalungile, lapho amandla asebenzayo aphelele engalungile, amandla azoqoqwa kumandla asebenzayo aphambene, futhi amandla asebenzayo asebenzayo ngeke aqoqwe.Inkinga evame kakhulu esetshenziswa ensimini ukuxhuma okuphambene kwezintambo ezingenayo neziphumayo ze-transformer yamanje.Imitha yamandla enemisebenzi eminingi ingabona amandla asebenzayo asayiniwe wesigaba sokuhlukanisa.Uma amandla engekho, kungase kube izintambo ezingalungile.Ukwengeza, ukuxhumeka okungalungile kokulandelana kwesigaba kuzophinde kubangele ukungavamile kwamandla kagesi wemitha.
