Izinyathelo zokuthi ushintshe ukukhetha kokunikezwa kwamandla

1. Ukukhethwa kokushintshwa kwamandla kagesi kudinga ukunakwa.
1) Khetha ukucaciswa kwe-voltage efanele;
2) Khetha amandla afanele.Amamodeli anesilinganiso samandla angu-30% ngaphezulu angakhethwa ukuze kukhuliswe impilo yokunikezwa kwamandla.
3) Cabangela izici zomthwalo.Uma umthwalo kuyinjini, isibani noma umthwalo we-capacitive, lapho i-current inkulu ekuqaleni, ukunikezwa kwamandla okufanelekile kufanele kukhethwe ukuze kugwenywe ukugcwala ngokweqile.Uma umthwalo kuyinjini, kufanele ucabange ukuma ekugelezeni kwe-voltage reverse.
I-4) Ngaphezu kwalokho, kuyadingeka futhi ukucabangela izinga lokushisa le-ambient elisebenzayo lokunikezwa kwamandla kagesi nokuthi ngabe kukhona yini amadivaysi engeziwe ayisizayo okukhipha ukushisa ukuze kuncishiswe ukuphuma kwamandla aphezulu we-loop.Izinga lokushisa le-ambient linciphisa ijika lesiphongo lamandla okukhiphayo.
5) Imisebenzi ehlukahlukene ingakhethwa ngokuya ngezidingo zohlelo lokusebenza: ukuvikelwa kwe-overvoltage (OVP).Ukuvikelwa ngaphezu kwezinga lokushisa (OTP).Ukuvikelwa kokulayisha ngokweqile (OLP), njll. Umsebenzi wohlelo lokusebenza: umsebenzi wesignali (ukunikezwa kwamandla okuvamile. ukwehluleka kwamandla).Umsebenzi wokulawula kude.Umsebenzi we-Telemetry.Umsebenzi ohambisanayo, njll. Izici ezikhethekile: ukulungiswa kwesici samandla (PFC).Ukunikezwa kwamandla okungaphazamiseki (UPS) kukhetha imithetho yokuphepha edingekayo kanye nesitifiketi sokuhambisana kwe-electromagnetic (EMC).
2. Amanothi ngokusetshenziswa kokushintshwa kwamandla kagesi.Ngaphambi kokusebenzisa ukunikezwa kwamandla, kuyadingeka ukuthi uqale unqume ukuthi ukucaciswa kwe-voltage yokufaka nokuphumayo kuyahambisana yini nokunikezwa kwamandla okuzisholo;
2) Ngaphambi kokuvula amandla, hlola ukuthi ingabe okokufaka nokuphumayo kuxhunywe ngendlela efanele ukugwema ukulimala kwezinto zokusebenza;
3) Hlola ukuthi ukufakwa kuqinile, ukuthi izikulufi zokufaka zixhumene nedivayisi yebhodi lamandla, futhi ulinganise ukumelana nokufakwa kwe-casing kanye nokokufaka nokuphumayo ukuze kugwenywe ukushaqeka kukagesi;
4) Ukuqinisekisa ukuthi indawo ephansi isekelwe ngokuthembekile ukuze kuqinisekiswe ukusetshenziswa okuphephile nokunciphisa ukuphazamiseka;
5) Ukunikezwa kwamandla okuphumayo okuningi ngokuvamile kuhlukaniswa ngokukhipha okuyinhloko nokuphumayo okuyisizayo.Okukhiphayo okuyinhloko kunezici ezingcono kunokukhishwa kwe-axiliary.Ngokuvamile, okukhiphayo okuyinhloko nokukhishwayo okukhulu kwamanje.Ukuze kuqinisekiswe izinga lokulawulwa komthwalo ophumayo kanye namandla okukhiphayo nezinye izinkomba, ngokuvamile kudingeka ukuthi isiteshi ngasinye sithwale okungenani umthwalo ongu-10%.Uma imigwaqo engumsizi ingasetshenziswa, imithwalo efanele ye-dummy kufanele yengezwe emgwaqeni omkhulu.Ukuze uthole imininingwane, sicela ubheke imininingwane yemodeli ehambisanayo;
6) Qaphela: ukushintsha kwamandla njalo kuzothinta impilo yayo yesevisi;
7) Indawo yokusebenza kanye neziqu zokulayisha nazo zizothinta impilo yayo yesevisi.
