Muri iki gihe, ikibazo cy’ibura ry’amashanyarazi ku isi kirimo kwiyongera cyane. Ibigo byinshi n’abantu ku giti cyabo bahitamo kugura amamashini akoresha amashanyarazi kugira ngo bagabanye imbogamizi ku musaruro n’ubuzima buterwa no kubura kw’amashanyarazi. Alternator ya AC ni kimwe mu bintu by’ingenzi kuri seti yose ya generator. Uburyo bwo guhitamo alternator yizewe, inama zikurikira zigomba kwitabwaho:
I. Ibiranga amashanyarazi:
1. Sisitemu yo gushyushya: Muri iki cyiciro, sisitemu yo gushyushya ya alternator ya AC isanzwe ifite ubwiza bwo hejuru ni iyo kwishyushya ubwayo, muri rusange ikaba ifite icyuma gipima amashanyarazi (AVR). Ingufu zo gusohora za rotor yo gushyushya zijya kuri rotor yo mu rugo binyuze muri rectifier. Igipimo cyo guhindura amashanyarazi gihamye cya AVR ahanini ni ≤1%. Muri byo, AVR ifite ubwiza bwo hejuru ifite kandi imirimo myinshi nko gukora kuri parallel operations, kurinda frequency nke, no guhindura amashanyarazi yo hanze.
2. Gushyiramo ubushyuhe n'ubuvange: Uburyo bwo gukingira bw'ibikoresho byo mu bwoko bwa alternator nziza muri rusange ni "H", kandi ibice byayo byose bizunguruka bikozwe mu bikoresho byakozwe mu buryo bwihariye kandi bishyirwamo uburyo bwihariye. Alternator ikora ahantu habi kugira ngo itange uburinzi.
3. Gufunga no gukoresha amashanyarazi: Stator ya alternator nziza izaba ishyizwemo ibyuma bikonje bifite ubushobozi bwo kwinjira neza mu kirere, ibyuma bifite imiterere ibiri, imiterere ikomeye kandi bifite ubushobozi bwo gukingira.
4. Interference kuri telefoni: THF (nk'uko byasobanuwe na BS EN 600 34-1) iri munsi ya 2%. TIF (nk'uko byasobanuwe na NEMA MG1-22) iri munsi ya 50
5. Kwivanga kwa radiyo: Ibikoresho byiza bitagira uburoso na AVR bizatuma habaho kwivanga guke mu gihe cyo kohereza radiyo. Iyo bibaye ngombwa, hashobora gushyirwaho ikindi gikoresho cyo gukumira RFI.
II. Ibiranga imikorere ya mekanike:
Ingano y'uburinzi: Ubwoko busanzwe bwa moteri za AC zo ku butaka ni IP21, IP22 na IP23 (NEMA1). Niba hari uburinzi buri hejuru, ushobora guhitamo kongera urwego rw'uburinzi rwa IP23. Ubwoko busanzwe bwa moteri za AC zo mu mazi ni IP23, IP44, IP54. Niba ukeneye kunoza urwego rw'uburinzi, nko ku nkombe z'inyanja, ushobora gushyira moteri za AC ibindi bikoresho, nk'ibishyushya, ibyuma biyungurura umwuka, nibindi.
Ibura ry'amashanyarazi ku isi ryiyongereye cyane ku isoko rya alternator/generators za AC. Ibiciro by'ibikoresho bya generators za AC nka disiki na rotors byarazamutse cyane. Itangwa ry'amashanyarazi ni rike. Niba ukeneye amashanyarazi, ushobora kugura generators za AC vuba bishoboka. Igiciro cya generators za AC nacyo kiriyongera buri gihe!
