Pfupiso ye overcurrent protection experiment

Munhevedzano yakadzorwa magetsi adapta, ese anoremerwa azvino anoyerera kuburikidza neregulator chubhu.Muchiitiko chekuremerwa, nekukasira kuchaja kwehombe capacitor kana pfupi dunhu rekubuda, iyo inodzora chubhu inoyerera yakakura ikozvino.Kunyanya, kana goho voltage iri pfupi-circuited nokusangwarira, zvose zvokupinza voltage inowedzerwa kuunganidzwa uye kupfura matanda enhevedzano inodzora chubhu, kuitira kuti kupisa muchubhu kunowedzera nechisimba.Kana pasina kudzivirira kwakakodzera, pombi ichapiswa pakarepo.Iyo inopisa inertia ye transistor idiki pane yefuse, saka iyo yekupedzisira haigone kushandiswa kuchengetedza yekutanga.Iwo akateedzana regulator anofanirwa kuchengetedzwa neanokurumidza-kuita zvemagetsi kudzivirira wedunhu.Iyo yemagetsi yekudzivirira yedunhu inogona kukamurwa kuita yazvino-inomisa mhando uye yekucheka-kubvisa mhando.Iyo yekutanga inoganhura ikozvino yechubhu inodzora pazasi pehumwe kukosha kwakachengeteka, nepo iyo yekupedzisira ichibva yacheka ikozvino yeinotonga chubhu kana yakawandisa kana yepfupi-yedunhu tsaona painobuda.

Iyo yakagadziriswa DC simba adapta inoburitsa yakasimba yakaipa yakakwira voltage, uye yobva yabatanidza imwe chikamu chayo kune cathode uye imwe kune anode.Munda wemagetsi wakasimba unogadzirwa pakati pecathode uye anode, uye munda wemagetsi pamatanda maviri anodarika kusimba kwakatarwa, uye ipapo ichabuda.Pane ionization yakatenderedza munda wemagetsi, uyezve pane akawanda maerekitironi nemaoni.Mushure mechinguva, mhepo yakasimba kwazvo yemagetsi inogona kunzwika kutenderedza munda wemagetsi.Muchiedza chakaderera, kupera simba kwepepuru - yebhuruu corona inogona kuoneka kutenderedza.Uyezve, kutenderedza munda wemagetsi, pachava netara yakawanda, guruva uye zvimwe zvimedu zvakasanganiswa neoni kana maerekitironi, izvo zvinozoenda kune mapango pasi pekuita kwesimba remagetsi.Huremu hweerekitironi idiki kwazvo, asi inofamba nekukurumidza, saka inonyanya kupomerwa zvakaipa.
