Ndechipi residual zano kuitika

Electrical mano vose yakatipoteredza. Dzimwe nguva, kunyange pashure kusiya nebhasikoro kunze kweguta, hatifaniri kukanganwa kuti aiswe serura muhomwe, uye zvakare wemagetsi. Muchiitiko chino, mumwe munhu kubva pauduku kuziva nezvengozi hwakazara midziyo yemagetsi. Zvisinei, kurega kubatsira kunoita magetsi simba, mumwe zvimwe hazvifaniri. Kunyanya zvino, apo zvinodiwa SAE kwava makasimba, uye indasitiri rinopa kuchengetedzwa itsva. Pakati pavo, vainyatsotarisirwa inofanira kupiwa anodzivirira namano.

Grounding, automatic, RCD ... chii chinotevera?

Kana vaviri emakore apfuura, kwakajairika zvemagetsi akakumbira nyora hwokugadzira mhinduro zvakagadzirirwa kudzivirira vanhu kubva yemagetsi kuvhunduka, ipapo zvirokwazvo aizopiwa unodzivirira grounding, fiyuzi uye zvakanaka kadikidiki redunhu mudariki. A Pamazita chaigona vaisanganisa nesimba transformer zindoga uye kutarisirwa cheni. Asi kana kugadzirwa zvinogadzirisa izvi zvoga, zvino chii chokuita nemhuri nemagetsi mumatunhu umo grounding redunhu hauna inopiwa nokuda? Machine? Asi kunyange anenge womuenzaniso (class A) kunokonzerwa kana yavose sezvavakatarirwa pari iri kupfuura nenzira kusvika kashanu! With veMubatanidzwa simba musha midziyo yemagetsi mubvunzo akatanga kuudza pakarepo mhinduro. Uye yakawanikwa. Vakatendeukira kuva residual zano kuitika, kana RCD. Kunyange zvazvo zvose zvakafanira kuti parinowanika yagara ichizivikanwa kuti kuunganidza pfungwa uye muvira simbi uye mapurasitiki kugona chete yapfuura. Nokudaro, igumburwe mudziyo inogona kunzi utsva chete ndishushikane.

Kuyeuka mitemo

Sezvo zvinozivikanwa kubva kosi wefizikisi chikoro, kuitika kupfuura kuburikidza muitisi zvinowanisa kumativi pacharwo remagineti. Uyezve, ayo mutsetse umbirimi tenderera. Dzidziso pamusoro vectors pakutsvaga inofamba kuti mhosva zvokutanga inoramba. Ani naani anoda kudzidza zvakawanda nezvayo, unofanira kuverenga nezvekushandiswa kurudyi utongi (kurudyi sikuruu). Kuti tinzwisise kuti kushandisa RCD igumburwe mudziyo, zvakakwana kunzwisisa kuti munda rotates kumativi kondakita uno.

Inotevera pfuma kuti kunokosha akarangarira - a kuitika panowanikwa munhu namahwindo kondakita iyo vayambuke mutsara kutenderera remagineti.

Zviri pamusoro mitemo miviri iyi yakavakirwa residual mudziyo ano.

Design uye inoshanda musimboti

Inside dzimba RCD iri zvikuru toroidal transformer kuitika kuburikidza iyo conductors vari kusiyiwa. Kunze vari kwakaratidzwa pamusoro inouraya nzvimbo.

Anomiririra chimwe danho samambure pamwe conductors maviri - uye razero danho. Izvi pakakoromoka zvaisanganisira residual zano kuitika. Kamwe panzvimbo RCD dunhu pashure magetsi mutoro iri kushandisa, vachishandisa kunotungamirira ano anotanga kuyerera, kukosha zvakatemwa nokuda kutakura. Kunyange pasina leakage (pasi mhosva vasipo), kuti dzenzvimbo mu Pasika kondakita uye razero ndiwo chete (musiyano iri diki). Somugumisiro, wakadenha rinobva minda tenderera oppositely uye offsetting, saka avo geometric mari ndiyo razero. Mangoti pane buri, pane musiyano, uye pave munda. Nekuti rikaitika transformer ano RCD induction. Last, iine simba remagineti dzinokwezva ari chihuri, iyo inobvisa zvechizarira kudzoka mashandiro. The Dunhu runovhuniwa. Akadaro mhinduro anonzi ari differential redunhu mudariki.
