Kutonga uye kurapwa kwemutsigiri wedunhu "kuvhara kwenhema"

Kana iyocircuit breakerinovhara otomatiki isina oparesheni, imhosva "kuvhara kwenhema".Kazhinji, inofanira kutongwa sezvinotevera.Mushure mekuongorora, zvinosimbiswa kuti kushanda hakuna kuvharwa.Kana mubato uri munzvimbo ye "kumashure" uye chiedza chitsvuku chinoramba chichipenya, chinoratidza kuticircuit breakeryakavharwa, asi "zvisizvo kuvhara".Muchiitiko ichi, vhura iyocircuit breaker.

Kune "zvisizvo"circuit breaker, kana muvharidzi wedunhu akazarurwa uye ipapo "asina kururama", inofanira kubviswa pavhavha yekuvhara, chengetedza zvikonzero zvemagetsi uye zvemagetsi maererano, uye taura nekutumira kuti umise mhepo inoputika uye ushandure kugadzirisa.Zvikonzero zve "kusawirirana" zvinogona kusanganisira:

1. Mapoinzi maviri akanaka uye asina kunaka mudunhu reDC akatsikwa kuita kuti dhizaini yekuvhara yekuvhara yakabatana.

2, otomatiki kudzoreredza relay chikamu chinokanganisa chakabatana chinodzora loop (senge yemukati nguva relay kazhinji yakavhurika kuonana yakavharwa zvisizvo), kuitira kuti wedunhu avhare.

3, iyo yekuvhara yekubatisa coil kuramba idiki, uye yekutanga voltage yakadzikira, kana iyo DC system pulse ikaitika ipapo, ichaita kuti muparadzi wedunhu avhare nekukanganisa.

Mamiriro e "kuramba kuvhara" anoitika zvakanyanya mukuita kwekuvhara kushanda nekuvhara zvakare.Semuenzaniso, kana muparadzi wedunhu remagetsi akamira achiramba kuvhara, njodzi yacho ichawedzera.Inogona kukamurwa kuita matanho matatu ekuona chikonzero uye kurapwa kwemutsindo wedunhu "kurambwa".

1) Tarisa kana kuramba kwekare kuvhara kunokonzerwa nekushanda kusina kunaka (zvakadai sekugadzirisa kushandura kuregedza kuenda nekukurumidza), uye shandisa shanduko yekudzora kuti ubatanidze zvakare.

2) Kana kuvhara kuchiri kubudirira, tarisa zvikamu zvose zvemagetsi emagetsi kuti uone kana pane kukanganisa mumagetsi emagetsi.Chengetedza zvinhu ndezvi: kuvhara kudzora simba rekupa kwakajairika;Kana iyo yekuvhara yekudzora yedunhu fuse uye yekuvhara yedunhu fuse iri mumamiriro akanaka;Kunyangwe kusangana kwekuvhara contactor kwakajairika;Chinja chinja chekudzora kune chinzvimbo che "kuvhara" kuti uone kana iyo yekuvhara simbi yepakati chiitiko chakajairika.

3) Kana dunhu remagetsi rakajairika uye muparadzi wedunhu achiri kugona kuvharwa, zvinoratidza kuti pane kukanganisa kwemagetsi.Muparadzi wedunhu anofanirwa kumiswa uye kuziviswa kune kurongwa kwekugadzirisa uye kurapwa.
