Kukosha uye basa rema "miniature circuit breakers"

Musoro: Kukosha uye basa remadiki ecircuit breakers

suma:

Madiki ecircuit breakers (MCBs)inoita basa guru mukuona kuti masisitimu emagetsi akachengeteka uye akavimbika. Midziyo iyi yava chikamu chakakosha chekuisa magetsi kwemazuva ano, inoshandiswa kudzivirira zvikanganiso zvemagetsi uye kuderedza kukuvara kunogona kuitika. Chinyorwa chino chinoongorora kukosha uye basa rema "compact guards" aya, zvichiratidza kukosha kwawo mumunda weinjiniya yemagetsi.

1. Nzwisisa ma "miniature circuit breakers":

A kadiki kekupwanya dunhu, inowanzo pfupikiswa seMCB, iswichi yemagetsi inongoerekana yagadzirwa kuchengetedza macircuit emagetsi kubva ku overcurrent uye short circuit. Midziyo iyi inowanzoiswa muma switchboard, zvishandiso zvevatengi uye mabhokisi efuse senzira yekutanga yekudzivirira kubva kumatambudziko emagetsi.

2. Zvinhu zvikuru uye zvikamu:

MCBsanozivikanwa nehukuru hwawo hudiki, hunowanzo gara munzvimbo imwe chete mukati me switchboard. Zvisinei, hudiki hwawo hunoratidza kukosha kwawo mukuchengetedza kuchengetedzeka kwemagetsi. Zvikamu zvikuru zveMCBzvinosanganisira mashandiro ekuchinja, ma contacts uye mashandiro ekufamba.

Iyi switch mechanism inobvumira kushanda nemaoko, zvichiita kuti mushandisi akwanise kuvhura kana kuvhara circuit nemaoko. Kune rumwe rutivi, macontacts ane basa rekutungamirira nekukanganisa magetsi ari kufamba mucircuit. Pakupedzisira, trip mechanism inoona overcurrent kana short circuit uye inokonzeraMCBkuvhura dunhu, nokudaro zvichidzivirira sisitimu.

3. Dziviriro yemhepo yakawandisa:

Rimwe remabasa makuru eMCBkudzivirira kuwanda kwemagetsi. Kuwanda kwemagetsi kunoitika kana magetsi akawanda achipfuura simba rawo, izvo zvinogona kukonzera kupisa zvakanyanya uye kukuvara kwezvinhu zvemagetsi.MCBspindura mamiriro ezvinhu aya nekukasika kumisa circuit yemagetsi, nokudaro kudzivirira kupisa zvakanyanya uye kuderedza njodzi yemoto wemagetsi.

4. Dziviriro yedunhu pfupi:

Rimwe basa rakakosha reMCBndeyekudzivirira kupfupika kwemhepo. Kupfupika kwemhepo kunoitika kana kubatana netsaona (kazhinji nekuda kwekusawirirana kwemhepo kana kukundikana kwekudzivirira kupisa) kuchikonzera kuti magetsi akawandisa afambe mudunhu. Kupfupika kwemhepo kunogona kukonzera kukuvara kwakanyanya kumudziyo uye kunogona kutokonzera moto. Nguva yekupindura nekukurumidza yeMCB inoita kuti ikwanise kuona kupfupika kwemhepo uye kumisa kupfupika kwedunhu risati raita kukuvara kukuru.

5. Musiyano nefuse:

Kunyange zvazvo maMCB nemafuse ese ari maviri achidzivirira kubva kumatambudziko emagetsi, pane musiyano mukuru pakati pezviviri izvi. Mafuse ane waya dzakatetepa kana zvidimbu zvesimbi zvinonyunguduka kana magetsi akawandisa, zvichityora circuit. Kana fuse yaputika, inofanira kutsiviwa. Kusiyana neizvi, maMCB haadi kutsiviwa mushure mekugumburwa. Pane kudaro, anogona kugadziriswa zviri nyore mushure mekunge root failure yaongororwa uye yagadziriswa, zvichiita kuti zvive nyore uye zvisadhure zvakanyanya kwenguva refu.

6. Kusarudza uye Kusarura:

Mumagetsi akaomarara umo akawandaMCBsKana zvaiswa muzvikamu zvakatevedzana, pfungwa dzekusarudza nekusarura dzinova dzakakosha. Kusarudza zvinoreva kugona kweMCB kupatsanura dunhu risina kunaka pasina kukanganisa sisitimu yese. Kusiyana, kune rumwe rutivi, kunoita kuti MCB iri pedyo nekutadza itange yatanga, nokudaro ichideredza kukanganiswa pakuiswa. Hunhu uhwu hunobvumira mhinduro yakanangana nekukundikana kwemagetsi, zvichiita kuti mabasa akakosha arambe achienderera mberi uku uchiwana nekugadzirisa chikonzero chikuru chekukundikana.

mhedziso:

Madiki madiki edunhuHapana mubvunzo kuti chikamu chakakosha chezvivakwa zvemagetsi zvemazuva ano. Nekupa dziviriro yemagetsi akawandisa uye mapfupi, maMCB anobatsira kuchengetedza michina, kuderedza kukuvara uye kudzivirira moto wemagetsi. Hukuru hwawo hudiki, nyore kushandisa, uye kugona kudzoreredza mushure merwendo zvinoita kuti ive imwe nzira inodhura pane mafuse echinyakare. Zvakakosha kuyeuka kuti kuisa zvakanaka uye kugadzirisa nguva dzose maMCB kwakakosha kuti pave nehurongwa hwemagetsi hunoshanda uye hwakavimbika. Nekunzwisisa zvinobudirira nekushandisa maminiature circuit breakers, tinogona kuvandudza kuchengetedzeka uye kushanda zvakanaka kwekuisa magetsi.
