Title: Kukosha uye basa reminiature circuit breakers
suma:
Miniature circuit breakers (MCBs)kuita basa rinokosha pakuchengetedza kuchengeteka uye kuvimbika kwemagetsi emagetsi.Midziyo iyi yave chikamu chakakosha chekuiswa kwemagetsi emazuva ano, anoshandiswa kudzivirira kukanganisa kwemagetsi uye kudzikisira kukuvara kunogona kuitika.Ichi chinyorwa chinoongorora kukosha uye kushanda kweaya ma compact guards, achiratidza kukosha kwavo mumunda weinjiniya yemagetsi.
1. Nzwisisa madiki madiki edunhu:
A miniature circuit breaker, kazhinji inodimburirwa seMCB, ishanduko yemagetsi otomatiki yakagadzirirwa kuchengetedza maseketi emagetsi kubva kune overcurrent uye mapfupi maseketi.Zvishandiso izvi zvinowanzoiswa mumabhodhi ekuchinja, zvigadziriso zvevatengi uye mabhokisi efiyusi semutsara wekutanga wekudzivirira kutadza kwemagetsi.
2. Hunhu uye zvikamu:
MCBsvanozivikanwa nehukuru hwavo compact, kazhinji vachigara imwe modular nzvimbo mukati me switchboard.Nekudaro, hukuru hwavo hudiki hunopesana nekukosha kwavo mukuchengetedza kuchengetedzwa kwemagetsi.Zvikamu zvikuru zveMCBsanganisira switch mechanic, mabikirwo uye mafambisirwo erwendo.
Iyo switch mechanic inobvumira kushanda kwemanyorero, ichigonesa mushandisi kuvhura kana kuvhara dunhu.Vanobatika, kune rumwe rutivi, vane basa rekuita uye kukanganisa ikozvino inoyerera kuburikidza nedunhu.Pakupedzisira, nzira yekufamba inoona overcurrent kana dunhu pfupi uye inokonzeresa iyoMCBkuvhura dunhu, nokudaro kudzivirira hurongwa.
3. Overcurrent kudzivirira:
Rimwe remabasa makuru eMCBndiko kudzivirira overcurrent.Overcurrent inoitika kana huwandu hwemazuva ano huchiyerera kuburikidza nedunhu kupfuura huwandu hwayo hwakayerwa, izvo zvinogona kutungamirira mukupisa uye zvinogona kukanganisa kumagetsi emagetsi.MCBspindura kumamiriro ezvinhu aya nekukurumidza kukanganisa dunhu remagetsi, nokudaro kudzivirira kupisa uye kuderedza njodzi yemoto wemagetsi.
4. Kudzivirirwa kwedunhu pfupi:
Rimwe basa rinokosha reMCBndiko kudzivirira pfupi.Dunhu pfupi rinoitika kana kubatana kwetsaona (kazhinji nekuda kwekukanganisa kana kutadza kwekudzivirira) kunokonzera yakawandisa ikozvino kuyerera mudunhu.Dunhu pfupi rinogona kukonzera kukuvadzwa kwakanyanya kune mudziyo uye zvinogona kutokonzera moto.Iyo yekumhanyisa yekupindura nguva yeMCB inoita kuti ione mapfupi maseketi uye kukanganisa dunhu kusati kwaitika kukuvara kukuru.
5. Musiyano nefuse:
Nepo ese maMCB nemafuse achipa dziviriro pakukanganisa kwemagetsi, pane misiyano yakakura pakati pezviviri izvi.Mafusi ane waya dzakatetepa kana zvidimbu zvesimbi zvinonyunguduka kana yakawandisa ikozvino inoyerera, ichipwanya dunhu.Kana fuse ichingovhuvhuta, inoda kutsiviwa.Kusiyana neizvi, maMCB haafanire kutsiviwa mushure mekutsika.Pane kudaro, vanogona kugadziriswa nyore nyore mushure mokunge kukanganisa kwemidzi kwaongororwa uye kugadziriswa, zvichiita kuti zvive nyore uye zvinodhura-zvinobudirira munguva refu.
6. Kusarura uye Kusarura:
In yakaoma magetsi masystem apo akawandaMCBsakaiswa munhevedzano, pfungwa dzekusarudza uye kusarura dzinove dzakakosha.Kusarudzika kunoreva kugona kweMCB kupatsanura dunhu rine mhosva pasina kukanganisa hurongwa hwese.Kusiyanisa, kune rumwe rutivi, kunovimbisa kuti MCB iri pedyo nekukanganisa inofamba kutanga, nokudaro kuderedza kukanganisa mukuiswa.Unhu uhwu hunobvumira mhinduro yakanangwa mukutadza kwemagetsi, kuve nechokwadi chekuenderera kwesevhisi akakosha uchitsvaga nekugadzirisa chikonzero chekutadza.
mukupedzisa:
Miniature circuit breakerspasina mubvunzo chikamu chakakosha chemagetsi emazuva ano.Nekupa overcurrent uye short circuit dziviriro, MCBs anobatsira kuchengetedza midziyo, kuderedza kukuvadzwa uye kudzivirira moto wemagetsi.Saizi yavo yecompact, kureruka kwekushandisa, uye kugona kugadzirisa patsva mushure merwendo kunoita kuti ive imwe inodhura-inoshanda kune echinyakare fuse.Izvo zvakakosha kuyeuka kuti kuisirwa kwakaringana uye kugarogadzirisa kweMCBs kwakakosha kune inoshanda uye yakavimbika system yemagetsi.Nekunyatsonzwisisa uye nekushandisa miniature yedunhu mabreaker, tinogona kuvandudza kuchengetedzeka kwese uye kugona kwekuisa magetsi.
