Dzivirira Maseketi Ako: Nzwisisa Basa uye Musiyano weMcb neElcb

Nzwisisa Musiyano Uripo PakatiMCBuyeELCB

Kune avo vasingazive mazwi emagetsi, mazwi ekuti MCB neELCB anonzwika semabhii asina kurongeka. Zvisinei, munyaya dzeinjiniya yemagetsi, mapfupiso aya akakosha zvikuru uye anogona kuita basa guru mukuchengetedza kuchengetedzeka kwemagetsi. Muchinyorwa chino cheblog, tichanyatsoongorora musiyano uripo pakati peMCB neELCB, uye kuti dzinodzivirira sei masisitimu emagetsi nevashandisi.

Ngatitangei tanzwisisa zvinomiririrwa neMCB neELCB. MCB inomiririra miniature circuit breaker uye ELCB inomiririra earth leakage circuit breaker. Midziyo yese yakagadzirwa kuti ipwanye circuit kana paine chikanganiso, asi inoshanda nenzira dzakasiyana zvishoma uye ine mashandisirwo akasiyana.

MCB, sezita rayo, imuchina mudiki wekudzivirira macircuit wakagadzirirwa kudzivirira macircuit kubva pakuwanda kwemagetsi uye ma short circuit. Kana magetsi akawandisa mucircuit, MCB inongoerekana yadonha yobvisa macircuit kuti isakuvadze michina yakabatana kana waya. Izvi zvinoita kuti MCB ive chinhu chakakosha mukudzivirira moto wemagetsi uye kuchengetedza kuchengetedzeka kwevashandisi vemagetsi.

Kune rumwe rutivi, maELCB macircuit breaker akagadzirirwa kudzivirira kubuda kwemvura kana zvikanganiso zvepasi. Anoona kubuda kwemagetsi kudiki kubva kuma conductors ari mupenyu mucircuit kuenda pasi uye anogumbura circuit kana kubuda kwemvura kwakadaro kwaonekwa. Izvi zvakakosha kudzivirira kuvhunduka kwemagetsi kana michina ikakundikana kana waya dzakakuvara.

Imwe yemisiyano mikuru iri pakati peMCB neELCB ndeyekuti dzinoshanda sei. Musimboti wekushanda weMCB ipfungwa yethermal magnetic tripping, iyo inogumburwa kana magetsi akakwira zvakanyanya kana kuti pakaita short circuit. ELCB, kune rumwe rutivi, inoshanda nekuona kusawirirana kwemagetsi pakati pemuchina unofambisa magetsi uri mupenyu nemuchina unofambisa magetsi uri kure. Kana magetsi akabuda, ELCB inogumburwa nedunhu kudzivirira tsaona dzemagetsi.

Panyaya yemashandisirwo ayo, maMCB anowanzo shandiswa kuchengetedza waya dzemagetsi nemidziyo mudzimba, zvivakwa zvemabhizinesi, uye zvivakwa zvemaindasitiri. Ndiyo nzira yekutanga yekudzivirira kubva pakuwanda kwemagetsi uye mashort circuits, zvichiita kuti system yemagetsi nevanhu vese vanoishandisa vagare vakachengeteka. Kune rumwe rutivi, maELCB anowanzo shandiswa kana paine njodzi yakakura yekubuda kwemagetsi, senge maheater emvura, kuiswa kwemagetsi ekunze, kana nzvimbo dzakanyorova.

Mune zvimwe zviitiko, MCB neELCB zvinogona kubatanidzwa kuita chinhu chimwe chete chinonziRCBO(residual current circuit breaker ine dziviriro ye overload). Mudziyo uyu unosanganisa zvakanakira MCB neELCB kuti upe dziviriro ye overload, short circuit uye earth fault. Izvi zvinoita kuti ive mhinduro inoshanda uye yakazara yekuona kuchengetedzeka kwemagetsi mumabasa akasiyana-siyana.

Zvakakosha kuziva kuti kunyange zvazvo MCBs neELCBs zvakakosha pakuchengetedza magetsi, hazvingogumiri panjodzi. Kugara uchigadzirisa uye uchiyedza kwakakosha kuti uve nechokwadi chekuti michina iyi iri kushanda nemazvo. Pamusoro pezvo, zvakakosha kuti iiswe nenyanzvi yemagetsi ine hunyanzvi kuti ive nechokwadi chekuti yakaenzana uye yakaiswa nemazvo zvichienderana nezvinodiwa nehurongwa hwemagetsi.

Muchidimbu, MCB neELCB zvinhu zvakakosha mukuchengetedza kuchengetedzeka kwemagetsi uye kudzivirira tsaona. MCB inodzivirira kubva pakuwanda kwemagetsi uye mashort circuits, ukuwo ELCB inodzivirira kubva pakukanganiswa kwenyika kana kubuda kwemvura. Kunzwisisa musiyano uripo pakati pemidziyo miviri iyi nemabasa ayo kwakakosha pakuchengetedza sisitimu yemagetsi yakachengeteka uye yakavimbika. Ingave yakashandiswa yega kana kuti yakasanganiswa, michina iyi inoita basa rakakosha mukuona kuchengetedzeka kwemidziyo yemagetsi nevanoshandisa magetsi.
