KunzwisisaMCBsuyeRCCBs: Zvikamu Zvakakosha zveKuchengetedzwa kweMagetsi
Kuchengetedzeka kwakakosha zvikuru munyika yekuisa magetsi. MaMinitary circuit breakers (MCBs) nemaResidual current circuit breakers (RCCBs) zvinhu zviviri zvakakosha pakuona kuchengetedzeka kwemagetsi. Midziyo iyi miviri ine mashandisirwo akasiyana asi inowanzo shandiswa pamwe chete kudzivirira zvakakwana kubva kumatambudziko emagetsi. Chinyorwa chino chinoongorora zvakadzama mashandiro, misiyano, uye mashandisirwo emaMinitary circuit breakers (MCBs) nemaResidual current circuit breakers (RCCBs), uye chinosimbisa kukosha kwawo mumagetsi emazuva ano.
Chii chinonzi MCB?
Miniature circuit breaker (MCB) iswitch inongoerekana yashandiswa kudzivirira macircuit emagetsi kubva pakuwanda kwemagetsi uye mashort circuit. Kana magetsi ari kufamba mudunhu akadarika muganho wakatarwa, MCB inodonha uye inodzima magetsi. Izvi zvinodzivirira kupisa zvakanyanya uye njodzi dzemoto dzinokonzerwa nemagetsi akawandisa. Magedhi eMCB anoenderana nekukwanisa kwayo kutakura magetsi, kazhinji pakati pe6A ne63A, uye akagadzirwa kuti ashande nekukurumidza kuderedza kukuvara kwemidziyo netambo.
Madiki ecircuit breakers (MCBs)Zvakakosha mudzimba, mabhizinesi, uye mumaindasitiri. Anowanzo shandiswa muma switchboards kudzivirira macircuit ega ega, zvichiita kuti kutadza kwecircuit kamwe chete kusakanganisa system yese yemagetsi. Maminiature circuit breakers anogona kugadziriswazve, saka magetsi anogona kudzoserwa zviri nyore mushure mekunge dambudziko ragadziriswa, zvichiita kuti ave sarudzo iri nyore yekudzivirira magetsi.
Chii chinonzi RCCB?
Chinobvisa magetsi (RCCB), chinozivikanwawo semudziyo wemagetsi (RCD), chakagadzirirwa kudzivirira zvikanganiso zvepasi uye kuvhunduka kwemagetsi. Chinoona kusawirirana pakati pewaya dziri mhenyu nedzisina kusimba, izvo zvinogona kuitika kana kuvharwa kwemagetsi kwakundikana kana kuti kusangana nezvikamu zviri mhenyu netsaona kunokonzera kuti magetsi adonhe pasi. Kana kusawirirana uku kwaonekwa, RCCB inogumbura uye inobvisa dunhu, zvichideredza zvikuru njodzi yekuvhunduka kwemagetsi nemoto.
MaRCCB anowanikwa mumhando dzakasiyana-siyana dzekudzivirira, kazhinji kubva pa30mA yekudzivirira munhu kusvika pa100mA kana 300mA yekudzivirira michina. Sarudzo yekudzivirira inoenderana nemamiriro ekushandiswa uye huwandu hunodiwa hwekudzivirira. Semuenzaniso, munzvimbo yekugara, 30mA RCCB inowanzo shandiswa kudzivirira vanhu kubva mukuvhunduka kwemagetsi, nepo mumaindasitiri, RCCB ine simba rakawanda inogona kushandiswa kuchengetedza michina.
MCB vs RCCB: Musiyano Mukuru
Kunyange zvazvo ma "miniature circuit breakers" (MCBs) nema "residual current circuit breakers" (RCCBs) akakosha pakuchengetedza magetsi, anoita mabasa akasiyana. Musiyano mukuru uri muzvidziviriro zvavo:
- MCB: Inodzivirira kubva pakuzara kwemagetsi uye kupfupika kwemhepo. Haipe dziviriro kubva pakukanganisa kwepasi kana kuvhunduka kwemagetsi.
- RCCB: Inodzivirira kubva pakukanganiswa kwenyika uye kuvhunduka kwemagetsi. Haipe dziviriro yekupfuura mwero kana yekufambisa mhepo kwenguva pfupi.
Nekuda kwemusiyano uyu, maminiature circuit breakers (MCBs) nemaresidual current circuit breakers (RCCBs) anowanzo shandiswa pamwe chete mukuisa magetsi. Musanganiswa uyu unopa dziviriro yakakwana, zvichiita kuti masisitimu emagetsi nevashandisi vagare vakachengeteka.
Kushandiswa kweMCB neRCCB
Munzvimbo dzekugara, ma "miniature circuit breakers" (MCBs) anowanzo shandiswa kuchengetedza magetsi nemagetsi, nepo ma "residual current circuit breakers" (RCCBs) achiiswa munzvimbo dzine njodzi huru yekubatwa nemagetsi kuti pave nekuchengetedzeka kwakanyanya, senge dzimba dzekugezera nekicheni. Munzvimbo dzemabhizimisi nedzemaindasitiri, zvishandiso zvese izvi zvakakosha pakuchengetedza michina nekuona kuchengetedzeka kwevashandi.
Muchidimbu, ma "miniature circuit breakers" (MCBs) nema "residual current circuit breakers" (RCCBs) chikamu chakakosha che "electrical safety system". Kunzwisisa mashandiro avo uye mashandisirwo azvo kwakakosha kune chero ani zvake ari mukuisa kana kugadzirisa magetsi. Nekubatanidza ma "miniature circuit breakers" (MCBs) nema "residual current circuit breakers" (RCCBs), "safety net" yakasimba inogona kuvakwa kudzivirira njodzi dzakasiyana-siyana dzemagetsi, zvichiita kuti munhu wese ave nenharaunda yakachengeteka.
