RCCB MCB: Vimbiso mbiri yemagetsi akachengeteka

KunzwisisaMaRCCB nemaMCB: Zvikamu Zvakakosha zveKuchengetedzwa kweMagetsi

Munyika yekuisa magetsi, kuchengetedzeka kwakakosha zvikuru. Midziyo miviri mikuru inoita basa rakakosha mukuona kuchengetedzeka kwemagetsi iresidual current circuit breakers (RCCBs) uye miniature circuit breakers (MCBs). Kunyange zvazvo ese ari maviri achishandiswa kuchengetedza macircuit emagetsi, anoshanda zvakasiyana uye akagadzirirwa zvinangwa zvakasiyana. Chinyorwa chino chinoongorora zvakadzama mashandiro, misiyano, uye mashandisirwo eRCCBs neMCBs, zvichiratidza kukosha kwazvo mumagetsi emazuva ano.

Chii chinonzi RCCB?

RCCB (Residual Current Circuit Breaker) chishandiso chekuchengetedza chinoona kusarongeka kwemagetsi. Chakagadzirirwa kudzivirira kuvhunduka kwemagetsi uye kuderedza njodzi yemoto wemagetsi unokonzerwa nekutadza kwepasi. RCCB inoramba ichitarisa magetsi ari kufamba nepawaya dzinopisa uye dzisina simba dzedunhu. Kana ikaona musiyano wemagetsi (zvichiratidza kuti mamwe magetsi ari kudonhedza mvura pasi), inogumburwa uye inovhura dunhu mukati memamirisekonzi. Kuita uku nekukurumidza kwakakosha kudzivirira vanhu kubva kuvhunduka kwemagetsi uye kudzivirira njodzi dzinogona kuitika.

MaRCCB anowanzo ongororwa mu milliamperes (mA) uye anowanikwa mumhando dzakasiyana dzekudzivirira, dzakadai se30mA yekudzivirira munhu uye 100mA kana 300mA yekudzivirira moto. Anowanzoshandiswa munzvimbo dzekugara, dzekutengeserana uye dzemaindasitiri, kunyanya kune mvura, senge dzimba dzekugezera nekicheni.

Chii chinonzi MCB?

Kune rumwe rutivi, maMCB (madiki madiki emagetsi anopwanya magetsi), akagadzirirwa kudzivirira macircuit kubva pakuwanda kwemagetsi uye mashort circuit. Kusiyana neRCCBs, dzinotarisa pakuona zvikanganiso zvepasi, maMCBs anotarisa magetsi ari kufamba nepakati pemagetsi. Kana magetsi akadarika simba reMCB, anogumburwa nekudzima magetsi emagetsi kudzivirira kupisa zvakanyanya uye njodzi dzemoto.

MaMCB anoongororwa mu amperes (A) uye anouya mumhando dzakasiyana-siyana, kusanganisira Type B, Type C, uye Type D, akagadzirirwa kutenderera padanho rakasiyana remagetsi. Type B yakakodzera kushandiswa mudzimba, nepo Type C neType D zvichishandiswa munzvimbo dzekutengeserana nemaindasitiri uko kunotarisirwa kuti mafungu emvura apinde zvakanyanya.

Musiyano mukuru pakati peRCCB neMCB

Kunyange zvazvo maRCCB nemaMCB ese ari maviri akakosha pakuchengetedzwa kwemagetsi, ane mabasa akasiyana:

1. Basa: RCCB inoshandiswa kudzivirira kubva pakukanganiswa kwenyika uye kuvhunduka kwemagetsi nepo MCB inoshandiswa kudzivirira kubva pakuzara kwemagetsi uye kupfupika kwemagetsi.

2. Nzira yekuona: RCCB inoona kusawirirana pakati pemafungu aripo nemafungu asina kusimba ukuwo MCB ichitarisa mafungu ese ari kufamba nemudunhu.

3. Mashandisirwo: RCCB inokosha munzvimbo dzine njodzi yekuvhundutswa nemagetsi, nepo MCB ichishandiswa kudzivirira maseketi kubva pakuwanda kwemagetsi.

4. Kunzwa: MaRCCB anonzwa kudonha kwesimba remagetsi madiki, nepo maMCB akagadzirwa kuti agone kubata mazinga esimba remagetsi akakwira asati agumburwa.

Kukosha kwekushandisa RCCB neMCB

Kuti magetsi agare akachengeteka, zvinokurudzirwa kushandisa RCCB neMCB. Musanganiswa uyu unopa dziviriro yakakwana yekudzivirira matambudziko epasi uye overload. Mukushandiswa kwemagetsi kwakajairika, RCCB inogona kuiswa pa switchboard huru kuchengetedza macircuit ese, nepo MCB yakasiyana inogona kushandiswa padunhu rega rega kudzivirira overloads.

Muchidimbu, kunzwisisa basa reRCCBs neMCBs kwakakosha kune chero ani zvake ari mukuisa kana kugadzirisa magetsi. Nekubatanidza zvishandiso izvi zvese mumagetsi, tinogona kuvandudza kuchengetedzeka, kuchengetedza hupenyu, uye kudzivirira kukuvara kwepfuma. Sezvo tekinoroji iri kufambira mberi, kukosha kwemidziyo iyi kucharamba kuchikura, zvichiita kuti ive chikamu chakakosha chekuchengetedzwa kwemagetsi kwemazuva ano.
