KunzwisisaRCBO Residual Current Circuit Breakers: Gwaro Rakazara
Munyaya dzekuchengetedzwa kwemagetsi,MaRCBO (mareside current breakers ane dziviriro ye overcurrent)Zvinhu zvakakosha mumidziyo yemagetsi yemazuva ano. Zvinosanganisa mashandiro emidziyo yemagetsi yasara (RCDs) nemaminiature circuit breakers (MCBs), zvichipa dziviriro mbiri kubva pazvikanganiso zvepasi uye mamiriro ekunze akawandisa. Chinyorwa chino chichaongorora misimboti yekushanda, zvakanakira, uye mashandisirwo eRCBOs.
Chii chinonzi RCBO?
MaRCBO akagadzirirwa kuchengetedza macircuit emagetsi kubva kunjodzi mbiri huru: zvikanganiso zvepasi uye kuwandisa kwemagetsi. Kukanganisika kwepasi kunoitika kana magetsi achiyerera pasi nenzira isingatarisirwi, zvichikonzera kuvhunduka kwemagetsi kana moto. Kuwanda kwemagetsi, kune rumwe rutivi, kunoitika kana magetsi achiyerera nepakati pedunhu achipfuura simba rawo, zvichikonzera kupisa zvakanyanya uye kukuvadza midziyo yemagetsi.
Iyo RCBO inogara ichitarisa magetsi ari kufamba nemudunhu. Kana ikaona kusawirirana pakati pema conductors anopisa neasina kusimba (kureva, magetsi anobuda), inodonha nekudzima magetsi mudunhu. Inodonhawo kana magetsi akadarika muganho wakatarwa, ichidzivirira magetsi kubva kumarudzi ese ari maviri ezvikanganiso.
Zvinhu zvikuru zveRCBO
1. Dziviriro Iviri: Chinhu chikuru chinobatsira RCBO kugona kwayo kupa dziviriro yemagetsi akasara pamwe nedziviriro yemagetsi akawandisa mumudziyo mumwe chete. Izvi zvinobvisa kudiwa kwemaRCD nemaMCB akasiyana, nokudaro zvichiita kuti hurongwa hwemagetsi huve nyore.
2. Dhizaini Yakamanikana: MaRCBO anowanzova madiki pane kushandisa zvishandiso zvakasiyana, zvichibvumira kushandiswa kwakanaka kwenzvimbo mumayuniti evatengi kana mabhodhi ekuparadzira.
3. Kusarudza Kutsika: MaRCBO mazhinji akagadzirwa nekusarudza kudonha, zvichireva kuti kana paine chikanganiso, dunhu rakakanganiswa chete ndiro richabviswa. Chinhu ichi chinowedzera kuvimbika kwehurongwa hwemagetsi uye chinoderedza kukanganiswa nemamwe matunhu.
4. Kunzwisisa Kunogona Kugadziriswa: MaRCBO anopa mazinga akasiyana-siyana ekudzivirira, anowanzo tangira pa30mA yekudzivirira munhu kusvika pa100mA kana 300mA yekudzivirira michina. Kuchinjika uku kunobvumira chirongwa chekudzivirira kuti chigadziriswe zvinoenderana nezvinodiwa zvekuisa.
Kushandiswa kweRCBO
MaRCBO anoshandiswa zvakanyanya munzvimbo dzekugara, dzemabhizinesi, uye dzemaindasitiri. Mudzimba, anowanzoiswa mumidziyo yemagetsi kudzivirira maseketi anofambisa midziyo yakakosha senge mafiriji, michina yekuwachisa, uye masisitimu ekudziyisa. Muzvivakwa zvemabhizinesi, maRCBO akakosha pakudzivirira midziyo inobatwa nenjodzi uye kuona kuchengetedzeka kwevashandi nevatengi.
Mukushandiswa kwemaindasitiri, maRCBO anoshandiswa mumichina inoda kuchengetedzwa kwepasi uye kuchengetedzwa kwehuwandu hwezvinhu. Dziviriro yavo yakavimbika inobatsira kudzivirira kukuvara kwemidziyo uye nguva inodhura yekushanda.
Muchidimbu
Midziyo yeRCBO residual current devices (RCBOs) inokosha pakuchengetedza magetsi munzvimbo dzese. Inobatanidza mashandiro eRCDs neMCBs, ichipa dziviriro yakakwana yekudzivirira pasi uye overcurrent. Nedziviriro mbiri, dhizaini diki, kukanganiswa kwakasarudzwa, uye kunzwisisika kunogadziriswa, maRCBOs mhinduro inoshanda zvakasiyana-siyana yekuisa magetsi emazuva ano. Sezvo kuchengetedzeka kwemagetsi kuri chinhu chakakosha, kunzwisisa nekushandisa maRCBOs kwakakosha pakuchengetedza hupenyu nepfuma. Ingave munzvimbo dzekugara, dzebhizinesi, kana dzemaindasitiri, maRCBOs akakosha pakuchengetedza magetsi.
