Kunzwisisa RCBOMaResidual Current Breakers Asara: Gwaro Rakazara
Munyaya dzekuchengetedza magetsi, RCBO (Residual Current Circuit Breaker with Overcurrent Protection) chinhu chakakosha mumidziyo yemagetsi yemazuva ano. Mudziyo uyu unobatanidza mabasa emudziyo wemagetsi unoramba uripo (RCD) neminiature circuit breaker (MCB) kuti upe dziviriro mbiri kubva pazvikanganiso zvepasi nemamiriro ekunze. Muchinyorwa chino, tichanyatsoongorora mashandiro, zvakanakira uye mashandisirwo eRCBO residual current circuit breakers.
Chii chinonzi RCBO?
MaRCBO akagadzirirwa kuchengetedza maseketi kubva kunjodzi mbiri huru: zvikanganiso zvepasi uye kuwanda kwemagetsi. Kutadza kwepasi kunoitika kana magetsi achiyerera pasi nenzira isingatarisirwi, izvo zvinogona kukonzera kuvhunduka kwemagetsi kana moto. Kutadza kwemagetsi, kune rumwe rutivi, kunoitika kana magetsi achipfuura simba reseketi, izvo zvinogona kukonzera kupisa kwakanyanya uye kukuvadza michina yemagetsi.
Iyo RCBO inogara ichitarisa magetsi ari kufamba nemudunhu. Kana ikaona kusawirirana pakati pewaya dzinopisa nedzisina kusimba (dzinozivikanwa se leakage current), inogumburwa yovhura dunhu. Panguva imwe chete, iyo RCBO inogumburwawo kana magetsi akadarika muganho wakatarwa, ichiva nechokwadi chekuti dunhu rakachengetedzwa kubva kumarudzi ese ezvikanganiso.
Zvinhu zvikuru zveRCBO
1. Dziviriro Kaviri: Chinhu chikuru cheRCBO ndechekuti inopa dziviriro yemagetsi yasara uye dziviriro yemagetsi akawandisa mumudziyo mumwe chete. Izvi zvinobvisa kudiwa kwemaRCD nemaMCB akasiyana, nokudaro zvichiita kuti hurongwa hwemagetsi huve nyore.
2. Dhizaini Yakabatana: MaRCBO anowanzova madiki pane kushandisa zvishandiso zvakasiyana uye anogona kuiswa zviri nyore mumayuniti evatengi nemabhodhi ekuparadzira. Izvi zvinobatsira zvikuru munzvimbo dzekugara nedzekutengeserana uko nzvimbo iri shoma.
3. Kukanda Magiya Pakusarudza: MaRCBO mazhinji akagadzirwa kuti abvumire kukanda magiya pakusarudza, zvinoreva kuti dunhu rakakanganiswa chete ndiro richadamburwa kana paine zvikanganiso. Izvi zvinowedzera kuvimbika kwehurongwa hwemagetsi uye zvinoderedza kukanganiswa kwemamwe magiya.
4. Kunzwa Kunogona Kugadziriswa: MaRCBO anowanikwa mumhando dzakasiyana dzekudzivirira, kazhinji kubva pa30mA yekudzivirira munhu kusvika pa100mA kana 300mA yekudzivirira michina. Kuchinjika uku kunoita kuti dziviriro ienderane nezvinodiwa zvekuisa.
Kushandiswa kweRCBO
RCBO inoshandiswa zvakanyanya mumhando dzakasiyana siyana, kusanganisira:
- Kuisa Dzimba: Varidzi vedzimba vanogona kubatsirwa nekuchengetedzeka kwakawedzerwa kunopihwa neRCBOs, kudzivirira kuvhunduka kwemagetsi uye kudzivirira kukuvara kwemidziyo yemumba.
- Zvivako zveMabhizinesi: Munzvimbo dzekutengeserana, maRCBO anogona kuderedza njodzi yezviitiko zvemagetsi, zvichibatsira kuona kuchengetedzeka kwevashandi nevatengi.
- Nzvimbo Yemaindasitiri: Mukushandiswa kwemaindasitiri, michina yemakanika inowanzo sangana nemamiriro ezvinhu akaoma, uye RCBO inogona kupa dziviriro yakavimbika kubva kumatambudziko emagetsi.
Muchidimbu
RCBO residual current circuit breaker chishandiso chakakosha chekuona kuchengetedzeka kwemagetsi munzvimbo dzekugara nedzekutengeserana. Nekubatanidza mashandiro eRCD neMCB, inopa dziviriro yakakwana kubva pakukanganisa kwepasi nemamiriro ekunze. Nekugadzirwa kwayo kwakabatana, kugona kusarudza kudonha, uye kunzwisisika kunogadziriswa, RCBO mhinduro inoshanda zvakasiyana-siyana yekuisa magetsi emazuva ano. Sezvatinoramba tichikoshesa kuchengetedzeka kwemasisitimu edu emagetsi, kunzwisisa nekushandisa zvishandiso zvakaita seRCBOs kwakakosha kudzivirira njodzi dzemagetsi uye kuve nerunyararo rwepfungwa.
