KunzwisisaRCD, RCBOuyeRCCB: Zvishandiso zvekuchengetedza zveMagetsi zveBasic
Munyika yekuchengetedzwa kwemagetsi, unowanzo sangana nemashoko akadai seRCD, RCBO neRCCB. Midziyo iyi inoita basa guru mukudzivirira vanhu nepfuma kubva kumatambudziko emagetsi. Kunzwisisa mashandiro ayo, misiyano uye mashandisirwo ayo kwakakosha kune chero munhu ari kuita basa rekuisa kana kugadzirisa magetsi.
Chii chinonzi RCD?
RCD, kana kuti mudziyo wemagetsi unoramba uripo, mudziyo wekuchengetedza wakagadzirirwa kudzivirira kuvhunduka kwemagetsi nemoto wemagetsi unokonzerwa nekutadza kwepasi. Unoshanda nekutarisa nguva dzose magetsi ari kufamba nepakati pesekitori. Kana ukaona kusawirirana pakati pewaya dzinopisa nedzisina kusimba (zvichiratidza kuti magetsi ari kudonhedza mvura pasi), unovhura sekitori mukati memamirisekonzi. Mhinduro iyi inokurumidza inogona kuponesa hupenyu, zvichiita kuti maRCD ave chinhu chakakosha mumagetsi emumba neanotengesa.
MaRCD anowanzo shandiswa mumasekete anopa michina yekunze, dzimba dzekugezera nemakicheni uko njodzi yekubatwa nemagetsi yakanyanya. Anouya mumhando dzakasiyana-siyana, kusanganisira maRCD anotakurika ekuisa kwenguva pfupi uye maRCD akagadziriswa akaiswa mumayuniti evatengi.
Chii chinonzi RCCB?
RCCB, kana kuti residual current circuit breaker, imhando yeRCD. Basa guru reRCCB nderekuona zvikanganiso zvepanyika uye kuvhura circuit kudzivirira kuvhunduka kwemagetsi. Kusiyana nema circuit breakers akajairika anodzivirira kubva pakuzara kwemagetsi uye ma short circuit, maRCCB anotarisa chete pakudzivirira kubuda kwemvura panyika.
MaRCCB anowanzo shandiswa mumagetsi emudzimba nemabhizimisi kuti awedzere kuchengetedzeka. Anowanikwa muzvikamu zvakasiyana, zvichibvumira vashandisi kusarudza mudziyo wakakodzera zvinodiwa pakuisa kwavo magetsi. Kunyange zvazvo maRCCB achipa dziviriro yakanaka kubva pakuvhunduka kwemagetsi, haape dziviriro kubva pakuzara kwemagetsi kana mashort circuits, ndipo panoshanda mimwe michina.
Chii chinonzi RCBO?
RCBO, kana kuti residual current circuit breaker ine dziviriro ye overcurrent, inobatanidza mabasa eRCD ne circuit breaker. Izvi zvinoreva kuti RCBO haingodziviriri chete kubva pakukanganisa kwenyika, asiwo kubva pakuzara kwemagetsi uye ma short circuit. Kushanda uku kunoita kuti RCBO ive sarudzo inoshanduka-shanduka yekuisa magetsi emazuva ano.
MaRCBO anobatsira zvikuru kana nzvimbo iri shoma, sezvo achigona kutsiva RCD necircuit breaker panguva imwe chete. Izvi hazvingorerutsi switchboard chete, asiwo zvinovandudza kuchengetedzeka nekupa dziviriro yakakwana mumudziyo mumwe chete. Akanakira dzimba dzekugara, zvivakwa zvemabhizinesi uye mashandisirwo emaindasitiri.
Misiyano Mikuru
Kunyangwe maRCD, maRCCB neRCBO aine zvinangwa zvakafanana mukuchengetedza magetsi, mabasa avo akasiyana zvikuru:
- RCD: Inonyanya kushandiswa kuona zvikanganiso zvepasi uye kubvisa circuit kudzivirira kuvhunduka kwemagetsi. Haipe dziviriro yekuwedzera simba kana yepfupi circuit.
- RCCB: RCD yakagadzirirwa kuona zvikanganiso zvepasi. Kufanana neRCD, haidziviriri kubva pakuzara kwemagetsi kana mapfupi.
- RCBO: Inobatanidza mashandiro eRCD necircuit breaker kudzivirira zvikanganiso zvepasi uye overloads/short circuits.
Muchidimbu
Muchidimbu, maRCD, maRCCB, uye maRCBO zvishandiso zvakakosha pakuchengetedza magetsi. Kunzwisisa mashandiro avo nekusiyana kwavo kwakakosha pakusarudza dziviriro yakakodzera sisitimu yako yemagetsi. Ungave uri muridzi wemba, nyanzvi yemagetsi, kana maneja wenzvimbo, kunzwisisa zvishandiso izvi kunogona kukubatsira kuita sarudzo dzakachengeteka uye kudzivirira njodzi dzemagetsi. Paunofunga kuisa zvishandiso izvi, gara uchibvunza nyanzvi yemagetsi ine hunyanzvi kuti uve nechokwadi chekutevedzera mitemo yemuno nemitemo.
