Mfundo ndi Ubwino Wotsalira Wa Circuit Breaker (RCBO).
An Mtengo wa RCBOndi mawu achidule a Residual Current Breaker ndi Over-Current.AnMtengo wa RCBOamateteza zipangizo zamagetsi ku mitundu iwiri ya zolakwika;zotsalira zapano komanso zaposachedwa.
Zotsalira zapano, kapena Earth leakge monga momwe zimatchulidwira nthawi zina, ndi pamene pali kusweka kwa dera komwe kungayambitsidwe ndi mawaya olakwika amagetsi kapena ngati waya wadulidwa mwangozi.Kuti mupewe kulondolera komwe kukubwera ndikuyambitsa kugwedezeka kwamagetsi, chowotcha chapano cha RCBO chimayimitsa izi.
Over-Current ndi pamene pali zochulukira chifukwa cha zida zambiri zolumikizidwa kapena pali kagawo kakang'ono mudongosolo.
Zithunzi za RCBOamagwiritsidwa ntchito ngati njira yotetezera kuchepetsa mwayi wovulala ndi ngozi kwa moyo wa munthu ndipo ndi gawo la malamulo omwe alipo omwe amafuna kuti mabwalo amagetsi atetezedwe ku magetsi otsalira.Izi zikutanthauza kuti m'nyumba, RCD idzagwiritsidwa ntchito kukwaniritsa izi osati RCBO chifukwa imakhala yotsika mtengo koma RCD ikayenda, imadula mphamvu kumadera ena onse pamene RCBO imagwira ntchito ya RCD yonse. ndi MCB ndikuwonetsetsa kuti magetsi akupitiliza kuyenda kumadera ena onse omwe sanadutse.Izi zimawapangitsa kukhala ofunikira kwa mabizinesi omwe sangakwanitse kuti magetsi onse azidula chifukwa chakuti wina wadzaza socket ya aa plug (mwachitsanzo).
Zithunzi za RCBOzapangidwa kuti zitsimikizire kuti mabwalo amagetsi akuyenda bwino, zomwe zimayambitsa kulumikizidwa mwachangu pakakhala chotsalira chapano kapena chomwe chapezeka.
Ntchito mfundo yaMtengo wa RCBO
Mtengo wa RCBOamagwira ntchito pa mawaya amoyo a Kircand.Zowona, pompopompo yomwe imayendera kuzungulira kuchokera ku waya wamoyo iyenera kufanana ndi yomwe imadutsa mu waya wosalowerera.
Ngati cholakwika chikachitika, mphamvu yochokera ku waya wosalowerera imachepetsa, ndipo kusiyana pakati pa ziwirizi kumatchedwa Residential Current.Pamene Resident Current imadziwika, makina amagetsi amachititsa RCBO kuchoka pa dera.
Dera loyesa lomwe likuphatikizidwa mu chipangizo chotsalira chapano limatsimikizira kuti kudalirika kwa RCBO kumayesedwa.Mukakankhira batani loyesa, yapano imayamba kuyenda mumayendedwe oyeserera popeza idakhazikitsa kusalinganiza pa koyilo yandale, maulendo a RCBO, ndikuchotsa zolumikizira ndikuwunika kudalirika kwa RCBO.
Ubwino wa RCBO ndi chiyani?
Zonse mu chipangizo chimodzi
M'mbuyomu, akatswiri amagetsi adayikaminiature circuit breaker (MCB)ndi chipangizo chotsalira chamakono mu switchboard yamagetsi.Chotsalira chamagetsi chotsalira chomwe chimagwiritsidwa ntchito kuti chiteteze wogwiritsa ntchito kuti asakumane ndi mafunde owopsa.Mosiyana ndi izi, MCB imateteza mawaya akunyumba kuti asakule.
Ma switchboards ali ndi malo ochepa, ndipo kukhazikitsa zida ziwiri zosiyana zachitetezo chamagetsi nthawi zina kumakhala kovuta.Mwamwayi, asayansi apanga ma RCBO omwe amatha kugwira ntchito ziwiri poteteza waya ndi ogwiritsa ntchito ndikumasula malo mu switchboard popeza ma RCBO amatha kusintha zida ziwiri zosiyana.
Nthawi zambiri, ma RCBO amatha kukhazikitsidwa pakanthawi kochepa.Chifukwa chake, ma RCBO amagwiritsidwa ntchito ndi akatswiri amagetsi omwe amafuna kupewa kuyika ma MCB ndi RCBO breaker.
