Kodi RCBO ndi chiyani ndipo imagwira ntchito bwanji?

Mtengo wa RCBOndi chidule cha "otsalira otsalira panopa dera breaker" ndipo ndi yofunika magetsi chitetezo chipangizo kuphatikiza ntchito za MCB (kang'ono dera wosweka) ndi RCD (zotsalira panopa chipangizo). Amapereka chitetezo ku mitundu iwiri ya zolakwika zamagetsi: overcurrent and residual current (yotchedwanso leakage current).

Kuti mumvetse mmeneMtengo wa RCBOimagwira ntchito, tiyeni tikambirane mwachangu mitundu iwiriyi ya zolephera.

Overcurrent imachitika pamene madzi ambiri akuyenda mozungulira, zomwe zingayambitse kutentha kwambiri komanso mwina ngakhale moto. Izi zikhoza kuchitika pazifukwa zosiyanasiyana, monga chigawo chachifupi, kuchuluka kwa dera, kapena vuto lamagetsi. Ma MCB amapangidwa kuti azindikire ndi kusokoneza zolakwika zomwe zimachitika mopitilira muyeso mwa kupotoza dera nthawi yomweyo pomwe magetsi apitilira malire omwe adakonzedweratu.

Kumbali ina, zotsalira zapano kapena kutayikira kumachitika pamene dera lidasokonekera mwangozi chifukwa cha waya woyipa kapena ngozi ya DIY. Mwachitsanzo, mukhoza kuboola chingwe mwangozi pamene mukuyika mbedza ya chithunzi kapena kudula ndi makina otchetcha udzu. Pamenepa, mphamvu yamagetsi imatha kutayikira pamalo ozungulira, zomwe zitha kuyambitsa kugwedezeka kwamagetsi kapena moto. Ma RCD, omwe amadziwikanso kuti GFCIs (Ground Fault Circuit Interrupters) m'maiko ena, adapangidwa kuti azitha kuzindikira mwachangu ngakhale mphindi zochepa zomwe zikutuluka ndikuyendetsa dera mkati mwa ma milliseconds kuti apewe vuto lililonse.

Tsopano, tiyeni tiwone mwatsatanetsatane momwe RCBO imaphatikizira kuthekera kwa MCB ndi RCD. RCBO, monga MCB, imayikidwa mu switchboard kapena gawo la ogula. Ili ndi gawo la RCD lopangidwa lomwe limayang'anira mosalekeza zomwe zikuyenda kuzungulira dera.

Kuwonongeka kopitilira muyeso kumachitika, gawo la RCBO's MCB limazindikira kuchuluka kwamagetsi ndikuyendetsa dera, motero imasokoneza magetsi ndikuletsa ngozi iliyonse yokhudzana ndi kuchulukira kapena kuzungulira kwafupi. Nthawi yomweyo, gawo la RCD lomwe limamangidwa limayang'anira momwe mawaya amoyo amakhalira komanso osalowerera ndale.

Ngati chotsalira chilichonse chapezeka (chowonetsa vuto lakutayikira), chinthu cha RCBO's RCD nthawi yomweyo chimayendetsa dera, motero imadula magetsi. Kuyankha kofulumira kumeneku kumatsimikizira kuti kugwedezeka kwa magetsi kumapewedwa ndipo moto womwe ungakhalepo umatetezedwa, kuchepetsa chiopsezo cha zolakwika za mawaya kapena kuwonongeka kwa chingwe mwangozi.

Ndizofunikira kudziwa kuti RCBO imapereka chitetezo chamtundu uliwonse, kutanthauza kuti imateteza mabwalo apadera mnyumba yomwe ili yodziyimira pawokha, monga mabwalo owunikira kapena malo ogulitsira. Chitetezo chokhazikikachi chimathandizira kuzindikira zolakwika ndikudzipatula, kuchepetsa kukhudzidwa kwa mabwalo ena pakachitika cholakwika.

Mwachidule, RCBO (overcurrent residual current circuit breaker) ndi chida chofunikira pachitetezo chamagetsi chomwe chimagwirizanitsa ntchito za MCB ndi RCD. Imakhala ndi zolakwika zambiri komanso ntchito zotsalira zachitetezo kuti zitsimikizire chitetezo chamunthu komanso kupewa ngozi zamoto. Ma RCBO amatenga gawo lofunikira pakusunga chitetezo chamagetsi m'nyumba, nyumba zamalonda ndi malo opangira mafakitale podumpha mwachangu mabwalo akapezeka kuti pali vuto.
