KunzwisisaRCCBsuyeMaRCBO: Zvikamu Zvakakosha zveKuchengetedzwa kweMagetsi
Kuchengetedzeka kwakakosha pakuisa magetsi. MaResidual current circuit breakers (RCCBs) nemaResidual current circuit breakers ane overcurrent protection (RCBOs) zvishandiso zviviri zvakakosha zvinoita basa rakakosha pakudzivirira vanhu nepfuma. Kunyange hazvo mashandisirwo azvo akafanana, kunzwisisa mutsauko nemashandisirwo eRCCBs neRCBOs kwakakosha kune chero munhu anoshanda munzvimbo ine magetsi kana yakachengeteka.
Chii chinonzi RCCB?
Chinobvisa magetsi (RCCB) chishandiso chekuchengetedza chakagadzirirwa kudzivirira kuvhunduka kwemagetsi nemoto wemagetsi unokonzerwa nekutadza kwepasi. Chinoshanda nekutarisa kuenzana kwemagetsi ari kuyerera nepawaya dzinopisa nedzisina kusimba. Kana paine kusawirirana kwemagetsi (semuenzaniso, kana mumwe munhu akabata waya inopisa, izvo zvinogona kuratidza kuti magetsi ari kubuda), RCCB inodonha mukati memamirisekonzi mashoma uye inobvisa magetsi. Mhinduro iyi yekukurumidza yakakosha mukudzivirira kukuvara kwakanyanya kana kufa.
MaResidual current circuit breakers (RCCBs) anowanzo shandiswa mu milliamperes (mA) uye anowanikwa mumhando dzakasiyana dze sensitivity levels, dzakadai se30mA yekudzivirira munhu uye 100mA kana 300mA yekudzivirira moto. Anoshandiswa zvakanyanya mumagetsi emudzimba nemabhizimisi kuvandudza kuchengetedzeka, kunyanya munzvimbo dzine mvura, dzakadai sedzimba dzekugezera nekicheni.
Chii chinonzi RCBO?
RCBO (Residual Current Circuit Breaker with Overcurrent Protection) inosanganisa mashandiro eRCCB neminiature circuit breaker (MCB). Izvi zvinoreva kuti RCBO haingodziviriri chete kubva pakukanganisa kwenyika, asiwo inopa dziviriro kubva pakuwanda kwemagetsi uye mapfupi.
Mashandiro maviri eRCBO anoita kuti ive sarudzo inoshanduka-shanduka yekuisa magetsi emazuva ano. Inogona kushandiswa kuchengetedza maseketi ega ega, zvichiita kuti pave nekudzora kwakanyatsojeka uye kuchengetedzeka. Semuenzaniso, kana paine dambudziko paseketi, RCBO inogumburwa, ichiparadzanisa dunhu iroro pasina kukanganisa mamwe maseketi. Chinhu ichi chinobatsira zvikuru munzvimbo dzekugara dzine maseketi akawanda.
Musiyano mukuru pakati peRCCB neRCBO
Kunyange zvazvo maRCCB neRCBOs ese ari maviri akakosha pakuchengetedzwa kwemagetsi, mashandisirwo awo akasiyana zvikuru:
1. Basa: RCCB inopa dziviriro yekukanganisa kwepasi chete, ukuwo RCBO ichipa dziviriro yekukanganisa kwepasi uye dziviriro yekupfuura mwero wemvura.
2.Kushandiswa: MaRCCB anowanzo shandiswa pamwe chete nemaMCB, nepo maRCBO achigona kutsiva zvishandiso zvese, nokudaro zvichiita kuti sisitimu yekudzivirira dunhu ive nyore.
3. Mutengo nenzvimbo: Sezvo maRCBO aine mabasa maviri, anogona kudhura kupfuura maRCCB. Zvisinei, sezvo maRCBO achibatanidza midziyo miviri kuita imwe chete, anogona kuchengetedza nzvimbo mukabati rekuparadzira.
4. Nzira yeKufamba: RCCB inofamba kana kusawirirana kwemagetsi kwaonekwa, nepo RCBO ichifamba kana paine dambudziko repasi uye overcurrent.
Muchidimbu
Muchidimbu, maRCCB neRCBO zvese zvinhu zvakakosha pakuona kuti magetsi akachengeteka. MaRCCB anonyanya kudzivirira kubva pakukanganisa kwevhu, zvichiita kuti ave michina inokosha munzvimbo dzine njodzi huru. Kune rumwe rutivi, maRCBO anobatanidza dziviriro yekukanganisa kwevhu nekudzivirira kwemhepo yakawandisa, zvichipa mhinduro yakakwana kune masisitimu emagetsi emazuva ano.
Pakugadzira kana kuvandudza michina yemagetsi, zvakakosha kufunga nezvezvinodiwa zvakatipoteredza uye mwero unodiwa wekudzivirira. Kunzwisisa mutsauko uye mashandisirwo eRCCBs neRCBOs kunogona kubatsira vanogadzira magetsi nevaridzi vedzimba kuita sarudzo dzakagadzirwa neruzivo dzinovandudza kuchengetedzeka uye kuvimbika kwemagetsi avo. Kunyangwe ukasarudza RCCB kana RCBO, kuisa pamberi kuchengetedzeka kwemagetsi ndiyo sarudzo yakanaka nguva dzose.
