KunzwisisaRCCBuyeRCBO: 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 kufamba nepawaya dzinopisa nedzisina kusimba. Kana chikaona kusawirirana kwemagetsi, izvo zvinogona kuratidza kudonha kwemagetsi (semuenzaniso, kana mumwe munhu akabata waya inopisa netsaona), RCCB inodonha mukati memamiliseconds 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 kutonga kwakanyatsojeka uye kuchengetedzeka kuve kwakanyatsojeka. Semuenzaniso, kana mudziyo kana seketi ikakanganisika, RCBO inogumburwa, ichibvisa zvikanganiso pasina kukanganisa sisitimu yese yemagetsi. Chinhu ichi chinobatsira zvikuru munzvimbo dzekugara dzine maseketi akawanda.
Musiyano mukuru pakati peRCCB neRCBO
Kunyange zvazvo maRCCB neRCBOs ese ari maviri akakosha pakuchengetedzwa kwemagetsi, ane zvinangwa zvakasiyana:
1. Kudzivirira: RCCB inopa dziviriro yekukanganisa kwenyika chete, nepo RCBO ichipa dziviriro yekukanganisa kwenyika nekupfuura mwero wemvura (overload uye short circuit).
2.Kushandiswa: RCCB inowanzo shandiswa pamwe chete neMCB kupa dziviriro yakakwana, nepo RCBO inogona kushandiswa yakazvimirira kuchengetedza dunhu rimwe chete.
3. Kuisa: Kuisa RCCB neMCB kunotora nzvimbo yakawanda mubhodhi rekugovera, nepo RCBO ichigona kubatanidza mabasa maviri aya kuita mudziyo mumwe chete, nokudaro ichichengetedza nzvimbo.
Kusarudza pakati peRCCB neRCBO
Pakusarudza pakati peRCCB neRCBO, funga nezvezvinodiwa zvemagetsi ako. Kana uchida dziviriro yekutadza kwepasi uye watova neMCB yakaiswa, RCCB inogona kukwana. Zvisinei, pakuisa zvinhu zvitsva kana kuvandudza masisitimu aripo, maRCBO anowanzo kurudzirwa nekuda kwekudzivirira kwawo kwakazara uye dhizaini yekuchengetedza nzvimbo.
Muchidimbu
Muchidimbu, maRCCB neRCBO zvinhu zvakakosha pakuchengetedza magetsi. Kunzwisisa mashandiro avo, misiyano, uye mashandisirwo awo kunogona kukubatsira kuita sarudzo dzakarongeka paunenge uchigadzira kana kuvandudza sisitimu yako yemagetsi. Kunyangwe uri muridzi wemba, nyanzvi yemagetsi, kana nyanzvi yekuchengetedza, kuisa pamberi kushandiswa kwemidziyo iyi kunogona kuderedza zvakanyanya njodzi dzemagetsi, zvichiita kuti nharaunda ive yakachengeteka kune wese munhu.
