KunzwisisaRCBOZvinhu Zvakakosha Pakuchengetedza Magetsi
Munyika yekuisa magetsi, kuchengetedzeka kwakakosha zvikuru. Chimwe chezvinhu zvakakosha kuti pave nechokwadi chekuti kuchengetedzeka i residual current circuit breaker ine dziviriro ye overcurrent, inozivikanwa seRCBO. Mudziyo uyu unoita basa rakakosha mukudzivirira vanhu nepfuma kubva kumatambudziko emagetsi, zvichiita kuti uve chikamu chakakosha chemagetsi emazuva ano.
Chii chinonzi RCBO?
RCBO musanganiswa wemidziyo miviri inodzivirira: mudziyo wemagetsi unosara (RCD) uye muchina wemagetsi unopwanya magetsi (MCB). Zvikamu zveRCD zvakagadzirirwa kuona zvikanganiso zvepanyika, zvinoitika kana magetsi achiyerera achienda panyika nenzira isingatarisirwi. Zvikanganiso zvepanyika zvinogona kuitika nekuda kwekutadza kupinza, hunyoro kana kusangana netsaona nezvinhu zvipenyu. Kana zvikanganiso zvepanyika zvaonekwa, RCD inovhura dunhu kudzivirira njodzi yekuvhunduka kwemagetsi kana moto.
Kune rumwe rutivi, zvikamu zveMCB zvinodzivirira kubva mumamiriro ekunze akawandisa, ayo anogona kukonzerwa nekuwanda kwemagetsi kana mashort circuits. Kuwanda kwemagetsi kunoitika kana michina yakawanda yakabatana necircuit imwe chete, zvichikonzera kuwanda kwemagetsi kupfuura kwainogona kubata zvakachengeteka. Mashort circuits anoitika kana paine kubatana kwakananga pakati pewaya dzinopisa nedzisina simba, zvichikonzera kuwanda kwemagetsi kamwe kamwe. Mumamiriro ezvinhu aya, MCB inogumburwa nekuvhura circuit, ichidzivirira kukuvara kwewaya nemidziyo.
Sei uchishandisa RCBO?
Kubatanidza mabasa eRCD neMCB mumudziyo mumwe chete kune zvakanakira zvakawanda. Chekutanga, zvinoita kuti kuiswa kwemagetsi kuve nyore. Panzvimbo pekuisa midziyo yakasiyana yekudzivirira dambudziko renyika ne overcurrent, RCBO inopa mabasa ese ari maviri muyuniti imwe chete. Izvi hazvingochengetedzi nzvimbo muyuniti yemutengi chete, asiwo zvinoderedza nguva yekuisa nemutengo.
Chechipiri, maRCBO anowedzera kuchengetedzeka. Kana paine dambudziko remagetsi, maRCBO anokurumidza kudzima circuit, zvichideredza njodzi yemagetsi nemoto. Izvi zvakakosha zvikuru munzvimbo dzekugara, uko kuchengetedzeka kwevanogara kuri chinhu chinonyanya kukosheswa. Pamusoro pezvo, maRCBO anogona kushandiswa mumhando dzakasiyana-siyana, kubva pawaya dzemumba kusvika kumafekitori nemaindasitiri, zvichiita kuti akwanise kushandiswa zvakasiyana-siyana uye kuchinjika.
Kusarudza RCBO chaiyo
Pakusarudza RCBO, zvinhu zvakati wandei zvinofanirwa kufungwa nezvazvo. Chekutanga chiyero chemazuva ano, chinofanira kuenderana nezvinodiwa nemutoro wedunhu. Chiyero chemazuva ano chinowanzo sanganisira 6A, 10A, 16A, 20A uye 32A. Zvakakosha kusarudza RCBO inogona kubata mutoro unotarisirwa pasina kugumburwa zvisina kufanira.
Chimwe chinhu chakakosha i residual current rating, inowanzo ratidzwa mu milliamperes (mA). Standard ratings dzinosanganisira 30mA yekudzivirira munhu uye 100mA kana 300mA yekudzivirira michina. Kune maapplication epamba, 30mA rating inowanzo kurudzirwa kudzivirira kuvhunduka kwemagetsi.
Zvakakoshawo kufunga nezverudzi rweRCBO. Kune mhando dzakasiyana siyana dzekusarudza kubva, dzakadai seAC, A, naB, imwe neimwe yakagadzirirwa kushandiswa kwayo. Rudzi rweAC rwakakodzera macircuit anochinjana, nepo rudzi rweA ruchigona kuona DC ichirira, zvichiita kuti ive yakakodzera macircuit ane zvishandiso zvemagetsi. Rudzi rweB runoshandiswa kumacircuit anogona kunge aine DC yakatsetseka, senge ari muma solar installations.
Muchidimbu
Mukupedzisa, maRCBO mudziyo unokosha zvikuru mumagetsi emazuva ano, anopa dziviriro mbiri kubva pakukanganisa kwepasi uye mamiriro ekunze akawandisa. Dhizaini yavo diki, kuiswa kuri nyore, uye maficha ekuchengetedza akawedzerwa anoita kuti ave sarudzo yepamusoro kune vanogadzira magetsi nevaridzi vedzimba. Sezvo mitemo yekuchengetedza magetsi ichiramba ichichinja, kukosha kwekuisa maRCBO mumidziyo yemagetsi hakugone kupfuudzwa zvakanyanya. Nekunzwisisa nekushandisa chikamu ichi chakakosha, tinogona kuve nechokwadi chekuti nharaunda yakachengeteka kune wese munhu.
