Mamiriro ekushandiswa kweRCCB

Maitiro ekushandisa ma residual current circuit breakers (RCCB) akakosha pakuona kuchengetedzeka kwevanhu nepfuma. Usati watanga kuongorora mamiriro chaiwo ekushandisa, zvakakosha kunzwisisa misimboti yekutanga yekubatidzwa kwemagetsi uye basa reRCCB mukudzivirira kubatidzwa kwemagetsi.

Kuvhunduka kwemagetsi kukuvara kwakakomba kunokonzerwa nekufamba kwemagetsi mumuviri wemunhu. Kana maoko emunhu akabatana newaya inorarama, magetsi anogona kuyerera mumuviri, zvichikonzera kukuvara. Mushure mekuvhunduka kwemagetsi, magetsi anofanira kugurwa nekukurumidza. Nguva yekugumira magetsi inoenderana nehuwandu hwemagetsi ari kuyerera mumuviri. Semuenzaniso, kana magetsi ari 50mA, nguva yekugumira inofanira kunge iri mukati mesekondi imwe chete. Kana magetsi ari 500mA, nguva yekugumira magetsi inopfupikiswa kusvika kumasekonzi 0.1.

A Chinosara cheDunhu reMazuva Ano (RCCB) chishandiso chekuchengetedza magetsi chakagadzirirwa kudzima magetsi otomatiki kana magetsi akabuda kana kuvhunduka kwemagetsi. Kana magetsi asvika padanho rekushanda rakatarwa neswitch yekudzivirira, RCCB inodzima magetsi mukati menguva pfupi kuti ive nechokwadi chekuti vanhu nepfuma zvakachengeteka. Izvi zvinoita kuti RCCB ive chinhu chakakosha chekuchengetedza magetsi mumamiriro akasiyana-siyana ekushandisa.

Maitiro ekushandisa RCCB akasiyana-siyana uye anofukidza zvakasiyana-siyana. Chimwe chezvinhu zvikuru chinosanganisira mitsetse yekugovera michina yemagetsi inobatwa nemaoko uye inofamba, pamwe chete nemidziyo isingachinji iyo vanhu vangasakwanisa kubuda mairi nenguva kana magetsi akabatwa. Pamusoro pezvo, michina yemagetsi munzvimbo dzebasa dzekunze uye macircuit emidziyo yemumba kana socket circuits inofanira kunge yakashongedzwa neRCCBs ine rated residual operating current value isingapfuure 30mA. Izvi zvinoita kuti vanhu vadzivirirwe kubva kunjodzi dzinogona kuitika dzemagetsi munzvimbo idzi.

Imwe nzira yakakosha yekushandisa RCCB ndeye lifti shaft lighting inofambiswa neAC 220V. Muchiitiko ichi, voltage yemagetsi yakakodzera ye lifti shaft lighting i36V. Zvisinei, kana uchishandisa AC 220V, RCCB inofanira kuiswa kuti ipe dziviriro yakawedzerwa. Pamusoro pezvo, chiedza chinofanira kunge chakashongedzerwa nechifukidziro chekudzivirira kuderedza njodzi yekuvhunduka kwemagetsi.

Mukupfupisa, mashandisirwo ema residual current circuit breakers (RCCB) akakosha kudzivirira kuvhunduka kwemagetsi uye kuona kuchengetedzeka kwevanhu nezvinhu. Kubva kumidziyo yemagetsi inobatwa nemaoko uye inofamba kusvika kumasekete emidziyo yemumba uye mwenje weelevator shaft, maRCCB anoita basa rakakosha mukudzivirira mhedzisiro inokuvadza yekuvhunduka kwemagetsi. Nekunzwisisa nekushandisa mashandisirwo akakodzera eRCCB, vanhu nemasangano vanogona kugadzira nharaunda yakachengeteka uye kuderedza njodzi dzetsaona dzemagetsi.
