Chinopwanya Dunhu Rinobuda: Kushandisa Tekinoroji Yekudzivirira Magetsi Yepamusoro Kuve nechokwadi Chekuchengetedzwa Kwehupenyu Nepfuma

Mudziyo wedunhu unodonha: chengetedza kuchengetedzeka kwemagetsi

Chinopwanya dunhu chinobuda mvura, chinozivikanwawo sechinodzora dunhu remagetsi chinosara (RCD)), chinhu chakakosha muhurongwa hwemagetsi uye chinoita basa guru mukuona kuti vanhu nezvinhu zvavo zvakachengeteka. Mudziyo uyu wakagadzirirwa kudzivirira njodzi yekuvhunduka kwemagetsi uye moto wemagetsi unokonzerwa nekubuda kwemvura. Muchinyorwa chino, tichaongorora kukosha kwema "earth leakage circuit breakers", mabasa awo uye zvazvinoreva pakuisa ma "earth leakage circuit breakers" munzvimbo dzakasiyana-siyana.

Basa guru rechinhu chinopwanya magetsi che earth leakage nderekutarisa magetsi ari kufamba nepakati pe circuit. Chakagadzirirwa kuona kusawirirana pakati pema conductors ari mupenyu neasina kusimba anogona kuitika nekuda kwekutadza kushanda kwemagetsi kana nzira dzepasi dzisina tsaona. Kana kusawirirana uku kwaonekwa, chinhu chinopwanya magetsi che residual current chinokurumidza kukanganisa kufamba kwemagetsi, zvichidzivirira kukuvara kunogona kuitika.

Chimwe chezvakanakira zvikuru zvema "earth leakage circuit breakers" kugona kwawo kudzivirira kubva pakuvhunduka kwemagetsi. Kana paine dambudziko, senge kana munhu akasangana ne "live conductor", "residual current breaker" inopindura nekudzima magetsi, zvichideredza njodzi yekukuvara kana kufa. Izvi zvinonyanya kukosha munzvimbo dzekugara, dzebhizinesi, uye dzemaindasitiri uko zviitiko zvemagetsi zvinogona kuva nemigumisiro yakakomba.

Pamusoro pezvo, ma "earth leakage circuit breakers" anobatsira kuderedza mukana wemoto wemagetsi. Nekukurumidzira kubvisa magetsi kana paine chikanganiso, zvishandiso izvi zvinobatsira kudzivirira kupisa zvakanyanya uye kupwanyika, izvo zvinowanzo kukonzera moto mumagetsi. Maitiro aya ekuchengetedza anogona kuderedza zvakanyanya mukana wekukuvara kwepfuma nekurasikirwa.

Mitemo nemirau yekuchengetedzwa kwemagetsi munyika dzakawanda inorayira kuiswa kwema residual current circuit breakers. Muzvivakwa zvekugara zvinowanzodiwa munzvimbo dzakadai sekicheni, dzimba dzekugezera uye masoketi ekunze uko njodzi yehunyoro uye kuva pedyo nemvura zvinowedzera mukana wekudonha kwemvura. Munzvimbo dzekutengeserana nemaindasitiri, ma earth leakage circuit breakers akakosha pakudzivirira vanhu nemidziyo kubva kunjodzi dzemagetsi.

Zvakakosha kuziva kuti kune mhando dzakasiyana dzema earth leakage circuit breakers, kusanganisira ma fixed, portable uye socket-type RCDs, uye mhando yega yega yakagadzirirwa kushandiswa kwayo. Pamusoro pezvo, kune mhando dzakadai seType AC, Type A uye Type B RCDs, dzinopa mazinga akasiyana ekudzivirira uye dziviriro kubva kuma fault currents akasiyana-siyana. Kusarudza mhando chaiyo ye residual current circuit breaker kwakakosha pakuona dziviriro yakazara yemagetsi akapihwa.

Kuongororwa nguva dzose nekugadzirisa ma residual current circuit breakers kwakakosha kuti vaone kuti anoshanda zvakanaka. Kuongororwa nguva dzose kunobatsira kuona kuti michina inogona kupindura zvikanganiso zvekubuda kwemvura uye kukwanisa kumisa magetsi kana zvichidikanwa. Pamusoro pezvo, kugadziriswa nekuongororwa kunoitwa nenyanzvi dzakanyatsokodzera kunodiwa kuti vaone nekugadzirisa matambudziko angangoitika anogona kukanganisa kushanda kwe residual current circuit breaker.

Muchidimbu, chinhu chinopwanya maburi chinobuda mvura mumagetsi chinhu chakakosha mumagetsi uye inzira inokosha yekudzivirira kuvhunduka kwemagetsi nemoto wemagetsi. Kugona kwavo kuona nekupindura kana mvura yabuda kwakakosha pakuchengetedza hupenyu nepfuma. Nekutevedzera mitemo yekuchengetedza uye kuona kuti zvinhu zviri kuiswa zvakanaka, kushandiswa kwakawanda kwechinhu chinopwanya maburi chinobuda mvura mumagetsi kunobatsira kupa nzvimbo yakachengeteka yemagetsi kune wese munhu.
