Chii chinonzi Circuit Breakers?

Swichi yemagetsi yakagadzirirwa kuchengetedza dunhu remagetsi kuti risakuvara zvinokonzerwa nekuwandisa kwemagetsi/kuwandisa kwemagetsi kana short circuit inozivikanwa secircuit breaker. Basa rayo guru nderekumisa magetsi mushure mekunge ma protective relay aona dambudziko.

Basa reSwitch yeCircuit Breaker.

Chinopwanya dunhu chinoshanda nekuva mudziyo wekuchengetedza nekudaro chinodzivirira kukuvara kwemamota nemawaya kana magetsi achiyerera nepakati pedunhu remagetsi achidarika miganhu yekugadzirwa kwawo. Chinoita izvi nekubvisa magetsi kubva mudunhu kana paine mamiriro asina kuchengetedzeka.

MaDC Circuit Breakers Anoshanda Sei?

Sezvinoratidzwa nezita ravo, ma "Direct Current" (DC) circuit breakers anodzivirira michina yemagetsi inoshanda pa "direct current". Musiyano mukuru pakati pe "direct current" ne "alternating current" ndewekuti "voltage output" muDC inogara iripo. Kusiyana neizvi, "voltage output" mu "Alternating Current" (AC)" inotenderera kakawanda sekondi yega yega.

Chii chinonzi DC Circuit Breaker?

Nheyo dzakafanana dzekudzivirira kupisa uye magnetic dzinoshanda kumaDC breakers sezvinoita kumaAC circuit breakers:
Dziviriro yekupisa inogumbura DC circuit breaker kana magetsi adarika kukosha kwakarongwa. Kupisa kweBimetallic contact kunowedzera uye kunogumbura circuit breaker muchimiro ichi chekudzivirira. Dziviriro yekupisa inoshanda nekukurumidza nekuti magetsi anogadzira kupisa kwakawanda kuti awedzere uye avhure kubatana kwemagetsi sezvo magetsi ari mazhinji. Dziviriro yekupisa yeDC circuit breaker inodzivirira kubva pakuwanda kwemagetsi kwakakwira zvishoma pane magetsi akajairika ekushanda.
Kana paine magetsi ane simba, dziviriro yemagineti inogumbura DC circuit breaker, uye mhinduro yacho inogara iripo ipapo ipapo. Kufanana nemaAC circuit breakers, maDC circuit breakers ane kugona kukuru kwekuputsa kunomiririra magetsi ane simba guru anogona kukanganiswa.
Kumira kwemagetsi kuri kuramba kuchiitwa nemaDC circuit breakers zvinoreva kuti circuit breaker inofanira kuvhura electric contact kure kuti ivhiringidze fault current. Magnetic protection yeDC circuit breaker inodzivirira mashort circuit nemafaults akawanda kupfuura overload.

Mhando nhatu dzeMinitary Circuit Breaker:

Rudzi B (rwendo rwemagetsi rwakapetwa katatu kusvika kashanu).
Rudzi C (rwendo rwemagetsi rwakapetwa ka5-10).
Rudzi D (rwendo rwakapetwa ka10-20 panguva yemagetsi akaongororwa).
