Macircuit Breakers: Kunzwisisa Kukosha Kwawo MuMasisitimu Emagetsi

Muminda yeinjiniya yemagetsi nekuchengetedza, izwi rekuti "circuit breaker" rinokosha zvikuru. Circuit breaker iswitch yemagetsi inongoerekana yagadzirwa kudzivirira macircuit kubva mukukuvadzwa kunokonzerwa nekuwanda kwemagetsi kana mashort circuit. Basa rayo guru nderekukanganisa magetsi kana paine chikanganiso, nokudaro kudzivirira njodzi dzinogona kuitika dzakadai semoto wemagetsi kana kukuvara kwemidziyo. Chinyorwa chino chichaongorora zvinhu zvakasiyana-siyana zvemacircuit breaker, kusanganisira mhando dzawo, mabasa awo, uye basa rawo guru mumagetsi emazuva ano.

Chii chinonziwo circuit breaker?

Chinopwanya dunhu, chinozivikanwawo sechinopwanya magneto-thermal, chinhu chakakosha mukuisa magetsi emazuva ano.

Mabasa eVapambi veDunhu

Basa guru remuchina wekupwanya magetsi nderekuchengetedza magetsi kuti aone magetsi ari mudunhu. Kana magetsi adarika mwero wakatarwa, muchina wekupwanya magetsi unodonha, wobva wadzima magetsi. Izvi hazvingodziviriri chete tambo nemidziyo yakabatana asiwo zvinoita kuti vanhu vanogona kubatwa nemagetsi vagare vakachengeteka.

Kune nzira mbiri huru dzekushandisa macircuit breakers:kupisauyemagineti. Ma "thermal circuit breakers" anoshandisa bimetallic strips; kana magetsi akanyanya kukwira, bimetallic strip inopisa uye inokotama, zvichiita kuti "circuit breaker" igumbuke. Ma "magnetic circuit breakers" anoshandisa ma "electromagnets"; kana magetsi adarika mwero wakati, ma "electromagnet" anobatana, zvichiita kuti "circuit breaker" igumbuke. Mamwe ma "circuit breakers" emazuva ano anosanganisa nzira dzese dziri mbiri kuti dzivandudze mashandiro ekudzivirira.

Mhando dzeVapanduki veDunhu

Macircuit breaker anouya mumhando dzakasiyana-siyana, imwe neimwe yakagadzirirwa mashandisirwo chaiwo uye nharaunda. Mhando dzakajairika dzinosanganisira:

1. Madiki eChikamu Chinopwanya (MCB):Maminiature circuit breaker anoshandiswa zvakanyanya munzvimbo dzekugara nedzekutengeserana kudzivirira kuwandisa kwemagetsi uye mashort circuit. Madiki uye ari nyore kuisa mumabhokisi ekuparadzira.
2. Chinopwanya Dunhu Remagetsi Rinosara (RCCB):Ichi chishandiso chinozivikanwawo seRCD, chinodzivirira kuvhunduka kwemagetsi nekuona kusawirirana kwemagetsi. Kana paine chikanganiso, senge munhu akabata waya inorarama, RCCB inogumburwa, yodzima simba remagetsi.
3. MaMolded Case Circuit Breakers (MCCBs): Macircuit breakers aya anoshandiswa mumaindasitiri uye anokwanisa kubata ma currents akakwira. MaMCCB anopa dziviriro ye overload, short-circuit, uye ground fault.
4. MaAir Circuit Breaker (ACBs): MaAir circuit breaker anowanzo shandiswa mumashandisirwo emagetsi ane simba guru uye akagadzirirwa kumisa mafungu makuru. Anowanzo wanikwa muzviteshi zvemagetsi uye mumaindasitiri makuru.
5. Madhiraivha eMagineti eHydraulic Magnetic Circuit:Macircuit breaker aya anoshandisa nzira dze hydraulic kuti agumbuke, zvichipa mhinduro yakavimbika kumashandisirwo emagetsi ane simba guru.

Kukosha kwema "circuit breakers"

Kukosha kwemacircuit breaker hakugoni kurerutswa. Izvi zvinhu zvakakosha zvinovimbisa kushanda kwakachengeteka uye kwakavimbika kwemasystem emagetsi. Nekudzivirira kuwanda kwemacircuit circuit uye mashort circuit breaker, macircuit breaker anobatsira kuderedza njodzi yemoto wemagetsi, kukuvara kwemidziyo, uye kukuvara kwemunhu. Uyezve, kana paine chikanganiso, macircuit breaker anogona kugadziriswa nekukurumidza uye zviri nyore, nokudaro achivandudza kushanda zvakanaka kwesystem yemagetsi.

Kuwedzera pamabasa avo ekudzivirira, macircuit breaker anoita basa rakakosha mukutevedzera mitemo yemagetsi. Matunhu mazhinji anoda kuti macircuit breaker aiswe muzvivakwa zvekugara uye zvemabhizinesi kuitira kuti pave nekuchengetedzeka uye kuvimbika.

Muchidimbu

Muchidimbu, macircuit breaker zvishandiso zvakakosha mumunda weinjiniya yemagetsi. Anodzivirira macircuit kubva pakuwanda kwemagetsi uye mashort circuit, zvichiita kuti ave akakosha pakuchengetedza nharaunda dzekugara nedzemaindasitiri. Sezvo tekinoroji ichifambira mberi, macircuit breaker ari kuramba achichinja kuti ape dziviriro yepamusoro uye kushanda zvakanaka. Kunzwisisa mhando dzakasiyana dzemacircuit breaker nemabasa awo kwakakosha kune chero munhu anoshanda mumunda wemagetsi, sezvo zvichiita kuti masisitimu emagetsi ashande zvakachengeteka uye zvinobudirira. Ingave mudzimba, mumahofisi, kana mumafekitori, macircuit breaker anoramba ari chikamu chakakosha chezvivakwa zvemagetsi zvemazuva ano.
