Umehluko phakathi kwama-circuit breaker nokunqamula amaswishi

Ama-Ama-Circuit breakersfuthi izinqamuli zingaphazamisa amasekhethi womabili. Ngokuya ngenani lezigxobo, zingasebenza kumasekhethi esigaba esisodwa noma sezigaba ezintathu. Umsebenzi we-circuit breaker ukuvikela isifunda kanye nemishini. Ivamise ukuba nesici sokugibela esizenzakalelayo futhi ingasebenza ngomthwalo. Ngenkathi isinqamuli sisetshenziswa kuphela ukuphazamisa isekethe. Ngokuvamile ayinqamuli ngokuzenzakalelayo isekethe futhi ayikwazi ukusebenza ngomthwalo. Lesi sihloko, ngokuhlanganisa imisebenzi nokuhlukaniswa kwama-circuit breaker kanye nezinqamuli, sethula kabanzi umehluko phakathi kwabo.

I-low-voltage circuit breaker

1. Umsebenzi we-circuit breaker

Ukuvikelwa kokulayisha ngokweqile: Uma i-current in circuit idlula imanje elilinganiselwe isikhathi esithile, isinqamuli sesifunda sizosinqamula ngokuzenzakalelayo isekethe. Isibonelo, uma isokhethi ixhunywe nezinto zikagesi ezinamandla amaningi kakhulu futhi i-current igcwala ngokweqile, i-circuit breaker izokhubeka ukuze ivimbele isekethe ukuthi ingalimali ngenxa yokushisa ngokweqile ngisho nokugwema ukudala umlilo.

2. Ukuvikelwa kwesekethe emfishane: Uma isifunda esifushane senzeka kusekethe, okusho ukuthi i-current iba phezulu kakhulu ngokuzumayo, i-breaker circuit inganqamula ngokushesha isekethe. Lokhu kuvimbela umsinga omkhulu owenziwe i-short circuit ukuthi ubangele umonakalo oyinhlekelele ezintanjeni, ezintweni zikagesi, njll.

3. I-Undervoltage Protection (etholakala kwamanye ama-circuit breaker): Uma i-voltage yegridi yehla ngaphansi kwe-voltage evamile yokusebenza ngezinga elithile, i-circuit breaker inganqamula isekethe ngokuzenzakalelayo ukuze kuvikelwe okokusebenza kukagesi ekulinyazweni ngenxa yokungabi namandla kwamandla. Ngemuva kokuthi i-voltage yegridi ibuyele kokujwayelekile, amanye ama-circuit breaker adinga ukusetha kabusha ngesandla ngaphambi kokuthi anikezwe amandla kabusha, kuyilapho amanye angavala kabusha ngokuzenzakalelayo.

II. Imisebenzi ye-circuit breaker

Ukunikezwa kwamandla okuhlukanisa: Umsebenzi oyinhloko weswishi yokuhlukanisa ukwahlukanisa ngokuthembekile izinto zikagesi ezidinga ukunakekelwa kugesi ophilayo, ukuqinisekisa ukuphepha kwabasebenzi abanakekelayo. Isibonelo, lapho ulungisa izinto zikagesi zomugqa othile esiteshini esingaphansi, ngokusebenzisa inkinobho yokuhlukanisa, indawo yokuphumula ecacile ingakhiwa phakathi kwemishini kanye nokunikezwa kwamandla, ukuvimbela ukunikezwa kwamandla okungazelelwe ekubangeleni ukulimala kwabasebenzi bokunakekela.

2. Ukusebenza kokushintsha: Kubha yebhasi ephindwe kabili noma enye isistimu yezintambo, ukushintshwa okuhlukanisayo kusetshenziselwa ukushintsha imodi yokuxhuma yesekethe, okuvumela okokusebenza noma imigqa ukuthi ishintshwe isuka kwelinye isethi yamabhasi ukuya kwelinye, ngaleyo ndlela iqinisekise ukulungiswa okuguquguqukayo kwemodi yokusebenza yesistimu yamandla. Kodwa-ke, ngesikhathi sokusebenza kokushintsha, ukushintshwa kokuhlukanisa kuvame ukusetshenziswa ngokuhambisana namadivayisi afana nama-circuit breakers.

3. Izifunda ezincane ezisebenzayo zamanje: Iswishi ehlukanisayo ingavula futhi ivale ama-voltage angenaphutha kanye nezibambisi zombani, amabhasi, i-capacitive current yemishini exhunywe ngqo kubha yebhasi, kanye nokushintsha kommese ophansi endaweni engathathi hlangothi ye-transformer, njll., okuyiziyingi ezincane zamanje.

Isinqamuli sesekethe esine-voltage ephansi kagesi

III. Izinqamuli zesekethe zihlukaniswa ngendlela yokukhubeka

I-Thermal circuit breaker: Ikakhulu isebenzisa isimiso sokuthi i-bimetallic strip iyagoba lapho ishiswa. Uma i-current igcwele kakhulu, i-bimetallic strip iyagoba ngenxa yokushisa okukhiqizwa i-current, okubangela indlela yokukhubeka ukuze inqamule isekethe. Isikhathi sesenzo salesi sinqamuleli sesifunda sihlobene nosayizi we-overload yamanje; uma kukhulu ukugcwala kwamandla, isikhathi sesenzo siba mfishane.

2. I-Electromagnetic Circuit Breaker: Ngokusekelwe kumgomo wokungeniswa kwe-electromagnetic. Lapho isifunda esifushane senzeka kusekethe, igagasi elikhulu kungazelelwe likhiqiza amandla kazibuthe kagesi anamandla, okwenza indlela yokukhubeka isebenze futhi inqamule isekethe ngokushesha. Izwela kakhulu kuma-short-circuit currents.

3. I-Electronic Circuit Breaker: Ithola ubukhulu bamanje nezinguquko ngokusebenzisa izingxenye ze-electronic. Ingasebenzisa ngokunembe kakhudlwana imisebenzi yokuvikela efana nokugcwala kakhulu kanye nokujikeleza okufushane, futhi ezinye izinqamuli zesekhethi ze-elekthronikhi nazo zinemisebenzi yesilawuli kude nokuxhumana, okulenza libe uhlobo oluthuthuke kakhulu lwe-circuit breaker.

IV. Ukuhlelwa kokunqamula amaswishi ngendawo yokufaka

Iswishi yokunqamula ngaphakathi endlini: Ivamise ukufakwa egunjini lokusabalalisa noma kwezinye izindawo ngaphakathi kwezakhiwo, isetshenziselwa ukuhlukanisa ukusebenza kwezinto zikagesi zasendlini. Isakhiwo sayo sihlangene futhi umthamo wayo mncane ngenxa yokuthi izimo zemvelo yasendlini azinzile.

2. Amaswishi okunqamula ngaphandle: Afakwe eziteshini ezincane zangaphandle, olayini bakagesi, nakwezinye izindawo, adinga ukuthi akwazi ukumelana nezimo zezulu ezihlukahlukene eziyinkimbinkimbi. Isakhiwo sazo siqinile uma kuqhathaniswa futhi sinezinto ezinhle kakhulu zokungangeni kwamanzi, zingangenwa umoya futhi zimelana nokugqwala.

V. Ukuhlelwa kwamaswishi okunqamula ngokusekelwe endleleni yokusebenza

Iswishi yokunqamula mathupha: Idinga ukusebenza ngesandla ngesibambo ukuze uvule nokuvala. Ukusebenza kulula futhi kuqondile, ngezindleko eziphansi. Ngokuvamile isetshenziswa ezimeni ezinamazinga aphansi kagesi kanye nokusebenza kancane kancane.

2. Iswishi Yokuhlukanisa Kagesi: Izenzo zokuvula nokuvala zitholwa ngomshini wokusebenza kagesi. Lolu hlobo lweswishi yokuhlukanisa luvumela isilawuli kude, lula ukulawula okuphakathi nendawo kanye nokusebenza okuzenzakalelayo eziteshini ezinkulu nezinye izinsiza ezinjalo. Kodwa-ke, inezindleko eziphakeme kakhulu kanye nesakhiwo esiyinkimbinkimbi.
