Ukuxhumana nomehluko phakathi kwe-earth leakage circuit-breaker kanye ne-over air siwtch

Ukuvuza komhlabaI-circuit breaker, okubizwa ngokuthi "i-leakage switch, ebizwa nangokuthi ukuvuzaama-circuit breakers, ukwehluleka ukuvuza kusetshenziswa kakhulu ezintweni zokusebenza kanye nakumuntu ongaba yingozi othola isivikelo sokushaqeka kukagesi, umsebenzi wokuvikela ukugcwala ngokweqile kanye nokuvikela isifunda esifushane, kungasetshenziswa ukuvikela imigqa noma ukugcwala kwezimoto kanye nesekhethi emfishane, kungaba ezimeni ezijwayelekile ukuze kusetshenziswe. komugqa hhayi ukuqala kokuguqulwa okuvamile.

Ukushintsha umoya: obeye aziwe njengoi-air circuit breaker, i-circuit breaker.Iswishi enqamuka ngokuzenzakalelayo uma i-current in circuit idlula imanje elilinganiselwe.

I-Over and under voltage protector: eyaziwa nangokuthi i-double over and under voltage protector, okusho ukuthi lapho ulayini ongaphezu kwamandla kagesi nangaphansi kwe-voltage yeqa inani elishiwo unganqamula ngokuzenzakalelayo, futhi ikwazi ukubona ngokuzenzakalelayo i-voltage kalayini, lapho i-voltage yomugqa iye evamile ikwazi ngokuzenzakalelayo. vala idivayisi.

Ikakhulukazi isetshenziselwa ukusatshalaliswa kwenxanxathela yezitolo (isigaba esisodwa se-AC230V, imigqa yezigaba ezintathu enezintambo ezine AC415V) njengamandla kagesi angaphezulu, ngaphansi kwamandla kagesi, ukunqanyulwa kwesigaba, ukuvikelwa komugqa wokunqamuka kweqanda.

Ukuxhumana nomehluko phakathi kwesivikeli sokuvuza, iswishi somoya nesivikeli se-over-voltage:

A, isivikelo sokuvuza ngokomsebenzi waso wokuvikela kanye nesigaba sokusetshenziswa sichaziwe, ngokuvamile singahlukaniswa ngokudluliselwa kokuvikela ukuvuza, iswishi yokuvikela ukuvuza kanye nesokhethi yesithathu yokuvikela ukuvuza.

• 1. I-relay yokuvikela ukuvuza ibhekisela kudivayisi yokuvikela ukuvuza enomsebenzi wokubona nokwahlulela amandla avuzayo, kodwa engenawo umsebenzi wokusika nokuvula isekethe eyinhloko.
• 2, iswishi yokuvikela ukuvuza ayibhekiseli kuphela ekutheni ingaxhunywa noma inqanyulwe namanye ama-circuit breaker, kodwa futhi inomsebenzi wokutholwa nokwahlulela kwamanje okuvuzayo.Lapho ukuvuza noma ukulimala kokufakelwa kwenzeka kumjikelezo oyinhloko, ukushintshwa kokuvikela ukuvuza kungaxhunywa noma kunqanyulwe ngokuya ngemiphumela yokwahlulela yesekethe enkulu.
• I-3, isokhethi yokuvikela ukuvuza ibhekisela ekutholeni ukuvuza kwamanje nokwahlulela futhi inganqamula umjikelezo wesokhethi yamandla.Amandla ayo alinganiselwe ngokuvamile angaphansi kuka-20A, isenzo sokuvuza singu-6 ~ 30mA, ukuzwela okuphezulu, okuvamise ukusetshenziselwa ukuvikela amathuluzi kagesi aphathwayo kanye nempahla kagesi ephathwayo nezindlu, izikole nezinye izindawo zomphakathi.

Okwesibili, ukushintshwa komoya kuyinto ebaluleke kakhulu kagesi kunethiwekhi yokusabalalisa i-voltage ephansi kanye nesistimu yokudonsa amandla kagesi, ehlanganisa ukulawula kanye nemisebenzi ehlukahlukene yokuvikela.Ngaphezu kokuqedela ukuthintana kanye nesekhethi yekhefu, kungaba yisekethe noma imishini kagesi isekethe iDemo, ukulayisha ngokweqile kanye nokuvikela okungaphansi kwe-voltage, kodwa futhi ingasetshenziswa ukuqalisa injini njalo.

Isivikeli sokuvuza asikwazi ukufaka isishintshi somoya.Nakuba isivikeli sokuvuza singaphezu kwe-air switch umsebenzi wokuvikela, kodwa ngesikhathi sokusebenza ngenxa yokuthi kungenzeka ukuvuza kuvame ukuba khona futhi kuzovame ukukhubeka okwenzekayo, okuholela ekuphumeni komthwalo ngokuvamile kuzovela ukunqamuka kukagesi, okuthinta ukusebenza okuqhubekayo nokujwayelekile izinto zikagesi.

Ngakho-ke, ngokuvamile endaweni yokwakha kuphela ugesi wesikhashana noma iluphu yesokhethi yezimboni neyomphakathi esetshenziswayo.

Okwesithathu, ngoba idivayisi yokuvikela i-overvoltage kanye ne-undervoltage, abantu abaningi bacabanga ukuthi amathuba okuba igridi yamandla evamile i-zero overvoltage ikhulu, ukuze iminyaka engu-N ingenzeki i-overvoltage, ikakhulukazi usethe uhambo lwe-overvoltage can, ingabe kuyadingeka “ukuzilulama”?

Ngokuvamile, idivayisi yokuvikela inganqamula isekethe ngokushesha nangokuphephile ngaphansi komthelela wamandla kagesi aphezulu oqhubekayo, ukuze kugwenywe ukwenzeka kwezingozi ezibangelwa amandla kagesi angavamile ezintweni zikagesi zokugcina.Lapho i-voltage ibuyela enanini elijwayelekile, umvikeli uzoshintsha ngokuzenzakalelayo isekethe phakathi nesikhathi esibekiwe ukuze aqinisekise ukusebenza okuvamile kwemishini kagesi esigcinayo ezimeni ezingagadiwe.

Isivikeli sokuvuza, ukushintsha komoya kanye nedivayisi yokuvikela i-over-voltage kanye ne-under-voltage, ngayinye inezici zayo, futhi izikhathi ezihlukene nazo zidinga ukukhetha amadivaysi ahlukene, ungakhetha ukuwafaka ngokuya ngezidingo zawo.
