I-ZW32-12F Isekhethi ye-vacuum yangaphandle

Incazelo emfushane:

I-ZW32-12/T630-20 Type Vacuum Circuit Breaker iyimishini yokusabalalisa yangaphandle ene-voltage elinganiselwe engu-12KV, ikalwe ngo-630A yamanje, i-AC 50HZ yezigaba ezintathu. Isetshenziselwa kakhulu ukuvula nokuvala umthamo wamanje, wamanje ogcwele ngokweqile kanye nowesifunda esifushane uhlelo lwamandla. Ilungele ukusebenza njalo kugridi yamandla ezolimo, igridi kagesi kanye namabhizinisi ezimboni nezimayini.
I-ZW32-12(D) /T630-20 inhlanganisela yokushintsha iyi-switchgear yangaphandle engu-12KV ene-vacuum circuit breaker kanye ne-isolation switch kanye nendlela yayo yokuxhuma. Ngaphezu kwayo yonke imisebenzi ye-circuit breaker, ingabuye ihlangabezane nemfuneko yokuthi kufanele kube nekhefu elicacile lokuzihlukanisa lapho i-breaker circuit ishintshiwe, futhi ummese wokuhlukanisa unomshini othembekile wokuxhuma idivayisi nomzimba we-breaker circuit, okuyinto. ingaqinisekisa ukuphepha komuntu siqu kwabasebenzi besondlo. Ngokomshini wokusebenza, i-vacuum circuit breaker ihlukaniswe yaba izinhlobo ezimbili: indlela yokusebenza yasentwasahlobo kanye nendlela yokusebenza kazibuthe unomphela. Phakathi kwazo, umshini wokusebenza kazibuthe unomphela uhlukaniswe waba izinhlobo ezimbili: i-bi-stable kanye ne-mono-stable.I-ZW32 vacuum circuit breaker ingahlonywa i-CT over-current protection, i-isolation switch, i-PT yangaphandle, isilawuli esihlakaniphile (i-watchdog), ibhokisi lemitha idivayisi, njll. Ngokwezidingo zomsebenzisi, ukuhlangabezana nezidingo zezikhathi ezihlukahlukene.

Imininingwane Yomkhiqizo

Izici Eziyinhloko

Uhlolojikelele

I-ZW32-12F isinqamuleli iyisisetshenziswa sokusabalalisa amandla sangaphandle esinogesi olinganiselwe we-12KV induction AC 50Hz. Isetshenziselwa kakhulu ukuvula nokuvala umthamo wamanje, ukulayisha ngaphezulu kwamandla amanje kanye ne-short-circuit yamanje ohlelweni lwamandla.
Inhloso eyinhloko ukuvula nokuvala umthamo wamanje, ukulayisha ngaphezulu kwamandla amanje kanye ne-short-circuit current ohlelweni lwamandla. Ilungele ukuvikelwa nokulawula ezinhlelweni zokusabalalisa amandla eziteshini ezincane kanye namabhizinisi ezimboni kanye nezimayini, futhi ifaneleka kakhulu amanethiwekhi kagesi asemaphandleni kanye nezindawo zokusebenza njalo.
Umkhiqizo ungahlangabezana nezidingo zesistimu ezenzakalelayo futhi wenze umsebenzi we-Recloser ongokwesiko ngokwethembeka nangempumelelo. Iswishi isebenzisa isiphazamisi se-vacuum njengendawo ephazamisayo.

Inombolo yemodeli nencazelo

Amapharamitha amakhulu wezobuchwepheshe(Ithebula - 1)

Umkhiqizo usebenza kusukela kumthombo wamandla we-low-voltage AC/DC220V (110V) onikezwe umsebenzisi noma ovela ku-voltage yesibili i-AC220V (110V) exhunywe ngokuqondile ku-voltage mutual inductor (yangaphandle) esuka emugqeni ongaphezulu.

Umthombo. Ukuvikelwa okwakhelwe ngaphakathi, i-inductor yamanje elandelanayo enguziro, okuthathu, isilinganiso esingu-600/1.

Amapharamitha wezimpawu zemishini(Ithebula - 2)

Indlela yokusebenza

Lo mkhiqizo ungowokugcina amandla kagesi, ukuvulwa nokuvala kukagesi, futhi unokugcinwa kwamandla okwenziwa ngesandla, ukuvula nokuvala ngesandla, ukuvikela okungaphezu kwamanje, sonke isakhiwo siqukethe intwasahlobo yokuvala, uhlelo lokugcina amandla, ukukhululwa okungaphezu kwamanje, ikhoyili yokuvula nokuvala. , Isistimu yokufunda yokuvula nokuvala, ukushintsha okuyisizayo kanye nenkomba yokugcina amandla nezinye izingxenye.

Isimiso Sesenzo

Inqubo yokugcina amandla.

Donsa indandatho yomshini wokulondoloza amandla, noma unikeze indlela, isignali yokugcina amandla kagesi, injini ishayela ingalo yokulondoloza amandla ukuze igcine amandla esiphethwini sokugcina amandla, futhi igcine la mandla ngokusebenzisa iluphu yokubamba isitoreji samandla.

Inqubo yokuvala.

Lapho uvala i-circuit breaker, ukudonsa indandatho yokuvala yesandla noma ukunikeza isignali yokuvala kagesi emshinini, amandla entwasahlobo avaliwe ayakhululwa, i-shaft ephumayo yomshini iyazungeza, futhi ukuthintana okunyakazayo kwesiphazamisi kuhanjiswa phezulu ngengalo ye-inflection. kanye nepuleti lokuxhumanisa lokushayela ukuze lithinte othintana naye omile futhi linikeze ingcindezi yokuxhumana, kuyilapho igcina amandla entwasahlobo ephukayo futhi igcina isinqamuli sesifunda sisesimweni esivaliwe ngokubopha okuvamile kweluphu yokubamba yokuvala yomshini.

Inqubo yokuphuka.

Lapho i-breaker yesifunda iphukile, indandatho yokuphumula eyenziwa ngesandla iyadonswa noma isignali yokuphuma kukagesi inikezwa umshini, futhi indandatho evalayo yokugcina yendlela iyavulwa. Isimo sokuphuka sigcinwa yi-switch breaking spring.

Inqubo yokuvikela yamanje.

Lapho i-current egeleza kwisekethe enkulu yesiphazamisi idlula isilinganiso sesiphazamisi, okukhiphayo kwamanje okuvela ohlangothini lwesibili lwesiphazamisi kuzobonisa isilawuli, futhi isilawuli sizonikeza i-voltage yokusebenza kukhoyili ephukayo, okubangela ukuthi isiphazamisi sivuleke. ikhefu.

Uxhumano lwepulaki yendiza

Ukusebenza kwekhodi yokudayela

Khetha ibhendi ngokusho kwetafula lokudayela, futhi inani elihambisanayo yinani elinqunyiwe nomkhawulo wesikhathi odingwa umsebenzisi. Uhlu lumi kanje: 5S.

Ithebula lencazelo yephinikhodi yepulaki yendiza

Ngemva kokuba isilawuli se-BKM600-FDR sifakwe esigxotsheni, sicela uxhume ipulaki yendiza ngokwendawo ephawulwe kuphaneli, qinisa ibhawodi eliphansi futhi uqinisekise ukuphansi okuthembekile.

Bheka ithebula le-Plug Plug Pin 1 kanye nethebula lezincazelo ezingu-2 ukuze uthole izincazelo zezintambo.

Umdwebo ohleliwe wephaneli yedivayisi ye-BKM600-FDR

Imiyalo yezibani ze-LED ezinombala okhanyayo kakhulu

Qaphela: Isimo sokusebenza sesilawuli singanqunywa ngokubheka izinkomba zombala ezihlukahlukene ezivuliwe futhi zivaliwe ezansi kwesilawuli, kanye nelogi yomcimbi we-SOE ingafinyelelwa ngephaneli ye-LCD.

Lawula ukunikezwa kwamandla kanye ne-voltage yokulawula yokuvula nokuvala

Ukunikezwa kwamandla isilawuli se-BKM600-FDR sivela ku-transformer-voltage ephezulu, i-voltage elinganiselwe yomthombo wamandla yi-AC220V, 50HZ, ngemuva kokuthi ipulaki yendiza yomthombo wamandla ixhunyiwe, isilawuli singena ngokuzenzakalelayo esimweni sokusebenza, kanye nesilawuli. inefuse eyakhelwe ngaphakathi engu-2A-6A.
Iswishi ekukholomu Injini yokugcina amandla inikwa amandla amandla kagesi e-PT, axhunywe eswishi esekholomu ngemva kokudlula kusilawuli.
Isilawuli se-BKM600-FDR sine-capacitor yangaphakathi yokugcina amandla, futhi amandla okuvula nokuvala avela kule capacitor. Ukuze ugweme umthelela wokuguquguquka kwamandla kalayini ekusebenzeni kokuvula nokuvala, ukuvulwa nokuvala ugesi wesekethe ophumayo wesekethe yi-DC220V DC voltage. Lapho i-voltage yesifunda yehla ngokuzumayo, i-capacitor inganikeza isikhathi esingekho ngaphansi kwe-8S ukugcina umsebenzi wesilawuli se-BKM600-FDR futhi ikhulule kanye.
Qaphela: Isilawuli se-BKM600-FDR samukela indlela yokushaja yokuqinisa amandla kagesi ukuze kuqinisekiswe ukuthi i-capacitor yokugcina amandla iseduze kwe-DC220V, futhi isikhathi sokushaja se-capacitor singaphansi kuka-0.5S.
