Isiphazamisi se-vacuum se-MV VCB(igobolondo leceramic, I-voltage elinganiselwe: 7.2kV-12kV)

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Incazelo emfushane yomkhiqizo:

Isiphazamisi se-vacuum, esaziwa nangokuthi i-vacuum switch tube, siyingxenye eyinhloko yeswishi yamandla kagesi aphezulu aphakathi nendawo.Umsebenzi oyinhloko wesiphazamisi se-vacuum ukwenza isekethe ye-voltage ephakathi nendawo nephezulu inqamule ukunikezwa kwamandla kwegumbi lokucisha i-arc ye-vacuum yegobolondo le-ceramic ngokusebenzisa ukufakwa okuhle kakhulu kwe-vacuum ngaphakathi kweshubhu, engacisha ngokushesha i-arc futhi icindezele amandla amanje. , ukuze kugwenywe izingozi nezingozi.
Amandla okuvikela aphezulu: Uma kuqhathaniswa neminye imithombo yezokuxhumana ehlukahlukene esetshenziswa ku-circuit breaker vacuum iyi-dielectric medium ephakeme kakhulu.Ingcono kunayo yonke eminye imithombo yezindaba ngaphandle komoya kanye ne-SF6, eqashwe ngengcindezi ephezulu.
Lezi zakhiwo ezimbili ezingenhla zenza ama-breaker asebenze kahle, angabi mkhulu futhi ashibhe ngezindleko.Impilo yabo yesevisi nayo inkulu kakhulu kunanoma iyiphi enye i-circuit breaker, futhi cishe akukho ukulungiswa okudingekayo.

Izici

1. Isikhathi sokucisha i-arc sifushane, i-arc voltage iphansi, amandla e-arc mancane, ukulahlekelwa kokuxhumana kuncane, futhi izikhathi zokuphuka ziningi.
2. I-inertia yenduku yokuqondisa ehambayo incane, efanelekile ukusebenza njalo.
3. Indlela yokusebenza incane, ivolumu iyonke incane, futhi isisindo silula.
4. Amandla okulawula mancane, futhi umsindo wesenzo mncane ngesikhathi sokusebenza kokushintsha.
5. Indawo yokucima i-arc noma i-insulating medium ayisebenzisi amafutha, ngakho-ke ayikho ingozi yomlilo nokuqhuma.

Lalela

Lawula ngokuqinile umthwalo wamanje.
Umthamo wokulayisha ngokweqile we-vacuum circuit breaker umpofu.Njengoba ukufakwa kwe-thermal kwakhiwa phakathi kokuxhumana kanye negobolondo le-vacuum circuit breaker, ukushisa othintana naye kanye nenduku ye-conductive kudluliselwa ngokuyinhloko eduze kwenduku ye-conductive.Ukuze wenze izinga lokushisa lokusebenza le-vacuum circuit breaker lingeqi inani elivumelekile, ukusebenza kwayo kufanele kukhawulelwe ngokuqinile ukuze kube ngaphansi kunokwamanje olinganiselwe.

Okwedlule: Isiphazamisi se-vacuum se-MV VCB(igobolondo leceramic, I-voltage elinganiselwe: 7.2kV-12kV)

Olandelayo: Isiphazamisi seVacuum Ku-40.5kV TD-40.5/2500-31.5(163)
