Isiphazamisi seVacuum yeMV VCB(iqokobhe leceramic, Umbane olinganisiweyo: 7.2kV-12kV)

Iinkcukacha zeMveliso

Iithegi zeMveliso

Inkcazo emfutshane yemveliso:

Isiphazamisi sevacuum, ekwaziwa ngokuba yityhubhu yokutshintsha ivacuum, lelona candelo lingundoqo lokutshintsha kwamandla ombane aphezulu.Umsebenzi ophambili we-vacuum interrupter kukwenza isekethe ephakathi kunye nephezulu yombane inqumle unikezelo lwamandla egumbi lokucima i-arc ye-arc yokucima iqokobhe le-ceramic ngokusebenzisa i-insulation egqwesileyo ye-vacuum ngaphakathi kwityhubhu, enokucima ngokukhawuleza i-arc kunye nokucinezela okwangoku. , ukuze kuphetshwe iingozi neengozi.
Amandla aphezulu okugquma: Xa kuthelekiswa nezinye izinto ezahlukeneyo zokukhusela ezisetyenziswa kwi-vacuum ye-circuit breaker yi-dielectric medium ephezulu.Kungcono kunawo wonke amanye amajelo ngaphandle komoya kunye ne-SF6, eziqeshwe kuxinzelelo oluphezulu.
Ezi zakhiwo zimbini zingentla zenza ukuba i-breakers isebenze ngakumbi, ingabizi kakhulu kwaye ingabizi kwiindleko.Ubomi babo benkonzo nabo bukhulu kakhulu kunanoma yimuphi omnye umqhubi wesiphaluka, kwaye phantse akukho kugcinwa kuyadingeka.

Iimbonakalo

1. Ixesha lokucima i-arc lifutshane, i-voltage ye-arc iphantsi, amandla e-arc amancinci, ukulahleka koqhagamshelwano kuncinci, kwaye amaxesha okuphuka amaninzi.
2. I-inertia yentonga yesikhokelo esihambayo incinci, ifanelekile ekusebenzeni rhoqo.
3. Indlela yokusebenza incinci, umthamo wonke uncinci, kwaye ubunzima bulula.
4. Amandla okulawula amancinci, kwaye ingxolo yesenzo incinci ngexesha lokusebenza kokutshintsha.
5. Indawo yokucima i-arc okanye i-insulating medium ayisebenzisi ioli, ngoko akukho ngozi yomlilo kunye nokuqhuma.

Qwalasela

Lawula ngokungqongqo umthwalo wangoku.
Umthamo ogqithisiweyo we-vacuum circuit breaker umbi.Ekubeni ukufakwa kwe-thermal kwenziwa phakathi koqhagamshelwano kunye negobolondo ye-vacuum circuit breaker, ukushisa kwi-contact kunye nentonga ye-conductive ihanjiswa ngokukodwa kunye nentonga yokuqhuba.Ukuze wenze ukushisa okusebenzayo kwe-vacuum circuit breaker kungadluli ixabiso elivumelekileyo, ukusebenza kwayo kufuneka kukhawulelwe ngokungqongqo ukuba kube ngaphantsi kunomlinganiselo olinganisiweyo.

Ngaphambili: Isiphazamisi seVacuum yeMV VCB(iqokobhe leceramic, Umbane olinganisiweyo: 7.2kV-12kV)

Okulandelayo: Isiphazamisi seVacuum ye-40.5kV TD-40.5/2500-31.5(163)
