Uhlobo lweswitshi yombane ophezulu

Iswitshi ye-voltage ephezulu ibhekisa kwimisebenzi yokuvula, ukulawula okanye ukukhusela ekuveliseni umbane, ukuhambisa, ukusasaza, ukuguqula umbane kunye nokusetyenziswa kwenkqubo yamandla. Iswitshi ye-voltage ephezulu isetyenziselwa iimveliso zombane ezinenqanaba le-voltage eliyi-3.6kV ~ 550kV, iiswitshi zokwahlukanisa umbane eziphezulu kunye neeswitshi zokumisa umhlaba, iiswitshi zomthwalo we-voltage ephezulu, ii-reclosing ezizenzekelayo eziphezulu kunye nee-sectionalizers, iindlela zokusebenza ze-voltage ephezulu, izixhobo zokusasaza umbane ezikhusela ukuqhuma eziphezulu kunye neekhabhathi zeswitshi ze-voltage ephezulu.

Iindidi zekhabhinethi ezisetyenziswa rhoqo ze-voltage ephezulu:

(1) Iyunithi ephambili yeringi – ikhabhinethi yokutshintsha umthwalo

Isetyenziswa kwigumbi lokusasaza elisezantsi okanye igumbi lokusasaza elisezantsi elinomthamo wetransformer ongaphantsi kwe-1250kVA.

Iimodeli zekhabhathi zokusasazwa eziqhelekileyo: HXGN15-12, Safe-Ring, SM6

I-switch bay e-1; i-busbar bay ezi-2; i-cable bay ezi-3; i-operating mechanism bay ezi-4; i-control guard bay ezi-5

(2) Ikhabhinethi ephakathi – ikhabhinethi yesaphuli sesekethe

Isetyenziswa kumagumbi okusasaza umbane asemgangathweni ophezulu (ngokubanzi, amandla e-transformer enye makhulu kune-1250kVA).

Imodeli eqhelekileyo: KYN28-12

Iimodeli eziqhelekileyo ze-circuit breaker: VD4, VS1

Igumbi lesibini lezixhobo zokusebenza; Igumbi lebhasi ezimbini; Igumbi leenqwelo eziphathwayo ezintathu ze-circuit breaker; Iintambo ezi-4

(3) Ikhabhathi yokusasazwa kwamandla asisigxina
