Uhlobo lwesigubhu se-voltage ephezulu

I-switchgear enamandla aphezulu ibhekisela emisebenzini yokuvala, ukulawula noma ukuvikela ekukhiqizeni amandla, ukudlulisa, ukusatshalaliswa, ukuguqulwa kwamandla kanye nokusetshenziswa kohlelo lwamandla. I-switchgear enamandla aphezulu isetshenziselwa imikhiqizo kagesi enezinga le-voltage elingu-3.6kV ~ 550kV, ama-switch okuzihlukanisa aphezulu kanye nama-grounding switch, ama-switch omthwalo aphezulu, ama-reclosing azenzakalelayo aphezulu kanye nama-sectionalizer, izindlela zokusebenza ezinamandla aphezulu, amadivayisi okusabalalisa amandla angaqhumi aphezulu kanye namakhabethe okushintsha amandla aphezulu.

Izinhlobo zekhabhinethi ezisetshenziswa kakhulu ezine-voltage ephezulu:

(1) Iyunithi eyinhloko yeringi – ikhabhinethi yokushintsha umthwalo

Isetshenziswa ekamelweni lokusabalalisa elinesisekelo esiphansi noma ekamelweni lokusabalalisa elinesisekelo esiphezulu elinomthamo we-transformer ongaphansi kuka-1250kVA.

Amamodeli ekhabhinethi okusabalalisa avamile: HXGN15-12, Safe-Ring, SM6

I-switch bay eyi-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 ye-circuit breaker

Isetshenziswa emakamelweni okusabalalisa amandla anesisekelo esiphezulu (ngokuvamile, amandla e-transformer eyodwa makhulu kune-1250kVA).

Imodeli evamile: KYN28-12

Amamodeli avamile okuhlukanisa isifunda: VD4, VS1

Igumbi lesibili lezinsimbi zomculo; Igumbi lebhasi lama-2; Igumbi lenqola yesandla lama-3 le-circuit breaker; Izintambo ezi-4

(3) Ikhabhinethi yokusabalalisa amandla aqinile
