Nruab nrab-voltage switchgear feem ntau muaj qhov ntsuas hluav taws xob ntawm 3.6kV, 7.2kV, 12kV, 24kV, thiab 40.5kV. Cov kev ntsuas hluav taws xob no sib haum mus rau qhov sib txawv ntawm daim ntawv thov scenarios thiab cov kev xav tau ntawm lub cev, raws li hauv qab no:
- 3.6kV thiab 7.2kV:Lawv yog cov tsis tshua muaj, feem ntau yog concentrated nyob rau hauv tej qhov chaw xws li kev lag luam thiab marine daim ntaub ntawv.
- 12kV :ua.Ib qho ntawm ntau qhov nruab nrab -voltage ratings, nws yog feem ntau pom nyob rau hauv nruab nrab -voltage fais fab tis systems nyob rau hauv tis networks, industrial thiab mining lag luam, thiab cov tsev lag luam. Piv txwv li, cov qauv hloov pauv xws li KYN28-12, XGN15-12, thiab HXGN-12 yog txhua yam muaj nyob hauv 12kV qhov ntsuas hluav taws xob thiab siv rau kev faib hluav taws xob, tswj, thiab kev tiv thaiv hauv 10kV systems.
- 24kv :ua.Nws daim ntawv thov scenarios yog qhov tshwj xeeb, thiab txawm tias tsis yog dav li 12kV thiab 40.5kV, nws kuj yog siv rau hauv qee qhov nruab nrab -voltage fais fab tshuab nrog siab rwb thaiv tsev xav tau lossis tshwj xeeb xav tau.
- 40.5 kV:Qhov ntsuas hluav taws xob no kuj muaj cov ntawv thov siab thiab feem ntau siv hauv cov chaw loj loj, cov chaw tsim hluav taws xob, thiab cov chaw ua haujlwm hnyav. Switchgear qauv xws li KYN61-40.5 thiab GZS1-40.5 yog tsim rau 35kV systems thiab muaj peev xwm ua tau raws li lub rwb thaiv tsev thiab tiv taus qhov voltage ntawm cov khoom siv hluav taws xob ntawm qib siab dua.
Hauv kev siv cov tswv yim, switchgear tuaj yeem npog cov qib qis qis thaum ua tau raws li qhov kev xav tau ntawm rwb thaiv tsev hluav taws xob ntawm daim ntawv thov ib puag ncig. Piv txwv li, 12kV switchgear tuaj yeem siv rau hauv 3kV thiab 6kV systems ntawm qhov siab tshaj 1000 meters.
