Lub Hwj Chim Loj Tshaj Tawm Voltage Requirement rau HV Switchgear (12kV System)

Qhov chaw kuaj	Nrog Voltage	Kev kuaj mob	Cov ntsiab lus tseem ceeb	Failure Analysis
Hauv av	42kV/1 min	Phase conductor → grounded enclosure	Txheeb xyuas lub zog rwb thaiv tsev thaum lub sijhawm ib zaug -fault hauv av	Tej zaum yuav ua rau kev puas tsuaj los yog kev tiv thaiv tsis ua haujlwm
Phase -rau-Phase	42kV/1 min	A-B/B-C/C-A theem	Ua kom muaj kev ntseeg siab thaum lub sij hawm theem - mus rau -theem faults lossis load imbalance	Nws tuaj yeem ua rau lub sijhawm luv luv Circuit Court thiab lub cev tawg
Isolation Gap	48kV/1 min	Qhib kev sib cuag (sib cais)	Ntsuas lub peev xwm los tiv thaiv qhov system overvoltages (xws li, hloov surges) thaum qhib	Risks hu rau reignition los yog rwb thaiv tsev flashover

Failure Mode Analysis

Qhov chaw kuaj	Tej Yam Ua	Kev ntsuas txo qis
Hauv av	Contaminated insulators / ib nrab tso tawm	Kev tu tsis tu ncua, SF₆ gas purity checks
Phase -rau-Phase	Hnub nyoog insulating teeb meem / mechanical deformation	Siv cov nplaim hluav taws-cov epoxy barriers
Isolation Gap	Tiv tauj yaig ua rau thaj chaw distortion	Saib xyuas arcing zog, hloov co

 

 

① Ambient kub: -25℃rau +40 degree

② Qhov siab: Tsawg dua lossis sib npaug li 2000m

③ Tus txheeb ze av noo: nruab nrab txhua hnub tsis ntau tshaj 95%; Qhov nruab nrab txhua hli tsis tshaj 90%;

④ Ib puag ncig ib puag ncig: Cov huab cua nyob ib puag ncig tsis muaj kuab lom ntau los ntawm cov pa roj carbon monoxide lossis cov roj hluav taws xob, dej vapor, thiab lwm yam.

⑤ Tsis tshua muaj kev vibration hnyav.

 

 

HXGN 12 AC hlau kaw lub nplhaib network switchgear yog dav siv nyob rau hauv daim phiaj fais fab, fais fab, photovoltaic, kev sib txuas lus, tshuaj, machinery, smelting, roj teb, factories, them pawg, railway chaw nres tsheb, tsev kho mob, tsev kawm ntawv, vaj tse, chaw ua lag luam, thiab lwm yam., yog lub chaw tsim khoom ntawm cov lag luam loj hauv tsev zoo {{2} thiab durability.}

 

● Tshawb xyuas cov yam ntxwv ntawm cov neeg kho tshuab thiab cov rwb thaiv tsev tiv thaiv ntawm qhov hloov txhua xyoo.
● Tsis tu ncua ntxuav lub txee thiab ceev cov khoom sib txuas.
● Lub SF6 hloov yuav tsum tau kuaj xyuas nws cov pa roj (yog tias tsim nyog)
