Cov Qeb Ua Haujlwm ntawm Switchgear

1. Txee nkag (Txee nkag)

Lub Luag Haujlwm: Txais lub zog los ntawm lub grid thiab faib nws mus rau cov khoom siv tom qab los ntawm cov circuit breakers, CTs (Current Transformers), thiab PTs (Cov Hloov Fais Fab Voltage).

 

Qhov Tseem Ceeb: Ua haujlwm ua lub ntsiab interface rau kev sib txuas ntawm grid.

 

2. Txee Tawm (Txee Faib Khoom)

Lub Luag Haujlwm: Faib fais fab los ntawm lub busbar mus rau cov kab tawm, kom ntseeg tau tias muaj kev xa hluav taws xob ruaj khov rau cov khoom siv kawg.

 

3. Txee Txuas Busbar

Lub Luag Haujlwm: Txuas ob ntu busbar, txhawb nqa ib lub tsheb npav lossis ob lub tsheb npav rau kev ywj pheej ua haujlwm.

 

​4. PT Txee (Muaj peev xwm hloov pauv tau Lub txee)

Lub Luag Haujlwm: Saib xyuas qhov hluav taws xob ntawm lub busbar thiab pab txhawb cov txheej txheem tiv thaiv. Nruab nrog cov PTs, cov hloov pauv cais, fuses, thiab cov khoom tiv thaiv hluav taws xob.

 

​5. Txee cais tawm​

Lub Luag Haujlwm: Muab ib qho chaw txiav tawm uas pom tseeb rau kev saib xyuas, cais cov busbars lossis cov khoom siv ntawm cov chaw muab hluav taws xob. Yuav tsum tau sib txuas nrog cov circuit breakers kom tiv thaiv kev ua haujlwm tsis raug.

 

6. Txee Rau Kev Them Nyiaj Capacitor

Lub Luag Haujlwm: Txhim kho qhov muaj zog thiab txo cov khib nyiab hluav taws xob los ntawm kev them rov qab fais fab.

 

7. Txee ntsuas

Lub Luag Haujlwm: Ntsuas kev siv zog (kWh) siv cov meters, CTs, PTs, thiab cov khoom siv pabcuam xws li cov khoom saib xyuas kev thauj khoom.

 

8. Txee GIS (Gas-Insulated Switchgear)

Lub Luag Haujlwm: Cov ntawv thov high-voltage/high-capacity siv SF6 roj rau kev rwb thaiv tsev, ua kom muaj kev nyab xeeb thiab kev ntseeg siab.

 

Cov Cheebtsam Tseem Ceeb thiab Lawv Lub Luag Haujlwm

Lub tshuab hluav taws xob Circuit Breaker

​Kev Ua Haujlwm: Txuas/txiav cov circuits raws li qhov xwm txheej ib txwm muaj thiab cuam tshuam cov hluav taws xob txhaum (piv txwv li, luv circuits).
