Los ntawm 126kV mus rau 252kV: Qhov Voltage Leap hauv Nqus Tsev Sib Tw Technology - Xov Xwm

Why Must the Vacuum Interrupter Be Installed in a Unified Manner in Deep-Fusion Circuit Breakers with Embedded Poles?

Tau ntau xyoo lawm,Lub tshuab nqus tsev Circuit Court breakersdominated nruab nrab voltage daim ntaub ntawv mus txog 52kV. Txuas lub tshuab nqus tsev cuam tshuam rau hauv kev sib kis hluav taws xob, thawj 126kV thiab tom qab ntawd 252kV, sawv cev rau ib qho tseem ceeb tshaj plaws engineering ua tiav hauv cov tshuab hloov tshiab niaj hnub.

Txhaum 126kV Barrier

Thawj qhov kev sib tw yog 126kV. Cov qauv tsim thaum ntxov tau siv ob lub tshuab nqus tsev cuam tshuam hauv cov koob, nrog rau cov rwb thaiv tsev sab nraud los ntawm SF₆ roj thiab cov qhab nia capacitors kom ntseeg tau tias txawm tias qhov hluav taws xob faib thoob plaws qhov kev so. Ib qho ob - tawg 126kV qauv qhia qhov ua tau, tab sis qhov nyuaj thiab tus nqi tsav kev tshawb fawb mus rau ib qho kev daws teeb meem - tawg. Los ntawm xyoo 2000s, ib zaug - tawg 126kV lub tshuab nqus tsev cuam tshuam tau ua tiav qhov ntsuas ntawm 2000A thiab 40kA, dhau dielectric thiab luv luv- kev ntsuas hluav taws xob. Tus yuam sij enabler yog axial magnetic teb electrode, uas ua rau lub tshuab nqus tsev arc diffuse thaum lub sij hawm siab - cuam tshuam tam sim no.

Vim li cas 252kV txawv

Doubling lub voltage tsis yog tsuas yog scaling. Qhov teeb meem tseem ceeb yog qhov tshwm sim hu ua "saturation" nyob rau hauv lub tshuab nqus tsev ntev. Tshaj li qhov sib txawv ntawm kev sib cuag, nce qhov deb yields diminishing rwb thaiv tsev nce. Qhov no ua rau cov qauv tsim qauv tsis txaus rau 252kV. Lub tshuab nqus tsev cuam tshuam kuj ntsib teeb meem kev ua cua sov: txoj hauv kev ntev ntawm kev sib cuag mus rau lub davhlau ya nyob twg txwv tam sim no - nqa peev xwm. Thiab nrog kev sib cuag loj dua thiab kaw nrawm dua, kev sib cuag bouncing ua hnyav, yuav tsum tau tshwj xeeb damping cov tswv yim.

Txoj Kev mus rau Kev Lag Luam 252kV

Xyoo 2025, lub ntiaj teb thawj zaug 252kV ib zaug - tawgLub tshuab nqus tsev Circuit Court breakerua tiav txhua hom kev xeem thiab nkag mus nyob -grid khiav lag luam hauv Suav teb. Qhov kev ua tiav yuav tsum tau nce qib hauv kev ntsuas rwb thaiv tsev hauv qhov cuam tshuam, tsim cov txheej txheem rau cov hnab ntawv ceramic loj, thiab cov txheej txheem tshiab rau lub tshuab nqus tsev sab hauv. Chav tsev 252kV siv cov ntshiab nitrogen ua cov rwb thaiv tsev sab nraud, tshem tawm SF₆ tag nrho. Nrog rau chav kawm hluav taws xob tam sim no tau ua pov thawj, kev saib xyuas tig mus rau 550kV, qhov twg ntau -kev teeb tsa thiab qhov ntsuas hluav taws xob yuav yog qhov tseem ceeb.
