SF6 Circuit Breaker Yooj Yim: Txhua Yam Koj Yuav Tsum Paub

Oct 28, 2026

Tso lus

Taw qhia rau SF6 Circuit Breaker

 

 

Txhais:

IbSF6 Circuit Breakeryog ib hom hluav taws xob hluav taws xob hluav taws xob hluav taws xob uas siv sulfur hexafluoride (SF6) roj raws li cov arc quenching thiab insulating nruab nrab.

 

Keeb kwm thiab kev loj hlob ntawm SF6 Technology:

  • Nrhiav tau nyob rau hauv thaum ntxov 20th caug xyoo
  • Tau txais hauv cov tshuab hluav taws xob los ntawm xyoo 1950
  • Hloov roj thiab cua Circuit Court breakers vim muaj kev ua tau zoo dua
  • Kev txhim kho txuas ntxiv rau kev ua tau zoo thiab kev nyab xeeb

 

SF₆ Gas yog dab tsi?

SF₆ (Sulfur Hexafluoride) yog cov roj tsis muaj xim, tsis muaj ntxhiab, tsis muaj hluav taws kub thiab tsis muaj tshuaj lom.

Nws muaj zoo heev dielectric zog thiab arc quenching zog.

Chemically ruaj khov thiab tsis-corrosive.

ruaj khov molecule heev

 

Cov ntsiab lus tseem ceeb:

  • Siv SF6 roj rau arc quenching thiab rwb thaiv tsev.
  • Haum rau nruab nrab, siab thiab ntxiv-siab voltage daim ntaub ntawv.
  • High dielectric zog thiab zoo heev arc extinguishing muaj peev xwm.
  • Ua kom ntseeg tau kev ua haujlwm thiab kev tiv thaiv system.
  • Dav siv nyob rau hauv substations thiab fais fab kis tes hauj lwm.

 

 

Basic Function:

Lub luag haujlwm tseem ceeb ntawm SF6 Circuit Breaker yog qhib lossis kaw lub voj voog nyob rau hauv ib txwm muaj thiab cuam tshuam cov kev txhaum tam sim no nyob rau hauv qhov txawv txav (luv luv luv) cov xwm txheej los ntawm kev tua cov arc hauv SF6 roj.

 

Kev tsim kho ntawm SF6 Circuit Breaker

Cov khoom tseem ceeb muaj xws li kev sib cuag, roj chamber, nozzle thiab insulators

Muab ntim rau hauv lub tank ntim nrog SF6 roj

Xws li kev khiav hauj lwm mechanism thiab tswj qhov system

 

 

Nws Ua Haujlwm Li Cas? (Hauv cov ntsiab lus yooj yim)

Thaum lub breaker kaw, tam sim no ntws ib txwm.

Thaum muaj kev txhaum tshwm sim, cov kev sib cuag sib cais thiab ib qho yog tsim.

Lub SF6 roj, nyob rau hauv siab siab, quenches lub yog sai sai los ntawm de-ionizing lub txias arc, yog li cuam tshuam cov tam sim no.

Qhov zoo:

★ Siab dielectric zog.

★ Zoo heev muaj peev xwm quenching.

★ Compact me me thiab tsis tu ncua.

★ Kev ntseeg tau thiab lub neej ua haujlwm ntev.

★ Haum rau high voltage thiab high tam sim no daim ntaub ntawv.

Daim ntawv thov:

  • Fais fab kis thiab faib tshuab
  • Substations thiab switchyards
  • Kev lag luam thiab kev lag luam installation
  • Cov nroj tsuag rov ua dua tshiab (Cua, Hnub Ci)
  • Railway hluav taws xob thiab kev siv hluav taws xob
110kV SF6 Application

 

 

Kev sib piv nrog lwm cov Circuit Court Breakers:

Piv rau Cua Circuit Breaker: Zoo dua rwb thaiv tsev thiab arc quenching

Piv rau Nqus Circuit Court Breaker: Haum rau kev siv hluav taws xob ntau dua

Txaus siab rau cov tshuab hluav taws xob ntxiv

 

Xaus:

SF6 Circuit Breakers ua lub luag haujlwm tseem ceeb hauv cov tshuab hluav taws xob niaj hnub los ntawm kev ua kom muaj kev nyab xeeb, txhim khu kev qha thiab muaj txiaj ntsig cuam tshuam ntawm kev txhaum tam sim no nrog kev pab los ntawm cov khoom zoo ntawm SF6 roj.
