Cov neeg siv Lub tshuab nqus tsev Circuit Court breakertswj cov high voltage tam sim no. Lawv yog qhov zoo tshaj plaws rau kev ua kom pom qhov poob ntawm qhov tsis sib xws tam sim no thiab ob lub ntiaj teb ua txhaum. Nqus Circuit Court breakers yog zoo haum rau siv nyob rau hauv lub hwj chim chaw nres tsheb thiab generators. Tib neeg kuj siv lub tshuab nqus tsev vacuum hauv kev siv tsheb ciav hlau vim tias lawv muaj peev xwm hloov traction tam sim no thiab cov khoom siv hluav taws xob.
Tsis tas li ntawd, VCBs kuj tau siv rau hauv cov hlau-clad switchgear. Qhov sib txawv ntawm Nqus Circuit Court Breakers (VCBs) thiab Cua Circuit Court Breakers (ACBs) Ob Lub Nqus Hluav Taws Xob Hluav Taws Xob (VCBs) thiab Cua Circuit Breakers (ACBs) muaj cov yam ntxwv tseem ceeb. Txawm li cas los xij, lawv muaj ntau qhov sib txawv, raws li hauv qab no:
Kev siv hluav taws xob
Cua Circuit Court breakers tsuas yog siv rau hauv cov ntawv thov uas qhov hluav taws xob tsawg dua 690 volts. Cov no feem ntau hu ua LT (tsawg voltage) daim ntawv thov. Ntawm qhov tod tes, lub tshuab nqus tsev vacuum breakers yog qhov tsim nyog rau qhov nruab nrab qhov ntsuas hluav taws xob nrog qhov hluav taws xob qis dua 33kV.
Txoj Cai ntawm Kev Ua Haujlwm
Cov kev txav mus los thiab zoo li qub tau khaws cia hauv huab cua hauv ib lub pob kaw hauv lub tshuab hluav taws xob hluav taws xob. Yog li ntawd, lub arc yog quenched los ntawm huab cua txhua zaus lub breaker qhib. Cov hluav taws xob hluav taws xob hluav taws xob tau yooj yim ionized vim lawv muaj cua tsawg, uas ua raws li dielectric. Txawm li cas los xij, lub tshuab nqus tsev ua raws li qhov nruab nrab ntawm kev tua hluav taws hauv lub tshuab nqus tsev vacuum. Lub peev xwm ntawm lub tshuab nqus tsev Circuit Court breaker kom tawg lub luv luv Circuit Court yog impressive vim hais tias dawb electrons tsis muaj nyob rau hauv lub nqus tsev vacuum.
Nruab nrab voltage
Qhov qhib cua siab yog txaus los tua ib qho arc nyob rau hauv ib qho hluav taws xob Circuit Court breaker. Ntawm qhov tod tes, lub tshuab nqus tsev vacuum yuav tsum tswj lub tshuab nqus tsev siab ntawm 10-2 rau 10-6 torr.
Rov qab
Vim tias huab cua sab nraum zoov tsis pub dawb, ACB tsis tas yuav tsum tau rov ua dua. Ntawm qhov tod tes, tsis muaj txoj hauv kev kom tau txais lub tshuab nqus tsev hauv VCB. Yog tias lub tshuab nqus tsev tsis ua haujlwm, koj yuav tsum hloov nws.
Daim ntawv thov
Cua Circuit Court breakers feem ntau siv nyob rau hauv LTMCCs, theem nrab feeder circuits rau lub hwj chim transformers, thiab LTPCCs.Lawv yog zoo rau kev siv sab hauv tsev; koj siv tsis tau rau sab nraud. Ntawm qhov tod tes, lub tshuab nqus tsev Circuit Court breakers yog siv los pib lub cev muaj zog ntau dua.
Arc Chute thiab Arc Development
Hauv huab cua Circuit Court breakers, ib qho arc chute yog siv los tiv thaiv arc tsim. Nws faib cov arc rau hauv me me. Yog tsis muaj arc chute, ACB yuav tsis ua haujlwm. Arcing txhim kho sai hauv ACBs.
