Dab tsi yog ob qho kev siv hluav taws xob ntau hauv 10KV hluav taws xob faib hluav taws xob?

Hauv 10kV hluav taws xob faib hluav taws xob, ob lub tshuab hluav taws xob feem ntau siv yog lub tshuab nqus tsev hluav taws xob thiab SF₆ Circuit Court breakers. Lawv yog cov tseem ceeb switchgear Cheebtsam ntawm qhov nruab nrab -voltage tis network, lub luag hauj lwm rau kev ntseeg tau qhib thiab kaw circuits nyob rau hauv ib txwm thiab txhaum. Cov hauv qab no yog ib qho kev qhia thiab kev sib piv ntawm ob hom Circuit Court breakers:

Nws siv lub tshuab nqus tsev siab ua lub arc extinguishing thiab rwb thaiv tsev nruab nrab.

Lub hauv paus ntsiab lus ua haujlwm: Thaum cov kev sib cuag sib cais thiab ib qho arc tsim, cov hlau vapor hauv lub tshuab nqus tsev yog ionized. Thaum tam sim no hla xoom, cov hlau vapor ions sai recombine thiab diffuse, rov ua kom lub zog nruab nrab sai, yog li tua lub arc.

Cov yam ntxwv tseem ceeb:

 Qhov zoo:

Muaj zog arc extinguishing muaj peev xwm, ceev qhib thiab kaw ceev, kev pab lub neej ntev.

Qhov qhib me me nyob deb, compact qauv, me me ntim.

Tsis muaj hluav taws kub lossis tawg, muaj kev nyab xeeb rau ib puag ncig (qhov nruab nrab yog lub tshuab nqus tsev)

.Low tu workload, haum rau kev ua haujlwm tsis tu ncua.

 Qhov tsis zoo:

Tej zaum yuav ua rau overvoltage thaum tawg me me inductive tam sim no, feem ntau yuav tsum muaj kev tiv thaiv overvoltage.

Lub tshuab nqus tsev℃tu thiab nrhiav kom tau yog qhov tseem ceeb.

Daim ntawv thov: Dav siv nyob rau hauv 10kV tis kab, industrial thiab mining enterprise substations, siab -nce lub tsev fais fab mov, cua thiab hnub ci zog boosting chaw nres tsheb, thiab lwm yam, thiab tam sim no yog lub ntsiab tseem ceeb nyob rau hauv lub 10kV system.

Nws siv SF₆ roj raws li kev tua hluav taws thiab hluav taws xob nruab nrab.

Txoj hauv kev ua haujlwm: SF₆ roj muaj cov rwb thaiv tsev zoo heev thiab kev tua hluav taws. Nyob rau hauv siab -kub hluav taws xob arcs, nws decomposes, absorbs zog, thiab thaum lub tam sim no hla xoom, cov khoom decomposition sai recombine thiab diffuse, restores nruab nrab lub zog, ua rau lub arc tua.

Cov yam ntxwv tseem ceeb:

 Qhov zoo:

Zoo heev rwb thaiv tsev thiab arc extinguishing kev ua tau zoo, loj tawg muaj peev xwm.

Lub neej hluav taws xob ntev, tsis muaj suab nrov.

Kev ua haujlwm ruaj khov nyob rau sab hauv tsev, sab nraum zoov, thiab qhov chaw hnyav xws li cov chaw ntub dej thiab cov pa phem.

 Qhov tsis zoo:

SF₆ yog lub tsev cog khoom muaj zog nyob rau hauv Kyoto raws tu qauv, nrog cov teeb meem ntawm kev xau thiab kev kho dua tshiab.

Cov kev xav tau siab rau cov txheej txheem ntau lawm thiab sealing, thiab cov nqi siab dua.

Kev txiav txim siab ntawm SF₆ gas liquefaction hauv qis- qhov kub thiab txias.

Daim ntawv thov ib txwm: Hauv cov ntawv thov uas xav tau lub peev xwm tawg thiab ib puag ncig kev hloov pauv, xws li cov chaw nyob hauv av hauv nroog, ntug hiav txwv lossis thaj chaw muaj kuab paug, thiab cov tuam txhab lag luam loj thiab tsuas yog cov kauj ruam tseem ceeb -down substations. Hauv qib siab dua, nws muaj ntau dua, tab sis nws daim ntawv thov feem ntau qis dua lub tshuab nqus tsev vacuum hauv 10kV teb.

Nqus Circuit Court breakers, vim lawv qhov zoo ntawm ib puag ncig tus phooj ywg, compactness, txij nkawm- dawb, thiab nqi-effectiveness, tau dhau los ua tus qauv kev teeb tsa thiab nyiam xaiv rau 10kV qhov system faib, tuav feem coob ntawm kev lag luam.

SF₆circuit breakers, nrog rau lawv cov kev ua tau zoo heev thiab kev hloov pauv ib puag ncig, tseem muaj lawv cov nqi hloov tsis tau hauv qhov tshwj xeeb thiab tseem ceeb ntawm daim ntawv thov, tab sis vim yog ib puag ncig siab, lawv txoj kev loj hlob raug txwv.

Txoj kev loj hlob zoo: Nrog rau qhov kev xav tau ntawm ib puag ncig nruj, lub tshuab nqus tsev vacuum breaker thev naus laus zis tau nce mus tas li, nrog kev txhim kho tsis tu ncua ntawm kev tawg thiab lwm yam kev ua haujlwm. Nws txoj hauj lwm tseem ceeb yuav tau sib sau ua ke ntxiv. Tib lub sijhawm, "SF₆-dawb" cov hluav taws xob hluav taws xob siv hluav taws xob zoo ib puag ncig (xws li cua qhuav, nitrogen, thiab lwm yam) kuj tseem nyob hauv kev tshawb fawb thiab kev tsim kho thiab kev txhawb nqa.

Yog li ntawd, thaum nug txog cov feem ntau siv Circuit Court breakers nyob rau hauv 10kV tis system, lub tshuab nqus tsev Circuit Court breakers yog thawj yuav tsum tau hais, ua raws li los ntawm SF₆ Circuit Court breakers.

VTZ-12 nqus Circuit Court breaker(tus qauv tshwj xeeb ntawm Tongzhong Hluav Taws Xob Co., Ltd.) tsim los ntawm Shaanxi West Power Tongzhong Electrical Co., Ltd. Nws siv lub tshuab ua haujlwm modular thiab tsim nyog rau ntau yam kev lag luam thiab kev lag luam mining, nrog rau cov khoom siv hluav taws xob. Nws tuaj yeem siv los ua ib lub tawb nqa khoom siv nrog KYN28A-12 switchgear, los yog raws li ib qho chaw ruaj khov nrog cov khoom siv sib cuam tshuam, ua rau nws haum rau XGN2 thiab lwm cov khoom ruaj khov.
