Txheej txheem cej luam Vacuum Circuit Court breaker

Taw qhia txog lub tshuab nqus tsev Circuit Court breaker

"Nqus Circuit Court Breaker" tau txais nws lub npe vim nws qhov nruab nrab arc extinguishing nruab nrab thiab rwb thaiv tsev nruab nrab ntawm kev sib cuag tom qab arc extinguishing yog ob lub tshuab nqus tsev siab;nws muaj qhov zoo ntawm qhov me me, lub teeb yuag, haum rau kev ua haujlwm nquag, thiab tsis muaj kev saib xyuas rau arc extinguishing.Daim ntawv thov hauv daim phiaj hluav taws xob yog qhov dav.High voltage nqus Circuit Court breaker yog ib qho khoom siv hluav taws xob sab hauv tsev hauv 3 ~ 10kV, 50Hz peb-theem AC system.Nws tuaj yeem siv rau kev tiv thaiv thiab tswj cov khoom siv hluav taws xob hauv kev lag luam thiab kev lag luam mining, fais fab nroj tsuag, thiab substations.Rau kev saib xyuas thiab siv tsis tu ncua, lub Circuit Court breaker tuaj yeem teeb tsa hauv lub txee nruab nrab, ob chav txheej txee thiab lub txee ruaj khov rau kev tswj thiab tiv thaiv cov khoom siv hluav taws xob siab.

Keeb kwm ntawm Nqus Circuit Court breaker

Xyoo 1893, Rittenhouse hauv Tebchaws Meskas tau thov lub tshuab nqus tsev cuam tshuam nrog cov qauv yooj yim thiab tau txais daim ntawv tsim qauv.Xyoo 1920, Swedish Foga Company tau ua thawj lub tshuab nqus tsev hloov.Cov txiaj ntsig kev tshawb fawb tau luam tawm xyoo 1926 thiab lwm tus kuj tseem qhia tau tias muaj peev xwm ua txhaum tam sim no hauv lub tshuab nqus tsev.Txawm li cas los xij, vim muaj peev xwm tawg me me thiab kev txwv ntawm qib kev txhim kho ntawm lub tshuab nqus tsev thiab cov khoom siv nqus tsev, nws tsis tau muab tso rau hauv kev siv.Nrog rau kev txhim kho ntawm lub tshuab nqus tsev, nyob rau xyoo 1950, Tebchaws Meskas tsuas yog ua thawj pawg ntawm lub tshuab nqus tsev twj tso kua mis tsim nyog rau kev txiav tawm lub tsev txhab nyiaj capacitor thiab lwm yam tshwj xeeb uas yuav tsum tau ua.Qhov tawg tam sim no tseem nyob rau theem ntawm 4 txhiab amps.Vim muaj kev nce qib hauv cov khoom siv nqus tsev smelting thev naus laus zis thiab kev ua tiav hauv kev tshawb fawb ntawm lub tshuab nqus tsev sib txuas, xyoo 1961, kev tsim cov tshuab nqus tsev vacuum nrog lub zog ntawm 15 kV thiab tawg tam sim no ntawm 12.5 kA pib.Nyob rau hauv 1966, 15 kV, 26 kA, thiab 31.5 kA lub tshuab nqus tsev Circuit Court breakers tau sim tsim, kom lub tshuab nqus tsev Circuit Court breaker nkag mus rau high-voltage, loj-muaj peev xwm fais fab system.Nyob rau hauv nruab nrab-1980s, lub peev xwm ntawm lub tshuab nqus tsev vacuum breakers mus txog 100 kA.Tuam Tshoj pib tsim lub tshuab nqus tsev hloov nyob rau hauv 1958. Nyob rau hauv 1960, Xi'an Jiaotong University thiab Xi'an Hloov Rectifier Hoobkas sib koom ua ke tsim thawj batch ntawm 6.7 kV lub tshuab nqus tsev hloov pauv nrog lub peev xwm tawg ntawm 600 A. Tom qab, lawv tau ua rau 10 kV. thiab muaj peev xwm tawg ntawm 1.5.Qian'an peb-theem lub tshuab nqus tsev hloov.Xyoo 1969, Huaguang Electron Tube Factory thiab Xi'an High Voltage Apparatus Research Institute tau tsim lub tshuab nqus tsev 10 kV, 2 kA ib-theem ceev lub tshuab nqus tsev hloov.Txij li thaum xyoo 1970s, Tuam Tshoj tau muaj peev xwm los tsim thiab tsim cov tshuab nqus tsev vacuum ntawm ntau yam tshwj xeeb.

Specification ntawm Nqus Circuit Court breaker

Nqus Circuit Court breakers feem ntau muab faib ua ntau theem voltage.Hom hluav taws xob tsawg feem ntau yog siv rau kev siv hluav taws xob tawg.Zoo li cov mines thee thiab lwm yam.

Qhov ntsuas tam sim no ncav cuag 5000A, qhov tawg tam sim no nce mus txog qib zoo dua ntawm 50kA, thiab tau tsim mus rau qhov hluav taws xob ntawm 35kV.

Ua ntej xyoo 1980s, lub tshuab nqus tsev vacuum breakers tau nyob rau theem pib ntawm kev txhim kho, thiab lawv tau tshawb nrhiav cov thev naus laus zis tas li.Nws tsis tuaj yeem tsim cov qauv kev qhia.Nws tsis yog txog xyoo 1985 uas cov qauv khoom tsim tau tsim.
