Keeb kwm luv luv ntawm txoj kev loj hlob ntawm lub tshuab nqus tsev Circuit Court Breakers

Xyoo 1893, Rittenhouse ntawm Tebchaws Meskas tau thov kom lub tshuab nqus tsev yooj yim tua hluav taws thiab tau txais kev tsim patent. Xyoo 1920, lub tuam txhab Swedish Foga ua thawj lub tshuab nqus tsev hloov. Cov txiaj ntsig kev tshawb fawb tau luam tawm xyoo 1926 kuj tau pom tias muaj peev xwm tawg tam sim no hauv lub tshuab nqus tsev, tab sis vim muaj peev xwm tawg me me thiab cov kev txwv ntawm lub tshuab nqus tsev thiab cov khoom siv nqus tsev vacuum, nws tsis tuaj yeem muab tso rau hauv kev siv. Nrog rau kev txhim kho ntawm lub tshuab nqus tsev, thawj pawg ntawm lub tshuab nqus tsev hloov pauv tsim nyog rau kev txiav tawm lub tsev txhab nyiaj capacitor thiab lwm yam tshwj xeeb uas yuav tsum tau ua nyob rau hauv Tebchaws Meskas hauv xyoo 1950, nrog rau tam sim no tawg tseem nyob rau theem ntawm 4 kiloamperes. Vim muaj kev nce qib hauv cov khoom siv nqus tsev vacuum smelting technology thiab breakthroughs nyob rau hauv kev tshawb fawb ntawm kev sib cuag qauv ntawm lub tshuab nqus tsev switches, lub tshuab nqus tsev Circuit Court breakers nrog ib tug breaking tam sim no ntawm 12.5 kA thiab 15 kV tau tsim nyob rau hauv 1961. Nyob rau hauv 1966, lub tshuab nqus tsev Circuit Court breakers ntawm 15 kV, 26 kA. , thiab 31.5 kA tau sim ua, tso cai rau lawv nkag mus rau qhov hluav taws xob siab thiab lub zog muaj peev xwm loj. Hauv nruab nrab -1980s, lub peev xwm tawg ntawm lub tshuab nqus tsev hluav taws xob tau mus txog 100 kiloamperes. Tuam Tshoj pib tsim lub tshuab nqus tsev hloov hauv xyoo 1958, thiab xyoo 1960, Xi'an Jiaotong University thiab Xi'an Hloov Rectifier Hoobkas koom ua ke tsim thawj pawg ntawm 6.7kV lub tshuab nqus tsev hloov nrog lub peev xwm tawg ntawm 600A; Tom qab ntawd, 10 kV peb-theem lub tshuab nqus tsev hloov nrog lub peev xwm tawg ntawm 1.5 kA tau ua. Xyoo 1969, Huaguang Electronic Tube Factory thiab Xi'an High Voltage Electrical Equipment Research Institute tau tsim lub tshuab nqus tsev 10kV thiab 2KA ib zaug. Tom qab xyoo 1970, Tuam Tshoj muaj peev xwm los tsim thiab tsim ntau yam tshwj xeeb ntawm lub tshuab nqus tsev hloov.
