Khoom
Nqus interrupter rau inflatable txee (132A)
Cov lus piav qhia luv luv ntawm cov khoom:
Xyoo 1926, ib pab pawg coj los ntawm Royal Sorensen ntawm California Institute of Technology tau tshawb xyuas lub tshuab nqus tsev hloov thiab sim ntau yam khoom siv;Cov ntsiab lus tseem ceeb ntawm kev cuam tshuam arc hauv lub tshuab nqus tsev tau tshawb xyuas.Sorenson nthuav tawm cov txiaj ntsig ntawm AIEE lub rooj sib tham xyoo ntawd, thiab kwv yees cov keyboards 'kev lag luam siv.Xyoo 1927, General Electric tau yuav cov cai patent thiab pib ua lag luam.Kev Nyuaj Siab Loj thiab kev txhim kho cov roj puv hloov pauv ua rau lub tuam txhab txo qis kev txhim kho kev ua haujlwm, thiab kev lag luam tseem ceeb me me tau ua tiav ntawm lub tshuab nqus tsev hloov pauv mus txog xyoo 1950.
Xyoo 1956, H. Cross revolutionized lub high-frequency-circuit nqus tsev vacuum hloov thiab tsim ib lub tshuab nqus tsev hloov nrog ib tug ntsuam xyuas ntawm 15 kV ntawm 200 A. Tsib xyoos tom qab, Thomas H. Lee ntawm General Electric tsim thawj lub tshuab nqus tsev Circuit Court breakers nrog ib tug ntsuas. voltage ntawm 15 kV ntawm luv-circuit breaking tam sim no ntawm 12.5 kA.Xyoo 1966, cov khoom siv tau tsim nrog qhov ntsuas hluav taws xob ntawm 15 kV thiab luv-circuit breaking tam sim no ntawm 25 thiab 31.5 kA.Tom qab xyoo 1970s, lub tshuab nqus tsev hloov pauv pib hloov cov roj tsawg-tsawg hloov hauv nruab nrab-voltage switchgear.thaum xyoo 1980s, SF6 keyboards thiab breakers kuj maj mam hloov los ntawm lub tshuab nqus tsev vacuum nyob rau hauv nruab nrab-voltage daim ntawv thov.
Raws li xyoo 2018, lub tshuab nqus tsev hluav taws xob tau mus txog 145 kV thiab tam sim no tawg tau mus txog 200 kA.
30 xyoo Siemens nqus tsev vacuum interrupter
Cov neeg sib cuag nqa lub voj voog tam sim no thaum kaw, tsim cov terminals ntawm lub arc thaum qhib.Lawv yog ua los ntawm ntau yam ntaub ntawv, nyob ntawm seb lub tshuab nqus tsev interrupter siv thiab tsim rau lub neej ntev kev sib cuag, ceev ceev rov qab voltage tiv thaiv kev ntsuam xyuas, thiab kev tswj ntawm overvoltage vim yog tam sim no chopping.
Ib qho kev ua haujlwm sab nraud ua rau kev txav mus los, uas qhib thiab kaw qhov txuas txuas.Lub tshuab nqus tsev cuam tshuam suav nrog lub tes tsho qhia los tswj kev txav mus los thiab tiv thaiv lub tshuab sealing los ntawm kev sib tw, uas yuav ua rau nws lub neej luv luv.
