Nta, switchgear nqus tau tej chaw sai heev. Txij, nqus Circuit Court breaker yog ntau thiab nti tawm tau zoo ua pes tsawg tus neeg zov me nyuam faulty thiab coj qhov twg siab npaum li cas. Nyob hauv nruab nrab voltage daim ntawv switchgear, nqus tsev switchgear yog hom twg 3 36 KV. Ntawv uas ib Circuit Court breaker mas nyob li cov dielectric nruab nrab siv rau arc quenching. Lwm cov loj kom zoo dua technology no, yog tshuab switchgear yog ze li ntawm nkawm dawb.

Arc ceev Quenching

Thaum lub caij qhib rau cov neeg nyob tam sim no nqa tus mob, vapor hlau ua ntawm tus neeg, thiab qhov hlau vapor muab ib txog kev mus txog twg chaw fais nruam yuav ntws mus txog rau tam sim no lub voj tom ntej. Cov phenomenon no yog los yog nqus arc. No arc extinguished nyob ze cov voj tam sim no thiab xov vapor conductive no condensed rov rau tus tiv tauj qhov chaw xuab micro vib nas this. Nws tau raug cai tias, tsuas 1% ntawm cov vapor los yog condensed rov rau arc chamberlub sab phab ntsa, thiab 99% ntawm rov condensed rau qhov chaw hu los ntawm qhov uas nws yog vaporized vapor.

Arc uas tsis muaj zog nyob rau hauv lub tshuab nqus tsev

Lub zog dissipated thaum arc hauv lub tshuab nqus tsev yog li ib caum cov roj thiab ib plaub ntawd SF6 roj. Tsis tshua muaj zog dissipation mas vim tsis hi ncua sij hawm (vim me tsawb kis) thiab me me arc ntev (no yog los ntawm kis me me hu). Vim txoj kev no tsis tshua muaj arc zog dissipation, nqus cov switchgear muaj negligible cuag yaig thiab qhov no yuav qhia nws yuav luag nkawm dawb txoj sia luv. Nws tseem yuav tau muab sau tias, kev coj thiab ua tej yam tam sim no, lub zog yuav tsum tau los ntawm kev nqus Circuit Court breaker yog tsawg kawg yog piv rau cua Circuit Court breaker thiab roj Circuit Court breaker.

Lub zog dielectric xau

Kev muab cuag ncua, nqus tsev siv, yim zaug ntxiv dielectric zog dua huab cua thiab plaub zaug ntxiv dielectric zog dua SF6 cov pa ntawm ib lub bar. Lub zog dielectric qho siab ua luaj, lub tsawb kis ntawm nqus breaker Circuit Court yuav raug tswj tseg me me. Nyob rau hauv no cuag kis me me, arc quenching puas yuav tau siv vim lub zog loj dielectric thiab nqus plua plav kom muaj qhov rov ua hauj lwm ceev zog tom qab hi ncua arc tas nrho cov nqi puv dielectric nyob tam sim no lub voj. Qhov no yuav ua rau switchgear nqus tsim rau capacitor switching.

Tej yam yooj yim tsav Mechanism

Nyob SF6, roj thiab cua Circuit Court breaker, zog ntawm cov neeg yog ib resisted los mas compressed nruab nrab ntawm arc quenching chamber. Tab sis, nyob rau hauv lub tshuab switchgear, yog tsis muaj lub nruab nrab, thiab kuj zog cov neeg yuav tawm tsawg vim yog nws muaj mob me me ntxi, tsav zog tas li yog npaum li cas me me thiab, nyob rau hauv no Circuit Court breaker. Uas yog lus caij nplooj ntoos hlav-caij nplooj ntoos hlav khiav hauj lwm mechanism switchgear lub, hydraulic thiab pneumatic mechanism tsis tau txaus no. Tsav mechanism zauv rau lub siab txhua yam lub neej uas nqus switchgear.

Saud sib tham, nws yog tseeb yuav luag tias, lub zog uas nqus cov switchgear dielectric zaug heev heev thiab sib chwv yaig yog yuav luag negligible.
