Nqus Breaker Circuit Court

Nyob hauv ib lub tshuab nqus tsev Circuit Court breaker, nqus interrupters los mus coj thiab kev thauj khoom thiab currents txhaum. Thaum cov neeg nyob rau hauv lub tshuab interrupter cais, cov chaw yuav tsum tu ncua initiates vapour hlau arc paug tawm thiab faib los ntawm cov ntshav mus txog rau tam sim no lub voj tom ntej.

Tus arc no ces extinguished thiab cov hlau conductive vapour condenses rau qhov chaw nyob rau hauv ib cov teeb meem ntawm qhov micro vib nas this hlau. Yog li ntawd lub zog hauv lub breaker dielectric leem sai heev.

SF6 Gas Circuit Court Breaker

Nyob rau hauv ib qho SF6 Circuit Court-breaker, cov chaw tseem ntws tom qab sib chwv sib cais los ntawm arc hauv nws cov ntshav muaj ionized SF6 gas. Kev, tau tsuav nws yog kub, rau arc yog nyuam ib qhov txaus roj uas extracts tshav kub los ntawm nws. Tus arc yog extinguished nyob xoom tam sim no, thaum tshav kub kub yog muab rho tawm los ntawm cov chaw poob. Qhov txaus continuing roj thaum kawg de-ionises tus tiv tauj ntxi thiab siv dielectric zog yuav tsum tau tiv thaiv ib rov thos.

Kev khiav hauj lwm yuav tsum zog

Khiav hauj lwm ua zog yuav tsum muaj, vim cov mechanism yuav tsum muab lub zog yuav tsum tau mus hlob cov roj.

Khiav hauj lwm ua zog yuav tsum muaj tsawg tsawg xwb, vim cov mechanism yuav tsum txav masses xwb kuj me me ntawm ntsis ceev, nyob tsis ntev mus. Tus mechanism tsis tas yuav muab lub zog los ua cov roj txaus

Khiav hauj lwm ua zog yuav tsum muaj tsawg tsawg xwb, vim cov mechanism yuav tsum txav masses xwb kuj me me ntawm ntsis ceev, hla mus tsis ntev heev.

Arc zog

Vim yog lub siab conductivity txog rau arc hauv lub SF6 gas, tus arc zog yog tsawg kawg. (arc voltage yog ntawm 150 200V.)

Vim yog cov coob heev voltage hla cov hlau vapour arc, zog yog muaj tsawg kawg nkaus. (Arc voltage yog 50 thiab 100V.)

Hu rau yaig

Vim yog lub zog uas tsis muaj qhov sib chwv yaig no.

Vim lub zog arc coob heev, qhov no ceev ceev cov hauv paus hniav tus arc hla kev tiv tauj thiab cov Disease fact tias feem coob ntawm cov hlau vapour condenses rov rau ntawm kev tiv tauj, nkaws sib chwv yaig yog.

Arc extinguishing tawm

Qhov nruab nrab SF6 gaseous possesses dielectric yav tom ntej thiab arc quenching zog. Tom qab arc extinction, cov roj dissociated molecules recombine yuav luag txhua nrho rau SF6 kho dua tshiab. Qhov no txhais tau tias suab tsis poob/noj tau hauv nruab nrab lub quenching no tshwm sim. Cov roj siab yuav tau ib tsab heev thiab zwm saib xyuas lawv. Muaj nuj nqi no mas tsis tas yuav nyob qhov twg cov cov interrupters yog ntim rau lub neej.

Extinguishing tsis muaj tig ntxiv yog yuav tsum tau txhaj. Nqus plua plav nyob ib siab 10-7 bar los yog tsawg dua yog ib qho yuav luag zoo tagnrho extinguishing nruab nrab. Tus interrupters yog 'lo rau lub neej' kom tswj xyuas cov cav nqus tsev no tsis yog yuav tsum tau txhaj.

Cwj pwm switching in relation to zog ntov tam sim no

Lub siab build-up thiab thiaj li txaus cov roj yog ywj siab hais txog cov nqi ntawm cov chaw. Currents me los loj yog txias nrog tus siv tib yam. Tsuas me qhov tseem ceeb ntawm kev loj, nraum currents, yog muaj, yuav tsum tu ncua. Cov de-ionization ntawm lub tsawb kis proceeds heev zus, vim yog lub electro-tsis xeeb ceem ntawm cov pa roj SF6 thiab cov khoom uas arc.

Lub siab build-up thiab thiaj li txaus cov roj ntawd yog thaum tus nqi ntawm cov chaw yuav tsum tu ncua. Currents loj yog txias ib, currents me me maj mam muab.
