Kuv yog Lisa, los ntawm cov chaw tsim khoom lag luam (XDTZ) ntawm lub tshuab nqus tsev vacuum.
Cia kuv qhia dab tsi yog lub tshuab nqus tsev vacuum breaker thiab lub tshuab nqus tsev vacuum ua haujlwm li cas.
1.Lub tshuab nqus tsev Circuit Court breaker yog dab tsi?
Nqus Circuit Court breaker los ntawm qhov tseeb hais tias ob qho tib si arc extinguishing nruab nrab thiab insulating nruab nrab ntawm kev sib cuag kis tom qab arc extinguishing yog lub tshuab nqus tsev siab; nws muaj qhov zoo ntawm qhov loj me, lub teeb yuag, kev ua haujlwm nquag, thiab tsis muaj arc extinguishing txij nkawm.
Lub tshuab nqus tsev Circuit Court breaker yog tsim los ntawm peb qhov tseem ceeb: lub tshuab nqus tsev cuam tshuam, kev ua haujlwm mechanism, bracket, thiab lwm yam khoom siv ntxiv.
2.Lub tshuab nqus tsev vacuum ua haujlwm li cas?
Nqus Circuit Court breaker ua hauj lwm hauv paus ntsiab lus yog tsuas yog raws li nws tshwj xeeb arc extinguishing mechanism thiab rwb thaiv tsev yam ntxwv. Thaum cov khoom txav tau thiab zoo li qub tau tawg nyob rau hauv qhov kev ua haujlwm ntawm kev ua haujlwm, ib qho hluav taws xob arc yog tsim los ntawm cov neeg sib cuag, thiab qhov sib cuag ntawm qhov chaw vapor ntawm qhov kub thiab txias. Vim qhov tshwj xeeb zoo ntawm kev sib cuag tsim, ib tug hlau nplaum yog generated thaum lub sij hawm tam sim no dhau los ntawm, thiab lub arc txav ceev ceev raws li tangential kev taw qhia ntawm qhov chaw tiv tauj nyob rau hauv qhov kev txiav txim ntawm no magnetic teb, thiab condenses ib feem ntawm cov hlau vapor rau. lub tog raj kheej hlau (cov ntaub thaiv npog), thiab cov arc raug tua thaum nws ib txwm dhau los ntawm xoom point, thiab lub zog ntawm qhov nruab nrab ntawm cov neeg sib cuag tau rov qab sai.
Lub tshuab nqus tsev vacuum siv lub tshuab nqus tsev vacuum ua qhov nruab nrab ntawm qhov hluav taws xob tua hluav taws xob, thiab lawv cov khoom siv sab hauv muaj xws li kev sib cuag tseem ceeb, kev sib cuag ruaj khov, kev sib cuag zoo li qub, cov npoo sib cuag zoo li qub, cov npoo sib tiv tauj, tawg, lub tshuab nqus tsev sealing rings, coil springs thiab lwm yam khoom. Thaum qhov tam sim no los ntawm kev tawg ua ib qho arc, lub tshuab nqus tsev Circuit Court breaker ua kom muaj kev nyab xeeb ntawm kev ua haujlwm ntawm Circuit Court los ntawm plaub kauj ruam: disconnection, arc extinguishing, sib cais thiab rov qab. Tshwj xeeb tshaj yog, cov kev sib cuag tseem ceeb yog sib cais los ua ib qho kev tawg hauv cov txheej txheem disconnection; lub arc extinguishing theem ntawm lub arc yog compressed thiab extinguished nyob rau hauv qhov kev txiav txim ntawm tus kheej-extinguishing hluav taws xob teb; cov kev sib txuas uas txav tau thiab zoo li qub tau sib cais los tiv thaiv lub arc los ntawm kev dhia tawm hauv txoj kev sib cais; thiab thaum kawg, lub Circuit Court breaker tau rov qab mus rau nws qhov kev ua haujlwm ib txwm nyob rau hauv lub sijhawm rov qab los xyuas kom muaj kev nyab xeeb ntawm Circuit Court.
Lub arc extinguishing mechanism ntawm lub tshuab nqus tsev vacuum breaker yog txawv ntawm cov tsoos Circuit Court breakers, uas siv lub tshuab nqus tsev ib puag ncig kom lub arc extinguished sai. Nyob rau hauv lub tshuab nqus tsev, lub arc extinguishing tsuas yog nyob ntawm qhov tsim ntawm arc nyob rau hauv cov hlau vapor thiab extinguishing txheej txheem. Lub tshuab nqus tsev me me tam sim no thiab siab tam sim no nqus arc kev ua tau zoo yog qhov sib txawv, tab sis txhua tus cia siab rau cov khoom tshwj xeeb ntawm lub tshuab nqus tsev ib puag ncig kom tua cov arc sai sai.
Feem ntau, lub hauv paus ntsiab lus ntawm lub tshuab nqus tsev vacuum breaker yog ib qho ntawm nws cov yam ntxwv tseem ceeb, kev siv lub tshuab nqus tsev vacuum li arc extinguishing nruab nrab, los ntawm qhov tshwj xeeb magnetic teb tsim thiab hluav taws xob teb cov nyhuv, los xyuas kom meej tias lub arc yog extinguished nyob rau hauv ib tug luv luv lub sij hawm. ntawm lub sijhawm, txhawm rau tiv thaiv kev ua haujlwm nyab xeeb ntawm Circuit Court.
