ZN12-12 sab hauv tsev nqus Circuit Court breaker arc extinguishing txoj cai.
Hauv lub tshuab nqus tsev vim qhov nruab nrab ntawm kev mus ncig dawb ntawm cov pa roj molecules yog qhov loj heev, cov pa roj tsis yooj yim los tsim dawb, lub zog rwb thaiv tsev ntawm lub tshuab nqus tsev yog ntau dua li cov rwb thaiv tsev lub zog ntawm cov cua. Thaum tus hloov qhib lub rooj vag, lub arc yog generated ntawm cov neeg. Qhov chaw tiv tauj volatilises hlau vapor ntawm qhov kub thiab txias. Vim qhov tshwj xeeb zoo ntawm kev sib cuag tsim, ib qho chaw sib nqus yog tsim thaum lub sijhawm tam sim no dhau mus, thiab lub arc txav ceev ceev hauv qab lub zog ntawm qhov chaw sib nqus no. Nyob rau hauv lub tog raj kheej hlau (ie shield) ntawm condensation ntawm ib feem ntawm cov hlau vapor. Lub arc yog extinguished thaum nws ib txwm dhau los ntawm xoom, thiab lub zog dielectric ntawm kev sib cuag tau sai sai.
Lub Circuit Court breaker no txais cov khoom siv tshwj xeeb, uas ua rau chav cuam tshuam muaj peev xwm qhib siab dua, txo qis kev cuam tshuam thiab lub neej hluav taws xob ntev.
ZN12-12 sab hauv tsev nqus Circuit Court breaker kev khiav hauj lwm mechanism.
6.1 Cov txheej txheem kev khiav hauj lwm feem ntau muaj lub zog cia mechanism, xauv lub tshuab, tawg lub caij nplooj ntoos hlav, hloov spindle, tsis thiab tswj cov cuab yeej, muaj pes tsawg leeg.
6.2 Lub cev tseem ceeb ntawm lub zog cia lub cev yog lub plhaub rau lub cam khwb cia txhuas ceev reducer lub thawv, lub thawv ceev reducer yog ob pawg ntawm cov iav iav, lub zog cia ncej hla lub thawv ceev reducer, thiab cab iav iav tsis muaj kev sib cuag. Lub zog khaws cia ntawm lub tes tsho, lub tes tsho nrog ib qho tseem ceeb txuas nrog lub iav loj loj, lub tes tsho muaj tus pin ncej, saum toj ntawm kev teeb tsa ntawm lub pawl, hauv qhov chaw khaws cia los ntawm sab xis kawg ntawm lub ncej muaj lub cam, cam ntawm qhov thais, lub pawl los ntawm qhov ntsuas no kom tsav lub cam tig. Nyob rau sab laug kawg ntawm qhov chaw cia khoom muaj lub crank, thiab ib qho kawg ntawm lub caij nplooj ntoos hlav kaw yog dai rau ntawm lub crank no.
6.3 Muaj ib daim duab peb sab ntawm tus pin ntawm lub gearbox, thiab lub zog yog haum nrog rab koob kom lub zog ntawm lub cam-loaded kaw lub caij nplooj ntoos hlav tuaj yeem xa mus rau cov kabmob no. Lwm qhov ntawm lub tog raj kheej kheej kheej, nrog tus pin ncej txuas nrog kev sib txuas, lwm qhov kawg ntawm qhov kev sib txuas yog mounted rau ntawm spindle caj npab, tsim ib tug plaub-txuas mechanism, lub kaw quab yuam yog kis mus rau qhov hloov spindle los ntawm no mechanism. Tus pin ncej ntawm qhov txo qis gearbox kuj tseem haum nrog rab koob bearing, uas yog siv los ua tus nres nres.
6.4 Nyob rau hauv lub hloov spindle caj npab yog nruab nrog ib tug split caij nplooj ntoos hlav, lub spindle muaj peb khub ntawm caj npab, ob tug uas yog ua nyob rau hauv lub kaw cov roj hmab tsis thiab cais nres roj tsis, lwm ob txhais caj npab ntawm ib rab koob bearings raws li ib tug locking nres nrog.
6.5 Muaj qhov sib npaug ntawm qhov kaw thiab qhib qhov ua rau cov khoom no.
