Cov yam ntxwv zoo
1. Lub Circuit Court breaker adopts lub hauv paus ntsiab lus ntawm rotating arc extinguishing, uas siv lub magnetic teb quab yuam exerted los ntawm arc tam sim no ua rau lub arc tig ntawm kev kub ceev raws li ib feem. Txij li thaum qhov loj ntawm lub arc yog lub teeb, thaum lub sij hawm high-speed tig, lub arc yog maj lengthened thiab tsis tu ncua raug rau huab cua ntshiab. SF6 roj yog extinguished thaum txias. Cov qauv Circuit Court breaker no muaj qhov zoo ntawm qhov muaj zog arc extinguishing muaj peev xwm, lub neej ntev hluav taws xob, tsis muaj qhov cuam tshuam tam sim no thaum tawg me me tam sim no, thiab tsis muaj kev khiav hauj lwm overvoltage. Nyob rau tib lub sijhawm, nws yuav tsum muaj lub zog ua haujlwm qis thiab muaj kev ntseeg siab.
2. Lub Circuit Court breaker adopts miniaturized caij nplooj ntoos hlav kev khiav hauj lwm mechanism, uas muaj qhov zoo ntawm txhim khu kev qha kev txiav txim, lub neej txhua yam ntev, thiab yooj yim tswj. Lub caij nplooj ntoos hlav kev khiav hauj lwm mechanism tuaj yeem khaws lub zog manually lossis hluav taws xob, kaw thiab qhib manually lossis hluav taws xob, thiab muaj lub luag haujlwm rov qab.
3. Cov khoom siv hauv Circuit Court breaker yog welded los ntawm 304 stainless hlau nrog lub thickness ntawm 3 hli. Nws muaj cov qauv airtight tag nrho thiab qib kev tiv thaiv tsis tsawg dua IP67. Muaj qhov yooj yim-rau-saib thiab pom tseeb qhib thiab kaw qhov taw qhia thiab lub zog cia cov xwm txheej ntsuas ntawm lub thawv. Qhov taw qhia muaj kev ntseeg siab txuas nrog lub tshuab ua haujlwm, thiab qhov qhia txog kev ua haujlwm yog txhim khu kev qha. Lub thawv muaj tus nqa nqa kom tsis txhob rub tawm lub cable casing.
