Main functions thiab nta
Cov kev tswj xyuas ntse yog lub hauv paus tseem ceeb ntawm moldedd case Circuit breaker.Nws yog siv rau hauv kev tiv thaiv lub cev muaj zog lossis kev tiv thaiv hluav taws xob kom paub txog kev sib koom ua ke ntawm kev ntsuas, kev tiv thaiv, kev tswj hwm thiab kev sib txuas lus, kom cov kab thiab cov khoom siv hluav taws xob tuaj yeem tiv thaiv los ntawm overload, luv Circuit Court, grounding thiab lwm yam teeb meem txhaum cai.Siv MCU microprocessor maub los, qhov kev ua tau zoo yog ruaj khov thiab txhim khu kev qha: tus tswj kev txawj ntse tuaj yeem muab lub zog los ntawm nws tus kheej, tsuav yog ib theem muaj zog, thaum tam sim no tsis qis dua 20% ntawm nws cov nqi ntsuas, nws tuaj yeem ua kom muaj kev ua haujlwm zoo ntawm kev tiv thaiv muaj nuj nqi;xaiv kev koom tes muaj peb ntu kev tiv thaiv: Siv lub Circuit Court breaker ntawm chav kawm B thiab lwm yam luv luv-circuit tiv thaiv pab kiag li lawm txuas nyob rau hauv tib lub Circuit Court kom muaj kev xaiv kev koom tes nyob rau hauv luv luv-circuit tej yam kev mob: overload ntev-ntev inverse lub sij hawm, luv-circuit ncua sij hawm (inverse time) , lub sij hawm meej), luv-circuit instantaneous Qhov chaw ntawm kev tiv thaiv muaj nuj nqi tsis;Nws muaj peb-theem kev tiv thaiv parameter teeb tsa ntawm qhov kev txiav txim tam sim no thiab lub sijhawm ua haujlwm, thiab tuaj yeem hloov kho hauv 4-10 cov kauj ruam: tus neeg siv tuaj yeem kho cov chaw tswj hwm raws li qhov xav tau tam sim no, thiab tseem tuaj yeem xaiv kaw cov haujlwm sib xws. raws li tus neeg siv yuav tsum tau (customized functions, yuav tsum tau txiav txim los ntawm tus neeg siv lub sij hawm qhia);Kev ua haujlwm siab tam sim no tam sim no: Thaum lub Circuit Court breaker raug kaw thiab khiav, yog tias ntsib qhov loj luv luv tam sim no (≥201nm), qhov sib nqus tripping mechanism ntawm Circuit Court breaker tuaj yeem mus ncaj qha, thiab kev tiv thaiv ob yog txhim khu kev qha thiab nyab xeeb;Nrog tripping test (test) muaj nuj nqi: input DC12V voltage test Circuit breaker yam ntxwv kev khiav hauj lwm;Kev kuaj tus kheej tsis raug muaj nuj nqi: tiv thaiv thiab kuaj xyuas lub xeev ua haujlwm thiab kev ua haujlwm ntawm tus tswj hwm nws tus kheej;Nrog rau lub tswb ceeb toom ua ntej thiab tshaj qhov taw qhia: thaum lub sijhawm thauj khoom tam sim no mus txog lossis tshaj tus nqi tshaj tawm, nws yog sib npaug rau lub teeb qhia kab kom xa tawm lub teeb ci;Ob chav huab cua sib txawv technology ntawm kev sib chwv-los ntawm kev sib pauv: kev ua haujlwm yog kev txhim khu kev qha thiab ruaj khov, kev ua haujlwm tsis zoo yog zam, kev txav mus los yog txhim khu kev qha, thiab lub zog me me;Kev tiv thaiv siab: kev tiv thaiv overload, luv luv-circuit ncua sij hawm ncua kev tiv thaiv lub sij hawm raug ± 10%;luv-circuit instantaneous tiv thaiv tus nqi raug ± 15% nyob ntawm kev khiav hauj lwm tam sim no;Lub installation muaj qhov sib hloov tau sab nraud, thiab qhov ntev ntawm qhov kev teeb tsa yog tib yam li cov LDM1 series moldedd case Circuit Court breaker.
Nco tseg: JCM3E-M-630 yog tib yam li JCM3E-M-800, raws li JCM3E-M ntse hom kev sib txuas lus lossis hom kev sib txuas lus.
