Test lub sij hawm yuav tsum tau rau dynamic yam ntxwv tester ntawm high-voltage switchgear

Lub high-voltage hloov dynamic yam ntxwv tester (circuit breaker analyzer) yog dav siv rau lub sij hawm ntsuam xyuas ntawm Circuit Court breakers, CB timed testing, hloov yam ntxwv ntawm SF6 switchgear, GIS ua ke hluav taws xob, lub tshuab nqus tsev keyboards, roj keyboards thiab kem keyboards, hu, thiab lwm yam .
Cov kev xeem tshwj xeeb thiab zaus yog raws li hauv qab no:
1. Lub sij hawm ntsuas: tsis tsawg tshaj li lub sij hawm kaw ntawm lub Circuit Court breaker, nrog rau kev daws teeb meem ntawm 0.01ms;
2. Lub sij hawm ntsuas qhov yuam kev: hauv 200ms ± 0.1ms, siab dua 200ms ± 2%;
3. Synchronization lub sij hawm ntsuas yuam kev: Lub sij hawm synchronization ntawm tus tester yuav tsum tsis pub tshaj ± 0.1ms;
Thaum ntsuas qhov kaw thiab qhib lub sijhawm ntawm lub tshuab hluav taws xob, lub sijhawm sib txawv ntawm qhov kaw lub hwj chim thiab qhov qhib hluav taws xob yuav tsum tau teeb tsa:
Lub sijhawm qhib thiab kaw S1= lub sijhawm kaw + tsis muaj lub sijhawm kaw tam sim no
Lub sijhawm kaw S2=Lub sijhawm kaw + Lub sijhawm luv luv rau kub
Ntawm lawv, lub sijhawm qhib thiab lub sijhawm kaw yog ntsuas ua ntej. Cov chaw tsim hluav taws xob hloov hluav taws xob tsis muaj qhov sib txawv tam sim no thiab lub sijhawm luv luv ntawm cov hlau, thiab lub sijhawm teeb tsa yuav tsum tsawg dua li cov nqi teev tseg (yog tias tus qauv tsis muaj qhov sib txawv tam sim no yog 300ms, nws tuaj yeem teeb tsa) li ntawm 280ms; Yog hais tias lub sij hawm luv luv ntawm cov hlau yog 60 milliseconds, nws tuaj yeem teem rau ib ncig ntawm 50 milliseconds.
Kev soj ntsuam thiab ua cov ntaub ntawv xeem rau High Voltage Switch Dynamic Characteristics Tester
1. Cov txiaj ntsig kev xeem yuav tsum tau muab piv nrog cov txiaj ntsig tau muab rau hauv phau ntawv qhia txog kev sib tsoo hluav taws xob thiab yuav tsum ua raws li cov neeg tsim khoom xav tau;
Yog tias muaj cov ntaub ntawv xeem hauv qhov kev sim uas tsis ua raws li cov neeg tsim khoom yuav tsum tau ua, ua ntej xyuas seb puas muaj cov kab hluav taws xob, qhov ntsuas qhov ntsuas, thiab cov ntsuas ntsuas raws li qhov yuav tsum tau ua;
Thaum lub sijhawm qhib tsis tau raws li qhov kev xav tau tshwj xeeb, qhov ua tau yog: ua ntej, txoj hauj lwm ntawm qhov qhib electromagnet sab saum toj pas nrig thiab qhib qhov hloov tsis tsim nyog; Qhov thib ob, kuv nkees ntawm lub caij nplooj ntoos hlav; Thib peb, qhov qhib qhov deb lossis overtravel tsis ua raws li qhov yuav tsum tau ua. Raws li cov chaw tsim khoom cov kev xav tau, kho qhov pib electromagnet, qhib thiab kaw lub caij nplooj ntoos hlav, thiab lub tshuab txuas txuas;
Thaum lub sijhawm kaw tsis tau raws li tus qauv yuav tsum tau ua, cov laj thawj tshwm sim yog: thawj zaug, lub sijhawm qhib thiab kaw ib leeg tsis ua raws li tus qauv yuav tsum tau ua; Thib ob, lub Circuit Court breaker kev khiav hauj lwm mechanism muaj tripping kev ua tau zoo. Raws li kev txheeb xyuas tag nrho ntawm cov laj thawj saum toj no, kho lub sijhawm qhib thiab kaw ib leeg lossis lub sijhawm tso tawm raws li cov chaw tsim khoom tsim khoom;
Thaum qhov tseem ceeb ntawm lub sijhawm sib txawv tsis ua raws li tus qauv yuav tsum tau muaj, cov laj thawj muaj xws li: ua ntej, qhov kev ncua deb ntawm peb-theem qhib tsis sib xws; Qhov thib ob, lub sij hawm electromagnetic nkaus ntawm cov txheej txheem sib cais tsis sib haum. Cov laj thawj saum toj no yuav tsum tau txheeb xyuas kom meej. Kev ua haujlwm ntawm electromagnet, qhib thiab kaw lub caij nplooj ntoos hlav, thiab lub tshuab txuas txuas yuav tsum tau hloov kho raws li cov chaw tsim khoom cov kev cai.
