HZDK-1000 1000A DC Hloov Ampere-Second Characteristic Tester

I. Txheej txheem cej luam

Tam sim no, DC feeder network ntawm lub substation feem ntau siv cov qauv ntoo. Los ntawm lub roj teeb mus rau cov khoom siv hluav taws xob hauv qhov chaw nres tsheb, nws feem ntau mus txog peb theem ntawm kev faib hluav taws xob, thiab txhua theem ntawm kev faib hluav taws xob feem ntau siv DC Circuit Court breakers ua cov cuab yeej tiv thaiv. Vim yog qhov tsis sib haum xeeb ntawm kev tiv thaiv kev ua haujlwm ntawm lub sab sauv thiab sab qis DC Circuit Court breakers, thaum lub voj voog luv luv tshwm sim hauv cov khoom siv hluav taws xob qis thaum lub sijhawm ua haujlwm ntawm DC system, nws feem ntau ua rau DC Circuit Court breaker ntawm qib siab mus txawv tebchaws, yog li ua rau hluav taws xob tawm hauv lwm cov kab noj khoom noj, thiab tom qab ntawd ua rau muaj kev sib tsoo hauv cov khoom siv tseem ceeb ntawm lub substation xws li high-voltage switches, transformers, capacitors, thiab lwm yam. Circuit Court breakers thiab lwm yam khoom siv tiv thaiv DC, Lub Xeev Grid Corporation ntawm Tuam Tshoj tau teev tseg tias qhov kev ntsuas ampere-thib ob yuav tsum tau ua rau cov khoom siv tshiab thiab ua haujlwm DC tiv thaiv kom ntseeg tau tias qhov kev ua tau zoo raws li tus qauv tsim, kom paub meej. qhov tseeb ntawm DC Circuit Court sib txawv kev sib koom ua ke. Nqe 12, nqe 8 ntawm "DC Fais Fab Kev Ua Haujlwm Specifications"tshaj tawm xyoo 2005 tau hais tias "DC fuses thiab cov hluav taws xob hluav taws xob yuav tsum yog qhov tsim nyog, thiab lawv cov fuses lossis cov chaw yuav tsum tau muab qhab nia thiab hloov kho raws li cov kev cai cuam tshuam, thiab tshuaj xyuas tsis tu ncua los tiv thaiv kev sib tsoo los ntawm kev nthuav dav vim kev ua haujlwm tsis raug"; Tshooj lus 27 ntawm "DC Fais Fab Kev Tswj Xyuas Kev Tswj Xyuas Cov Cai" stipulates: "... tsis siv neeg cua Circuit Court breakers yuav tsum raug kuaj xyuas ntawm cov yam ntxwv thiab kev khiav hauj lwm tam sim no ua ntej siv ..."; Tshooj 11 ntawm "Kev ntsuas tiv thaiv kev raug mob hauv DC Fais Fab Systems" stipulates: "... chaw kuaj xyuas ntawm ampere-thib ob yam ntxwv thiab kev khiav hauj lwm tam sim no yuav tsum tau ua ua ntej siv ..."

Cov yam ntxwv ntawm ampere-thib ob ntawm DC cov cuab yeej tiv thaiv feem ntau yog kuaj hauv lub teb chaws kuaj lossis chaw kuaj. Cov cuab yeej siv nyob rau thaj tsam loj thiab yuav tsum muaj lub tshuab them nyiaj tshwj xeeb thiab lub thawv ntim siab tam sim no, uas yog qhov nyuaj rau kev khiav lag luam. Qee qhov chaw ua haujlwm siv cov roj teeb substation los ntsuas qhov sib txawv ntawm kev sib koom ua ke ntawm DC cov cuab yeej tiv thaiv, tab sis tsis tuaj yeem kuaj xyuas lawv cov yam ntxwv tam sim no-ua haujlwm. Yog li ntawd, tom qab DC lub kaw lus tau muab tso rau hauv kev ua haujlwm, cov neeg ua haujlwm saib xyuas hauv qhov chaw tsis tuaj yeem txheeb xyuas seb puas yog ampere-thib ob tus yam ntxwv ntawm DC tiv thaiv cov cuab yeej ua tau raws li qhov yuav tsum tau ua vim tias lawv tsis muaj cov txheej txheem kuaj thiab cov cuab yeej sib raug.

Raws li qhov teeb meem tiag tiag ntawm ampere-thib ob tus yam ntxwv kev sim ntawm DC tiv thaiv cov cuab yeej, peb lub tuam txhab tau tshaj tawm DC Circuit Court breaker ampere-thib ob tus yam ntxwv kuaj system uas tsim nyog rau kev siv ntawm qhov chaw hauv substations, nqa tau yooj yim, thiab ua haujlwm siab heev. Nws tuaj yeem muab cov haujlwm ua haujlwm thiab kev saib xyuas nrog rau kev kuaj xyuas cov yam ntxwv ntawm DC tiv thaiv cov cuab yeej, thiab ntsuas cov yam ntxwv ntawm kev ua haujlwm thiab kev sib koom ua ke ntawm DC tiv thaiv cov cuab yeej, txhawm rau txhim kho kev ntseeg siab ntawm DC kev ua haujlwm thiab xyuas kom muaj kev nyab xeeb thiab txhim khu kev qha. kev ua haujlwm ntawm daim phiaj fais fab.

HZDK-1000DC Circuit Court breaker ampere-thib ob tus yam ntxwv xeem system yog tsim rau ampere-thib ob yam ntxwv xeem ntawm DC Circuit Court breakers nrog ib tug ntsuas tam sim no ntawm 1A rau 1000A, thiab yuav siv tau rau ampere-thib ob yam ntxwv xeem ntawm DC fuses nrog ib tug ntsuas tam sim no ntawm 6A rau 150A.
