Clamp-on ammeter rau hluav taws xob tub sab nyiag thiab xau kuaj
Clamp ammeter yog cov cuab yeej siv hluav taws xob zoo tshaj plaws rau kev ntsuas cov kab hluav taws xob tsawg, siab precision thiab kev ruaj ntseg zoo yog nws cov yam ntxwv tseem ceeb. Cov neeg ua haujlwm fais fab tuaj yeem siv los kuaj xyuas qhov hluav taws xob tsawg, micro-tam sim no thiab xyuas cov khoom siv xau, sim cov kab tseem ceeb seb puas muaj hluav taws xob tub sab. Kab lus no qhia txog lub clamp-on ammeter los kuaj xyuas lub zog tub sab nyiag kom pom
Tshawb xyuas kab hauv thiab cov khoom siv nrog lossis tsis muaj hluav taws xob to
Nyob rau hauv txoj kab tseem ceeb nrog lub clamp-on ammeter los ntsuas qhov xau tam sim no, thiab tom qab ntawd cov khoom siv hluav taws xob yuav raug kaw nyob rau hauv lem, txhua qhov kaw nrog clamp-on ammeter txhawm rau txheeb xyuas cov kev hloov pauv ntawm cov kab xau tam sim no kom pom cov khoom xau. Yog tias tag nrho cov khoom siv hluav taws xob tau raug kaw lawm, tab sis lub clamp-on ammeter qhia tau hais tias tseem muaj cov xau tam sim no, yuav tsum muaj cov kab hluav taws xob tsawg tsawg, yuav tsum tau hloov dua tshiab lossis cov ntsiab lus to kom pom.
Txiav txim siab seb theem twg ntawm cov theem kab xau
Nyob rau hauv lub tis transformer, disconnect tus nruab nrab kab ntawm lub contactor sab ntawm lub low-voltage kab, tshem tawm lub fuse thiab nruab rau hauv ib qho ntawm cov theem kab, thiab siv lub clamp-on ammeter los ntsuas theem, thiab ntsuas tam sim no. yog qhov xau tam sim no ntawm theem. Ntsuam xyuas cov xau tam sim no ntawm lwm cov kab hauv lem
Txiav txim siab qhov chaw ntawm qhov xau
Nyob rau hauv cov ntaub ntawv ntawm low-voltage kab energized, nrhiav pom ntawm ib-theem kab thiab nruab nrab kab yuav tsum tau muab tso rau hauv lub puab tsaig ntawm lub clamp-on ammeter nyob rau tib lub sij hawm, peb-theem peb-theem kab thiab nruab nrab kab yuav tsum. kuj muab tso rau hauv lub puab tsaig tib lub sijhawm. Yog tias tsis muaj qhov ua txhaum cai, ces qhov load tam sim no flux ntawm theem thiab xoom, clamp ammeter qhia kuj yog xoom; xws li to tam sim no, lub clamp ammeter tuaj yeem ntes tam sim no to.
Ceev faj:
Nrhiav qhov txhaum cai yuav tsum tau xyuam xim rau kev nyab xeeb, kom muaj kev nyab xeeb ntawm tib neeg lub cev thiab cov khoom siv hluav taws xob.
Cov hluav taws xob xaim, xoom kab clamped ua ke uas yog ntsuas qhov xau tam sim no ntawm cov khoom siv hluav taws xob. (Yuav tsum tau xyuam xim rau 2)
Cov kab hauv av clamped los ntsuas qhov xau tam sim no ntawm cov khoom siv hluav taws xob hauv av. (Yuav tsum tau xyuam xim rau ib leeg)
Clamp peb-theem plaub xaim ua ke los kuaj tag nrho cov xau tam sim no. (4 kab)
Clamp txoj kab tseem ceeb los ntsuas qhov tam sim no ntawm txoj kab tseem ceeb. (Nco ntsoov tias ib leeg)
