Kev siv cov cuab yeej ntsuas hluav taws xob thib ob kom raug yuav tsum tau ua raws li cov txheej txheem kev khiav hauj lwm tshwj xeeb raws li cov khoom siv los xyuas kom meej qhov ntsuas thiab ua raws li cov cai tswj kev nyab xeeb. Cov hauv qab no yog cov txheej txheem kev khiav hauj lwm rau peb hom khoom siv loj:
Tam sim no Transformer Secondary Load Tester:
Siv rau hauv online ntsuas ntawm qhov tseeb load ntawm CT / PT thib ob Circuit Court yam tsis muaj hluav taws xob cuam tshuam.
Kev xaim thiab Kev Npaj: Txuas cov kev ntsuas hluav taws xob (V +, V-) mus rau qhov chaw nruab nrab ntawm lub tshuab hluav taws xob tam sim no. Siv lub ntsuas ntsuas clamp txhawm rau txhawm rau txhawm rau ntsuas qhov ntsuas hluav taws xob thib ob kom tsis yog- tiv tauj piv txwv, kom ntseeg tau tias lub puab tsaig clamp raug kaw thiab tsis muaj kev cuam tshuam.
Cov kauj ruam ua haujlwm: Tom qab lub hwj chim rau, xaiv "CT Load" lossis "PT Load" hom. Lub cuab yeej cia li hloov qhov ntau thiab cov qauv cov ntaub ntawv. Tom qab ntsuas, nws cia li xam cov tsis xws li impedance (Ω) lossis nkag (mS).
Kev ceev faj: tsis raug clamp meter orientation yuav ua rau kev nyeem tsis zoo; Hauv qhov no, thim rov qab lub clamp meter orientation. Ua ntej kev sim, paub meej tias tsis muaj kev pheej hmoo ntawm qhib Circuit Court (CT) lossis luv luv Circuit Court (PT) nyob rau hauv qhov thib ob Circuit Court.
Secondary Voltage
Tee thiab Load Measurement Instrument Cov cuab yeej no suav nrog kev ntsuas hluav taws xob poob thiab thauj khoom, txhawb kev ntsuas wireless synchronous.
Kev Sib Txuas Txuas / Wireless: Lub tsev tseem ceeb txuas rau lub thawv PT lub davhlau ya nyob twg, thiab cov tub qhe txuas mus rau lub zog ntsuas hluav taws xob. Ib txhij sampling ntawm ob qhov kawg yog tiav los ntawm kev sib txuas lus wireless. Yog hais tias lub teeb liab tsis zoo, lub siab synchronous cable yuav siv tau.
Voltage Drop Measurement Operation: Tom qab pib ua haujlwm, cov cuab yeej synchronously tau txais qhov voltage amplitude thiab theem ntawm ob qho kawg, cia li xam qhov voltage poob feem pua, theem sib txawv, thiab kev ua yuam kev sib xyaw, thiab txiav txim siab seb qhov txwv tsis pub dhau raws li DL / T 448 tus qauv.
Load Measurement: Hloov mus rau hom kev thauj khoom thiab muab cov clamp meter sampling tam sim no los ntsuas qhov ntsuas qhov ntsuas thib ob.
Kev ceev faj txog kev nyab xeeb: Kev siv av ntawm ob lub ntsiab lus ntawm ob sab ntawm qhov hluav taws xob hloov hluav taws xob yog nruj me ntsis txwv tsis pub tiv thaiv luv luv. Tag nrho cov txheej txheem xeem yuav tsum tau ua raws li lub zog muaj zog thiab yuav tsum ua raws li "Kev Cai Tswj Xyuas Hluav Taws Xob".
