Cov kev teeb tsa ntawm lub tshuab ntsuas hluav taws xob yuav tsum nruj me ntsis sib xws rau hom kev xeem thiab cov kev qhia tshwj xeeb ntawm cov cuab yeej hauv kev sim. Lub hauv paus tseem ceeb yog kom nkag siab qhov ntsuas qhov tseem ceeb, txoj kev sib txuas, thiab ib puag ncig tsis zoo los xyuas kom meej qhov tseeb thiab qhov sib piv ntawm cov txiaj ntsig ntsuas.
General Parameter Setting Principles (tseem siv tau rau txhua hom kev xeem)
Cov ntaub ntawv yooj yim nkag
Rated High/Low Voltage Values: Teem raws li lub npe transformer, hauv kV. Piv txwv li: 10/0.4kV.
Kev Sib Txuas Pab Pawg: Xws li Yyn0, Dyn11, Yzn11, thiab lwm yam, cuam tshuam ncaj qha rau qhov sib piv thiab impedance xam logic.
Coj mus rhaub Hloov Parameters:
Tag nrho cov kais dej
Rated kais txoj hauj lwm (feem ntau yog qhov chaw nruab nrab)
Sib npaug kais theem (qhov hloov pauv theem, xws li ± 2.5%)
Test hom xaiv
Xaiv cov kev ua haujlwm sib raug raws li cov khoom ntsuas: DC tsis kam, hloov pauv, muaj peev xwm, tsis muaj-load / load poob, thiab lwm yam.
Xaiv Hom Khoom Siv Hluav Taws Xob: Ua-hauv Kev Siv Hluav Taws Xob (portable rau kev siv sab nraud) lossis Sab Nraud Voltage Regulator (rau loj- kuaj qhov muaj peev xwm transformer).
Ib puag ncig thiab Calibration Parameters
Test Roj Kub: Ntsuas tam sim no kub ntawm transformer windings, siv rau poob ntaub ntawv hloov dua siab tshiab.
Hloov Kub: Roj-immersed transformer: 75℃Qhuav- hom transformer: 100 degree, 120 degree, los yog 145℃(nyob ntawm tus qauv) Kub calibration xyuas kom meej cov ntaub ntawv sib piv nyob rau hauv txawv kev khiav hauj lwm tej yam kev mob.
Kev Tswj Cov Ntaub Ntawv
Test Number: Ua kom yooj yim rau kev khaws cia thiab traceability.
Sijhawm/Date: Cia li sau lub sijhawm xeem, txhawb kev sib piv cov ntaub ntawv keeb kwm.
