Cov qauv kuaj thiab cov lus qhia tshwj xeeb rau cov hloov pauv tam sim no (CTS) yog lub hauv paus ntawm lub zog rau kev tiv thaiv kev tiv thaiv, thiab cov khoom muaj kev nyab xeeb. Lawv npog cov ntsiab lus tseem ceeb xws li cov qhab nia zoo, kev txwv yuam kev, cov khoom kuaj, thiab cov qauv kev sim.
Txheem rau raug
Kev ntsuas raug cov qauv raug rau kev ntsuas CT:
Ntsuas qib ib txwm (0.1, 0.2, 0.5, 1 qib);
Cov qhab nia tshwj xeeb (0.2s, 0.5s qib):
Tsawg precision theem (3, 5 qib)
Xeem raug cov qauv raug rau kev tiv thaiv CT;
Nrog cov kev ua yuam kev sib xyaw ua yuam kev raws li qhov taw qhia tseem ceeb, cov qib qib yog 5p thiab 10p. Piv txwv li, ntawm qhov ntsuas ntsuas qhov tseeb tam sim no, cov kev sib xyaw ua yuam kev ntawm qib 5p yog tsawg dua lossis sib npaug nrog rau qhov ua yuam kev tam sim no, qhov kev ua yuam kev tam sim no tsawg dua lossis sib npaug ± 1%.
Tam sim no hloov pauv cov khoom lag luam thiab cov qauv kuaj
Kev Xeem Yuam Kev: Siv cov tshuaj sib txawv sib txawv (xws li 5%, 20%, 100%) siv cov qauv tam sim no. Ntsuas cov kev ua yuam kev tam sim no thiab theem sib txawv uas siv cov cuab yeej ua kom zoo, thiab xyuas kom lawv ua tiav qib kev txwv tseeb.
Rwb thaiv tsev tiv thaiv: Siv ib qho kev ntsuas Ohmark los ntsuas cov rwb thaiv tsev tsis kam ntawm cov windings thiab hauv av, zoo li ntawm cov windings lawv tus kheej. Feem ntau, nws yuav tsum muaj ntau dua los yog sib npaug rau 1000 mω (tshwj xeeb yog cov khoom siv hluav taws xob)
AC withstand voltage kuaj: Thov muaj ntau zaus voltage (piv txwv li, 3kv rau 1 feeb) rau cov windings, uas tsis muaj kev puas tsuaj los yog tawg penomena.
DC kev ntsuam xyuas ntawm windings: ntsuas cov nqi tiv thaiv ntawm theem nrab winding, nrog kev sib txawv ntawm kev siv tus nqi, kom ntseeg tau tias qhov kev xav ntawm cov windings.
