Transformer's vector pawg yog kev sib xyaw ntawm cov tsiaj ntawv thiab cov lej uas sawv cev rau kev teeb tsa winding ntawm lub transformer. Cov tsiaj ntawv thiab cov lej no qhia txog tus naj npawb ntawm cov theem pib thiab theem nrab winding, qhov sib txuas winding, thiab theem hloov pauv ntawm thawj thiab theem nrab windings. Pawg vector feem ntau yog qhia hauv cov ntawv, xws li Yyn{{0}}, Dyn11, lossis Z1y0.
Transformer Winding configurations:
D: Delta kev twb kev txuas
Y: Wye(star, Y) txuas
Z: Zigzag (z) kev sib txuas.
N: Nruab nrab point muaj
Phase Displacement
Sawv cev los ntawm tus lej (0 mus rau 11), txhua qhov qhia txog 30-degree theem hloov pauv, nruab nrab ntawm qhov pib thiab theem nrab windings.
Ib qho cuab yeej siv feem ntau rau kev sim ntsuas transformers yog lub transformer tig ratio tester. Qhov ntsuas no yog siv los txiav txim siab qhov sib piv ntawm lub tshuab hloov pauv, uas yog qhov piv ntawm tus lej ntawm cov lem hauv thawj winding mus rau tus naj npawb ntawm lem nyob rau hauv lub thib ob winding. Qhov sib piv no yog qhov tseem ceeb hauv kev ua kom ntseeg tau tias lub transformer muab qhov tseeb voltage tso zis raws li qhov sib txawv load.
IEC 60076-1 tus txheej txheem thoob ntiaj teb txhais cov cim vector pawg, cov txheej txheem kuaj, thiab tso cai rau kev hloov pauv rau lub zog hloov hluav taws xob thoob ntiaj teb. Wuhan Huayi fais fab fais fab thev naus laus zis tab tom ua rau lub tshuab hloov pauv hloov pauv ntsuas (TTR meter), nws tuaj yeem sim transformer Vector pab pawg tau txais.
Transformer vector pawg yog qhov tseem ceeb hauv kev ua haujlwm kom raug thiab kev tiv thaiv ntawm transformers hauv cov tshuab fais fab. Nkag siab txog pawg vector yog qhov tseem ceeb rau kev qhia, kev sim, thiab kev khiav hauj lwm fais fab transformers kom zoo thiab nyab xeeb. Transformer tig ratio tester yog ib qho cuab yeej tseem ceeb hauv kev txiav txim siab qhov sib piv ntawm cov hloov pauv, uas yog qhov tseem ceeb hauv kev ua kom lawv cov haujlwm zoo.
