Taw qhia rau lub hauv paus ntsiab lus ntawm kev tawm coil

Cov kab hluav taws xob tawm yog cov khoom siv feem ntau siv hauv cov khoom siv capacitor. Lub qhov hluav taws xob kawg ntawm qhov hluav taws xob xa hluav taws xob txuas nrog rau qhov sib npaug rau ob qhov hluav taws xob kawg ntawm lub txhab nyiaj capacitor. Thaum lub sij hawm ib txwm ua hauj lwm, nws bears lub voltage ntawm lub capacitor bank. Nws qhov thib ob winding qhia txog qhov kev hloov pauv thawj zaug, thiab qhov tseeb feem ntau yog 50VA / 0.5 qib. Nws tuaj yeem ua haujlwm ntev ntawm 1.1 npaug ntawm qhov ntsuas hluav taws xob. Nws qhov thib ob winding feem ntau txuas rau hauv daim duab peb sab qhib lossis theem voltage sib txawv los muab kev tiv thaiv rau sab hauv ntawm lub txhab nyiaj capacitor (PT ntawm lub busbar tsis tuaj yeem siv). Qhov qhib daim duab peb sab voltage tiv thaiv thiab tsis sib npaug voltage tiv thaiv ntawm lub txhab nyiaj capacitor yog qhov kev tiv thaiv zoo li no. Thiab hom kev tiv thaiv no yog siv dav hauv 6kV ~ 66kV ib leeg Y-txuas capacitor cov tsev txhab nyiaj raws li qhov xav tau ntawm GB-50227.
Qee lub sij hawm qhov paug tawm yog hloov los ntawm qhov tso tawm PT. Txawm hais tias tus capacitor paug siv lub tshuab hluav taws xob los yog lub tshuab hluav taws xob hluav taws xob feem ntau nyob ntawm lub peev xwm ntawm lub capacitor. Feem ntau, lub peev xwm me me (<1.7Mvar) capacitor bank can be discharged with a voltage transformer, and a large-capacity capacitor bank (≥1.7Mvar) must use a discharge coil, otherwise it will cause the voltage transformer to burn or explode.
