Vim li cas theem nrab voltage ntawm voltage transformer 100V thiab 100/3V?

Hauv cov tshuab hluav taws xob,voltage transformers(PTs) muaj qhov sib txawv nruab nrab voltage qhov tseem ceeb, xws li 100V thiab 100 / √3V, uas muaj feem xyuam rau cov txheej txheem hauv av thiab hom kev ntsuas hluav taws xob.

• Rau qhov nruab nrab ntawm qhov nruab nrab hauv av ncaj qha (cov tshuab hauv av siab tam sim no), peb -theem peb- winding tsib-limb voltage transformers lossis peb ib zaug -theem voltage transformers txuas nrog hauv Y0 / y0 / Δ configuration feem ntau yog siv.
• Thaum thawj kab hluav taws xob yog nyob ntawm nws tus nqi ntsuas, cov kab hluav taws xob theem nrab yog 100V. Piv txwv li, yog hais tias tus thawj kab voltage yog 10kV, tom qab lubvoltage transformerpiv yog hloov dua siab tshiab, theem nrab kab voltage yog stabilized ntawm 100V. Qhov no yog siv los txuas cov cuab yeej ntsuas, cov cuab yeej tiv thaiv, thiab lwm yam, uas yuav tsum tau muaj kab hluav taws xob ntawm 100V, ua kom yooj yim rau cov cuab yeej no tsim thiab ua haujlwm raws li cov qauv voltage.

• Hauv qhov nruab nrab nruab nrab nruab nrab, qhov nruab nrab theem voltage yog 100 / √3V. Txij li kev sib raug zoo ntawm kab hluav taws xob thiab theem voltage yog Ul=3Uph, thiab kab hluav taws xob paub tias yog 100V, theem voltage yog 100 / √3V. Hauv kev ntsuas thiab kev tiv thaiv circuits, qee cov khoom siv yuav tsum muaj cov teeb liab theem voltage, thiab cov nqi hluav taws xob theem nrab no tuaj yeem ua tau raws li lawv cov kev ua haujlwm.
• Rau qhov nruab nrab -point ungrounded system (tsawg-tam sim no grounding system), thaum ib zaug - theem av txhaum tshwm sim, qhov voltage ntawm faulty theem poob mus rau xoom, thaum lub voltage ntawm cov tsis yog -faulty theem nce mus rau kab voltage. Lub sijhawm no, qhov tso zis voltage ntawm qhib delta winding ntawm lubvoltage transformeryog 100V, thaum lub sij hawm ib txwm voltage ntawm ob sab yog 100 / √3V. Qhov no yog vim hais tias nyob rau hauv ib txwm ua haujlwm, peb -theem voltages yog symmetrical, thiab theem voltage yog 100 / √3V tom qab transformer voltage transformer. Thaum ib qho -theem hauv av txhaum tshwm sim, 100V cov zis tawm los ntawm qhov qhib delta winding tuaj yeem siv los tsim cov cuab yeej ntsuas hluav taws xob txhawm rau txheeb xyuas qhov ua txhaum hauv av hauv qhov system.
• Secondary sab ntawm avoltage transformermuaj ib tug winding nrog ib tug tso zis voltage ntawm 100/3V, uas yog residual voltage winding ntawm PT. Hauv peb-theem PT, sab theem nrab txuas nrog hauv qhov qhib qhov kev teeb tsa rau kev tiv thaiv relay thaum muaj xwm txheej hauv av.
