Circuit Court ua haujlwm tso
Pib npaj: nias lub khawm SB2, contactor KM coil yog energized, KM nquag qhib tus neeg pab tiv tauj thiab cov neeg sib txuas tau raug kaw, ib txwm qhib kev pabcuam tiv tauj kaw kaw KM coil yog hluav taws xob tus kheej ntsuas phoo, KM lub ntsiab tiv tauj raug kaw raws li inverter Hloov lub zog loj Cov.
Kev sib hloov mus rau pem hauv ntej: nias sab nraud hloov SA ntawm STF lub davhlau ya nyob twg ntawm inverter, STF thiab SD cov kab txuas txuas nrog, uas yog sib npaug rau STF cov davhlau ya nyob twg nkag thiab cov lus qhia rau pem hauv ntej kev sib hloov tswj teeb liab. Cov inverter U, V, W terminals tso zis rau pem hauv ntej kev hloov fais fab voltage, thiab lub zog tsav yog qhov zoo. Khiav. Kho lub zog ntawm potentiometer R sab nraum lub davhlau ya nyob twg, inverter tso zis hluav taws xob zaus yuav hloov, thiab lub cev muaj zog nrawm tseem yuav hloov.
Kev tiv thaiv tsis meej inverter: Yog tias tsis meej lossis yuam kev tshwm sim thaum lub sijhawm khiav ntawm lub inverter, sab hauv sib npaug kaw qhov chaw hloov pauv ntawm B thiab C cov kab ntawm cov inverter raug txiav tawm, KM coil ntawm lub contactor yog de-energized, KM lub ntsiab tiv tauj raug txiav tawm , thiab lub tswv yim inverter raug txiav tawm. Lub zog muab los tiv thaiv inverter.
Nres kev tswj: Thaum lub inverter ua haujlwm zoo li qub, qhov hloov SA raug txiav tawm, STF thiab SD cov haujlwm kawg raug txiav tawm, lub inverter nres tso tawm zog, thiab lub cev muaj zog nres.
