Khoom Taw Qhia

Rau peb theem a. c. cov cav tov, 50 Hz lossis 60 Hz, npaj los txuas ncaj qha rau kev faib khoom lossis kev siv tshuab, cov ntsuas hluav taws xob yuav tsum tau muab los ntawm cov nominal voltages muab hauv IEC 60038.

CEEB TOOM Rau qhov loj high-voltage a . c. cov cav tov, cov voltages yuav raug xaiv rau kev ua tau zoo. Rau ib. c. cov tshuab txuas nrog cov hloov pauv zoo li qub cov kev txwv ntawm qhov voltage, zaus thiab waveform tsis siv. Hauv qhov no, qhov ntsuas hluav taws xob yuav tsum raug xaiv los ntawm kev pom zoo. Rau cov tshuab hluav taws xob nrog hom I rwb thaiv tsev raws li IEC 60034-18-41, uas yog tsim tshwj xeeb rau cov khoom siv hluav taws xob los ntawm cov khoom siv hluav taws xob, cov chaw tsim khoom tuaj yeem muab cov chav kawm hluav taws xob hluav taws xob hluav taws xob (IVIC) raws li IEC 60034-18-41 rau rwb thaiv tsev system. Hauv qhov no, cov txheej txheem rwb thaiv tsev yuav tsum tsim nyog rau IVIC C rau theem - rau - theem thiab IVIC B rau theem - rau - hauv av lossis raws li kev pom zoo ntawm tus neeg siv thiab cov chaw tsim khoom. Qib IVIC yuav tsum muab rau hauv cov ntaub ntawv thiab nyiam dua ntawm daim ntawv teev npe (saib 10.2).

NOTE For more information on special considerations for converter fed machines , see IEC TS 60034-25. Any bus transfer or fast reclosing of an a . c . machine , as it might occur , for example , due to the voltage ride through requirements of grid codes , can lead to very high peak currents endangering the stator winding overhang and to a very high peak torque of up to 20 times rated torque endangering the mechanical structure including the coupling and the driven or driving equipment . Bus transfer or fast reclosing is therefore only allowed if specified and accepted by the manufacturers of electric machine and driven equipment . For ratings s 10 MW or MVA , slow reclosing exceeding 1.5 times the open circuit time constant is allowed , if specified and accepted by the manufacturers of the electric machine and the driven equipment . For ratings >10 MW lossis MVA, qhov tsawg kawg nkaus tso cai rau lub sijhawm rov qab qeeb yuav tsum tau txiav txim siab los ntawm kev soj ntsuam ib ntus ntawm kev ua tiav los ntawm cov txheej txheem kev sib koom ua ke thiab raug tso cai yog tias tau txais los ntawm cov tuam txhab ntawm lub tshuab hluav taws xob thiab cov khoom siv tsav.
