Rau cov tuam txhab hlau thiab hlau, ua tiav kev txhim kho txuas ntxiv thiab ua tau zoo hauv hlau- ua thiab hlau- ua kom muaj txiaj ntsig tseem yog lub hom phiaj tseem ceeb. Kev vam meej yav tom ntej hauv kev lag luam uas muaj kev sib tw siab heev no yuav yog cov tuam txhab lag luam uas muaj peev xwm ua kom muaj kev ua tau zoo ntawm - kev ua tau zoo, lub zog - txuag, thiab cov txheej txheem tsim khoom huv si. Variable Frequency Drives (VFDs) yog ib qho tseem ceeb thev naus laus zis pab kom ua tiav cov hom phiaj ua haujlwm no.
Thoob plaws ntau theem ntawm steel ntau lawm - suav nrog coking, sintering, moj tej tawg rauv hlau-ua, hluav taws xob arc rauv (EAF) steel-ua, desusting kiv cua, refining furnace ventilators, gas blowers, thiab dej mov twj tso kua mis - RENLE} cov kev pab cuam nruab nrab ntawm lub zog xa tawm {{ kev txuag thiab txo emission.
RENLE nruab nrab-voltage drives pab tswj kom meej ntawm cov kiv cua induction ntim, haum rau cov kev cai tshwj xeeb ntawm txhua theem txheej txheem smelting. Qhov kev ua kom zoo no txo qis thermal dissipation nyob rau hauv hluav taws xob rauv taws, uas ua rau indirect zog txuag. Post- cov ntaub ntawv ua tiav qhia tau hais tias qhov nruab nrab cov cuab yeej siv hluav taws xob txuag tau txog li 26%. Kev txo qis hauv kev siv hluav taws xob tsis yog tsuas yog txo cov nqi smelting xwb tab sis kuj txo cov pa phem ib puag ncig - tsim cov txiaj ntsig zoo rau kev tsim cov hlau thiab kev ua haujlwm.
Pov thawj kev vam meej nyob rau hauv teb
Xyoo 2020, tag nrho ntawm 13 RENLE VFDs - suav nrog 10kV / 220kW × 1, 10kV / 280kW × 1, 3kV / 560kW × 2, thiab 10kV / 710kW × 6 - tau ua tiav txhua xyoo los ntawm Co., Ltd. 250,000 tons. Hom load yog dej twj tso kua mis. Txawm tias nyob rau hauv huab cua huab cua nrog 95% ambient humidity, VFDs tau tswj kev ua haujlwm tsis tu ncua, ruaj khov. Lawv cov khoom zoo tshaj plaws tau txais kev qhuas siab los ntawm cov neeg siv khoom.
Khoom Description
High Voltage Tsav
Ua haujlwm cascaded fais fab xovtooj thev naus laus zis, RNHV 2000 series high voltage tsav ncaj qha tsim 6kV / 10kV tso zis raws li qhov siab -high voltage qhov inverter.
