Txoj Cai Ua Haujlwm ntawm Delta Kev Sib Txuas
Kev sib txuas delta zoo ib yam li muab lub tshuab nqus tsev twj tso kua mis nrog peb -ceev gearbox: peb -theem windings txuas kawg - mus rau -kawg los ua ib lub voj kaw, nrog rau txhua qhov winding ncaj qha mus rau cov kab hluav taws xob. Qhov kev teeb tsa no tso cai rau cov windings kom tau txais kev ua haujlwm siab dua, ua rau nws tshwj xeeb tshaj yog haum rau cov ntawv thov uas xav tau ntau qhov pib torque.
Voltage yam ntxwv: Winding Voltage=Kab Voltage (piv txwv li, 380V)
Cov yam ntxwv tam sim no: Kab tam sim no=1.73 × Phase tam sim no
Daim ntawv thov: Siab- lub zog tsav (7.5 kW thiab siab dua)
Scenario tsim nyog rau txoj kev sib txuas no
Kev sib txuas delta yog qhov kev xaiv zoo tshaj plaws rau koj lub tshuab nqus tsev twj nyob rau hauv cov xwm txheej hauv qab no:
Pib nyuaj: Thaum siab load inertia xav tau ntau dua pib torque
Voltage Stability: Cov kev lag luam ib puag ncig muaj cov yam ntxwv ntawm cov kab hluav taws xob siab thiab ruaj khov
Kev Ua Haujlwm Nruam: Cov kev ua haujlwm uas yuav tsum tau muaj kev txhawb nqa siab - lub zog tso tawm dhau lub sijhawm txuas ntxiv
Energy Efficiency Optimization: Txhawm rau zam qhov poob ntawm kev ua haujlwm hauv lub teeb loads feem ntau cuam tshuam nrog lub hnub qub kev sib txuas
Kev txiav txim siab ua haujlwm tseem ceeb
Kev siv txoj kev sib txuas no zoo ib yam li kev tsav tsheb phau ntawv - kis tau tus mob lub tsheb - nws yuav tsum tau saib xyuas tshwj xeeb rau cov ntsiab lus hauv qab no:
Winding Inspection: Xyuas kom meej tias cov nqi hluav taws xob tsis zoo tshaj 5 MΩ
Kev Taw Qhia Kev Tshawb Fawb: Manually tig lub ncej ua ntej lub zog los xyuas qhov xav tau ntawm kev sib hloov
Kev tiv thaiv overload: Ib qho tsim nyog thermal overload relay yuav tsum tau ntsia
Thermal Management: Saib xyuas cov cua kub thaum lub sijhawm ua haujlwm kom paub tseeb tias lawv tsis pub tshaj 80 degree
Hloov Kev Nyab Xeeb: Thaum siv lub Hnub Qub-Delta pib, teem sijhawm hloov pauv ncua sijhawm ntawm 2 txog 5 vib nas this
