Khoom Taw Qhia
HMCXZ-16875kVA/225kV Variable-Frequency Series Resonance Test System yog tsim thiab tsim los rau AC tiv thaiv qhov ntsuas hluav taws xob ntawm 69kV, 138kV, thiab 230kV fais fab cables thiab lub zog hluav taws xob. Qhov thib plaub - tiam AC no tiv taus qhov ntsuas hluav taws xob resonance chav ntsuas muaj 32-ntsis RISC CPU nrog LINX core thiab 7-nti muaj tseeb-xim touchscreen.
Qhov system feem ntau muaj cov khoom hauv qab no:
- Hloov pauv - zaus tswj fais fab mov (CHXB-700kW / 0.38kV)
- Excitation transformer (JLB-450kVA / 2/4 / 6kV)
- Siab -Voltage Reactors (DK-5625kVA / 75 ~ 225kV, 3 seem tag nrho)
- Capacitive Voltage Divider (FCR-250kV / 1000pF)
- Resonance Compensation Capacitor (XZC-75 ~ 225kV / 25000 ~ 75000pF)
Technical parameter ntawm tag nrho cov kev xeem system
- Rated muaj peev xwm: 16875kVA
- Input fais fab mov: peb-theem 380V voltage, zaus 60Hz
- Kev ntsuas hluav taws xob: 225kV
- Rated tam sim no: 75A
- Ua haujlwm zaus: 20-300Hz
- Waveform distortion tus nqi: tso zis voltage waveform distortion tus nqi Tsawg dua los yog sib npaug rau 1%
- Duration: Cia tas mus li 60 feeb nyob rau hauv rated load (60 feeb ntawm kev ua hauj lwm thiab 60 feeb ntawm so)
- Kub nce: Tom qab ua haujlwm tas li rau 180 feeb nyob rau hauv qhov ntsuas load, qhov kub nce qis dua lossis sib npaug rau 65K
- Qhov zoo tshaj plaws: Ntaus Q Ntau dua lossis sib npaug rau 30 (f=45Hz)
- Kev tiv thaiv muaj nuj nqi: Nws muab cov overcurrent, overvoltage, thiab cov qauv flashover tiv thaiv rau cov khoom xeem (saib qhov sib txawv zaus fais fab mov seem kom paub meej)
- Kev ntsuas qhov tseeb: System RMS 1.5 qib
- Ua haujlwm ib puag ncig:
- Kub: -15 ℃ -45 ℃
- Tus txheeb ze humidity: Tsawg dua los yog sib npaug rau 90% RH
- Qhov siab: Tsawg dua lossis sib npaug li 2500 meters
