AC Resonant Test System Rau Transformer Cable GIS

HMCXZ-88kVA/44kV sib txawv- zaus series resonance unit feem ntau yog tsim los rau AC withstand voltage testing ntawm 10kV cross-txuas cables, tis transformers ntsuas ntawm 6,300kVA los yog tsawg dua, tam sim no transformers, insulators, thiab high-voltage switches

• Qauv / Peev / Voltage HMCXZ-88kVA / 44kV
• Rated Voltage 44kV (ua tau raws li AC tiv thaiv qhov yuav tsum tau muaj rau 63,000kVA fais fab transformers, siab -voltage keyboards, tam sim no transformers, thiab insulators)
• Tawm tswv yim Voltage Waveform Distortion < 1.0%
• Permissible Nruam Lub Sijhawm Ua Haujlwm 30 feeb ntawm kev ua haujlwm tas mus li raws li cov xwm txheej ntsuas; 60 feeb ntawm kev ua haujlwm tsis tu ncua thaum lub sijhawm cable tiv thaiv qhov ntsuas hluav taws xob
• Internal Power Factor Q > 50
• Cable Full -Load Power Factor Q > 30 (load-nyob ntawm)
• Lub zog hluav taws xob ib zaug -theem 380V / 220V
• Kev hloov kho zaus 30 Hz txog 300 Hz
• Kev ntsuas qhov tseeb 1.5%

• Hloov pauv - zaus fais fab mov (4 kW)

Tawm tswv yim: 220/380V ± 15%, 50 Hz; Tawm tswv yim: 0-400V, 30-300 Hz (0.1 Hz increments), Cov zis tam sim no: 0-10 A.

• Reactors (2 units) (DK-44kVA / 22kV)

Ib chav tsev: 22kV / 2A, inductance 55H, qhuav - hom kev tsim kho, muaj peev xwm txhawb nqa tag nrho rau 60 feeb, ua haujlwm kub nce<60°C.

• Excitation transformer (4kVA)

Tawm tswv yim: 220/380V; Cov zis: 1 kV / 3 kV (ob qhov chaw); Cov zis tam sim no: 4 A (1 kV chaw), 1.3 A (3 kV teeb).

• Ob lub capacitive voltage dividers

① 50 kV / 1000 pF; ② 50 kV / 15,000 pF, haum rau 30-300 Hz;
