HFRS 750kV/4500kVA Variable Frequency Resonant Reactor

Mode: HFRS 750kV/4500kVA
Three modules
The three modules can be serial connected or parallel connected.
Single module rated voltage: 250kV,
Single module rated capacitance: 1500kVar
Rated current: 6A         Single module inductance: 150H±2%

Insulation Level: 
Single module withstand voltage: 275kV/1min
Pedestal to ground: 30kV/5min
Working frequency range: 30-300Hz
Rated frequency: 44Hz
Quality factor: Q>80(@44Hz)
Partial discharge level: ≤10pC @ rated voltage.
Working time: Running time requirement: continuous working one hour @ rated power.
Temperature raise: winding≤80K, transformer oil≤55K; Surface of epoxy tube temperature raise ≤40K

Structure Requirement: 
The system adopts iron coil subsection air gap and copper winding structure, reactor adopts copper lead-wire winding, oil immerse self-cooling, oil tank is iron shell structure to increase the system heat dissipation capability, and equips with breathe capsule for transformer oil expanding when testing. Reactor equips reliable hook for suspending.
The inner structure of the reactor is special designed for long distance railway, highway transportation. The system suitable for on-site test.
Reactor has nameplate for single unit and serial connection: the parameter on nameplate are: Rated voltage, inductance, working frequency, weight, and so on.
Compared with Epoxy tube type structure, the Metal tank structure has better function on heat dissipation. And Tank structure has better performance on on-site testing.
