Phase: two phase (a.b 440V)  Rated frequency: 60Hz
Rated output voltage: 1200kV (Three reactor serial connection)
Rated output current: 5A (Three reactors serial connection)
Inductance adjusting range: 4696~723.8H
Load capacitance range: 11053pF@1200kV; 16579pF@800kV; 33158pF@400kV (Include divider)
System overall quality factor: Q>=45 (no water termination and resistance load)
System measuring accuracy: 1grade
System waveform deviation <1%
System noise level: <=70dB (@rated voltage, rated current, 4m distance)
Insulation level: withstanding 1min at 1.1rated voltage.
System running time:
1)one hour on, one hour off@ rated voltage and rated current, 4cycles per day.Continuous working 3hours @ 900kV.
2). Continuous running 20days with load @ 600kV; load capacitance within 13250pF (Two reactor serial connection) Breakdown Test @ 1100kV will not cause damage to the system.
Whole system partial discharge level: <=5pC @100%Un, <=3pC @80%Un (Component PD level will not list separately. The PD test will be conduct at User’s factory after commissioning.)
Protection function: has the function of over-voltage, over-current and test object flashover protection; Reactor max. air gap and min. air gap protection.
Linearity: 10%-100% reactance, error≤±1%
Structure: iron coil structure, user can change the reactance through adjusting open coil gaps, two epoxy tube, the steel bracket is made of stainless material in case of the reducing of quality factor which caused by eddy loss; pedestal has considered the heat which is caused by high-intensity magnetic field; the resonant system designation has considered the expand with heat and contract with cold of the oil.
- Internal structure:
①. 30-Q-130 Grain-Oriented Electrical Steel,
②. There are earthing baffle between winding and iron coil, the earthing is reliable.
③. We do many improment on the system; abandon some unreasonable structure and creat our new resonant. New variable inductance power frequency resonant reactor’s working life not less than 60 years.
④. The iron steel has been done the chip removing treatment. And then form a entirety with curing agent, which lower the noise; equip guide rail between adjustable iron coil and fixed iron coil, to make sure the iron coil move vertical or horizontal. We have been leader of the power frequency variable resonant system, moreover, we cooperate with famous university and research institute and improve ours quality continuously.
