HCRS 350kV/700kVA Inductance Resonant Reactor

Mode: HCRS 350kV/700kVA
Structure: cylinder type, inductance continuous adjustable.
Single phase  Frequency: 50Hz
Cooling methods: ONAN  Single module
Rated capacitance: 700kVar  Rated output: 350kV
Rated current: 2A  Rated impedance: 140kΩ
Rated current adjusting range: 0.33 -2.5A
Rated load capacitance range: 3000pF-23000pF
Rated reactance adjusting range: 140KΩ-1060KΩ
Waveform deviation: ≤1%  Quality factor: >40
Over-current capability: continuous working 3min under 110% rated current, not cause any damage to ractor winding.  Over-voltage capability: working 300s under 110% rated voltage (385kV), not cause any damage to insulation.
Partial discharge: less than 10pC under rated voltage
Linearity: 1%-100%, impedance 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.
