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.
