Abstract： |
The invention belongs to power device technique field, as non-contact controllable reactor, which separates the dc control winding and ac operating winding in space, uses the adjustable hollow solenoid, the hollow solenoid with variable dc excitation, and the semi-iron core/circular-iron core straight solenoid with dc excitation as control winding. Wherein, regulating the reactance value by changing magnetic flux, controlling the magnetic saturation degree of semi-iron core, and controlling the rotation direction of magnetic domain of circular-iron core in cross magnetic field, improving the nonlinear character of traditional product, reducing harmonic wave quantity and reactor volume. This invention has wide application in power system. |
