The invention provides a damping device and an electric reactor. The damping device is applied to the electric reactor, and comprises a groove and a magnetic conduction winding, wherein the groove isformed in one end face of a pair of butt joint end faces of the electric reactor; the magnetic conduction winding is wound on the groove and the side wall of one end face of an iron core to form an annular structure; and the magnetic conduction winding divides the end face into a first part not wound by the magnetic conduction winding and a second part wound by the magnetic conduction winding. Themagnetic conduction winding is embedded into the end face of the electric reactor iron core, so that electromagnetic force generated by the magnetic conduction winding and the original electromagnetic force act together, the effect of reducing vibration of the iron core is achieved, and the vibration problem of the electric reactor is further solved.
Description
technical field [0001] The invention relates to the technical field of UHV DC transmission power equipment, in particular to a vibration damping device and a reactor. Background technique [0002] The anode saturable reactor is a key device in the converter valve, which is used to protect the reliable opening of the thyristor. However, the anode saturable reactor is subjected to pulse voltage when the converter valve is turned on or off, and the transition of its core between magnetically unsaturated and magnetically saturated states is generally completed within a few microseconds to tens of microseconds. Therefore, the working current of the anode saturable reactor contains a large number of harmonics. These harmonic currents will aggravate the vibration of the iron core. The higher the current frequency, the sharper the vibration noise will be, which seriously affects the life of the reactor and the overall noise level of the valve hall. Therefore, the saturated reactor ...
