Abstract

The invention relates to the technical field of power, in particular to an open iron core structure of an inductance-adjustable resonant reactor. The open iron core structure comprises an outer cylinder, wherein the outer cylinder is a cylinder with two sealed sides, the bottom of the outer cylinder is fixedly connected with the base, a handle is fixedly connected with one side, far away from the base, of an outer wall of the outer cylinder, a line pack is fixedly connected with the top of an inner cavity of the outer cylinder, a guide cylinder is inserted into an inner cavity of the line pack, an iron core is arranged in an inner cavity of the guide cylinder, a screw rod is inserted into the inner cavity of the guide cylinder, and a screw rod sleeve is in threaded connection with one end, near to the iron core, of the lead screw. By the open iron core structure of the inductance-adjustable resonant reactor, the function of adjusting inductance is achieved, a large magnetic sensing force does not exist between irons during the adjustment process, the single iron core which is employed is relatively small in magnetic leakage, the iron core loss is low, the output power of the whole equipment is improved, and the comfortableness of a user is enhanced; and moreover, the whole structure is relatively small in size, the total weight of the whole equipment is reduced, and the noise generation quantity is relatively small during inductance adjustment.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an open core structure of a tuned resonant reactor. Background technique [0002] The traditional tuned resonant reactor adopts the closed iron core structure and principle of "mouth or yue" to adjust the inductance. Usually the iron core is divided into two parts: "fixed iron core and moving iron core". The coil and the "fixed iron core" are fixed. By adjusting the position of the "moving iron core" in the coil, the purpose of adjusting the magnetic induction is achieved to obtain the change of inductance. . This method adjusts the inductance, the magnetic induction force between the "fixed iron core" and the "moving iron core" is large, and the magnetic flux leakage is also large during the adjustment process, which will inevitably increase the magnetic induction force vibration noise, increase the magnetic flux leakage loss at the same time, and reduce the use efficie...
