Background
The gap adjustable reactor realizes the adjustable inductance of the reactor by changing the size of the air gap between the iron cores, which puts forward a lot of requirements on the processing of the iron cores. The iron core can produce the diffraction magnetic circuit at iron core section edge after pulling open the clearance, and the bigger diffraction magnetic circuit scope that the air gap is big more, and the diffraction magnetic circuit can produce the iron core piece and appear the magnetic field and run through, appears eddy current loss at the position of running through and lead to the local overheat of iron core and the production of iron core noise.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a gap-adjustable reactor iron core structure to solve the central problems of the prior art.
The technical scheme of the utility model is as follows: a gap-adjustable reactor iron core structure comprises a static iron core, a movable iron core and a positioning adjusting mechanism;
the static iron core and the movable iron core respectively comprise an iron core column and a side yoke iron core;
the positioning adjusting structure comprises a preset nut, a pull screw and a fixing component; the preset nut is arranged in the iron core column, the pull screw rods are respectively arranged in the static iron core and the movable iron core, and the fixing component is fixedly connected with the pull screw rods.
Further, the core limb by a plurality of core pieces stack dress form, the core limb on establish the hole and place the nut that presets, nut and core piece glue and annotate as an organic whole in advance.
Furthermore, one end of the pull screw rod is connected with the preset nut, and the other end of the pull screw rod is connected with the fixing component.
Furthermore, an insulating tube is arranged outside the pull screw rod.
Furthermore, the fixing assembly comprises a base plate, a belleville spring and a fixing nut, one end of the pull screw penetrates through the base plate to be connected with the belleville spring, and the fixing nut is used for fixing the belleville spring and the base plate.
The utility model has the beneficial effects that: the iron core column and the side yoke iron core are positioned by pulling the screw rod, and then the iron core column and the side yoke iron core are fixedly formed by the base plate, the disc spring and the fixing nut, so that the problems that the magnetic field diffraction magnetic circuit of the adjustable reactor iron core influences the iron core, the loss of the reactor iron core and the noise are reduced, and the like are solved.
