Embodiment Construction
[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0039] A method for designing a residual magnetic mechanism of a recloser is characterized in that silicon steel materials are used as the material of the magnetic circuit of the residual magnetic mechanism of the recloser, and the specific steps include:
[0040] 1) The yoke is made of silicon steel; a cavity is set in the yoke, and a closing coil is set in the cavity; a through hole is set in the middle of the bottom of the cavity;
[0041] 2) A moving iron core is set in the middle of the closing coil, and the moving iron core is used to drive the pull rod; an elastic body is set in the middle of the closing coil, and the elastic force of the elastic body on the moving iron core is opposite to the magnetic force of the moving iron core after the closing coil is energized. Control the movement of the moving iron core in the axial direction of...
