Abstract
The invention discloses a low-noise low-loss self-saturation reactor and a manufacturing method. The reactor comprises a single-arm iron core, a control winding and a mounting frame, the single-arm iron core is mounted on the mounting frame, and the control winding is arranged on the single-arm iron core; the single-arm iron core is formed by stacking a plurality of ellipse-like iron core cakes; a shock pad is arranged between every two adjacent ellipse-like iron core cakes; shock pads are arranged at the top of the ellipse-like iron core cake at the topmost end and the bottom of the ellipse-like iron core cake at the bottommost end; the iron core is provided with a polyester belt used for tightening the ellipse-like iron core cake and the shock pad. According to the invention, the ellipse-like iron core cake is adopted, the use amount of silicon steel sheets is reduced, and meanwhile, the damping pad is arranged and the iron core cake is tightened by the polyester tape, so that the noise during operation is effectively reduced; besides, the insulating base is made of special insulating materials, and the glass fiber reinforced plastic screw and the glass fiber reinforced plastic nut are used, so that eddy-current loss of copper bar current on the insulating base of the reactor is eliminated, and operation loss is reduced.
