A winding device for a small and multifunctional capacitor core

Abstract

The invention discloses a small multifunctional capacitor core winding device belonging to the technical field of transformer bushing manufacture. The small multifunctional capacitor core winding device comprises a base, a guide rod mounting mechanism, a tension control mechanism, a paper reel, and a paper reel frame. The guide rod mounting mechanism is mounted on the base, and includes rotating wheels, a handle, a wheel carrier, jaws, fastening toothed belts, and a cross bar. The handle can be rotated to make a guide rod for winding insulating paper rotate with the rotating wheels. The fastening toothed belts can protect the insulating paper and prevent the insulating paper from slipping off under tension. The tension control mechanism is mounted on the base, and includes roller frames, rubber rollers, and bolts used for adjusting the contact pressure and rotation resistance of the rubber rollers. The paper reel and the paper reel frame are used for mounting an insulating paper tray. The winding device has the functions of tension control and paper rolling fixation, has the characteristics of being simple to operate, highly targeted, easy to maintain, and the like, can be used to wind a capacitor core of which the length is less than 200mm and the guide rod outer diameter is 5-20mm, and overcomes the problem that it is hard for a large winding machine to wind a small model.

Description

technical field [0001] The invention belongs to the technical field of transformer bushing manufacturing, in particular to a small and multifunctional capacitor core winding device. Background technique [0002] Transformer oil-paper capacitor bushings are widely used in power grid systems and other power-related equipment. Its operating status directly affects the safe and reliable operation of the power system. In recent years, power accidents caused by bushing failures have occurred frequently, and bushing insulation problems have gradually become a concern in the industry. Attention inside and out. [0003] The capacitor core is the main insulating part of the bushing, and its insulation performance is the key to determine the insulation performance of the entire bushing. The structure of the capacitor core is to wrap a certain thickness of insulating paper layer on the conductive rod, and wrap aluminum foil at a specific position. At present, the rolling device for th...

AI Technical Summary

Problems solved by technology

At present, the rolling device for the capacitor core of the bushing is mainly used for rolling the bushing with a length of more than 1000mm and a conductive rod with an outer diameter of more than 30mm. There is no special small-scale equipment for winding such a small core model.
