Power capacitor core winding equipment and control method and system of stepping motor of power capacitor core winding equipment

Abstract

The invention discloses power capacitor core winding equipment and a control method and system of a stepping motor of the power capacitor core winding equipment. The winding equipment comprises two metal foil roll mounting mechanisms, a plurality of insulating film roll mounting mechanisms, a merging mechanism and a core winding mechanism. The core winding mechanism comprises a flat plate-shaped reel mechanism arranged under the merging mechanism, and when the flat plate-shaped reel mechanism rotates, metal foils and insulating films output by the merging mechanism can be wound around the flat plate-shaped reel mechanism. A winding roll wound on the flat plate-shaped reel mechanism is of a flat plate-shaped structure, and when the winding roll is pressed into a flat plate structure, the metal foils and the insulating films can be effectively prevented from wrinkling in the pressing process. According to the control method and system for the stepping motor and the stepping motor of the core winding mechanism controlled by the system, it can be guaranteed that when the flat-plate-shaped winding shaft mechanism conducts winding, and the pulling tension of the metal foils and the pulling tension of the insulating films are balanced, so material damage caused by the metal foils and the insulating films in the winding process can be avoided.

Description

technical field [0001] The invention relates to the field of power capacitors, in particular to a power capacitor core winding device and a control method and system for a stepping motor thereof. Background technique [0002] With the rapid development of social economy, users in the grid market have put forward higher requirements for the high-quality operation of the power system. The power capacitor plays an irreplaceable role in the voltage support, reactive power compensation and harmonic filtering of the power grid. Therefore, it is required to strictly control its manufacturing process to ensure the stability of its performance in all aspects. The smallest component unit of a power capacitor is a core formed by winding multi-layer aluminum foil and polypropylene film, so the first step in ensuring the capacitor manufacturing process is to ensure that the core is made with high quality and high standards to meet the requirements of various indicators. [0003] The cor...

Problems solved by technology

Due to the direct pressing from the cylinder to the flat plate, it is often impossible to avoid the inner aluminum foil or polypropylene film wrinkles during the flattening process

The wrinkles of aluminum foil or polypropylene film will not only affect the uniformity of the capacitor core structure, but also easily accumulate residual charges, resulting in distortion of the electric field in the polypropylene film, which not only reduces the insulation performance of the capacitor, but also aggravates the vibration of the capacitor, causing strong noise , reducing the environmental friendliness of the entire capacitor
