[0002] Power capacitors are capacitors used in power systems and electrical equipment. Any two metal conductors separated by an insulating medium constitute a capacitor. The capacitance of a capacitor is determined by its geometric dimensions and the characteristics of the insulating medium between the two plates. When a capacitor is used under AC voltage, its capacity is often expressed in terms of its reactive power, in units of var or kilovar.

[0003] Capacitor is a component that can store electric charge. It is one of the electronic components used in large quantities in electronic equipment. It is widely used in circuits for DC isolation, AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, control, etc. It is an indispensable and important component in people's lives. At this stage, there is a shortage of labor in my country. In order to reduce labor costs and improve work efficiency, the automated production of capacitors has become particularly important.
