6 FAQs about [Capacitor element winding structure]

What are the factors affecting the performance of capacitors?

The main factors influencing the performance of capacitors are polypropylene resin, polypropylene film, metallization coating process and capacitor winding process.

Should metallized film capacitors be winded?

Therefore, it is urgent to explore the winding process suitable for high-voltage metallized film capacitors and improve the performance of metallized film capacitors, which is of great significance for improving the independent innovation ability of high-end power equipment and ensuring the national energy strategic security [9, 10].

What causes electrical breakdown of a capacitor?

The electrical breakdown of a capacitor most commonly begins with the initiation of corona or partial discharge. When the voltage across the plates of a capacitor dielectric system is raised, a level is reached where a multitude of partial discharges begin to occur at a consistent voltage level.

Are temperature distributions of a power capacitor correct?

To validate if temperature distributions of a power capacitor in 4 cases are correct, the running temperatures on the surface of capacitor body and shell are adopted respectively, when the capacitor reaches steady state. The results are shown in Table 4, and the results which are obtained by numerical simulation are compared with the test values.

How does inrush current affect power capacitor switching?

Simulation model of power capacitor switching The inrush current is a major switch‐on transient phenomenon of the power capacitors, and it will shorten the operation life of the power capacitors and damage the contactors of the switching devices, so it is essential to restrict the inrush current.

How can a switching case reduce the hazards of power capacitors?

To reduce the hazards of such switching, a new switching case of power capacitors is proposed, and the comparisons for inrush currents and transient voltages in different switching cases are obtained by numerical simulation and real‐time digital simulator.
