What factors affect the life of low-voltage power capacitors?

Low-voltage power capacitors are the key equipment in distribution reactive power compensation, and power capacitors are a very "soft" component, which will reduce the service life of power capacitors under the influence of environmental conditions. Here is a summary of several factors that affect the life of low-voltage power capacitors. 1. temperature. The capacitor will generate [...]

Reasons for the popularity of self-healing capacitors

The self-healing capacitors uses a single-layer polypropylene film as the medium, and a thin layer of metal is vapor-deposited on the surface as a conductive electrode. When an excessively high voltage is applied, the electrical weakness of the polypropylene film is broken down, the resistance of the breakdown point is significantly reduced, and the current density [...]

How to test whether the capacitor is inserted reversely

Whether the capacitor is inserted reversely can be detected by image recognition or ICT For capacitors with polarity, such as electrolytic capacitors, tantalum capacitors, etc., it is absolutely not allowed to plug them in reverse. If they are plugged in reverse, they will fail or even burst. In the production of circuit boards, it is very [...]
