The role of starting capacitor
The role of starting capacitor Simply put, the capacitor is used to generate a phase difference, and the motor magnetic field is "asynchronous", and the motor rotates. A single-phase asynchronous [...]
Maintenance of power capacitors
Power capacitor is a static reactive power compensation device. The maintenance of power capacitors is divided into the following situations: (1) Matters needing attention when handling capacitors Under normal circumstances, [...]
How to solve the damage of reactive power compensation capacitor?
1. The breakdown of the internal components of the reactive power compensation capacitor is mainly caused by poor production technology and overvoltage. Solution: Choose a good quality compensation capacitor and [...]
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 [...]
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 [...]
