Ways to Extend the Life of Capacitors

Ways to extend the life of capacitors
1. Choose high quality capacitors
Capacitors are of poor quality and prone to various failures, thus shortening the life of the capacitors. If a company chooses to use high-quality capacitors, it can greatly reduce the failure rate and increase the actual use time, and it can also be greatly expanded.
2. Avoid overvoltage and overcurrent operation
When the capacitor works with overvoltage, the internal discharge breakdown of the capacitor will increase the loss of the insulating medium of the capacitor, thereby shortening the life of the capacitor; when the power capacitor works with overcurrent, the large current will cause the internal temperature of the capacitor to rise, thus making the capacitor accelerate. Insulation materials thermally age, reducing their useful life. Therefore, when the power capacitor is working, it can be prevented from working due to overvoltage and overcurrent, and its service life can be extended.
3. Make sure the room temperature is right
If the ambient temperature is too high, the thermal aging of the insulation of the power capacitor will be accelerated; if the ambient temperature is too low, the dielectric aging of the capacitor will be accelerated. Therefore, the working environment temperature of the capacitor is suitable, and the service life of the capacitor can also be extended, and the existence of harmonics in the power grid can be controlled in time.
Harmonics can affect electrical equipment, and harmonic sources can also resonate in parallel with capacitors. Therefore, when capacitors are sometimes used with harmonics, harmonic control is required to prolong the life of the capacitors.
