How to choose power capacitor?

At present, there are many power capacitor manufacturers, and there is a trend of bad money washing good money, so this article analyzes the power capacitor product, and provides reference for us to choose products.

When purchasing power capacitors, we can't simply look at the price and brand. Only with good basic materials, advanced production process design, excellent production equipment and perfect testing equipment system can we guarantee good products.

These will directly determine the main performance of power capacitor: self-healing, over-current and over-voltage ability, explosion-proof, whether it can adapt to the humid, salt fog, high altitude environment. In selecting power capacitor products, we need to pay attention to the following points:

In selecting power capacitor products, we need to pay attention to the following points:

Whether the product test report is obtained, whether it has good self-healing function, whether it has explosion-proof function, how to solve the capacitance loss, the selection of filling medium, production equipment and testing equipment.

Test report is the basic requirement of product circulation in the market and the basic guarantee of product quality. If there is no test report, it will be regarded as fake and shoddy product. You should remember to ask for the test report when you buy it.

In addition, the power capacitor must have self-healing characteristics, that is, it can recover itself in case of abnormality, rather than quit work in case of abnormality. The products made of metallized film have self-healing function. Only high-quality metallized film can guarantee the quality of power capacitor.
