With the rapid development of green energy such as rail transit, pure electric vehicles, hybrid electric vehicles, and solar and wind energy, as well as the increasing demand for energy storage, smooth filtering, and large capacity capacitors such as frequency converters, switch mode power supplies, uninterruptible power supplies (UPS), emergency power supplies (EPS), locomotives, ship and warship electric traction drives, high field strength, high energy density, building blocks, compact structures, modularity, personalization, and oil-free, designing specialized products according to different uses and installation requirements will become a trend. Dry oil self-healing low-voltage parallel power capacitors also have excellent sensitivity self-healing properties and can be customized to become the leading product of power capacitors.
The self-healing low-voltage parallel power capacitor has undergone technological improvements on the basis of the original dry-type power capacitor, especially on the metal film of the power capacitor. When any layer of electrode unit in a capacitor is broken down, the charge stored on the capacitor instantly rushes into the breakdown point. When the current reaches the action threshold of the micro fuse, the micro fuse instantly acts, separating the electrode unit where the breakdown point is located from the capacitor electrode as a whole, forming an insulation zone. Due to the ability to control self-healing energy at an appropriate value, the self-healing process is very short and does not affect the dielectric strength of adjacent layers, effectively preventing continuous breakdown and self-healing of capacitors Therefore, accidents such as oil leakage, breakdown, burns, adhesion, and capacitor failures have been solved, ensuring the safety and stability of self-healing low-voltage parallel capacitors in normal use.
The self-healing metal film of low-voltage parallel power capacitors has excellent self-healing performance and safe operation, significantly improving the processing quality, qualification rate, and production efficiency of enterprise production equipment, and is deeply loved by customers.
