The low-voltage power capacitor

In the product adopts a self-healing low-voltage parallel compensation capacitor, and the capacitor uses a qradually thickened zinc aluminum metalized polypropylene film as the dielectric, which has extremely high stability and reliability. in capacitors of the same brand, the larger asingle capacitor, the longer its core components and thicker its diameter. The lenath of the component leadsto an increase in resistance loss, while the thickness of the component leads to a larger surface conductivelayer area and an increase in temperature diference between the inside and outside of the component,making it easier for the conductive layer to detach from the electrode plate. Therefore, using a single largecapacity capacitor in parallel is not as reliable as using a small capacity capacitor, and the number ofswitchina stages of the capacitor can also be effectively increased, At the same time, the capacitor is equipped with a temperature sensor, which reflects the internal heating degree of the capacitor in situationssuch as overvoltage, harmonic, leakage current, and hiah environmental temperature, achieving overtemperature protectior
