The cause of the early damage of the capacitor(III)

In this case, the protective fuse relay relay cuts off the fault capacitor in time, and if it cannot be removed, further breakdown will form a strong arc in the enclosure. Other shunt capacitors and system energy will cause the capacitor dielectric to rapidly age and expand in a very short period of time, eventually causing the enclosure to expand, and in severe cases it will explode. This type of accident cannot be eliminated by the user. It belongs to the early damage of the capacitor and the period is usually about one year. As a manufacturer of capacitors, we must pay attention to quality and strengthen inspection methods in order to reduce the early damage rate.
