In the daily operation, we have encountered a lot of problems, and these problems are everyone's attention. The editor of this article will talk to you. If the ceramic capacitor is always powered after breakdown, then the short circuit will be Burned, forming an open circuit?
Breakdown occurs when the voltage strength exceeds the tolerance of the insulator. The current can be directly turned on regardless of the insulator, so it is a short circuit. If there is no protection circuit, the place where the power is always shorted may be blown. It depends on whether the power supply can supply enough current, and also depends on the breakdown of the capacitor (the short-circuit resistance is relatively small).
After the breakdown of the ceramic capacitor, it is equivalent to a short circuit. The reason is that when the capacitor is connected to the DC, it is regarded as an open circuit, and when it is connected to the AC power, it is regarded as a short circuit. The ceramic capacitor has a property of being straight and straight through, and breakdown is performed. The word is understood by the electrician to be a short circuit. The cause of the breakdown is mainly the sexual damage caused by the external voltage exceeding its nominal voltage, called breakdown.
When a destructive discharge occurs in a solid dielectric, it is called breakdown. Upon breakdown, traces are left in the solid dielectric, causing the solid dielectric to lose its insulating properties. If the insulation board breaks down, a hole is left in the cardboard. It can be seen that the term breakdown is used in solid dielectrics.
