Safety capacitor is a common capacitor. There are safety certification marks of various countries on the safety capacitors, indicating that the safety capacitors have passed the inspections of authoritative organizations in various countries and meet safety standards.
The difference between safety capacitors and ordinary capacitors is that after the power is turned off, ordinary capacitors still have charge inside, and people will get an electric shock if they touch it, which increases the risk of electric shock. However, after the safety capacitor is disconnected from the power supply, the internal charge quickly dissipates, so it can reduce the risk of electric shock. It can be said that the safety capacitor is the guardian of the power circuit and protects the personal safety of the user.
Safety capacitors are mainly used in DC power filters, coupling capacitors of isolation transformers, filtering of input and output terminals of switching power supplies, insulation of DC bus and ground, etc. It can remove clutter and improve the stability and reliability of the circuit while ensuring the normal operation of the circuit.
What is the impact on the circuit after the safety capacitor is damaged?
The circuit clutter increases; the circuit stability decreases, affecting normal operation; the circuit insulation becomes poor; resulting in problems such as circuit failure to start and abnormal sound.
The safety capacitor is an indispensable part of the circuit. Once the safety capacitor is damaged, it will affect the normal operation of the circuit and cause circuit failure. Therefore, when using safety capacitors, pay attention to the quality of the safety capacitors. If the safety capacitors are damaged, they should be replaced in time to ensure the stability and reliability of the circuit.
