In many cases, when there is a problem with the chip capacitor, we don't know whether we can continue to use it, whether we can repair it, whether we should stop using it, because we are not professionals. Many times, we will encounter such a situation, that is, when the chip capacitor can be repaired, we will stop using it, sometimes we should stop using the chip capacitor immediately, resulting in the final loss of the wife and break the army, next, understand what circumstances should stop the chip capacitor, and the safety precautions when dealing with the fault.

1. When the chip capacitor is found to have one of the following conditions, the chip capacitor should be removed immediately to stop operation:

1, the chip capacitor shell expansion or internal media seepage;

2, the insulation terminal is broken or the surface has burnt marks;

3. The sound inside the chip capacitor is abnormal;

4, the shell temperature is higher than 65 ° C, the temperature sheet falls off;

5. The capacitor current of the patch is significantly reduced.

2. Safety precautions when dealing with faulty chip capacitors:

1. When dealing with faulty chip capacitors, the isolation switch should be disconnected after all capacitors stop running, which is easy to cause damage to the arc of the isolation switch; Because the shell may be charged after the capacitor fails, wait 3 minutes before touching the capacitor, and use a wire to short-circuit the discharge at the outgoing end of the capacitor, and ensure that there is no remaining power supply in the capacitor.

2. After replacing the capacitor, clean up the oil stains left over from the original old capacitor to facilitate the operation and observation of the new capacitor;

3, the wire tightening should be properly tightened to avoid excessive force to damage the terminal or tighten enough to cause poor contact and burn the terminal;

4, if there is an unconfirmed situation when dealing with the faulty capacitor, please consult the manufacturer's technicians and other professionals for blind treatment, resulting in greater failure.
