The reason for the explosion of the safety capacitor appears here

Today, there is a customer consultation editor: "Why does the capacitor burst? We have a burst of capacitors purchased in other homes. The quality of your capacitors is no problem. Will this happen?" Edit here I want to Say, the capacitor bursting is not new, and there are many reasons for this, but the quality of the safety capacitors we produce is no problem. Let's talk about the cause of the capacitor bursting.

1) The quality of the safety capacitor is not enough. This editor believes that everyone will understand that the safety capacitor is a safe capacitor and is certified. When you buy a safety capacitor, you can consult the manufacturer for the certificate number to ensure that the capacitor you purchased is of quality assurance. Quality can also be subdivided into poor sealing, internal free, damage to the insulation of the enclosure, and so on. Manufacturing processes and materials can also lead to the quality of safety capacitors, so when purchasing safety capacitors, choose a manufacturer with quality assurance.

2) With charge closing. If the polarity of the voltage at the moment of closing is exactly opposite to the polarity of the residual charge on the capacitor, the addition of the two voltages will generate a large inrush current in the loop, which may cause overheating to burst. Therefore, each time the capacitor bank is closed, it must be performed after the breaker disconnects the capacitor for 5 minutes.

There are several reasons for the explosion of the safety capacitors. In summary, the quality and human manipulation are improper and the humans are not properly used. We must pay attention to it.
