What is the use of film capacitor injection?

The problem of film capacitor immersion is quite biased. I believe many people are not clear. The editor just happened to have a customer to ask this question to understand it carefully. I hope this article can give you some experience and knowledge.

In a customer conversation, the other party asked, “Is there any improvement in power supply noise for CBB capacitor injection? Does your company currently have CBB capacitors?”

What is waxing? When the insulation degree of a certain component of the film capacitor is lowered, the extraordinary heat is inevitably generated, and the internal pressure is increased, so that the film capacitor casing is deformed, expanded, and mechanically displaced to break the explosion-proof wire. Since the power supply is connected to the film capacitor component through the rupture disk, the rupture disk is disconnected equal to the power supply disconnection, thereby leaving the circuit in an open state. The explosion-proof effect is determined by the design of the rupture disk, the mounting position, and the sealing of the film capacitor.

Characteristics of immersion wax film capacitors:

1. Small size and light weight.

2. Excellent electrical performance, low loss, and good self-healing properties.

3. There is a pressure type explosion-proof device inside, which is safe and reliable to use.
