Suggestions for handling the failure of audio film capacitors

Many people want to buy a good sound, but they don't know how to find a good sound. When choosing an audio, they may be worried. In fact, we can choose the right sound when we pay attention to one thing, that is, the audio film capacitor. . The sound quality of an audio playback is mainly determined by the film capacitor. Although the audio film capacitor is very resistant to damage, if it is damaged, we should repair it in time. Otherwise, our good sound will be completely If we can't play a good role, how do we save our audio capacitors?

When there is a common fault in the audio film capacitor, such as when you hear an abnormal sound inside, and then the temperature of the case rises sharply, and the audio film capacitor expands, we should cut off the power immediately to avoid each In an unexpected situation, if you don't know how to deal with it, you may have a worse situation if you do it indiscriminately. Then we have found that the fault has occurred or the fault has occurred. How do we deal with it?

The first is to check and conduct a series of tests. Don't try it easily until you reach a conclusion, because we probably don't have the key points. At this time, it is easy to try without any change. In the case of overhaul, there is a separate discharge due to the short-circuit relationship between the two poles, so it is necessary to wear insulated gloves. In general, fault conditions are high ambient temperature, unstable voltage, and the presence of harmonic current. To prevent these from happening, a hollow reactor can be serially connected in each phase of the compensation capacitor bank to control the current. The resultant reactance of the capacitor circuit becomes an inductive reactance for higher harmonics.

The material of the audio film capacitor will affect the quality and performance of the product. In the process of use, it will inevitably lead to the cause of the malfunction. We must know how to deal with it. We also need to know what the situation is. It will be solved and prevented next time, but don't try it easily. Contact and repair, the result will inevitably be worse.
