Potential problems with film capacitors
Film capacitors are composed of many basic components. Due to raw materials and manufacturing process, some inexperienced equipment and some small workshops will lead to the hidden dangers of film capacitors. For example, it is easy to have problems such as medium, mechanical damage, pinhole and low cleanliness in production.


These reasons can lead to the short life of thin film capacitors, and easy breakdown. In the system, due to the over voltage, over current and surrounding low temperature caused by various reasons, these film points will cause dielectric breakdown. When the breakdown usually produces spark, further expand the scope, thus forming a multi-layer short circuit or even the entire component short circuit. The voltage on the element in series with the breakdown element will increase accordingly, thus increasing the voltage on the remaining group and the current through each element. Will cause each component to age quickly, increase calorific value.

Note these points when using thin film capacitors
1. The rated voltage of the film capacitor must be consistent with the voltage of the power grid in the region. For some power grids with too high voltage or harmonic, the high harmonic, especially the third, fifth and seventh harmonics, will cause great harm to the power grid.
2. Pay attention to the operating environment temperature. High operating temperature will aggravate the electrochemical reaction of the film capacitor, affect the dissipation of heat during self-healing, and lead to self-healing failure or short service life. Therefore, when installing the film capacitor, the heat source should be avoided to improve the cooling and ventilation environment.
3. The capacitor cabinet shall be provided with reasonable protective devices:
(1) adjust the appropriate delay and discharge time, input and cut capacitor bank with limited current and discharge device. Because the internal resistance of the film capacitor is small, the surge current may be up to tens of thousands of amps. In order to ensure the safe operation and maintenance of the film capacitance, must set up the discharge device;
(2) the casting and cutting procedure shall comply with the principle of first casting and then cutting;
(3) in order to prevent frequent switching, capacitor bank must retain enough capacity when cutting, as the base group.
