A film capacitor is a capacitor in which metal foil is used as an electrode, and plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate are overlapped from both ends and then wound into a cylindrical structure. According to the type of plastic film, they are called polyethylene capacitors (also known as Mylar capacitors), polypropylene capacitors (also known as PP capacitors), polystyrene capacitors (also known as PS capacitors) and polycarbonate capacitors.
Different capacitors have their own period of use. When we purchase film capacitors and use them in circuits, what protection measures should we know? This article will talk about the protective measures of film capacitors. Hopefully it is helpful to everyone!
The Protective Measures For Film Capacitors Are As Follows:
1)The voltage of the capacitor needs to be strictly controlled. The voltage of the capacitor usually has its own operating law and should not exceed its rated range, otherwise the temperature of the capacitor will be too high and it will fasten its aging.
2)At the same time, pay attention to the operating temperature of the capacitor. Under normal circumstances, pay attention to the temperature of the shell of the parallel capacitor of the film capacitor. If the temperature is too high, you must find out the specific cause and deal with it in time.
3) Strengthen the patrol and inspection of the film capacitors during use, so as to formulate a regular inspection time period to check whether the housing, mounting brackets, and connection points of the capacitor are firm, if the film capacitor housing is damaged, etc. In case of the situation, the operation must be stopped to avoid accidents. At the same time, attention must be paid to the cleaning and cleaning of dust.
If you want a long service life of film capacitors, then our careful inspection must be indispensable in use. The quality of film capacitors also plays an important role. If you buy inferior film capacitors, there must be no guarantee for their service life. Therefore, when purchasing film capacitors, you still need to find regular manufacturers and purchase them through regular channels.
The protection measures of film capacitors are briefly discussed here. Through the content of this article, do you have a deeper understanding of film capacitors.
