Problems solved by technology

However, when the existing polypropylene film capacitors are used under high-frequency or high-pulse conditions, the pulse current passing through the capacitor will cause the capacitor itself to heat up and the temperature will rise, resulting in problems such as increased self-healing points, reduced withstand voltage, and shortened life. Afterwards, it is easy to age, the working performance is reduced, and it will lead to the occurrence of electric shock when the capacitor fails

Abstract

The invention discloses a metalized polypropylene film anti-interference resistance-capacitance module comprising a capacitor, a resistor, a first pin, a second pin, resin and a shell. The capacitor is connected in series with the resistor. The capacitor and the resistor are arranged in the shell. The resin fills between the shell and the capacitor and the resistor. One end of the capacitor is welded to the second pin. One end of the resistor is connected with the first pin. The first pin and the second pin extend to the outside of the shell. According to the metalized polypropylene film anti-interference resistance-capacitance module, the occasion of electric impact in case of failure of the capacitor does not occur.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to a metallized polypropylene film anti-interference resistance-capacitance module. Background technique [0002] Film capacitors use metal foil as an electrode, which is stacked with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and wound into a cylindrical capacitor; in all Among the plastic film capacitors, the characteristics of polypropylene (PP) capacitors are the most significant. Capacitors made of polypropylene film have the advantages of low heat shrinkage, stable performance, high temperature resistance, high pressure resistance, and prevention of breakdown. The use range of the prepared capacitors is getting wider and wider. The capacitor core is the heart of the capacitor. Therefore, the material of the capacitor manufacturing core must have a polymer film that can withstand high frequency, high temperature, and high current i...
