Trends in Cbb20 Polypropylene Safety Capacitor

O método usual de fazer capacitores de filme é usar uma folha de metal, como alumínio, como eletrodo e um filme plástico para sobrepor e, em seguida, enrolá-los juntos. Entre todos os capacitores de filme plástico, os capacitores de polipropileno têm as características mais significativas e, claro, o preço desses capacitores é relativamente alto. No entanto, nos últimos anos, a fim de melhorar a qualidade, as peças e os materiais utilizados tornaram-se cada vez mais avançados, e o preço não é o fator mais importante a ser considerado; portanto, nos últimos anos, a frequência e a quantidade de capacitores PP tornar-se cada vez mais alto.

Due to the electrical impedance of a capacitor decreasing with frequency, they are an efficient component for reducing interference because at higher frequencies, they short circuit electrical noise and transients between the lines or to ground. As a result, they shield machinery and equipment from electromagnetic and radio frequency interference as well as transients in across-the-line (X capacitors) and line-to-ground (Y capacitors) connections. This includes motors, inverters, electronic ballasts, solid-state relay snubbers, and spark quenchers. Interference that is symmetrical, balanced, or differential can be successfully absorbed by X capacitors. To counteract asymmetrical, unbalanced, or common-mode interference, Y capacitors are linked in a line bypass between the line phase and a point of zero potential.

We know that Cbb20 polypropylene safety capacitor have a great advantage, that is, they have self-healing properties, that is, if there is a problem inside the capacitor, it can achieve self-healing and can be used normally, but film capacitors also have a disadvantage, that is, film capacitors The capacity will be reduced, especially for the resistance-capacitance step-down circuit. If the quality of the film capacitor is not good, the capacity attenuation will be very serious.
