DC transmission capacitor Capacitor
is a key component of modern variable speed transmission. In static frequency converters used in modern variable speed drives, the switching action of semiconductors generates a lot of spurious signals. Therefore, capacitors are needed in the circuit to filter and eliminate ripples and harmonics. The self-healing metallized film capacitor can be used for DC connection and harmonic filtering of the intermediate circuit. At the same time, it can also be used as a clamping and absorbing capacitor in the control circuit. The capacitor adopts innovative technologies such as safety metallized film, unique flattening and welding processes, advanced shock-proof and voltage- and current-equalizing structural design, which ensures the stability and accuracy of the capacity, low inductance, and greatly improves the resistance to large voltages. , the intensity of the surge. This type of capacitor can be designed into a dry flame-retardant structure or a structure impregnated with high-quality oil under high vacuum to improve the insulation, capacity stability, and life reliability of the capacitor. It also has good heat dissipation function to ensure that the capacitor has a long life. The running of time.
