Photovoltaic Wind Power DC Filter Capacitor
Dielectric The dc-link photovoltaic DC filter capacitor uses a low-loss metallized film. The self-healing film is a base film and a gradient resistance safety film using evaporation. The film is rolled into a cylindrical shape using fully automated equipment, and non-inductive winding is applied. The thin copper sheet connection method is used in the core, so that the capacitor has a small inductance and strong overcurrent and overvoltage capabilities. Based on long-term use and test results, our capacitor dielectric has good self-healing properties. We use thickening on the edge of the film to increase the edge contact area, so that the contact between the film and the gold-sprayed surface is good, increasing the overcurrent capability of the product and reducing edge stress. Solvent The medium filled in the dc-link photovoltaic DC filter capacitor is to isolate the air. Without the protection of the filling medium, the metal coating will be oxidized, the metallized film will be more and more self-healed, and the capacity of the capacitor will become smaller and smaller. , the loss is getting bigger and bigger. Therefore, when we put the capacitor into an aluminum shell and pour it with polyester, we need to vacuum dry the capacitor to protect the wound core and its surrounding environment, so that the capacitor's capacity is very stable during long-term use. The dc-link photovoltaic DC filter capacitor is filled with polyester, so the capacitor has a high volume utilization ratio, good self-healing characteristics and over-voltage automatic protection characteristics. When an unexpected situation occurs during operation or the capacitor is heavily loaded, , the capacitor will be automatically disconnected to ensure safe operation. Features: Used in DC filter circuits, it can replace electrolytic capacitors The equivalent series resistance is small and can withstand large ripple currents.
