Description

Technical Field

[0001] This utility model relates to current filters, specifically, to a breakdown-resistant, safe dry-type DC filter capacitor. Background Technology

[0002] A filter capacitor is an energy storage device that is often installed at both ends of a rectifier circuit to reduce the AC ripple coefficient and improve the efficiency and smoothness of DC output.

[0003] A search revealed a DC filter capacitor for an auxiliary converter, application number CN202223385354.1. The invention relates to the field of capacitors, and more particularly to a DC filter capacitor for an auxiliary converter. The auxiliary converter DC filter capacitor includes a capacitor body; a fixed frame is fixedly connected to the inner wall of the capacitor body; a top plate is movably connected above the fixed frame inside the capacitor body; and a partition is fixedly connected above the top plate inside the capacitor body. The auxiliary converter DC filter capacitor provided by this invention allows the capacitor body to expand vertically, compressing the top plate inside the capacitor and separating the upper and lower contact pieces above the top plate. This allows the device to promptly disconnect the power to the capacitor body when the voltage is too high.

In addition, the filter has poor voltage transfer capability when subjected to strong current interference, which seriously affects the transmission and transfer of the corresponding filter. Furthermore, the filter has poor breakdown resistance. Utility Model Content
