Description

Technical Field

[0001] This utility model relates to current filters, and more specifically, to a dry 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 fully sealed large-capacity capacitor with application number CN87212920. The application describes the capacitor as a single large-capacity capacitor. Its main features include a fully sealed casing with flexible walls, allowing the casing to expand or contract with temperature changes to compensate for oil volume expansion or contraction. A row of vertical heat dissipation pipes is welded between the upper and lower flanges of the front and rear casing walls, serving to dissipate heat and maintain the casing's shape. The seal between the large ceramic bushing at the outlet and the casing and outlet post uses a double-seal method of rubber gaskets and metal welding. This invention solves the problem of full sealing in large-capacity capacitors and oil leakage caused by aging rubber gaskets, ensuring the safe operation of a single large-capacity capacitor.
