Abstract
The invention discloses a sealing device and a sealing method for a cover plate inner ring of a large-capacity hollow-bolt-type aluminum capacitor. The sealing device comprises an inner sealing base,a double-head inner sealing needle structure and an inner sealing shaft, wherein the inner sealing shaft is mounted on a sealing device, the inner sealing base is mounted at the top end of the inner sealing shaft, and the double-head inner sealing needle structure is fixed on the inner sealing base; the double-head inner sealing needle structure is driven by the sealing device to rotate to seal the cover plate inner ring of the capacitor. The sealing device and the sealing method for the cover plate inner ring which are well designed, based on the double-head inner sealing needle structure andfree of bearings, are quitely precise; the problems of the inner ring sealing of the large-capacity hollow-bolt-type aluminum capacitor can be solved, and the problems that failure of conventional inner ring sealing devices results in production interruption and is hardly to produce in a large scale are solved; meanwhile, the aluminum capacitor produced by the sealing device and the sealing method has very stable electric performance parameters.
Description
technical field [0001] The invention relates to the field of capacitors, in particular to a sealing device and a sealing method for the inner ring of a large-capacity hollow bolt type aluminum capacitor cover plate. Background technique [0002] With the increasing trend of localization of electronic components, the performance requirements for aluminum electrolytic capacitors are also getting higher and higher. Especially the requirements for high temperature, high voltage, large capacity, long life and small volume are more urgent. For example, when a large-capacity bolt-type aluminum capacitor is loaded with high temperature (such as 105 ~ 125°C) and high voltage (such as 400V and above), the central part of the capacitor will generate a lot of heat, and the internal temperature will rise sharply, sometimes far away. Far beyond the rated operating temperature of the capacitor. This will deteriorate the thermal stability of the electrode material, electrolyte and electro...
