Film capacitor, film capacitor element, aging apparatus for film capacitor element, and aging method

摘要

Provided are a device and a method capable of definitively executing, in a shorter period of time, a thermal aging treatment on a film capacitor element. The present invention is configured in a manner such that: a diaphragm (62) is provided inside a storage chamber (46); a vacuum chamber (66) and a compressed-air chamber (68) for storing a film capacitor element (10) are formed inside the storage chamber (46) on both sides of the diaphragm (62) so as to sandwich the same; a restricting means (70) for restricting the positional shift of the film capacitor element (10) to the diaphragm (62) side is further provided inside the storage chamber (46); exhaust means (82, 86) are provided which create a vacuum state inside the vacuum chamber (66); compressed-air supply means (84, 88) are further provided which supply compressed air into the interior of the compressed-air chamber (68), and shift the diaphragm (62) toward the vacuum chamber (66); and the interval between the diaphragm (62) and the film capacitor element (10) housed in the vacuum chamber (66) is provided with a deformation prevention means (90) for preventing the curving deformation of the gap-forming site of the film capacitor element (10), and positioned so as to be capable of shifting in position.
