Static charge discharge device and static charge discharge procedure

摘要

static discharge device (1, 2, 3, 4, 5) having all of the following:-a charger (20) with one or more charging units (21, 22, 23); anda grounded needle-shaped ladder (30), where the charger (20) is designed to charge an insulating film (11) by contacting the insulating film (11) in such a way that the absolute surface potential of the insulating film (11) is three kV or more;where each of the load units (21, 22, 23) has a role (21b, 22b, 23b) which is covered by an insulating element (21a, 22a, 23a) with a level in the triboelectric range other than that of the insulating foil, the insulating element (21a, 22a, 23a) being formed around a surface (12, 13) contact the insulating foil (11), andwhere the needle-shaped conductor (30) is positioned to produce a coronal discharge between the insulating film (11) charged by the charger (20) and the needle-shaped conductor (30).
