HIGH-VOLTAGE CURRENT LIMITING PROTECTIVE DEVICE

摘要

A high-voltage protective device comprising a hollow, generally cylindrical, electrically insulating member having an inner bore. A pair of terminal members is mounted on the insulating member adjacent to the opposite ends. One or more fuse links or fusible elements is disposed in the inner bore and spaced therefrom with each fuse link being connected between the associated terminal members. A finely divided or pulverulent arc quenching material substantially fills the space between each fuse link and the inner bore of the associated insulating member. A supporting means is secured to said insulating member at only one location which is axially intermediate the ends of said insulating member.
