MACHINE WITH HIGH VOLTAGE ENCLOSURE COVER

摘要

A machine includes a high voltage element and an enclosure surrounding the high voltage element. The enclosure includes a first wall formed of an electrically conductive material, a first insulating insert disposed at least partially within the first wall and being electrically non-conductive, a first conductive insert at least partially disposed within the first insulating insert, and an enclosure cover formed at least partially of an electrically non-conducting substrate and having a first opening formed therein sized to allow a first fastener or an extension of the first conductive insert to pass through it. The substrate includes a first conductor terminating at a first location at or near an edge of the first opening and a second conductor terminating at a second location at or near an edge of the first opening and separated from the first location. The first and second conductors are electrically coupled to one another through the first conductive insert when the enclosure cover is placed into contact with the first conductive insert and electrically isolated from one another when the enclosure cover is at least partially removed from contact with the first wall.
