摘要： An electrical enclosure includes a housing having a front, a back, a plurality of sides, a plurality of sections disposed between the sides, at least one electrical apparatus, and a plurality of electrical bus members electrically connected to the electrical apparatus. The electrical apparatus is disposed within a first one of the sections of the housing, and a substantial portion of the electrical bus members are collectively disposed within a second one of the sections of the housing. At least the second one of the sections and the substantial portion of the electrical bus members collectively disposed therein are accessible from the front of the housing, regardless of whether the electrical apparatus is within or removed from the first one of the sections of the housing. An electrical bus assembly is also disclosed.

摘要： An electrical system and a sensor for on-line monitoring of the state of high-voltage insulation in the electrical system. In this arrangement, the signals associated with partial discharge activity are monitored and transmitted from the sensor to monitoring instrumentation. The sensor is interconnected with the potential stress shield of existing bushings. The capacitance in the bushing between the main conductor and the stress shield conducts partial discharge current which is available for being sensed.

摘要： Fuses for the potential transformers (PTs) in medium voltage switchgear are mounted in fuse assemblies which are reciprocated within the switchgear enclosure independently of the transformers they protect between a connected position in which the fuse assemblies engage stabs at the rear wall of the enclosure and a retracted position adjacent a door at the front of the enclosure through which the fuses are inserted and removed while the fuse assemblies remain within the enclosure. The fuse assemblies include insulative tubes having first releasable contacts at a distal end which engage the stabs and second releasable contacts which engage fixed contacts connected to the transformers and spaced from the rear wall. The insulative tubes are mounted on a carriage which reciprocates between the connected and retracted positions. An interlock prevents opening of the door except where the carriage is in the retracted position and blocks movement of the carriage with the door open. The carriage can be alternatively turned over so that it can serve a transformer mounted over or under the fuse assembly, or two units, one having a connection facing upward and the other having its connection facing downward, can be inserted between an upper and lower transformer.

摘要： A maintenance-free electrical bus assembly is provided for a switchgear cabinet. The maintenance-free electrical bus assembly is coupled to a switchgear device in the cabinet, and includes electrical bus members, at least one bus joint comprising an electrical connection of two or more electrical bus members, and a fastener assembly fastening the bus joint and maintaining the electrical connection between the electrical bus members thereof. The fastener assembly includes at least one first fastening element having a plurality of first threads, and at least one second fastening element having a plurality of second threads. The second threads threadably engage the first threads of a corresponding first fastening element, in order to perpetually secure the first threads and the corresponding first fastening element, and to resist undesirable loosening of the bus joint once the fastener assembly has been fastened. Thus, inaccessible bus joints within the cabinet do not need to be inspected.
