Abstract:
The present invention relates to a high-voltage combined electrical apparatus, comprising a transformer (3), at least one circuit breaker (1), at least one oil/gas separation module (2) and at least one operating mechanism (6), wherein the circuit breaker comprises a ceramic insulator (11), an upper outgoing line seat (111), a lower outgoing line seat (112), and a disconnecting mechanism connected between the upper outgoing line seat and the lower outgoing line seat. The oil/gas separation module has a first end electrically connected to a transformer coil of the transformer, and a second end electrically connected to the lower outgoing line seat. The operating mechanism is connected to and controls the disconnecting mechanism. The high-voltage combined electrical apparatus of the present invention integrates a ceramic column circuit breaker and a transformer, omitting the conventional transformer oil/gas sleeve and overhead line, so that the overall structure thereof is simpler, the cost is lower, the area of ground occupied by the equipment is reduced, and the occurrence of short circuits associated with overhead lines is avoided.
Abstract:

The amount of adsorber m ads arranged in the at least one insulation space compartment complies with the formulae (I) and (II).
Abstract:
The invention relates to an operating device for carrying out switching operations in a switching system (3), especially a medium voltage switching system. Said operating device (1) has an electronic memory card (9) for modifiable storage of the control data (SD), said control data triggering any switching operation automatically. Operation then takes place exclusively via this memory card (9) in that said memory card is inserted into a card-reading device (7) of the switching system (3). The desired switching operations then run automatically by means of an operating program previously stored in the memory card (9).
Abstract:
The invention relates to a switching device for mining purposes, comprising at least one housing, an electrical power component such as a contactor, an electric/electronic control unit and pertaining electrical lines. Renovation or inspection of said switching device can be carried out easily and at low cost. To this end, the housing has at least two housing units, namely a first (1) and a second (2) housing unit. The power component is accommodated in the first housing unit (1). The electrical connection lines to operate the power component are grouped together in at least one multipole connector plug (6a, 6b). The control unit is arranged in the second housing unit (2). The electrical connection lines to operate the power unit are grouped accordingly in at least one multipole socket. The first housing unit (1) has an adapter plate (3) which is provided with the connector plug and the second housing unit has an adapter frame (4) provided with the socket. The second housing unit (2) with the adapter frame (4) can be mounted on the first housing unit (1) with the adapter plate (3) by electrically connecting the connector plug (6a, 6b) to the socket.
Abstract:
A cable management enclosure for providing neat, organized installation of fiber optic or copper cables and providing an easy access for cable maintenance. The cable management enclosure provides an area for managing cabling at the work station area, in a close proximity to the station equipment that includes telephones, data terminals and computers, by providing connection points for two, four or six fiber connectors utilizing slide-in adapter panels. There are also provisions for copper connections with the integration of a single-gang faceplate that can be mounted directly to the cable management enclosure cover (50) to accommodate up to six modular jacks. The base of the cable management enclosure provides incoming fiber cable strain relief plus storage and management of up to one meter of slack for as many as six fibers. The cover (50) snaps onto the base to provide dust-proofing and protection for the fibers. If desired for added security, a concealed cover-to-base screw accommodation may be included. Molded in icon pockets (52) and color-coded, snap-in icons permit fiber port identification.
Abstract:
A switchgear unit (100) includes an enclosure (110) having a front compartment (111) and a rear compartment (112) and a fuse assembly mounted on a wall (122) that separates the front compartment and the rear compartment, the fuse assembly comprising a fuse housing (125) disposed in the rear compartment and accessible from the front compartment via an opening (133) in the wall. The fuse assembly may include a cover (127) configured to separate a fuse (126) in the fuse housing from the front compartment and that is removable to provide access to the fuse from the front compartment. The fuse assembly may further include power input terminals (130) supported by the fuse housing and accessible from the rear compartment and an isolation switch (132) disposed in the front compartment and configured to electrically connect the power input terminal to the upper fuse connection terminal (129).
Abstract:
A switchgear includes a circuit breaker housing defining a circuit breaker compartment. A bushing (22') has first and second portions and extends through an opening (42) in a rear wall (31) of the housing so that the first portion is disposed in the circuit breaker compartment and the second portion is disposed beyond the exterior of the rear wall and external of the circuit breaker compartment. The bushing has a hollow primary contact (50). A current transformer (26') is mounted on the second portion of the bushing. A fastener structure (40) has a portion that extends through the hollow primary contact. The fastener structure couples the primary contact to a busbar in a removable manner. When the fastener structure is decoupled from the primary contact, the bushing and the at least one current transform can be accessed from the front of the housing and moved through the opening in the rear wall, for maintenance.
