A switchgear apparatus includes a vacuum interrupter assembly having a movable contact and a stationary contact, a main housing surrounding the vacuum interrupter assembly, and a first terminal electrically coupled to one of the movable contact and the stationary contact, the first terminal extending from the main housing along a first axis. The switchgear apparatus also includes a second terminal electrically coupled to the other of the movable contact and the stationary contact, the second terminal extending from the main housing along a second axis, and a mounting head couplable to the main housing in a plurality of orientations about the first axis.

Modular recloser

A switchgear apparatus configured for operation at voltages up to 72.5 kV includes a vacuum interrupter assembly having a fixed contact and a movable contact configured to move relative to the fixed contact between a closed position in which the movable contact is in contact with the fixed contact and an open position in which the movable contact is spaced from the fixed contact. The switchgear apparatus also includes an electromagnetic actuator configured to move the movable contact between the open position and the closed position, a manual trip assembly movable from an initial position to an actuated position to move the movable contact from the closed position to the open position, and a mechanical interlock assembly configured to prevent the movable contact from moving from the open position to the closed position when the manual trip assembly is in the actuated position.

Switchgear with manual trip assembly and mechanical interlock

A switchgear apparatus configured for operation at voltages up to 72.5 kV includes a vacuum interrupter assembly including a vacuum bottle having an upper portion and a lower potion, a sleeve surrounding the vacuum bottle, a dielectric material surrounding the sleeve, a first terminal electrically coupled to the upper portion of the vacuum interrupter assembly, and an interchange coupled to a lower portion of the vacuum interrupter assembly. The dielectric material is molded around the sleeve and around at least a portion of the first terminal or the interchange. The sleeve may be molded around the vacuum bottle or pre-formed and slid around the vacuum bottle.

Switchgear with overmolded dielectric material

An integrated assembly includes a switchgear apparatus for operation at voltages up to 72.5 kV and a mount assembly for coupling to a pole and to support the switchgear apparatus. The mount assembly includes a crossbar, a pole mount, a mounting bracket to support the switchgear apparatus, and a pair of crossbar mounts for supporting the mounting bracket on the crossbar at different positions. Each crossbar mount includes a first arm, a second arm spaced from the first arm and extending parallel to the first arm, a third arm extending between and coupled to a distal end of each of the first and second arms, and a flange extending between and coupled to a proximal end of each of the first and second arms. The flange extends parallel to the third arm. The first, second, and third arms and the flange form an enclosed space to receive the crossbar.

Integrated switchgear assembly

Modular switchgear and methods for manufacturing the same. The modular switchgear includes a vacuum interrupter assembly, a source conductor assembly, and a housing assembly. The vacuum interrupter assembly includes a bushing, a fitting, and a vacuum interrupter at least partially molded within the bushing and including a movable contact and a stationary contact. The source conductor assembly includes a bushing, a fitting, and a source conductor molded within the bushing. The housing assembly includes a housing defining a chamber and a drive shaft and conductor positioned within the chamber. The housing assembly also includes a first receptacle for receiving the fitting of the vacuum interrupter assembly and a second receptacle for receiving the fitting of the source conductor assembly. The vacuum interrupter assembly, the source conductor assembly, and the housing assembly are coupled without molding the assemblies within a common housing.
