An apparatus includes a housing, a first plurality of gas-insulated circuit interrupters in the housing and a second plurality of gas-insulated circuit interrupters in the housing. The apparatus also includes a first bus assembly in the housing and coupled to the first plurality of gas-insulated circuit interrupters, and a second bus assembly in the housing and coupled to the second plurality of gas-insulated circuit interrupters. The apparatus further includes at least one connector configured to interconnect the first bus assembly and the second bus assembly.

An electrical connector includes a tubular housing having a partition wall extending in a direction perpendicular to a longitudinal direction of the tubular housing and a bus bar embedded in the partition wall of the housing in a state of penetrating the partition wall in the longitudinal direction. The partition wall is located at a substantially center in the longitudinal direction. A through hole is formed at a position of the bus bar at which the bus bar is embedded in the partition wall. A part of the partition wall is filled in the through hole. A range of the partition wall away from the position at which the bus bar is embedded in the partition wall has a thinned part.

A first opposing surface inclination angle of a protruding first solid insulating material of a first high-voltage device is smaller than a second opposing surface inclination angle of a dented second solid insulating material of a second high-voltage device. A hollow truncated-cone flexible insulating material of which the thickness before insertion between the first high-voltage device and the second high-voltage device is the same at every part and the elasticity modulus gradually increases from a small-diameter side toward a large-diameter side, or a hollow truncated-cone flexible insulating material of which the thickness before insertion gradually increases from a small-diameter side toward a large-diameter side and the elasticity modulus is the same at every part, is compressed and sandwiched between the first solid insulating material and the second solid insulating material.

A switchgear enclosure is provided. The switchgear enclosure includes a plurality of switchgear panels and a plurality of ducts extending through the switchgear panels. Each switchgear panel includes an exterior housing, a busbar compartment defined within the exterior housing, and an exhaust system. The busbar compartment surrounds a busbar extending through the switchgear panel. The exhaust system includes a vent path structure configured within the exterior housing to at least partially surround the busbar compartment, a first channel defined between the vent path structure and the exterior housing, and a first vent opening formed on the vent path structure. The first vent opening directs arc gases within said busbar compartment to the first channel. The ducts are in fluid communication with the first channels of the switchgear panels to distribute arc gases between the first channels.

An insulating system includes an electrically insulating, substantially disk-shaped insulating configuration which spans a base surface. The insulation configuration includes at least one first and one second sub-element. A joining gap is disposed between the two sub-elements. An assembly method for an insulating system is also provided.

A method, apparatus, and system are described for a radial bus Shared Resource Distributed electrical power Distribution System, which has multiple electrical power distribution platforms and a radial power distribution bus. The multiple electrical power distribution platforms are coupled to the radial bus in an interlaced fashion to supply AC electrical power to the downstream electrical loads. The electrical loads are dual corded and are configured to nominally receive AC electrical power from two separate power distribution platforms. A first power distribution platform electrically connects to a first set of the dual corded electrical loads. Also, the first power distribution platform electrically connects to a second set of the dual corded electrical loads. A second power distribution platform electrically connects to the first set of the dual corded electrical loads, and the second power distribution platform electrically connects to a third set of the dual corded electrical loads.

An auxiliary compartment for housing at least one electrical device is associated with an auxiliary cubicle of a switchgear enclosure. The auxiliary compartment is removably mounted in the corresponding auxiliary cubicle for quick disconnection of the electrical device from an associated circuit breaker in an adjacent circuit breaker cubicle. The auxiliary compartment includes a first connection connected to the electrical device. The auxiliary cubicle includes a second connector attached to the auxiliary compartment rear wall that is removably engageable with the first connector. The second connector is connected with the circuit breaker in the adjacent circuit breaker cubicle. The electrical device in the auxiliary compartment can be quickly disconnected from the power and communication connections with the circuit breaker in the adjacent circuit breaker cubicle by withdrawing the auxiliary compartment from the auxiliary cubicle to disconnect the first and second connectors.
