Abstract: A switch includes a power in contact, a piston, a power out contact, a plurality of flexible locking elements, an earthing contact, and a threaded rod. In a first position, the piston contacts the power in contact and the power out contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the earthing contact and the power out contact. The piston comprises an inner threaded section that engages the threaded rod. Rotation of the threaded rod moves the piston along an axis of the switch between the different switch positions. The piston comprises a groove extending in a direction parallel to the axis. Each of the flexible locking elements is configured such that a part of each of the flexible locking elements moves into and out of the groove as the piston is moved along the axis of the switch.

Abstract: A three-position disconnector switch includes an earthing contact, a power out contact, a power in contact, and a piston. The power out contact comprises first and second parts connected by a leg portion. In a first position, the piston contacts the first part of the power out contact. In a second position, the piston contacts the first part of the power out contact and makes electrical contact with the second part. In a third position, the piston contacts the second part and makes electrical contact with the earthing contact. The piston is configured to move along an axis of the three-position disconnector switch to transition the three-position disconnector switch between the different switch positions.

Abstract: A three-position disconnector switch includes: an earthing contact; a power out contact; a power in contact; a first piston; and a second piston. In a connected switch position the first piston makes an electrical connection with the power out contact and the second piston makes an electrical connection with the power out contact and the power in contact. In a disconnected switch position the first piston makes an electrical connection with the power out contact and the second piston makes an electrical connection with the power out contact. In an earthed switch position the first piston makes an electrical connection with the earthing contact and with the power out contact and the second piston makes an electrical connection with the power out contact.

Abstract: A switchgear or control gear includes: at least one first compartment; at least one second compartment; a plurality of main switchgear or control gear components including a main busbar system, a three position linear or rotational movement disconnector, a circuit breaker, and at least a first part of an insulated cable connection; and a plurality of auxiliary switchgear or control gear components including a disconnector drive and a circuit breaker drive. The plurality of main switchgear or control gear components are housed in the at least one first compartment. The plurality of auxiliary switchgear or control gear components are housed in the at least one second compartment. When one or more of the plurality of main switchgear or control gear components is energized, the at least one first compartment is hermetically sealable or maintainable at an internal air pressure greater than ambient air pressure.
