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: An apparatus for hot spot sensing where the apparatus includes an input unit, a processing unit,and an output unit. The input unit is configured to provide the processing unit with an image of an object that includes a hot spot. The image data of the image includes image data of the hot spot where the image was acquired by a camera. The processing unit is configured to determine a number of pixels in the image corresponding to a size of the hot spot, an average temperature for the hot spot, the determination comprising utilization of pixel values of the pixels in the image corresponding to the size of the hot spot and the number of pixels in the image corresponding to the size of the hot spot, a surrounding temperature in the image, and a corrected temperature for the hot spot.

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.

Abstract: An indoor switchgear or controlgear arrangement with unmanned operation and maintenance, for use in low, medium, or high voltage, includes: an arrangement of switching devices in an inner housing, which is furthermore provided with an outer housing; and a robot system, acting mainly in the inner housing. At least the switching devices other than maintenance critical parts are withdrawable. The switchgear or controlgear is provided with interlocks in order to prevent a wrong sequence of operation and prevent access to potentially hazardeous compartments. Metallic segregation is provided internally in the inner housing in order to achieve a needed service continuty level.

Abstract: A method for loose joint detection in medium voltage switchgears with busbar joints, circuit breaker upper and lower spouts, and cable connection joints, arranged in an air insulated housing, and medium voltage switchgear itself, in order to create an effective loose joint detection with lower operating expense, but with high performance and accuracy, involves measuring actual temperatures at a first phase as a first temperature (T1), at a second phase as a second temperature (T2), at a third phase as a third temperature (T3), at predefined critical points, such as at the busbar joints, and/or at the circuit breaker upper spouts, and/or at the circuit breaker lower spouts, and/or the cable connection; and comparing temperatures in a logical dependency Ti>(Tj+dT), with i≠j, permuted with i from 1, 2, 3, and j from 1, 2, 3, and setting the alarm if the logical dependency is fulfilled.
