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: A switch-gear or control-gear system for medium or high voltage use includes an external housing containing the switch-gear or control-gear system, which is configured for unmanned operation and maintenance. The switch-gear or control-gear system is configured for unmanned operation and maintenance with a robotic system or manipulator and the robotic system or manipulator is provided with a camera system and an image recognition system. The robotic system is provided with a data network or an external data communication interface.

Abstract: A switchgear or controlgear with unmanned operation and maintenance includes: an equipment safety system that includes a steering and control system for calculating a action radius of a robot system. An acting area in an internal space of the switchgear or controlgear is divided into virtual zones. Each action in each virtual zone is precalculated predictively as a micro simulation in which actual sensor data are considered before an intended action is triggered.

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 substation for medium or high voltage includes: switchgear or controlgear with unmanned operation and maintenance; an inner room in which the switchgear or controlgear are located, the inner room being hermetically enclosed by an outer housing, the inner room being locked against the outer housing by an inner, automatically operated door; and a robot system, the robot system being implemented such that an acting area of the robot system is extended from the inner room, partly in an area outside the inner room, but inside the outer housing, where spare parts are stored in a spare parts hand over area, for maintenance.

Abstract: A switch-gear or control-gear system, in particular a low voltage switch-gear or control-gear system is configured for unmanned operation and maintenance. The switch-gear or control-gear system is configured for unmanned operation and maintenance with a robotic system or manipulator and wherein the robotic system or manipulator comprises a camera system and an image recognition system.

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.
