In order to develop a gas-insulated medium-voltage switchgear assembly, which has an encapsulated container for accommodating components of the medium-voltage switchgear assembly, a grounding contact and a grounding busbar terminal provided on the outer side of the container, such that it has a simple and economical design, it is proposed that the grounding contact is secured by integral bonding in a container opening and has the grounding busbar connection terminal.

A multipurpose relocatable structure includes a floor system, a framework secured to the floor system, and walls coupled to the framework. The walls include a number of panels that are secured along adjacent vertical edges. The multipurpose relocatable structure may include a preconfigured interior, one or more doors having an emergency escape hatch, a protected electrical connector, an environmental control system that is configurable between operational and transport configurations, and lifting corners having securement apertures.

The present disclosure provides a coupling system for coupling a medical accessory to an accessory support is provided. The present disclosure also provides a system for powering a medical accessory with an accessory support.

Circuit breakers with a housing with a line side and a load side and an electronically controlled lock-out lock member coupled to the housing configured to electronically controllably travel between a first position and a second position. In the second position, the lock member is in a lock-out position and prevents the handle from moving to an ON position associated with electrical current conduction and in the first position the lock member is translated to a position that allows the handle to move to the ON position.

A modular high voltage supply system has a mobile adapter transformer with a high-voltage output side and a low-voltage input side, electrical connecting input-terminals being foreseen at the mobile adapter transformer outer surface, a mobile container with a low voltage supply system, mounted stationarily therein, having a high current busbar and at least one electrical frequency converter connected thereto, electrical connecting output-terminals for the high current busbar being foreseen at an accessible the mobile container edge; and a modular interim busbar system, for temporary electrical connection of input- and output-terminals, having at least one interim busbar with at least one elongated busbar basic module mounted on a frame structure and respective resilient electrical connections on both busbar basic module ends forming an electrical connection to the input- and/or output-terminals and arranged such that a transmission of vibrations from the mobile adapter transformer to the mobile container is suppressed.

An electric power distributor comprises a distributor housing, conversion parts which convert electric current from outside of the distributor housing to low-voltage alternating current, a transformer which transforms the low-voltage alternating current from the conversion parts to high-voltage alternating current and a power transmission part which transmits the high-voltage alternating current from the transformer to the outward distributor housing. The distributor housing comprises two conversion parts—and the power transmission part—inside. The transformer is attached to the distributor housing from outside. The transformer and the power transmission part are placed along a predetermined direction in this order, the two conversion parts are placed along a direction approximately orthogonal to the predetermined direction at an opposite side to the transformer with regards to the power transmission part.
