Abstract: A bus bar connection which electrically interconnects switchboard sections by at least one electrical connection element, the bus bar connection including bellows which can be mounted between the switchboard sections, can be filled with insulting gas, and surround the electrical coupling element of the bus bar connection in a gas-tight manner.

Abstract: A connecting sleeve generally used for a bus bar connection is produced from an insulating elastic material, often an elastomer material, having insulating properties which are deteriorated by partial discharges and decrease over the operating time of the switchboard system. According to the invention, so-called partial discharge measuring methods must be carried out, inter alia also in the UHF range (UHF: ultra high frequency), in order to identify damaging effects on the insulating material in time. For the reliable and simple detection of the measuring signals, the connecting sleeve (M) has an outer, electroconductive surface (OA) which is earthed, and an inner, electroconductive surface (OI) to which the voltage potential of the bus bar (S) is applied, in addition to a coupling electrode (KE) which is integrated into the insulating material (I).

Abstract: According to the invention, a bus bar connection (SSK) is used which electrically interconnects the switchboard sections (F1, F2,) by means of at least one electrical connection element (KS), said bus bar connection (SSK) comprising bellows (FB) which can be mounted between the switchboard sections (F1, F2,), can be filled with insulting gas, and surround the electrical coupling element (KS) of the bus bar connection (SSK) in a gas-tight manner. Said measures enable a very flexible contact connection between the switchboard sections (F1, F2,), which not only offers a higher degree of tolerance when interconnecting the parts to form a switchboard system, but is also resistant to movements of the switchboard sections (F1, F2,) in terms of the gastightness.

Abstract: The system for interconnecting pairs of aligned axial conductors of cells housed in enclosures (3, 3′) equipped with bushings (1, 1′) is made up of modules each consisting of an interconnection device (8) and an electrical insulation structure positioned around the interconnection device. The electrical insulation structure is a flexible insulative sleeve (12) of elastically adaptable length whose flat annular ends are pressed by removable clamps (13, 13′) against the bushings (1, 1′) through which the conductors of the connection device pass.

Abstract: The current feedthrough is more particularly intended to provide connection to a bare conductor of a piece of gear housed inside metal cladding including a wall provided with an opening designed to put a conductive element of the gear into connection with one end of a conductive element housed axially inside the feedthrough. It includes a metal link and screen piece of cylindrical appearance that is held coaxially about the conductive element by a body of molded insulating material covering it in part and forming a plug that is impermeable to gas. The link and screen piece is terminated by a cylindrical portion projecting from the body, with the piece being welded to the periphery of the opening via the end of its cylindrical portion.

Abstract: The module comprises a metal enclosure constituting a metal-clad housing receiving a multipole circuit-breaker and disconnector units where disconnection is performed by tilting the set of poles away from an in-service position in which each pole is simultaneously connected to two current feedthroughs projecting through the top wall of the housing. The distribution substation comprises a metal enclosure constituting a metal-clad housing that is subdivided into compartments serving specifically to house three multipole circuit-breaker and disconnector units in parallel alignment between two feeders. The poles of the units are interconnected via current feedthroughs passing through intermediate compartments, each of which has a feeder terminating therein.

Abstract: A substation of the "one-and-one-half breaker" type has three identical gastight cubicles in the form of a rectangular parallelepipeds (11, 11', 11") each containing one circuit breaker and two disconnects, and each having electricity lead-ins for connecting the disconnectors with external busbars and/or cables. The lead-ins are disposed in oblique rows through the top face of each cubicle in a front row of lead-ins (27, 27A, 27B) and in a parallel rear row of lead-ins (27', 27'A, 27'B). The two outermost cubicles (11, 11") have lead-ins, front lead-ins in one case and rear lead-ins in the other, fitted for connection to a respective incoming feeder. The middle cubicle (11') has the lead-ins of the one row individually connected by interconnections busbars (35) to the lead-ins constituting a row of the one of the adjacent cubicles that is not fitted for connection to an incoming feeder.
