Abstract:
The invention relates to a load disconnecting circuit with a housing that has a first housing section, which houses the drive, and has a second housing section, which houses a fixed contact element and a longitudinally extended moving contact element. The second housing section has a longitudinal extension adapted to the moving contact element. Field-control rings are placed on the second housing section while encircling it, of which the first are arranged in the vicinity of the fixed contact element and the second are arranged in the vicinity of the switch-off position of the moving contact element. Via a respective connection conductor, the first field-control ring is connected to the potential of the fixed contact element, and the second field-control ring is connected to the potential of the moving contact element when in its switch-off position.
Abstract:
The invention relates to a switchgear comprising at least two panels, at least one of which is provided with a switch-disconnector. Each panel encompasses at least one front wall, a rear wall, a bottom wall, a top wall, a wire feed, and busbars which embrace at least one panel. Each panel is configured in a modular fashion and forms a first module. One respective support element to which one respective switch-disconnector can be fixed is fastened between the front wall and the rear wall of each module, said support element being connected in a fixed manner to the front wall and/or the rear wall. The switch-disconnectors and the support element of both modules are located on the same level and are configured in an identical manner.
Abstract:
The invention relates to a fuse system for a switchgear assembly, especially for a medium voltage switchgear assembly. The fuse system comprises a plurality of fuses which correspond to the number of phases, every fuse having a tripping bar that projects from the face of the fuse under the effect of the force of a spring when the fuse comes into action. A sealing body, with a spring arrangement interposed, pushes a sealing head into the interior of a receptacle receiving the fuse. A two-armed lever is received on the sealing head, one arm covering a tripping mechanism which actuates a power switch.
Abstract:
The system has load isolation switches, earth switches and similar and a number of cable accesses (13) in the lower region of the switching system corresponding to the number of phases, with which earth switches can be brought into contact with earth blades (20). The earth blades are behind a shielding plate (22) in the off state. The shielding plate has a number of slots corresponding to the number of earth blades through which the earth blades can be pivoted into the earthing position.
Abstract:
The switchgear has two cable panels (11, 12), in which one panel includes a circuit breaker, and each panel includes a front wall, rear wall, a bottom wall, a top wall, a cable guidance and busbars. The cable panels are designed to form a module, and a fuse panel (13) is designed to form another module. A support unit is attached between the front and rear walls of each module, and the walls of each module are interconnected by welding.
