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 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.
Abstract:
Instalación de conmutación con al menos dos campos (11, 12), al menos uno de los cuales presenta un conmutador de separación de la carga (73, 74, 75), en la que cada campo (11, 12) presenta al menos una pared frontal (14), una pared trasera, una pared de fondo y una pared de cubierta (15) y una alimentación de cables y barras colectoras de corriente, que cruzan al menos un campo (11, 12), caracterizada porque cada campo (11, 12) está configurado modular y forma un primer módulo (11, 12), y porque entre la pared frontal (14) y la pared trasera de cada módulo está fijado, respectivamente, un elemento de soporte (32), en el que se puede fijar, respectivamente, un conmutador de separación de la carga (73, 74, 75), de manera que su pieza de contacto móvil es móvil verticalmente y el conmutador de separación de la carga está conectado en el extremo superior con las barras colectoras de corriente y las soporta, en la que el elemento de soporte (32) está conectada fijamente con la pared frontal y/o la pared trasera.
Abstract:
A switching device (102, 104, 106) for electric power distribution, electrically connectable to an electrical conductor (114, 116, 118), the switching device comprising a breaker (126, 128, 130) electrically connectable to the electrical conductor, and an at least partially electrically conductive housing (120, 122, 124) to which the breaker is mounted, the housing having an outer surface (134).The breaker comprises at least one electrically conductive first contact (202) and one electrically conductive second contact (204), the second contact being movable and in relation to the first contact and in relation to the housing, and when the first and second contacts are in contact the breaker is in a closed position, and when the first and second contacts are separated the breaker is in an open position. The switching device is arranged to provide a current path between the breaker and the electrical conductor, and the housing houses at least one guiding member (150, 152) for operating the second contact (204), the at least one guiding member being movable in relation to the housing, wherein the at least one guiding member comprises a biasing assembly (151) arranged to bias the second contact against the first contact when the breaker is in the closed position. The biasing assembly comprises a plurality of biasing members (156, 158) comprising a first biasing member (156) and a second biasing member (158). A switchgear for electric power distribution comprising at least one such switching device.
