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:
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:
The breaker has a main contact point, an arc rupture contact point, and mobile contact and stationary contact arrangements. The mobile contacting unit has a contact cylinder that is connected to a contact support. A blowing cylinder (29) is provided at the contact cylinder and includes an opening, whose inner diameter is equal to an outer diameter of a section of a contact pin such that the contact unit is separated from the contact pin section. An insulating plastic material of the blowing cylinder is made of gas releasing material.
