摘要： A gas-insulated switchgear includes a tank filled with an electrically insulating gas, first and second conductors disposed within the tank, a disconnector for disconnecting the first conductor and the second conductor from each other, and a grounding switch for grounding the first conductor when the disconnector is in an open position. The disconnector includes a first and second fixed electrode disposed on the first and second conductors, respectively, a bridging movable electrode that is always maintained in contact with the first electrode and that is slidably movable for contacting with and separating from the second fixed electrode to connect and disconnect the first and second fixed electrodes, and an operating mechanism for opening and closing operation of the movable electrode. The grounding switch includes the bridging movable electrode which is in contact with the first contact, and a third fixed grounding electrode disposed to the tank capable of contacting with the movable electrode when the movable electrode is separated from the second electrode. The operating mechanism is provided with an electrically insulating operating rod extending through the first fixed electrode in the direction of movement of the movable electrode.

摘要： In an isolating switch for metal-clad, compressed-gas insulated high-voltage switchgear, a mechanical control unit containing a rotatably supported lever arrangement. The lever arrangement locks automatically in a neutral position and retains an auxiliary contact pin until it is released by a guide surface connected to the main contact pin. A mating contact of the auxiliary contact pin is also spring-loaded and follows this auxiliary contact pin somewhat after being released, initially while maintaining the equipotential bonding.

摘要： A disconnecting switch has two switches, wherein a first switch comprising a sliding arc contact, which is spring biased, is connected with a resistor in series, and a second switch comprising a main state contact is connected with the first switch with the resistor in parallel. A movable contact is driven so as to contact both the sliding arc contact over a given distance and the main static contact at a given position of the given distance. When the disconnecting switch is interrupted, the second switch is opened first and then the first switch is opened. Current limiting action due to the resistor enables easy interruption of the disconnecting switch.

摘要： A switching assembly for a high voltage switching installation includes a tubular movable main switching contact in which is disposed an auxiliary switching pin. An elastic spring drive with a drive lever and a cocking lever is pivotably attached at an outer part of a shaft traversing the movable main switching contact. The drive lever is connected at an end opposite the pivot shaft to one end of a coupling lever in turn pivotably connected at an end to the auxiliary switching pin by means of a shaft. A hinged spring is connected at one end to the drive lever and at an opposite end to the cocking lever. A guide roller of a mechanical control is rotatably secured to the cocking lever and is disposed in a longitudinal guide slot for controlling the cocking of the spring to shift the drive lever between two end positions.
