Definitions
- the invention relates to a compressed gas-insulated switching device with a grounded encapsulation housing made of electrically conductive material, an electrical phase conductor being arranged in an electrically insulated manner within the encapsulation housing.
- Such a pressure gas-insulated switching device is known, for example, from US Pat. No. 6,459,568 B2.
- the encapsulated housing which is grounded there, surrounds an isolating switch.
- the one connection of the isolating switch device is connected to an interrupter unit of a circuit breaker surrounded by an insulating housing.
- the other connection of the isolating switch device is led through a wall of the encapsulation housing by means of an outdoor bushing. Due to the arrangement of an isolating switching device within an earthed encapsulation housing and an interrupter unit within a housing made of electrically insulating material, a flexible adaptation of the known switching device is hardly possible. ' For example, the interrupter unit of the circuit breaker and the disconnecting device cannot be interchanged easily.
- the object of the invention is to provide a compressed gas-insulated switching device which can be variably equipped with different devices.
- the object is achieved in that the encapsulation housing has a first and a second flange. indicates that a first insulating housing, which surrounds an interrupter unit of a circuit breaker, is connected to the first flange, that a second insulating housing, which surrounds a disconnector, is connected to the second flange via a second coupling housing, that a first connection point the main current path of the interrupter unit is connected to the phase conductor, that a first connection point of the disconnector is connected to the phase conductor, that a second connection point of the main current path of the interrupter unit is led outside from the inside of the first insulating housing and that a second connection point of the disconnector is from the inside of the second insulating housing is guided to the outside.
- a modular construction of the switching device can be carried out. Furthermore, the proven design of guiding an electrical phase conductor within an earthed encapsulation housing can be retained. As a result, switching devices according to the invention can also be used as a replacement for classic dead tank switches.
- coupling housings adaptation to different flange diameters is possible in a simple manner. It is particularly advantageous if the first and the second flange have the same structural design with the same dimensions. This makes it possible to reduce the number of different coupling housings.
- a drive device for moving a movable contact piece of the disconnector is coupled to the first coupling housing. It can also be advantageously provided that a drive device for moving a movable contact piece of the interrupter unit of the circuit breaker is coupled to the second coupling housing.
- the coupling of the drive devices to the respective coupling housings makes it possible to initiate the drive movement in the immediate vicinity of the contact pieces of the circuit breaker or the disconnector to be moved. Elaborate linkages for initiating and deflecting drive movements, for example on the grounded encapsulation housing, are no longer required. This makes it possible to keep the encapsulation housing itself free of drive mechanisms.
- An advantageous further embodiment can provide that the first insulating housing together with the interrupter unit and the first coupling housing and the second insulating housing together with the disconnector and the second coupling housing are interchangeable.
- the interchangeability of the insulating housing makes it possible to construct different circuit variants with one and the same encapsulation housing. In particular, it is possible to adapt the position of the electrical connection points very variably to existing switchgear without having to change the design of the switchgear itself. It when the respective insulating housing and / or the respective coupling housing are of identical design is particularly advantageous. This reduces the number of different housing groups required to manufacture a compressed gas-insulated switchgear.
- the interchangeability means that Towards this end, different disconnectors and circuit breakers with different technical characteristics can be combined on one switchgear.
- one wall of the coupling housing is penetrated by a drive shaft.
- the drive shafts can have different dimensions or also have different positions on one of the coupling housings.
- the drive shafts By arranging the drive shaft on the coupling housing, only changes to the coupling housing itself are therefore necessary for various drives. Since no interventions in the insulating housing are necessary, similar insulating housings can be used.
- the drive devices are arranged on the outer circumference of the respective coupling housing and are carried by the respective encapsulation housing.
- the shapes of the different drive devices can also differ from one another.
- the mounting location of the respective drive devices on the coupling housing can also differ. Adjustments for different positions of the drive devices are only to be made on the coupling housings themselves.
- the insulating housing or the encapsulation housing itself remains largely unaffected by such adaptation designs. This further supports the modularity of the overall construction.
- an embodiment of the invention is shown schematically in a drawing and described in more detail below.
