- connection of a busbar 14 to the associated circuit breaker 12 is carried out either directly, as shown in FIG. 1 for the set of bars 14 located in the foreground, or by means of a connection sleeve 54, as it is shown in Figure 2 for example.
- the circuit breaker 12 mainly comprises an outer tank 28 hermetically closed and filled with a dielectric gas, and an interrupting chamber 30 disposed inside the tank 28.
- a drive mechanism 32 of the interrupting chamber 30 is connected to the circuit breaker 12, at one end of the tank 28.
- the tank 28 and the breaking chamber 30 of the circuit breaker 12 are elongated and generally coaxial, the circuit breaker 12 is therefore installed horizontally in the installation 10.
- a support structure 34 is arranged under the circuit breaker 12 to support it and ensure the ground connection of the circuit breaker 12 and other electrical equipment.
- the other electrical devices each comprise an outer enclosure 36 in which an electrical component 38 is arranged.
- the electrical components 38 of the other electrical equipment and the circuit breaker 12 are electrically connected to one another by means of connecting means 40 which extend through the interior volumes of the enclosures 36 and the tank 28.
- each chamber 36 and the tank 28 comprise at least one opening 42 which is placed in communication with the associated opening 42 of the other enclosure 36 or of the tank 28.
- a flange 44 surrounding each opening 42 allows the fixing of the chamber or the tank 28 to the other chamber 36 or to the tank 28.
- the enclosure 36 of some electrical equipment is filled with a dielectric gas, while other speakers 36 are only filled with ambient air.
- the installation comprises a support member 46, commonly called “cone”, which is located through two openings 42 associated to seal them tightly.
- the support member 46 is made of an electrically insulating material and comprises a central portion of current-conducting material which allows the electrical connection of two electrical components in collaboration with the connection means 40.
- the tank 28 has an opening 42 for connection with the disconnector 22 of the busbar 14 and an opening 42 for connection with the current transformer 16.
- Each opening 42 of the tank 28 is associated with an opening 42 of the enclosure 36 of the disconnector 22 of the busbar 14 and the current transformer 16, respectively.
- a support member 46 is mounted through each opening 42 of the tank 28.
- the internal volume of the tank 28 communicates directly with the interior volume of the associated chamber 36, ie there is no organ of support 46 mounted through the opening 42.
- busbars 14 associated with the different phases of the current line are vertically offset relative to one another. This makes it possible to optimize the space, since each set of bars 14 is oriented mainly horizontally.
- connection of a busbar 14 to the associated circuit breaker 12 is carried out either directly, as shown in FIG. 1 for the set of bars 14 located in the foreground, or by means of a connection sleeve 54, as it is shown in Figure 2 for example.
- connection means 40 comprise an electrical conductor 48 in the form of a connection bar which is situated in the enclosure 36 of the electrical equipment, and whose a first end 50 is connected to the electrical component 38.
- the second end 52 of the connecting bar 48 is connected to the other electrical component, here to the breaking chamber 30 of the circuit breaker 12, either directly or via the support member 46.
- the connecting bar 48 is made such that at least its second end 52 is movable and is able to be disconnected from the breaking chamber 30.
- connection bar 48 is thus movable between a position of connection to the interrupting chamber 30 and a position disconnected from the breaking chamber 30.
- the connecting bar 48 is movable relative to the breaking chamber 30, that is to say here movable in the enclosure 36.
- the displacement of the connecting bar 48 is performed according to its vertical main direction.

- the tank 28 of the circuit breaker 12 can be dismounted from the busbar disconnector 22, as shown in FIG. 4.
- the displacement of the circuit breaker 12 relative to the disconnector 22 of the busbar 14, after disassembly, consists of a displacement of a few tens of millimeters, in order to clear the fastening components. This displacement is greatly reduced compared to an installation according to the state of the art, which requires a downward movement of the circuit breaker of several tens of centimeters.
- the assembly of the circuit breaker 12 with the disconnector 22 of the busbar 14 is performed in a reverse movement, that is to say that the tank 28 of the circuit breaker 12 is assembled to the enclosure 36, then the connection bar 48 is moved so that his second end 52 comes into contact with the fixed contact 56.
- This displacement is achieved by means of the control tool 58.
- connecting bar 48 are further shaped to be able to connect with each other despite the lack of visibility for an operator.
- the fixed contact 56 comprises a conical portion open towards the second end 52 of the connection bar 48.

- the first end 50 of the connecting bar 48 is connected to the electronic component of the busbar disconnector 22 via the conductive portion of the support member 46 and the second end of the connecting bar 48 is fit to come directly in electrical contact with the interrupting chamber 30.
- control tool passes through the busbar disconnector 22, the rod 62 cooperating with the connection bar 48.
- control tool 58 can be mounted on the outside of the tank 28 of the circuit breaker 12 which has an opening dedicated to this application.
- connection means 40 is particularly suitable when it is desired to remove the interrupting chamber 30 from the tank 28. This operation is commonly called a “dewatering” operation and does not require disassembly of the vessel. circuit breaker of other apparatus.
- the invention is not limited to the only connection of the circuit breaker 12 with the disconnector 22 of the busbar 14 and that it can be applied to the connection of the circuit breaker 12 with any other apparatus which is connected to it, such as for example the current transformer 16. Also, the invention can be applied to the connection between two adjacent apparatus.
