Patent ID: 7310221

Claim:
A switching installation comprising a circuit breaker, which is connected to a cable connection, and optionally a disconnector for making or breaking a conductive connection between the cable connection and a rail system, and an electrically insulating barrier for shielding an element of the switching installation which is under voltage in operation, in which the electrically insulating barrier surrounds at least the parts which are under electric voltage in operation from the circuit breaker to the rail system, including a branch leading to a rail of the rail system, separately for each phase of the switching installation, and also actuating members for the circuit breaker and the optional disconnector, characterized in that the electrically insulating barrier is designed to secure the branch to one of the rails of the rail system in a fixed position, one side of the branch being designed to make breakable contact with an end of the disconnector which is remote from the circuit breaker, and in that the electrically insulating barrier comprises securing means on the inner side for receiving voltage-sealing and/or field-controlling means at the location of the branch, the securing means also being designed to receive insulating support sections for securing the branch in a fixed position and retaining the voltage-sealing and/or field-controlling means.
