Air insulated switchgear with operating device for effect circuit breaker

Abstract

With the intention of simplifying the replacement of an operating device (4) of an air insulated switchgear (1) having a power circuit breaker (3), the operating device has been made dockable. By dockable is meant that the operating device can be readily removed from and replaced on the circuit breaker, i.e. can be separated from and connected to the circuit breaker without needing to influence the function thereof. This has been made possible by providing the operating device with guide parts, such as a splined, rotatable outward shaft, and by providing the switchgear with guide parts which correspond to and receive the guide parts on said shaft, for instance a splined hole provided in a shaft for operating the circuit breaker and receiving and cooperating with the splined shaft. In modern switchgear, the operating device is damaged more often than the circuit breaker, and a dockable operating device enables the device to be removed readily without affecting the circuit breaker function.
