Switching device and related switchgear

摘要

An exemplary switching device connects and disconnects a power line to and from, respectively, at least an associated electrical load. The switching device includes at least one phase of the switching device having a housing that includes a movable contact configured to be coupled to and separated from a corresponding fixed contact, wherein the at least one phase of the switching device includes an electrically semiconducting assembly having an insulating support operatively associated with a plurality of semiconductor devices, wherein the plurality of semiconductor devices are connected in series and are electrically connected to said fixed contact and to said movable contact, and wherein the semiconducting assembly is configured to be installed into the housing to surround at least a portion of at least one of said fixed contact the movable contact when it is coupled to the fixed contact.

1. A switching device for connecting and disconnecting a power line to and from, respectively, at least an associated electrical load, comprising:
at least one phase of the switching device having a housing that includes a movable contact configured to be coupled to and separated from a corresponding fixed contact, wherein the at least one phase of the switching device comprises: an electrically semiconducting assembly having an insulating support operatively associated with a plurality of semiconductor devices, wherein said plurality of semiconductor devices are connected in series and are electrically connected to said fixed contact and to said movable contact during a portion of the movement of said movable contact, and wherein said semiconducting assembly is configured to be installed into said housing to surround at least a portion of at least one of said fixed contact and said movable contact when it is coupled to the fixed contact, wherein said semiconducting assembly comprises first connection means electrically connecting said plurality of semiconductor devices to the fixed contact, and second connection means for electrically connecting said plurality of semiconductor devices to the movable contact, wherein said movable contact is movable to:
a first position, where it is coupled to the fixed contact;a second position, where it is spatially separated from the fixed contact and electrically connected to the second connection means; anda third position, where it is spatially separated from the fixed contact and electrically disconnected from the second connection means, and wherein said movable contact moves along an axial direction to said first, second and third positions, and said semiconducting assembly comprises:
a hole suitable for receiving the fixed contact and extending along said axial direction (X) to allow passage therethrough of the movable contact to couple to and separate from the fixed contact.
