Detachable fracture structure and GIS

The invention relates to the technical field of GIS, in particular to a detachable fracture structure and a GIS. The invention aims to provide a detachable fracture structure and a GIS, the GIS comprises a conductive main circuit, a lightning arrester and a voltage transformer, the lightning arrester and the voltage transformer are horizontally arranged below the main circuit at intervals, and the lightning arrester and the voltage transformer are connected to the main circuit through the detachable fracture structure. The detachable port structure comprises a main circuit connecting conductor, a voltage transformer connecting conductor and a lightning arrester connecting conductor which are connected with one another; and the tail end of the main circuit connecting conductor is provided with a detachable connecting conductor connected with the main circuit. According to the detachable fracture structure, two electrical parts can be directly connected into a main circuit at the same time, the space occupied b
