Embodiment Construction
[0037] Such as figure 1 As shown, a new type solid insulation vacuum switch three-position isolation grounding switch module, including three-position isolation grounding switch operating terminal 1, three-position isolation grounding switch 3, bus interface 11, outlet terminal 13, vacuum switch 16, ring Oxygen resin housing 18 and end cap 20. The three-position isolating grounding switch 2 and the vacuum switch 16 are arranged horizontally in the same air chamber, and are connected to the conductive contact finger seat 15 through the movable contact support 6, and the conductive contact finger seat 15 is installed on the movable contact through a detachable fixed connection. Support 6 on. The detachable fixed connection between the conductive contact finger seat and the movable contact support may be threaded connection, pin connection, elastic deformation connection, lock connection, or plug-in connection.
[0038] In this embodiment, it is selected that the conductive con...
