The utility model discloses an intelligent substation process layer interface equipment, including device body and outer joint head, device body below is equipped with the outer joint head, and outerjoint head swing joint is on the device body, and device body below is equipped with the process layer interface, and the welding of process layer interface sets up on the device body. This kind of intelligent substation process layer interface equipment, be equipped with outer joint head and process layer interface, be equipped with the interface inner core, be equipped with the outer union innercore, be equipped with outer union bottom button, outer union bottom button is in outer union kicking block top, it is nested nevertheless unset between outer union bottom button and the outer unionkicking block, connect through threaded rotation between outer joint head and the process layer interface, the outer union kicking block inserts the outer union inner core interface inner core of " concave " type when rotating the connection, compare in cuting straightly the formula interface, the connected mode that this kind of rotation type scarf joint set up is more practical, it is simultaneously more stable, the volume of process layer interface equipment has also been reduced.
