Device for simulating high-frequency current propagation of partial discharge of GIL/GIS

A device for simulating high-frequency current propagation of partial discharge of a GIL/GIS, comprising a casing (1), a busbar cavity (14), an adjustable impedor (11), a first metal support (6), a second metal support (8), a third metal support (9), and a high-frequency current sensor (13), wherein:

• the casing (1) is connected to the busbar cavity (14), a conductor (3) is arranged in the busbar cavity (14), and the busbar cavity (14) is provided with multiple air vents (5);
• the first metal support (6) and the second metal support (8) are arranged at a grounding point of the busbar cavity (14) and are separated from each other by an insulating support (7), and the adjustable impedor (11) is connected in series between the first metal support (6) and the second metal support (8) through a wire (12);
• the third metal support (9) has one end connected to the second metal support (8) and another end connected to a grounding grid;
• the high-frequency current sensor (13) is disposed around the wire (12).
