APPARATUS FOR GENERATING SIMULATED PARTIAL DISCHARGE SIGNAL

摘要

The present invention relates to a device for generating a simulated partial discharge signal. The device includes: a discharge generation electrode (30) which is placed inside a chamber (10), is arranged at both sides of an insulator (20) in which a junction surface (25) is formed by two insulating materials (21, 23) being overlapped with each other, and receives a voltage to generate partial discharge; a high voltage application unit (35) and a grounding unit (38) which are connected to the discharge generation electrode (30) and apply a voltage to the discharge generation electrode (30); an interface pressure control unit (40) which pressurizes the two insulating materials (21, 23) to control the pressure of the junction surface (45) between the two insulating materials (21, 23); and a gas pressure control unit (50) which controls gas pressure inside the chamber (10). The present invention generates partial discharge by simulating a junction interface structure between actual materials of a cable and a junction so that it is easy to acquire and classify a discharge signal of a nondestructive area to prevent failures of an underground cable.
