摘要（英）：

The invention discloses a device and method for detecting the insulating quality of a high-voltage extruded cable. The device comprises a composite excitation voltage source, wherein the composite excitation voltage source is connected with a high-voltage extruded cable to be tested of which one end is arranged in a first insulating test sleeve through a high-voltage shielding lead, and used for applying voltage signals of different forms to the high-voltage extruded cable to be tested; the other end of the high-voltage extruded cable to be tested is arranged in a second insulating test sleeve; a cable metal sheath at one end is grounded through a metal sheath grounding lead; a cable metal sheath at the other end is provided with a metal electrode on the surface, connected with the input end of an oscilloscope through a radio frequency signal coaxial cable, and used as a detection antenna for an electromagnetic wave signal transmitted in the high-voltage extruded cable to be tested; and the oscilloscope is used for acquiring the electromagnetic wave signal in order to determine the insulating quality of the high-voltage extruded cable to be tested according to the electromagnetic wave signal. The method for detecting the insulating quality by using the device is more comprehensive, and improves the detection efficiency.
