Technical Field

[0001] The utility model belongs to the technical field of cable discharge detection, in particular to a cable joint discharge detection device. Background Art

[0002] High-voltage cables are an important part of power equipment, and their reliability is directly related to the safety and stability of the entire power system. When local discharge occurs in high-voltage cables, there will be electric pulses, electromagnetic radiation, ultrasound, ultraviolet light and various chemical products. These discharge information contains rich insulation condition information. By detecting this information, it can be determined whether partial discharge has occurred, and even the location of the partial discharge source can be determined based on the strength of these signals. Ultrasonic waves and ultraviolet light are relatively stable signals, but ultrasonic waves attenuate more seriously with increasing distance, and ultraviolet light has poor penetration. Once blocked, it is difficult to detect.
