The invention discloses high voltage cable partial discharge monitoring equipment as well as a system thereof, comprising a shell and mounting plates. The high voltage cable partial discharge monitoring equipment is provided with a compression device, and a second threaded rod is rotated for changing space between the mounting plates at the two sides, so that a roller can firmly fix a high voltagecable, and the high voltage cable can be fixed more firmly under the action of a first spring; a transmission device is arranged, and a motor drives a first gear and first bevel gears to rotate, so that the first bevel gears at the two sides are respectively meshed with second bevel gears and rotate; by virtue of rotation of a telescopic rod, a third bevel gear is meshed with a fourth bevel gearand rotates, and the roller is driven to rotate by virtue of the fourth bevel gear, so that the high voltage cable partial discharge monitoring equipment can automatically move forward on a high voltage cable, efficiency is greatly improved, and operation is simple and efficient; and by arranging a rubber mat, the roller is effectively avoided from destroying the outer surface of the high voltagecable. The high voltage cable partial discharge monitoring equipment disclosed by the invention is simple in structure and has the advantages of easy operation and good universality.
Description
technical field [0001] The invention relates to the technical field of high-voltage cable partial discharge monitoring, in particular to high-voltage cable partial discharge monitoring equipment and a system thereof. Background technique [0002] Cable partial discharge refers to the discharge that occurs between the electrodes but does not penetrate the electrodes. These weak discharges have a cumulative effect, which will gradually deteriorate the dielectric properties of the insulation, enlarge the defects, and finally lead to the breakdown of the entire insulation. In addition, most Mechanical damage can also lead to partial discharges. Cable partial discharge is a monitoring device for measuring partial discharge on cable joints and terminal grounding lines, and realizes the online partial discharge monitoring function of joints, terminals and cables. In the prior art, for high-voltage cable partial discharge monitoring, a high-frequency partial discharge sensor is set...
