For example, the prior art Chinese patent announcement number "CN218213268U" discloses an online cable partial discharge monitoring system, which belongs to the field of partial discharge monitoring technology. It includes a base plate, two vertical boxes are fixed on the top of the base plate, a round tube is rotatably penetrated on the vertical box, a rotating device for driving the round tube to rotate is arranged in the vertical box, pillars are fixed on the top of the opposite ends of the two round tubes, a track plate is fixed between the two pillars, a slider is slidably installed on the track plate, a UHF partial discharge sensor is installed on the slider, and a placement plate is fixed between the two vertical boxes; the utility model realizes that the UHF partial discharge sensor makes a circular motion around the cable, performs surrounding monitoring around the cable, realizes all-round partial discharge monitoring of the cable, and the monitoring is comprehensive, the monitoring accuracy is improved, the cable partial discharge situation can be monitored over a long distance, and the monitoring range is wide.

[0004] Some cable partial discharge monitoring devices perform partial discharge monitoring through detectors and sensors. However, in actual operation, considering that the dust on the periphery of the cable will cause the insulation strength of the cable surface to decrease, the dust will affect the partial discharge monitoring data of the cable when the sensor is monitoring. Similar monitoring devices do not have the function of cleaning dust. In this way, the data obtained by directly monitoring the cable will lead to a decrease in accuracy. Utility Model Content

[0005] The utility model aims to solve the above-mentioned shortcoming of the prior art that the dust cleaning function is not provided, and proposes a bracket type cable partial discharge monitoring device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
