Description

Technical Field

[0001] The utility model relates to the technical field of partial discharge detection, in particular to a partial discharge detection device for electric power equipment. Background Art

[0002] During the operation of power equipment, partial discharge is an incomplete discharge across electrodes. Usually, the degree of partial discharge is very small. However, this continuous accumulation process will eventually lead to damage to the insulation layer. Its impact is not only causing power outages but also endangering personnel safety. Therefore, it is necessary to detect partial discharge of power equipment.

[0003] Authorization announcement number CN218441733U discloses a partial discharge detection device for electric power equipment. This patented technology provides a power mechanism and a fixing mechanism. The power mechanism can drive the fixing mechanism to move under the action of a connecting rod. As the fixing mechanism moves in opposite directions, the fixing purpose is achieved, so that the partial discharge detection device body is stably fixed in the required location. Compared with the traditional fixation using bolts, this improves the installation efficiency and facilitates subsequent maintenance. However, in this solution, when testing the electric power equipment, the movement of the threaded barrel is adopted. Under the action of the connecting rod, the moving rod can be moved, and then the clamping plate is driven to move, thereby achieving the purpose of fixing the electric power equipment. This method not only requires manpower to rotate the threaded barrel, which is time-consuming and labor-intensive, reducing the detection efficiency, but also the manual clamping operation cannot accurately control the force. Too little force will result in unstable clamping, while too much force will easily cause damage to the electric power equipment. Therefore, a partial discharge detection device for electric power equipment is needed to improve the above-mentioned problems. Utility Model Content
