Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage cabinet detection devices, in particular to a local discharge detection device for a high-voltage cabinet. Background Art

[0002] High-voltage switchgear refers to the switchgear used for power generation, transmission, distribution, power conversion and consumption in the power system. It plays the role of switching, controlling or protecting. When there are insulation defects inside the high-voltage switchgear, partial discharge will occur. Detecting partial discharge through the discharge detection device can effectively determine the insulation state of the switchgear equipment. Effective detection of partial discharge is of great significance to ensure the safe and stable operation of the switchgear.

The utility model can facilitate the user to limit and fix the discharge detector body and the ultrasonic probe during detection, thereby avoiding direct contact between the user and the high-voltage switch cabinet and reducing the occurrence of electric shock. At the same time, the ultrasonic probe can be guided and moved, which is convenient for the user to detect different areas of the high-voltage switch cabinet and improve safety and convenience.

[0004] Although the above-mentioned existing partial discharge detection device can perform discharge detection inside the high-voltage cabinet, the above-mentioned high-voltage cabinet partial discharge detection device adopts manual adjustment of the detection position, which is cumbersome and inconvenient to operate manually, and cannot detect the discharge state inside the high-voltage cabinet in real time. Moreover, during detection, it is located at the front of the cabinet, which affects the inspection and disassembly of the electrical components of the discharge part; therefore, it does not meet the existing needs. In this regard, we propose a high-voltage cabinet partial discharge detection device. Utility Model Content
