Technical Field

[0001] This utility model specifically relates to the field of handheld partial discharge detectors, and more specifically to a handheld partial discharge detector that is easy to use outdoors. Background Technology

[0002] In the operation and maintenance of power systems, partial discharge detection is crucial for assessing the insulation condition of electrical equipment. As power infrastructure continues to expand to wider areas, including remote mountainous regions, field substations, and urban outdoor power grids, the demand for on-site, rapid, and accurate partial discharge detection of electrical equipment is increasing.

[0003] Traditional partial discharge detection instruments are mostly large benchtop devices or bulky portable instruments, which presents several inconveniences. First, in complex outdoor environments, their size and weight limit the portability for inspectors, especially when long-distance hiking inspections or operations in mountainous areas with poor transportation; moving these devices becomes a heavy burden. Second, the outdoor environment is highly variable, and traditional instruments have limited protective capabilities, making them unsuitable for harsh weather conditions such as sandstorms, rain, extreme temperatures, and high humidity, easily leading to instrument malfunctions or decreased detection accuracy due to environmental factors. Third, the complexity of operation is also a problem. Many traditional detectors have numerous parameter settings and lengthy operating procedures, requiring inspectors to possess high levels of professional skills and extensive experience, which often fails to meet the rapid response requirements of emergency outdoor detection tasks.
