In terms of power, most forestry faces unique challenges, such as the vastness of the park, harsh weather, and complex terrain, which makes the maintenance of the power grid costly, and the time to restore power after a power outage will be very long. Although the traditional porcelain shell drop-type fuses will initially provide reliable performance, they are difficult to cope with these conditions. Surface pollution in the air will reduce the insulation performance of falling-type fuses, increase the leakage current, and cause unpredictable flashover. These failures require frequent inspections and replacements, and each inspection and replacement requires a large amount of money, which is also the main reason for long-term power outages.
