[0002] Composite jacket arrester is a device used to protect power transmission line equipment from lightning strikes. It is usually composed of metallic components and insulating parts, which can effectively disperse lightning energy, reduce damage to equipment caused by lightning strikes, and promote the reliability and safety of power transmission systems. After the composite jacket arrester is produced, it is necessary to conduct explosion-proof tests on the composite jacket arrester for some special use scenarios. The existing explosion-proof test equipment can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0003] The explosion-proof test equipment widely used on the market needs to perform high-voltage impact on the composite jacket arrester when in use. Once the surface of the composite jacket arrester is broken, some flying fragments are likely to be generated, which poses certain safety hazards and increases the difficulty of cleaning the test bench. For this reason, we propose an explosion-proof test equipment for composite jacket arrester to solve the above problems. Utility Model Content
