Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, in particular to a shielding cover of a safety protection type lightning arrester. Background Art

[0002] A lightning arrester is a device used to prevent overvoltage and lightning strikes from damaging electrical equipment. It is usually installed in electrical systems to absorb and release overvoltage or lightning strikes in the electrical system. When the voltage exceeds the normal range, the lightning arrester will quickly conduct and shunt the overvoltage to the ground wire or other safe places to protect the electrical equipment connected to it from damage. When the lightning arrester uses a shielding cover to protect the lightning arrester, the lightning arrester is extended into the shielding cover, but the heights of the lightning arresters are different, and the shielding cover cannot protect lightning arresters of different heights as needed.

[0003] A Chinese patent discloses a shielding cover for lightning arrester testing (authorization announcement number CN204008744U). The top of the cover body of the patented technology is a hollow hemispherical shape, and the lower part of the cover body is a hollow cylinder. The cross-sectional radius of the hollow cylinder is equal to the radius of the hollow hemisphere; a lead-out hole is provided on the hollow cylinder.

[0004] However, there are still some shortcomings in this patent. When the lightning arrester uses a shielding cover to protect the lightning arrester, the lightning arrester is extended into the shielding cover, but the lightning arresters are of different heights, and the shielding cover cannot protect lightning arresters of different heights as needed. Therefore, those skilled in the art provide a shielding cover for a safety protection type lightning arrester to solve the problems raised in the above background technology. Utility Model Content
