Abstract

A box-shaped lightning arrester includes a mounting plate, a mounting box is fixedly connected with the top of the mounting plate, both sides of the inner wall of the mounting box are fixedly connected with connecting plates, the top and bottom of one side of each connecting plate are movably connected with connecting rods through pins, the other end of each connecting rod is movably connected with an extrusion block through a pin, and a clamping spring is fixedly connected between opposite sides of the two extrusion blocks, the other side of each extrusion block far away from the connecting rods is movably connected with a long rod through a pin, and the other end of each long rod is movably connected with a pushing plate through a pin. The invention relates to the technical field of box-shaped lightning arresters. The box-shaped lightning arrester can be well installed and disassembled, saves time and labor, is very convenient to install and disassemble, is convenient to maintain andreplace, and does not need a plurality of workers, saves manpower, and greatly improves the practicability of the box-shaped lightning arrester.

Description

technical field [0001] The invention relates to the technical field of box-shaped lightning arresters, in particular to a box-shaped lightning arrester. Background technique [0002] The most primitive lightning arrester is a horn-shaped gap, which appeared at the end of the 19th century and was used for overhead transmission lines to prevent lightning strikes from damaging equipment insulation and causing power outages, so it is called "lightning arrester". In the 1920s, aluminum arresters, oxide film arresters and pill arresters appeared. Tube arresters appeared in the 1930s. Silicon carbide arresters appeared in the 1950s. In the 1970s, metal oxide arresters appeared again. Modern high-voltage arresters are not only used to limit the overvoltage caused by lightning in the power system, but also used to limit the overvoltage caused by system operation. The arrester is used to protect electrical equipment from high transient overvoltage hazards and limit the freewheeling...
