[0002] Lightning arresters are commonly used for overvoltage protection in power systems. They can protect electrical equipment in power systems from damage caused by lightning overvoltage and operating overvoltage. Some types of lightning arresters include insulating jackets. In order to ensure creepage distance requirements and reduce the contaminated area of ​​the insulating jacket, multiple insulating rings are often arranged at intervals on the insulating jacket. After this type of lightning arrester is manufactured, it needs to be packaged in a box before transportation or storage.

[0003] In the prior art, the protective box for the lightning arrester often uses plastic foam to support and fix the lightning arrester. The use of plastic foam is not only troublesome to operate, but also uses more plastic foam to cause greater pollution to the environment, and the use effect is not good. Utility Model Content

[0007] The locking mechanism also includes a connecting piece and a fastening bolt. The connecting piece is fixed to the bottom of one end of the locking frame. A through hole matching the connecting piece is opened at one end of the support frame, and the bottom of the fastening bolt passes through the connecting piece and the through hole.

[0008] By adopting the above technical solution, by placing the lightning arrester inside the support frame of the first box body, the staff clamps and fixes the lightning arrester through two or more locking mechanisms, clamps the locking frame between the two groups of insulating rings of the lightning arrester, fits the connecting piece with the top of the through hole, and then fixes the locking frame with the fastening bolts. Since each group of locking frames is elastically connected with side support plates on both sides, under the action of the spring, the two groups of side support plates can be squeezed and positioned on the inner sides of the two groups of insulating rings, thereby further improving the stability of the placement of the lightning arrester, greatly improving the overall safety of the lightning arrester, and effectively reducing the problem of environmental impact caused by the use of plastic foam.

[0009] The utility model is further configured that the locking mechanism also includes a collar, and the collar is fixed to the bottom of one end of the locking frame, and a fixing rod penetrating the collar is fixed to one end inside the first box body.

[0010] By adopting the above technical solution, the locking mechanisms can slide axially along the fixed rod under the action of the ring. That is to say, the staff can make the two sets of locking mechanisms evenly distributed on the outside of the lightning arrester according to the length of the lightning arrester to fix and position it.

[0011] The utility model is further configured such that the top of the first box body is rotatably connected to a second box body matched therewith, and the second box body is rotatably connected to the first box body via a rotating shaft.

[0012] By adopting the above technical solution, the second box body can be closed relative to the first box body, thereby playing a protective role for the lightning arrester.
