[0018] The present invention provides a zinc oxide explosion-proof lightning arrester. It has the following beneficial effects:

[0019] 1. The zinc oxide explosion-proof arrester fixes the position of the arrester body and protects the arrester body by setting a fixing mechanism and a protective mechanism. When installing the arrester or encountering strong winds, the arrester is prone to shaking or changing its angle. Therefore, a fixing mechanism and a protective mechanism are set, an outer frame is set at the center of the arrester, and the outer frame and the arrester body are fixed around to reduce the possibility of shaking of the arrester, and to facilitate the disassembly of the arrester body, which is convenient for subsequent maintenance work to solve the above problems.

[0020] 2. The zinc oxide explosion-proof arrester fixes the arrester body by setting a fixing mechanism. An outer frame is set at the center of the arrester body, and four sets of connecting components are set outside the outer frame, so that the connecting components cooperate with the first connecting plate to complete the fixing of the arrester body, and avoid the shaking of the arrester body in windy weather due to the fixing position not being in the center of the arrester. At the same time, the first clamping ring and the second clamping ring are set in different directions, and the first rubber inner ring and the second rubber inner ring are respectively set inside the first clamping ring and the second clamping ring, which can adapt to different cable directions, and one of them can be selected to fix the cable to reinforce the position of the equipment.

[0021] 3. The zinc oxide explosion-proof arrester is provided with a connection assembly, which is convenient for fixing the position of the arrester body in cooperation with the first connection plate. When fixing the position of the arrester, the bottom thread of the arrester is mostly fixed on the mounting surface, and the top of the arrester is prone to shaking in windy weather. Therefore, when installing or disassembling the arrester body, the outer frame is located at the center of the arrester body, and the position of the sliding plate is controlled to control whether the positioning rod is engaged with the circular groove in the first connection plate, thereby controlling the position of the arrester body.

[0022] 4. The zinc oxide explosion-proof arrester uses two sets of first fixing frames and second fixing frames to protect the arrester body and the shed by setting a protection mechanism, thereby reducing the damage to the arrester body caused by rain or strong winds. A soft board and a fixing tube are set in the first fixing frame, and when the arrester body or the shed is cracked, the broken materials are elastically contacted and stored in the first fixing frame to prevent the broken materials from falling.
