[0002] The lightning protection device of electric power tower is an important component to ensure the stable operation of power grid, when lightning occurs, the high-rise electric power tower is easy to become the target of lightning stroke. The lightning arrester is installed at the highest point of the electric power tower, which can attract lightning to discharge first, so that the lightning current is safely guided into the ground through the low-impedance down conductor instead of through the power equipment or line, thereby avoiding the damage of power facilities and power interruption caused by lightning stroke.

[0003] The utility model discloses a lightning arrester for electric power tower, which aims to improve the efficiency and safety of installation and disassembly of the lightning arrester. The lightning arrester is characterized by the connection mode between the installation base plate and the installation base: two sets of locking mechanisms are used to achieve stable locking. When maintenance or replacement is needed, the user only needs to pull the two sets of adjusting levers, which can drive the internal transmission rod to operate, promote the locking tongue to move inward, thereby releasing the restriction of the locking tongue on the locking slot, so that the installation base plate can be quickly and conveniently disassembled. However, this design has certain limitations in actual operation. In particular, when the operator tries to pull the two sets of adjusting levers to release the lock, due to the uneven force transmission, the locking tongue on the side far from the adjusting lever operating end may have difficulty in translation. This situation causes the operator to have to spend extra time and effort to ensure that the locking tongues on both sides can operate smoothly during disassembly, thereby affecting the efficiency of the entire disassembly process. Therefore, it is necessary to improve. UTILITY MODEL CONTENTS
