Abstract

The invention discloses a live-line installation method for a low-voltage detachable lightning arrester. The method comprises the following steps of 1, adjusting the distance between two groups of L-shaped clamping seats according to the length of a lightning arrester body; 2, after the butt joint position of a movable sliding buckle is adjusted, under the condition that an electric box is powered on, fixing a ceramic base into the electric box through bolts; 3, through the butt joint clamping grooves of the L-shaped clamping seats, and utilizing the elastic clamping rods at the two ends of the lightning arrester body toclamp the lightning arrester body between the two groups of L-shaped clamping seats, so that the time required for mounting the detachable lightning arrester is shortened. Meanwhile, the stability of the lightning arrester after mounting can be improved by utilizing the arrangement of the second clamping bolts, and an inclined surface structure at one ends of the butt joint clamping grooves can effectively reduce the resistance of the detachable lightning arrester during quick butt joint, so that the detachable lightning arrester is convenient to mount. The mounting method can be used for quickly dismounting and mounting the low-voltage detachable lightning arrester, and the emergency repair effect of the low-voltage detachable lightning arrester is improved.

Description

technical field [0001] The invention belongs to the technical field of lightning arresters, in particular to a live installation method of a low-voltage detachable lightning arrester. Background technique [0002] The low-voltage detachable arrester combines the working principle of the 10 kV detachable arrester, and the low-voltage arrester can be removed for maintenance when the system is not powered off, reducing the power outage time required for the maintenance of the arrester, greatly improving the reliability of power supply and equipment safety and reliability Improve the operation rate and use technical means to improve the service level of high-quality power supply. [0003] Patent document CN203659559U discloses a DC pole line arrester, which includes four arrester elements connected in series, a first voltage equalizing ring assembly and a second voltage equalizing ring assembly; the four arrester elements are respectively the first arrester elements connected in...
