specific Embodiment 1
[0035] Specific embodiment one: as figure 1 As shown, a lightning arrester device capable of live installation includes a bracket 1 and a lightning arrester 5 .
[0036] The bracket 1 includes a top plate 1.1, a bottom plate 1.2 and a side plate 1.3 connecting the bottom plate and the top plate. The space between the top board, the bottom board and the side boards forms the cross-arm clamping groove 2. In this embodiment, the top plate is parallel to the bottom plate, and the side plates are perpendicular to the bottom plate. Bolt through holes are arranged on the base plate, and fastening bolts 3 are arranged on the bolt through holes.
[0037] The lightning arrester 5 includes an insulator 5.1, a conductive base 5.2 arranged at the lower end of the insulator, a conductive upper seat 5.3 arranged at the upper end of the insulator, a conductive lead wire 5.7 electrically connected with the conductive upper seat, and a drain rod 5.5. One end of the drain rod is electrically ...

The invention discloses a lightning arrester device capable of being installed in an electrified mode, and aims to provide a lightning arrester device capable of being installed in the electrified mode through an insulating rod operation method under the condition that normal operation of an overhead line is not affected, so that the problem the normal operation of the overhead line is affected due to the fact that the lightning arrester can be installed only after the overhead line is powered off in an area where the live working vehicle is inconvenient to pass through is effectively solved.The device comprises a support, wherein the support comprises a top plate, a bottom plate and a side plate connected with the bottom plate and the top plate, a cross arm clamping groove is formed in the space among the top plate, the bottom plate and the side plate, a bolt through hole is formed in the bottom plate, and a fastening bolt is arranged in the bolt through hole; and a lightning arrester which comprises an insulator, a conductive base arranged at the lower end of the insulator, a conductive upper seat arranged at the upper end of the insulator, a conductive lead electrically connected with the conductive upper seat and a drainage rod, and the lightning arrester is fixed on the bracket through the conductive base.
Description
technical field [0001] The invention relates to a lightning arrester device, in particular to a lightning arrester device capable of live installation. Background technique [0002] After the lightning arrester used on the overhead line is aging or damaged at present, since the lightning arrester in the prior art generally cooperates with the stud and the nut at the lower end of the lightning arrester, the lightning arrester is fixed on the cross arm of the pole. The studs are inserted into the mounting holes on the cross-arm of the pole from top to bottom, and then the nuts are installed on the studs, and the nuts are locked to fix the arrester on the cross-arm of the pole; due to specific installation, It is necessary to insert the studs at the lower end of the arrester into the installation holes on the cross-arm of the electric pole from top to bottom, which makes it impossible for the arrester in the prior art to be installed on the cross-arm of the electric pole by usi...
