specific Embodiment 1
[0042] Specific embodiment one: as figure 1 As shown, a lightning arrester device that is easy to install includes a bracket 1 , a lightning protection component 5 and an anti-loosening and anti-loosening device 4 .
[0043] 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.
[0044] The lightning protection assembly 5 includes a lightning arrester 5.1 fixed on a bracket, a lower conductive head 5.2 arranged on the upper end of the lightning arrester, an upper conductive head 5.3 located above the lower conductive head, and a conductive lead 5.4 electrically ...

The invention discloses lightning arrester equipment convenient to install. According to the lightning arrester equipment convenient to install,live-line installation is performed with an insulating rod operation method under the condition of not influencing normal operation of an overhead line. According to the prior art, a live-line operation vehicle needs to wait for installation of a lightning arrester in an area where passage of the live-line operation vehicle is inconvenient after power failure of the overhead line, and as a result, the normal operation of the overhead line is influenced. With thelightning arrester equipment convenient to install adopted, the above problem in the prior art can be solved. The equipment comprises a support, a lightning protection assembly and an anti-loosening and anti-falling device; 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; a fastening bolt is arranged in the bolt through hole; the lightning protection assembly comprises a lightning arrester fixed to the support, a lower conductive head arranged at the upper end of the lightning arrester, an upper conductive head located above the lower conductive head and a conductive lead electrically connected with the upper conductive head; a discharge gap is formed between the lower conductive head and the upper conductive head;.
Description
technical field [0001] The invention relates to a lightning arrester device, in particular to a lightning arrester device which is easy to install. 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 using t...
