DETAILED DESCRIPTION

[0023] The utility model discloses a lightning arrester test device, which is shown in the following figure in conjunction with the preferred embodiment (Example 1). Figure 1-7 , the specific implementation methods of the utility model are further described.

[0024] Example 1.

[0025] See attached figure Figures 1 to 6 , Figures 1 to 4 The arrester test device is shown in different perspectives. Figure 5 and Figure 6 Partially enlarged structures of the suspension assembly 100 and the adjustment assembly 200 are shown respectively.

[0026] Preferably, the arrester test device is used to simultaneously test multiple arresters 200 to be tested. The arrester test device includes multiple suspension assemblies 100 and multiple adjustment assemblies 200 connected end to end to form a ring. An adjustment assembly 200 is provided between two adjacent suspension assemblies 100, and another suspension assembly 100 is provided between two adjacent adjustment assemblies 200, so that the suspension assemblies 100 and the adjustment assemblies 200 are adjacent to each other and spaced apart.

[0027] The suspension assembly 100 includes a suspension cable 110 and a hanger 120 for suspending (one) arrester 300 to be tested. The hanger 120 includes a hanger body 140 and a suspension structure 130 located on one side of the hanger body 140. The hanger body 140 is fixedly connected to the suspension structure 130. One end of each suspension cable 110 of each suspension assembly 100 is connected to the other suspension cables 110 (at the same position so as to be connected to an external device), thereby suspending the entire arrester test device. The other end of each suspension cable 110 of each suspension assembly 100 is detachably connected to the suspension structure 130 (of the suspender 120) of the suspension assembly 100; when multiple suspension assemblies 100 simultaneously suspend corresponding arresters 300, each suspension cable 110 is in a taut state, so that there is a distance between adjacent arresters 300 to be tested (and the distance can be fine-tuned by the adjustment assembly 200), thereby avoiding mutual interference between adjacent arresters 300 to be tested, which may cause test abnormalities;

[0028] The adjustment assembly 200 includes an adjustment top plate 210, an adjustment bottom plate 220 and a plurality of positioning bolts 240. The hanger body 140 includes a hanger top plate 141 and a hanger bottom plate 142. The hanger top plate 141 and the hanger bottom plate 142 together form a suspension space 143 for just accommodating the lightning arrester 300 to be tested. The hanger top plate 141 is movably connected to the adjustment top plate 210 (to a limited extent) via the positioning bolts 240, and the hanger bottom plate 142 is movably connected to the adjustment bottom plate 220 (to a limited extent) via the positioning bolts 240. The suspension assembly 100 and the adjustment assembly 200 are connected end to end to form a ring, and the spacing between adjacent lightning arresters 300 to be tested can be fine-tuned by the adjustment assembly 200 (the relative position of the suspension assembly 100 with respect to the adjacent adjustment assemblies 200 is adjusted by the positioning bolts 240).

[0029] The suspender top plate 141 has a groove 150 for accommodating the suspending structure 130 , so that the suspending structure 130 is embedded in the suspender top plate 141 .

[0030] Among them, the suspension structure 130 includes a step portion 131 and a T-shaped extension portion 132 fixedly connected to the step portion 131. A snap portion 133 is provided on the side of the T-shaped extension portion 132 away from the step portion 131, and the suspension cable 110 (one end) is snap-connected with the snap portion 133; after the suspension cable 110 is snap-connected with the snap portion 133, the suspension cable 110 and the hanger 120 have sufficient connection strength to support the entire lightning arrester test device suspended in mid-air; at the same time, when the lightning arrester test is completed, the suspension cable 110 can be separated from the snap portion 133 to facilitate the storage of the suspension cable 110.

[0031] The suspension assembly 100 further includes a plurality of wire harnesses 160 and a plurality of wire harness interfaces 180 , and two ends of the wire harness 160 are respectively connected to different wire harness interfaces 180 .

[0032] Among them, the adjustment component 200 also includes a connecting block 230, which is located between the adjustment top plate 210 and the adjustment bottom plate 220, so that the connecting block 230 is connected to the adjustment top plate 210 and the adjustment bottom plate 220 at the same time, so that the adjustment component 200 retains the adjustment margin while having good overall strength, preventing the entire lightning arrester test device from being suspended in mid-air due to local deformation caused by excessive overall strength, and being unable to effectively maintain the suspension space 143 for accommodating the lightning arrester 300 to be tested.

[0033] Among them, the hanger top plate 141 and the hanger bottom plate 142 respectively have several positioning holes 170, so that the relative position between the suspension component 100 and the adjacent adjustment component 200 can be movably connected with the positioning blocks 170 at different positions through the positioning bolts 240.
