Embodiment 1
[0030] Such as figure 1 As shown, a discharge counter online monitoring device that is easy to disassemble in the present invention includes a lightning arrester online monitoring box, and the lightning arrester online monitoring box includes an insulating installation shell 1 that can be installed with a discharge counter and an insert that is used in conjunction with the insulating installation shell 1 Fixture 2;
[0031] The insulating installation shell 1 includes a lower protection part 13, a backboard 11 installed on the online monitoring box of the arrester, and a cover 14 that can be opened and closed;
[0032] One side of the lower protection part 13 is fixedly connected to the backboard 11 , and the other end is connected to the cover 14 ;
[0033] A guide groove 15 for rotating the upper rotating part 12 along a predetermined path is provided at the joint between the lower protecting part 13 and the cover 14;
[0034] One side of the cover 14 is connected to the l...
Embodiment 2
[0040] Based on embodiment 1, the difference from embodiment 1 is:
[0041] The insulating mounting shell 1 further includes an upper rotating part 12 that can rotate relative to the lower protecting part 13 , one side of the upper rotating part 12 is connected to the back plate 11 , and the other end is connected to the cover 14 .
[0042] One end of the lower protection part 13 is provided with a limiting protrusion 131 , and the end of the upper rotating part 12 in a closed state is provided with a moving handle 121 at an end away from the limiting protrusion 131 .
[0043] The outer diameter of the upper rotating part 12 is smaller than the outer diameter of the lower protecting part 13 .
[0044] Further, the inner diameter of the upper rotating part 12 is larger than the inner diameter of the lower protecting part 13 , so that the upper rotating part 12 can be contained in the receiving groove of the lower protecting part 13 after being rotated. The rotation path of the...
