Problems solved by technology

[0002] The existing on-line monitoring technology is generally connected to the discharge counter for the on-line monitoring of the arrester. The discharge counter is usually directly fixed on the equal-diameter pole, but the perennial wind and sun will greatly shorten the service life of the discharge counter.
And when the general discharge counter is repaired or replaced, the maintenance personnel need to use a screwdriver to remove the fixing screws one by one, which is time-consuming and labor-intensive, and may easily cause electric shock accidents

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...

Abstract

The invention relates to a power device, in particular to a discharge counter online monitoring device easy to detach. The device comprises a lightning arrester online monitoring box. The lightning arrester online monitoring box comprises an insulation mounting housing capable of mounting the discharge counter, and an insertion fixture used together with the insulation mounting housing. Accordingto the discharge counter online monitoring device, a cover is relatively rotatable relative to a lower protection portion through a hinge device; the cover is connected to the lower protection part through a locking device; and the cover can be fixed by inserting the insertion fixture. During maintenance, the maintenance and the disassembly of the discharge counter can be conveniently carried outonly need to pull out the insertion fixture, and maintenance personnel can work conveniently. Compared with a traditional mode, the electric shock risk of maintenance and disassembly of the dischargecounter is greatly reduced, and the personal safety is protected.

Description

technical field [0001] The invention relates to a power device, in particular to an easily disassembled discharge counter on-line monitoring device. Background technique [0002] Existing online monitoring technology generally connects discharge counters for online monitoring of surge arresters. The discharge counters are usually directly fixed on equal-diameter poles, but the perennial wind and sun will greatly shorten the service life of the discharge counters. And when the general discharge counter is maintained or replaced, the maintenance personnel need to use a screwdriver to remove the fixing screws one by one, which is time-consuming and labor-intensive, and easily causes electric shock accidents. Contents of the invention [0003] The purpose of the present invention is to provide an on-line monitoring device for a discharge counter that is easy to disassemble, easy to maintain and replace, and at the same time protect the personal safety of maintenance personnel....
