Problems solved by technology
[0003] However, when the arrester on-line monitoring device is exposed to the outside world for a long time, problems such as internal component strain and failure will occur, and it needs to be replaced during the internal period. However, the structure of most arrester on-line monitoring devices at this stage is not conducive to Implementation of removal and replacement operations of internal components

Embodiment 1
[0020] Example 1, such as Figure 1 to Figure 5 shown. Since the on-line monitoring device of the arrester is often placed to work outdoors, however, the accumulated work over time and the outdoor changeable and harsh environment usually cause certain damage to the working components of the arrester, which will lead to the decline in the monitoring ability of the arrester or even failure For normal operation, the internal components need to be replaced. However, it is cumbersome to disassemble and install the internal components of most of the online monitoring devices for arresters on the market. Therefore, there is an urgent need for an online monitoring device for arresters that is easy to disassemble and assemble internal components. Specifically, Including the shell box and monitoring equipment, the monitoring equipment is placed in the shell box, wherein, the back, bottom and side panels of the shell box can be similar to the panels forming a cuboid shape, wherein, the s...

The invention relates to an online arrester monitoring device, and relates to the field of electrical equipment. The online arrester monitoring device comprises monitoring equipment and a shell box, wherein the shell box comprises a laminated shell and a rotatably opened door; the laminated shell comprises a side sliding part and multiple sections of arc plates; the side sliding part comprises a side sliding arc plate and a side sliding groove; the side sliding groove is formed by side sliding single grooves, the heights of which are progressively increased, in a connection manner; furthermore, the closer the rotatably opened door is, the shorter the side sliding single groove is; and the multiple sections of arc plates include a front extension plate and a rear bottom plate. The scalability of the outer structure of the device can be improved; and thus, disassembly and installation of a part in the device are convenient.
Description
technical field [0001] The invention relates to the field of electrical equipment, in particular to an online monitoring device for a lightning arrester. technical background [0002] During the continuous operation of the arrester for many years, the leakage current will cause its volt-ampere characteristics to change, which will lead to the aging of the valve plate of the zinc oxide arrester until thermal breakdown occurs. Internal damp or poor insulation performance of the internal insulating support will also increase the power frequency current and power consumption. In severe cases, it may cause internal discharge, which will cause the main equipment to be unprotected. In severe cases, an explosion may occur, affecting the safe operation of the system. The emergence of the arrester online monitoring device has changed the situation that the main equipment must be shut down for the pre-test. The real-time online monitoring of the arrester's operating parameters can be ...
