Description

Technical Field

[0001] This utility model relates to the technical field of online monitoring devices for surge arresters, and in particular to an online monitoring device for surge arresters. Background Technology

[0002] The surge arrester online monitoring device collects the surge arrester's operating parameters in real time through high-precision sensors (such as zero-flux sensors), including total current, resistive current, and capacitive current. Then, the current signal is converted into a frequency signal through a current / frequency conversion circuit for long-distance transmission. The processed signal is transmitted to the signal receiving and processing circuit via optical fiber or other communication methods. Optical fiber transmission can achieve high-voltage isolation and long-distance transmission, ensuring the accuracy and security of the data. The signal processing circuit at the receiving end further processes and analyzes the received data, improving measurement accuracy through digital filtering and multi-channel collaborative sampling technology. The processed data is displayed on the screen through a display module for easy viewing and monitoring by staff.

[0003] Existing surge arrester monitoring devices mostly consist of monitoring cabinets connected to the surge arresters via data cables. These cabinets collect and analyze operational data in real time to determine the arrester's operating status. However, these existing monitoring devices require opening the door and disassembling the bolts of the internal processing equipment before removing the device for maintenance. This is inconvenient, and the lack of a proper wiring structure leads to messy internal wiring, complicating maintenance and increasing time. Therefore, an online surge arrester monitoring device is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An online monitoring device for surge arresters includes a surge arrester online testing equipment enclosure. A wall-mounted assembly is provided on the left side of the inner wall of the surge arrester online testing equipment enclosure. The wall-mounted assembly includes a wall-mounted plate. Two guide rails are symmetrically connected to the right side of the wall-mounted plate, and a hanging plate is slidably installed on the surface of the guide rails. A display monitoring panel is installed on the right side of the hanging plate.

[0007] Preferably, the inner wall of the front opening of the surge arrester online testing equipment enclosure is provided with a sliding groove, and a door panel is slidably installed in the sliding groove. Two locking plates are symmetrically connected to the right side of the inner wall of the surge arrester online testing equipment enclosure. The door panel can slide sideways to facilitate the maximum visual display of the internal space of the surge arrester online testing equipment enclosure.

[0008] Preferably, the guide rail is composed of a cylindrical slide rail end and a T-shaped plate end. A handle is connected to the bottom right side of the hanging plate. The hanging plate can be suspended and installed through the cylindrical slide rail end of the guide rail, so that the hanging plate can slide on the surface of the cylindrical slide rail end of the guide rail. The cylindrical slide rail end of the guide rail also helps to ensure the smoothness of the hanging plate when moving.

[0009] Preferably, an auxiliary support plate is connected to the right side of the hanging plate, and the right side of the front of the auxiliary support plate is connected and fixed to the display monitoring panel by bolts. By fixing the auxiliary support plate to the right side of the hanging plate, the auxiliary support plate can provide auxiliary support for the display monitoring panel, effectively reducing the downward force of the display monitoring panel and ensuring the stability of the display monitoring panel when it is suspended.

[0010] Preferably, the surface of the auxiliary support plate is provided with a groove, and a through air channel is formed between the groove of the auxiliary support plate and the display monitoring panel. The through air channel between the auxiliary support plate and the display monitoring panel allows heat to be quickly dissipated through the through air channel.

[0011] Preferably, a wire harness assembly is provided at the bottom right side of the suspension plate. The wire harness assembly includes a suspension plate, and a constraint component is embedded in the surface of the suspension plate through a guide groove. The constraint component includes a slider, and a wire clip is connected to the front of the slider. The slider can be guided by the guide groove of the suspension plate to ensure the smoothness of the slider during movement.

[0012] Preferably, the wire clamp has two guide plates symmetrically installed on its front side, and multiple wire harness pressure plates are equidistantly arranged on the inner wall of the wire clamp. A constraint groove is formed between two adjacent wire harness pressure plates. Through the design of multiple wire harness pressure plates in the wire clamp, the wire harness grooves of two adjacent wire harness pressure plates can clamp the wire harness, ensuring the constraint stability of the wire harness.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By setting up a wall-mounted assembly, the display monitoring panel can be easily pulled out for maintenance. Compared with the traditional structure, this device is fixed to the inner wall of the surge arrester online testing equipment box by a wall-mounted plate, so that the hanging plate slides on the surface of the wall-mounted plate. By pulling the handle, the display monitoring panel can be moved, and then the display monitoring panel can be moved out of the surge arrester online testing equipment box, ensuring the portability of the display monitoring panel and improving the convenience of maintenance. At the same time, an auxiliary support plate is set on the right side of the wall-mounted plate, which can support and fix the display monitoring panel to ensure the stability of the display monitoring panel when suspended.

[0015] 2. By setting up a wire harness assembly, the wire harness can be classified and constrained for installation. This device is fixed to the inside of the hanging plate by a suspension plate. The slider moves in the guide groove of the suspension plate, thereby changing the position of the wire clip. The wire harness pressure plate can be used to separate the wire harness. The suspension plate and the hanging plate are connected, which can facilitate the synchronous movement of the wire harness with the hanging plate. The wire harness pressure plate has a T-shaped structure design. The T-shaped horizontal plate ends of two adjacent wire harness pressure plates can limit the movement and prevent the wire harness from being easily pulled out. Attached Figure Description
