Description

Technical Field

[0001] This utility model relates to the field of surge arrester monitoring technology, and more specifically, to a power surge arrester monitoring device. Background Technology

[0002] As an important safety device in the power system, the existence and application of surge arresters are intended to effectively protect power facilities from lightning overvoltage and switching overvoltage, and ensure the stable operation of the power grid and the continuity of power supply. In areas with frequent lightning activity or complex power system operating environments, the role of surge arresters is particularly prominent. They can quickly conduct lightning surge current into the ground, thereby protecting key equipment such as transformers and switchgear from damage.

[0003] However, traditional surge arrester monitoring methods rely heavily on manual inspections and periodic preventive tests. This means that maintenance personnel need to proactively conduct periodic inspections of surge arresters to assess their performance status and remaining lifespan. This inspection mode is not only time-consuming and labor-intensive, but may also lead to inaccurate inspection cycles or omission of potential fault points due to human factors, making it difficult to detect problems such as aging, moisture, or internal defects of surge arresters in a timely manner. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a power surge arrester monitoring device to solve the aforementioned problems.

[0005] This utility model is implemented as follows:

[0006] A power surge arrester monitoring device includes a mounting plate with a device mounting position and a surge arrester mounting position. The device mounting position is used to mount the monitoring device body, and the surge arrester mounting position is used to mount the surge arrester body. A probe support assembly is located at the center of the surge arrester mounting position. The probe support assembly includes several lifting brackets, and a slip ring mechanism is movably mounted at the center of the lifting brackets. The slip ring mechanism has a probe connection part for fixing the probe of the monitoring device body. A rotation mechanism is provided between the slip ring mechanism and the lifting brackets.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] like Figure 1-2 As shown, this utility model provides a power surge arrester monitoring device, including a mounting plate 30. The mounting plate 30 has a device mounting position 31 and a surge arrester mounting position 32. The device mounting position 31 is used to mount the monitoring device body 20, and the surge arrester mounting position 32 is used to mount the surge arrester body 10. A probe support assembly 40 is located at the center of the surge arrester mounting position 32. The probe support assembly 40 includes several lifting supports 41, and a slip ring mechanism 42 is movably mounted at the center of the lifting supports 41. The slip ring mechanism 42 has a mechanism for fixing the probe of the monitoring device body 20. A rotating mechanism 43 is provided between the probe connection part 4303, the slip ring mechanism 42 and the lifting bracket 41. The mounting plate 30 is also provided with a bracket control box 50 for controlling the operation of the probe lifting assembly. By placing the monitoring equipment body 20 near the surge arrester body 10 for real-time monitoring, and to avoid the fixed position of the probe on the monitoring equipment body 20, which would prevent the position of the surge arrester body 10 far from the probe from being undetectable, the probe bracket assembly 40 enables the probe position to change, thereby enabling it to detect the surge arrester body 10 from all directions and avoiding the problem of missing outgoing lines.

[0027] like Figure 3-6 As shown, the lifting bracket 41 includes a column 4101 and a transverse connecting arm 4104. The bottom of the column 4101 is fixed to the surge arrester mounting position 32 by bolts. A side groove is opened on one side of the column 4101 along the length direction. A lead screw 4102 is rotatably arranged in the side groove. A first drive motor 4103 is arranged on the top side of the column 4101. The rotating shaft of the first drive motor 4103 has a gear structure that meshes with the end of the lead screw 4102. One end of the transverse connecting arm 4104 is movably arranged on the lead screw 4102. When the lead screw 4102 is rotated, the transverse connecting arm 4104 moves in the vertical direction of the lead screw 4102.

[0028] Furthermore, the slip ring mechanism 42 includes an inner ring 4201 and an outer ring 4202 movably arranged together. The inner ring 4201 has a connecting plate fixedly connected to the transverse connecting arm 4104 inside. The probe connection part 4303 is located on the top side of the outer ring 4202. The slip ring mechanism is used in the prior art to solve the problem of transmitting power and signals between stationary and rotating equipment. Here, the slip ring mechanism 42 introduces this slip ring mechanism to realize the connection between the probe and the monitoring equipment body 20. Specifically, the probe's detection signal passes sequentially through the outer ring 4202, the inner ring 4201, and the terminal 52 in the bracket control box 50, and then is connected to the monitoring equipment body 20 by the corresponding data line, thereby realizing data transmission.

[0029] like Figure 6-7 As shown, a gear belt 4304 is provided on the side of the inner ring 4201, and a guide groove is provided at the bottom of the inner ring 4201. The rotating mechanism 43 includes a second drive motor 4301 and a guide wheel 4302. A transmission gear is provided at the rotating shaft of the second drive motor 4301. The second drive motor 4301 is fixedly installed on the side of the transverse connecting arm 4104 near the middle. The transmission gear meshes with the gear belt 4304. The guide wheel 4302 is fixedly installed on the side of the transverse connecting arm 4104 near the inner ring 4201. The guide wheel 4302 rolls in the guide groove.

[0030] Specifically, the lifting bracket 41 is used to move the probe vertically on the arrester body 10, while the combination of the slip ring mechanism 42 and the rotating mechanism 43 is used to move the probe horizontally on the arrester body 10. The combination of the two can enable the probe to explore the side of the arrester body 10 without blind spots, avoiding omissions.

[0031] like Figure 8 As shown, the bracket control box 50 includes a PLC controller 51, which is electrically connected to the first drive motor 4103 and the second drive motor 4301 respectively. The bracket control box 50 is also provided with a terminal block 52. The inlet wire of the terminal block 52 is connected to the inner ring 4201 through a wire, and the outlet wire of the terminal block 52 is connected to the monitoring device body 20 through a wire.

[0032] It should be noted that the PLC controller 51 is mainly used to control the running speed of several first drive motors 4103 and second drive motors 4301, so that they can transport the cyclic exploration along a fixed running route.

[0033] In this embodiment, there are several surge arrester mounting positions 32, and each surge arrester body 10 corresponds to a probe bracket assembly 40 and a bracket control box 50.

[0034] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
