Description

Technical Field

[0001] This utility model belongs to the technical field of partial discharge detection structure, and in particular relates to a protective structure for mounting a partial discharge sensor array. Background Technology

[0002] Partial discharge is one of the main causes of insulation degradation in high-voltage power equipment. Partial discharge detection can identify potential insulation problems at an early stage, providing support for equipment maintenance. Ultra-high frequency (UHF) methods effectively avoid interference such as corona discharge in the field, offering high sensitivity and anti-interference capabilities, and facilitating live partial discharge detection, location, and defect type identification. Because UHF signals increase with propagation distance, efficient and accurate detection typically requires a sensor array, with coordinated detection achieved through the cooperation of the sensor arrays. Common partial discharge sensors are usually directly installed on the main body or supporting structures of various power equipment. While low in cost, they suffer from poor stability and customizability, making it difficult to effectively acquire complex partial discharge information. Utility Model Content

[0022] Mounting base 1, mounting plane 1a, first mounting hole 1b, glass cover 2, annular support platform 2a, insulating isolation plate 3, second mounting hole 3a, annular connecting platform 3b, mounting rod 4, sensor mounting hole 4a, locking nut 5, static grounding wire 6. Detailed Implementation

[0023] The present invention will be described in detail below with reference to specific embodiments.

[0024] This utility model discloses a partial discharge sensor array installation and protection structure, which is mainly used to provide a structure that can be installed and used independently without relying on the existing structure of electrical equipment. It can provide stable and effective installation positioning and isolation protection for the partial discharge sensor array. It adopts a simple and efficient assembly and fixing method, which is convenient to install and has low maintenance and use costs.

[0025] like Figure 1 As shown, its main structure includes a mounting base 1, a glass cover cylinder 2, an insulating isolation plate 3, a mounting rod 4, and a locking nut 5;

[0026] Mounting base 1 is fixedly installed, with a mounting plane 1a on its top and a first mounting hole 1b at the center of the top. Mounting base 1 is used as a basic support and fixing structure, and it is generally set on the ground foundation or other fixed structure. In this embodiment, mounting base 1 is a cup-shaped structure to achieve lightweight installation and use. Its bottom forms an installation space for installing various data cables and other structures, which is isolated from the upper sensor area to prevent interference and provide effective protection.

[0027] The glass cover 2 is vertically mounted on the mounting plane 1a, and the top of the glass cover 2 is provided with an annular support platform 2a. The use of a glass cover reduces the attenuation effect on electromagnetic waves and effectively isolates the sensor from the external dusty environment, preventing the tightly fitted sensor from being affected by external factors, and making maintenance and cleaning more convenient.

[0028] The insulating isolation plate 3 is inverted in a bowl shape on the annular support platform 2a. The insulating isolation plate 3 has a second mounting hole 3a in the center and an annular connecting platform 3b that fits into the annular support platform 2a on the edge. The upper and lower surfaces of the insulating isolation plate 3 are coated with an electromagnetic absorption coating.

[0029] The electromagnetic absorption coating is mainly formed by coating absorbing material to avoid multiple reflections of electromagnetic waves and reduce electromagnetic interference during detection.

[0030] The mounting rod 4 passes through the second mounting hole 3a and is inserted into the first mounting hole 1b. The mounting rod 4 is provided with a sensor mounting hole 4a on the rod body of the glass cover cylinder 2.

[0031] In order to provide a stable mounting surface and facilitate the alignment of the sensor, in this example, the mounting rod 4 is provided with a mounting surface on the rod body of the glass cover cylinder 2, and the sensor mounting hole 4a is located on the mounting surface.

[0032] Two locking nuts 5 are screwed into the mounting rod 4 from both ends and press the mounting base 1 and the insulating isolation plate 3 together.

[0033] Typically, as a sensor array mounting method, it includes multiple glass cover cylinders 2 and insulating isolation discs 3 sequentially fitted onto the mounting rod 4.

[0034] The use of insulating isolation disks can prevent electromagnetic interference within the detection range of the upper and lower glass covers, ensuring that the data from each sensor will not interfere with each other. At the same time, it also serves as a positioning support structure, ensuring the stability of the array itself.

[0035] In practical applications, depending on the actual situation, the glass cover, insulating isolation plate, and mounting base can be positioned and fixed together by means of slots, annular grooves, or other structures, which further improves the stability of the structure.

[0036] In particular, to avoid electromagnetic interference caused by electromagnetic induction and static electricity in the internal metal materials of the device when used in strong electromagnetic environments such as substations, the mounting rod 4 is made of insulating material in this embodiment.

[0037] In particular, a further improvement to the customizable installation structure of the aforementioned substation partial discharge sensor array is that the mounting base 1 is a cup-shaped structure with a hollow bottom forming an electronic space.

[0038] A static grounding wire 6 is specially designed to connect to the bottom of the mounting rod 4. The static grounding wire can conduct static electricity out of the device itself, preventing static interference and dust adsorption caused by static electricity.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
