Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, and in particular to a mounting bracket for a GIS partial discharge online monitoring sensor. Background Technology

[0002] In recent years, GIS equipment (gas-insulated fully enclosed switchgear, also known as gas-insulated switchgear) has been increasingly used in power systems due to its advantages such as aesthetics, small footprint, fewer malfunctions, and reliable operation.

[0003] A search revealed a patent with authorization announcement number CN202025025U, which discloses a mounting bracket for a GIS partial discharge online monitoring sensor. The bracket includes an end cap, a base, side plates, and a spring. The base is a rectangular prism with a cylindrical center and a through hole in the middle. The end cap is threaded onto the upper part of the base, and a spring is installed inside the end cap. Side plates are located on both sides of the base, and the base and side plates are bolted together. One side has a pre-drilled hole. The side plates are arc-shaped and have flange bolt holes and set screws for flange bolts. A groove is located on the upper part of the side plate to mate with the pre-drilled hole in the base. The end cap, base, and side plates are made of high-strength aluminum alloy with an oxidized surface, and the spring is made of stainless steel. This device has a simple structure, flexible installation, is convenient and practical, and offers high safety and reliability.

[0004] While the aforementioned bracket can effectively fix the sensor, it lacks adjustment functionality. When installed with flanges of different thicknesses, the distance between the base and the side plate cannot be adjusted, resulting in incompatibility and poor flexibility. Furthermore, due to the threaded connection between the end cap and the cylinder, and the friction between the spring and the sensor, the sensor can easily rotate via the spring when the end cap rotates. This can cause the sensor cable interface to misalign with the pre-drilled hole in the base, affecting subsequent wired connections of the sensor. Therefore, to address these issues, we propose a mounting bracket for a GIS partial discharge online monitoring sensor. Utility Model Content

[0005] The purpose of this utility model is to address the deficiencies in the existing technology by proposing a GIS partial-displacement online monitoring sensor mounting bracket.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A GIS localized online monitoring sensor mounting bracket includes an arc-shaped plate, a mounting cylinder is fixedly installed in the middle of the top of the arc-shaped plate, and a through hole is opened in the middle of the interior of the arc-shaped plate, the through hole communicating with the mounting cylinder;

[0008] A sensor is installed inside the mounting cylinder, and a detachable end cap is installed at the top of the mounting cylinder. A spring is fixedly installed on the top of the inner side of the end cap, and the bottom end of the spring abuts against the top of the sensor.

[0009] Two fixing components are fixedly installed on the front and rear sides of the top of the arc-shaped plate, and side plates are installed on the front and rear sides of the arc-shaped plate through the corresponding two fixing components.

[0010] Furthermore, an opening is provided on the front side of the mounting cylinder, and a cable interface is fixedly installed on one side of the sensor.

[0011] Furthermore, four protruding buckles are fixedly installed at equal intervals around the upper circumference of the outer surface of the mounting cylinder, and four buckle grooves are equally spaced around the bottom of the end cap. The buckle grooves are horizontally L-shaped and are adapted to the protruding buckles.

[0012] Furthermore, the fixing assembly includes screws and nuts, with four screws respectively fixedly installed at the four ends of the top of the arc-shaped plate, and the nuts threaded onto the upper ends of the four screws.

[0013] Furthermore, the side plate has sliding grooves on both the left and right sides of the top, and the side plate is slidably connected to two screws on one side of the arc plate through the two sliding grooves, with the nuts located at the top of the side plate.

[0014] Furthermore, the side plate has an arc-shaped structure, and two flange bolts are threaded on the front of the side plate. An arc-shaped groove is provided on the top of the side plate near the mounting cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The side plate can be moved back and forth via a sliding groove, changing the distance between the side plate and the arc plate. This allows for flexible adjustment based on the thickness of the flange and the basin insulator, providing high flexibility and ensuring accurate contact between the sensor and the basin insulator. By rotating the nut, the bottom end of the nut can be brought into contact with the top of the side plate, fixing the side plate in place and preventing relative movement between the side plate and the arc plate.

[0017] 2. The end cap can be quickly installed by means of the protruding buckle and the buckle groove, and the rotation range of the end cap is small, which can avoid the spring from causing the sensor to rotate a large range. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0026] Reference Figure 1-5 A GIS localized online monitoring sensor mounting bracket includes an arc-shaped plate 7, a mounting cylinder 1 fixedly mounted on the middle of the top of the arc-shaped plate 7, a through hole in the middle of the interior of the arc-shaped plate 7 communicating with the mounting cylinder 1; a sensor 2 is disposed inside the mounting cylinder 1, a detachable end cap 6 is mounted on the top of the mounting cylinder 1, a spring 13 is fixedly mounted on the top of the inner side of the end cap 6, and the bottom end of the spring 13 abuts against the top of the sensor 2; two fixing components are fixedly mounted on the front and rear sides of the top of the arc-shaped plate 7, and side plates 3 are mounted on the front and rear sides of the arc-shaped plate 7 through the corresponding two fixing components.

[0027] Sensor 2 is an existing GIS partial discharge online monitoring sensor. When installing sensor 2, first, the bottom of the arc plate 7 is attached to the outer edge of the basin insulator. At this time, the two side plates are located on both sides of the two flanges connected to the basin insulator. Two flange bolts are installed on the front thread of the side plate 3. Then, the flange bolts can be used to connect and fix it to the flanges on both sides of the basin insulator. The arc plate 7 and the two side plates 3 are fixed by the fixing assembly. Finally, the sensor 2 can be placed inside the mounting cylinder 1, and the end cap 6 is installed on the top of the mounting cylinder 1. The spring 13 will make the sensor 2 effectively contact the basin insulator under the action of elastic force, thereby completing the installation of the GIS partial discharge online monitoring sensor.

[0028] An opening 9 is provided on the front side of the mounting cylinder 1, and a cable interface is fixedly installed on one side of the sensor 2. The cable interface corresponds to the opening 9, which provides convenient conditions for wired transmission of the sensor 2.

[0029] Four protruding buckles 8 are fixedly installed on the upper circumference of the outer surface of the mounting cylinder 1 at equal intervals. Four buckle slots 12 are equally spaced around the bottom of the end cap 6. The buckle slots 12 are horizontally L-shaped and are adapted to the protruding buckles 8.

[0030] When installing the end cap 6 on the upper end of the mounting cylinder 1, first make the protruding buckle 8 enter the buckle groove 12, and then rotate the end cap 6 so that the protruding buckle 8 is fully inserted into the buckle groove 12. Through the protruding buckle 8 and buckle groove 12, the end cap 6 can be installed quickly, and the rotation range of the end cap 6 is small, which can avoid the spring 13 driving the sensor 2 to rotate a large range.

[0031] The fixing assembly includes screws 10 and nuts 4. Four screws 10 are fixedly installed at the four ends of the top of the arc-shaped plate 7. Nuts 4 are threaded onto the upper ends of the four screws 10. Sliding grooves 5 are provided on both the left and right sides of the top of the side plate 3. The side plate 3 is slidably connected to two screws 10 on one side of the arc-shaped plate 7 through two sliding grooves 5. Nuts 4 are located on the top of the side plate 3. The side plate 3 has an arc-shaped structure, and an arc-shaped groove 11 is provided on the side of the top of the side plate 3 near the mounting cylinder 1. The arc-shaped groove 11 is designed to prevent the side plate 3 from being interfered with by the mounting cylinder 1 during movement.

[0032] Side plate 3 can move back and forth via slide groove 5, changing the distance between side plate 3 and arc plate 7. This allows for flexible adjustment based on the thickness of the flange and the basin insulator, providing high flexibility and enabling sensor 2 to accurately contact the basin insulator. By rotating nut 4, the bottom end of nut 4 can abut against the top of side plate 3, fixing side plate 3 and preventing relative movement between side plate 3 and arc plate 7.
