Description

A clamp-type flexible traveling wave sensor Technical Field

[0001] This utility model relates to the field of sensor technology, and specifically to a clamp-type flexible traveling wave sensor. Background Technology

[0002] Sensors are typically designed to be either open or closed, but both require some effort to replace the cable being tested, making them somewhat cumbersome. Existing technologies include C-type coil sensors to address some of these issues; however, existing sensors generally suffer from limitations in the applicable cable sizes. Temperature sensors are generally used to measure the temperature of the surface or contact points of high and low voltage energized objects, such as exposed contacts in high-voltage switchgear, busbar connections, outdoor disconnect switches, and the operating temperature of transformers. Summary of the Invention

[0003] The purpose of this invention is to provide a clamp-type flexible traveling wave sensor, which has a cable tie-type clamp structure. Compared with existing sensors with limited size, it can be better applied to various conductors under test, and has strong applicability and is safe and convenient to use.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a clamp-type flexible traveling wave sensor, including a clamp strap and a sensor body. One end of the clamp strap extends into the sensor body for fixation, and the other end is wrapped around a cable once and then passes through the clamp opening on the sensor body. The sensor body is also provided with a limiting component, which is used to lock the extension and sliding of the clamp strap relative to the clamp opening.

[0005] As a further provision of the above solution, the limiting component includes a top block, a moving block, and a locking screw. The front end of the locking screw abuts against the moving block, pushing the moving block closer to the top block. The moving block and the top block are located on the upper and lower sides of the clamp opening, respectively. The clamp band passes through the sensor body and is positioned between the moving block and the top block.

[0006] As a further provision of the above scheme, the moving block includes an abutment surface and a top spring post, and also includes a top spring member for pushing the moving block away from the top block.

[0007] As a further feature of the above solution, the sensor body is provided with a mounting groove and a cover plate. The mounting groove is provided with a nut groove and a nut. The locking screw is threadedly engaged with the nut that is fixed relative to the sensor body. The front end of the locking screw extends and retracts relative to the clamp band to push the moving block.

[0008] As a further feature of the above solution, the clamp strap is also provided with a square buckle.

[0009] Beneficial effects: The sensor of this utility model, through its clamp-type structural design, has a smaller measurement size range compared to existing sensors, making it more applicable to a wider range of testing scenarios. It avoids the problem of poor contact between the sensor and the surface of the object being measured due to loosening during long-term installation and use. The exposed part of the locking screw is equipped with a rod head with anti-slip texture, which is convenient for operators to rotate without the need for additional tools to tighten or loosen, making operation convenient.

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0014] As shown in Figure 1-2, a clamp-type flexible traveling wave sensor includes a clamp strap 2 and a sensor body 1. One end of the clamp strap 2 extends into the sensor body 1 for fixation, and the other end is wrapped around a cable and then passes through the clamp opening 11 on the sensor body 1. The sensor body 1 is also provided with a limiting component 3, which is used to lock the extension and sliding of the clamp strap 2 relative to the clamp opening 11.

[0015] As a further provision of the above scheme, the limiting component 3 includes a top block 31, a moving block 32, and a locking screw 33. The front end of the locking screw 33 abuts against the moving block 32, pushing the moving block 32 and the top block 31 closer together. The moving block 32 and the top block 31 are located on the upper and lower sides of the clamping opening 11, respectively. The clamping band 2 passes through the sensor body 1 and is located between the moving block 32 and the top block 31.

[0016] As a further provision of the above scheme, the moving block 32 includes an abutment surface 321 and a top spring post 322, and also includes a top spring member 34 for pushing the moving block 32 away from the top block 31.

[0017] As a further provision of the above scheme, the sensor body 1 is provided with a mounting groove 12 and a cover plate 4. The mounting groove 12 is provided with a nut groove 13 and a nut piece 14. The locking screw 33 is threadedly engaged with the nut piece 14 fixed relative to the sensor body 1. The front end of the locking screw 33 extends and retracts relative to the clamp band 2 to push the moving block 32.

[0018] As a further feature of the above solution, the clamp strap 2 is also provided with a square buckle 21.

[0019] Referring to Figure 2, the movable block 32 and the top block 31 of this embodiment are matched and fitted together to clamp the clamping band 2 under the push of the locking screw 33. When the locking screw 33 loosens and retracts, the movable block 32 is driven away from the top block 31 by the top spring 34 to release the locking clamp.

[0020] Referring to Figures 1-2, this utility model's sensor working principle and features are described. Compared to existing sensors, the sensor in this embodiment uses a clamp-type structure for installation on the surface of a cable or busbar. Compared to existing sensors, the sensor in this embodiment can adjust the measurement size range, making it more suitable for a wider range of testing scenarios. By changing the size of the clamp, the measurement can be adjusted freely within a certain range. The structure is compact and highly adaptable. Furthermore, a limiting component is provided, which locks the clamp 2 by rotating the locking screw 33. During long-term installation and use of the sensor in this embodiment, the limiting component 3 secures the clamp 2, preventing it from loosening. This reduces and avoids vibrations transmitted from the cable during use, and prevents the problem of loosening even when the clamp 2 is tightened due to unfavorable operating environments. This also avoids the problem of poor contact between the sensor and the surface of the object being measured due to loosening.

[0021] Furthermore, as shown in Figure 1, the exposed portion of the locking screw 33 in this embodiment is provided with a rod head with anti-slip texture, which makes it easy for operators to rotate. Based on the above, the sensor in this embodiment does not require additional tools to tighten or loosen, making it convenient to operate.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the technical solution of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
