Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to a retractable clamp for a vibration sensor of a high-voltage isolating switch. Background Art

[0002] High-voltage disconnectors play a vital role in power systems. They not only ensure the safety of workers, but also enable flexible scheduling and stable operation of power systems. During the opening and closing process, collisions and frictions will occur between the mechanical parts of the high-voltage disconnectors, which will cause vibrations. This mechanical vibration signal contains a lot of equipment status information. Therefore, by collecting and analyzing the vibration signal, the mechanical condition and opening and closing conditions of each component inside the disconnector can be effectively reflected.

[0003] Traditional high-voltage disconnector vibration sensors are mainly fixed with screws, glue, etc., which is not conducive to multi-point vibration monitoring of high-voltage disconnectors. Although screw fixing is firm, the screw holes need to be precisely aligned during installation, which is relatively cumbersome. Different types of glue may be required to fix the materials on the surfaces of different equipment. In addition, if the sensor needs to be replaced or adjusted frequently, traditional fixing methods will cause inconvenience. In some cases, it may be difficult to find an ideal installation location due to structural limitations or space limitations of the high-voltage disconnector. This may cause the sensor to be unable to accurately measure the vibration data of key parts, or the measurement data may be interfered with by other factors. Utility Model Content

It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for clarity, the thickness of the layers and regions is enlarged, and the same reference numerals are used to represent the same devices, so their description will be omitted.

[0019] See also Figures 1 to 3 The embodiment of the utility model provides a retractable clamp for a vibration sensor of a high-voltage disconnect switch, comprising: a vibration sensor 1, a retractable slide 2, a slide buckle 3 and a clamping part 4.

[0020] The clamping part 4 includes a first vibration sensor fixing block 41 and a second vibration sensor fixing block 42 which are arranged opposite to each other. A groove 43 is provided on the first vibration sensor fixing block 41 and the second vibration sensor fixing block 42 respectively. The vibration sensor 1 is fixed in the groove 43 .

[0021] The vibration sensor 1 is fixed in the slot 43 by bolt connection. The vibration sensor 1 is the core component of the clamp and is used to sense the vibration signal of the disconnector. The vibration sensor 1 is tightly connected to the clamping part 4 by bolts to ensure that the vibration sensor 4 can stably receive the vibration signal during the monitoring process.

[0022] The retractable slideway 2 is a key part of the clamp, which enables the clamp to adjust its length to adapt to high-voltage disconnectors at different positions or spacings. The retractable slideway 2 includes a slideway body 21 and grooves 22 arranged in sequence on the upper surface of the slideway body 21; one end of the slideway body 21 is connected to one end of the first vibration sensor fixing block 41, and the other end of the slideway body 21 is retractably connected to one end of the second vibration sensor fixing block 42. The retractable slideway 2 is located in the middle of the clamping part 4, as an adjustable part of the clamp, and is used to adapt to disconnectors of different sizes.

[0023] The end of the second vibration sensor fixing block 42 is provided with a jack, and the slide buckle 3 is a rectangular parallelepiped structure, and the shape of the jack at the end of the second vibration sensor fixing block 42 matches the cross-sectional shape of the slide buckle 3. The height of the jack at the end of the second vibration sensor fixing block 42 is consistent with the height of the groove 22, and the cross-sectional shape of the groove 22 matches the cross-sectional shape of the slide buckle 3. The slide buckle 3 is a device for adjusting and locking in order to ensure the accuracy and stability of the clamp, and is composed of a rectangular parallelepiped firmware. When the retractable slide 2 is adjusted to a suitable length, the slide buckle 3 can be inserted into the groove 22 of the slide to lock the clamp to prevent it from moving or loosening during use. The retractable slide 2 is connected to the clamping part 4 through the slide. After the length of the slide can be adjusted as needed, it can be locked with the slide buckle 3 to ensure that the clamp can accurately position and fix the vibration sensor 1. The slide buckle 3 allows the operator to fine-tune the position and angle of the clamp, and locks the clamp after it is adjusted in place to prevent it from moving or loosening during use.

[0024] The clamping part 4 is the main structure of the entire clamp, which is used to fix the vibration sensor 1 and connect the retractable slide 2. The other end of the first vibration sensor fixing block 41 and the other end of the second vibration sensor fixing block 42 are respectively provided with a clamping claw 44, which is made of high-strength sponge and is used to clamp and fix the clamp on the disconnector to ensure that the sensor remains stable during testing or monitoring. The clamping part 4 is tightly connected to the vibration sensor 1 to ensure that the vibration sensor 1 can stably receive the vibration signal. At the same time, the clamping part 4 is connected to the retractable slide to realize the retractable function of the clamp.

[0025] The working principle and use steps of the retractable clamp of the high-voltage disconnect switch vibration sensor of this embodiment are as follows:

[0026] First, according to the actual size of the high-voltage disconnector, adjust the retractable part of the fixture to ensure that the fixture can be tightly fixed on the disconnector to ensure the stability and accuracy of the fixture. Then install the vibration sensor in the slot of the fixture to ensure that the measurement direction of the sensor is consistent with the vibration direction of the disconnector. According to the wiring requirements of the vibration sensor, connect the cable and interface of the vibration sensor to ensure that the electrical connection is correct. Finally, start the vibration sensor and check whether its working status is normal to ensure that the vibration data of the disconnector can be accurately measured. Observe the fixing of the fixture and the vibration sensor to ensure that there is no loosening or falling off during the operation of the high-voltage disconnector, and then you can obtain the measurement data of the vibration sensor of the high-voltage disconnector at this time.

[0027] It can be seen from the above embodiments that the design of the retractable clamp of the high-voltage disconnector vibration sensor of the utility model enables it to adapt to high-voltage disconnectors of different sizes and shapes. By adjusting the length and width of the clamp, it can be conveniently fixed on the disconnector without replacing clamps of different specifications, thereby improving the flexibility and convenience of use. Moreover, the adjustment operation of the retractable clamp is relatively simple, and the clamp can be fixed and the vibration sensor can be installed only through simple telescopic and locking actions. This greatly saves the time of installation and debugging and improves work efficiency.
