Description

Technical Field

[0001] This utility model relates to the field of partial discharge detection technology, and more specifically, to a partial discharge sliding detection device. Background Technology

[0002] In the field of power systems, the safe and stable operation of electrical equipment is crucial to the reliability of the entire system, and partial discharge, as a common and harmful phenomenon, is receiving increasing attention.

[0003] Currently, traditional partial discharge detection methods have many limitations. On the one hand, the fixed installation of sensors, like a predetermined technical model, cannot adapt to the needs of different equipment and environments, resulting in the detection range not being able to fully cover different parts of various equipment, and the detection accuracy being difficult to meet actual needs. On the other hand, partial discharge signals themselves are highly complex, with variable characteristic parameters and are easily affected by various factors. This makes precise adjustment of the sensor position a necessary condition for obtaining the best detection results in existing detection technologies. However, this precise adjustment process often requires professional technicians to operate based on experience, which not only consumes a lot of time and manpower, but also results in poor detection flexibility and accuracy. Utility Model Content

[0004] The present invention aims to provide a partial discharge sliding detection device to solve the problems of inaccurate sensor position adjustment, poor detection efficiency, small detection range, low detection accuracy, and low detection flexibility and accuracy in the prior art.

[0005] The embodiments of this utility model are implemented as follows:

[0006] This utility model provides a partial discharge sliding detection device, which includes a fixing mechanism;

[0007] The aforementioned fixing mechanism has a detection mechanism inside and a sliding mechanism at the bottom. The fixing mechanism and the sliding mechanism are slidably connected to each other and can be fixed together.

[0008] The aforementioned sliding mechanism has a slide rail, with a track at the center of the slide rail, and a sliding support component is slidably connected inside the track.

[0009] In use, the aforementioned detection mechanism is fixedly installed inside the aforementioned fixing mechanism. The aforementioned slide rail of the aforementioned sliding mechanism is installed on the surface of the GIS pipeline or other power equipment. For pipeline structures, it directly connects around the pipeline. The aforementioned track is set in the center of the aforementioned slide rail. One end of the aforementioned sliding support component is set inside the aforementioned track, and the other end is connected to the aforementioned fixing mechanism to achieve a sliding connection. Depending on the size, it can wrap around the pipeline or cover a part of the area. The aforementioned detection mechanism can slide on the aforementioned sliding mechanism through the aforementioned fixing mechanism to change the detection position of the aforementioned detection mechanism, and can be fixed by the aforementioned fixing mechanism to achieve partial discharge signal detection.

[0010] The partial discharge sliding detection device disclosed in this embodiment facilitates the adjustment and quick fixing of the detection position of the detection mechanism due to the sliding cooperation between the detection mechanism and the sliding mechanism. This results in a partial discharge sliding detection device with the following beneficial effects: the sensor position can be precisely adjusted, it can adapt to various power equipment, it improves detection efficiency, expands the detection range, improves detection accuracy, improves detection flexibility, and improves detection accuracy.

[0011] Optionally: The fixing mechanism has a fixing frame, which is disposed at the upper end of the slide rail and slides in cooperation with the rail through the sliding support component. A first strap and a second strap are provided between the two ends of the fixing frame. The outer ends of the first strap and the second strap are fixedly connected to the two ends of the fixing frame respectively. A connecting buckle is elastically connected between the inner ends of the first strap and the second strap. The detection mechanism is disposed inside the fixing frame and at the lower end of the first strap and the second strap.

[0012] With this configuration, the length and width of the aforementioned fixing frame can be extended and adjusted, and fixed by threads. The aforementioned first strap and the aforementioned second strap are elastic and can be extended when fixing the aforementioned testing mechanism to adapt to testing mechanisms of different sizes. The aforementioned first strap and the aforementioned second strap are fixedly connected by the aforementioned connecting buckle.

[0013] Optionally, the sliding support assembly has a sliding rod disposed inside the track and fixedly connected to the fixing frame, and a limiting member for clamping or releasing the slide rail is fixedly connected to one side of the sliding rod.

[0014] With this configuration, one end of the sliding rod extends into the track, and the other end of the sliding rod is connected to the lower ends of both sides of the fixed frame. The sliding rod and the fixed rod are connected by a pin. The fixed frame slides along the track under the action of the sliding rod. When the fixed frame slides to a fixed position, the limiting member is used to limit the position of the fixed frame, maintain the stability of the detection mechanism, facilitate the control of the displacement of the detection mechanism, facilitate the fixation of the detection mechanism, and prevent the detection mechanism from moving accidentally during detection, thereby avoiding affecting the detection data.

[0015] Optionally, the limiting member has an extension rod, one end of which is fixed to the sliding rod, and the other end of which extends toward the side of the slide rail and has a limiting hole. A bolt is fitted in the limiting hole, and the bolt is rotatably abutted against the side of the slide rail.

[0016] With this configuration, the extension rod slides from the side of the sliding rod toward the side of the slide rail, slides to the side edge of the slide rail and bends toward the side edge of the slide rail, and the bolt is turned into the limiting hole. The bolt extends toward the slide rail and abuts against the side edge of the slide rail, thereby fixing the bracket.

[0017] Optionally: the slide rail is a flexible strip structure, the two ends of the slide rail are connected to each other to form a ring structure, and the track is located on one side of the outer ring of the slide rail.

[0018] This configuration facilitates the installation of the aforementioned slide rails on the surface of the GIS pipeline, making it convenient for the aforementioned testing agencies to conduct inspections around the GIS pipeline.

[0019] Optionally, the side end face of the slide rail is provided with a buckle for locking the connection between the two ends of the slide rail.

[0020] With this configuration, when the length of the slide rail is greater than the circumference of the pipe, the tail end of the slide rail can extend into the head end of the slide rail, and then the buckle locks the slide rail to form a ring covering the pipe; when the length of the slide rail is insufficient to cover the circumference of the pipe, the slide rail is connected into a ring structure by a strap, which facilitates the precise adjustment of the sensor position in the detection mechanism to obtain the best detection effect.

[0021] Optionally, the slide rail is provided with a connecting groove in the radial direction, the connecting groove is provided on both sides of the track, and the end of the sliding rod near the track passes through the connecting groove and is limited within the track.

[0022] This configuration allows the fixing mechanism to be slidably connected to the sliding mechanism, enabling the fixing mechanism to move while preventing it from detaching from the sliding mechanism. This facilitates precise adjustment of the sensor position in the detection mechanism to achieve the best detection results.

[0023] Optionally, an arc-shaped piece is fixedly connected to one end of the sliding rod near the track. The arc-shaped piece is adapted to the connecting groove and is limited within the track by the connecting groove.

[0024] With this configuration, the width of the arc-shaped piece is greater than the width of the track. Therefore, after the sliding rod extends the arc-shaped piece into the track from the connecting groove, the arc-shaped piece will not fall out of the track. It can only detach from the track at the connecting groove, ensuring the stability of the sensor position adjustment.

[0025] Optionally: The above-mentioned fixing frame has a cuboid hole in the middle, and the above-mentioned detection mechanism is securely arranged inside the cuboid hole.

[0026] With this design, the aforementioned cuboid holes facilitate the fixing of sensors in the aforementioned detection mechanism, making it convenient to test electrical equipment.

[0027] Optionally, the aforementioned extension rod has a plurality of bamboo-joint connecting rods that are telescopically connected in sequence.

[0028] With this configuration, the length of the extension rod can be changed through several bamboo-joint connecting rods, making it easy to clamp or release the slide rail.

[0038] Example

[0039] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment proposes a partial discharge sliding detection device, including a fixing mechanism 1;

[0040] The fixing mechanism 1 has a detection mechanism 2 inside and a sliding mechanism 3 at the bottom. The fixing mechanism 1 and the sliding mechanism 3 are slidably connected to each other and can be fixed together.

[0041] The sliding mechanism 3 has a slide rail 4, and a track 5 is provided in the center of the slide rail 4. A sliding support component 6 is slidably connected inside the track 5.

[0042] In use, the detection mechanism 2 is fixedly installed inside the fixed mechanism 1. The slide rail 4 of the sliding mechanism 3 is installed on the surface of the GIS pipe or other power equipment. For pipe-type structures, it directly connects around the pipe. The track 5 is set in the center of the slide rail 4. One end of the sliding support component 6 is set inside the track 5, and the other end is connected to the fixed mechanism 1 to realize the sliding connection. Depending on the size, it can wrap around the pipe or cover part of the area. The detection mechanism 2 can slide on the sliding mechanism 3 through the fixed mechanism 1 to change the detection position of the detection mechanism 2. It can also be fixed by the fixed mechanism 1 to realize the detection of partial discharge signals.

[0043] The partial discharge sliding detection device disclosed in this embodiment facilitates the adjustment and quick fixing of the detection position of the detection mechanism 2 due to the sliding cooperation between the detection mechanism 2 and the sliding mechanism 3. This results in a partial discharge sliding detection device with the following beneficial effects: the sensor position can be precisely adjusted, it can adapt to various power equipment, it improves detection efficiency, expands the detection range, improves detection accuracy, improves detection flexibility, and improves detection accuracy.

[0044] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The fixing mechanism 1 has a fixing frame 7, which is set on the upper end of the slide rail 4 and slides with the rail 5 through the sliding support component 6. A first strap 8 and a second strap 9 are provided between the two ends of the fixing frame 7. The outer ends of the first strap 8 and the second strap 9 are fixedly connected to the two ends of the fixing frame 7 respectively. The inner ends of the first strap 8 and the second strap 9 are elastically connected by a connecting buckle 10. The detection mechanism 2 is set inside the fixing frame 7 and at the lower end of the first strap 8 and the second strap 9. The length and width of the fixing frame 7 can be adjusted and fixed by threads. The first strap 8 and the second strap 9 are elastic and can be extended when fixing the detection mechanism 2 to adapt to detection mechanisms 2 of different sizes. The first strap 8 and the second strap 9 are fixedly connected by the connecting buckle 10.

[0045] The sliding support assembly 6 has a sliding rod 11, which is disposed inside the track 5 and fixedly connected to the fixing frame 7. A limiting member 12 for clamping or releasing the slide rail 4 is fixedly connected to one side of the sliding rod 11. One end of the sliding rod 11 extends into the track 5, and the other end of the sliding rod 11 is connected to the lower ends of both sides of the fixing frame 7. The sliding rod 11 and the fixing rod are connected by a pin. The fixing frame 7 slides along the track 5 under the drive of the sliding rod 11. When the fixing frame 7 slides to the fixed position, the limiting member 12 is used to limit the position of the fixing frame 7, maintain the stability of the detection mechanism 2, facilitate the control of the displacement of the detection mechanism 2, facilitate the fixing of the detection mechanism 2, and prevent the detection mechanism 2 from moving accidentally during detection, thereby avoiding affecting the detection data.

[0046] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting member 12 has an extension rod 13. One end of the extension rod 13 is fixed to the sliding rod 11. The other end of the extension rod 13 extends toward the side of the slide rail 4 and has a limiting hole 14. A bolt 15 is fitted in the limiting hole 14. The bolt 15 is rotatably abutted against the side of the slide rail 4. The extension rod 13 slides from the side of the sliding rod 11 toward the side of the slide rail 4, slides to the side edge of the slide rail 4 and bends toward the side edge of the slide rail 4. The bolt 15 is turned into the limiting hole 14. The bolt 15 extends toward the slide rail 4 and abuts against the side edge of the slide rail 4, thereby achieving a fixed connection to the fixing frame 7.

[0047] The slide rail 4 is a flexible strip structure. The two ends of the slide rail 4 are connected to each other in a ring structure. The track 5 is located on one side of the outer ring of the slide rail 4. This makes it easy for the slide rail 4 to be installed on the surface of the GIS pipeline, and facilitates the inspection agency 2 to carry out inspection around the GIS pipeline.

[0048] The side end face of the slide rail 4 is provided with a buckle 16 for locking the end connection of the slide rail 4. When the length of the slide rail 4 is greater than the circumference of the pipe, the tail end of the slide rail 4 can be inserted into the head end of the slide rail 4. Then, the buckle 16 locks the slide rail 4, forming a ring covering the pipe. When the length of the slide rail 4 is not long enough to cover the circumference of the pipe, the slide rail 4 is connected into a ring structure by a strap, which makes it easy to accurately adjust the position of the sensor in the detection mechanism 2 to obtain the best detection effect.

[0049] The slide rail 4 has a connecting groove 17 on its radial side. The connecting groove 17 is located on both sides of the track 5. The end of the sliding rod 11 near the track 5 passes through the connecting groove 17 and is limited within the track 5. This allows the fixing mechanism 1 to be slidably connected to the sliding mechanism 3, so that the fixing mechanism 1 can move while avoiding detachment from the sliding mechanism 3. This facilitates the precise adjustment of the sensor position in the detection mechanism 2 to obtain the best detection effect.

[0050] An arc-shaped piece 18 is fixedly connected to one end of the sliding rod 11 near the track 5. The arc-shaped piece 18 is adapted to the connecting groove 17 and is limited within the track 5 by the connecting groove 17. The width of the arc-shaped piece 18 is greater than the width of the track 5. Therefore, after the sliding rod 11 extends the arc-shaped piece 18 into the interior of the track 5 through the connecting groove 17, the arc-shaped piece 18 will not fall out of the interior of the track 5, but can only detach from the track 5 at the connecting groove 17, thus ensuring the stability of the sensor position adjustment.

[0051] See Figure 1 , Figure 2 , Figure 3 and Figure 4The mounting bracket 7 has a cuboid hole 19 in the middle. The detection mechanism 2 is securely arranged inside the cuboid hole 19. The cuboid hole 19 facilitates the fixing of the sensor in the detection mechanism 2, making it convenient to detect electrical equipment.

[0052] The extension rod 13 has several bamboo-joint connecting rods 20 that are connected in a series of telescopic links. The extension rod 13 changes its length through the bamboo-joint connecting rods 20, which makes it easy to clamp or release the slide rail 4.

[0053] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The specific operating principle of the partial discharge sliding detection device in this embodiment is as follows:

[0054] First, the slide rail 4 of the sliding mechanism 3 is installed on the surface of the GIS pipe, either around the pipe or covering a portion of the area, depending on the size. For pipe-like structures, it is directly connected around the pipe. The track 5 is set in the center of the slide rail 4. One end of the sliding support component 6 is set inside the track 5, and the other end of the sliding support component 6 is connected to the fixing mechanism 1, so that the fixing mechanism 1 can support the detection mechanism 2 to slide on the sliding mechanism 3. When detection is required, the fixing mechanism 1 is pushed to slide on the sliding mechanism 3. When it slides to the optimal detection position, several bamboo joint connecting rods 20 tighten, and the bolts 15 inside the limiting hole 14 rotate and abut against the side edge of the slide rail 4, thus fixing the connection of the fixing frame 7. In this way, the position of the UHF sensor in the detection mechanism 2 is fixed, which facilitates the detection of partial discharge signals. If the detection mechanism 2 needs to be replaced, the first strap 8 and the second strap 9 are separated by opening the connecting buckle 10, and the detection mechanism 2 can be taken out from the cuboid hole 19 for replacement.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
