Description

Technical Field

[0001] The invention relates to the technical field of power equipment maintenance, and in particular to a GIS conductor loop resistance measurement transition device. Background Art

[0002] With the implementation of standardized equipment maintenance, the maintenance work of GIS equipment is increasing. According to the requirements of the power equipment maintenance test procedures, it is necessary to regularly test the conductive loop resistance of circuit breakers, GIS intervals and busbars. When an abnormality is found on site, it is necessary to further narrow the interval and confirm the specific location of the defect. When it involves the main conductor, it is often necessary to open the cover for measurement. There are many GIS products at present, with different structures, conductor sizes and shapes, and narrow space after opening the cover. The loop electrical test clamps often cannot be directly engaged with the conductor surface: because the opening angle of the clamp is limited, and there is a concern that the conductor will be damaged during engagement, resulting in metal debris remaining in the air chamber. At this time, the clamp head is generally overlapped on the conductor surface to complete the test. The test data varies a lot, is not accurate and stable enough, and is not convenient for on-site judgment of the authenticity and validity of the data.

[0003] Therefore, it is necessary to improve the existing technology.

[0034] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in this field, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art. After continuous research and design, and after repeated trial production and improvement, the present invention with real practical value was finally created.

[0035] Please refer to Figure 1 The embodiment of the present invention provides a GIS conductor loop resistance measurement transition device, which mainly includes two major components: a belt body 1 and a buckle 2.

[0036] Specifically, the buckle 2 is cleverly arranged at one end of the belt body 1, and the two cooperate with each other to form a unique locking connection mechanism. Through this design, the belt body 1 and the buckle 2 can be tightly connected to form a ring structure that can be flexibly wrapped around the outer surface of the GIS conductor.

[0037] The GIS conductor loop resistance measurement transition device provided in the embodiment of the present invention has significant advantages in terms of function and practicality. On the one hand, it can ensure good contact with the GIS conductor, ensuring the accuracy of the measurement; on the other hand, during the contact process, the device will not cause any damage to the conductor surface, while avoiding the generation of metal foreign matter, ensuring the safe operation of the GIS equipment.

[0038] For operation and maintenance personnel, the emergence of this device has greatly improved their work efficiency. With its convenient operation and high reliability, operation and maintenance personnel can quickly and accurately measure the loop resistance data within the GIS equipment area, providing strong support for equipment maintenance and overhaul.

[0039] In addition, the GIS conductor loop resistance measurement transition device of the present invention has wide applicability. It is not only suitable for conventional GIS equipment loop resistance testing work, but also shows unique value in special scenarios where the condition of the body conductor needs to be confirmed after opening the cover. Therefore, we have reason to believe that this device will have broad application prospects in future GIS equipment operation, maintenance and testing work.

[0040] In one implementation of this embodiment, the belt body 1 is designed to be slender and flat. This design not only enables the belt body 1 to flexibly adapt to the curvature changes of various GIS conductor surfaces, ensuring good fit and contact area, but also improves the accuracy of loop resistance measurement;

[0041] At the same time, the slender and flat shape also makes it easier for operation and maintenance personnel to wrap and fix it during actual operations, thereby improving work efficiency.

[0042] In addition, this design also helps to reduce the friction and damage that the belt body 1 may cause to the surface of the GIS conductor during the winding process, ensuring the safe and stable operation of the GIS equipment.

[0043] In summary, the design of the slender flat belt body 1 is an important technical innovation in the embodiment of the present invention, which provides a more reliable and efficient solution for measuring the loop resistance of GIS conductors.

[0044] In one implementation of this embodiment, a clip hole matching with the clip 2 is provided on the belt body 1 .

[0045] It should be noted that this design makes the connection between the belt body 1 and the buckle 2 more stable and easy to operate. The mutual engagement of the buckle hole and the buckle not only ensures that the entire transition device can form a tight ring structure after being wrapped around the surface of the GIS conductor, but also prevents the loosening or falling off that may occur during the measurement process, thereby ensuring the accuracy and safety of the measurement;

[0046] At the same time, the matching mode of the buckle and the hole greatly simplifies the assembly and disassembly process of the device, allowing the operation and maintenance personnel to complete the measurement of the GIS conductor loop resistance more conveniently and efficiently in actual operation.

[0047] Therefore, the clamping hole provided on the belt body 1 is a crucial technical innovation in the embodiment of the present invention, which further improves the practicality and convenience of the transition device.

[0048] In one implementation of this embodiment, the loop resistance of the device is less than 20 μΩ.

[0049] The setting of this technical indicator fully demonstrates the excellent performance of the embodiment of the present invention in improving measurement accuracy and ensuring data reliability.

[0050] Specifically, a loop resistance of less than 20μΩ means that when the transition device is connected to the GIS conductor loop for measurement, the resistance value introduced by itself is extremely low and almost negligible. In this way, the loop resistance data measured by the operation and maintenance personnel through the device will be closer to the actual resistance value of the GIS conductor loop, thereby greatly improving the accuracy and credibility of the measurement results.

[0051] In addition, the setting of the loop resistance less than 20μΩ also reflects the superb skills of the embodiment of the present invention in material selection and structural design. By adopting high-conductivity materials and optimized structural design, the present invention successfully reduces the loop resistance of the transition device to such a low level, providing a more reliable and efficient solution for the operation, maintenance and testing of GIS equipment.

[0052] In summary, the setting of loop resistance less than 20 μΩ is a crucial technical indicator in the embodiment of the present invention, which further highlights the significant advantages of the present invention in improving the measurement accuracy of GIS conductor loop resistance and ensuring data reliability.

[0053] In one implementation of this embodiment, the belt body 1 is cleverly designed with a conductive portion at the other end away from the buckle 2. The conductive portion is designed to form a stable and reliable electrical connection with the loop electrical test clamp, thereby ensuring that when measuring the loop resistance of the GIS conductor, the current can smoothly pass through the transition device and be accurately captured and recorded by the test clamp.

[0054] Specifically, the conductive parts are usually made of materials with high conductivity, such as copper, silver or gold plating, to ensure good electrical contact performance and low contact resistance. At the same time, the shape and size of the conductive parts are also carefully designed and optimized to perfectly match the interface of the loop electrical test clip, thereby achieving a quick, easy and stable connection.

[0055] In addition, the connection between the conductive part and the belt body 1 also adopts advanced technical means, such as welding, crimping or threaded connection, to ensure the reliability and durability of the connection. In this way, even when performing long-term measurements or facing harsh working environments, the conductive part can always maintain a close connection with the belt body 1 without loosening or falling off.

[0056] Please refer to Figure 2 In a more in-depth and specific implementation of this embodiment, a plurality of springs 3 are innovatively arranged inside the belt body 1. The special feature of these springs 3 is that their compression direction is carefully designed to be toward the axis of the ring formed by the belt body 1 and the buckle 2.

[0057] This design brings multiple significant advantages. First, the introduction of spring 3 gives the strip 1 a certain elasticity and adaptability. When the strip 1 is wound on the surface of the GIS conductor, the spring 3 will be appropriately compressed and deformed according to the shape and size of the conductor, thereby ensuring that the strip 1 can fit tightly on the conductor surface to form a stable electrical connection. This adaptability greatly increases the contact area and contact pressure between the transition device and the GIS conductor, thereby improving the accuracy and reliability of the measurement.

[0058] Secondly, the design that the compression direction of the spring 3 is toward the axis of the ring also helps to maintain the stability of the ring structure of the belt body 1 during the measurement process. Even in the face of slight undulations or irregular shapes on the surface of the GIS conductor, the spring 3 can absorb these changes through its elastic deformation, preventing the belt body 1 from loosening or deforming during the measurement process.

[0059] In addition, the setting of the spring 3 also takes into account the convenience and comfort of the maintenance personnel during operation. Since the spring 3 has a certain elasticity, the maintenance personnel can feel a certain buffer and feedback force when winding the belt body 1, so it is easier to grasp the tightness and uniformity of the winding.

[0060] Please refer again Figure 2 In one implementation of this embodiment, the plurality of springs 3 disposed inside the belt body 1 are not randomly arranged, but are distributed at intervals. This carefully designed layout not only optimizes the stress state of the springs 3, but also further improves the overall performance of the transition device.

[0061] Specifically, the spaced distribution of the springs 3 means that there is a certain gap between them, which provides sufficient deformation space for the springs 3 when subjected to external forces. When the strip 1 is wound on the surface of the GIS conductor, each spring 3 can be independently compressed and deformed according to the shape and size of the conductor, thereby ensuring that the strip 1 can fit more evenly on the conductor surface. This distribution method avoids mutual influence and interference between the springs 3, so that each spring 3 can exert the best elastic effect.

[0062] In addition, the spacing of the springs 3 also helps to improve the durability and reliability of the transition device. Since there is a certain gap between the springs 3, even if one of the springs 3 is damaged due to long-term use or external force, it will not cause a chain reaction on the other springs 3. This design enables the transition device to maintain a more stable and lasting performance when facing a complex and changing measurement environment.

[0063] Although the terms such as belt body and buckle are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.

[0064] A GIS conductor loop resistance measurement transition device provided in an embodiment of the present invention can not only make good contact with the GIS conductor but also not damage the conductor surface. No metal foreign matter is generated during the contact process, which is convenient for operation and maintenance personnel to efficiently measure the loop resistance data of the interval. The device can be widely used in on-site GIS equipment loop resistance testing work, and is particularly suitable for confirming the condition of the main conductor after opening the cover. It has broad application prospects.

[0065] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
