Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more specifically, to a copper busbar testing fixture for gas-insulated metal-enclosed switchgear. Background Technology

[0002] In power transmission and distribution systems, gas-insulated metal-enclosed switchgear is widely used due to its advantages such as high reliability, strong anti-interference ability, and small footprint. As a key conductive component in gas-insulated metal-enclosed switchgear, the copper busbar (also known as copper busbar or copper busbar) plays a crucial role in transmitting current and connecting electrical equipment in the circuit. Its processing and installation quality directly affects the conductivity, temperature rise characteristics, and operational safety of the entire switchgear.

[0003] Currently, copper busbars used in gas-insulated metal-enclosed switchgear are mainly divided into two categories based on the form of raw materials: plate copper busbars and rod copper busbars. Gas-insulated metal-enclosed switchgear typically requires the use of various complex irregular-shaped copper busbars. Among them, plate copper busbars have a relatively simple structure and are easy to inspect, while rod copper busbars, due to their irregular structure with multiple bends, are difficult to fix on conventional testing platforms during inspection, increasing the difficulty of inspection and resulting in low inspection efficiency. Utility Model Content

[0004] This application provides a copper busbar testing fixture for gas-insulated metal-enclosed switchgear, which can quickly test copper busbars, improve copper busbar testing efficiency, and increase production efficiency.

[0005] This application provides a copper busbar testing fixture for gas-insulated metal-enclosed switchgear, comprising:

[0006] Base;

[0007] A support assembly is fixedly connected to the base. The support assembly includes two end fixing seats, at least two horizontal segment detection elements, and at least one bending segment detection element. The two end fixing seats are used to fix the two ends of the copper busbar respectively. The horizontal segment detection element is provided with a first positioning detection structure for positioning and detecting the horizontal segment of the copper busbar. The bending segment detection element is provided with a second positioning detection structure for positioning and detecting the bending segment of the copper busbar.

[0008] In some embodiments, the two end fixing seats are respectively a first end fixing seat and a second end fixing seat;

[0009] The first end fixing seat is provided with a first positioning surface and a first locking hole. The support assembly also includes a first fastener, which is used to lock the first end of the copper busbar into the first locking hole. The second end fixing seat is provided with a limit groove and a second locking hole. The limit groove is used to limit the second end of the copper busbar. The support assembly also includes a second fastener, which is used to lock the second end of the copper busbar into the second locking hole.

[0010] In some embodiments, a clamping device is also included; the base is provided with a slide rail, the bottom of the end fixing seat is provided with a slider, the slider cooperates with the slide rail, and the clamping device is used to clamp the slider and the slide rail.

[0011] In some embodiments, the end fixing seat is detachably connected to the base, the bottom of the end fixing seat is provided with a first screw, the base is provided with a first threaded hole, and the first screw is threadedly connected to the first threaded hole.

[0012] In some embodiments, a second screw is provided at the bottom of the horizontal segment detection component, and a second threaded hole is provided on the base.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 This application provides a copper busbar testing fixture for gas-insulated metal-enclosed switchgear, comprising a base 2 and a support assembly 1. The base 2 serves as the base of the copper busbar testing fixture, providing an installation foundation for the support assembly 1. It can be a plate structure with a certain thickness, a block, or a frame. The base 2 can be made of steel, alloys, or other materials with sufficient strength to ensure the overall rigidity and stability of the base 2, prevent deformation due to load, and ensure the installation accuracy of the support assembly 1. The support assembly 1 is fixedly installed on the base 2. The support assembly 1 includes two end fixing seats, which can be block-shaped, column-shaped, or bracket-shaped. The end fixing seats are provided with positioning pin holes or bolt holes, which can be aligned with the mounting holes at the ends of the copper busbar and locked in place using fasteners. The support component 1 also includes at least two horizontal segment detection elements 13 and at least one bending segment detection element 14. The horizontal segment detection element 13 is provided with a first positioning detection structure 131, which is used to position and detect the horizontal segment of the copper busbar 3. The bending segment detection element 14 is provided with a second positioning detection structure 141, which is used to position and detect the bending segment of the copper busbar 3.

[0031] The position of the end fixing seat is set according to the overall length and end position of the copper busbar 3. The end fixing seat can fix the two ends of the copper busbar 3 to form a reference for the entire inspection process. The first positioning detection structure 131 is set on the horizontal section detection piece 13. It is a precisely machined plane or a plane with a certain precision formed by a support structure. The height value of this plane is the theoretical height value of the horizontal section of the copper busbar. The positioning of the first positioning detection structure 131 provides a support point in the height direction for the horizontal section of the copper busbar. By observing whether the lower surface of the horizontal section of the copper busbar is completely in contact with the top surface of the first positioning detection structure 131, the warping, twisting or height deviation of the horizontal section can be detected.

[0032] The bending section detection component 14 is used to detect the bending or tilting part of the copper busbar 3. It is equipped with a second positioning detection structure 141, which has positioning and detection functions. It guides the copper busbar into the second positioning detection structure 141 and provides lateral support for the bending section of the copper busbar. By observing whether the lower surface of the bending section of the copper busbar is completely in contact with the top surface of the second positioning detection structure 141, the qualified component can be completely fitted with the first positioning detection structure 131 without obvious or large gaps or obvious interference. It can also be judged in conjunction with measuring rulers, detectors and other tools, thereby detecting whether the section has warping, twisting or height deviation.

[0033] When inspecting the copper busbar, the two ends of the copper busbar 3 are fixed on the two end fixing seats respectively. The first positioning and detection structure 131 provides lateral support for the horizontal section of the copper busbar 3, guides the horizontal section into the test, and limits the side of the horizontal section. At the same time, it is used to detect the bent or tilted parts of the copper busbar 3.

[0034] During the process of fixing the end, each horizontal segment of the copper busbar 3 falls directly on the first positioning detection structure 131 of the corresponding horizontal segment detection piece 13. At the same time, the bent segment of the copper busbar 3 will be embedded in the second positioning detection structure 141 of the corresponding bent segment detection piece 14. By judging the degree of fit between the horizontal segment and the bent segment of the copper busbar 3 and its corresponding positioning detection structure, the processing error of the copper busbar 3 is judged, thereby screening out qualified copper busbars 3.

[0035] The copper busbar testing fixture provided in this application for gas-insulated metal-enclosed switchgear improves the testing efficiency of the copper busbar 3, is easy to operate, and enables efficient testing of irregularly shaped copper busbars 3.

[0036] Regarding the specific structure of the two end fixing seats, in the first specific embodiment, the two end fixing seats are a first end fixing seat 11 and a second end fixing seat 12. The first end fixing seat 11 is provided with a first positioning surface 111, and the first positioning surface 111 is provided with a first locking hole. The support component 1 includes a first fastener and a second fastener. The first fastener locks the first end of the copper busbar 3 into the first locking hole. The second end fixing seat 12 is provided with a limiting groove 121 and a second locking hole 122. The limiting groove 121 is used to limit the second end of the copper busbar, and the second fastener is used to lock the second end of the copper busbar into the second locking hole 122. This allows for the positioning and locking of a copper busbar with one flat end and one vertical end.

[0037] In the second specific embodiment, both the first end fixing seat 11 and the second end fixing seat 12 are provided with positioning surfaces. Locking holes are formed on the positioning surfaces, and locking components are used to fix the end to the positioning surfaces and lock it within the locking holes, thereby achieving the positioning of the end. In this embodiment, the positioning and locking of copper busbars 3, which have flat ends at both ends, can be achieved.

[0038] In the third specific embodiment, both the first end fixing seat 11 and the second end fixing seat 12 are provided with a limiting groove 121 and a locking hole. The copper busbar end is installed in the limiting groove 121 and locked and fixed by a locking member. In this embodiment, the positioning and locking of copper busbars with both ends being vertical can be satisfied.

[0039] The above three embodiments can satisfy the fixing of different combination types of ends.

[0040] Optionally, the second positioning and detection structure 141 is specifically a U-shaped groove with an inclined surface. The U-shaped groove is used to position the side wall of the bent section of the copper busbar, and the inclined surface is used as a reference surface to detect the processing accuracy of the bent section of the copper busbar. The structure is simple and easy to process.

[0041] To further enhance the versatility of the tooling and enable it to adapt to various types of copper busbar inspection, in a preferred embodiment, a slide rail is provided on the upper surface of the base 2. This slide rail is preferably a T-slot or dovetail groove type, extending along the length of the base 2. Slider blocks matching the shape of the slide rail are fixedly installed at the bottom of the two end fixing seats. The sliders are embedded in the slide rail, allowing the end fixing seats to slide freely along the length of the slide rail, thereby adjusting the distance between the two end fixing seats.

[0042] To ensure the end fixing seat is firmly fixed after adjustment, a clamping device can be further installed to tightly fix the slider and the slide rail together, eliminating the gap between them and preventing movement during the testing process.

[0043] Optionally, the clamping device may include a T-bolt and a lock nut. The T-bolt passes through the end fixing seat or the slider, and rotating the lock nut engages with the T-bolt to press the slider against the side wall of the slide. Alternatively, a clamping handle may be used to achieve faster operating speeds.

[0044] When it is necessary to test copper busbars of different lengths 3, the operator first loosens the clamping device, then slides the two end fixing seats along the slide to the corresponding preset position according to the hole spacing of the copper busbar to be tested, and finally tightens the clamping device to securely lock the end fixing seats for subsequent testing operations.

[0045] To adjust the reference height of the end-mount fixing seat, in one specific embodiment, a first screw is provided at the bottom of the end-mount fixing seat, and a first threaded hole is provided on the base 2. The first screw is threadedly connected to the first threaded hole, thereby adjusting the height of the end-mount fixing seat to accommodate copper busbars of different heights. Furthermore, the end-mount fixing seat can also achieve height adjustment through the engagement of the inclined surfaces of two vertically distributed wedge-shaped blocks.

[0046] Furthermore, a second screw is provided at the bottom of the horizontal section detection component 13, and a second threaded hole is provided on the base 2. The second screw is threadedly connected to the second threaded hole. By rotating the end fixing seat, the height of the horizontal section detection component 13 relative to the base 2 can be adjusted through the transmission of the threaded pair between the second screw and the second threaded hole. After the height is adjusted to the correct position, the locking nut is tightened to lock and fix the height.

[0047] In addition, a third screw is provided at the bottom of the bending section detection piece 14, and a third threaded hole is provided at the base 2. The third screw is threadedly connected to the third threaded hole to adjust the height of the bending section detection piece 14.

[0048] To facilitate adjustment of the support height of the support assembly 1, adjustment shims can be further provided. The adjustment shims can be set at the top or bottom of the end fixing seat, the horizontal section detection component 13, and the bending section detection component 14, and can be fixedly connected by locking or magnetic attraction to adjust the support height and meet the measurement requirements of different models of copper busbars 3.

[0049] To improve the accuracy of leveling the copper busbar 3, a leveling detection device can be used. The leveling detection device is a bubble level or an electronic level sensor. The leveling detection device is set on the base 2 or the support and is used to detect the leveling of the copper busbar after installation.

[0050] The foregoing has provided a detailed description of the copper busbar testing fixture for gas-insulated metal-enclosed switchgear provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
