[0061] See also Figure 1 、 Figure 2 、 Figure 3 The base 1 is used to install and support other components of the test tooling, and it can be a plate-like structure or a frame structure. The isolation module 2 is mainly used to provide electrical isolation between the test equipment and other power system components, so as to ensure that the test equipment and other equipment in the power system will not be electrically connected when conducting high-voltage tests, thereby protecting the safety of test personnel and equipment. The isolation module 2 can be an isolating switch, a grounding switch or other forms of isolation devices. The circuit breaker module 3 is mainly used to provide a controllable circuit breaker point in the circuit so that the current can be cut off when needed; when conducting a high-voltage test, the circuit breaker module 3 can quickly cut off the current during the test or when the test fails, protecting the test equipment and personnel. The bushing module 4 generally refers to the insulating bushing in high-voltage electrical equipment, which mainly provides insulation support for the conductor and allows current to pass through; when conducting a high-voltage test, the bushing module 4 is used to simulate the insulation conditions in actual operation, or as part of the test, to test the insulation performance of the bushing itself.

[0062] See also Figure 1 、 Figure 2 、 Figure 3 , the isolation module 2, the circuit breaker module 3 and the bushing module 4 adopt a modular design; the isolation module 2 is arranged above the base 1 and is detachably connected to the base 1, so that the base 1 is used to install and support the isolation module 2, and the circuit breaker module 3 and the bushing module 4 are respectively arranged on both sides of the isolation module 2 and are detachably connected to the isolation module 2, so that the isolation module 2 is used to install and support the circuit breaker module 3 and the bushing module 4. Exemplarily, the bushing module 4 may include three bushings. Since the bushing module 4 is heavy, in order to improve the reliability and safety of the bushing module 4 after installation, a lifting device 5 connected to the base 1 is provided below the bushing module 4; when performing a high-voltage test, the lifting device 5 can be controlled so that the top of the lifting device 5 contacts the bushing module 4, and the lifting device 5 is used to provide auxiliary support for the bushing module 4.

[0063] The high-voltage electrical equipment test fixture provided in the embodiment of the present application can utilize the cooperation of the isolation module 2, the circuit breaker module 3 and the bushing module 4 to perform high-voltage tests on GIS and GIL equipment; the modular design makes the installation and disassembly of the isolation module 2, the circuit breaker module 3 and the bushing module 4 more flexible and convenient; when performing high-voltage tests on GIS and GIL equipment of different specifications and configurations, it is only necessary to select the corresponding models of isolation modules 2, circuit breaker modules 3 and bushing modules 4 for quick assembly, without the need to redesign and manufacture the test fixture, and even more without the need to perform a large amount of disassembly and modification of the GIS and GIL equipment; compared with traditional test fixtures, the test cycle is shortened, the test cost is reduced, and the risk of damage to GIS and GIL equipment is reduced.

[0064] The high-voltage electrical equipment test fixture provided in the embodiment of the present application is provided with a lifting device 5, which is not only used to support the bushing module 4 with a heavier weight, so as to better control the stress state of the bushing module 4, reduce deformation caused by its own weight or external force, and improve the reliability and safety of the entire test fixture, but also can support bushing modules 4 of different sizes to adapt to different structural designs and test requirements.

[0065] The lifting device 5 may include a linear drive such as a pneumatic cylinder, a hydraulic cylinder or an electric push rod, or may include a screw lifting device or a chain lifting device.

[0066] In some embodiments, see Figure 2 The lifting device 5 includes a fixed base 51 connected to the base 1, a support base 52 movably connected to the fixed base 51 and used to support the cannula module 4, and a lifting mechanism connected between the fixed base 51 and the support base 52 and used to drive the support base 52 to move up and down. During use, the lifting mechanism drives the support base 52 to move up and down to adjust the height of the support base 52 as needed; when the support base 52 contacts the bottom of the cannula module 4, the cannula module 4 is supported by the support base 52.

[0067] In some embodiments, see Figure 2 、 Figure 3 The fixing base 51 is provided with a vertically extending slot 511, within which a sliding block is disposed for sliding engagement. The supporting base 52 is connected to the sliding block. The design of the slot 511 and the sliding block not only facilitates assembly, maintenance, and replacement, but also reduces friction and wear during sliding, extending service life and providing a smoother sliding experience.

[0068] For example, see Figure 3The fixed base 51 includes a horizontally arranged pad 512 and two vertically arranged fixed plates 513. The pad 512 is connected to the base 1. The two fixed plates 513 are arranged opposite each other and connected to the pad 512 at their lower ends. The inner surfaces of the two fixed plates 513 are each provided with a slide groove 511, and the cross-section of the slide groove 511 is roughly T-shaped. The support base 52 includes a horizontally arranged support plate 521, which is arranged between the two fixed plates 513. The opposite ends of the support plate 521 are connected to sliders, which slide in the slide grooves 511.

[0069] The lifting mechanism is used to drive the support base 52 to move up and down, and it can include a cylinder, a hydraulic cylinder or an electric push rod. Figure 2 The lifting mechanism includes a threaded rod 53 disposed horizontally below the support base 52 and rotatably connected to the fixed base 51, a motor 54 disposed on the fixed base 51 and used to drive the threaded rod 53 to rotate about its own axis, a movable block 55 threadedly connected to the threaded rod 53, and a connecting rod 56 hinged between the movable block 55 and the support base 52. During use, the motor 54 drives the threaded rod 53 to rotate, which in turn drives the movable block 55 on it to move along its axial direction. The movable block 55 drives the connecting rod 56 to lift the support base 52, thereby adjusting the height of the support base 52.

[0070] In some embodiments, see Figure 2 The ends of the threaded rod 53 are rotatably connected to the fixed base 51. The threaded rod 53 has two externally threaded sections that rotate in opposite directions. The movable blocks 55 are respectively threadedly connected to the two externally threaded sections. During use, the motor 54 drives the threaded rod 53 to rotate, which drives the two movable blocks 55 on it toward or away from each other. The movable blocks 55 drive the connecting rod 56 to lift the support base 52, thereby adjusting the height of the support base 52.

[0071] For example, see Figure 2 、 Figure 3 The threaded rod 53 is disposed between the two fixed plates 513. The ends of the threaded rod 53 are rotatably connected to the two fixed plates 513 via bearings. The motor 54 is mounted on one of the fixed plates 513 and is in transmission connection with the threaded rod 53. The motor 54 and the threaded rod 53 can be directly connected, gear-driven, chain-driven, or belt-driven. Each movable block 55 can be connected to the bottom of the support plate 521 via at least one connecting rod 56.

[0072] In some embodiments, see Figure 3 A mounting plate 21 is fixed to the bottom of the isolation module 2. The mounting plate 21 is horizontally placed on the top of the base 1 and is fixedly connected to the base 1 by screws 22. Exemplarily, the screws 22 include four, and the four screws 22 are evenly distributed along the circumference of the isolation module 2.

[0073] In some embodiments, see Figure 1 , an extension piece 6 is detachably connected between the isolation module 2 and the sleeve module 4. When in use, by replacing the extension piece 6 of different sizes, the distance between the isolation module 2 and the sleeve module 4 can be adjusted to adapt to different structural designs and test requirements.

[0074] The extension piece 6 can be connected to the isolation module 2 and the casing module 4 respectively through quick-plug connectors, and the isolation module 2 and the circuit breaker module 3 can also be connected through quick-plug connectors. In some embodiments, the extension piece 6 is flange-connected to the isolation module 2 and the casing module 4 respectively, and the isolation module 2 is flange-connected to the circuit breaker module 3.

[0075] For example, see Figure 1 、 Figure 4 The isolation module 2 and the circuit breaker module 3 are detachably connected via a flange structure 8. The flange structure 8 comprises a first flange 81 connected to the isolation module 2, a second flange 82 connected to the circuit breaker module 3, several studs 83 passing through the first and second flanges 81, 82, and nuts 84 connected to the ends of the studs 83. To enhance the tightening effect of the nuts 84, a gasket 85 is provided on the side of the nut 84 facing the flange, which fits over the studs 83.

[0076] In some embodiments, see Figure 1 An operation box 7 is connected to the top of the base 1, and the operation box 7 has a display screen 71 and operation buttons 72. The display screen 71 and operation buttons 72 provide an intuitive user interface, allowing the operator to conveniently monitor the test process and results, and perform necessary operational controls.

[0077] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 The base 1 includes a horizontally arranged bottom plate 11 and casters 12 connected to the bottom plate 11. The bottom plate 11 is used to install and support other components of the test tooling. The casters 12 are used to support and move the bottom plate 11. Exemplarily, the bottom plate 11 is rectangular, and casters 12 are respectively installed at its four corners; wherein, the casters 12 can be universal wheels or fixed wheels. The provision of the casters 12 enables the test tooling to be easily moved, thereby adapting to different test sites and environments, and improving the flexibility and adaptability of the test tooling.

[0078] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3A handle 13 is connected to the base plate 11. The handle 13 provides a convenient gripping point, allowing the operator to more easily move the base plate and the structure thereon. For example, an anti-slip cover 14 is provided on the handle 13. The anti-slip cover 14 provides a better grip and friction, preventing slipping.
