[0019] Additional aspects and advantages of this application will become apparent in the following description or may be learned by practice of this application. Attached Figure Description

[0020] The above and / or additional aspects and advantages of this application will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0021] Figure 1 This invention provides a schematic diagram of the structure of a switchgear test plug installation fixture in one embodiment of the present application.

[0022] in, Figure 1 The correspondence between the reference numerals and component names in the attached drawings is as follows:

[0023] 100 Support beam, 102 First sliding hole, 104 Second sliding hole, 106 Threaded hole, 110 First positioning post, 112 First magnetic component, 120 Second positioning post, 122 Second magnetic component, 130 Adjusting screw, 140 Circular pressure plate, 150 Handle, 152 Main rod, 154 Telescopic rod. Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0026] The following reference Figure 1 This application describes a switchgear test plug installation fixture according to some embodiments.

[0027] like Figure 1 As shown, this application provides a test plug installation fixture for a switchgear, comprising: a support beam 100, on which a first sliding hole 102, a second sliding hole 104, and a threaded hole 106 are provided, the threaded hole 106 being located between the first sliding hole 102 and the second sliding hole 104; a first positioning post 110 slidably passing through the first sliding hole 102, one end of the first positioning post 110 being provided with a first magnetic element 112; a second positioning post 120 slidably passing through the second sliding hole 104, one end of the second positioning post 120 being provided with a second magnetic element 122; and an adjusting screw 130 threadedly engaging with the threaded hole 106; wherein, the first magnetic element 112 and the second magnetic element 122 are used to fix the installation fixture to the switchgear, the first end of the adjusting screw 130 is used to abut against the test plug, and the test plug is pressed into the installation position by rotating the adjusting screw 130.

[0028] The switchgear test plug installation fixture provided in this application includes a support beam 100, a first positioning post 110, a first magnetic component 112, a second positioning post 120, a second magnetic component 122, and an adjusting screw 130. The first positioning post 110 and the second positioning post 120 slide within the first sliding hole 102 and the second sliding hole 104, respectively. The first magnetic component 112 and the second magnetic component 122 are respectively located at the same end of the first positioning post 110 and the second positioning post 120. By setting the first magnetic component 112 and the second magnetic component 122, a reliable fixing method can be provided for the fixture. After the plug is fixed to the switchgear cable hole, the strong adsorption force of the magnetic component allows the fixture to be tightly adsorbed onto the bottom of the switchgear, effectively preventing displacement or shaking of the fixture due to external forces during installation, ensuring the stability and accuracy of the test plug installation, and improving the installation quality. After the test plug is installed, the first positioning post 110 and the second positioning post 120 can be moved outward to separate the first magnetic component 112 and the second magnetic component 122 from the switch cabinet, which facilitates the subsequent installation of other test plugs.

[0029] When installing the test plug, simply rotate the adjusting screw 130. Utilizing the threaded engagement between the adjusting screw 130 and the threaded hole 106, the first end of the adjusting screw 130 gradually approaches and abuts against the test plug, thus pressing the plug into the installation position. The entire operation is simple and easy to understand, requiring no complex operating skills or professional knowledge, reducing the technical requirements for operators and facilitating quick mastery by on-site construction personnel.

[0030] Using the switchgear test plug installation fixture provided in this application, on-site construction personnel can easily install the test plugs in place, saving labor and time costs. This reduces downtime or overall test duration, improving work efficiency. After implementing the new solution, the installation of test plugs is convenient and quick, significantly reducing the likelihood of improper installation, and even novices can operate it directly.

[0031] By using the switchgear test plug installation fixture provided in this application, it is possible to achieve the goals of saving time and effort and facilitating operation, while also greatly shortening the test time.

[0032] like Figure 1 As shown, in some embodiments provided in this application, the first end of the adjusting screw 130 is provided with a circular pressure plate 140.

[0033] In this embodiment, by setting a circular pressure plate 140 at the first end of the adjusting screw 130, the contact area between the adjusting screw 130 and the test plug can be increased, so that the pressure is more evenly distributed on the surface of the test plug, avoiding excessive local pressure, reducing the risk of damage to the plug or switch cabinet cable hole due to local stress, ensuring installation quality, and also adapting to plugs of different shapes, thus improving the versatility of the tooling.

[0034] The circular pressure plate 140 reduces wear caused by direct contact between the adjusting screw 130 and the test plug, extending their service life. The circular pressure plate 140 also ensures smoother contact between the adjusting screw 130 and the test plug, reducing shaking and jamming during rotation and making the installation process smoother and more efficient.

[0035] In some embodiments provided in this application, the surface of the circular pressure plate 140 is provided with a cushioning pad.

[0036] In this embodiment, by setting a buffer pad on the surface of the circular pressure plate 140, the pressure can be further dispersed, making the force acting on the test plug more uniform, avoiding local stress concentration, preventing the plug from deforming or being damaged due to uneven force, and ensuring installation quality.

[0037] The buffer pad absorbs the impact force generated when the adjusting screw 130 rotates and applies pressure, thus playing a shock-absorbing and buffering role and reducing the vibration impact on related components of the switchgear. At the same time, the buffer pad also protects the surface of the circular pressure plate 140 and the plug, reducing wear caused by direct contact friction and extending the service life of the circular pressure plate 140 and the test plug.

[0038] In some embodiments provided in this application, the buffer pad is a rubber pad, which is fixed to the surface of the circular pressure plate 140 by adhesive or snap-fit.

[0039] In this embodiment, the rubber pad has good elasticity. By using a rubber pad as the buffer and fixing it to the surface of the circular pressure plate 140 through bonding or snap-fitting, it can further buffer the impact force when the adjusting screw 130 applies pressure, effectively protecting the test plug and related components of the switch cabinet, and reducing damage caused by pressure. The bonding or snap-fitting method is simple and reliable. Bonding ensures a tight fit between the rubber pad and the pressure plate, preventing loosening; snap-fitting facilitates replacement, allowing for quick replacement when the rubber pad wears out.

[0040] like Figure 1 As shown, in some embodiments provided in this application, the other end of the adjusting screw 130 is provided with a handle 150.

[0041] In this embodiment, the other end of the adjusting screw 130 is provided with a handle 150. The handle 150 provides a point of leverage for the operator, allowing for easy rotation of the adjusting screw 130 by simply holding the handle 150 without the need for additional tools, thus accelerating the installation process of the test plug. The operator can more stably control the rotation force and speed, precisely adjust the pressure on the test plug, and ensure installation quality.

[0042] like Figure 1As shown, in some embodiments provided in this application, the handle 150 is a telescopic handle, which includes a main rod 152 and a telescopic rod 154. The main rod 152 is connected to the adjusting screw 130, and the telescopic rod 154 can extend and retract along the length direction of the main rod 152.

[0043] In this embodiment, the handle 150 is a telescopic handle, which includes a main rod 152 and a telescopic rod 154. By providing the telescopic rod 154, the length of the handle 150 can be adjusted, enhancing the operating space and adaptability. During transportation and storage, the telescopic rod 154 can be retracted to reduce the overall length of the handle 150 and save space; when in use, the telescopic rod 154 can be pulled out to meet the requirements of operating distance and effort reduction.

[0044] In addition, the retractable handle improves the stability and controllability of operation. Operators can precisely control the rotation force and speed of the adjusting screw 130 according to actual needs to ensure that the test plug is pressed into the installation position smoothly and accurately, thus ensuring the installation quality of the switchgear test plug.

[0045] In some embodiments provided in this application, the first magnetic element 112 and the second magnetic element 122 are neodymium iron boron permanent magnets.

[0046] In this embodiment, the first magnetic component 112 and the second magnetic component 122 are neodymium iron boron permanent magnets. Neodymium iron boron permanent magnets have excellent magnetic properties and strong magnetism, which can generate a strong attraction force, making the installation fixture more firmly attached to the switch cabinet, effectively preventing the fixture from shifting during installation and ensuring the accuracy of the test plug installation.

[0047] In some embodiments provided in this application, the first magnetic element 112 is detachably connected to the first positioning post 110, and the second magnetic element 122 is detachably connected to the second positioning post 120.

[0048] In this embodiment, the first magnetic component 112 is detachably connected to the first positioning post 110, and the second magnetic component 122 is detachably connected to the second positioning post 120. Magnetic components of different specifications or magnetic forces can be quickly replaced according to the installation environment requirements, enhancing the compatibility of the installation fixture with different scenarios.

[0049] If the magnetic components deteriorate or become damaged due to prolonged use, they can be replaced individually without discarding the entire positioning column, extending the tooling's lifespan and reducing operating costs. The detachable design facilitates cleaning, maintenance, and magnetic calibration of the magnetic components, ensuring adsorption stability.

[0050] In some embodiments provided in this application, the outer sides of the first magnetic element 112 and the second magnetic element 122 are provided with rubber protective sleeves.

[0051] In this embodiment, a rubber protective sleeve covers the outer surfaces of the first magnetic component 112 and the second magnetic component 122, preventing them from directly contacting the metal panel of the switchgear and thus preventing scratches on the cabinet coating or abnormal metal friction noises during installation or disassembly. This is particularly suitable for precision switchgear with high surface treatment requirements. Upon magnetic adsorption, the rubber sleeve absorbs the impact energy, reducing the probability of breakage due to instantaneous impact.

[0052] The rubber protective sleeve provides a soft touch, preventing operators from being scratched by the sharp edges of magnetic parts, while also reducing metal-on-metal collision noise when installing and removing tooling.

[0053] In some embodiments provided in this application, the first positioning post 110 and the second positioning post 120 are stud structures, and the first sliding hole 102 and the second sliding hole 104 are screw holes adapted to the stud structure.

[0054] In this embodiment, the threaded engagement provides a self-locking function, avoiding the axial movement problem of traditional sliding hole structures. The interlocking structure between the stud and the threaded hole significantly improves shear resistance, effectively resisting lateral forces when the test plug is pressed down by the adjusting screw 130. The extension length can be changed by rotating the stud, expanding the application scenarios of the installation fixture.

[0055] In a specific embodiment, the switchgear test plug installation fixture provided in this application is used for SF6 fully insulated switchgear, which can efficiently and conveniently complete the installation of test plugs for SF6 fully insulated switchgear. It solves the problems of time-consuming and labor-intensive installation of test plugs and the possibility of improper installation in related technologies. Using the switchgear test plug installation fixture provided in this application, the installation of test plugs is convenient, fast, and accurate.

[0056] like Figure 1 As shown, the overall structure of the switchgear test plug installation fixture includes a support beam 100, two positioning posts (first positioning post 110 and second positioning post 120), and an adjusting screw 130 (one end of the adjusting screw 130 is equipped with a circular pressure plate 140, the surface of which is covered with a rubber pad; the other end of the adjusting screw 130 is equipped with an operating handle). Strong magnets are installed on the two positioning posts. Specifically, after the test plug is fixed to the switchgear cable hole, it is attracted to the bottom of the switchgear by the strong magnet for fixation. The test plug is then pressed into the cable hole by rotating the adjusting screw 130 in the middle of the support beam 100. The installation process is convenient and quick, greatly reducing the possibility of improper installation, and even beginners can operate it directly.
