DETAILED DESCRIPTION

[0018] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] Please refer to Figure 1-5 A high-voltage switch mechanical characteristic test bench comprises a test bench body 1 and a high-voltage switch installed in the test bench body 1, wherein the test bench body 1 comprises a bottom frame 2 and columns 4, wherein a bottom panel 3 is arranged in the bottom frame 2, wherein the columns 4 are fixed at the corners of the bottom frame 2 and extend vertically upward, wherein there are four columns 4, wherein an intermediate beam 5 and a top beam 6 are arranged between the bottom frames 2, wherein the heights of the intermediate beam 5 and the top beam 6 can be adjusted between the two columns 4; that is, the distance between the intermediate beam 5 and the top beam 6 can be adjusted, and high-voltage switches of different sizes and models can be installed during the test, which is convenient for the test and detection, wherein a first side plate 7 is arranged on the outer side of two columns 4, and a second side plate 8 is arranged on the outer side of the other two columns 4, wherein a plurality of first assembly holes 31 are evenly arranged around the bottom panel 3, wherein the columns 4 can be installed at any of the first assembly holes 31; that is, the distance between the two columns 4 can be adjusted, and high-voltage switches of different sizes and models can also be installed, thereby increasing the applicable scope of the test bench.

[0020] In the present invention, the bottom frame 2, the columns 4, the middle cross beam 5 and the top cross beam 6 are all square tubes of aluminum alloy profiles; assembly grooves are provided on the four surrounding surfaces for easy bolting, which will not be described in detail here.

[0021] Specifically, an L-shaped corner 11 is provided at the connection between the bottom frame 2, the column 4, the middle beam 5 and the top beam 6, and high-strength bolts 12 are provided at both ends of the L-shaped corner 11. The L-shaped corner 11 and the high-strength bolts 12 cooperate to connect adjacent square tubes.

[0022] When in use, the L-shaped corner 11 is placed at the corner connection so that the two high-strength bolts 12 correspond to the assembly grooves on the side of the square tube. After the high-strength bolts 12 are tightened, the two square tubes in different directions are connected, thereby increasing the overall stability.

[0023] In addition, since the calibration bench body is bolted with square tubes, it is easy to install and disassemble. At the same time, the size of the calibration bench body can be adjusted according to needs, thereby increasing the scope of application of high-voltage switch calibration.

[0025] As a preferred solution, a connecting plate 10 is provided at the end of the top crossbeam 6, and the connecting plate 10 includes an L-shaped connecting plate 101 and an extension plate 102. One end of the L-shaped connecting plate 101 is detachably connected to the top crossbeam 6, and the other end is formed integrally with the extension plate 102. The L-shaped connecting plate 101 is perpendicular to the extension plate 102. The second side plate 8 is connected between the two extension plates 102. The extension plate 102 is provided with multiple layers of third assembly holes 103. The second side plate 8 can cooperate with any layer of the third assembly holes 103, and the height of the second side plate can be adjusted. The structure is more reasonable and easy to use.

[0026] In this embodiment, the verification station is mainly used to verify the opening and closing actions of the high-voltage switch, and can also be used to verify the opening and closing actions of the circuit breaker.

[0027] In addition, the appearance of the high-voltage switch can be checked to see if the surface is cracked or worn to ensure its quality.
