Therefore, during testing of the pole-mounted circuit breaker, its position will not shift, ensuring the stable connection between the pole-mounted circuit breaker and the testing device, improving the accuracy of the test results, making accurate quality judgments on the pole-mounted circuit breaker, and improving safety. Furthermore, the mounting unit 30 is connected to the drive assembly 40, which drives the mounting unit 30 to rotate. Thus, during the testing of the pole-mounted circuit breaker, the mounting unit 30 can drive the pole-mounted circuit breaker to rotate, thereby completing the testing of different functions of the pole-mounted circuit breaker, which has good applicability.
[0024] It should be noted that during the process of performing different functional tests on the pole-mounted circuit breaker, after completing a certain functional test, the installation unit 30 drives the pole-mounted circuit breaker to rotate before performing another functional test. During the same functional test, the pole-mounted circuit breaker remains stationary.
[0025] In some embodiments, please refer to Figure 1 and Figure 2 The installation unit 30 includes mounting components 31 and locking components. Multiple mounting components 31 are arranged at intervals, and each mounting component 31 has multiple mounting holes 313. Multiple locking components are also included, each corresponding to one of the mounting holes 313. Each locking component is used to lock the pole-mounted circuit breaker onto the two mounting components 31, and each locking component is detachably connected to the pole-mounted circuit breaker. In this embodiment, multiple mounting holes 313 are provided on the mounting components 31, and multiple locking components are provided corresponding to each mounting hole 313. The pole-mounted circuit breaker is installed on the mounting component 31 through each locking component, ensuring the stability of the installation. Furthermore, the detachable connection between each locking component and the pole-mounted circuit breaker facilitates the installation and removal of the pole-mounted circuit breaker, making operation convenient.
[0026] In some embodiments, please refer to Figure 1 and Figure 2 The spacing direction between the two mounting components 31 is defined as the first direction. The base frame 10 includes a bottom fixing structure 11 and column assemblies 12.

The drive assembly 40 is mounted on the top of the two sets of column assemblies 12 and connected to the mounting unit 30, thus placing the mounting unit 30 above the support assembly 20. Placing the pole-mounted circuit breaker on the support assembly 20 and then installing it onto the mounting unit 30 reduces the workload of the operator.
[0027] In some embodiments, please refer to Figure 1 The horizontal direction perpendicular to the first direction is defined as the second direction, and each column assembly 12 includes two vertical rods 121 spaced apart along the second direction.
[0028] In some embodiments, please refer to Figure 1 The bottom fixing structure 11 includes a base plate 111, a transverse connecting beam 112, and a longitudinal connecting beam 113. Two base plates 111 are provided, spaced apart along a first direction.

The bottom end of each vertical rod 121 is connected to the corresponding transverse connecting beam 112. Two longitudinal connecting beams 113 are provided, arranged along the first direction and spaced apart along the second direction, with both ends of each longitudinal connecting beam 113 connected to the two transverse connecting beams 112.
[0029] In some embodiments, please refer to Figure 1 and Figure 2 The base frame 10 also includes multiple reinforcing plates 50, each reinforcing plate 50 being disposed at the connection end between the two sets of column assemblies 12 and the bottom fixing structure 11. In this embodiment, reinforcing plates 50 are disposed at the connection end between the two sets of column assemblies 12 and the bottom fixing structure 11, thereby enhancing the connection strength between the column assemblies 12 and the bottom fixing structure 11 and improving the stability of the base frame 10.
[0030] In some embodiments, please refer to Figure 1 and Figure 2The drive assembly 40 includes a drive motor 41 and a rotating shaft 42. The drive motor 41 is located at the top of one set of column assemblies 12, and its power output end is connected to one of the mounting members 31. The rotating shaft 42 is rotatably located at the top of another set of column assemblies 12, and is connected to another mounting member 31.
[0031] Specifically, the base frame 10 also includes a motor mounting base 13 and a bearing housing 14. The motor mounting base 13 is located at the top of one set of column assemblies 12, and the bearing housing 14 is located at the top of another set of column assemblies 12. The drive motor 41 is mounted on the motor mounting base 13, and one end of the shaft 42 is connected to the mounting component 31, while the other end is provided with a bearing, which is mounted on the bearing housing 14.
[0032] In this embodiment, the power output end of the drive motor 41 is connected to one of the mounting parts 31, and the rotating shaft 42 is connected to the other mounting part 31, so that the drive motor 41 drives the mounting part 31 to rotate, and the mounting part 31 drives the pole-mounted circuit breaker to rotate.
[0033] In some embodiments, please refer to Figures 1 to 3 Each mounting component 31 includes an auxiliary connecting plate 311 and a mounting plate 312. The auxiliary connecting plate 311 is connected to the power output end of the drive motor 41 or the rotating shaft 42, and is parallel and spaced apart from the corresponding column assembly 12. The mounting plate 312 is connected to the auxiliary connecting plate 311. Mounting holes 313 are provided on the mounting plate 312. In this embodiment, the auxiliary connecting plate 311 is connected to the power output end of the drive motor 41 or the rotating shaft 42, and is parallel and spaced apart from the corresponding column assembly 12, thereby ensuring that the drive motor 41 drives the auxiliary connecting plate 311 to rotate stably. The mounting plate 312 is connected to the auxiliary connecting plate 311, and mounting holes 313 are provided on the mounting plate 312. The auxiliary connecting plate 311 drives the mounting plate 312 and the pole-mounted circuit breaker to rotate. Specifically, the included angle between the mounting plate 312 and the auxiliary connecting plate 311 is 90°.
[0034] In some embodiments, please refer to Figure 1 and Figure 4The assembly and testing fixture for pole-mounted circuit breakers provided in this embodiment of the invention also includes two auxiliary support structures 60, which are correspondingly arranged with two auxiliary connecting plates 311. Each auxiliary support structure 60 includes a support plate 61, a connecting column 63, and a connecting rod 62. The support plate 61 abuts against the corresponding auxiliary connecting plate 311. There are two connecting columns 63, which are spaced apart along a second direction. One end of each connecting column 63 is connected to the support plate 61, and the other end is connected to the corresponding vertical rod 121. There are two connecting rods 62, which are located between the two connecting columns 63. One end of each connecting rod 62 is connected to the support plate 61, and the other end is connected to the two connecting columns 63 respectively. Each connecting rod 62 is arranged at an angle to the support plate 61. In this embodiment, one end of the connecting column 63 is connected to the support plate 61, and the other end is connected to the vertical rod 121. One end of the connecting rod 62 is connected to the support plate 61, and the other end is connected to the connecting column 63. Thus, the support plate 61, the connecting column 63, and the connecting rod 62 form a triangular structure. Simultaneously, the support plate 61 abuts against the corresponding auxiliary connecting plate 311, providing support for the auxiliary connecting plate 311. This prevents the auxiliary connecting plate 311 from shaking during the installation of the pole-mounted circuit breaker, ensuring the installation stability and accuracy of the pole-mounted circuit breaker. Specifically, the included angle between each connecting rod 62 and the support plate 61 is an acute angle. Each auxiliary support structure 60 includes two triangular structures.
[0035] In some embodiments, please refer to Figure 1 and Figure 2 The support assembly 20 includes multiple telescopic structures 22, each with a fixed end and a telescopic end. Each fixed end is connected to the bottom fixed structure 11, and each telescopic end is connected to the support plate 21. In this embodiment, the fixed end of each telescopic structure 22 is connected to the bottom fixed structure 11, and each telescopic end is connected to the support plate 21, allowing the telescopic structure 22 to drive the support plate 21 to move vertically. First, the support plate 21 is lowered to its lowest position, and the pole-mounted circuit breaker is placed on it. Then, the telescopic structure 22 drives the support plate 21 upward until the pole-mounted circuit breaker abuts against the mounting plate 312, thus installing the pole-mounted circuit breaker on the mounting plate 312. This method is convenient and reduces labor intensity. During the testing of the pole-mounted circuit breaker, the position of the support plate 21 can be lowered as needed.
[0036] Specifically, the telescopic structure 22 can be a hydraulic cylinder. The fixed ends of each telescopic structure 22 are respectively set on two longitudinal connecting beams 113. The pole-mounted circuit breaker in this embodiment of the present invention is a pole-mounted circuit breaker ZW32.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
