Please refer to Figure 5 , in some embodiments of the present application, the operating mechanism of the leakage circuit breaker further includes a positioning plate 5.

The positioning plate 5 provides a position indication for the installation of the leakage circuit breaker A. When installing the leakage circuit breaker A, the leakage circuit breaker A can be set close to the positioning plate 5. In this way, the accuracy of the installation position of the leakage circuit breaker A can be improved.
[0064] In addition, in some embodiments of the present application, the position information of the positioning plate 5 can be stored in the control system. The control system can determine the position information of the leakage circuit breaker A according to the position information of the positioning plate 5, so as to facilitate the control system to control the three-dimensional moving platform 3 and the manipulator 4 to operate the operating part of the leakage circuit breaker A.
[0065] Please continue to refer to Figure 5, in some embodiments of the present application, the fixing structure 2 is a guide rail, and the guide rail extends along the X direction.
[0066] Please refer to Figure 4 and Figure 5 , in some embodiments of the present application, the leakage circuit breaker A is provided with a guide rail installation groove. The fixing structure 2 of the present application is a guide rail, so that the installation of the leakage circuit breaker A can be facilitated.
[0067] Please continue to refer to Figure 2 , in some embodiments of the present application, the circuit breaker testing device further includes a blocking structure 6. The blocking structure 6 is located above the closing position of the leakage circuit breaker A and is used to prevent the leakage circuit breaker A from disengaging from the guide rail when it is closed.
[0068] Please refer to Figure 2 and Figure 5 , as described above, in some embodiments of the present application, the leakage circuit breaker A is provided with a guide rail installation groove A1. The fixing structure 2 is a guide rail, and the leakage circuit breaker A can be installed on the guide rail through the guide rail installation groove A1 it has. During the test, it is necessary to perform a closing operation on the leakage circuit breaker A. The leakage circuit breaker A may generate an upward displacement due to the closing force, resulting in the phenomenon of disengaging from the guide rail.
[0069] By providing the blocking structure 6 above the closing position of the leakage circuit breaker A in the present application, the leakage circuit breaker A can be prevented from disengaging from the guide rail when it is closed, which helps the smooth progress of the test.
[0070] Please continue to refer to Figure 1 , in some embodiments of the present application, the blocking structure 6 includes a bar 61 and a bar mounting plate 62. The bar mounting plate 62 is located on one side of the fixing structure 2 in the X direction, and the bar mounting plate 62 is disposed opposite to the positioning plate 5.
[0071] One end of the bar 61 is rotatably connected to the bar mounting plate 62, and the other end of the bar 61 can be detachably connected to one or more positioning plates 5 along the X direction.
[0072] Please refer to Figure 2 and Figure 5 , in some embodiments of the present application, there are multiple guide rails, and the number of positioning plates 5 is the same as that of the guide rails. The bar 61 can be detachably connected to each positioning plate 5, so that the installation of the bar 61 can be strengthened.

One end of the blocking bar 61 is rotatably connected to the blocking bar mounting plate 62, and the other end of the blocking bar 61 can be detachably connected to one or more positioning plates 5 along the X direction. Thus, the blocking bar 61 in the blocking structure 6 can rotate. Before the residual current circuit breaker A is installed, the blocking bar 61 can rotate to avoid the fixing structure 2. After the residual current circuit breaker A is installed, the blocking bar 61 can rotate to above the closing position of the residual current circuit breaker A to block the residual current circuit breaker A from detaching from the guide rail.
[0075] In addition, the blocking bar 61 in the blocking structure 6 of this application is fixed by means of the positioning plate 5, which has the effect of streamlining the structure.

One group of wiring holes 71 is used to install a group of wiring terminals, and each group of wiring terminals is used to connect a residual current circuit breaker A. Different groups of wiring terminals are connected to different test circuits.

Each wiring hole 71 is used to install a group of wiring terminals, and each group of wiring terminals is used to connect a residual current circuit breaker A. Thus, the multiple groups of wiring terminals are in a parallel relationship and have little influence on each other. When a problem occurs in one group of wiring terminals, it will not affect the operation of other groups of wiring terminals.
[0078] Please continue to refer to Figure 1 , in some embodiments of this application, the wiring hole 71 includes an input signal wiring hole and an output signal wiring hole. The input signal wiring hole and the output signal wiring hole are located on both sides of the fixing structure 2 in the Z direction.
[0079] Specifically, the input signal wiring hole and the output signal wiring hole are located on both sides of the fixing structure 2 in the Z direction. The wiring terminals of the input signal can be fixed at the input signal wiring hole, and the wiring terminals of the output signal can be fixed at the output signal wiring hole. Thus, it is convenient to connect the wiring terminals to the residual current circuit breaker installed at the fixing structure 2.
[0080] Please continue to refer to Figure 1 , in some embodiments of this application, if the residual current circuit breaker is a four-pole circuit breaker, then correspondingly, four wiring holes 71 can be provided above and below the fixing structure 2 respectively.
