[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] Example:
[0024] As attached Figure 1 To be continued Figure 5 As shown:
[0025] This utility model provides a simulated circuit breaker device, including an upper outer shell 1, a lower outer shell 2, and a test panel 4;
[0026] The upper outer shell 1 is provided with two sets of positioning parts 7, and the inner side of the positioning parts 7 is provided with a sealing ring B10. The lower outer shell 2 is placed at the lower end of the upper outer shell 1, and the rear end of the upper outer shell 1 and the lower outer shell 2 are rotatably connected. The front end of the lower outer shell 2 is provided with a handle, and two sets of positioning grooves 8 are provided on the upper side of the front end of the lower outer shell 2. The positioning parts 7 and the positioning grooves 8 are corresponding to each other. The rear end of the upper end of the lower outer shell 2 is provided with a groove. The rear end of the test panel 4 is placed in the groove on the rear end of the upper end of the lower outer shell 2 and is rotatably connected to the lower outer shell 2. The test panel 4 is movably locked on the inner side of the upper end of the lower outer shell 2. The test panel 4 is provided with five sets of closing test modules 5.
[0027] Among them, such as Figure 2 As shown, the inner side of the upper outer shell 1 is connected to two sets of elastic storage bags 6. Spare connecting cables or tools needed during the use of the equipment, such as screwdrivers, test pens and other commonly used tools, are stored in the two sets of elastic storage bags 6, which effectively improves the convenience and functionality of the equipment.
[0028] Among them, such as Figure 1 and Figure 3 As shown, the lower end of the lower outer shell 2 is provided with four sets of anti-slip pads 3, and the inner side of the lower outer shell 2 is connected with a sealing ring A9. The anti-slip pads 3 improve the stability of the present invention during use, and the sealing ring A9 helps the present invention to effectively block morning dew, rainwater and even salt fog moisture in coastal areas when used outdoors, avoiding the risk of short circuit caused by moisture in the internal circuit and improving the environmental adaptability of the equipment.
[0029] Among them, such as Figure 4 and Figure 5As shown, a connecting plate 11 is installed inside the bottom of the lower outer casing 2, and an electrical mounting rail 18 is connected to the connecting plate 11. Ten sets of DC relays 19 are installed on the electrical mounting rail 18. The rear end of the five-group closing test module 5 is provided with a set of position indicator lights 12 and a set of position indicator lights 13. The center end of the five-group closing test module 5 is provided with a set of positive interfaces 14 and a set of negative interfaces 15. The front end of the five-group closing test module 5 is provided with a set of position test line female connectors 16 and a closing test line female connector 17. The closing and opening test modules 5 are connected to the DC relays 19 through connecting lines. The closing branch is used for the closing state of this utility model, and the opening branch is used for the opening state of this utility model. The closing and opening states are determined by the closing state. The position indicator 13 and the open position indicator 12 provide a simple and clear display that is easy to identify. This avoids the adverse effects of repeated circuit breaker opening and closing caused by repeated whole-set tests, making it highly practical. Furthermore, components such as the electrical mounting rail 18 and the DC relay 19 are generally mass-produced general-purpose products with ample market supply and relatively low procurement costs. The design of the electrical mounting rail 18 makes the installation of the DC relay 19 simple and quick, requiring no complex installation tools or special installation techniques, thus reducing labor and time costs during installation and maintenance. At the same time, this standardized installation method also reduces the risk of component damage due to improper installation, thereby avoiding additional costs incurred due to repair or replacement of components.
[0030] The specific usage and function of this embodiment are as follows:

The closing branch is used for the closing status of this utility model, and the opening branch is used for the opening status of this utility model. The closing and opening status are displayed by the closing indicator light 13 and the opening indicator light 12. The circuit is simple, the display is clear and easy to identify, and it can avoid the adverse effects caused by repeated circuit breaker opening and closing caused by repeated whole-group tests. It has good practicality. In addition, this utility model has a lightweight structure, is easy to carry and transport, is suitable for testing work in outdoor substations, has low operating costs, and is suitable for simulation experiments of circuit breaker closing and opening in different occasions, with a wide range of applications.
[0032] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
