[0002] In the power system, power switches are key devices for controlling, protecting and isolating circuits. However, traditional power switches have some shortcomings in terms of external impact, false triggering, and maintenance and repair. These problems include:

[0003] Lack of shock absorption mechanism: Traditional power switches usually do not have specially designed protection mechanisms. Once subjected to external shocks, they are prone to damage or false triggering, which in turn affects the normal operation of the power system.

[0004] Inconvenient maintenance and inspection: The maintenance and inspection process of traditional power switches is relatively cumbersome, requiring professionals to open the casing for operation, which increases the difficulty and time-consuming nature of maintenance.

[0005] Lack of buffer design: Most existing power switch protective covers lack a dedicated buffer mechanism and cannot effectively absorb external impacts, which can easily cause equipment damage.

[0006] Lack of comprehensive protection: Some protective covers are not designed comprehensively and fail to effectively prevent the impact of external objects on the switch, limiting its application in harsh environments.

[0007] Therefore, the present invention proposes a power switch protective cover which is convenient for maintenance to solve the above problems. Utility Model Content
