Description

TECHNICAL FIELD

[0002] Modular circuit breakers are electrical devices primarily used for protection and control of electrical circuits in power systems. They are typically designed to be combined and expanded as needed to accommodate different application scenarios.

At the same time, an energy storage compensation device is provided, which can detect and compensate the compression state of the closing spring, improving the ease of use and safety of the operating mechanism.

[0004] In the implementation of the above-mentioned patent, the operation of the energy storage compensation device is achieved through the meshing transmission between the gears. The driving gear structure is driven by the energy storage motor to rotate in the energy storage direction, thereby driving the driven part to rotate for energy storage. When the energy storage motor stops running, a locking part is provided to limit one-way rotation to prevent the driving gear from rotating in the opposite direction. This ensures that the driving gear only rotates in the energy storage direction.

The existing driving gear is of an integral structure and cannot be disassembled independently. Therefore, during replacement, other supporting parts need to be disassembled, making the device less convenient to maintain. SUMMARY
