Detailed Description

As shown in fig. 3, the energy storage device includes a holder 1, a guide bar 2, a holder 3, and a spring 4, which are combined as shown in fig. 1 and 2.

As shown in fig. 4, which is a cross-sectional view of the holder 1 of the present device, the holder 1 includes a hollow cylindrical sleeve 101, a first spring limit feature 103 protruding outward is provided at one end of the sleeve 101, and a boss limit feature 102 protruding inward is provided at an end surface of the sleeve 101 at the other end of the sleeve 101, so that a vertical sectional area at the boss limit feature 102 is smaller than a vertical sectional area of the sleeve 101.

As shown in fig. 5 and 6, in a cross-sectional view and a side view of the guide rod 2 of the apparatus, one end of the guide rod 2 is provided with a slider 201 protruding outward, the other end is provided with a groove limiting feature 204, and an end surface of the groove limiting feature 204 is provided with a first cylindrical groove 203 recessed inward for connecting with an energy storage operating system body in a circuit breaker. An inwardly recessed groove 202 is provided at the junction of the groove stop feature 204 with the guide bar 2.

As shown in fig. 7, which is a cross-sectional view of the bracket 3 of the present device, the whole of the bracket 3 is hollow cylindrical, the outer periphery of the bracket is provided with a second spring limiting feature 301 protruding outwards, and a hollow part inside the bracket 3 is provided with a boss 302 matching with the groove limiting feature 204 of the guide rod 2.
