After the overhead line fault is cleared, closing the circuit breaker in a short time, namely reclosing and reclosing; reclosing is one of the self-recovery power supply methods commonly employed in operation, since in practice most overhead line faults are transient or temporary. The closing mechanism of the circuit breaker is actually a tripping mechanism, and the closing or opening of the circuit breaker requires the mechanism to provide enough operating energy, the energy storage mechanism stores energy (stretching or compressing) for the spring before closing and enables the mechanism to be stabilized at a dead point, and when the closing mechanism is closing, the energy storage mechanism is separated from the dead point to rapidly release the spring energy, so that closing is completed. And energy is stored for the opening spring while the switch is switched on, and the opening is completed when the opening mechanism is tripped. Therefore, energy must be stored for closing. After the circuit breaker with the automatic reclosing function completes the closing (the energy storage spring is released), the circuit breaker can also store energy, and the rapid reclosing function can be completed.

Detailed Description
The present invention will be further described with reference to the following examples.
Examples
As shown in fig. 1-3, a structure of a load switch for preventing reclosing after closing mainly includes an output shaft 1, an output crank arm 9 connected to the output shaft 1 in a transmission manner, and an energy storage mechanism, where the output shaft 1 is connected to a transmission portion, which is irrelevant to the technical problems to be solved by the present application in the prior art, and no detailed description is given here, a closing roller 3 and a holding roller 4 are movably connected to the output crank arm 9, and the output crank arm 9 is in transmission engagement with the output shaft 1 through a flat key 2, where the energy storage mechanism mainly includes a driving wheel 7 and a driving claw 8, and when the driving claw 8 is in engagement with the driving wheel 7, the energy storage mechanism is normally storing energy, and when the driving claw 8 is in a separated state from the driving wheel 7, the energy storage mechanism cannot store energy, and in this embodiment, an arc block 6 for pushing the driving claw 8 to separate from the driving wheel 7 is fixed on a side surface of the output shaft 1, and after the arc block 6 and the output shaft 1 are fixed, the arc block 6 at least partially protrudes out of the side surface of the output shaft 1. In this embodiment, the inner side of the tripping arc block 6 is a plane, the outer side of the tripping arc block is an arc surface, the inner plane is arranged to be conveniently and stably fixedly connected with the output shaft 1, and the outer side of the tripping arc block adopts an arc surface structure to conveniently push the driving claw 8. Compare traditional cam structure, processing and simple to operate are simpler, swift, have alleviateed product weight simultaneously, have reduced the consumptive material, and manufacturing cost is lower relatively.
In order to facilitate installation of the trip arc block 6, in this embodiment, a notch is formed in the side surface of the output shaft 1, and the trip arc block 6 is embedded in the notch and fixed on the output shaft 1 through a fastening member.
