Embodiment Construction
[0019] Examples of self-powered circuit breakers, such as figure 1 As shown, other structures of the self-energized circuit breaker are all prior art, so the structure of its cylinder assembly is mainly introduced here. The cylinder assembly includes a compression chamber cylinder 11 and an expansion chamber cylinder 12, wherein one end of the compression chamber cylinder 11 passes through The valve seat 13 is closed, and the other end is an open structure. In this embodiment, the valve seat 13 is fixedly assembled in the compression chamber cylinder 11 through a top screw, wherein the top screw holes on the compression chamber cylinder 11 have two rows, two rows The top wire holes are distributed along the axial direction of the cylinder 11 in the compression chamber, and are mainly used to adjust the position of the valve seat 13. A raised compensation structure 131 is provided on the inner side of the valve seat 13. In this embodiment, the compensation structure 131 It is i...
