The utility model discloses an isolation arc extinguishing structure, including, the shell is equipped with the
accommodation cavity, and the
accommodation cavity inner wall is equipped with a plurality of recesss, and the
dynamic touch disc is contained in the
accommodation cavity, and the
dynamic touch disc is relative to the rotation of shell, and the
dynamic touch disc is fixed with the dynamic touch subassembly, and the number of static contact is two, and two static contacts are contained in the accommodation cavity, and two static contacts are respectively with dynamic touch subassembly cooperation, and the push element is connected with the dynamic touch disc, and the push element is relative to the rotation of dynamic touch disc, and the
slide plate is relative to the dynamic touch disc sliding, and the
slide plate is linked with push element, and when the dynamic touch disc rotates, the push element is matched with the recess, and the push element rotates and drives the
slide plate movement, and this kind of structure, need not the
elastic energy storage device, only through mechanical connection forms the
reciprocating motion of slide plate to the effective increase
arc length, improves arc extinguishing effect.
