Connecing, electromagnetic system end connects static contact 13, and end of incoming cables conductive component 11 connects has moving contact 14, moving contact 14 to arrange
At operating mechanism, operating mechanism drives moving contact 14 to be rotatably assorted with static contact 13.
Described operating mechanism includes handle 21 and the contact rack 22 being hinged on housing 1, and is hinged on contact rack 22
Snap close frame 23 and tripping frame 24, and the reset tension spring 25 being connected with contact rack 22.Described moving contact 14 is fixed on contact
On frame 22, contact rack 22 and tripping frame 24 thereon are connected by handle 21 connecting rod with handle 21, snap close frame 23 and described jumping
Buckle frame 24 snap close is connected.Described end of incoming cables conductive component 11 connects moving contact 14 by sheet metal 15, snap close frame 23 be provided with
The dropout hook 26 that sheet metal 15 is oppositely arranged.When circuit overloads, sheet metal 15 heating bending touching dropout hook 26, and solve
Snap close relation except snap close frame 23 with tripping frame 24.Described electromagnetic system includes stem stem 27, and is wound around the line that stem stem 27 is arranged
Circle group 28, and the push rod 29 being axially located in stem stem 27.Described push rod 29 is axially facing described snap close frame 23, when circuit is short
Lu Shi, push rod 29 axially promotes snap close frame 23, and releases the snap close relation of snap close frame 23 and tripping frame 24.
In said structure, chopper can carry out disjunction to circuit under short-circuit condition and overload, has disjunction effect
