Though described like this frame-type circuit breaker body is in off state, the high-intensity magnetic field that short circuit this moment causes disappears, and described magnetic conduction rotating part 23 resets under the effect of described back-moving spring 251.But because self-locking block 21 stretches out the breach 221 on the described self-locking shell 22, described self-locking end can't be separated with described self-locking short slot 2471, described like this rotating shaft 245 can't be rotated, described like this triggering portion 246 is still by on the press section that is pressed on the described triggering switch block 37, thereby forms self-locking.
See also shown in Fig. 9 A and Fig. 9 B, it is respectively the frame-type circuit breaker short-circuit condition that the utlity model has mechanical short circuit self-locking function back cross-sectional schematic and short-circuit condition generation rear side viewing schematic diagram takes place; It is through artificial with described self-locking block 21 by getting back in the described self-locking shell 22, described self-locking end is separated with described self-locking short slot 2471, like this by the back-moving spring in the rotating shaft that is arranged on described first STATEMENT OF FEDERALLY SPONSORED 241 252 make on described triggering portion 246 and the described triggering switch block 37 pressing part from, realize release, could realize then closing a floodgate once more.
And under situation about being short-circuited, cause the action of opening circuit, stretch out from the breach 221 on the described self-locking shell 22, played indicative function by described self-locking block 21.
The above only is preferred embodiment of the present utility model, only is illustrative for the utility model, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes to it in the spirit and scope that the utility model claim is limited, revise, even equivalence, but all will fall in the protection range of the present utility model.
