Fig. 4 is the structural representation of moving iron core in the utility model.
Among the figure, Shell of circuit breaker 1, static iron core 2, iron core part 21, open slot 211, standing part 22, moving iron core 3, rotational support 31, stopper slot 32, leg 33, row's formula lead 4, elastic component 5, bimetallic element 6, block 7.
Embodiment
Be described further to the embodiment of accompanying drawing below the utility model:
Shown in figure, this is used for the separation type suction type instantaneous release of circuit breaker, and said release is located in the storage tank 11 of Shell of circuit breaker 1; Comprise static iron core 2, moving iron core 3, row's formula lead 4 and elastic component 5, said static iron core 2 comprises iron core part 21 and standing part 22, and said iron core part 21 is provided with open slot 211; Said row's formula lead 4 passes open slot 211; Said standing part 22 outwards folds along iron core part 21, and said standing part 22 is provided with and is fixed on the Shell of circuit breaker 1 screw hole, and said moving iron core 3 is positioned at the notch side of open slot 211; The top of moving iron core 3 is for driving the eave tile of circuit breaker tripping; Elastic component 5 adopts springs, and an end of spring is fixed on the through hole on the iron core part 21, and the other end is fixed on the moving iron core on 3 the through hole; The both sides of said moving iron core 3 are provided with rotational support 31; Storage tank 11 two sides of said Shell of circuit breaker 1 are provided with stopper slot 32, and rotational support 31 is positioned at stopper slot 32 and can rotates at stopper slot 32, and the both sides of said storage tank 11 are provided with and move the spacing block that cooperates 7 of iron core 3 lower end legs, 33 formations.Put into stopper slot 32 to rotational support 31, adopt block 7 effects to block the leg 33 of moving iron core 2 lower ends, thereby effectively anti-stop iron core 2 is because the installation that the effect wallowing motion of spring causes is unstable.During short circuit, the electric current of the row's of flowing through formula lead is bigger, makes static iron core 2 places produce strong magnetic field, thereby inhales moving iron core 3, and moving iron core 3 rotates the dropout that realizes circuit breaker around stopper slot 32.Adopt such scheme; Owing to be installed on the Shell of circuit breaker 1 to the moving iron core 3 on the release; Replaced existing employing metallic support that the inconvenience that brings is installed; Thereby make installation simple, convenient, and need not to adopt support to make production cost effectively reduce, help bringing benefit to Production Gain and resource savings.Shown in figure, the row's formula lead 3 between said moving iron core 3 and the static iron core 2 is provided with bimetallic element 6.When current overload occurring in the circuit, this moment, bimetallic element 6 heated bendings also can make release thread off, can short-circuit protection thereby realize, and again can overload protection.
Shown in figure, said static iron core 2, row's formula lead 3 and bimetallic element 6 are riveted mutually.Be riveted together static iron core 2, row formula lead 3 and bimetallic element 6, can effectively prevent owing to connect the insecure problems such as circuit contacts is bad that cause.
Embodiment should not be regarded as the restriction to utility model, but any improvement of doing based on the spirit of the utility model, all should be within the protection range of the utility model.
