Abstract
The utility model relates to a plastic casing type circuit breaker. The tripping system of the utility model comprises a magneticflux changer, a big bracket and a lever whose rotating shaft is fixed on the big bracket. Two vertical surfaces of the lever vertical to the bottom surface of the circuit breaker are provided with wing surfaces which extend towards the side surfaces and fixedly connect with the side vertical surfaces. The position of the magneticflux changer is that the side wing surfaces move along with the lever to directly or indirectly push the movable iron core of the magnetic flux changer. Because the utility model adopts the lever with wing surfaces, the lever to is pushed backwards by a handle, when the circuit breaker does the closing operation to make the lever rotate around the bracket anticlockwise, and draw an energy storage spring. Meanwhile, the wing surface on the right side of the lever drives a revolving plate to overturn and prop into the movable iron core in the magneticflux changer or the wing surface directly props into the movable iron core in the magneticflux changer. The attracting of the iron core of the magneticflux changer completes the resetting process. The resetting mode decreases the resetting power consumption, makes the resetting movement stable and reliable, increases the product reliability and decreases the volume of the plastic casing type circuit breaker.
Description
Affiliated technical field
The utility model belongs to a kind of circuit breaker, particularly relates to a kind of moulded case circuit breaker.
Background technology
Along with extensively being applied to rapidly in the low-voltage electrical apparatus field of electronic technology, intelligent circuit breaker is to answer the market demand and the novel breaker that is born, and its defencive function intellectuality, volume miniaturization, structure, accessory moduleization are inevitable development trend.Reset mode at present known moulded case circuit breaker magnetic flow convertor is to buckle the finger plate in the big support of bump in the process again by handle, and finger plate drives supporting plate and rotates.Supporting plate collides the moving iron core of magnetic flow convertor again, makes it adhesive and resets.Such reset mode power loss is big, intermediate link is many, thereby big reliability of products is lower.The space that resetting device occupies is also bigger.
The utility model content
The utility model provides for solving the technical problem that exists in the known technology that a kind of to have a space that reset powers is little, resetting device occupies less, and the steady moulded case circuit breaker of reliable reset.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it includes contact system, arc quenching system, operating mechanism and tripping system, and above-mentioned four parts all are fixed in the case for circuit breaker, in described tripping system and operating mechanism, include magnetic flow convertor, big support and rotation axis are fixed on the lever on the big support, be characterized in: the aerofoil that stretch out oriented side on vertical two side elevations in described lever and circuit breaker bottom surface is connected mutually with described side facade, the position of described magnetic flow convertor is the aerofoil of described lever side can directly or indirectly promote magnetic flow convertor with lever motion a moving iron core.
The utility model can also adopt following technical measures:
At described lever magnetic flow convertor one side is arranged, between the moving iron core of the aerofoil of lever and magnetic flow convertor, be equipped with finger plate.
At described lever magnetic flow convertor one side is arranged, the lever aerofoil be shaped as a bending side.
The advantage that the utlity model has with good effect is: because the aerofoil that is connected mutually with described side facade that adopts lever in the moulded case circuit breaker operating mechanism stretch out oriented side on its two side elevations vertical with the circuit breaker bottom surface, and the moving iron core of to be the aerofoil of described lever side can directly or indirectly promote with lever motion in the position of described magnetic flow convertor magnetic flow convertor.Circuit breaker drives lever to pusher with handle when closing operation like this, lever is rotated and the stretching energy-stored spring around the support inhour, the aerofoil on lever the right drives the moving iron core in the finger plate upset jacking magnetic flow convertor simultaneously, or the moving iron core in the direct jacking magnetic flow convertor, make the adhesive unshakable in one's determination of magnetic flow convertor, finish reseting procedure.It is to be converted into a transmission with encircling transmission that the utility model is compared with reset mode of the prior art more, and the power of will detaining has again reduced intermediate link directly by finger plate or directly pass to magnetic flow convertor.So not only reduced the reset powers loss, make homing action steadily, reliable, improved reliability of products greatly, and the also smaller volume that further reduces the plastic casing circuit breaker in space that occupies of resetting device.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, middle cover 1 is arranged on the plastic casing case for circuit breaker, middle cover 1 is screwed on shell.Lever 5 is fixed on the big support 6 by rotation axis, and big support 6 is fixed on the shell body 10 of circuit breaker.Lever 5 moving axis that can rotate rotates.The aerofoil 2 that oriented left and right sides face stretches out on vertical two side elevations in lever 5 and circuit breaker bottom surface is connected mutually with described side facade, support 3 is screwed on the bottom surface of circuit breaker middle cover 1 the right groove, with the axle with torsion spring, finger plate 7 and limit casing wears and with this axle be fixed on the support 3.The left side of finger plate 7 overlaps mutually with the right flank face 2 of lever 5, and moving unshakable in one's determination 8 of the back of its finger plate 7 and magnetic flow convertor 9 aligns.In the groove on circuit breaker middle cover 1 the right, the other end is not in the back of finger plate 7 for torsion spring one end, and the effect of torsion spring is to make its energy storage in reseting procedure, resets to make finger plate 7 self-returns after finishing.Reset mode is as follows: circuit breaker drives lever 5 to pusher with handle when closing operation, lever 5 is rotated and stretching energy-stored spring 4 around support 6 inhours, the aerofoil 2 on lever 5 the right drives finger plate 7 upsets simultaneously, moving unshakable in one's determination 8 of jacking magnetic flow convertor 9, make 13 adhesives moving unshakable in one's determination of magnetic flow convertor 9, finish reseting procedure.
In addition, also the aerofoil 2 of lever 5 can be extended for long straight plate shape by the above-mentioned straight plate shape of weak point or aerofoil 2 is extended for long straight plate shape and its end is bent into angle block of right angle shape.
