Abstract
The utility model relates to an arc striking mechanism of a low-voltage apparatus breaker, which comprises a short arc striking piece and an arc angle piece, the outer side of an arc extinguishing chamber is provided with an arc striking piece, one end of the arc extinguishing chamber is provided with a static contact, the outer side of the arc striking piece is provided with the short arc striking piece, and one side of the static contact is provided with the arc angle piece. The utility model has the advantages that because the existing arc striking piece and the existing static contact are respectively provided with one short arc striking piece and one arc angle piece, thus the arc striking intensity is enhanced, and the arcing time is shortened, and the breaking protective action of a breaker can be achieved.
Description
Technical field
The utility model relates to release unit, relates in particular to a kind of low-voltage electrical apparatus circuit breaker striking mechanism.
Background technology
The arc leading and suppressing structure of more existing miniature circuit breakers mainly is made up of moving contact, fixed contact, striking gusset and arc control device, and the electric arc that produces during disconnection extinguishes by drawing gusset introducing arc control device.But the fixed contact and the distance between the arc control device of existing homogeneous structure are bigger, and the distance of striking is long, cause electric arc to arc control device striking difficulty, striking intensity is lower, the arcing time is longer, breaking capacity is relatively poor, contact of breaker is easily by electrical arc erosion.
The utility model content
At above defective, the utility model provides a kind of Stability Analysis of Structures, can strengthen striking intensity, shortens the low-voltage electrical apparatus circuit breaker striking mechanism of arcing time, thereby can improve the high breaking capacity of circuit breaker.
For achieving the above object, the utility model is by the following technical solutions:
A kind of low-voltage electrical apparatus circuit breaker striking mechanism comprises short striking sheet and arc angle sheet, and the arc control device outside is provided with the striking sheet, and an end of arc control device is provided with fixed contact, and described striking sheet outer fix is provided with a short striking sheet, and the first side of described stationary contact is provided with the arc angle sheet.
The beneficial effect of low-voltage electrical apparatus circuit breaker striking described in the utility model mechanism is: by in existing striking sheet position and the fixed contact place increase the short striking sheet of a slice and an arc angle sheet respectively, thereby strengthen striking intensity, shorten the arcing time, help finishing circuit breaker fast to reach the high breaking protective effect.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the described low-voltage electrical apparatus circuit breaker of a utility model embodiment striking structural scheme of mechanism;
Fig. 2 is that the short striking chip architecture of the described low-voltage electrical apparatus circuit breaker of the utility model embodiment striking mechanism is provided with partial schematic diagram;
Fig. 3 is that the arc angle chip architecture of the described low-voltage electrical apparatus circuit breaker of the utility model embodiment striking mechanism is provided with partial schematic diagram.
Among the figure:
1, bottom; 2, fixed contact; 3, lack the striking sheet; 4, arc angle sheet; 5, arc control device; 6, spring; 7, connecting rod; 8, handle; 9, push rod; 10, snap close; 11, striking sheet.
Embodiment
As Figure 1-3, the described low-voltage electrical apparatus circuit breaker of the utility model embodiment striking mechanism, comprise short striking sheet 3 and arc angle sheet 4, arc control device 5 outsides are provided with bottom 1, its inboard is provided with striking sheet 11, described striking sheet 11 outer fix places are provided with a short striking sheet 3, described striking sheet 3 two ends lean on former striking sheet 11 and its middle part segmental arc forms and moulds on the shell outside being stuck in behind arc sheet central point, by three-point fix, can make more large-area electric current attract electric arc to guide to fast to reach effective arc quenching effect in the arc control device by producing more magnetic fields fast like this; One end of arc control device 5 is provided with fixed contact 2, and these fixed contact 2 positions are provided with an arc angle sheet 4.During work, under the normal operation of circuit breaker, press fixed handle 8 operating mechanisms, make power connection, tripping mechanism locking this moment, fixed contact 2 is failure to actuate, when current overload, the bimetal leaf of overload release produces deformation, and drivening rod 7 promotes snap close 10, and circuit breaker tripping is disconnected; When short circuit current when the electromagnetic system, moving iron core is inhaled, by push rod 9, promotes snap close 10, makes circuit breaker tripping, contact is finished circuit breaker disjunction protective effect under the effect of retracting spring 6 and disconnect.
Claims (1)
