Abstract
The utility model discloses an arc extinguishing system for a moulded case circuit breaker, which comprises an arc extinguishing cover and a fixed contact with a static contact. The arc extinguishing cover comprises a shell and a plurality of arc extinguishing grid plates embedded in the shell. Each arc extinguishing grid plate is arranged at the same side of the static contact. The tail end of the lowermost arc extinguishing grid plate, which is close to the static contact, is provided with an arcing ring which is inclined and extends downwards. The arc extinguishing system for the moulded case circuit breaker is simple and convenient to operate in the assembling process and the manufacturing cost of the integral arc extinguishing system can be effectively reduced.
Description
Technical field
The utility model belongs to the arc extinguishing technical field, is specifically related to a kind of arc quenching system that is used for breaker of plastic casing.
Background technology
Fig. 1 and Fig. 2 have shown a kind of traditional arc quenching system that is used for breaker of plastic casing, and this kind arc quenching system comprises fixed contact (5), striking part (6) and the arc-extinguish chamber (4) that is provided with fixed contact (51); Said arc-extinguish chamber (4) comprises housing (1) and is embedded in a plurality of arc extinguishing grid pieces (2) in the housing (1); The basic configuration of said striking part (6) is the V font, and on fixed contact (5), the other end points in the arc-extinguish chamber (4) arc extinguishing grid pieces (2) of below to the one of which end through screw; This kind arc-extinguish chamber (4) must with the supporting use of external striking part (6), reserve installation site and installing hole so need go up to striking part (6) at fixed contact (5), can increase the manufacturing process and the manufacturing cost of fixed contact (5), also wasted material.
Summary of the invention
It is comparatively easy and reduce the arc quenching system that is used for breaker of plastic casing of whole cost that the purpose of the utility model provides a kind of assembly operation.
The technical scheme that realizes the utility model purpose is: a kind of arc quenching system that is used for breaker of plastic casing comprises arc-extinguish chamber and the fixed contact that is provided with fixed contact; Said arc-extinguish chamber comprises housing and is embedded in a plurality of arc extinguishing grid pieces in the housing; Said each arc extinguishing grid pieces is arranged on the same side of fixed contact; Being positioned at, an arc extinguishing grid pieces of below is provided with towards the arc leading angle that extends below at its end near fixed contact.
In the such scheme, an arc extinguishing grid pieces that is positioned at the top is provided with the arc leading angle that inclination is extended up at its end near external fixed contact.
In the such scheme, said arc leading angle is that the part plate body bending of this arc extinguishing grid pieces forms.
The utlity model has positive effect: in (1) the utility model; Through an arc extinguishing grid pieces of below is provided with towards the arc leading angle that extends below at its end near external fixed contact being positioned at; Make it can be directly from the fixed contact striking; Thereby it is no longer need a striking part be set in addition separately, thereby comparatively easy and can effectively reduce the whole manufacturing cost of arc quenching system in the time operation of assembling arc quenching system as traditional arc quenching system.

Embodiment
(embodiment 1)
Fig. 3 to Fig. 4 has shown a kind of embodiment of the utility model, and wherein Fig. 3 is a kind of perspective view of the utility model; Fig. 4 is a kind of perspective view of arc quenching system shown in Figure 3 during from another viewed.
Present embodiment is a kind of arc quenching system that is used for breaker of plastic casing, sees Fig. 3 and Fig. 4, and this arc quenching system comprises arc-extinguish chamber 4 and the fixed contact 5 that is provided with fixed contact 51; Said arc-extinguish chamber 4 comprises housing 1 and is embedded in a plurality of arc extinguishing grid pieces 2 in the housing 1; Said each arc extinguishing grid pieces 2 is arranged on the same side of fixed contact 51; Being positioned at, an arc extinguishing grid pieces 2 of below is provided with towards the arc leading angle 3 that extends below at its end near fixed contact 51.An arc extinguishing grid pieces 2 that is positioned at the top also is provided with the arc leading angle 3 that inclination is extended up at its end near external fixed contact 51.The part plate body bending that said arc leading angle 3 is these arc extinguishing grid pieces 2 forms.
In the present embodiment; Through an arc extinguishing grid pieces 2 of below is provided with towards the arc leading angle 3 that extends below at its end near external fixed contact 51 being positioned at; Make it can be directly from the fixed contact striking; Thereby it is no longer need a striking part be set in addition separately, thereby comparatively easy and can effectively reduce the whole manufacturing cost of arc quenching system in the time operation of assembling arc quenching system as traditional arc quenching system.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the execution mode of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all execution modes.And conspicuous variation that these connotations that belong to the utility model are extended out or change still belong to the protection range of the utility model.
